[Problems to be Solved by the Invention] In the above-mentioned conventional technique, when connecting a fuse or a bracket of a straight tube lamp to another conductive member, a lead wire or the like is soldered to the fuse bracket or connected, A strip-shaped narrow conductive plate called a bus bar is connected by caulking.

Therefore, in this conventional technique, in addition to the problem that a connecting tool such as a soldering iron or a crimping tool is required, the above-mentioned connecting work is troublesome, and it is not possible to connect particularly in a narrow place or a dark place such as an engine room of an automobile. There was a problem.

In addition to this problem, in order to install fuses and straight tube lamp brackets on conductive plates such as the body and chassis, it is necessary to interpose one special insulating bush on each fuse and straight tube lamp bracket. Because it was complicated, workability was poor.

In addition, the fuses and straight tube lamp brackets generate heat at their contact parts due to the electric current, so there were many problems that the entire fuse box had to be made of expensive heat-resistant plastic such as 66 nylon.

In order to eliminate the above-mentioned problems, the present invention makes it possible to easily and reliably connect another conductive member to a hugging socket type connector without using a connecting tool, and the assembled structure of the connector. The object is to be able to attach the body with good compatibility to any place regardless of conductive or non-conductive member.

[Means for Solving the Problems] The above-described object of the present invention is to provide an insulating base body formed of an insulating material into a substantially rectangular parallelepiped frame shape, and a plurality of locking hook pieces and brim pieces projecting from the side surface of the insulating base body. A pair of connector insertion holes formed in the insulating base body, a pair of projections projecting from opposing surfaces of the connection device insertion holes, and a pair of clamping pieces formed by molding an elastic conductive plate into a substantially shape. Two connecting tools each provided with a lead wire, and a mounting hole formed in the base of the sandwiching piece of these two connecting tools, through the projections forming the pair, respectively into the unpaired connecting tool insertion hole. And a mounted member assembly having mounting holes that are slightly larger than the planar contour of the insulating base and having escape holes formed at positions facing the locking hook pieces. Attach the connector assembly to the attached body using the attachment holes with the locking hook piece and the flange piece. It is achieved by wearing.

[Operation] By providing a pair of holding pieces and a lead wire in one connecting tool, a straight tube lamp, a glass tube fuse, etc. can be held and held tightly by a pair of holding pieces.

Since the connector mounting structure, that is, the connector assembled structure is surrounded by the insulating base, the two connecting tools can be mounted through the base with good compatibility regardless of whether they are conductive plates or insulating plates.

Then, the connector assembly 9 is attached to the locking hook pieces 2a, 2a and the flange piece 2
b and 2b are attached to the mounted body 12 through the mounting holes 10 as shown in FIGS. 3 and 6 after the state shown in FIGS.

Next, a specific example of the attachment structure of the connector according to the present invention will be described in detail.

The insulator 1 is formed by molding a heat-resistant plastic such as 66 nylon or polybutylene terephthalate, as shown in FIG. , 3 are formed, the insertion hole 3 is opened on the lower surface side of the base body 1 as shown in the figure, and a pair of protrusions 4, 4 for locking the connector 7 are provided on the inner wall surfaces facing each other. It is provided.

As shown in FIG. 1, the connecting tool 7 is made of a conductive leaf spring material, such as phosphor bronze, nickel silver, beryllium copper, etc., which is punched out in a letter-like shape so that the bottom portion is formed at the branch portion. A pair of sandwiching pieces 5 and 5 serving as a hugging socket portion are formed by bending in a substantially letter shape, and the lead wire connecting portion 6 extending from the side of the bottom is parallel to the pair of sandwiching pieces 5 and 5, for example. Is bent and formed.

The lead wire connecting portion 6 may be a simple protruding piece, or may be the lead wire connecting portion 6 in which the lead wire 6a is soldered or caulked to the bottom portion between the sandwiching pieces 5, 5.

At the bases of the holding pieces 5 and 5 described above, the projections 4 and 4 of the connector insertion hole 3 are provided.
A rib for forming a chimney effect for heat dissipation by forming a gap between the mounting holes 8 and 8 which are engaged and locked with each other, the reinforcement of the holding pieces 5 and 5 and the inner wall of the connector insertion hole 3 18,18 are formed.

