Description

The ground structure of gland-type connector

Technical field

The utility model is a kind of electric connector, refers to a kind of gland-type, ground structure with the connector docked with objects such as FPC or FFC especially.

Background technology

Electric connector is a kind of electronic components, 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 had and is 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 with 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, so as to transmitting the signal that it passes through.

In relevant prior art document, disclosed by TaiWan, China I438972 patent, be exactly that a kind of electric connector that connect, particularly the prior art corresponding to FFC also discuss and contact with the earth terminal of FFC, the noise filtering by ground connection diversion mode some can disturbed.From then on Figure 13 of case can have a clear understanding of, and this connector is that the metal assembly 7 being installed in both sides contacts so as to drainage interference noise wherein with the earth terminal 3 on the flexible flat cable FFC4 inserted in connector; Wherein the structure of this metal assembly 7 is disclosed by Figure 11, include a ground contact 10 and a leaf spring 39, the contact generating unit reverse with it, and this leaf spring 39 is one-body molded with ground contact 10, when flexible flat cable FFC4 is inserted in therebetween, between its earth terminal 3 and this ground contact 10, produce a contact.

Although by the prior art of above taking off, can help flexible flat cable FFC4 after engaging with this connector, except the electronic signal on conducting FFC, also can ground connection mode will interference noise filtering, but, metal assembly 7 structure of this case design is too complicated, will produce certain puzzlement on applying, and qualification rate is not high to be increased the cost causing manufacturing; In addition, carry out ground connection contact by the mode of this clamping, prerequisite is that the insertion point (between ground contact 10 and leaf spring 39) of flexible flat cable FFC4 is very accurate, otherwise the effect of ground connection is probably affected.

Utility model content

The utility model proposes a kind of ground structure of gland-type connector especially, directly contacted with the earth terminal of the FPC/FFC inserted in connector by the metal ear buckles assembly that connector configures, both getting rid of, carrying out the noise jamming in signal transduction process, the quality that signal is transmitted is more stable; Particularly the structure of this earclip simple, be easy to apply, compared to prior art, can help the manufacturing cost reducing connector, be main purpose of the present utility model.

1, for realizing utility model object, the utility model provides a kind of ground structure of gland-type connector, include an insulating body, multiple conducting terminal, a gland and two earclips, the plurality of conducting terminal is fixed in insulating body, two ends, the vertical court of insulating body axis are respectively extended with a guide arm away from the direction of this insulating body, two guide arms and insulating body surround the plug space locating formation one object, and insulating body is connected with a base with the bottom surface of two guide arms, on the base, be adjacent to the block holding part that two guide arm places respectively have a projection, two these earclips are distinctly arranged in two guide arms, this earclip is a kind of metal assembly, this earclip at least has a main part, a junction and a grounding parts, described main part is on the connectors affixed, the wiring board of this connecting portion and connector outside is connected and fixed, this grounding parts then contacts with the earth terminal of the object inserted in connector, in addition, this grounding parts includes a leaf spring and a contact site, one end of this leaf spring is connected with a fishplate bar, the side of this fishplate bar is connected to the upper limb of main part, this contact site is then connected to the free end of leaf spring, there is between this leaf spring and this fishplate bar a turning point, this leaf spring is made to have the base flexibly pointing to connector by this turning point.

Wherein, two guide arms coordinate the structure of installing earclip symmetrical each other, in this guide arm away from the end of insulating body, there is a mounting groove that is open, that extend towards insulating body direction, the bottom of this mounting groove has a perforation to run through guide arm, this mounting groove is extended with a clip slot towards plug direction in space local, and this clip slot is communicated with this plug space; The main part of this earclip is inserted in mounting groove, and this connecting portion exposes in perforation, and the fishplate bar of this earclip then exposes to the plug space of connector by this clip slot.

Wherein, this block holding part has the oblique surface of a rising.

Wherein, the opposite end of the fishplate bar connection leaf spring of this earclip has the baffle plate of a tilting.

Wherein, the main part of this earclip is also extended with an inserted terminal, and the surface of this inserted terminal has spinal plate.

Wherein, this gland has a lid, this lid covers plug spatially along the inner side of two guide arms, the both sides of one ora terminalis axis of this lid respectively have a rotating shaft outwardly, the inner side of two guide arms then respectively has the opposed tank of a horizontal direction, two described rotating shafts are placed in two tanks and locate, and this lid spatially can lift in plug rotatably and to open or closed.

The advantage that the utility model has is:

One, compared to prior art, the structure of metal ear buckles is more simple and be easy to apply, and can help the manufacturing cost reducing connector.

Two, block holding part is designed with the oblique surface of rising, is more conducive to pass through and can not be hindered when FPC/FFC imports connector.

Three, earclip is when assembling, and punctures being fixed in mounting groove that guide arm makes that it more can be stable not easily hauled out by the spinal plate on inserted terminal.

Four, the baffle design on earclip, can stop that main part moves in mounting groove, and this anchor point namely determines the position of the contact site of leaf spring free end, and this contact site can correctly be contacted with the earth terminal on FPC/FFC.

Five, import at FPC/FFC in the process of connector, pass through between the fishplate bar and base of earclip, in other words, except borrowing the contained guiding in the two left and right directions of guide arm, more there is the upper and lower position between fishplate bar and base to guide, make that this FPC/FFC can to enter into plug space corresponding with the multiple conducting terminals on insulating body and contact in more accurate position.

Six, pass in the clip slot of the fishplate bar of earclip in guide arm, leaf spring can be made to acquire support when elastic reaction, in other words, the clip slot of guide arm can help fishplate bar not yielding.
