Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ZIF in which a mating connector is slid in a state where a mating number of pin contacts of the mating connector are inserted to contact a mating socket contact provided as a wiping contact.
The present invention relates to a (Zero Insertion Force) type socket side connector.

[0002]

2. Description of the Related Art Conventionally, as this type of socket side connector, for example, one having a structure shown in a front partial sectional view of a connecting structure including it in FIG. 4 can be mentioned.

This connection structure has a predetermined number (4 in this case).
Pin connector 22 as a mating connector, and a socket side connector 10 having a predetermined number (four in this case) of socket contacts 14 combined therewith.

The socket side connector 10 here has four pins 4 into which the pin contacts 22 of the pin side connector 20 can be inserted.
And a movable cover insulator 13 having two insertion holes 13a, mounted on the printed circuit board 30, and
An outer base insulator 11 in which four socket contacts 14 are planted, and this outer base insulator 11
And the pin contact 22 is inserted into the insertion hole 13a of the cover insulator 13, and the pin side connector 20 and the cover insulator 13 are fitted together.
4 housing holes 12 for exposing the wiping contact portion 14a of each socket contact 14 that makes wiping contact with the tip end portion of each pin contact 22 according to the slide of
The inner base insulator 12 provided with a is combined with the outer base insulator 11 and the inner base insulator 12, and a cover insulator 13 is put on the assembly.

That is, when the socket-side connector 10 is combined with the pin-side connector 20 to form a connection structure, each pin contact 22 is passed through the insertion hole 13a of the cover insulator 13 to form the insulator 21 on the cover insulator 13. In this state, the pin side connector 20 and the cover insulator 13 are slid in this state by a slide mechanism such as a cam lever (not shown). As a result, the tip ends of the pin contacts 22 move in the accommodation holes 12a of the inner base insulator 12 and come into contact with the wiping contact portions 14a of the socket contacts 14, respectively.

Incidentally, here, the wiping contact portion 14a.
As is clear from the shape on the plane perpendicular to the sliding direction, the curved convex portion extends in parallel with the sliding direction of each pin contact 22, and therefore, with the wiping contact portion 14a. The wiping range of the pin contact 22 due to the contact is defined to be substantially linear.

[0007]

In the case of the socket-side connector described above, when the mating pin-side connector is combined to form the connection structure, the wiping range of the pin contact by the wiping contact portion of the socket contact is substantially linear. Since the pin contact is defined by a narrow area, only a very small local area receives concentrated contact friction.

In such a structure, if the surface of the contact portion of the pin contact is corroded or foreign matter adheres to it, they cannot be removed sufficiently, and sometimes contact failure occurs. It may happen. In particular, since the contact portion surface of the pin contact is metal, it is chemically unstable and a polluted film is easily formed in the atmosphere, and such a polluted film has a great influence on the electrical performance of the contact. . Therefore, in such a pin contact, it is preferable to increase the wiping amount so that the contaminated coating can be reliably removed, but the above-described configuration of the wiping contact portion has a problem.

The present invention has been made to solve such a problem, and its technical problem is that the wiping amount at the pin contact of the mating pin side connector is increased and the contact portion is corroded. The purpose of the present invention is to provide a socket-side connector in which the removal range of foreign matter adhesion and the like can be expanded to improve contact reliability.

[0010]

According to the present invention, a movable cover insulator having a predetermined number of insertion holes into which a predetermined number of pin contacts of a mating connector can be inserted, and a predetermined number of pin contacts. Socket contacts, which include wiping contact portions that are wiped with the tip portions of the predetermined number of pin contacts according to the sliding of the mating connector and the cover insulator in a state of being penetrated into the insertion holes of In the socket-side connector including an insulator that is planted so as to expose the wiping contact portion, the socket-side connector is provided in which the wiping contact portion is inclined with respect to the sliding direction of the pin contact.

Further, according to the present invention, in the above socket side connector, the wiping contact portion has a socket side connector which defines a wiping range for the pin contact by a width dimension of an inclination in an axial direction in which the pin contact extends. To be

BEST MODE FOR CARRYING OUT THE INVENTION The socket side connector of the present invention will be described below in detail with reference to the drawings. However, the basic structure of this socket-side connector is almost the same as that of the conventional one described in FIG. 4, and therefore, the same components are designated by the same reference numerals to simplify the description and mainly the different portions will be described. .

FIG. 1 is a perspective view showing a main part of a connection structure including a socket side connector according to an embodiment of the present invention. FIG. 1 (a) relates to a state before contact of the contact, The figure (b) relates to the contacting state, and the figure (c) relates to the contact completed state.

The socket-side connector 10 is also formed by covering the assembly of the outer base insulator 11 and the inner base insulator 12 with the cover insulator 13. Here, the assembly (hereinafter simply referred to as an insulator) is used. 1) Socket contact 1
The shapes of 5 are different.

Therefore, referring to FIG. 2A, in the pre-contact state of the pin contact 22 and the socket contact 15, the wiping contact portion 15a has a width dimension h of an inclination in the axial direction in which the pin contact 22 extends. When the contact between the pin contact 22 and the socket contact 15 is completed in this state, the pin contact 22 has the above-described inclined width dimension h as shown in FIG.
The wiping target portion 22a having the wiping range is provided. That is, the wiped portion 22a of the pin contact 22 is nothing but the contact area E _T of the pin contact 22 and the socket contact 15 in FIG.

Therefore, if the connection structure is constructed by combining the socket side connector 10 having such a configuration with the pin side connector 20, the socket contact 15
Due to the inclined wiping contact portion 15a, the wiping range (wiping amount) of the pin contact 22 is increased as compared with the conventional case. As a result, the range of removal of corrosion, adhesion of foreign matter, etc. at the contact portion (tip portion) of the pin contact 22 is expanded, and as a result, contact stability is improved.

Although only the contact operation of the single pin contact 22 and the socket contact 15 has been described in the above-mentioned embodiment, the numbers of these should be appropriately selected according to the application, so that FIG. It is not limited to what is disclosed, including the configurations shown.