As shown in FIG. 2, the connector 7 is a pair of holding pieces.
The protrusions 4, 4 are provided with mounting holes 8, 8 formed at the bases of 5, 5 on the wall surfaces of the connector insertion hole 3 of the insulating base 1 facing each other.
Using the elasticity of the sandwiching pieces 5 and 5, the connector assembly 9 is made by fitting and snapping together.

The attached body 12 is made of a plastic or metal plate and has an attachment hole 10 which is slightly larger than the plane contour of the insulating base 1 as shown in FIG. Relief holes 11 and 11 are formed at the positions facing 2a.

As shown in FIG. 3, the connector assembly 9 is attached to the attachment hole 10 of the attached body 12 by the locking hook pieces 2a, 2a and the collar pieces 2b, 2b as shown in FIGS. 4 to 6. Insert and mount in the order shown.

That is, in this case, as shown in FIG. 5, the edge of the attachment hole 10 of the attached body 12 is spread out in the direction in which the escape hole 11 becomes narrower against its elasticity by the slope of the locking hook piece 2a of the insulating base 1. The so-called "cassette pon" by being snapped and locked by one shot
Can be easily attached to the formula.

In this mounted state, the vertical movement of the insulating substrate 1 with respect to the mounted body 12 causes the hook edge of the locking hook piece 2a and the upper surface of the brim piece 2b to contact the upper and lower surfaces of the mounted body 12, respectively. Because it is regulated, there is no rattling.

Further, the horizontal movement of the insulating substrate 1 is restricted by the periphery of the attachment hole 10 of the mounted body 12 and does not rattle.

If the mounted body 12 is made of metal, its relief hole 11
The wall width between the attachment hole 10 and the attachment hole 10 may be formed small.

In addition, connecting conductive parts 1, 1 such as a straight tube lamp L and a glass tube fuse are inserted and used between the pair of holding pieces 5, 5.

Further, FIGS. 7 to 11 show another embodiment of the present invention, in which the edge of the attachment hole 10 of the mounted body 12 is raised to form a frame shape and the lower surface of the insulating base 1 in the mounted state. And attached body
The lower surface of 12 is made flush as shown in FIG.

In each of FIGS. 7 to 11, the parts designated by the same reference numerals as those in the embodiment shown in FIGS. 1 to 6 are the same or equivalent parts as those in the embodiment.

[Advantages of the Invention] Since the present invention is configured as described above, it has the following effects.

In the connector mounting structure of the present invention, the locking hook piece 2a formed on the insulating base 1 constituting the connector assembly 9 is mechanically formed firmly without moving relative to the insulating base 1. It is robust, and the insulating substrate does not move unintentionally after mounting on the mounted body.

Further, in the assembled structure of the connecting tools 7,7, the connecting tools 7,7 are the insulating base 1
Since it is surrounded by, there is a first effect that the two connecting tools 7, 7 can be mounted with good compatibility through the insulating substrate 1 regardless of a conductive plate or an insulating plate.

Further, since the insulating base 1 is relatively small and the amount of resin used is small, it is economically profitable even if it is molded with expensive heat-resistant plastic, and also a relatively large-sized insulating plate for attachment. Since it is not necessary to use a particularly expensive heat-resistant plastic, the second effect is that the overall cost is reduced.

In particular, in this invention, when a large number of straight tube lamps, fuses, etc. are intensively mounted in a narrow space, the insulating base body 1 to which the two connecting tools have been attached is attached to the attached body by the locking hook pieces 2a, 2a. Since it can be mounted in the 12 mounting holes 10 in a so-called "cassette pon" type, it has a third effect that it can be mounted in a very simple and orderly manner.

Further, in this invention, one pair of clamping pieces 5, 5
5 and the lead wire connecting portion 6 for connecting the lead wire 6a are integrally formed, or the lead wire connecting portion 6a is prefabricated by soldering or crimping the lead wire 6a to the bottom of the connecting tool. Therefore, a soldering iron and a crimping tool, etc., which are required in the above-mentioned prior art, are not required during the vehicle body mounting,
Since the lead wire 6a is pulled out beforehand even in a narrow place or a dark place such as an engine room of an automobile, there is a fourth effect that the lead wire can be easily routed and connected.
