Electrical connector

Abstract

To provide an electric connector which can surely regulate a receiving position of a connecting small board so that no positional shift is generated between each electrical contact of the small board and a prescribed contact on a connector side. [MEANS FOR SOLVING PROBLEMS] A rib-shaped positioning protrusion (130) of a socket (100) is provided with a lower section (130b) having a uniform thickness and an upper section (130a) having a portion thicker than the lower section. The both sections are connected by a taper-shaped middle section (130c) which continuously changes in bilateral symmetry. When the width of a notch (13) of the small board (10) to be inserted into the socket (100) is substantially equal to the thickness of the lower section (130b) of the positioning protrusion (130), the small board (10) is positioned by the lower section (130b). When the width of the notch (13) is larger than the thickness of the lower section (130b) of the positioning protrusion (130) and is smaller than the thickness of the upper section (130a), the small board (10)is positioned by the middle section (130c).

Description

technical field [0001] The present invention relates to an electrical connector for accommodating and electrically connecting an end portion of a wiring board on which electrical contacts are formed, and particularly relates to an electrical connector suitable for mounting a memory module in information equipment. Background technique [0002] Conductor patterns (electrical contacts) for contact are provided on the end of a substrate such as a printed wiring board on which electronic components are mounted, and electrical connection is performed by directly inserting the end of the substrate including the electrical contact into an electrical connector. Such an electrical connector for a printed wiring board is called an edge receptacle connector. [0003] Figure 7 An example of a conventional edge receptacle connector (hereinafter simply referred to as receptacle) is shown (Patent Document 1, Figure 9 , Figure 10 ). The socket 500 is configured as a zero insertion for...

Problems solved by technology

[0015] However, if Figure 10 As shown, the pair of retaining arms 632 of the elastic member 630 are not necessarily expanded symmetrically with respect to the center of the positioning protrusion 610b, so if the distance between the multiple contacts of the socket 600 is adjusted according to the requirements of miniaturization and high density (The pitch of the electrical contacts 12 of the small substrate 10) is further reduced, and it is very difficult to make the center of each electrical contact 12 of the inserted small substrate 10 always coincide with the center of the corresponding contact 620 of the socket 600.

Therefore, there is still the problem that it is difficult to limit the storage position of the small substrate 10 so that each electrical contact 12 and the contact 620 can be reliably matched.
