Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a connector with a switch in which the connection of a switch terminal can be switched from a break terminal to a signal terminal of a plug by inserting a plug.

[0002]

2. Description of the Related Art A switch-equipped connector is interposed between, for example, a transmission / reception circuit of a mobile phone or PHS, which is normally connected to an attached antenna, for switching to the inspection device side of the transmission / reception circuit at the time of shipment. Has been done.

As shown in FIG. 16, a conventional connector 100 with a switch has a cylindrical insulating sleeve 101 at its tip.
The housing 101 has an insulative housing 101 having a. Inside the housing 101, the fixed contact portion 102a of the break terminal 102 and the movable contact portion 103a of the switch terminal 103 are provided.
A contact accommodating chamber 104 for accommodating is formed.
The signal terminal 1 of the plug 105 is provided on the front surface of the insulating sleeve 101a so as to communicate with the contact accommodating chamber 104.
The plug insertion hole 106 into which the plug 05a is inserted is bored, and the insulating sleeve 10 concentric with the plug insertion hole 106 is formed.
A cylindrical ground shell 107 is fixed around the periphery of 1a. The ground shell leg 107a behind the cylindrical ground shell 107 is exposed rearward from the rear surface of the housing 101 and is soldered to a ground pattern of a printed wiring board (not shown).

The break terminal 102 is composed of an elongated conductive leaf spring piece, and integrally includes a fixed contact portion 102a arranged in the front and rear direction in the contact accommodating chamber 104 and a break terminal leg portion 102b protruding from the rear of the housing 101. Have In addition, the switch terminal 103 is also formed of an elongated conductive leaf spring piece, and the movable contact portion 10 whose front end, which is double folded in the contact accommodating chamber 104, faces the plug insertion hole.
3a and a switch terminal leg portion 103b protruding from the rear of the housing 101. By thus folding back the base end of the movable contact portion 103a,
The movable contact portion 103a is always in elastic contact with the fixed contact portion 102a.

When the plug 105 is inserted into the switch connector 100, the ground terminal 105b around the plug 105 elastically contacts the cylindrical ground shell 107, and the central signal terminal 105a contacts the movable contact portion 103a of the switch terminal 103. Makes elastic contact. At this time, the movable contact portion 103a is bent to the right in the figure by coming into contact with the signal terminal 105a, and the connection with the fixed contact portion 102b is cut off.

Therefore, the switch terminal 103 is connected to the mobile phone,
By connecting the antenna of the PHS transmitter / receiver to the break terminal 102 and connecting the inspection circuit of the transmitter / receiver to the signal terminal 105a of the probe 105, which is a plug,
The probe 105 can be connected to the switch-equipped connector 100 only when the transmission / reception circuit is inspected, and the inspection circuit can be connected to the transmission / reception circuit.

[0007]

However, in order to continuously inspect a large number of transmission / reception circuits, the insertion of the probe (plug) 105 electrically connected to the inspection circuit into the switch-equipped connector 100 is automated, The switch-equipped connector 100 is inserted from above, which is orthogonal to a printed wiring board (not shown) to which the connector 100 is attached.

A switch terminal 103 which is an elongated leaf spring piece.
Are arranged along the insertion direction of the plug 105, that is, in the vertical direction in order to convert the relatively rough insertion stroke of the plug 105 into the bending of the switch terminal 103 in the direction orthogonal thereto, but the switch terminal 103 If the movable contact portion 103a is not sufficiently long, the predetermined elasticity and bending cannot be obtained, and the base end portion of the movable contact portion 103a is plastically deformed.

Therefore, the height of the switch-equipped connector 100 is determined by the switch terminal 103 which requires a predetermined length, which is higher than the height of general electronic components, so that a portable device equipped with the switch-equipped connector is provided. There is a problem that the entire device such as a telephone becomes large.

The problem that the miniaturization of the switch-equipped connector 100 is restricted by the length of the switch terminal 103 also occurs when the switch-equipped connector 100 is placed horizontally on a printed wiring board as shown in FIG. ,
Since the housing 101 cannot be miniaturized, the projected area of the switch-equipped connector 100 on the printed wiring board becomes large, which causes a reduction in mounting density.

The signal terminal 105a of the plug 105 is also provided.
Needs to be brought into contact with the narrow movable contact portion 103a to be deformed, so that the inner diameter of the plug insertion hole 106 is small.
Probe (plug) by automatic inspection machine as described above
When inserting the plug insertion hole 106 into the plug insertion hole 106, strict positioning accuracy is required between the probe (plug) 105 and the plug insertion hole 106, and the plug insertion hole 10 is accurately inserted.
There was a problem that I could not insert it in 6.

The present invention has been made in order to solve the above problems, and it is possible to reduce the size of the housing and to perform a switch operation even if the plug insertion position is in a relatively wide range. It is intended to provide a connector with a connector.

