Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and specifically to a connector facilitating the insertion, installation and positioning of terminals. Background Art

[0002] In modern electronic devices and automated systems, connectors are one of the key components for realizing electrical signal and power transmission. A connector usually consists of a male end and a female end. A series of terminal holes are provided on the female end housing to accommodate and fix terminals, thereby achieving electrical connection with external wires or circuit boards. In traditional connector designs, the installation of terminals often lacks a good positioning and fixing structure, resulting in poor stability of the installed terminals. Under frequent plugging and unplugging operations, the fixation between the terminals and the terminal holes may become loose, leading to poor contact. Utility Model Content

[0003] Aiming at the deficiencies in the background art, the present utility model provides a connector facilitating the insertion, installation and positioning of terminals.

[0004] The technical solution adopted by the present utility model is as follows: A connector facilitating the insertion, installation and positioning of terminals includes a female end housing. A number of terminal holes for installing terminals are spacedly provided on the female end housing. The terminal includes a wiring end and a plugging end. An elastic abutting piece formed by bending upward is provided at the end of the transition frame in the middle of the terminal. An elastic retaining strip is provided in the middle of the transition frame. The height of the elastic retaining strip is lower than the maximum height of the elastic abutting piece. A front retaining step abutting against the elastic abutting piece and a rear retaining step abutting against the elastic retaining strip are provided in the terminal hole. An introducing inclined surface is provided on one side of the front retaining step located at the terminal opening.

[0005] Further, the upward inclination angle of the elastic abutting piece is 25 - 45 degrees.

[0006] Further, a reinforcing plate is provided on the rear retaining step, and a buffer rubber pad is adhered to the side surface of the rear retaining step.

[0007] Further, a number of docking guiding grooves are spacedly provided on the upper and lower side surfaces of the female end housing. An adapting convex strip is provided on the docking guiding groove on the upper side.

[0008] Further, a guiding retaining strip is provided on the side surface of the elastic retaining strip, and the side surface of the guiding retaining strip abuts against the side surface of the front retaining step.

[0009] Further, it further includes a male end socket. The male end socket includes a socket bottom plate and plug posts provided on the socket bottom plate. The plug posts are in plugging fit with the above-mentioned terminal holes, and insertion terminals are provided in the plug posts.

[0010] Further, both ends of the socket base plate are provided with connecting sleeves. Both sides of the connecting sleeve have conical fan-shaped pieces. A fitting gap is left between the conical fan-shaped piece and the outer wall of the connecting sleeve. A fitting opening is provided on the socket base plate below the conical fan-shaped piece.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. Simplify the installation process: During installation, the elastic abutting piece is aligned with the pouring inclined surface and pressed in. At the same time, the cooperation between the elastic abutting piece and the elastic retaining strip with the front retaining step and the rear retaining step can automatically complete the positioning and fixing of the terminal, without the need for additional tools or complex manual adjustment, greatly simplifying the terminal installation process and improving production efficiency.

[0013] 2. Enhance connection stability: The elastic abutting piece has elasticity and can firmly press the terminal. At the same time, a tolerance margin is left for the installation of the terminal. The design of the elastic structure ensures the close contact between the terminal and the terminal hole. Even in an environment of vibration or temperature change, good electrical connection can be maintained, avoiding problems of poor contact.

[0014] 3. Improve assembly accuracy: The guiding inclined surface on the front retaining step helps to guide the terminal to correctly align with the terminal hole, reducing the error rate during the assembly process and ensuring that each terminal can be accurately installed in place. At the same time, the guiding inclined surface on the front retaining step can play a good guiding role.

[0015] 4. Suitable for high-density connectors: For high-density connector applications, the structure of the present application is particularly effective. It can achieve fast and reliable terminal installation in a narrow space, meeting the requirements of miniaturization and high performance of modern electronic devices.

[0016] In addition to the purposes, features, and advantages described above, the present utility model has other purposes, features, and advantages. The following will refer to the accompanying drawings to further elaborate on the present utility model in detail. Description of the Drawings

[0035] Specifically, a guiding retaining bar 16 is provided on the side surface of the elastic retaining bar, and the side surface of the guiding retaining bar abuts against the side surface of the front retaining step.

[0036] In this embodiment, the cooperation between the guiding retaining bar and the side surface of the front retaining step further improves the guiding accuracy when the terminal is inserted, ensuring that the terminal is fixed in the correct position.

[0037] Specifically, it further includes a male end socket 17, the male end socket includes a socket bottom plate 18 and insertion posts 19 provided on the socket bottom plate, the insertion posts are inserted and matched with the above-mentioned terminal holes, and an insertion terminal 20 is provided in the insertion posts.
