Abstract

Disclosed is a four-pin AC parallel connector and a male and a female thereof. The male is composed of a male body, a four-pin male conductor, a retainer, an inner housing, a sleeve, an outer housing and an AC four-pin lead; and the female is composed of a female body, an inner housing, a sleeve, an outer housing, an AC four-pin lead and a four-pin female conductor. The four-pin AC parallel connector and the male and the female thereof of the invention is simple in mounting and dismounting operations, small in volumes and good in sealing property, the working stability is improved, and the service lives are prolonged.

Claims

1. A male of a four-pin AC parallel connector, comprising a male body (101), a four-pin male conductor (102), a retainer (103), an inner housing (104), a sleeve (105), an outer housing (106) and an AC four-pin lead (107), wherein a clamping recess (3) is formed in an end face of the male body (101);

a connecting end of the four-pin male conductor (102) is plugged into the retainer (103);

a through hole (5) matched with a plug end of the four-pin male conductor (102) is formed in the male body (101), and the plug end of the four-pin male conductor (102) is plugged into the through hole (5) in the male body (101);

the inner housing (104) and the sleeve (105) are both placed in a through cavity of the outer housing (106), and the inner housing (104) is placed between the retainer (103) and the sleeve (105);

the AC four-pin lead (107) is connected to the connecting end of the four-pin male conductor (102) after passing through the sleeve (105) and the inner housing (104) successively and being inserted into the retainer (103);

the retainer (103) is embedded on the male body (101); and

the outer housing (106) and the male body (101) are fit and fixed to each other.

2. The male of the four-pin AC parallel connector of claim 1, wherein both of the male body (101) and the four-pin male conductor (102) can be cross-shaped or T-shaped.

3. The male of the four-pin AC parallel connector of claim 1, wherein a stopper groove (6) is formed in the through hole (5).

4. The male of the four-pin AC parallel connector of claim 1, wherein a positioning groove (4) is formed at the location of the through hole (5) in an end face of the male body (101).

5. The male of the four-pin AC parallel connector of claim 1, wherein one side face of the retainer (103) is bumpy.

10. A four-pin AC parallel connector, comprising the male of any one of claims 1-5 and the female of any one of claims 6-9, wherein the tubular connecting end on the female is matched with and plugged into the through hole in the male, and the annular ellipse at the bottom of the tubular connecting end on the female is plugged into the positioning groove (6) of the male;

the sealing ring (7) is located between the outer side of the annular ellipse at the bottom of the tubular connecting end on the female and an inner wall of the positioning groove (6) of the male;

the pins of the female are plugged into and in contact with the plug end of the four-pin male conductor (102) of the male; and

the buckle (11) is plugged and fixed into the clamping recess (3).

6. A female of a four-pin AC parallel connector, comprising a female body (201), an inner housing (104), a sleeve (105), an outer housing (106), an AC four-pin lead (107) and a tubular four-pin female conductor (202), wherein a buckle (10) is further arranged on the female body (201);

the inner housing (104) and the sleeve (105) are both placed in a through cavity of the outer housing (106);

the sleeve (105) is arranged at the top of the inner housing (104);

the AC four-pin lead (107) passes through the sleeve (105) and the inner housing (104) successively and is connected to one end of the four-pin female conductor (202), and the other end of the four-pin female conductor (202) is plugged into the female body (201);

a connecting end of the female body (201) is tubular, and pins at the other end of the four-pin female conductor (202) are arranged in a tube hole in the connecting end of the female body (201); and

the inner housing (104) and the outer housing (106) are both fit and fixed to the female body (201).

7. The female of the four-pin AC parallel connector of claim 6, wherein a plug structure between the other end of the four-pin female conductor (202) and the female body (201) is as follows:

a through groove (9) is formed in a connecting block at the top of the female body (201), and a fixing groove (8) is formed in the tubular four-pin female conductor (202), the position of the fixing groove corresponding to that of the through groove (9), and the tubular four-pin female conductor (202) is fixed by clamping a bumpy fixture block (203) into both the through groove (9) and the fixing groove (8).

8. The female of the four-pin AC parallel connector of claim 6, wherein the top of the connecting end of the tubular female body (201) is arranged on a stop block (11).

9. The female of the four-pin AC parallel connector of claim 6, wherein a sealing ring (7) is sleeved on an outer side of an annular ellipse at the bottom of the tubular connecting end of the female body (201).
