Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an output terminal structure of an electromagnetic switch that is housed in a recess formed between the positive and negative terminals of a battery.

(Prior Art) As a conventional electromagnetic switch of this type, one described in Japanese Patent Application Laid-open No. 62-93828 has been proposed, but in this case, the electromagnetic switch has a bottomless box-shaped housing. The electromagnetic switch is housed in the housing from its bottom opening side, and both terminal portions constituting the fixed contacts of the electromagnetic switch are provided above and on the sides of the housing.

(Problems to be solved by the invention) However, in such a conventional terminal structure,
Each terminal part is located above and on the side of the housing,
Moreover, since the structure protrudes to the outside of the housing, the outer shell of the battery protrudes outward by the protrusion, and if the entire battery is housed in a single case, the case must be enlarged. However, there was a problem in that there was a natural limit to the reduction of the installation space.

Therefore, in order to solve this problem, if the terminal section is simply provided adjacent to the pole terminal of the battery, if the terminal section is an output terminal section that does not require electrical connection with the pole terminal, both Not only will interference occur in the layout and configuration, but if you try to forcibly fasten another terminal member for connecting the load circuit to the output terminal in such a state, it will cause problems in connection work, and
This has the disadvantage that it is unfavorable in terms of circuit operation.

(Means for Solving the Problems) This invention was made to solve the problems of the prior art, and in an electromagnetic switch housed in a recess formed between the positive and negative terminals of a battery, The housing of the electromagnetic switch body is formed into a substantially rectangular cylindrical shape, the electromagnetic switch body is housed inside the housing along the longitudinal direction, and the battery side connection terminal extends and connects to the battery positive terminal, and the load an output terminal portion connected to the circuit extending along the longitudinal direction of the housing;
The electrically disconnected connection part of the battery negative terminal provided at the end of the housing and the adjacent stepped part (fixed part)
The end of the output terminal portion and the terminal member on the load side are overlapped and fastened together, and the switch main body can be stored within the outer shell of the battery.
While minimizing the overall size of the switch and avoiding expansion of installation space, it also avoids interference between the output terminal of the electromagnetic switch and the terminal of the battery adjacent to the output terminal, facilitating connection work and improving circuit operation. The present invention provides an output terminal structure of an electromagnetic switch that makes it possible to eliminate interference.

(Function) Since the main body of the electromagnetic switch is housed in a substantially rectangular cylindrical housing, both terminals that make up the fixed contacts of the electromagnetic switch are located at both open ends of the housing, while the output terminal For example, a thick stepped portion may be formed in the housing adjacent to the terminal of the battery that does not require electrical connection with one of the terminal portions of the battery. In addition, the load circuit can be easily fixed together with the terminal member to which the load circuit is to be connected.

(Example) Figures 1 to 5 show the case where the present invention is applied to an electromagnetic switch 2 that is directly attached above a battery 1 (on the protruding side of the positive and negative terminals 1A and 1B). The main body of the electromagnetic switch 2 consists of a solenoid section 4 and a fuse mounting section 5 housed in a horizontally elongated, substantially rectangular cylindrical housing 3.

The excitation coil 6 of the solenoid section 4 is covered with a solenoid case 7 having a substantially U-shaped cross section, and the electromagnetic force acting between the excitation coil 6 and the excitation coil 6 causes the plunger 8 to move in the left-right direction in FIG. The return spring 30 attached to the plunger 8 has a biasing force larger than that of the spring 10 attached to the contact 9 except when the excitation coil 6 is energized. Plunger 8 connects contact 9 to spring 1
It is designed to move forward (move to the left in FIG. 1) against a biasing force of 0.

The excitation coil 6 is energized via the connecting wires 25, 26 and the lead wire 6a (only the one located on the near side is shown by imaginary lines in FIG. 1), as will be described later.

On the other hand, the fuse mounting portion 5 is covered by a removable cover 5.
On the other hand, it has a rectangular hole-shaped mounting recess 12 formed in the casing 11, and a removable fuse guide 13 is inserted into this mounting recess 12. The blade 15 (only one of which is shown in FIG. 1) of the blade fuse 14 is fitted into a branch connection terminal 24, which will be described later, in a press-fit state.

On the other hand, the lower end side of the casing 11 and the housing 3
A battery-side terminal plate 16 bent into a crank shape is sandwiched between the battery-side terminal plate 16 and a battery-side terminal plate 16 bent into a substantially L-shape above the solenoid portion 4. A component load-side terminal plate 17 is arranged, and the load-side terminal plate 17 and the battery-side terminal plate 16 described above are electrically connected to and separated from each other by contacts 9.

