Abstract

The utility model discloses an electric connector, including base, shell fragment terminal, protecgulum, still terminal, central needle. It has the jack to open on the base, the protecgulum joint is at the base front end, open on the protecgulum have with jack counterpoint complex hole, the hole of protecgulum is the ring -type and has laid a plurality of contact pieces in advance, and the contact piece stretches into in the jack in advance, the shell fragment terminal is established in the base, and it is put the shell fragment and is arranged in the wing shell fragment of putting the shell fragment both sides in being, shell fragment terminal and protecgulum electric connection, the still terminal inserts the base and puts the shell fragment cooperation of counterpointing in with. The utility model discloses utilize in advance the contact piece to realize contact in advance and realize the reposition of redundant personnel to the shell fragment terminal, increase the electrical contact area, reduce impedance, temperature rise, effectively improve electric connector's performance and safety in utilization.

Description

A kind of electric connector

Technical field

The utility model relates to a kind of electric connector, a kind of impedance is specifically low, temperature rise slowly and not easily produce pyrophoric electric connector.

Background technology

Along with the development of economic society, each electron-like, electric equipment are widely used, electronics, electric equipment when carrying out work, need to use electric connector coordinate with Electric plug with shutter realize being electrically connected, delivery of electrical energy.

Electric connector, as electric equipment products and accessory requisite when being electrically connected, in people's daily life, uses very extensive, the huge market demand, plays an important role to the normal operation of electric equipment products.

Existing electric connector, because internal structure limit, when Electric plug with shutter is connected with electric connector, area in electrical contact is little, impedance is large, temperature rise is fast and plug moment easily produce spark, there is certain use hidden danger.

Utility model content

The purpose of this utility model overcomes the deficiency existing for existing electric connector, provide that a kind of impedance is low, temperature rise slowly and not easily produce pyrophoric electric connector.

For achieving the above object, the technical scheme that the utility model adopts is:

A kind of electric connector, comprises pedestal, shell fragment terminal, protecgulum, still terminal, center pin.

Pedestal has jack;

Protecgulum is connected to pedestal front end, protecgulum has the hole coordinated with jack contraposition;

The hole of protecgulum is laid with some pre-terminated contacts in the form of a ring, and pre-terminated contact stretches in jack;

Shell fragment terminal is located in pedestal, and it comprises in mid-shell fragment and is positioned at the wing shell fragment of mid-shell fragment both sides;

Shell fragment terminal and protecgulum are electrically connected;

Still terminal insertion pedestal coordinates with mid-shell fragment contraposition;

Center pin inserts in the jack in pedestal.

Further, protecgulum is made up of conducting metal.

Further, still terminal is made up of conducting metal.

Further, center pin is made up of conducting metal.

When the utility model is implemented, still terminal and mid-spring are in closure state, when Electric plug with shutter inserts in jack, pre-terminated contact and Electric plug with shutter is utilized to carry out pre-contact, when Electric plug with shutter inserts further, Electric plug with shutter compresses mid-spring, center pin and wing spring and contacts cooperation with it, realizes being electrically connected.

The utility model utilizes pre-terminated contact to realize pre-contact and realizes the shunting to shell fragment terminal, increases area in electrical contact, reduces impedance, temperature rise, effectively improves serviceability and the safety in utilization of electric connector.

Embodiment

Further understanding for convenience of doing the utility model, now enumerating embodiment by reference to the accompanying drawings, the utility model is further described.

Embodiment:

As Figure 1-5, the utility model comprises pedestal 1, shell fragment terminal 4, protecgulum 2, still terminal 7, center pin 3.

Pedestal 1 has jack;

Protecgulum 2 is connected to pedestal 1 front end, protecgulum 2 has the hole coordinated with jack contraposition;

The hole of protecgulum 2 is laid with some pre-terminated contacts 8 in the form of a ring, and pre-terminated contact 8 stretches in jack;

Shell fragment terminal 4 is located in pedestal 1, and it comprises in mid-shell fragment 5 and is positioned at the wing shell fragment 6 of mid-shell fragment 5 both sides;

Shell fragment terminal 4 and protecgulum 2 are electrically connected;

Still terminal 7 inserts pedestal 1 and coordinates with the contraposition of mid-shell fragment 5;

Center pin 3 inserts in the jack in pedestal 1.

Above embodiment is optimal enforcement of the present utility model example, not any pro forma restriction is done to the utility model, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be revised as the Equivalent embodiments of equivalent variations, but any amendment allly do not depart from the utility model technical method principle and content, doing according to technical spirit of the present utility model to above embodiment, equivalent variations and correction, all still belong in the scope of the utility model technical method.
