Description

Clamshell Connector

technical field

The utility model relates to a flip-top connector, in particular to a flip-top connector capable of stably clamping and positioning a flexible cable, avoiding shaking of the flip cover and improving the stability of the flip cover.

Background technique

The cable is a data cable made of PET insulating material and extremely thin tinned flat core wire or round core wire. It has the advantages of low price, thin thickness, bending and folding, and is easy to form an electromagnetic shield. (EMI) characteristics have been widely used in the connection between moving parts and motherboards among many related electrical products.

As shown in Figure 1, it is a structural cross-sectional view of a conventional cable connector. This conventional cable connector is provided with a crimping groove 13 for the insertion of the cable 12 on the front edge of an insulating body 11, and in the crimping groove 13 A plurality of terminals 14 are arranged corresponding to the core wires of the cable 12 , and a flip cover 15 that can be lifted or closed relative to the insulating body 11 is provided at the crimping groove 13 of the insulating body 11 .

The above flip cover 15 is provided with a round shaft 16 on the same axis on both sides of the cover body and at positions corresponding to the core wires of the cable 12, wherein the round shaft 16 corresponding to the core wires of the cable 12 can be Pressed by the extension arm 17 of the terminal 14 to prevent it from falling off, the integral flip cover 15 can swing around the circular axis 16 to change the state of relative lifting or covering, and in the state of covering with the insulating body 11, The flip cover 15 forms a pressing effect on the cable 12 to prevent the cable from getting loose.

The conventional cable connector shown in Fig. 1 mainly utilizes the way that the flip cover 15 is provided with circular shafts corresponding to the positions of the core wires of the cable 12. When the cover is relatively closed to the insulating body, because the middle section does not have any supporting function, it is easy to bend and deform, resulting in the problem of poor contact between the cable and the terminal.

However, each of the circular shafts 16 of the conventional cable connector shown in FIG. 1 above is a pivot structure with a circular cross-section, and it is a "point" contact with the extension arm 17 of the terminal 14 rather than a "surface" contact. When in use, the flip-up cover 5 is easily lifted off due to a slight external force when it is covered with the insulating body 11, and its practicability and reliability are not ideal as expected.
