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 above-mentioned invention is to provide an insulating base formed of plastic, a locking protrusion, a locking edge, and a projecting wall provided on the surface of the insulating base, and the projecting wall. An elongated narrow conductive plate inserted into the formed slit, a bent piece formed on the narrow conductive plate, a through hole through which the bent piece passes, and a side piece that engages with the locking protrusion, and A male engaging body comprising: a cylindrical body that is latched and attached to the insulating base via the latching edge with a latching bullet; and a female connecting piece that is inserted into the bent piece within the cylindrical body. This is achieved by sandwiching the base of the bent piece between the projecting wall and the slit.

[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 bullet of the cylinder locks into the locking edge of the insulating base with a single snap, and it can be mounted in a so-called "cassette-pon" style. Especially when this is mounted, the bent piece of the bus bar is fixed as described above. Since it is clamped in advance on the projecting wall within its slit, automatic mounting becomes easy.

Furthermore, during this mounting, the upper surface of another bus bar embedded in the upper surface of the insulating base can be covered and protected by the lower surface of the cylinder.

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

As shown in FIG. 5, first, from the right side of the insulating base 1, aim between the hooks of the locking protrusions 3 and push in while applying the side pieces 9 of the cylinder 11, the locking pieces will be released. 10 becomes horizontal while bending against the elasticity due to the pressing stress from the upper surface of the insulating base 1 applied to the lower part of the inclined surface, and then the locking bullet piece 1
Due to its elasticity, the end face of the cylindrical body 11 snaps into the inner surface of the locking edge 4 of the insulating base 1 as shown in FIG. As shown in FIG. 6 and FIG. 6, it can be mounted in a so-called "cassette pop" style.

If you look at the locking protrusion 3 from the front of the insulating base 1 and push it in while applying the side piece 9 of the cylinder 11,
The locking bullet piece 10 becomes horizontal while bending against the elasticity due to the pressing stress exerted by the upper surface of the insulating base 1 on its lower inclined surface, and then the end surface of the locking bullet piece 10 becomes horizontal when the end surface of the locking bullet piece 10 is pressed against the upper surface of the insulating base 1. It snaps into the inner surface of the retaining edge 4 and engages elastically, allowing the cylinder 11 to be attached to the insulating base 1 in a so-called "cassette pop" manner by one-shot locking.
