Abstract

An electrical connector (10) includes an insulative housing (12), a number of contacts (14) received in the housing and a pair of board locks (16) attached to opposite side faces (18) of the housing. The housing provides a pair of guiding blocks (28) and a pair of retention portions (36) outwardly extending from the side faces of the housing. The guiding blocks are located above the retention portions and a space is defined between each guiding block and a corresponding retention portion for facilitating assembly of the board lock to the retention portion. Each retention portion does not extend beyond a plane defined by an outermost surface of the guiding block in a longitudinal direction of the housing and the board lock is located between the outermost surface of the guiding block and the side face of the housing, thereby minimizing the longitudinal dimension of the connector.

Claims

1. An electrical connector comprising:

an elongated insulative housing having a mating surface, a mounting surface and a pair of opposite side faces, the housing including a block protruding outwardly from one of the side faces in a longitudinal direction of the housing;

a plurality of conductive contacts received in the housing;

a fastener fixed to the housing and located under the block inwardly of a plane defined by an outermost surface of said block;

wherein the block serves as a guiding post for guiding the connector to a mating connector;

wherein the housing includes a retention portion to which said fastener is fixed, a space being defined between the block and the retention portion; and

wherein the retention portion includes two pieces spaced from each other in a transverse direction of the housing between which the fastener is sandwiched.

2. The electrical connector as claimed in claim 1, wherein the block is located adjacent the mating surface of the housing and has a section protruding beyond the mating surface.

3. The electrical connector as claimed in claim 1, wherein the retention portion does not exceed the plane defined by the outermost surface of the block in the longitudinal direction of the housing.

4. The electrical connector as claimed in claim 1, wherein a space is defined between a bottom surface of the block and an upper surface of the retention portion.

5. The electrical connector as claimed in claim 1, wherein the retention portion is integrally formed at an end portion thereof and has a section extending beyond the mounting surface of the housing to serve as a stand-off.

6. The electrical connector as claimed in claim 1, wherein the retention portion defines a groove for securely receiving the fastener therein.

7. The electrical connector as claimed in claim 1, wherein each contact has a mounting portion horizontally and outwardly extending a predetermined distance and then downwardly extending a predetermined distance.

8. The electrical connector as claimed in claim 1, wherein the fastener goes a curvilinear trail when it is assembled to the retention portion.

9. The electrical connector as claimed in claim 1, wherein the fastener is a board lock.

10. An electrical connector comprising:

an insulative housing having a mating surface, a mounting surface, two opposite side faces and defining a plurality of cavities and a slot between the mating surface and the mounting surface, the housing providing a block and a retention portion on one of the side faces thereof, a space being defined between the block and the retention portion;

a plurality of conductive contacts received in the respective cavities of the housing;

a fastener fixed to the retention portion of the housing and located under the block; and

wherein the block serves as a guiding post for guiding the connector to a mating connector.

11. The electrical connector as claimed in claim 10, wherein each retention portion does not exceed beyond a plane defined by an outmost surface of the respective block.

12. The electrical connector as claimed in claim 10, wherein the fastener is located between one of the side faces of the housing and an outmost surface of the block.

13. The electrical connector as claimed in claim 10, wherein the retention portions are located under the respective blocks and does not extend shades of the respective blocks in a longitudinal direction of the housing.

14. The electrical connector as claimed in claim 13, wherein each retention portion has a section extending beyond the mounting surface of the housing to provide stand-off function.

15. An electrical connector comprising:

an insulative housing with a plurality of contacts therein;

a pair of engagement blocks positioned at two opposite ends of the housing, respectively;

a pair of retention portions positioned at said two opposite ends of the housing, respectively, each of said retention portions generally aligned with the corresponding one of said engagement blocks in a direction perpendicular to a lengthwise direction of said housing;

a space being formed between said each of said retention portions and the corresponding engagement block;

wherein because of said space, a fastener is assembled to the corresponding retention portion through a curved top loading manner; and

wherein each block serves as a guiding post for guiding the connector to a mating connector.
