DETAILED DESCRIPTION OF THE INVENTION The present invention provides an electric coil for converting current into mechanical force, a mechanical element that operates in response to the mechanical force,
and to an actuator comprising a printed circuit board, and in particular to a connector for connecting the actuator to an external electrical cable.

There are various types of electromagnetic pressure control devices that control fluid pressure by including an actuator, such as a solenoid device, a valve member driven by the solenoid device, and a printed circuit board equipped with an electric circuit or an electronic control device that controls the energization of the solenoid device. There are different structures and uses, and electrical control is performed depending on the structure and use. For example, in one aspect of vehicle constant speed control, a solenoid device opens and closes a negative pressure port and an atmospheric pressure port to control the negative pressure in a pressure control chamber between a spring-biased diaphragm and a housing. , an electromagnetic pressure control device that opens and closes the throttle valve of the engine using motion corresponding to the negative pressure, and a vehicle speed sensor and an instruction switch that memorize the vehicle speed at that time when constant speed driving is instructed, and Thereafter, an electronic control device is used to control the energization of the electromagnetic pressure control device so that the vehicle speed becomes the stored value until the constant speed driving instruction is canceled. Hereinafter, one type of electromagnetic pressure control device used for this type of constant speed running, namely an actuator,
The explanation will be explained using as an example.

FIG. 1 shows the configuration of the electronic control device, and FIG. 2 shows the configuration of the actuator.

In this example, the electronic control device 10 is mainly configured with a 1-chip microcomputer (or 1-chip microprocessor) CPU.
A runaway detection circuit 20 is connected to the reset port RESET of the CPU, and an external interrupt input port
IRQ, input ports K2, K3, K0 and K1 have interface circuits IF1, IF2,
Vehicle speed detection reed switch SW2 and clutch switch are connected via IF3, IF3, IF4 and IF5.
SW3, stop switch SW4, set switch SW5 and resume switch SW6 are connected.

Near the vehicle speed detection reed switch SW2,
A permanent magnet connected to a speedometer cable (not shown) is arranged, and when the vehicle moves and the permanent magnet rotates, the contacts of SW2 open and close accordingly. When the contact of SW2 changes from closed to open, the output level of the interface circuit IF1 becomes low level L, and an interrupt request is issued to the microcomputer CPU. The CPU counts up the number of times the level becomes low in the interrupt process, and every predetermined period of time takes the count value into a register as a vehicle speed value.
Clear the counter value and count up again using an interrupt.

Clutch switch SW3 opens and closes in conjunction with the vehicle's clutch pedal, and stops switch SW4
opens and closes in conjunction with the vehicle's brake pedal. A stop lamp is connected to the stop switch SW4, and the stop lamp lights up when SW4 is turned on (closed).

The set switch SW5 and the resume switch SW6 are push button switches, and are arranged at positions on the instrument panel where they can be easily operated by the driver.

The output port _O0 of the microcomputer CPU is connected to the runaway detection circuit 20, and the output port
O ₂ and O ₃ each have a solenoid driver
DV1 and DV2 are connected. driver DV
A negative pressure control solenoid SL ₁ (electric coil) of the actuator, which will be described later, is connected to the output of the driver DV 1, and a negative pressure release solenoid SL ₂ (electric coil) is connected to the output of the driver DV2.

The negative pressure control solenoid SL ₁ , the negative pressure release solenoid SL ₂ , and the constant voltage power supply circuit 30 that generates the constant voltage Vcc include an ignition key switch SW.
1, voltage from the vehicle battery is applied. The circuit 40 is for energizing the release solenoid SL ₂ separately from the operation of the CPU when the brake is applied.

FIG. 2 shows the configuration of a conventional actuator 100 controlled by the electronic control device 10 of FIG. 1. As shown in FIG.
This will be explained with reference to FIG. Housing 101
consists of two parts 101a and 101b. The diaphragm 102 has two parts 101a
and the flange portion of Y101b.
A space surrounded by the diaphragm 102 and the housing 101a is a negative pressure chamber, and a space surrounded by the diaphragm 102 and the housing 101b is an atmospheric chamber communicating with the atmosphere. 103 is housing 1
This is a compression coil spring inserted between Ola and the diaphragm 102, and pushes the diaphragm 102 back to the position of the imaginary line when the pressure in the negative pressure chamber is close to atmospheric pressure. A rod 104 fixed near the center of the diaphragm 102 is connected to a link of a throttle valve 105. Housing 1
01a is provided with a negative pressure intake 107 (negative pressure port) communicating with the intake manifold 106, and atmospheric air intakes 108 and 109 (atmospheric ports).

