Abstract

PROBLEM TO BE SOLVED: To make prevention of mutual contact of short-circuit members compatible with flexibility of short-circuit pattern. SOLUTION: A plurality of receiving grooves are formed in a terminal 20 with a space left therebetween in the direction crossing short-circuit plates 25. Because the short-circuit plates 25 each fitted in different receiving grooves are disposed with a space left between each other in the direction crossing the direction of length of the short-circuit plate 25, there is no fear that the short-circuit plates 25 make contact with each other differently from the case where the plurality of short-circuit plates are arranged side by side in a line. Moreover, because there is no need to provide a partition wall such as to divide a mounting area of the short-circuit plates 25 into sections, it is possible to mount the short-circuit plates 25 of arbitrary lengths in arbitrary positions.

The terminals 3 are fitted into the receiving groove 6 formed so that the terminals 3 are short-circuited via the short-circuit plate 5.

In this joint connector, by using a plurality of short-circuit plates 5, it is possible to divide a group of terminals that are short-circuited into a plurality of terminals. In this case, as shown in FIG. 6, the plurality of short-circuit plates 5 have one mounting groove 4
Short-circuit plates 5 that are arranged in a horizontal line inside and adjacent to each other
The ends are attached to each other so as to be in non-contact with each other in the partition wall 7 between the cavities 2.

[0004]

However, since the gap between the short-circuit plates 5 adjacent to each other can be ensured only by the thickness of the partition wall 7 between the cavities 2, the ends of both the short-circuit plates 5 are extremely close to each other. Inevitably, both short-circuit plates 5 may come into contact with each other.

Therefore, as a countermeasure against this, a partition wall 8 is provided in the mounting groove 4 so as to be located between the adjacent short-circuit plates 5. However, when the partition wall 8 is formed, the mounting groove 4 is divided in the length direction, so that the short circuit pattern is limited. Therefore, in order to cope with a plurality of types of short-circuit patterns, a dedicated connector housing must be molded for each short-circuit pattern, resulting in an increase in die cost.

The present invention was devised in view of the above circumstances, and it is an object of the present invention to prevent both short-circuit plates from contacting each other and ensure the degree of freedom in setting a short-circuit pattern. is there.

According to the invention of claim 1, 1
When the terminal group short-circuited by one short-circuit member is divided into a plurality of terminals, the short-circuit member is fitted in the receiving groove different for each terminal group. The short-circuit members of different terminal groups are arranged at intervals in the direction intersecting with the short-circuit members. Therefore, there is no fear that the ends of the short-circuit members will contact each other as in the case where a plurality of short-circuit members are mounted in a case where all the receiving grooves are arranged in a line. Moreover, since it is not necessary to provide a partition wall that divides the mounting area of the short-circuit member to prevent contact, it is possible to mount the short-circuit member of any length at any position. As described above, according to the present invention, it is possible to prevent both the short-circuit members from contacting each other and ensure the degree of freedom in setting the short-circuit pattern.

According to the second aspect of the present invention, terminals having receiving grooves formed at the same positions are selected as terminals to be short-circuited with each other, and when these are mounted on the connector housing, the receiving grooves are positioned on a horizontal line. To do so. When dividing the terminal group to be short-circuited into multiple,
Different types of terminals are used for each terminal group. Then, when the short-circuit member is fitted into the plurality of receiving grooves arranged in a line on the horizontal line, the terminals to which the short-circuit member is fitted are short-circuited to each other. The short-circuit members of different terminal groups are arranged at intervals in the direction intersecting with the short-circuit members. Therefore, there is no fear that the ends of the short-circuit members will contact each other as in the case where a plurality of short-circuit members are mounted in a case where all the receiving grooves are arranged in a line. Moreover, since it is not necessary to provide a partition wall that divides the mounting area of the short-circuit member to prevent contact, it is possible to mount the short-circuit member of any length at any position. As described above, according to the present invention, it is possible to prevent both the short-circuit members from contacting each other and ensure the degree of freedom in setting the short-circuit pattern.

BEST MODE FOR CARRYING OUT THE INVENTION

<First Embodiment> Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. The connector housing 10 has a plurality of chambers elongated in the front-rear direction (in this embodiment, 1
The cavities 11 of 0 chambers are formed side by side in the left-right direction. Adjacent cavities 11 are separated from each other by partition walls 12. The rear end of each cavity 11 is an insertion opening 13 that opens to the rear end surface of the connector housing 10. The terminal 20 fixed to the end of the electric wire W is inserted through the insertion opening 13 so that the inside of the cavity 11 is closed. Housed in. The terminal 20 inserted into the cavity 11 at a predetermined position has its front end face abutted against the back end face of the cavity 11 and the locking hole 2 on the bottom face.
1 is locked to the elastic locking piece 14, whereby all the terminals 20 are held in the movement-restricted state at a fixed position in the insertion / removal direction.