Here, one end of the battery side terminal plate 16 (the left end in FIG. 1) is connected to the opening 3A at one end of the housing 3.
It extends to the side and is connected to the positive terminal 1A of the battery 1 via the bolt 18 (see Figure 3), and the other end (the left end in Figure 1) extends to the contact 9 position described above. ing. On the other hand, one end (the left end in FIG. 1) of the load-side terminal plate 17 is at the contact 9 position, and the other end (the right end in FIG. 1) passes through the opening 3B of the housing 3 and the other end (the left end in FIG. It extends to a thick fixing portion 3F formed at the right end in FIG.
A fixing hole 3H is formed in this fixing part 3F, and a substantially L-shaped relay terminal plate 19 is attached to the position where this fixing hole 3H is formed (see Fig. 2). The load-side terminal plate 17 and the relay terminal plate 19 are fastened together by a bolt 20 screwed into a first bolt hole 19h as a fastening portion formed in the relay terminal plate 19. Note that this relay terminal plate 19 has a first bolt hole 19.
A second bolt hole 19p is formed as another fastening portion having a center direction perpendicular to the center direction of h.

On the other hand, the negative terminal 1B of the battery 1 is attached to a bolt 22 ( (see FIG. 5). In other words, there is no need for electrical connection between the auxiliary terminal board 21 and the load-side terminal board 17. Here, the connecting portion 3S is formed thinner than the above-described fixing portion 3F, and has a predetermined step d. Note that a grounding wire (not shown) for grounding the negative electrode of the battery 1, for example, is connected to the auxiliary terminal board 21.

In addition, the battery side terminal plate 16 is connected to the positive terminal 1A of the battery 1 as described above, and is connected to the first terminal, which is the main switch circuit, via the branch connection terminal 24 and the blade fuse 14 branched from the approximately intermediate position. While connected to a load circuit (not shown), the load side terminal board 17 is connected to a second load circuit (not shown). Here, connecting wires 25 and 2 for energizing the excitation coil 6 are connected.
6 and the connecting wire 27 for supplying current from the blade fuse 14 to the first load circuit are tied together.
It is designed to be installed on 1.

Therefore, the electromagnetic switch 2 is adapted to supply current from the battery 1 to the first and second load circuits, for example, to operate the first load circuit (for example, to operate the starter switch in the load circuit). When the excitation coil 6 is energized via the battery side terminal plate 16, the branch connection terminal 24, and the blade fuse 14 due to the ON operation), the plunger 8 retreats against the biasing force of the return spring 30, and the contact 9 closes to the battery side. The side terminal plate 16 and the load side terminal plate 17 are electrically connected, and a second load circuit (for example, a starter motor) is operated via the load side terminal plate 17.

In this case, the connection terminals for the second load circuit may be connected together with the bolts 20, but in cases where connection work is difficult, etc., the connection terminals for the second load circuit may be tightened together using the second bolt holes 19p. other bolt 3
1 (see FIG. 2, FIG. 4, FIG. 5, etc.), and the extending direction of the connection may be changed.

In addition, the fixed part 3F and the connecting part 3S adjacent to this
Since a predetermined step d is formed between the load-side terminal board 17 and the auxiliary terminal board 21, interference between the load-side terminal board 17 and the auxiliary terminal board 21 or between the connection cords or connection cables does not occur.

Incidentally, the electromagnetic switch 2 configured in this way is installed in a recess 1D formed between the two pole terminals 1A and 1B of the battery 1, and the main body of the electromagnetic switch is attached to a rectangular cylindrical housing 3. Moreover, each terminal portion is located at both ends along the longitudinal direction of the housing 3.

In addition, as shown in this embodiment, when an L-shaped relay terminal board is provided at the fixing part of the housing that fixes the end of the terminal part, the connection direction can be selected, so that the end part of the terminal part can be connected to the terminal part. This has the effect of increasing the degree of freedom in connection of the load circuit.

(Effects of the invention) As described above, according to this invention, the switch body is housed in a substantially rectangular cylindrical housing, and a thick step is formed at the end of the housing, and an electromagnetic switch is attached to this fixed part. Since the end of the terminal part constituting the fixed contact is fixed together with other terminal members, there is no need for structural and electrical connection with the terminal that is adjacent to the stepped part and does not require electrical connection with the terminal part. This avoids physical interference, making connection work easier and preventing problems with circuit operation at the same time.

In addition, if an L-shaped relay terminal board is provided on the stepped part of the housing that fixes the end of the terminal, the connection direction can be selected, increasing the degree of freedom in connecting the load circuit connected to the terminal. It has the effect of increasing
