Embodiment

For the effect making technological means of the present utility model and can reach, can have more complete and clearly disclose, being now described in detail as follows, seeing also the graphic of exposure and figure number:

Fig. 3 is the combination schematic diagram of insulating base frame of the present utility model and clamping device, and together with reference to shown in other each figure, as can be clearly seen from the figure, the utility model is primarily of insulating base frame 1, the clamping device 2 (as Fig. 3) of some terminals 21 held by geometrical clamp, and a pair shell fragment 3 be connected with in substrate 32 left and right sides formed, insulating base frame 1 one end has ringent slot 11, for external lug connector corresponding inserted, on slot 11 inwall, lower both sides have can the terminal groove 12 (as Fig. 4) of accepting terminals 21, and upper in described slot 11 inwall, a caulking groove 13 is formed between the terminal groove 12 of lower both sides, the outer dual-side relatively of insulating base frame 1 is arranged with holddown groove 14 respectively, holddown groove 14 is an inclined-plane and inside contracts gradually to slot 11 direction, to be communicated with slot 11.Clamping device 2 geometrical clamp is held some terminals 21 and is configured in aforementioned terminal groove 12 with correspondence, terminal 21 described in the present embodiment tailors to be shaped with metal stamping to become two row's groups side by side, and the size of the terminal 21 of two row's groups is identical with the dimensions of the terminal of standard USB Type-C type electric connector for socket.Shell fragment 3 extends to form with paired (as Fig. 1) by a sheet of substrate 32 in both sides respectively, namely shell fragment 3 is arranged in pairs, two shell fragments 3 of often pair extend shaping by the both sides of substrate 32 respectively, shell fragment 3 one end is that the clamping part 31 with certain curvature can protrude in slot 11 via the holddown groove 14 of insulating base frame 1 both sides, another in extended Plug Division 33, substrate 32 front end, wherein said substrate 32 more includes some through holes 321, is directly positioned on substrate 32 for during clamping device 2 moldings formed therefrom.

The assembling mode of the present embodiment is by the clamping device 2 of plastic material directly moldings formed therefrom on substrate 32 (as Fig. 2), clamping device 2 is made to be coated on outside substrate 32, clamping device 2 front end and two side positions are exposed to the shell fragment 3 that the Plug Division 33 and substrate 32 both sides that make substrate 32 are paired, again the transplanting of some terminals 21 is formed two row's groups on clamping device 2, wherein, formed two rows group terminal 21 also can in clamping device 2 moldings formed therefrom in substrate 32 time together implement, and make the terminal 21 (as Fig. 3) of the direct coated substrate 32 of clamping device 2 after mold type one-tenth and two rows group, and then the clamping device 2 above-mentioned geometrical clamp being held substrate 32 and terminal 21 is assemblied on insulating base frame 1, the shell fragment 3 of described clamping device 2 both sides can make the clamping part 31 on shell fragment 3 protrude in slot 11 via the holddown groove 14 of insulating base frame 1 at the same time, 33, the Plug Division correspondence of substrate 32 front end is inserted in the caulking groove 13 (as Fig. 4) formed between the terminal groove 12 of insulating base frame 1 inwall, finally can assemble a shielding plate 4 again outside insulating base frame 1 according to the demand of user, namely combination (as Fig. 5) is completed.

Because a pair shell fragment 3 on clamping device 2 and Plug Division 33 are that direct metal punching press is one-body molded, and be directly embedded in clamping device 2, therefore the structure of clamping device 2 is not only enhanced, in time making, more eliminate each element need distinguish the multiple working procedure such as die sinking, assembling, and then reduction cost of manufacture, in addition because the Plug Division 33 that clamping device 2 front end is outstanding is inserted in insulating base frame 1 caulking groove 13, so the Stability Analysis of Structures of insulating base frame 1 also can be increased, therefore being assemblied in terminal 21 on insulating base frame 1 can strong fix, guarantees with stable signal transmission.

In sum, the clamping device of the utility model connector, by the elements such as shell fragment particular design and make overall structure be strengthened firmly, and simplify production process, therefore product can be avoided to have fracture, the generation of damaged situation, have the transmission of maintenance teledata concurrently stablize and reduce cost of manufacture, therefore assembling is no matter functionally, all simple and easy compared with existing structure, convenient, and it is not seen in open use, close the regulation in Patent Law, now propose utility application in accordance with the law, earnestly ask gift quasi patent, real be moral just.

The foregoing is only the schematic embodiment of the utility model, and be not used to limit scope of the present utility model.Any those of ordinary skill in the art, equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should belong to the scope of the utility model protection.
