Abstract

An electrical connector is provided for terminating an electrical cable and for mating with a complementary mating connector. A dielectric housing includes a front mating end, a rear terminating end and at least one mounting slot therein. A one-piece latch and strain relief device includes a central mounting portion, a forward latching portion and a rearward strain relief portion. The central mounting portion includes a mounting tab insertable into the mounting slot in the housing. The forward latching portion is adapted for latching engagement with the mating connector. The rearward strain relief portion is adapted for engaging the electrical cable. The one piece latch and strain relief device is electrically connected to the upper and lower shielding shells.

Claims

1. An electrical connector for terminating an electrical cable and for mating in a mating direction with a complementary mating connector, comprising:

a dielectric housing having a front mating end, a rear terminating end and a surface adapted to receive a latch and strain relief device with at least one mounting slot therein said mounting slot extending in said mating direction perpendicular into said surface;

a plurality of terminals mounted in the housing and extending generally between said ends thereof;

the one-piece latch and strain relief device including a central mounting portion, a forward latching portion and a rearward strain relief portion,

said central mounting portion including a mounting tab insertable into the mounting slot in the housing,

said forward latching portion being adapted for latching engagement with the mating connector, and

said rearward strain relief portion being adapted for engaging the electrical cable.

2. The electrical connector of claim 1 wherein said one-piece latch and strain relief device is stamped and formed of sheet metal material.

3. The electrical connector of claim 1 wherein said forward latching portion comprises at least one forwardly projecting latch arm.

4. The electrical connector of claim 1 wherein said forward latching portion comprises a pair of hooked latch arms located at opposite sides of said front mating end of the housing.

5. The electrical connector of claim 2 wherein said forward latching portion comprises a pair of said latch arms at least partially supported in latch arm receiving slots in the housing at opposite sides of said front mating end of the housing.

6. The electrical connector of claim 1 wherein said rearward strain relief portion comprises a crimp portion for clamping onto the electrical cable.

7. The electrical connector of claim 1 wherein said central mounting portion includes a pair of said mounting tabs press-fit into a pair of said mounting slots at opposite sides of the housing.

8. An electrical connector for terminating an electrical cable and for mating in a mating direction with a complementary mating connector, comprising:

a dielectric housing having a front mating end, a rear terminating end and a surface adapted to receive a latch and strain relief device with at least one mounting slot therein, said mounting slot extending in said mating direction perpendicular into said surface;

a plurality of terminals mounted in the housing and extending generally between said ends thereof;

the one-piece latch and strain relief device stamped and formed of sheet metal material and including a central mounting portion, a forward latching portion and a rearward strain relief portion,

said central mounting portion including a mounting tab insertable into the mounting slot in the housing,

said forward latching portion including at least one forwardly projecting latch arm for latching engagement with the mating connector, and

said rearward strain relief portion including a crimp member for clamping onto the electrical cable.

9. The electrical connector of claim 8, wherein said forward latching portion comprises a pair of hooked latch arms located at opposite sides of said front mating end of the housing.

10. The electrical connector of claim 8 wherein said forward latching portion comprises a pair of said latch arms at least partially supported in latch arm receiving slots in the housing at opposite sides of said front mating end of the housing.

11. The electrical connector of claim 8 wherein said central mounting portion includes a pair of said mounting tabs press-fit into a pair of said mounting slots at opposite sides of the housing, each mounting tab having opposite straight edges engagable with straight edges of said mounting slots.

12. An electrical connector for mating with a complementary mating connector, comprising:

a dielectric housing having a front mating end, a rear terminating end and at least one mounting slot therein, said mounting slot extending in a mating direction perpendicular into said surface;

a plurality of terminals mounted in the housing and extending generally between said ends thereof;

a one-piece latch and strain relief device stamped and formed of sheet metal material including a mounting portion and a forward latching portion, said mounting portion including a mounting tab insertable into the mounting slot in the housing, and said forward latching portion being adapted for latching engagement with the mating connector; and

a first shielding shell member beneath said one piece latch and strain relief device.

13. The electrical connector of claim 12 wherein said first shielding shell member includes a mounting tab insertable into said mounting slot in the housing.

14. The electrical connector of claim 13 wherein said forward latching portion comprises at least one forwardly projecting latch arm.

15. The electrical connector of claim 13 wherein said forward latching portion comprises a pair of hooked latch arms at opposite sides of said front mating end of the housing.

16. The electrical connector of claim 13 including a second shielding shell member stamped and formed of sheet metal material having side tabs disposed in a second mounting slot in the housing.

17. The electrical connector of claim 12 wherein said forward latching portion comprises a pair of said latch arms at least partially supported in slots in the housing at opposite sides of said front mating end of the housing.

18. The electrical connector of claim 12 wherein said mounting portion includes a pair of said mounting tabs press-fit into a pair of said mounting slots at opposite sides of the housing.
