Abstract

According to some embodiments, an electrical connector assembly comprises an electrical connector body and a clamping collar disposed over the electrical connector body. The electrical connector body comprises a pair of opposing latch hook strips parallel to an insertion direction of the electrical connector body. Each latch hook strip has an inward-facing latch hook situated along a distal region of an inner surface of the latch hook strip, and a forward-facing, inner-surface slanted platform. The clamping collar is slidably disposed over the latch hook strips. The clamping collar comprises a pair of backward-facing slanted platforms, each configured to engage a corresponding forward-facing slanted platform of a latch hook strip. Sliding the clamping collar forward along the latch hook strips clamps the latch hooks to secure the connector, and sliding the clamping collar backward along the latch hook strips unclamps the latch hooks to release the connector.

Claims

1. A connector assembly comprising:

an electrical connector body comprising

an elongated tube, and

a pair of opposing latch hook strips coupled to the elongated tube and extending along an outer surface of the elongated tube, each latch hook strip having an inward-facing latch hook situated along a distal region of an inner surface of said each latch hook strip, and

a distally-facing latch supporting slanted platform situated along the inner surface of said each latch hook strip; and

a clamping collar slidably disposed over the latch hook strips and comprising a pair of proximally-facing sliding slanted platforms each configured to engage a corresponding distally-facing supporting slanted platform to transversely press the latch hook strips outward when the clamping collar is slid along the latch hook strips in a proximal direction.

2. The connector assembly of claim 1, wherein the electrical connector body further comprises a proximal threaded coupling and a flange ring, the flange ring being disposed between the proximal threaded coupling and the elongated tube, the threaded coupling having an inner bore in communication with a tube cavity of the elongated tube.

3. The connector assembly of claim 2, wherein said each latch hook strip is coupled to the flange ring, said each latch hook strip comprising a flexing notch defined adjacent to the flange ring, for facilitating a transverse flexure of said each latch hook strip.

4. The connector assembly of claim 1, wherein said each latch hook strip further comprises an outer-wall convex platform situated along a central region of said each latch hook strip and configured to engage an inner surface of the clamping collar to impede a self-release of the clamping collar.

5. The connector assembly of claim 1, wherein said each latch hook strip comprises a flexing notch defined along a proximal region of the latch hook strip, for facilitating a transverse flexure of said each latch hook strip.

6. The connector assembly of claim 1, wherein the elongated tube has a rectangular transverse cross-section.

7. The connector assembly of claim 1, wherein the elongated tube and the pair of latch hook strips are integrally formed.

8. The connector assembly of claim 1, wherein the connector body comprises a connector socket comprising the elongated tube.

9. The connector assembly of claim 8, wherein the external connector comprises a plug electrically connected to the connector socket, the plug comprising a pair of latch hook grooves each sized to receive a corresponding latch hook.

10. A socket clamping structure comprising:

a socket body comprising

a flange ring,

a threaded coupling coupled to the flange ring along a proximal side of the flange ring,

an elongated tube coupled to the flange ring along a distal side of the flange ring, for attaching to an external electrical connector, wherein the elongated tube comprises an inner tube cavity interconnected to an inner bore of the threaded coupling, and

a pair of latch hook strips coupled to the flange ring along the distal side of the flange ring and extending along an outer surface of the elongated tube, the pair of latch hook strips comprising a corresponding pair of latch hooks situated along corresponding distal regions and inner sides of the latch hook strips, the pair of latch hook strips further comprising a corresponding pair of supporting slanted platforms situated along corresponding inner sides of the latch hook strips; and

a clamping collar slidably disposed over the latch hook strips, comprising a pair of sliding slanted platforms along an inner wall of the clamping collar, the sliding slanted platforms being configured to press on the supporting slanted platforms as the clamping collar is slid over the latch hook strips.

11. An electrical connector assembly comprising:

an electrical connector body comprising a pair of opposing latch hook strips parallel to a longitudinal insertion direction of the electrical connector body, each latch hook strip having

an inward-facing latch hook situated along a distal region of an inner surface of said each latch hook strip, and

a distally-facing latch hook strip slanted platform situated along the inner surface of said each latch hook strip; and

a clamping collar slidably disposed over the latch hook strips and comprising a pair of proximally-facing collar slanted platforms each configured to engage a corresponding distally-facing latch hook strip slanted platform, wherein sliding the clamping collar along the latch hook strips in a distal direction clamps the latch hooks to secure the connector body, and wherein sliding the clamping collar along the latch hook strips in a proximal direction unclamps the latch hooks to release the connector body.

12. A method comprising:

hooking an electrical connector body to an external connector by longitudinally sliding a clamping collar toward the external connector along a pair of longitudinal latch hook strips of the electrical connector body to clamp the latch hook strips onto the external connector and hook a pair of inward-facing latch hooks into a corresponding pair of latch hook grooves defined in the external connector, the latch hooks being defined along corresponding distal regions of the latch hook strips, the pair of latch hook strips comprising a corresponding pair of distally-facing, inner-surface supporting slanted platforms, the clamping collar comprising a pair of proximally-facing sliding slanted platforms; and

unhooking the electrical connector body from the external connector by longitudinally sliding the clamping collar away from the external connector along the pair of latch hook strips, wherein the sliding slanted platforms are configured to press onto the supporting slanted platforms as the clamping collar is slid longitudinally away from the external connector.

13. The method of claim 12, further comprising threading a threaded coupling of the electrical connector body to secure a proximal end of the electrical connector body.

14. The method of claim 12, further comprising mating an elongated tube of the electrical connector body to the external connector, the latch hook strips extending along an outer surface of the elongated tube.

15. The method of claim 14, wherein the external connector comprises a plug electrically connected to a connector socket comprising the elongated tube.