110 is a negative pressure control valve, and 111 is a negative pressure release valve, both of which are fixed to the housing 101a. Movable piece 112 of negative pressure control valve 110
is tiltable about P as a fulcrum, one end is connected to the tension coil spring 113, and the other end faces the negative pressure control solenoid _SL1 . Both ends of the movable piece 112 function as valve bodies, and they open the negative pressure intake port 107, close the atmospheric air intake port 108 (the state shown in the figure) _, or close the negative pressure intake port 107 in response to energization and de-energization of the solenoid SL 1. Blockage, air intake 1
08 open.

Similarly to the negative pressure release valve 110, the movable piece 11
4, has a tension coil spring 115 and a solenoid SL ₂ , but the movable piece 114 is connected to the atmospheric air intake 1
09 is closed (state shown) or opened. Note that 116 is an accelerator pedal, and 117 is a tension coil spring.

A conventional actuator is constructed as described above and driven by an electronic control device shown in FIG.

Further, in this conventional example, the electronic control device and the actuator were configured separately and placed in the vehicle. Therefore, the actuator 100 has 3
The actuator connector was extremely simple, just connecting the main electrical cable.

However, in recent years, with the advancement of vehicle automation, a large number of various devices are placed in various parts of the vehicle, resulting in increased demands for reduced installation space, cost reduction, and single componentization. Concentrating all on-board electronic control in one place and one set of computers not only complicates electrical wiring and component configurations, but also makes parts that can be commonly used in different vehicle models. The situation has become such that various demands and problems are possible, such as a decrease in the number of vehicles produced and a greater disadvantage in car manufacturing.

Therefore, it may be possible to integrate the actuator with an electric circuit such as a transistor circuit (coil driver) that energizes the electric coil of the actuator, or an electronic control device that performs judgment, calculation, etc. in addition to the coil driver. . In other words,
It is conceivable that the mechanical unit parts used to control each part and the electrical circuit or electronic control device used for energizing them, or for energizing and controlling them, be integrated into one component. According to this, the functional design and assembly of the car will become medicine, such as having the same parts even if the car models are different, and making various automatic control parts optional even in the same car model.

However, for example, the above-mentioned actuator is disposed in the engine room of a vehicle, and the ambient temperature therein is relatively high, which poses a problem in the heat resistance of the semiconductor elements of the electronic control device. In other words, since semiconductor elements generally have a low heat resistance, it is difficult to attach them directly to the actuator.Also, it is possible to use semiconductor elements with high heat resistance, but this is expensive and difficult to install automatically. When integrated with control mechanical parts, there is a temperature problem.

Therefore, in order to improve the temperature resistance, a fluid flow path is formed in the part of the actuator housing where the electronic control device is attached, and one of the front and back surfaces of the heat sink is faced to this fluid flow path, and the other side is In addition to fixing the electronic control device, a printed circuit board incorporating the electronic control device is bonded to a heat sink, such as by forming a protrusion on the surface of the heat sink facing the fluid flow path to help dissipate heat. It is preferable that the heat emitted by the electronic control device be absorbed by the heat sink, and the heat of the heat sink be absorbed by the fluid in the fluid flow path to prevent the electronic control device from overheating.

In any case, when the actuator is provided with a printed circuit board, it is necessary to connect the printed circuit board and an electric coil (solenoid) within the actuator, and to connect the printed circuit board and an external electric cable.

The connection between the printed circuit board and external electrical cable is
This can be done relatively easily with a connector. For example, the connection terminal inside the actuator (external connection terminal) of the connector attached to the actuator.
It is sufficient to arrange the terminals in the same manner as the corresponding connection terminals on the printed circuit board, and connect the terminals at a plurality of locations at the same time using automatic soldering. However, the leads of the electric coil are soldered to the printed circuit board separately from the connector, so you have to rely on hand soldering, which makes the soldering work tedious, and the printed circuit board must be highly heat resistant. Wiring cannot be made very dense. In particular, when a printed circuit board is fixed to a heat sink that helps dissipate heat from an electric circuit or an electronic control device, electrical connection between the electric coil of the actuator and the printed circuit board becomes difficult.

The present invention provides an actuator in which an electric coil and a printed circuit board can be connected simultaneously at substantially the same position as the connection between an external connection terminal of a connector and a printed circuit board, and automatic soldering can be performed. With the goal.

