DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a socket connector and, more particularly, to a PC card connector JEIDA / PCM.
The present invention relates to a card-side socket connector defined by the CIA.

[0002]

2. Description of the Related Art As a socket contact of a conventional card-side socket connector, for example, Japanese Unexamined Utility Model Publication No.
There is a multi-point contact type as disclosed in Japanese Patent Publication No. 2 (1994). This type of socket connector aims at a low insertion force of a mating pin to be suitable for a multi-core high-density connector, and a socket contact is formed by connecting three tongue-shaped beams in an annular shape at the base thereof. The parts are connected integrally.

[0003]

However, in this type of socket contact, the bases of the three beams are connected by an annular connecting portion.
When the connector pitch was 1.27 mm, a double pitch of 2.54 mm was required for press punching in the developed state. For this reason, the material cost of the contacts is high, and it is necessary to assemble 17 contacts four times at the time of assembling the connector, resulting in high manufacturing costs.

Further, in the above-mentioned conventional socket connector, since the contact point of the beam is located at a deep position, there is a disadvantage at the time of live connection.

Further, in JEIDA / PCMCIA,
Pin contact length is 5mm for GND / VCC, SIG
Is defined as 4.25 mm and CD as 3.5 mm.
Each of them is required to be in contact with each other in the above-described order when inserted, and to be dissociated in the reverse order when removed. However, since the socket contact of the conventional socket connector has a conical contact structure, the socket contact is affected by the swing of the pin contact and the like, and has a drawback that the sequence required by the above standard cannot be reliably obtained.

The present invention has been proposed in view of the above-mentioned problems of the prior art, and the pitch interval at the time of press punching can be narrowed to improve the efficiency of material removal and reduce the manufacturing cost. , JEIDA / PCMCIA
PC that can reliably obtain the sequence required by
An object of the present invention is to obtain a card-side socket connector of a card connector.

[0007]

According to the present invention, in order to attain the above object, a socket contact which sandwiches a pin contact of a mating pin connector and makes conductive contact is formed by punching a conductive flat plate member having spring properties. Wherein the socket contact is fixedly held by an insulator, wherein the socket contact has first and second contact portions having first and second contact portions that come into contact with a mating pin contact. A beam is provided, and the first beam has a base positioned near a holding portion for the insulator and extends toward an opening of a mating pin contact receiving hole.
The contact portion is located closer to the opening of the mating pin contact receiving hole than the second contact portion, and the second beam has a base located on the opening side and is held by the insulator. And the second contact portion at the tip thereof is located closer to the holding portion to the insulator than the first contact portion, and the first beam is moved to the first contact portion. The width of the portion adjacent to the contact portion of the first
And the width of a portion of the second beam adjacent to the second contact portion is smaller than the width of the first and second contact portions. The bases of the beams are integrally connected by a connecting portion extending into the mating pin contact receiving hole, and the beams are bent from the connecting portion so that their formed contact portions with the mating pin contact face each other. It is characterized by having been done.

Further, the present invention provides a layout for punching out a plurality of the socket contacts from the conductive plate member in a state where the socket contacts are arranged in a pitch direction, the first beam and the first beam of each one of the socket contacts. Are located between the connecting portion of the adjacent socket contact and the second contact portion and between the connecting portion and the second beam, respectively.
It is now arranged.

[0009]

According to the present invention having the above structure, even when the connector pitch is, for example, 1.27 mm, material can be punched at a pitch of 1.27 mm in the developed state. In addition, since the contact point of one beam is arranged on the fitting surface side, live lines can be reliably performed.

A connecting portion 15 is provided so as to extend upward from a meeting portion between the first beam 11 and the fixed holding portion 16, and from an upper end of the connecting portion 15 toward the fixed holding portion side, That is, the second beam 12 is formed so as to extend downward in the drawing.

At the tip (upper end) of the first beam, a first contact portion 13 with a mating pin contact is formed.
A second contact portion is formed at the tip (lower end) of the second beam so as to face the first contact portion 13. More specifically, as shown in FIG. 1, the first contact portion 13 is located closer to the opening of the mating pin contact receiving hole than the second contact portion 14, and the second contact portion The portion 14 is located closer to the holder for the insulator than the first contact portion 13. In addition,
The width of a portion of the first beam 11 adjacent to the first contact portion 13 is smaller than the width of the first and second contact portions 13 and 14, and the second beam 12 has a second width. The width of the portion adjacent to the contact portion 14 is formed smaller than the width of the first and second contact portions 13 and 14. Both beams 11 and 12 are formed so as to be inclined with respect to the fixed holding portion 16 and the connecting portion 15 so as to sandwich the mating pin contact between the contact portions 13 and 14.

A connection portion of the lower end of the socket contact 10 to the substrate is formed at a tip end of a portion bent at a predetermined angle from the fixing portion 16.

FIG. 2 shows a state in which a conductive flat plate member is press-punched to obtain a plurality of the socket contacts 10. As can be seen from this figure, the layout when punching out the conductive plate member in a state where the plurality of socket contacts 10 are arranged in the pitch direction is as follows:

[0018]

As described above, according to the present invention, in the socket connector, in the socket connector, the first beam of the socket contact has the base located near the holding portion to the insulator and the opening of the mating pin contact receiving hole. And the first contact portion at the tip is located closer to the opening of the mating pin contact receiving hole than the second contact portion, and the second beam is The base portion is located on the opening side and extends toward the holding portion to the insulator, and the second contact portion at the tip thereof is higher than the first contact portion with respect to the holding portion to the insulator. The first beam has a width adjacent to the first contact portion that is smaller than a width of the first and second contact portions, and the second beam has a second contact portion that is adjacent to the first contact portion; The width of the part adjacent to the part is Since serial and smaller have been configured from the first and second widths of the contact portions, the material removal of the socket connector can be efficiently, which makes it possible to reduce the manufacturing cost of the socket connector. Also, since the pitch at the time of punching the socket connector can be set to be the same as the pitch of the connector, the connector can be assembled by incorporating the upper and lower two rows respectively, so that the assembly process is simplified,
From this point, a reduction in manufacturing cost can be achieved.

Further, since the first contact is provided near the opening and the second contact is provided near the holding portion, the lengths of the first beam and the second beam can be lengthened to obtain a sufficient contact pressure. And the first and second contact portions are displaced from each other and arranged vertically above and below in the insertion direction of the pin contact, so that the contact between the contact portion and the pin contact is affected by the swing of the pin contact and the like. Therefore, the sequence required by the JEIDA / PCMCIA standard can be reliably obtained.
