Connector

1. A connector mounted onto a substrate and inserting a connection body with a locking portion from a direction substantially parallel to a mounting face of the substrate, which comprises a required number of contacts each having a contacting portion contacting with the connection body and a connecting portion mounted onto the substrate;

an electrical insulation housing for supporting the contacts and having an insertion port inserting the connection body;

a metallic shell covering the housing; and

a lock member engaging with the locking portion, characterized in that the lock member comprises a first piece provided on an end side thereof with an engaging portion located at a side of the connection body opposite to the mounting face of the substrate and engaged with the locking portion and on the other end side with a pressure receiving portion pressed by the shell, a second piece provided on an end side or other end side with another connecting portion mounted onto the substrate, and a connection portion connecting an approximately middle portion of the first piece to an end or the other end of the second piece; and

the shell comprises a pushing portion arranged at an opposite side of the insertion port and at a position of the shell corresponding to the pressure receiving portion, and a first displacement means facilitating an elastic deformation of the pressure receiving portion.

2. A connector according to claim 1 , wherein the first displacement means is constructed with two slits disposed in the vicinity of both ends in an array pitch direction of the required number of contacts.

3. A connector according to claim 1 , wherein the pressure receiving portion is moved toward a side of the mounting face of the substrate by pushing the pressure receiving portion of the lock member with the pushing portion of the shell in the detaching of the connection body, whereby the engaging portion of the lock member is moved toward a side opposite to the mounting face of the substrate to detach the engaging portion from the locking portion.

4. A connector according to claim 1 , which further comprises a second displacement means facilitating the elastic deformation of the pushing portion.

5. A connector according to claim 2 , wherein the slit is opened in a direction opposite to the insertion port.

6. A connector according to claim 4 , wherein the second displacement means is constructed with an elongated hole extending in the array pitch direction of the required number of contacts.

7. A connector according to claim 1 , wherein the pushing portion of the shell is provided with a reinforcing portion.

8. A connector according to claim 7 , wherein a thickness of the pushing portion inclusive of the reinforcing portion is 0.12 mm-0.20 mm.

9. A connector according to claim 1 , wherein the another connecting portion of the lock member is disposed at a side of the insertion port and the lock member is provided at a side opposing to the pressure receiving portion with an extension portion extended from the connection portion.

10. A connector according to claim 1 , wherein the housing is provided with a groove or a hole at a side opposing to the mounting face of the substrate, in the vicinity of both ends in the array pitch direction and in a position corresponding to the engaging portion of the lock member.

11. A connector according to claim 1 , wherein the contact includes one or both of a first contact segment that a first contacting portion as the contacting portion is disposed at a side of the insertion port and in a position contacting with a side of the connection body opposing to the mounting face of the substrate or a side of the mounting face of the substrate and a first connecting portion as the connecting portion is disposed at a side opposing to the insertion port or at a side of the insertion port and a second contact segment that a second contacting portion as the contacting portion is disposed at a side of the insertion port and in a position contacting with a side of the connection body at a side opposing to the mounting face of the substrate or at a side of the mounting face of the substrate and a second connecting portion as the connecting portion is disposed at a side of the insertion port or at a side opposing to the insertion port, and the first contact segment and the second contact segment are alternately arranged while changing insertion directions into the housing.
