Abstract

An electrical connector includes an insulative housing having a central section defining a plurality of passageways therein for receiving contact elements and two end sections. Two latching members have a U-shaped structure fit over the end sections. Each latching member has a latching arm extending from a bottom wall of the U-shaped structure thereof for engaging with a mating connector. Each latching member has a board lock integrally formed therewith. The board lock includes two spaced resilient legs extending from a side wall of the U-shaped structure for engaging with a hole defined in a circuit board to mount the connector thereto.

Claims

1. An electrical connector adapted to be mounted to a circuit board, comprising an insulative housing having a central section defining a plurality of passageways therein for receiving contact elements in electrical engagement with the circuit board and two end sections, and two latching members each having a U-shaped structure fit over the corresponding end section, a latching arm extending from a bottom wall of the U-shaped structure for engaging with a mating connector, the improvements comprising a board lock having two spaced resilient legs integrally formed with and extending from a side wall of the U-shaped structure and adapted to engage with a hole defined in the circuit board to mount the connector thereto.

2. The electrical connector as claimed in claim 1, wherein the resilient legs have expanded ends.

3. The electrical connector as claimed in claim 2, wherein the expanded ends are formed by bending each resilient leg outward.

4. The electrical connector as claimed in claim 1, wherein each end section of the housing comprises a projection having a face in contact engagement with the latching arm of the corresponding latching member for supporting the latching arm.

5. The electrical connector as claimed in claim 4, wherein each latching arm comprises flanges engaging with an end of the corresponding projection for providing increased support thereto.

6. The electrical connector as claimed in claim 1, wherein the latching member is made from a single metal plate and defines a hole in the bottom wall thereof forming a cylindrical extension projecting from a periphery thereof, and wherein a recess is defined in each end section and exposed to a front face thereof for accommodating the cylindrical extension, the recess being further exposed to a side face of the end section for facilitating insertion of the extension therein.

7. The electrical connector as claimed in claim 6, wherein the end section defines a bore therein corresponding to the hole of the latching member, a shielding member being attached to the central section with side tabs thereof abutting against the bottom walls of the latching members, each side tab defining a hole corresponding to the hole of the latching member, the bore of the end section of the housing and the holes of the latching member and the shielding member being aligned with each other and adapted to receive a fastener therethrough for securing the shielding member and the latching member to the corresponding end section of the housing.

8. The electrical connector as claimed in claim 1, wherein the bottom wall of the latching member abuts against a front face of the end section, the latching member further having two side walls respectively abutting against top and bottom faces of the end sections, each side wall having a first flange engaging with a rear face of the end section.

9. The electrical connector as claimed in claim 8, wherein at least one of the first flanges is J-shaped and received in a slot defined in the end section.

10. The electrical connector as claimed in claim 9, wherein each side wall of the latching member has a J-shaped second flange received in a slot defined in the end section of the housing.

11. The electrical connector as claimed in claim 8, wherein each side wall further comprises a third flange engaging with the front face of the end section.

12. The electrical connector as claimed in claim 8, wherein each side wall of the latching member defines an opening for engaging with a barb formed on the corresponding end section of the housing.

13. The electrical connector as claimed in claim 1, wherein each end section has a support face distanced from a bottom face thereof and adapted to be positioned on the circuit board to support the connector thereon.

14. An electrical connector comprising an insulative housing defining two end sections at two opposite ends, a latching member being disposed unto each of said end sections, said latching member defining a U-shaped structure including an upper side wall, a lower side wall and a bottom wall therebetween, a latching arm extending perpendicularly from the bottom wall of said U-shaped structure, said upper side wall and said lower side wall further including flanges for guidable engagement with the connector, a board lock integrally formed with one of said upper side wall and said lower side wall, and lying in a plane parallel to said latching arm.
