Abstract

An electrical connector assembly includes a plug connector and a receptacle connector. The plug connector includes a first insulating body, a sleeve barrel and a spring. The first insulating body defines a first sliding slot penetrating a front surface thereof. The sleeve barrel is worn outside the first insulating body. The spring is disposed between the sleeve barrel and the first insulating body. A slider block is protruded from a front portion of an inner surface of the sleeve barrel, the slider block is capable of sliding in the first sliding slot. The receptacle connector includes a second insulating body. The second insulating body defines a second sliding slot corresponding to the first sliding slot which includes a longitudinal part penetrating a rear surface of the second insulating body and an inclined part extending sideward and inclining frontward from a front end of the longitudinal part.

First claim

What is claimed is:

1. An electrical connector assembly, comprising:
a plug connector comprising:
a first insulating body including a cylinder shaped base body and an extending portion protruded rearward from a middle of a rear surface of the base body, an outer periphery of the base body defining a first sliding slot penetrating a front surface of the base body, a stopping portion being extended outward from a front portion of a bottom of the first sliding slot;
a sleeve barrel including a barrel body and a barrel end board, the barrel end board being arranged at a rear end of the barrel body, the barrel end board defining a penetration hole, the sleeve barrel being worn outside the first insulating body, the extending portion being received in the penetration hole, a slider block being protruded from a front portion of an inner surface of the barrel body corresponding to the first sliding slot, the slider block capable of sliding in the first sliding slot to pass from and be located in front of the stopping portion;
a spring worn outside the extending portion, one end of the spring abutting against a rear surface of the base body, the other end of the spring abutting against the barrel end board; and
a receptacle connector comprising:
a second insulating body including a cylinder shaped rear end portion which defines a second sliding slot corresponding to the first sliding slot of the first insulating body, the second sliding slot including a longitudinal part with a rear end penetrating a rear surface of the rear end portion and an inclined part extending sideward and inclining frontward from a front end of the longitudinal part;
wherein the first sliding slot of the first insulating body and the second sliding slot of the second insulating body are connected to each other, the sleeve barrel moves towards the receptacle connector, the slider block of the sleeve barrel moves towards the second sliding slot, the sleeve barrel is rotated in clockwise direction until the slider block is locked in a distal end of the second sliding slot, and the spring is compressed by the barrel end board.

2. The electrical connector assembly as claimed in claim 1 , wherein a rear end of the outer periphery of the base body defines a first ring-shaped groove, and the plug connector further comprises an O ring mounted in the first ring-shaped groove.

3. The electrical connector assembly as claimed in claim 1 , wherein the spring is an approximately truncated cone shape, and the one end of the spring which abuts against the rear surface of the base body is narrower than the other end of the spring which abuts against the barrel end board.

4. The electrical connector assembly as claimed in claim 1 , wherein the plug connector further includes a rubber washer mounted on the front surface of the base body, and an outer periphery of the rubber washer defines a connecting groove which connects with the first sliding slot and the second sliding slot.

5. The electrical connector assembly as claimed in claim 1 , wherein a portion of a rear wall of the inclined part protrudes frontward to form a locking portion.

6. The electrical connector assembly as claimed in claim 1 , further comprising a waterproof ring mounted on the rear end portion of the second insulating body and located in front of the second sliding slot, when the slider block is locked in the distal end of the second sliding slot, a front surface of the barrel body is against the waterproof ring.

7. The electrical connector assembly as claimed in claim 6 , wherein an outer periphery of the rear end portion defines a second ring-shaped groove in front of the second sliding slot for mounting a waterproof ring therein.

8. The electrical connector assembly as claimed in claim 1 , wherein the plug connector further comprises a first mating port, the first insulating body is molded outside the first mating port with a front end of the first mating port exposed frontward, and the receptacle connector further comprises a second mating port insert molded in the second insulating body with a rear end thereof exposed from the rear end portion of the second insulating body for mating with the first mating port.

9. The electrical connector assembly as claimed in claim 8 , wherein the plug connector further comprises a cable, an end portion of a cable is mounted in a rear end of the first mating port, and the cable extends out from the extending portion of the first insulating body.

10. The electrical connector assembly as claimed in claim 8 , wherein the first insulating body is molded outside a rear end of the first mating port with the front end of the first mating port exposed outside from a front surface of the base body of the first insulating body.

11. The electrical connector assembly as claimed in claim 10 , wherein the plug connector further includes a rubber washer mounted on the front surface of the base body, an outer periphery of the rubber washer defines a connecting groove which connects with the first sliding slot and the second sliding slot, and the rubber washer defines a hole for receiving the first mating port.

12. A plug connector, comprising:
a first insulating body including a cylinder shaped base body and an extending portion protruded rearward from a middle of a rear surface of the base body, an outer periphery of the base body defining a first sliding slot penetrating a front surface of the base body, a stopping portion being extended outward from a front portion of a bottom of the first sliding slot;
a sleeve barrel including a barrel body and a barrel end board, the barrel end board being arranged at a rear end of the barrel body, the barrel end board defining a penetration hole, the sleeve barrel being worn outside the first insulating body, the extending portion being received in the penetration hole, a slider block being protruded from a front portion of an inner surface of the barrel body corresponding to the first sliding slot, the slider block capable of sliding in the first sliding slot to pass from and be located in front of the stopping portion;
a spring worn outside the extending portion, one end of the spring abutting against a rear surface of the base body, the other end of the spring abutting against the barrel end board;
wherein the spring is an approximately truncated cone shape, and the one end of the spring which abuts against the rear surface of the base body is narrower than the other end of the spring which abuts against the barrel end board.

13. The plug connector as claimed in claim 12 , wherein a rear end of the outer periphery of the base body defines a first ring-shaped groove, and the plug connector further comprises an O ring mounted in the first ring-shaped groove.

14. The plug connector as claimed in claim 12 , further comprising a rubber washer mounted on the front surface of the base body, an outer periphery of the rubber washer defining a connecting groove which connects with the first sliding slot.

15. The plug connector as claimed in claim 12 , further comprising a first mating port, the first insulating body being molded outside the first mating port with a front end of the first mating port exposed frontward.

16. The plug connector as claimed in claim 15 , further comprising a cable, an end portion of a cable being mounted in a rear end of the first mating port, the cable extending out from the extending portion of the first insulating body.

17. The plug connector as claimed in claim 15 , further comprising a rubber washer mounted on the front surface of the base body, an outer periphery of the rub
