Abstract
The electric connector includes shielding casing, insulating body and terminals, and the shielding casing is divided into two shielding parts with separate fastening parts for mutual fastening and fixing the insulating body. The second shielding part has one formed earthing unit towards the direction of shielding casing of electronic equipment. The electric connector has simple assembly process and thus low production cost.
Description
The present invention relates to a kind of electric connector, particularly relate to a kind of shielding casing and the integrated electric connector of ground connection holding unit with shielding casing.
Electronics technology is maked rapid progress, and has made present electronic product such as computer or computer auxiliary device light, thin, short, little day by day, and various portable products are widely-used.For making described electronic product reach compact purpose, the spendable configuration space of this electronic product internal electrical components also correspondingly reduces.With the host computer is example, and various electronic building bricks are mostly assembled with surface adhering technology (Surface Mount Technology-SMT) promptly with the stack manner mounting circuit boards in current most popular notes type or pocket computer inside.In the process of installing, the installation pin more than 70 of electric connector is smooth on circuit board 50 with the sheet material of horizontal bending, again with the tin cream 90 of fusion its adhesion (as Fig. 1), but the tin cream 90 of fusion has flowability, and it is too small with the surface area of tin cream 90 adhesions that pin 70 is installed, effective fixing and bear the strength of plug often is shown in Taiwan patent application 82111200.
Secondly, the electric connector volume day by day reduces, therefore can also relatively reduce for the position that the design fixing combines between insulating body and the shielding casing, make the fixing variation, thus electric connector through repeatedly with dock electric connector and plugs after, this shielding casing gets loose on the body that insulate easily, as United States Patent (USP) 4,842,554 and 5, shown in 186, No. 633.
The object of the present invention is to provide a kind of electric connector shielding casing with ground connection holding unit, this ground connection holding unit has a protuberance, and tin cream is strengthened fixing in order to be detained.Second purpose of the present invention is to provide a kind of electric connector shielding casing structure, wherein this shielding casing has a plurality of faces that cover, except that towards the covering the face of butt end, cover face respectively at other buckle district is set, its shielding casing is fastened and the fixed insulation body.
The object of the present invention is achieved like this, be a kind of electric connector,, it is characterized in that in order to be installed on the circuit board with shielding casing, it comprises: insulating body, first holding division that it is provided with butt joint opening, several terminals passage, a plurality of insulation wall and is positioned at the different insulative wall; Several terminals is accommodated in the aforementioned terminal channel; Shielding casing, in order to cover described insulating body, which is provided with a plurality of face and ground connection holding parts of covering, except that covering the face towards the butt joint opening, all the other cover face and are provided with second holding division, described ground connection holding parts ground connection also is retained on electric connector on the circuit board, and different described second holding divisions that cover face are fastened in first corresponding with it on the described insulating body holding division on the described shielding casing.
The advantage of apparatus of the present invention is that its holding unit has a protuberance, and the tin cream of can being detained is strengthened fixing, and a plurality of faces that cover of shielding casing are provided with the buckle district simultaneously, are fixed well with insulating body, is difficult for getting loose, and simplifies assembly program, reduces manufacturing cost.
Describe most preferred embodiment of the present invention in detail below in conjunction with accompanying drawing, in the accompanying drawing:

Fig. 6 is that shielding casing ground connection holding parts of the present invention sticks at the schematic diagram on the circuit board;
Fig. 7 is an electric connector combination stereogram of the present invention.
Please refer to Fig. 2 and Fig. 3, electric connector 10 of the present invention comprises insulating body 20, shielding casing 30 and several terminals 40, insulation wall 21, top insulation wall 22, both sides insulation wall 23 and back insulation wall 24 before wherein insulating body 20 (as shown in Figure 4) comprises, before insulation wall 21 be provided with a butt joint opening 211 near insulation walls 22 positions, top, in order to dock the electric connector (not shown) and docks.Have contact jaw 212 in the butt joint opening 211,, run through back insulation wall 24 in order to take in described terminal 40 in order to realize electrically and mechanical connection that with butt connector contact jaw 212 is provided with several terminals through hole 25.In addition, on top insulation wall 22 and both sides insulation wall 23, be respectively equipped with first holding division 26, respectively in order to fix the face that covers corresponding on the shielding casing 30.
Before mainly comprising, this shielding casing 30 (as shown in Figure 5) covers face 31, face 32 is covered on the top and face 33 is covered in both sides, wherein before cover face 31 and be provided with the through hole 311 that metal stamping goes out, on the butt joint opening 211 that is socketed in insulating body 20, face 32 is covered on the top and face 33 is covered respectively in order to cover top insulation wall 22 corresponding on the insulating body 20 in both sides, both sides insulation wall 23, the top is covered face 32 and both sides and is covered face 33 and respectively be provided with second holding division 34, in order to fix corresponding to first holding division 26 on top insulation wall 22 and the both sides insulation wall 23, so that dispersion fixes point and effectively shielding casing 30 is immobilizated on the insulating body 20.
Shielding casing 30 two side walls 33 are covered the direction extension of face 32 to leaving the top, and ground connection holding parts 35 (as shown in Figure 6) is set towards the horizontal direction bending, in order to be immobilizated on the circuit board 50 with circuit board 50 ground connection and with electric connector 10, cover face 32 directions at ground connection holding parts 35 ends to the top and extend a protuberance 351, in order to the contact area of increase with tin cream 90, the retain strength of 50 of electric connector 10 and circuit boards is increased, therefore, can strengthen fixing between electric connector 10 and the circuit board 50.Electric connector 10 after the present invention's assembling and for example shown in Figure 7 because electric connector 10 volumes reduce, can see that holding division is dispersed to the situation on each plane, because holding division disperses fixing, so effect is more stable.
