加强连接器Reinforced connector

技术领域technical field

本发明涉及一种用于电流或信号转接的连接器，尤其涉及一种接触件与绝缘体之间的配合可靠的加强连接器。The invention relates to a connector for current or signal transfer, in particular to a reinforced connector with reliable cooperation between a contact piece and an insulator.

背景技术Background technique

现有一种连接器如图1、2所示，包括壳体1，壳体1内设置有贯穿前后的通孔，壳体的通孔内通过绝缘部件固定设置上有接触件2，绝缘部件包括固定设置在壳体1内的前绝缘体4与后绝缘体，后绝缘体的后方还设置有尾部绝缘体。接触件2穿设在前绝缘体、后绝缘体与尾部绝缘体的内孔中。前绝缘体4的前端部设置在内翻的固定翻沿5。接触件2通过定位爪3实现在绝缘部件内的定位，定位爪3包括一个筒状体，筒状体的内壁上设置有一端固定在筒状体的内壁上，另一端自由倾斜伸向筒状体的轴线的定位弹片，定位爪3通过其筒状体套设在接触件2上，定位爪处于前绝缘体的内孔中。定位爪的前端面顶压在前绝缘体4的固定翻沿5的外缘部位，定位爪的后端面顶压在后绝缘体的前端面上。接触件2上设置有定位轴环6，定位轴环6的前端面顶压在前绝缘体4的固定翻沿5的内缘部位，定位轴环6的后端面与定位爪的定位弹片顶压配合，从而实现接触件在壳体1内的固定。在装配时，是先将前绝缘体装配在壳体1的内孔中，然后将定位爪插设在前绝缘体4的内孔中，再依次装上后绝缘体与尾部绝缘体，最后从后端将接触件2穿入各个绝缘体的内孔中，当定位轴环碰触到定位爪的定位弹片时，会挤压定位弹片，使定位弹片弹性变形，当定位轴环越过定位弹片后，定位弹片恢复原状并与定位轴环的后端面顶压。由于接触件需要克服定位弹片的弹力，因此在装配时需要在接触件上施加一定的推压力，在操作时，如果推压力的大小控制不好，接触件的定位轴环就会撞到前绝缘体的固定翻沿，由于结构限制，固定翻沿的轴向尺寸较小，一般只有0.76-1.1mm，这就使得固定翻沿很容易被接触件撞破，造成前绝缘体损坏。As shown in Figures 1 and 2, there is an existing connector, which includes a housing 1, and a through hole passing through the front and back is arranged in the housing 1, and acontact piece 2 is fixed in the through hole of the housing through an insulating part, and the insulating part includes The front insulator 4 and the rear insulator are fixedly arranged in the casing 1, and a tail insulator is also arranged behind the rear insulator. Thecontact piece 2 passes through the inner holes of the front insulator, the rear insulator and the tail insulator. The front end of the front insulator 4 is provided with an inwardly turned fixed edge 5 . Thecontact piece 2 is positioned in the insulating part through thepositioning claw 3. Thepositioning claw 3 includes a cylindrical body, and the inner wall of the cylindrical body is provided with one end fixed on the inner wall of the cylindrical body, and the other end is freely inclined to the cylindrical body. The positioning shrapnel of the axis of the body, thepositioning claw 3 is sleeved on thecontact piece 2 through its cylindrical body, and the positioning claw is located in the inner hole of the front insulator. The front end face of locating pawl presses on the fixed turning edge 5 of front insulator 4, and the rear end face of locating pawl presses on the front end face of rear insulator. Thecontact piece 2 is provided with apositioning collar 6, the front end of thepositioning collar 6 presses against the inner edge of the fixed edge 5 of the front insulator 4, and the rear end of the positioning collar 6 presses against the positioning shrapnel of the positioning claw. , so as to realize the fixation of the contact piece in the housing 1 . When assembling, the front insulator is first assembled in the inner hole of the housing 1, and then the positioning claws are inserted in the inner hole of the front insulator 4, and then the rear insulator and the tail insulator are installed in sequence, and finally the contact is made from the rear end.Part 2 penetrates into the inner holes of each insulator. When the positioning collar touches the positioning shrapnel of the positioning claw, it will squeeze the positioning shrapnel and elastically deform the positioning shrapnel. When the positioning collar passes over the positioning shrapnel, the positioning shrapnel returns to its original shape And press against the rear end face of the positioning collar. Since the contact piece needs to overcome the elastic force of the positioning shrapnel, it is necessary to exert a certain pushing force on the contact piece during assembly. During operation, if the pushing force is not well controlled, the positioning collar of the contact piece will hit the front insulator Due to structural limitations, the axial dimension of the fixed edge is relatively small, generally only 0.76-1.1mm, which makes the fixed edge easily broken by the contact, resulting in damage to the front insulator.
