Abstract

PURPOSE:To provide a connector, with which the parts cost and assembly cost can be reduced. CONSTITUTION:A contact member 9 configured with insulative rubber 10 and electroconductive rubber 11 which are laminated alternately, is inserted into a housing 13 from an opening 13a in such an arrangement that the tip of the contact member 9 is left protruding a little from the opening 13a. One end of a harness 13 is held by the harness holding part 5 of a solderless terminal 5. A spring part 5b of this solderless terminal 5 is in pressure contacting with the electroconductive rubber part of the contact member 9. When a hook 14 on the housing 13 is fitted in a hole 16 provided in base board, the housing 13 is secured onto the base board 3. and the electroconductive rubber part of the contact member 9 is put in pressure contacting with a conductor pattern 15.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for connecting a harness used in a copying machine or the like to a conductor pattern formed on a substrate.

0002

2. Description of the Related Art In FIG. 6, reference numeral 3 indicates a substrate, on which a conductive pattern is formed. A male connector 2 is fixed to the board 3, and a pin 19 is provided on the male connector 2. This pin 19 is soldered to a conductor pattern on the board 3. Reference numeral 1 indicates a female connector 1, to which a harness 4 is attached. The female connector 1 is fitted into the male connector 2, and the harness 4 and the conductor pattern are connected via pins 19.

0003

However, in the conventional example described above, the female connector 1 and the male connector 2 are combined as a pair, and the pins 19 must be soldered to the board 3, which increases component costs and assembly costs. There is a problem that the value becomes high. The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a connector that can keep component costs and assembly costs low.

0004

[Means for Solving the Problems] The invention according to claim 1 provides a contact member formed by alternately laminating insulating rubber and conductive rubber, and a holding member for holding the contact member.
A contact means for contacting and fixing the signal transmission member to the conductive rubber portion of the contact member, and a mounting means for attaching the holding member onto the substrate with the conductive rubber portion of the contact member in contact with the conductive pattern. It is a connector.

[0005] A second aspect of the present invention is the connector according to the first aspect, wherein the contact means is a crimp terminal comprising a holding portion that holds the signal transmission member and a spring portion that presses against the contact member.

A third aspect of the present invention is the connector according to the first aspect, wherein the attachment means is a hook formed on the holding member and detachable from the hole in the substrate.

[0007]

[Operation] In the present invention, the holding member is attached to the substrate so that the contact member made of alternately laminated insulating rubber and conductive rubber and the conductive rubber portion are in contact with the conductive pattern. ,, the signal transmission member is electrically connected to the conductor pattern on the substrate via the contact member.

[0008]

[Embodiment] An embodiment of the present invention will be explained with reference to the drawings. Reference numeral 13 indicates a housing as a holding member, and this housing 13 has an opening 13a formed therein. Reference numeral 9 indicates a contact member, and this contact member 9
is constructed by alternately laminating insulating rubber 10 and conductive rubber 11. Contact member 9 is inserted into housing 13 through opening 13a. As shown in FIG. 3, the contact member 9 is dimensioned so that its tip slightly protrudes from the opening 13a when it is housed in the housing 13.

One end of the harness 13 as a signal transmission member is connected to an electronic device (not shown), and the other end is connected to the housing 1.
3 into the housing 13b from the intake port 13b. The harness 13b is held by a crimp terminal 5 as a contact means. The crimp terminal 5 is made of conductive metal.

As shown in FIG. 4, the crimp terminal 5 includes a harness holding portion 5a and a spring portion 5b integrally formed with the harness holding portion 5a. The harness 4 is held by the harness holding portion 5a, and the spring portion 5b is in pressure contact with the conductive rubber 11 portion of the contact member 9.

A pair of hooks 14 are provided on the housing 13 as attachment means, and the hooks 14 protrude from the front side of the housing 13. Housing 1
3 is formed with a groove 18 extending along both sides of the hook 14, and the groove 18 allows the hook 14 to be elastically deformed in the longitudinal direction of the housing 13. Reference numeral 3 indicates a substrate, on which a conductor pattern 15 is formed. Further, rectangular holes 16 are formed on both sides of the conductive pattern 15 in correspondence with the hooks 14.

When the hook 14 is inserted into the hole 16, the hook 1
4 elastically deforms inward, and when inserted into the hole 16,
The housing 13 is restored to its original state and fixed onto the substrate 3. When the housing 13 is fixed on the substrate 3, the conductive rubber 11 portion of the contact member 9 is pressed against the conductive pattern 15. Note that since the hook 14 can be elastically deformed, it can also be pulled out from the hole 16, and the housing 13 can be attached to and detached from the board 3.

In this connector, the harness 4 and the conductor pattern 15 are electrically connected via the crimp terminal 5 and the conductive rubber 11 of the contact member 9. An inclined hole 59 whose bottom surface is inclined like the contact member 59 shown in FIG.
a, the contact member 59 is connected to the housing 13.
It is possible to reliably prevent it from falling out of the hole 13a.

[0014]

As described above, according to the present invention, there is no need to provide both a female connector and a male connector, unlike the conventional example, and there is no need to solder pins to the board. Therefore, parts costs and assembly costs can be kept low.
