However, the above-mentioned conventional jumper connector 4 has a problem that not only is the shape of the socket contact 5 complicated and the manufacturing cost is high, but also the mounting space is large and it is not suitable for high-density mounting. was there.

The present invention solves the above-mentioned conventional problems. By adopting a conductive elastomer in the connector body of the jumper connector, the manufacturing cost can be greatly reduced with a simple structure and the mounting space can be reduced. An object of the present invention is to provide a jumper connector which can be easily removed and can be easily removed.

[0005]

In order to achieve the above-mentioned object, the present invention is a jumper connector for electrically connecting a plurality of male contacts arranged on a printed wiring board, the connector body comprising: The connector body is provided with a fitting hole for press-fitting and fitting the male contact into contact with the connector body, and the outer portion of the connector body is covered with an electrically insulating cover. And a tab is provided on the electrically insulating cover.

The resistance value of the connector body can be arbitrarily set by adjusting the amount of the conductive filler filled in the conductive elastomer forming the connector body. As the conductive filler, carbon powder is preferable, but conductive metal particles such as copper, nickel and silver may be used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 3 show an example in which the present invention is applied to a jumper connector of a pin header, in which a pin header 12 mounted on a printed wiring board 11 penetrates through a base housing 13 and stands upright. Pin or post 1
4 are arranged in two rows.

The jumper connector 15 is a connector body 1.
6 is formed of a conductive elastomer into a short columnar body having an oval cross section, and two pins or posts 14 and 14 for jumper connection are fitted to both end portions of the connector body 16 so as to come into close contact with each other. 17 and 17, the outer surface of the connector main body 16 is covered so as to be surrounded by an electrically insulating cover 18 formed by an electrically insulating elastomer, and the side surface of the electrically insulating cover 18 is pinched. 19 is integrally provided.

As the conductive elastomer forming the connector body 16, conductive rubber obtained by filling silicon powder with carbon powder as a conductive filler is preferable, but as the conductive filler, a conductive metal such as copper, nickel or silver is used. The particles may be filled. Then, the resistance value of the connector body 16 can be arbitrarily set by adjusting the amount of the conductive filler to be filled. The electrically insulating cover 18 is preferably made of electrically insulating rubber such as silicone rubber without a conductive filler in consideration of compatibility with the connector body 16, but is made of electrically insulating plastic material such as nylon. It may be a hard cover.

The jumper connector 15 having the above structure
For example, as shown in FIG. 4, when the connector body 16 and the electrically insulating cover 18 are extruded as a continuous body 20, a protrusion 21 extending along the side surface of the electrically insulating cover 18 is integrally formed. By cutting the continuous body 20 as shown by the broken line 22, it is possible to mass-produce at low cost. FIG. 5 shows an embodiment of the present invention in which the mounting positions of the knobs 19 are changed. FIG. 5A shows an example in which a pair of knobs 19 extending upward from both sides of the cover 18 are provided.
(B) is an example in which a knob 19 extending over the entire length is provided on one side of the cover 18, (c) is an example in which a pair of knobs 19 extending over the entire length is provided on both sides of the cover 18, (d) Is an example in which a knob 19 is provided at the center of the upper end of the cover 18.

As shown in FIGS. 1 and 2, the jumper connector 15 constructed as described above has a connector body 16 as shown in FIG.
Both fitting holes 17 and 17 are fitted and attached to the two pins or posts 14 and 14 to be connected. Fitting hole 17,
The pins or posts 14, 14 fitted in 17 come into close contact with the inner wall surfaces of the fitting holes 17, 17 due to the elasticity of the connector body 16, and are electrically connected through the connector body 16. At this time, the two pins or posts 14, 14 are jumper-connected with the resistance value of the connector main body 16, so that the connector main body 16 can be connected as described above.
A conductive filler that fills the conductive elastomer constituting the
That is, it is possible to arbitrarily set the resistance value between the connected pins or posts 14, 14 by adjusting the amount of carbon powder. On the other hand, the jumper connector 15 fitted to the two pins or posts 14 and 14 as described above
Can be easily removed by picking and pulling the knob 19.

[0013]

As described above, according to the present invention,
The connector body of the jumper connector is made of a conductive elastomer, and the connector body is provided with a fitting hole for press-fitting and fitting a plurality of male contacts to be connected to each other in a close contact state, and at the outside of the connector body. Since the part is covered with the electric insulating cover and the knob is provided on the electric insulating cover, the structure is simple, the manufacturing cost can be significantly reduced, the mounting space can be reduced, and the high density can be achieved. Suitable for mounting.

On the other hand, at the time of mounting, since the connector body made of the elastomer is closely fitted to the plurality of male contacts to be connected, it has excellent vibration-proofness,
Although it is inevitable that the pullout resistance will increase,
By providing the knob, the jumper connector can be easily removed.

Further, the resistance value of the connector body can be set arbitrarily by adjusting the amount of the conductive filler filled in the conductive elastomer constituting the connector body, so that two pins or posts for jumper connection are used. The resistance value between the two can be set easily and arbitrarily.
