Abstract

The utility model relates to a connecting device and especially to a connector in the connecting device. The connector provided by the utility model comprises a body, a first terminal and a second terminal fixedly arranged in the body and a shielding housing assembled out of the body, wherein a first contact part of the first terminal is provided with a projecting part. The utility model has the following beneficial effects: since the first contact part of the first terminal is provided with the projecting part, insertion and extraction force of the connector and a butt joint plug is greatly increased, contact failure is avoided, and stability of electric power transmission is improved.

Description

Electric connector

[technical field]

The utility model provides a kind of electric connector, relates in particular to a kind of electric connector that increases chucking power.

[background technology]

Electric connector is widely used in the fields such as electronics, information, communication, photoelectricity, and wherein power connector has two-terminal and serves as respectively positive pole and the negative pole of power supply, and power connector is exactly that the both positive and negative polarity of nationality terminal comes to provide operating voltage for electronic building brick.Usually, establishing connector body or plug in the two ends of cable group forms in order to the be separated by power supply of a segment distance and the power supply of electronic building brick of connection and connects machine assembly; Perhaps, existing power connector also can be arranged on the circuit board, and can mutually be electrically connected with the power connector of a coupling.

And after connector process use a period of time of the prior art, it is inadequate the clamping dynamics to occur, causes the problems such as transmission reliability reduction of electric power or signal.

[summary of the invention]

Hold the power deficiency in order to solve to add in the prior art, the problem of loose contact, the utility model changes the structure of existing electric connector, and a kind of power of holding that adds that increases connector body and banjo is provided, thereby improves the electric connector of the transmission reliability of electric power or signal.

The utility model provides a kind of electric connector, comprises a body and is fixedly arranged on the first terminal, second terminal of described body and is assembled in this external shielding casing.

Described body has a reception room, in the fixed block that the reception room inwall is provided with plurality of grooves and arranges in groove one end, above-mentioned groove is used for installing the first terminal, fixed block is used for fixedly the first terminal.

The first terminal comprises fixed part, the first contact site and the second contact site that extend with the connecting portion that holds tongue piece, extends in fixed part of fixed part setting, in the fixed part other end, the first contact site forms through pressing and bending, it forms protuberance in the bending part punching press, the second contact site comprises bending part, and the first contact site and the second contact site interval separate.

The beneficial effects of the utility model are: by the structural design of electric connector terminal, significantly increase the power of holding that adds of electric connector and banjo connector, avoid loose contact, thereby improve the electric connector of the transmission reliability of electric power or signal.

[embodiment]

Below in conjunction with description of drawings and embodiment the utility model is further specified.

Drawing reference numeral among Fig. 1 to Fig. 5 is: 1 body; 10 reception rooms; 11 grooves; 12 fixed blocks; 2 the first terminals; 20 fixed parts; 21 hold tongue piece; 22 connecting portions 22; 23 first contact sites; Protuberance 231; 24 second contact sites; 241 bending parts; 3 second terminals; 4 shielding casings.

See also Fig. 1, the utility model provides a kind of electric connector, comprise a body 1, be fixedly arranged on described body 1 the first terminal 2 and the second terminal 3, be assembled in the outer shielding casing 4 of body 1.

Consult Fig. 1 and Fig. 2, described body 1 has a reception room 10, in the fixed block 12 that reception room 10 inwalls are provided with plurality of grooves 11 and arrange in groove 11 1 ends, and above-mentioned recessed poor 11 are used for installing the first terminal 2, and fixed block is used for fixedly the first terminal 2.

Consult Fig. 1 to Fig. 4, the connecting portion 22 that holds tongue piece 21, extends in fixed part 20 that the first terminal 2 comprises fixed part 20, arrange with fixed part 20, the first contact site 23 and the second contact site 24 that extend in the fixed part other end, the first contact site 23 forms through pressing and bending, it forms protuberance 231, the second contact sites 24 in the bending part punching press and comprises bending part 241.

In the present embodiment, the first terminal 2 distributes in the mode of second contact site 24 in two the first contact site 23 intervals.

Consult Fig. 4, with the pin connector 5 leading section surfaces of electric connector coupling annular groove 53 is set, in conjunction with Fig. 5, after pin connector 5 inserts electric connector, the protuberance 231 of this connector the first contact site 23 is fastened in the annular groove 53 of pin connector 5, thereby increased the power of holding that adds of connector and pin connector 5, thereby improved the transmission reliability of electric power or signal.

Among another embodiment, the first terminal 2 distributes in the mode of second contact site 24 in the first contact site 23 intervals.

The specific embodiment that is proposed in the detailed description of preferred embodiment is only for being easy to understand the utility model technology contents, be not with the utility model narrow sense be limited to embodiment, all persons that is familiar with the technique carry out other pattern and implement not breaking away under the utility model spirit, the equivalence that all should be considered as this case claim is implemented.