In order to achieve the above object, in the present invention,
A connector body that has an end that receives an external connector that connects the actuator connector to the actuator and an end that extends inside the actuator housing; an external connection terminal conductor arranged to correspond to the connection terminals of the connector body;
an internal connection terminal conductor, one end of which is arranged in line with the external connection terminal conductor to correspond to the connection terminals of the printed circuit board, and the other end of which is arranged to connect to the lead of the electric coil inside the actuator housing; shall be prepared.

That is, outside the external connection terminal conductor that connects the external electrical cable to the connection terminal on the surface of the actuator's printed circuit board, an electric coil is connected to the connection terminal of the printed circuit board inside the actuator, although it is not connected to the external electrical cable. The internal connection terminals are also integrated with the connector, and one end of the internal connection terminals is also aligned with the external connection terminals in an arrangement corresponding to the connection terminals on the surface of the printed circuit board.

According to this, after the lead of the electric coil is pre-soldered to the other end of the internal connection terminal using hand soldering, etc., both the external connection terminal and the internal connection terminal are simultaneously soldered to the connection terminal of the printed circuit board using automatic soldering. A printed circuit board with relatively low heat resistance and high density wiring suitable for automatic soldering can be used, and the electrical connection work of the actuator is simple and easy. Since the wiring of the printed circuit board can be made high-density, it is possible to downsize the electric element equipment section of the actuator. Furthermore, since the leads of the electric coil are not directly connected to the printed circuit board, the electrical connection of the electric coil is mechanically stable and has high mechanical resistance such as vibration resistance.

3 and 4 are cross-sectional views of an actuator equipped with an embodiment of the present invention, and FIG. 5 is a bottom view of the housing of the embodiment. Figure 3 is 5th
This corresponds to a cross-sectional view taken along the - line in the figure, and FIG. 4 corresponds to a cross-sectional view taken along the - line.

The housing 201 of the actuator 200 is
It consists of two parts 201a and 201b.
The diaphragm 202 has two parts 201a and 201a.
It is held between the flange portions of 02b. A space surrounded by the diaphragm 202 and the housing 201a is a negative pressure chamber (pressure control chamber) 203, and a space surrounded by the diaphragm 202 and the housing 201b communicates with the atmosphere to form an atmospheric chamber 204.
A piston 205 is attached to the diaphragm 202, a rod 207 is fixed to the piston 205, and the rod 207 is connected to a throttle valve of the engine.

The diaphragm 202 is a compression coil spring 2
06 (first spring means), the diaphragm 202
and the atmospheric chamber 204 surrounded by the housing 201b is pushed in a direction (to the left). Therefore,
When the pressure in the negative pressure chamber 203 is close to the pressure in the atmospheric chamber 204, the biasing force of the coil spring 206 causes the diaphragm 202 to move as shown in FIG.
It is pushed all the way to the left. The rod 207 is connected to the throttle valve via a cable, ring, or the like.

The housing 201a is provided with a negative pressure port 208 that communicates with a negative pressure source such as an intake manifold, and an atmospheric pressure port 209 that communicates with the atmosphere via a filter (not shown).

A negative pressure control valve 210 and a negative pressure release valve 211, which are two flow rate control valves, are each fixed to the housing 201a. A tension coil spring 213 is attached to one end of the movable piece 212 of the negative pressure control valve 210.
(second spring means) is connected, and the other end faces negative pressure control solenoid SL ₁ , which is a control solenoid. Further, valves 2 are provided at both ends of the movable piece 212.
14 and 215 are fixed to each other, and in response to the energization and deenergization of the solenoid SL ₁ , they open the valve nozzle 215a communicating with the negative pressure port 208 and close the valve nozzle 214a communicating with the atmospheric pressure port 209. , or valve nozzle 215a
is closed, and the valve nozzle 214a is opened.

The negative pressure release valve 211 similarly has a movable piece 216, a tension coil spring 217 (second spring means), a solenoid SL ₂ , and valves 218 and 219 fixed to the movable piece 216, but the valve 219 is connected to the atmospheric port 209. Communicating valve nozzle 219
Perform only occlusion or initiation of a.

The bracket 226 is fixed to the housing 201a, and the gap between the bracket 226 and the housing 201a is molded 227 with epoxy resin or the like.

At the bottom of the housing 201a, an atmospheric pressure port 209 communicates with valve nozzles 214a and 219a. Zigzag labyrinth groove (fluid flow path) 22
8 is formed.