The connector housing 10 is provided with two mounting grooves 15 which are open on the upper surface of the front end portion thereof. These mounting grooves 15 extend in parallel with each other over the entire width of the connector housing 10 along the left-right direction (direction orthogonal to the insertion direction of the terminal 20), and have a predetermined interval in the insertion direction of the terminal 20. It is arranged in two positions with a space between. The mounting groove 15 is formed so as to penetrate the upper surface plate portion of the connector housing 10 and open to the ceiling surface inside the cavity 11, and to vertically cut out the upper region of the partition wall 12. The cutout portion 15 of the partition wall 12 is formed.
The adjacent cavities 11 are communicated with each other by A. A short-circuit plate (a short-circuit member, which is a constituent of the present invention) 25 described below is attached to each of the two mounting grooves 15 so as to cross the cavity 11 and the terminal 20. At the opening edge of the mounting groove 15 to the upper surface of the connector housing 10, a tapered guide surface 16 for preparing the mounting of the short circuit plate 25 is provided.
Are formed. Only one type of connector housing 10 having the above structure is prepared.

On the other hand, the terminal 20 to be inserted into the cavity 11 is formed with two receiving grooves 22 so as to cut out the upper regions of the upper surface and the left and right side surfaces.
Both of the receiving grooves 22 are formed in the cavity 11 and the terminal 20.
In the inserted state, the two mounting grooves 15 are aligned at the same time. When the short-circuit plate 25 is attached to the mounting groove 15 in which the receiving groove 22 is aligned, the lower end of the short-circuit plate 25 fits into the receiving groove 22 and the short-circuit plate 25 and the terminal 20 are brought into a conductive state. The terminal 20 having the above-described configuration is the connector housing 1
As with 0, only one type is available.

Next, the operation of the present embodiment will be described. In the present embodiment, a case will be described in which the six terminals 20 are divided into two terminal groups, and the terminal groups are short-circuited by different short-circuit plates 25. First, regarding the terminal 20 accommodated in the cavities 11 of the upper three chambers in FIG. 3, by fitting the short-circuit plate 25 in the front receiving groove 22, the
The terminals 20 are short-circuited to each other. On the other hand, the lower three terminals 20 in the figure are short-circuited with each other by fitting another short-circuit plate 25 into the rear receiving groove 22.

In this state, the two short-circuit plates 2
Since the five terminals are arranged with a large gap in the direction orthogonal to the direction traversing the terminal 20, the short-circuit plates 25 do not come into contact with each other. The edge of the short-circuit plate 25 corresponds to the side surface of the terminal 20 of the other short-circuit circuit through the cutout portion 15A in the partition wall 12 of the mounting groove 15, but the distance between the short-circuit plate 25 and the terminal 20 is This is large compared to the facing distance when the edges of the two short-circuit members face each other in the thickness region of the partition wall as in the prior art. Therefore, the edge of the short-circuit plate 25 and the terminal 2
There is no risk of contact with the 0 side surface.

Further, as described above, as a means for preventing the short-circuit plates 25 from contacting each other, the short-circuit plates 25 are arranged in a state in which they are widely separated in the direction orthogonal to the direction traversing the terminal 20, so that mounting is possible. The groove 15 does not need to be provided with a partition that divides the groove 15 in the lengthwise direction. Therefore, it is possible to mount the short-circuit plate 25 having an arbitrary length in each mounting groove 15 in accordance with the short-circuit pattern over an arbitrary region, and the degree of freedom in setting the short-circuit pattern is high.

As described above, according to this embodiment, it is possible to prevent both the short-circuit plates 25 from contacting each other and ensure the degree of freedom in setting the short-circuit pattern. Moreover, the connector housing 10
Since only one type of terminal 20 needs to be prepared, the cost is kept low as compared with the case of preparing a plurality of types. <Embodiment 2> Next, Embodiment 2 of the present invention will be described with reference to FIG. In this embodiment, the configuration of the terminal is different from that of the first embodiment. Other configurations are the same as those of the first embodiment, and thus the same configurations are denoted by the same reference numerals, and
The description of the action and effect is omitted.

In this embodiment, two types of terminals 30 are used.
F and 30R are prepared. Both terminals 30F, 3
The receiving groove 22 is formed in each 0R. The receiving groove 22 of the terminal 30F of one type is arranged at a position corresponding to the mounting groove 15 on the front side of the connector housing 10,
The receiving groove 22 of the other type of terminal 30R is arranged at a position corresponding to the mounting groove 15 on the rear side. When fixing the terminals 30F and 30R to the electric wire W, the same type of terminal 30F or 30R is applied to the electric wire W to be short-circuited.
To be fixed. Then, the terminals 30F or 30R of the same type are mounted in the connector housing 10 so as to be continuously arranged side by side. Then 1
Regarding one terminal group, the receiving grooves 22 are arranged side by side in a line corresponding to the front mounting groove 15, and the receiving grooves 22 of the other terminal groups are arranged horizontally in a position corresponding to the rear mounting groove 15. Since they are lined up on a line, if a separate short-circuit plate 25 is fitted to each of the receiving grooves 22 lined up on a horizontal line, each terminal group is short-circuited.
