Abstract
The present invention relates to an electric connector at least comprising an insulating casing, a metal casing and a plurality of terminals, wherein the insulating casing is provided with a plurality of passages for accommodating the terminals; the metal casing comprises a front casing and a rear casing; at least one wall face of the rear casing is provided with a fixing part which is used for combining the insulating casing and the metal casing and limiting the displacement of the insulating casing in the horizontal direction; the side edge of the rear casing is provided with a clamping device which is used for clamping the insulating casing and limiting the displacement of the insulating casing in the vertical direction.
Description
It is firm to the present invention relates to a kind of structure, and the good and easy electric connector of welding of shielding is meant a kind of wire and cable connector that meets the universal serial bus standard especially.
In the comprehensive development trend of current information industry, universal serial bus (Universal SerialBus) connector will replace D connector and the MINI din connector that usefulness is gone in most of output.Apply for the 84104611st, 84113371,84218007, No. 85202862 and No. 533794 disclosed universal serial bus connector of U.S. Patent application according to the 1.0th edition designed Taiwan of universal serial bus connector industry unified specification, and No. the 81217896th, 82109498, Taiwan patent application and United States Patent (USP) are announced disclosed electric connector the 5017156th, 5013262,5073130, No. 5221212, though the connector with firm clamping structure all is provided, when using and make, still has following shortcoming:
1, easily cause electric wire and terminal to get loose because of pullled by external force;
2, because of plug-in connector makes the metal shell deflection deformation, thus produce the gap with insulation shell can't driving fit, influence the normal use of connector;
3, in the processing that connects electric component and terminal, instrument is difficult for entering machining area and increases the connector manufacture difficulty.
The object of the present invention is to provide a kind of structure firm, easy to manufacture and shield good electric connector.
The object of the present invention is achieved like this, and a kind of electric connector promptly is provided, and which comprises at least: an insulation shell, a metal shell and several terminals; This insulation shell is provided with several passages of accommodating described terminal; This metal shell comprises procapsid and back casing, at at least one wall of described housing the fixed part that combines and limit the displacement of described insulation shell along continuous straight runs for described insulation shell with metal shell is set, and the buckle insulation shell is set and limits its vertically bayonet unit of displacement at described back casing lateral margin.
The advantage of apparatus of the present invention is that its welding is assembled facility easily, and connection is stable, and conducting is good, and shielding reliably.
Below in conjunction with accompanying drawing, embodiments of the invention are described, wherein:
Fig. 1 is an electric connector stereogram of the present invention;
Fig. 2 is an electric connector three-dimensional exploded view of the present invention;
Fig. 3 is an electric connector insulation shell stereogram of the present invention;
Fig. 4 is a metallic shell of electric connector body stereogram of the present invention.
For the benefit of explanation in conjunction with a preferred embodiment of the present invention, sees also Fig. 1 and Fig. 2, and this electric connector comprises insulation shell 20, metal shell 30, metal top cover 40 and terminal 50.Shown in Fig. 2,3, body 21 tops of insulation shell 20 are provided with two projections 211, and in order to buckle metal shell 30, outer rim both sides, top respectively are provided with the stop section 212 of a location usefulness in addition; Body 21 front ends are provided with a contact site that is connected with butt connector 22, and its leading edge is provided with first accepting groove 221, in order to the claw 312 of accommodating metal shell 30.Extend an electric connection part 23 in body 21 rear ends, terminal 50 and other electric component are (as electric wire, do not show) join at this, and on insulation shell 20, be provided with at least one passage 231 and run through wherein to accommodate terminal 50, one second accepting groove 232 that respectively sets to the concave in both sides, electric connection part 23 rear end is with the ear 332 of accommodating metal shell 30.
And for example shown in Fig. 2,4, this metal shell 30 is by the moulding of metal tablet integrated punching.This metal shell 30 is divided into the procapsid 31 that coats aforementioned dielectric housing contact site 22 and part body 21, with the back casing 32 of protection electric connection part 23.Procapsid 31 diapires 311 front ends upwards inwardly are convexly equipped with two claws 312, be housed in first accepting groove 221 of aforementioned dielectric housing 20 contact sites 22, prevent that the electric connector plug from making contact site 22 front ends and procapsid 31 gap occur, roof 313 rear ends extend a protuberance 314 backward, which is provided with at least one breach 315, when insulation shell 20 combines with metal shell 30, breach 315 on projection 211 buckle procapsids 31 protuberances 314 of body 21, and utilize the elasticity of protuberance 314 reduce metal shell 30 in conjunction with the time deflection that produced.Diapire 321 convex being provided with of back casing 32 are the fixed part 322 of two rib shape projectioies, and in order to hold out against insulation shell 20 rear ends, restriction insulation shell 20 combines back horizontal direction displacement with metal shell 30.The two side 33 that procapsid 31 and back casing are 32 respectively is provided with a depressed part 331, welding gun enters electric connection part 23 easily with terminal 50 and electric wire welding when making assembling, other connects processing method such as IDC, clip etc., also can make tool to enter machining area easily and enter processing.Simultaneously, 33 respectively establish an ear 332 in the two side, after insulation shell is inserted metal shell, bending ear 332 is snapped in second accepting groove 232, with vertically displacement after limiting insulation shell 20 and metal shell 30 combining, and can prevent that electric component and terminal 50 from getting loose because of plug-in connector.
Therefore, the above-mentioned good clamping structure of mat, metal shell 30 deflections in the time of can effectively reducing assembling, and prevent to produce the gap between metal shell 30 and the insulation shell 20, avoid electric wire and terminal 50 to get loose.Simultaneously, be provided with the depressed part 331 on 32 two sides 33 of procapsid 31 and back casing, can effectively reduce the welding difficulty.