FIG. 6a shows the bottom surface of the heat sink 229, and FIG. 6b shows a cross-sectional view taken along the line -2. A large number of small protrusions 229a are formed on the surface of the heat dissipation plate 229 at positions that can fit into the labyrinth grooves 228. As shown in FIGS. 3 and 4, when the heat sink 229 is assembled to the housing 201a, the small protrusion 229a of the heat sink 229 enters into the groove 228 on the bottom surface of the housing 201a.

Next, an electronic control device 220 (a configuration similar to that shown by 10 in FIG. 1) is configured on a printed circuit board 221, and this printed circuit board 221
29, housing 20 via gasket 222
It is fixed to 1a. Lead terminals of a connector 225 are soldered to the printed circuit board 221. The leads 223 of the solenoids SL ₁ and SL ₂ are connected to the printed circuit board 221 via the connection terminals of the connector 225 .

FIG. 6c shows an enlarged view of the external appearance of the connector 225. This connector 225 is connected to the heat sink 22 described above.
The shape and connection terminal arrangement are suitable for connecting a plurality of switches and solenoids SL ₁ and SL ₂ shown in FIG.

That is, the electronic control device 220 (the first
Eight external connection terminal conductors 11, 12, 13, 14, 1 to connect external electrical leads to 10) in the figure.
5, 16, 21 and 22 are exposed, and these terminal conductors pass through the connector body to reach their penetrating ends 11a, 12a, 13a, 14a, 1
5a, 16a, 21a, and 22a are arranged in the same manner as the corresponding connection terminals on the printed circuit board 221, and are positioned slightly above the surface of the printed circuit board 221.

Codes 11a, 12a, 13a, 1 shown in FIG.
4a, 15a, 16a, 21a and 22a indicate electrical lines corresponding to these through ends.

Solenoids SL ₁ and SL ₂ are on the opposite side of the printed circuit board 221 with respect to the heat sink 229, so in order to connect the leads of solenoids SL ₁ and SL ₂ directly to the printed circuit board 221, through holes are required in the printed circuit board 221. Make an electrical connection between the back wiring and the front wiring by plating, and then solder the solenoid lead to the back wiring, or make a hole in the printed circuit board 221 for the solenoid lead to pass through, and pass the solenoid lead through the hole. 2
Soldering etc. is required on the front side of the printed circuit board 21, but if the back wiring is done, an insulating gap must be formed between the printed circuit board 221 and the heat sink 229, which makes the structure of the printed circuit board 221 complicated. Of course, there are problems in that the soldering work is troublesome and the heat dissipation effect is also reduced. Even when passing the solenoid lead through the printed circuit board, the connector terminal and the solenoid lead must be soldered to the printed circuit board in different locations.Since the printed circuit board is extremely small, soldering is troublesome, and the printed wiring is extremely high. The problem is that it cannot be made into a density.

Therefore, the connector 225 is provided with the above-mentioned through end 11.
a, 12a, 13a, 14a, 15a, 16a,
Eight external connection terminal conductors 11, 12, 13, 14, 15, 16, 2 having 21a and 22a

Terminal conductors 17 and 18 for connecting three solenoids pass through the connector end extending inside from the bottom to the top.
and 19, their terminal conductors 17,1
Solder the energizing leads 223 of solenoids SL ₁ and SL ₂ to the lower ends of solenoids 8 and 19, that is, the one for feeding power to SL ₁ is connected to the terminal conductor 18, the one for feeding power to SL 2 is connected to the terminal conductor 17, and the one for feeding power to SL ₂ is connected to the terminal conductor ₁₇ . Solder the earth return common to SL ₂ to the terminal conductor 19, and connect the upper ends 17a, 1 of the terminal conductors 17, 18, 19
8a, 19a to eight terminal conductors 11, 12, 1
Penetration ends 11a, 12a, 13a, 14a, 15a, 1 of 3, 14, 15, 16, 21 and 22
Similarly to 6a, 21a and 22a, the printed circuit board 22 is arranged in the same arrangement as these and at the same time.
The structure is such that one terminal conductor is soldered at the same time.

According to this, as shown in FIG.
25 to the housing 201a, and the solenoids SL ₁ and SL ₂ are installed inside the housing 201a.
By soldering the leads 223 to the lower ends of the terminal conductors 17, 18, 19 of the connector 225, the mechanical elements of the actuator 200 are assembled.