The switch terminal is provided with a switch terminal leg portion that is electrically connected to the housing and is exposed to the outside of the housing.When the plug is inserted through the plug insertion hole, the movable contact portion of the switch terminal loses contact with the break terminal. In a connector with a switch that contacts a signal terminal of the plug, a housing that covers a plug insertion hole and an upper surface of a contact accommodating chamber. Formed on the cover, the movable contact portion of the switch terminal is composed of a coil spring and a conductive cap attached to the upper end of the coil spring, and is housed in the contact housing chamber so that the conductive cap faces the plug insertion hole. The coil spring causes the conductive cap to elastically contact with the fixed contact portion of the break terminal disposed around the plug insertion hole.

The conductive cap, which is the movable contact portion of the switch terminal, is accommodated in the contact accommodating chamber, and is normally elastically contacted with the fixed contact portion of the break terminal by the elasticity of the coil spring to electrically connect the switch terminal and the break terminal. doing.

Since the plug insertion hole is formed in the cover of the housing which covers the upper surface of the contact accommodating chamber, the plug of the automatic inspection machine or the like can be inserted into the plug insertion hole from above. When the plug is inserted into the plug insertion hole, the conductive cap facing the plug insertion hole is electrically connected by contacting the signal terminal of the plug, and is pressed downward by the plug to contact the break terminal. Be refused.

When the plug is pulled out from the plug insertion hole, the conductive cap returns to its original position again due to the elasticity of the coil spring, and comes into elastic contact with the fixed contact portion of the break terminal.

Since the movable contact portion of the switch terminal does not use a leaf spring piece, a long arrangement space is not required and the housing can be downsized. Also, the shape of the conductive cap can be freely designed without considering the spring characteristics, so that the plate width of the contact part with the plug like the plate spring piece is not restricted, and it can be designed in a wide range. It can be brought into contact with the plug, and the switch operation can be performed at any contact position.

According to another aspect of the connector with a switch of the present invention, the contact accommodating chamber, a housing having a plug insertion hole communicating with the contact accommodating chamber, a fixed contact portion arranged in the contact accommodating chamber, and the housing are exposed to the outside. A break terminal integrally having a break terminal leg portion, a movable contact portion that is in elastic contact with the fixed contact portion of the break terminal at all times in the contact accommodating chamber, and a switch terminal leg that is electrically connected to the movable contact portion and is exposed to the outside of the housing. In the connector with the switch, the movable contact portion of the switch terminal is disconnected from the break terminal when the plug is inserted from the plug insertion hole, and the switch terminal is in contact with the signal terminal of the plug. The plug insertion hole is formed in the cover of the housing that covers the upper surface of the contact storage chamber,
The movable contact portion of the switch terminal is formed of a coil spring, and the coil spring is housed in the contact housing chamber so as to elastically contact with the fixed contact portion of the break terminal arranged around the plug insertion hole, and the tip thereof. The feature is that the part is folded back to face the plug insertion hole.

Connected to.

Since the plug insertion hole is formed in the cover of the housing that covers the upper surface of the contact accommodating chamber, the plug of the automatic inspection machine or the like can be inserted into the plug insertion hole from above. When the plug is inserted into the plug insertion hole, the tip of the coil spring that faces the plug insertion hole is electrically connected by contacting the signal terminal of the plug, and it is pushed downward by the plug to become a break terminal. Contact is cut off.

When the plug is pulled out from the plug insertion hole, the coil spring returns to its original position by its elasticity.
It again makes elastic contact with the fixed contact portion of the break terminal.

Since the movable contact portion of the switch terminal is the coil spring, the housing can be downsized without requiring a long arrangement space unlike the leaf spring piece. Further, since the tip of the coil spring can be bent to freely form the contact portion with the plug, the contact portion with the plug is not limited to the plate width like a leaf spring piece.
It is possible to make contact with the plug in a wide range and to perform the switch operation at any contact position.

In the connector with a switch according to a third aspect of the present invention, in the contact accommodating chamber, a support protrusion is provided so as to project upward from the bottom surface of the housing toward the plug insertion hole, and the base end portion of the coil spring is wound around the support protrusion.

Further, since the support projection is provided so as to project from the bottom surface of the housing toward the plug insertion hole, it functions as a stopper for plug insertion. Therefore, the coil spring does not plastically deform due to the plug entering the contact accommodating chamber more than necessary.

According to a fourth aspect of the present invention, there is provided a switch-equipped connector, wherein the housing comprises a base having a recessed contact accommodating chamber and a cover fitted to the base, and the contact accommodating chamber has a fixed contact portion for a break terminal. After accommodating the movable contact part of the switch terminal, the cover is pinched with the base by the cylindrical ground shell that covers the periphery of the cover, and the cylindrical ground shell is locked to the base to separate the cover and the base. It is characterized by being integrated.

Since the cylindrical ground shell covers the periphery of the cover constituting the housing, it can be brought into contact with the ground terminal of the plug when connecting with the plug.

When the cylindrical ground shell is locked to the base, the base and the cover are integrated with the fixed contact portion of the break terminal and the movable contact portion of the switch terminal housed in the contact housing chamber. It is not necessary to provide a mechanism for retaining the break terminal and the switch terminal from the housing. Further, since the cover is sandwiched between the base and the cylindrical ground shell, the cover can be integrated without providing an engaging mechanism with the base.
