Description

Card connector

Technical field

The utility model relates to a kind of card connector, being particularly related to a kind of Subscriber Identity Module (subscriberidentity module) that supplies is inserted in wherein, and can be arranged on the circuit board, make the Subscriber Identity Module that is inserted in wherein reach the User Recognition card connector that telecommunications is connected with circuit board.

Background technology

Along with developing rapidly of science and technology, mobile phone becomes necessary tool in people's communication, the set circuit board of predetermined position of general mobile phone casing can weld establishes a User Recognition card connector, this connector is made up of insulating body and plurality of terminals, after its assembling is finished, nationality by the weld part of terminal again with the casing of mobile phone in the circuit board welding fixing, and then nationality does telecommunication contact by the corresponding position with Subscriber Identity Module of the top arc portion of the terminal that protrudes from this insulating body, yet there is following shortcoming in this type of connector:

At first, must in the casing of mobile phone, establish a movable positioning plate or guide mechanism in addition again, can utilize this movable positioning plate or guide mechanism that Subscriber Identity Module is located when making Subscriber Identity Module and termination contact, thus, the structure of casing is comparatively complicated and easily waste the manpower and the man-hour of assembly.

Secondly because arc portion of each terminal stretches out the insulating body upper surface, therefore when carry out the assembly operation, cause friction or dogging to produce to be out of shape thereby mechanism's region of interest is run at terminal curved arc position easily or get loose with aforementioned mechanism.

Summary of the invention

The purpose of this utility model is to provide a kind of User Recognition card connector, when its each terminal nationality establish by the weldering of the circuit board of welding foot and mobile phone fixing after, do not need in the casing of this mobile phone, to add movable positioning plate in addition, can directly utilize space between its bayonet unit and the insulating body that the intercalation of Subscriber Identity Module is provided, with the structure of simplifying this casing and the assembly operation of this connector and casing.

Another purpose of the present utility model is to provide a kind of User Recognition card connector; when the upper end of going up the contact curved arc of its each terminal with the suitable gap of the medial surface maintenance of bayonet unit and be positioned at the below of bayonet unit; thereby can protect terminal when assembling operation, can not caused terminal distortion or get loose, thereby also can avoid going up the touching that the contact curved arc do not expected or colluding card and produce and be out of shape or phenomenon such as get loose of terminal simultaneously in use by collision. the contact of guaranteeing terminal is good.

For achieving the above object, the utility model provides a kind of card connector, this card connector is by insulating body, plurality of terminals, and bayonet unit is formed, it is characterized in that this insulating body, its inside is provided with a plurality of terminal slots, and be provided with location notch in its both sides, this terminal is to be inserted in the terminal slots by the side of insulating body, and this bayonet unit is provided with a spacer, when bayonet unit is vertically inserted insulating body, can form fixingly with the location notch of insulating body, can supply the ccontaining space of SIM card thereby form one at the inner surface of the upper surface of insulating body and bayonet unit.

The utlity model has following beneficial effect: directly utilize space between its bayonet unit and the insulating body that the intercalation of Subscriber Identity Module is provided; with the structure of simplifying this casing and the assembly operation of this connector and casing; can protect terminal when assembling operation, can not caused terminal distortion or get loose by collision; also can avoid simultaneously going up the touching that the contact curved arc do not expected or colluding card and produce and be out of shape or phenomenon such as get loose of terminal in use, thereby the contact of guaranteeing terminal is good.

Embodiment

For reaching above-mentioned purpose and effect, the existing drawing with regard to preferred embodiment of the present utility model described in detail so that technological means and the structure thereof that everybody understands the utility model fully and is adopted.

Fig. 1, Fig. 2 are respectively three-dimensional exploded view of the present utility model and stereo appearance figure, find out that by knowing among the figure User Recognition card connector of the present utility model is made up of bayonet unit, plurality of terminals and insulating body, wherein terminal is inserted by the side of insulating body, and bayonet unit then from top to bottom inserts with insulating body and interferes.

Details are as follows with regard to the primary structure feature of this case below:

Fig. 3 and Fig. 4 are respectively the face upwarding stereogram and the top perspective view of insulating body. and insulating body 3 as shown in Figure 3 and Figure 4, its both sides offer three terminal slots that do not connect 35 respectively, can insert for six terminals, Fig. 6 is the stereogram of terminal, stuck point 23 interferes after assembling with insulating body interpolation slit 34, be used for fixing terminal, terminal scolding tin pin 25 is fixed with circuit board soldering tin, the terminal insulating body 3 back projections 21 of packing into are buckled in enlarging 33 the insides, so the terminal front end can not be drawn out the insulating body face because of external force factor, and then terminal distortion when causing the Subscriber Identity Module card to insert, even terminal fracture. terminal bottom surface 26 is buckled in down in the enlarging 36, thereby the bottom surface of control terminal in vertical direction, contact curved arc 22 makes terminal to form good the contact with the Subscriber Identity Module card on the terminal, thereby form the telecommunication contact, the U-shaped curved arc 24 of terminal makes terminal have enough elastic force, guarantees that it is good with contacting of Subscriber Identity Module and insulating body.

The direction of insertion of bayonet unit 1 is vertical with the upper surface of insulating body 3. as shown in Figure 5, spacer 12 vertical insertions in the location notch 32, as Fig. 7, interference stuck point 122 shown in Figure 8 has been fixed spacer 12 on vertical direction and left and right directions, interfere salient point 121 on fore-and-aft direction, to fix spacer. four bit-avoiding slots that run through up and down 31 have been avoided the scolding tin pin 11 of bayonet unit, the design of mounting hole 13 has increased the tin absorbing property of scolding tin pin, the mode that bayonet unit 1 inserts is inserted from the side in the conventional art and is more conducive to automated production in enormous quantities, and avoided effectively that the insertion owing to bayonet unit makes insulating body produce the soft flocks phenomenon in the conventional art. gap between the inner surface of bayonet unit 1 and insulating body 3 surfaces just can be gone into for the Subscriber Identity Module intercalation, makes this Subscriber Identity Module to contact curved arc 22 formation telecommunications with going up of each terminal that stretches out insulation colloid upper surface and contacts.

Above-mentioned detailed description is just at a kind of preferable possible embodiments explanation of the utility model, but this embodiment is not in order to limit claim of the present utility model, the equal variation that other is finished under the shown skill spirit of the utility model or modify change all should be included in the claim that the utility model contains.In sum, the utility model really meets the regulation of Patent Law, and filing an application in the whence in accordance with the law, expects early to grant a patent.