A heat sink 229 to which a printed circuit board 221 equipped with an electronic control device 220 is fixed is attached to the actuator semi-finished product of this type, and the connection terminal edges of the printed circuit board 221 are connected to the upper through-ends 11a, 12a of the connector 225. 13a, 14a, 15a, 1
6a, 21a and 22a and terminal conductor 1
7, 18, 19 and the housing 201
The heat dissipation plate 229 is inserted between the pedestal parts 225a of the protruding end inside the housing 201a, and the heat sink 229 is fixed to the housing 201a with screws, using an automatic soldering device.
Upper penetrating ends 11a, 12a, 13a, 14
a, 15a, 16a, 21a and 22a and the upper ends of the terminal conductors 17, 18, 19 are simultaneously soldered to the connection terminals of the printed circuit board 221.

This allows the printed wiring to be of high density and high integration, suitable for automatic soldering, with relatively low soldering heat resistance, and the soldering work becomes extremely simple.

After soldering in this manner, a mold 227 made of the aforementioned epoxy resin or the like is applied.

With the above configuration, the atmosphere flowing in from the atmospheric pressure port 209 passes through the opening 209a to the maze-like groove 22.
8 and absorbs the heat around the electronic control device 220 through the printed circuit board 221 and the heat sink 229, and the valve nozzles 214a and 219.
a and reaches the negative pressure chamber 203. Negative pressure chamber 20
When the valve 215 is open, the air of No. 3 is sucked into the intake manifold of the engine through the valve nozzle 215a and the negative pressure port 208.
Therefore, the electronic control device 220 is forcedly air-cooled.

The printed circuit board 221 is a ceramic printed circuit board in this embodiment, and has relatively high heat conductivity, so that the heat conduction from the electronic control device 220 to the heat sink 229 is relatively unobstructed. The heat dissipation plate 229 is made of aluminum whose surface has been anodized, and has high heat conductivity. In addition, the ceramic printed circuit board 221
Since this uses silver-palladium printed wiring, when soldering by hand, there is a high probability that the silver will separate from the wiring during soldering and migrate to the solder side, causing the wiring to break. Since electrical connections are made to the printed circuit board using automatic soldering, there is no problem like this.

The printed circuit board 221 may be made of a heat conductive material other than a ceramic printed circuit board, such as an aluminum plate whose surface has been anodized, coated with a heat-resistant resin as needed, and printed wiring on top. Other printed circuit boards with high resistance may also be used.

In the actuator having the above configuration, as clearly shown in FIG. 5, a negative pressure port 208 for supplying negative pressure, an atmospheric pressure port 209 for supplying atmospheric pressure, an external sensor, and a power line are connected to the actuator. The connector 225 for
To make the piping and cable arrangement simple and easy, they are all located at the lower end of the housing 201a and all face in the same direction. This standardizes the actuator as an automatic control unit, making it easy to install and remove it on the vehicle. Piping and wiring to the actuator can be done as a cable unit that integrates a fluid pipe and an electric cable.

The configuration of the electronic control device 220 is the same as the configuration and control operation of the electronic control device 10 shown in FIG. 1, and the control operation is the same as that of the electronic control device 10 shown in FIG.
As shown in Figure c. This control operation is the same as the vehicle speed control disclosed and explained in Japanese Patent Application No. 58-34286, which the present applicant has already applied for, and moreover, it is obvious from FIGS. 7a to 7c.
Detailed explanation will be omitted.

In the above embodiment, the actuator is controlled by negative pressure, and the labyrinthine groove (fluid flow path) 228 communicates with the atmospheric pressure port 209, but the actuator is not limited to this, and the actuator is controlled by positive pressure. Alternatively, the actuator may be an actuator that communicates with a negative pressure port, or the actuator may be an actuator that connects not only an electromagnetic pressure control device but also an electric coil such as a solenoid device or a motor. It may be other types that include a main driving source and mechanical elements driven by the driving source. In the above embodiment, the printed circuit board is equipped with an electronic control device that not only energizes the electric coil but also makes judgments and calculations to control the energization of the electric coil. The same method can be applied even when the board is equipped with only an electric circuit such as a coil driver that only energizes the electric coil. In other words, the present invention can be applied to any actuator that includes a printed circuit board.

As described above, according to the present invention, since the connector is provided with the terminal conductor for external connection and the terminal conductor for internal connection, and are arranged in the same position as their ends, one end of the terminal conductor for internal connection of the connector After connecting the coil leads, the terminal conductors for external and internal connections, whose ends are arranged in the same way as the connection terminals on the printed circuit board, are automatically soldered to all of the connection terminals on the printed circuit board at the same time. sell. Therefore, a small printed circuit board with relatively low heat resistance and relatively high density wiring can be used, and electrical connection work is simple and easy, and direct connection to the printed circuit board is prone to disconnection. The electrical coil lead connection has higher mechanical resistance and is less likely to break.
