Description

[Detailed description of the invention] [Industrial application field] This invention relates to a conductive connection device, and more specifically, a bent base of a narrow conductive plate, usually called a bus bar, is inserted into a slit provided in a projecting wall of an insulating base. This invention relates to a connection device that prevents bent pieces of a narrow conductive plate from being deformed by external force or accidentally shifting when held together.

[Prior Art] Conventionally, there is a connector housing for making electrically conductive connections as described in, for example, Japanese Utility Model Publication No. 10306/1983.

In this conventional technology, in a connector housing that accommodates a plurality of female bipolar terminals that are provided by fitting one side into a plurality of male terminals arranged in parallel, a connector housing is provided inside a frame body that opens upwardly and downwardly and perpendicularly to the longitudinal side wall. A partition wall is provided to form a plurality of terminal accommodating chambers, and an inclined guide surface is formed on the left and right side walls of the frame body and a lower edge of the partition wall, and the lower end of the partition wall is positioned on the inner and outer sides that do not match the lower opening end of the frame body. This is a connector housing characterized in that the connector housing is located in the

[Problem to be solved by the invention] In the conventional technology described above, the lid body is screwed to the wiring board while the flange formed protruding from the lower part of the housing is pressed down around the hole in a separately prepared lid plate. The housing is attached to the wiring board.

Therefore, it is necessary to separately prepare a cover plate, which is complicated in terms of parts management and increases costs.
The first problem is that it is difficult to work in narrow or dark places because it requires screwing, and a tool such as a screwdriver is required.

In particular, in this conventional example, the base of the rising part (bent piece) of the narrow circuit board cannot be held down by the bottom surface of the housing, and the top surface of the circuit board away from the base is wired at the bottom of the slanted inner surface of the housing's collar. Since it is in pressure contact with the substrate, there is a second problem in that the rising portion is easily deformed or displaced by external force.

In order to eliminate the above-mentioned problems, this invention involves directly inserting the bent base (rising base) of a narrow conductive plate disposed on the insulating base into a slit formed in the protruding wall of the insulating base. By clamping the bent piece to prevent deformation and displacement of the bent piece, and by locking the locking elastic piece of the insulating base to the locking edge of the heat-resistant cylinder,
The purpose is to eliminate the need for a cover plate and its screw fixing.

[Means for Solving the Problems] The object of the invention described above is to provide an insulating base formed of plastic, a guide wall having an upper facing piece provided on the surface of the insulating base, a locking piece, and a projecting wall; It has an elongated narrow conductive plate inserted into a slit formed in the protruding wall, a bent piece formed in the narrow conductive plate, and a through hole through which the bent piece passes, and a locking edge is provided between the guide walls. Each includes a cylindrical body that is locked and attached to the insulating base via a locking bullet, and a male engaging body that includes a female connecting piece that is inserted into the bent piece within the cylindrical body. This is accomplished by holding the base of the bent piece between the protruding walls and the slits.

[Function] By inserting the base of the bent piece of the narrow conductive plate (bus bar) fixedly arranged on the insulating base into the slit formed in the protruding wall of the insulating base, the bent piece is held against the protruding wall. Therefore, the bent piece will not be unnecessarily deformed or displaced due to external force caused by insertion and removal of the female connecting piece.

In addition, the locking wire of the cylindrical body is locked with a single snap of the locking bullet on the insulating base, and it can be mounted and mounted in a so-called "cassette pop" style, especially when the busbar is bent in advance. Automatic mounting is facilitated because the pieces are clamped in their slits on the projecting wall as described above.

[Example] Examples will be described with reference to the drawings.

First of all, the basic structure of this invention is as shown in FIG. 1. Two guide walls 3, 3 having upper facing pieces 2, 2 on the surface of an insulating base 1 made of plastic or the like.
Thus, at least one locking bullet piece 4 is formed.

Then, a second
As shown in the figure, a bent piece 7 formed by bending approximately parallel to each other as shown in FIG. 1 is provided at, for example, an end portion of a narrow conductive plate 6 in the form of an elongated metal strip that is inserted and fixed for use.

The base 7A of the bent piece 7 is inserted into the slit 5a of the projecting wall 5 as described above, and is held between the bent pieces 7 as shown in FIGS. 2 and 5.

Furthermore, a through hole 8 through which the bent piece 7 is passed is formed as shown in FIG. A cylinder 11 made of heat-resistant plastic, such as 66 nylon, is disposed on the insulating base 1 in the state shown in FIG. 5 and then fixed and attached as shown in FIG. 6.

