Description

Rear pressing cover formula connector

Technical field

The utility model relates to a kind of electric connector, refers to a kind of rear pressing cover formula connector especially.

Background technology

Electric connector is a kind of electronics zero element, is extensively used in various electronic product, by the electric connection of electric connector in equipment or device, is transmitted and link up to assist signal to each other.

The connected mode of electric connector and signal source, is generally undertaken by modes such as welding, clamping or crimping.For example, with being connected with cable, the electric connector of signal transmission, terminal group normally by welding, and then is contained in this electric connector and locates by the connected mode of its built-in terminal and each cable.As for flexible printed wiring (FlexiblePrintCircuit, or flexible flat cable (FlexibleFlatCable FPC), FFC) electric connector connected, the terminal group being then normally designed with clip is in electrical connectors docked with FPC or FFC of this tabular or sheet, to transmit the signal that it passes through.

In relevant prior art document, TaiWan, China is announced M438715 patent and disclosed, and a kind ofly exactly discusses the electric connector that connect corresponding to FPC.Can find from this case: this connector produces chucking power to the FPC inserted after driving the distortion of clip terminal by a rear pressing cover, with fix position that this FPC inserts and with this clip termination contact and carry out Signal transmissions; Its problem produced is: metal terminal easily causes tired after long-time distortion uses, make not enough to the crystallized ability of FPC and produce the phenomenon that gets loose, if be subject to some external force interference improperly to depart from from connector, or cause the loose contact of connector and FPC, the quality of this connector signal transmission is had a strong impact on.

Moreover, as shown in Figure 1, existing FPC1 is in order to strengthen the ability be fixed in the connectors, a breach 10 can be designed with in its both sides location is provided, and in order to mate the breach 10 of this location, usually can set up the fixture block of a projection with its contraposition place in the connectors, prevent FPC1 from deviating from from connector or abnormal displacement by the interference of this fixture block and this breach 10.But with regard to the technology contents that this rear pressing cover formula of similar bulletin M438715 patent connector provides, but cannot import and coordinate the Position Design of FPC breach 10 formula completely, because this fixture block can directly hinder the path inserting this connector to FPC.

Moreover, comprise the connector construction that above-mentioned bulletin M438715 patent and relevant prior art document are discussed, do not have corresponding FPC/FFC to provide grounding function more, the interference making it cannot filter some noises in the process of Signal transmissions to cause.

Utility model content

In view of this, the purpose of this utility model is to provide a kind of rear pressing cover formula connector.

To achieve the above object, the utility model provides a kind of rear pressing cover formula connector, comprising:

One insulating body, this insulating body has multiple slot, its forward has a frame mouth, the two ends of its transverse direction are respectively extended with a guide arm towards the vertical direction away from this frame mouth, this two guide arm and this insulating body surround the plug space locating formation one object, the inner side of this two guide arm respectively has the opposed tank of a horizontal direction, and this insulating body is connected with a base with the bottom surface of this two guide arm, and on this base, the position of each slot corresponding has and this guide arm location notch in the same way;

Multiple conducting terminal, each conducting terminal respectively has a contact site and a conducting portion, and this contact site is extend into this plug space and located by this slot and this location notch, and the signal source that this conducting portion then stretches out this connector outer and outside connects;

One gland, this gland has a lid, and this lid is covered in this plug spatially, and the both sides of one ora terminalis axis respectively have a rotating shaft outwardly, this two rotating shaft be placed in this two guide arm tank in and locate;

The inner side of this guide arm is more connected with an earclip, and this earclip has an inserted terminal and a link, and this inserted terminal extend into this insulating body and fixes, and this link then stretches out from base; This earclip also has one day this plug direction in space hang down into shell fragment.

Preferably, wherein the free end of this shell fragment has the support of an arc.

Preferably, wherein this shell fragment compresses and is contacted with the earth terminal of this object.

Preferably, wherein this lid is also provided with at least one towards the outstanding fixture block of plug direction in space, this fixture block and lid interlock also extend into when lid closes in this plug space.

The utility model has following beneficial effect:

One, by the fixture block with lid interlock, make the connector of this rear pressing cover formula can mate the locating notch of FPC, and really can play the effect of its anticreep;

Two, by the design of earclip, except helping, connector is stable is fixed in outside, it hangs down into the shell fragment in plug space, make FPC in the stroke inserting connector, the support that can touch shell fragment forces it to be out of shape, and the power oppositely formed one compacting of this FPC, FPC more stably can be located after completing the contact action with conducting terminal, and really reach the ability of its Signal transmissions; And, can help noise ground drainage after this shell fragment contacts with object and go out, to reduce the interference of signal.
