Abstract
The utility model relates to an electric connector having a shielding casing, which comprises a shielding casing, an insulating body, and a plurality of terminals, wherein, the shielding casing is divided into a first shielding casing and a second shielding casing, the first shielding casing and the second shielding casing are respectively provided with a fastening part by which the first shielding casing and the second shielding casing can be fastened with each other and the insulating body can be fixed, and the second shielding casing is provided with a grounding device with integral forming towards the direction of the shielding shell of electronic device. The utility model simplifies assembly processing and reduces manufacturing cost.
Description
The utility model relates to a kind of electric connector with shielding casing, particularly relates to a kind of shielding casing and the integrated electric connector of ground connection holding unit.
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 purpose of this utility model is to provide a kind of electric connector shielding casing with ground connection holding unit, and this ground connection holding unit has a protuberance, and tin cream is strengthened fixing in order to be detained.Second purpose of the utility model 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 purpose of this utility model is to realize 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 the utility model device 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 utility model in detail below in conjunction with accompanying drawing, in the accompanying drawing:
Fig. 1 installs pin for the known electric connector and is bonded at schematic diagram on the circuit board;
Fig. 2 is the utility model electric connector three-dimensional exploded view, and position, the place ahead of the present utility model is shown;
Fig. 3 is the utility model electric connector three-dimensional exploded view, and position, rear of the present utility model is shown;
Fig. 4 is the stereogram of the utility model electric connector insulating body;
Fig. 5 is the stereogram of the shielding casing of the utility model electric connector;
Fig. 6 is that the utility model shielding casing ground connection holding parts sticks at the schematic diagram on the circuit board;
Fig. 7 is the utility model electric connector combination stereogram.
Please refer to Fig. 2 and Fig. 3, the utility model electric connector 10 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.
