Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a conductive connecting device, more specifically, a bent base portion of a narrow conductive plate, which is usually called a bus bar, is provided with a through hole of a bottomed insulating cylinder and a peripheral lower surface thereof. And a connection device which is tightly sandwiched between the surface of the insulating base and the bent piece of the small-width conductive plate that is not deformed by an external force or is not displaced indefinitely.

[Prior Art] As a connector housing for making a conductive connection, there is a connector housing disclosed in, for example, Japanese Utility Model Publication No. 58-10306.

In this conventional technique, a connector housing for accommodating a plurality of female bipolar terminals provided by fitting one side to a plurality of juxtaposed male terminals is provided, and a longitudinal side wall and A plurality of terminal accommodating chambers are formed by providing orthogonal partition walls, and inclined guide surfaces are formed on the left and right side walls of the frame and the lower edge of the partition wall, and the lower end of the partition wall does not match the lower opening end of the frame body. The connector housing is characterized in that it is located on the outer side.

[Problems to be Solved by the Invention] In the above-mentioned conventional technique, the lid plate is screwed to the wiring board in a state where the brim formed by projecting on the lower part of the housing is pressed around the hole of the separately prepared lid plate. The housing is attached to the wiring board.

Therefore, it is necessary to prepare a lid plate separately, which is complicated and costly in terms of parts management, and it is difficult to work in narrow places and dark places because it requires screwing, and tools such as a screwdriver are required. The first problem is that it is necessary.

In particular, in this conventional example, the rising portion (folded piece) of a narrow circuit board
Since the base itself cannot be pressed by the lower surface of the housing, and the upper surface of the circuit board that is away from the base is pressed against the wiring board at the lower part of the inclined inner surface of the collar of the housing, the above-mentioned rising portion is deformed by external force. Or second position that is easily displaced
There was a problem.

In addition to this, as described in Japanese Utility Model Laid-Open No. 58-109184, there is also one in which the periphery of a connection terminal which is installed upright by means such as crimping on a conductive printed portion of a printed wiring board is surrounded by a terminal guide adapter. However, this is a work in which the printed surface and the terminals are crimped or soldered, and the workability is poor. Moreover, as shown in FIGS. 2 and 3 of the drawings of the above publication, the base of the essential connecting terminal is in the hole of the adapter. There is a problem that it cannot be reinforced because it is simply inserted and not sandwiched between the lower surface of the adapter and the upper surface of the print hard board.

Further, there is a type in which the end portion of a small-width conductive plate is just erected as in Japanese Utility Model Laid-Open No. 55-160087, but in this type, when the connector is attached or detached, the connection pin or the connection terminal is easily twisted and deformed. There is.

Even if the above two are combined, there is a problem that, like the above-mentioned problem, a gap is generated between the lower surface of the adapter and the upper surface of the conductive plate, so that the bent piece base cannot be sandwiched and the reinforcement cannot be performed.

In order to eliminate the above-mentioned problems, the present invention has a bent piece insertion hole of a bottomed cylinder in which a bent piece base (a rising base) of a narrow conductive plate disposed on an insulating base is directly made of an insulating material. It is intended to prevent the bent piece from being deformed and its position from being displaced by press-contacting the surface of the insulating substrate with the peripheral lower surface thereof.

[Means for Solving the Problems] The above-mentioned object of the present invention is to provide an insulating base made of plastic or the like, and a locking projection provided on the upper surface of the insulating base.
At least one locking edge, a projecting wall projecting from the rear upper surface of the base, a narrow narrow conductive plate disposed on the insulating base along one surface of the projecting wall, and the narrow conductive plate. An insulative base body is formed in which a bent piece formed in parallel, a through hole through which the bent piece passes, and a side piece that engages with the locking projection are respectively formed, and the locking bullet piece is locked to the locking edge. And a male engaging body having a female connecting piece inserted into the bending piece in the bottomed cylindrical body. This is achieved by sandwiching and reinforcing the base portion of the piece with the outer peripheral surface of the through hole of the bottomed cylindrical body and the surface of the projecting wall.

[Operation] Small-width conductive plate (bus bar) fixedly mounted on the insulating base
The base of the bent piece can be tightly clamped between the bottom surface of the bottom of the bottomed cylindrical body attached to the insulating base body with the locking bullet piece and the upper surface of the base body. It will not be deformed or displaced due to external force due to such factors.

Further, the bottomed cylindrical body can be attached and mounted in a so-called "cassette pon" type by engaging the snap bullets with a snap and without using a cover plate or a tool on the edge of the base body.

Further, in this mounting, the upper surface of another bus bar embedded in the upper surface of the insulating substrate can be covered with the lower surface of the bottomed cylindrical body.
