The present invention relates to a connector technology, particularly to a lamp connector.
DESCRIPTION OF THE RELATED ART
At present, the conventional lamp connector normally includes a male connector and a female connector, each of which is formed of a plastic body, and a positive contact and a negative contact inside the plastic body. The engagement of the contact and the body is realized by a barb structure. Such an engagement mechanism needs a more complicated structural design and a more troublesome assembly process but has a poorer engagement effect. Besides, the engagement of the male connector and the female connector of the conventional lamp connector merely relies on the elastic force of the front portions of the contacts and is more likely to loosen. Especially, the conventional lamp connector is likely to suffer poor contact after long-term usage. Therefore, the conventional lamp connector has a shorter service life. Further, the positive contact and the negative contact of the conventional lamp connector are disposed in a common accommodation space and are more likely to be affected by electromagnetic interference. Such a problem would affect the performance of products.
SUMMARY OF THE INVENTION
The objective of the present invention is to provide a novel lamp connector to overcome the drawbacks of the conventional lamp connector.
The technical scheme to realize the objective of the present invention is a lamp connector comprising a connector body and a contact, wherein the connector body has an accommodation space accommodating the contact, wherein the tail portion of the contact has a positioning hole, and wherein each connector body has a slot extending along the insertion direction of the contact on the two inner walls thereof, and wherein two edge fins of the contact are confined to the slot, and wherein the accommodation space has a elastic member, and wherein a barb protrudes from the elastic member and corresponds to the positioning hole, and wherein the front surface of the barb has a guide slope.
In one embodiment, the lamp connector of the present invention comprises a male plug and a female socket. The male plug includes a plug body and a plug contact. The plug body has an insert member and a first accommodation space accommodating the plug contact. The female socket includes a socket body and a socket contact. The socket body has an insert receiver corresponding to the insert member and a second accommodation space accommodating the socket contact,

    
    
        wherein the tail region of the plug contact has a first positioning hole; the first accommodation space has first slots extending along the insert direction of the plug contact on two sidewalls; the first accommodation space also has a first elastic member; the first elastic member further has a first barb protruding from the first elastic member and corresponding to the first positioning hole; the first barb further has a first guide slope on the front surface thereof; and
        wherein the tail region of the socket contact has a second positioning hole; the second accommodation space has a second slot extending along the insert direction of the socket contact on two sidewalls; the second accommodation space also has a second elastic member; the second elastic member further has a second barb protruding from the second elastic member and corresponding to the second positioning hole; the second barb further has a second guide slope on the front surface thereof; and
        wherein the front end of the socket contact has a recessed contact portion; the front end of the socket contact is bent upward and backward to form a first bent portion pressing against the inner upper wall of the socket body; and
        wherein the front end of the plug contact is bent downward to form a second bent portion; and
        wherein the plug body has a positive insert member and a negative insert member, which are separated from each other; correspondingly, the insert receiver of the socket body has a separation wall.
    
    


In the present invention, the slot, the elastic member and the barb in the plastic body cooperate with the positioning hole of the contact to complete the assemblage of the body and contacts.

DETAILED DESCRIPTION OF THE INVENTION
Refer to FIG. 7 for a concise description of the present invention beforehand. The present invention proposes a lamp connector comprising a male plug and a female socket. The male plug includes a plug body and plug contacts. The female socket includes a socket body and socket contacts. The bodies respectively have accommodation spaces accommodating the contacts. The tail portion of the contact has a positioning hole. Each body has slots extending along the insertion direction of the contacts on the inner walls thereof. Two edge fins of the contact are confined to the slots. The accommodation space has elastic members. A barb protrudes from the elastic member and corresponds to the positioning hole. The front surface of the barb has a guide slope.
Below, embodiments are described in detail in cooperation with the attached drawings to demonstrate the technical contents of the present invention.
The lamp connector of the present invention comprises a male plug 1 and a female socket 2. Refer to FIGS. 1-3. The male plug 1 includes a plug body 11 and plug contacts 12. The plug body 11 has an insert member 111 and a first accommodation space 101 accommodating the plug contacts 12. Refer to FIGS. 4-6. The female socket 2 includes a socket body 21 and socket contacts 22. The socket body 21 has an insert receiver 211 corresponding to the insert member 111 and a second accommodation space 201 accommodating the socket contacts 22.
The tail region of the plug contact 12 has a first positioning hole 121. The first accommodation space 101 has first slots 102 on two sidewalls along the insert direction of the plug contacts 12. Two edge fins of the plug contact 12 are confined to the first slots 102. The first accommodation space 101 also has first elastic members 103. The first elastic member 103 further has a first barb 104 corresponding to the first positioning hole 121. The first barb 104 further has a first guide slope 105 on the front surface thereof.
