Electronic part-mounting socket

Abstract

An electronic part-mounting socket (100) includes a shielding housing (3) defining a receiving cavity (34) for receiving an electronic part. Each of opposed side wall sections (31) of the shielding housing defines a hinge edge (314) with opposed sides. Each side wall section has a portion bent as a resilient contact tongue (315), which is joined to one side of the hinge edge and has a free end thereof inwardly projecting into said receiving cavity for resiliently retaining the electronic part. An extension piece (316) is integrally joined to the other side of the hinge edge and constructed to allow the resilient contact tongue to flex about the hinge edge. Thus, as compared with the prior art, the resilient contact tongue will have a better resilient capability due to the additional extension piece, even after the repeated application of the socket.

Claims

1. An electronic part-mounting socket comprising: a shielding housing defining a base section surrounded by a peripheral wall so as to form a receiving cavity therebetween for receiving an electronic part, said peripheral wall including a first pair of opposed side wall sections, each side wall section defining a hinge edge with opposed sides;the side wall section having a portion bent as a resilient contact tongue, the resilient contact tongue integrally joined to one side of said hinge edge and having a free end thereof inwardly projecting into said receiving cavity for resiliently retaining the electronic part;an extension piece integrally joined to the other side of said hinge edge and constructed to allow said resilient contact tongue to flex about said hinge edge.

2. The electronic part-mounting socket of claim 1, wherein the housing includes a second pair of opposed side wall sections, a plurality of contacts arranged in a row and disposed along a respective one of said second pair of opposed side wall sections.

3. The electronic part-mounting socket of claim 2, further comprising a contact holding member made of an insulative material, the contact holding member for holding the contacts in position.

4. The electronic part-mounting socket of claim 2, wherein each of the contacts includes a mating portion extending from said base section of the shielding housing for electrically mating with a corresponding conductive element of the electronic part, and a mounting portion extending outwardly of a corresponding one of said second pair of side wall sections for solderably mounting onto a printed circuit board.

5. An electrical connector comprising: a metallic shell defining four side walls and a bottom wall commonly defining a receiving space;a pair of Z-shaped contact holding members upside down attached to opposite two of said side walls, each of said contacts holding members including a plurality of contacts each including an upper horizontal section for engagement with a printed circuit board which has an opening receiving said shell therein, and a lower upwardly obliquely contact section for engagement with an electronic component received in said receiving space; anda pair of metallic shielding pieces cooperating with said opposite two of the side walls to sandwich the corresponding contact holding members, respectively.

6. The connector as claimed in claim 5, wherein the other two opposite of said side walls form resilient contact tongues for retaining the electronic component in the receiving space.

7. The connector as claimed in claim 5, wherein said opposite two of said side walls define horizontally extending legs at upper edges thereof coplanar with the upper horizontal section.

8. The connector as claimed in claim 5, wherein the other two opposite of said side walls define a plurality of horizontally extending tags for engagement with the printed circuit board.

9. The connector as claimed in claim 5, wherein said shielding pieces define a plurality of downwardly extending tags for engagement with the printed circuit board.

10. The connector as claimed in claim 6, wherein an upper face of the shielding piece is essentially coplanar with a downward engagement face of the resilient contact tongue which is adapted to engage the printed circuit board.
