The interrupt coupler 10 is also configured to enable interrupt connection of up to two circuits, has an interrupt terminal 11 and a holder 12, and is formed separately from the main body 2.

The interrupt terminal 11 is electrically connected to the interrupt line 14 by caulking and fixing a conducting wire 15 extending from one end of the interrupt line 14 at a caulking portion 13 at one end, as shown in part A of FIG. ing.

The interrupt terminal 11 is formed in two stages by connecting a horizontal portion 16 extending from the crimped portion 13 and a tip portion 17 with an oblique portion 18, and is engaged in the vicinity of the crimped portion 13 of the horizontal portion 16. A hole 19 is formed.

6 is formed, and a pawl 27 capable of engaging with the engaging recess 8 is provided at the tip of each engaging arm 26.

The cover 21 is turned over while bending the resin hinge 22, and is overlapped with the base 20, so that the pair of ribs 23 are fitted into the recesses 25 and integrated to form the holder 12. There is.

FIG. 2 is a cross section in the coupling direction of the main coupler 1 and the interrupt coupler 10 in the interrupted connection state, and FIG. 3 is a cross section taken along line 3-3 of FIG. 2 (the main coupler side is schematically represented). .

As is apparent from these figures, the main coupler 1 is a female type, and the female type main terminal 31 connected to the main line 30 has a cylindrical portion 32 at the tip thereof, and a protruding end therein. A spring portion 33 formed by folding back is provided.

The tip portion 17 of the interrupt terminal 11 is inserted between the spring portion 33 and the horizontal portion 34 of the main terminal 31. The horizontal portion 34 is prevented from coming off by engaging a retaining projection 37 formed on a supporting wall 36 on the case side with an engaging hole 35 thereof. Reference numeral 38 is a crimped portion of the main terminal 31, and 39 is a conducting wire of the main line 30.

The male main coupler 40, which is connected to the main coupler 1 shown in phantom in FIG. 2, is connected to the male main terminal 4 at the time of connection.

Next, the operation of this embodiment will be described. In FIG. 1, first, as shown in part A, the holder 1
The two base portions 20 and the cover portion 21 are separated from each other, the interrupt terminal 11 is inserted between both members, and the caulked portion 13 is sandwiched between the pair of ribs 23 provided on the base portion 20.

Subsequently, the cover portion 2 inverted from above
1 and the caulking portion 13 and the pair of ribs 23 are fitted into the concave portion 25 of the cover portion 21, the integrated holder 12
The interrupt coupler 10 sandwiching the interrupt terminal 11 is assembled.

To interrupt-connect the interrupt coupler 10, the slit 5 of the main coupler 1 in which the terminal lock 3 has been removed by cutting the resin hinge 4 in advance.
Insert the tip portion 17 of the interrupt terminal into the cylindrical portion 32 of the main terminal 31.

At the same time, the holder 12 is placed on the stepped portion 2b, the engaging arm 26 is moved along the side surface 2c of the case, and the holder 12 is further pushed into the main body 2 side.
Engages with the engaging recess 8 and the interrupt coupler 10 is integrated with the main coupler 1.

As a result, the tip portion 1 of the interrupt terminal 11 is
Since 7 contacts the horizontal portion 34 of the main terminal 31 and becomes conductive, the interrupt connection is completed.

In this state, when the main coupler 40 on the mating side is coupled to the main coupler 1, the main terminal 41 pushes down the spring portion 33, so that the tip portion of the spring portion 33 causes the tip portion of the interrupt terminal 11. 17 is a horizontal portion 34 of the main terminal 31
It is pressed to the side.

Therefore, the interrupt terminal 11 is more reliably connected to the main terminal 31. In this embodiment, since the spring portion 33 is pressed, the tip portion 17 of the interrupt terminal 11 does not necessarily have to contact the horizontal portion 34 side and may be in a floating state. In either case, the structure is such that connection failure is unlikely to occur.

Further, since only one interrupt coupler 10 is required and only one main coupler 1 is required to be interrupted, the number of parts can be reduced, the space for interrupt can be reduced, and the cost can be reduced.

Moreover, since the interrupt coupler 10 can be easily attached to the main coupler 1 by utilizing the engaging recess 8 of the terminal lock 3, the interrupt coupler 10 can be easily attached.

In addition, the existing main coupler 1 can be processed only by removing the terminal lock 3, and the slit 5 can be commonly used as the slit 5 which is previously formed for the terminal lock 3. Minimal work is required.

Further, the interrupt coupler 10 has a base 20.
Since it can be assembled only by sandwiching the interrupt terminal 11 with the cover portion 21, the structure is simple and the assembly is easy.

The present invention is not limited to the above-mentioned embodiment and can be applied in various ways. For example, the main coupler may be either male type or female type. Further, either one circuit or multiple circuits of two or more circuits is possible, and accordingly, the number of main terminals is appropriately provided to be from a single number to a large number and in a single stage or multiple stages.

The number of interrupt terminals of the interrupt coupler can be set to any number as needed, and when interrupting a small number of interrupt terminals to a main coupler having a large number of terminals, it is sufficient to interrupt only a part of the terminals of the main coupler. .

Further, as the engaging structure of the interrupt coupler with respect to the main coupler, the terminal lock may be commonly used or may be separately formed.

Similarly, the terminal lock of the main coupler is not always removed, and there are cases where the interrupt connection can be made even when the main coupler is attached. Further, it is possible to provide a slit at a place different from the place where the terminal lock is attached and attach the interrupt coupler.
