Abstract

Card edge connectors that are reliable and robust against impacts by external forces while having narrower widths by industry standards. A connector includes a housing having a body with a slot elongated longitudinally. The housing has a pair of towers extending vertically from opposite ends of the longitudinal slot. Each tower has a slot elongated vertically, and is narrower than the body in a transverse direction. The longitudinal slot and the vertical slots are configured to receive edges of an electronic card. The connector has a pair of reinforcing members. Each reinforcing member is at least partially disposed on a tower and configured to support a joint between the tower and the body of the housing. Such a configuration can increase robustness of the connector at the joints and therefore reduce the risks of deforming or cracking the towers when the connector is impacted by an external force.

First claim

What is claimed is:

1 . An electrical connector, comprising:
a housing comprising
a body comprising a mounting surface and an interfacing surface opposite to the mounting surface in a vertical direction,
a tower protruding from an end of the interfacing surface in the vertical direction, and
a slot comprising a first portion extending in the body in a longitudinal direction perpendicular to the vertical direction and a second portion extending in the tower in the vertical direction; and
a reinforcing member comprising
a first portion at least partially wrapping a distal end of the tower, and
a second portion extending in the vertical direction beyond a joint between the tower and the body, wherein the second portion of the reinforcing member extends into the body of the housing by insertion into the first portion of the slot.

2 . The electrical connector of claim 1 , wherein:
the reinforcing member spans the joint and is connected to both the tower and the body of the housing.

3 . The electrical connector of claim 1 , wherein:
the joint is a first joint between the tower and the body on a first side of the slot; the reinforcing member comprises a third portion extending in the vertical direction beyond a second joint between the tower and the body; and the second joint is on a second side of the slot opposite the first side.

4 . The electrical connector of claim 1 , wherein:
the first portion of the reinforcing member is on an exterior of the tower.

5 . The electrical connector of claim 1 , wherein:
the tower comprises a pair of side walls disposed on opposite sides of the slot in a transverse direction perpendicular to both the vertical direction and longitudinal direction, and an end wall connecting the pair of side walls; the pair of side walls and the end wall at least partially surround the second portion of the slot; and the second portion of the reinforcing member extends along a side wall of the pair of side walls.

6 . The electrical connector of claim 5 , wherein:
the second portion of the reinforcing member comprises two parts, each of the two parts extending along a side wall of the pair of side walls.

7 . The electrical connector of claim 5 , wherein:
the first portion of the reinforcing member extends along the pair of side walls in the longitudinal direction and the end wall in the transverse direction.

8 . The electrical connector of claim 1 , comprising:
a plurality of conductive elements, each of the plurality of conductive elements comprising a mating contact portion curving into the first portion of the slot, and a mounting contact portion extending out of the body through the mounting surface.

9 . The electrical connector of claim 1 , wherein:
a transverse width of the tower is less than a transverse width of the body of the housing.

10 . An electrical connector, comprising:
a body comprising a slot extending in a longitudinal direction and a recess at an end of the slot; a latch pivotably connected to the body at a location in the recess and configured to move between a locked position and an unlocked position; a tower disposed between the slot and the recess of the body and extending in a vertical direction perpendicular to the longitudinal direction, the tower being narrower than the body in a transverse direction perpendicular to both the longitudinal direction and the vertical direction; and a reinforcing member disposed on the tower and comprising a portion elongated in the vertical direction to or beyond a position aligned with the location in the recess in the longitudinal direction.

11 . The electrical connector of claim 10 , wherein:
the tower comprises a first recess extending along an outer side surface of the tower and into the body beyond a plane that an interfacing surface extends; and the reinforcing member is at least partially disposed in the first recess of the tower.

12 . The electrical connector of claim 11 , wherein:
the body comprises a plurality of second recesses extending toward a mounting surface; the plurality of second recesses of the body are spaced apart in the longitudinal direction; and the reinforcing member comprises a plurality of tabs extending toward the mounting surface and disposed into respective ones of the plurality of second recesses.

13 . The electrical connector of claim 10 , wherein:
the portion of the reinforcing member elongated in the vertical direction is embedded in the tower.

14 . The electrical connector of claim 13 , wherein:
the portion of the reinforcing member extends into the body by insertion into the slot.

15 . The electrical connector of claim 13 , wherein:
the portion of the reinforcing member elongated in the vertical direction is rod-shaped.

16 . The electrical connector of claim 10 , wherein:
the reinforcing member further comprises a portion having a U-shaped cross-section in a plane perpendicular to the vertical direction with an opening of the U-shaped cross-section facing the slot.

17 . The electrical connector of claim 16 , wherein:
the tower comprises a first block protruding from a side wall and extending to an end wall and configured to at least partially support the portion of the reinforcing member having the U-shaped cross-section.

18 . The electrical connector of claim 17 , wherein:
the tower comprises a second block protruding from the side wall and having one end extending to a distal end of the tower and an other end extending to the body.

19 . The electrical connector of claim 18 , wherein:
the tower comprises a first recess between the first block and the second block; and the reinforcing member is at least partially disposed in the first recess of the tower.

20 . An electrical connector, comprising:
a housing comprising a body having a slot elongated in a longitudinal direction, a pair of towers disposed on opposite ends of the slot and extending in a vertical direction perpendicular to the longitudinal direction; a plurality of conductive elements held by the body of the housing, each of the plurality of conductive elements comprising a mating contact portion curving into the slot, and a mounting contact portion extending out of the body of the housing; and a pair of reinforcing members each at least partially disposed on one of the pair of towers and configured to support a joint between the body of the housing and a respective tower, wherein at least one of the pair of towers comprises a first block protruding from a side wall and extending to an end wall and configured to at least partially support a portion having a U-shaped cross-section of a respective reinforcing member of the pair of reinforcing members.
