Electric connector

Technical field

The utility model relates to a kind of electric connector, refers in particular to a kind ofly to avoid fixation spring tab to stick up metal shell and promote the electric connector of quality.

Background technology

Minimum conducting terminal and the metal shell that includes insulating body, plural number of traditional electric connector.This plural conducting terminal is mounted in this insulating body, and this metal shell then coats this insulating body skin.

For electric connector can firmly be engaged with the electric connector that connects, the metal shell of electric connector that one of therefore can be therein is provided with fixation spring tab.For make simple and easy for the purpose of, use punch press to make this fixation spring tab usually, make this fixation spring tab one end be connected in addition three laminated structures that then disconnect with metal shell.

But microminiaturization along with electric connector, the electric connector inner space is more and more littler, the fixation spring tab of these three disconnections easily causes fixation spring tab to stick up for metal shell in the plug process with the electric connector that docks, not only can't reach fixing effect, also can influence or interfere other contiguous electronic components; In addition, too small fixation spring tab also can't provide enough fixedly elastic force because its length is very short, and remote-effects are to the use and the yield of electric connector.

The utility model content

Main purpose of the present utility model provides a kind of electric connector, can avoid fixation spring tab to stick up metal shell and produces improper the contact with other electronic components and can improve the electric connector of quality.

Secondary objective of the present utility model provides a kind of electric connector, has the electric connector of high fixedly elastic force and firm effect.

Electric connector of the present utility model comprises insulating body, is mounted on a plurality of electric terminals in this insulating body, and coats the metal shell of this insulating body.

This insulating body comprises basic portion and Plug Division, and this basic portion comprises rear surface, front surface, and this Plug Division is connected in the front surface of basic portion, and this rear surface is dug towards front surface and to the Plug Division and is provided with a plurality of terminal holes and is extended with holddown groove in the rear surface; Along two side direction Plug Division directions of the rear surface of basic portion be extended with respectively the portion of picking up the ears and with distance one space, Plug Division, and offer fixing hole towards this space and be connected with this space by the rear surface.

A plurality of electric terminals are mounted in the terminal hole of this insulating body, and respectively this electric terminal comprises elastic portion, holding parts, stabilizers and weld part in regular turn, and interfere fixing by protruding thorn on the holding parts and insulating body.

This metal shell coats this insulating body, comprise upper surface, lower surface and two sides, it surrounds an accommodation space and forms interface, this upper surface is provided with the plurality of fixed shell fragment towards lower surface, this fixation spring tab slightly is strip and comprises first one and second one, this first one and second one's a end is connected with upper surface, its other end then down surface direction extend and be connected.

In an embodiment of the present utility model, the stabilizers of described electric terminal is perpendicular to holding parts and be placed in holddown groove, and this weld part then extends this holddown groove.

In an embodiment of the present utility model, the two sides of described metal shell have snap-latch piece in addition away from an end of this interface, this snap-latch piece is towards extending away from this interface direction and pass space and fixing hole between the portion of picking up the ears and Plug Division, and fastens firmly with insulating body in the rear surface of insulating body through bending.

In an embodiment of the present utility model, contiguous this snap-latch piece place, the two sides of described metal shell is towards extending inserting foot respectively away from this upper surface direction and can directly insert corresponding printed circuit board (PCB) and weld, and weld part that should the plural number electric terminal can electrically connect mutually with printed circuit board (PCB).

The utility model has the advantages that: because first one of this fixation spring tab and an end of second one be connected with upper surface, its other end then down surface direction extend and be connected, therefore do not have the situation generation of sticking up for this metal shell.

Moreover, because first one of this fixation spring tab and second one be connected with upper surface,, provide firm effect if can produce bigger fixedly elastic force during the bigger strain of this fixation spring tab generation.

For making the auditor can understand technical characterictic of the present utility model more, after being specified in conjunction with the accompanying drawings now.