The conductive connection device according to this invention is constituted by each of the male engaging bodies 13 having the above-described features.

In each figure, the part indicated by reference numeral 17 is a locking claw for locking the female connecting piece 12 into the male engaging body 13 as shown in FIG. 6, and the reference numeral 14 is the female connecting piece 1.
2 has an insulated lead-out wire that is conductively connected to the crimped connection part 18 as shown in FIGS. 6 and 7, and 15 and 16 are connected to the cylindrical body 11 and the male connector as shown in FIG. 3, respectively. This is a concave and convex portion formed on the assembly 13 for regulating the insertion direction.

Furthermore, the cylinder 11 may be formed into a cylindrical shape, and the male engaging body 13 may be formed into a hollow columnar shape correspondingly, and the shape of the upper surface of the insulating base 1 and the formation position of the guide walls 3, 3 may be determined.

In addition, an example has been described in which two narrow conductive plates 6 and two bent pieces 7 are provided, but in each case, one each or a plurality of three or more are provided on an insulating base 1.
The number of female connecting pieces 12 and the shape of the male engaging body 13 and the cylindrical body 11 may be selected in accordance with the number of female connecting pieces 12.

Since the conductive connection device of this invention has the above-described configuration, after the narrow conductive plate 6 is separated from the separated state as shown in FIG. 1 and inserted into the slit 5a of the projecting wall 5 as shown in FIG. As shown in FIG. 5, when the cylinder 11 is pushed in from the right side of the insulating base 1 aiming between the lower edges of the upper opposing pieces 2, 2 of the guide rods 3, 3, the locking bullet is released. The piece 10 becomes horizontal while bending against the elasticity due to the pressing stress from the lower surface of the cylinder 11 applied to the upper part of the inclined surface. It snaps into the inner surface of the retaining edge 10 as shown in FIG. 6 and engages elastically, and by one locking, the cylinder 11 is attached to the insulating base 1 as shown in FIGS. 3 and 6. It can be installed in the same way.

At the time of this insertion, the base 7 of the bent piece 7 of the narrow conductive plate 6 (bus bar) fixedly arranged on the insulating base 1
A is inserted in advance into the slit 5a formed in the projecting wall 5 of the insulating base 1 as described above, and the projecting wall 5
Since the cylinder body 11 is held between the cylinders as shown in FIG. 5, installation of the cylinder body 11 can be carried out smoothly, and automatic insertion is also easy.

Even after the above-mentioned insertion, the bent piece 7 remains in the seventh position.
As shown in Fig. 8, the female connecting piece 12 is connected to the cylinder body 1.
It will not be unnecessarily deformed or misaligned due to external force such as when it is inserted or removed within the device.

The narrow conductive plate 6 can be connected to an external circuit via its bent piece 7, female connecting piece 12, and lead wire 14.

This is an example in which the base 7A of the curved piece 7 is inserted and supported within the wide slit 5a.

Next, in the case shown in FIG. 11, the narrow conductive plate 6 placed flat on the insulating base 1 is bent while remaining flat as shown in the figure, and the bent bases of the flat narrow conductive plate 6 and the bent piece 7 are bent. 7A is inserted and supported within the wide and shallow slit 5a of the projecting wall 5.

Further, in the example shown in FIG. 12, a pair of narrow conductive plates 6, 6 are disposed upright on the surface of the insulating base 1, and the narrow conductive plates 6, 6 in the upright state, a bent piece 7
This is an example in which the base 7A is inserted and supported within the narrow slit 5a.

Furthermore, in the example shown in FIG. 13, the narrow conductive plates 6, 6 placed flat on the base body 1 are bent as shown in the figure to make the bent piece 7 stand upright, and its base 7A is supported by a narrow slit 5a. In addition, this is an example in which the narrow conductive plates 6, 6 are inserted and supported in the wide slit 5a.

In these other embodiments, parts designated by the same reference numerals as in the basic embodiment indicate parts having the same effect.

Further, the locking bullet piece 4 is connected to the front part of the insulating base 1 and the cylinder body 1.
If a gap is provided between the bottom surface of the cylindrical body 11 and the bottom surface of the insulating base 1, the cylindrical body 11 can be removed from the insulating base 1 by pushing down the locking bullet piece from the front side of the gap with a screwdriver, etc. against its elasticity.
