Description

The shield member of electric connector

The utility model relates to a kind of shield member, is meant a kind of shield member that earthing device and one are coated on electric connector that has especially.

The shield member relevant with the utility model, be a kind of shield member that is used for microminiature connector (MINI DINCONNECTOR), this kind shield member is because the electric connector that is shielded is higher to request signal transmission, and is therefore also higher to the requirement that prevents electromagnetism and electrostatic interference.So, this type of shield member except that have with earthing device that circuit board is communicated with, also be provided with the earthing device that can be in communication with the outside in addition.Relevant design can be with reference to No. the 77208107th, 78204790,80104898,80208342,80211820,82111200,82201874,84201441, Taiwan patent application, and United States Patent (USP) the 4th, 637,669,4,842,554,4,842,555,4,908,335,4,995,819,5,017,158 and 5,186, shown in No. 633.

But set earthing device on the above-mentioned existing shield member all is the end screw lock of mat one bolt with a ground strip, and the rubber-like free end contacts the formation grounded circuit with the connector or the computer chassis of butt joint.Thereby not only increase the step of assembling, and because of fixing in the screw lock mode, the free-ended elasticity of this ground strip is not very desirable, so the influence and the effect that contacts after butt connector is pegged graft consequently often cause loose contact and signal transmitted be affected.

Loaded down with trivial details and influence the shortcoming that signal transmits with the earthing device assembling for solving existing shield member, the purpose of this utility model is to provide a kind of manufacturing easy to assembly, and the good shield member of ground connection.

To achieve these goals, the shield member of electric connector of the present utility model comprises: a plug surface has spliced eye on it; Left and right and top surface, be close to described plug surface and with the common receiving space that forms of described plug surface; At least one grounding leg is located at aforementioned arbitrary surface and is pegged graft with circuit board; And an earthing device, by extending and be positioned at described plug surface the place ahead in aforementioned arbitrary surface.

The shield member of electric connector provided by the utility model is provided with earthing device integratedly, but not only the simple inlay card mode of mat engages, and also for its earthing device provides excellent contact elasticity, and its assembling is simple and direct, ground connection is reliable.

Now in conjunction with the accompanying drawings, preferred embodiment of the present utility model is described in detail as follows:

Fig. 1 is the stereogram of shield member first embodiment of the utility model electric connector.

Fig. 2 is the stereogram of the utility model first embodiment opposite side.

Fig. 3 is the front perspective view of the shield member of the utility model electric connector.

Fig. 4 A, 4B are the stereogram of the utility model electric connector shield member second embodiment different angles.

See also Fig. 1 to Fig. 3, the shield member 1 of the utility model electric connector is the one bending and molding, have plug surface 10, about

surface

11 and 12, top surface 13 and grounding leg 14, and earthing device 15 etc., wherein have spliced eye 101 (as shown in Figure 3) on the plug surface 10 as the preformed hole that butt joint is provided.And extending earthing device 15 in the apical margin one of plug surface 10, this earthing device 15 is a lappet that tilts, and which is provided with jack 151, it is corresponding with the spliced eye 101 of plug surface 10, and its nearly centre bloats, and forms convex arc shaped slightly, can make the contact better effects if of butt joint.In addition, about surface the 11, the 12nd, extend symmetrical two sides by the dual-side of plug surface 10, and with plug surface 10 and the top surface 13 common receiving spaces that form, be used to accommodate the insulation shell (not shown) of electric connector.And,

surface

11,12 and top surface 13 are provided with to ending body 2 about this, should support end body 2 and on each surface, go out one and inwardly and to what spliced eye 101 tilted support sheet 20, when mat should support sheet 20 insulation shell of electric connector is assembled, have urgent and effect retaining.In addition, this top surface 13 extends bending again by the apical margin on

right surface

12,11 of its free end and left surfaces are provided with coupling apparatus 3 (seeing also Fig. 2), this coupling apparatus 3 is to extend a tongue piece 30 at top surface 13 free ends, and on tongue piece 30, being provided with a retaining body 301, this retaining body 301 is to go out an inside hangnail sheet on the face of tongue piece 30.And on left surface 11, establish a caulking groove 31, this caulking groove 31 is that 11 upper limb is gone out the concave face 312 with line of rabbet joint 311 in the left surface, this line of rabbet joint 311 is planted for the tongue piece 30 of top surface 13, and the concave face 312 bottom ora terminalis of caulking groove 31 supply the hangnail sheet 301 of tongue piece 30 only to support, and top surface 13 firmly can be combined with left surface 11 like this.In addition, the inner peripheral at spliced eye 101 also is formed with as jagged contact chip 102, with the effect of enhanced grounding.

As mentioned above, shield member 1 integrated punching moulding of the present utility model is again through suitably bending, and be combined as a whole in the inlay card mode, make that not only manufacturing is easy to assembly, and this ground connection lappet of mat 15 tilts and the design that bloats, good contact effect can be provided, thereby make the grounded circuit of butt connector reliable, the good effect that prevents electromagnetism and electrostatic interference is provided.

In addition, see also Fig. 4 A, 4B, it is second embodiment of the present utility model, among this embodiment with the difference of aforementioned first embodiment be this ground connection lappet 15 ', be by top surface 13 ' extend, rather than from plug surface 10 ' the end extend, assembling is convenient also to provide the good earth effect but make.
