Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an electrical connection device with conductive pins used in sockets, connectors, etc.

Construction of conventional examples and their problems Conductive pins used in conventional sockets, connectors, etc. are slidably inserted into through holes in support means, and in most cases, the conductive pins are biased by spring biasing means. Since the conductive pin is biased in one direction, the usual means to prevent the conductive pin from coming off is to form a wide deformed part by caulking at the outer end of the conductive pin in the non-biased direction. 1977
This is shown in Publication No.-27082. However, although these methods are simple, the locking effect tends to be incomplete depending on the degree of caulking, and it is often difficult to secure a working space for complete caulking. There were some aspects where I had to rely on soldering.

Purpose of the invention The present invention fundamentally solves these problems, and has the purpose of reliably preventing the conductive pins from coming off and facilitating connection with external lead wires.

Structure of the Invention In order to achieve this object, the present invention includes a support means having a through hole, a conductive pin slidably penetrating the through hole, a means for urging the conductive pin in one direction, and an electrical connection device with a conductive pin, characterized in that the outer end in the non-energizing direction is inserted and fixed at one end of the conductive tube, and a lead wire is inserted and crimped and fixed at the other end, and the lead wire The conductive tube inserted and fixed by crimping prevents the conductive pin from coming off, and by providing a means for regulating the insertion depth of the conductive pin into the conductive tube, the operating stroke of the conductive pin is made uniform. It is something.

DESCRIPTION OF EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

This embodiment is an example applied to a swan type socket for mounting an arc tube, and an arc tube 2 is mounted to a metal socket tube 1. A part of the support fitting 3 is inserted into the base of the socket tube 1 and fixed by caulking to support the socket tube 1, and from the insulating stepped cylindrical body penetrated through the hole 4 of the support fitting 3. It is provided with a support means 5 consisting of: The part of the support means 5 inside the socket cylinder 1 has an outer diameter slightly smaller than the inner diameter of the socket cylinder 1, and a recessed part 6 formed by deforming a part of the socket cylinder 1 prevents the support means 5 from coming off. It's summery. A conductive pin 8 is slidably passed through the through hole 7 provided in the support means 5, and for example, the large diameter head 9 and the support means 5
The conductive pin 8 is biased in one direction, that is, in the direction of the opening of the socket tube 1, by a biasing means 10 using a spring provided around the conductive pin 8 between the conductive pin 8 and the conductive pin 8.

After the conductive pin 8 is passed through the through hole 7 of the support means 5, the outer end 11 of the conductive pin 8 in the non-energizing direction is
is inserted and fixed into one end of the conductive tube 12, and the conductive tube 12
A lead wire 13 is inserted into the other end and fixed by pressure. More specifically, a threaded portion of a predetermined length is formed on the outer end 11 of the conductive pin 8.
On the other hand, a threaded part is also formed on the inner surface of one end of the conductive tube, and the lead wire 13 is inserted into the other end of the conductive tube 12 and fixed by crimping, and the conductive pin 8 is rotated. The outer end portion 11 is screwed into one end of the conductive tube 12, and the outer end portion 11 with the threaded portion is screwed into the conductive tube 12 until the insertion depth is regulated, and then the detent is inserted. Therefore, one end of the conductive tube 12 is deformed by slightly caulking.

In FIGS. 2 and 3, the deformed portion is indicated by 14. When rotating the conductive pin 8,
Since the head 9 has a non-circular shape with flat surfaces on both sides, it can be easily rotated with a jig. Note that since the outer end 11 of the conductive pin 8 has a threaded part, the conductive pin 8 and the conductive pipe 1 are screwed together with the threaded part on the inner surface of one end of the conductive tube 12.
2 can be sufficiently fixed, the deformation portion 14 of the conductive tube 12 by caulking may not be necessary in some cases. Further, the outer end 11 of the conductive pin 8 is not a threaded part but a mere rough surface, and the inner surface of one end of the conductive tube 12 is also a mere rough surface.
1 may be inserted into one end of the conductive tube 12 and then fixed by caulking. In short, it is sufficient if the conductive tube 12 is sufficiently fixed to the conductive pin 8. Furthermore, the threaded portion itself formed on the outer end portion 11 of the conductive pin 8 is
This serves as a means for regulating the insertion depth of the conductive pin 8 into the conductive tube 12, but the middle of the conductive tube 12 is recessed like a recess 12' where the tip of the lead wire 13 abuts, and the stopper due to this recess is The insertion depth of the conductive pin 8 into the conductive tube 12 may be regulated by the action. In addition, in the drawing, J slots 15 are formed on both sides of the opening side of the socket tube 1, and the pins 17 on both sides of the base 16 of the arc tube 2 pushed into the socket tube 1 are inserted deep inside the J slots 15. This attachment brings the head 9 of the conductive pin 8 into contact with the contact point 18 at the center of the end surface of the base 16, and the conductive pin 8 is in a sliding state against the biasing means 10, while the arc tube 2 is removed, the conductive pin 8 slides toward the opening of the socket cylinder 1 by the biasing means 10, and one end surface of the conductive tube 12 comes into contact with the end surface of the support means 5, preventing the conductive pin 8 from coming off. will be done.

Effects of the Invention According to the invention described above, the outer end in the non-energizing direction of the conductive pin, which is applied with a biasing force and slidably penetrates the through hole of the support means, is inserted and fixed into one end of the conductive tube. Therefore, the conductive tube itself can act to prevent the conductive pin from coming off, and the other end of the conductive tube is crimped and fixed by inserting the lead wire, so the conductive tube alone can act as a mechanical structural element. It has the effect of serving as an electrical connection element,
By providing a means for regulating the insertion depth of the conductive pin into the conductive tube, effects such as the ability to equalize the operating stroke of the conductive pin are achieved.
