Description

The improvement ground structure of electric connector

Technical field

The utility model is the improvement ground structure about a kind of electric connector, refers to that one can either simplify especially and manufactures component and assembly program, can promote again the improvement ground structure of the electric connector of the ground connection usefulness of electric connector.

Background technology

The connector of universal serial bus (hereinafter referred to as USB) specification is in daily life uses, it is one of transport interface interface of extensive use the most, because facilitating of USB interface is easy-to-use, size is little and cost is reasonable, the trace of the USB that is therefore all seen everywhere at each different operating field domain.

No matter be the notebook computer of core entertainment device as TV, individual of family, smart mobile phone, board device or work active computer, the printer of office, and even the multi-media communication entertainment systems of automobile, is all dependent on USB connector often to carry out the task of data transmission.

In order to the more universal application of USB on different device is powered, and easy to carry and more frivolous electronic multimedia product is provided, reduce the situation occurring because of USB direction of insertion or wiring anisotropy to transmit, brand-new universal serial bus Type C just arises at the historic moment simultaneously.USB formulates the world ANSI (USB-IF) in announcing the standard criterion that this key name is USB Type C interface a few days ago, be intended to by the electric power transfer amount up to 100 watts, various device is allowed all to meet power demands by an independent USB cable, make it shorten the advantage in device charging interval, more can optimize the convenience of mobile applications.

In addition, the brand-new ultrathin design of various equipment will be supported in USB Type C interface, from mobile phone, panel computer, two-in-one product, notebook computer to the equipment of desktop computer and other numerous more specifically purposes.

This adopts the slim interface of industry new standard can data transmission, electric power and video signal, to people be become in conjunction with the unique interface needed for various device transmission, due to synchronously rolling up of data transmission amount, in use may produce corresponding electromagnetic radiation, so that the normal operation of interference other electron component, in view of this, industry generally all can reduce the generation of electromagnetic interference (EMI) with earthing mode.

Only, USB Type C interface due to its conducting terminal quantity more, and volume is also along with diminishing, in limited space, how to overcome the generation of electromagnetic interference (EMI), will be that this product needs the problem overcome badly.

In order to solve the problem, a ground lug structure is provided with respectively between USB TYPE C interface system's design lines terminal adapter and plate terminal adapter, and this line-end connector and plate terminal adapter are when mutually docking, the elastic arm of this line-end connector ground strip then can clamp with plate terminal adapter, uses eliminating electromagnetic interference; Refer to No. M491281st, TaiWan, China new patent, it discloses a kind of connector volume grounding structure improvement, wherein this ground strip and elasticity grounding fastener arm thereof are a plate-like structure, specifically adopt blanking type technique, only, when the continuous reciprocating elastic distortion of elasticity grounding fastener arm, because the strong point support force of its strain is not enough, therefore easily there is the situation of elastic fatigue, and then cause and cannot be connected with the mutual buckle of the ground strip of plate terminal adapter, cause the situation of the stability deficiency getting rid of electromagnetic interference to occur.

As can be seen here, above-mentioned existing structure still has many disappearances, a real non-kindhearted designer, and is urgently improved.

Inventor in view of above-mentioned existing structure every shortcoming of deriving, be urgently think to be improved innovation, and after taking great pains to attain one's goal for many years and concentrating on studies, finally successfully researched and developed the improvement ground structure of this part electric connector.

In order to achieve the above object, the utility model provides a kind of improvement ground structure of electric connector, and it includes:

One first insulating body;

One second insulating body, fits with mutual corresponding assembling of the first insulating body;

One ground strip, this ground strip includes one and is placed in flat part between the first insulating body and the second insulating body, and these both sides, flat part rear end are extended with a weld part towards direction, bottom; These flat part both sides are then bent with an elastic arm towards front end, and be then formed with the kink that is Curved Continuous folded structure between this elastic arm and flat part, this kink is as the strain fulcrum of elastic arm.

In an embodiment of the present utility model, wherein this elastic arm front end is then extended with a clamping part towards inner edge.

In an embodiment of the present utility model, wherein this kink also can be bent to U-shaped or reverse U shape structure from flat part continuously.

In an embodiment of the present utility model, be wherein provided with the first conducting terminal in this first insulating body; Then be provided with the second conducting terminal in second insulating body, this first conducting terminal and the second conducting terminal are in electrical contact with butt connector.

In an embodiment of the present utility model, wherein the weld part of this ground strip end is then for being welded on circuit board, so as to being drained on circuit board by high frequency noise.

In an embodiment of the present utility model, its can sheathed one insulation external member in and mutually assemble, be then connected with a shielding casing is sheathed again after assembling, make it meet USB3.1 specification.

The improvement ground structure beneficial effect of electric connector of the present utility model is:

The utility model is arranged by the kink of continuously bending, oppositely extends bending upward after flat part extends again, and making it form one can, for the strong point of strain repeatedly, provide the reciprocating elastic distortion of elastic arm to use; Elastic arm of the present utility model forms from the kink extension of bending continuously, and therefore its life-span of being reciprocally out of shape is increased, and effectively improves its useful life.
