Description

Technical Field

[0001] The present application relates to the field of connectors, and in particular to a female connector. Background Art

[0002] In the field of electronic connection technology, connectors are key components for signal and power transmission between electronic devices, and their structural stability and reliability are crucial. Traditional connector socket designs often rely on the barb structure of the terminal to achieve fixation with the plastic body. Although this spring-type barb design provides assembly convenience to a certain extent, it also has obvious limitations. Specifically, due to the material and structural design of the spring-type barb, it is prone to fatigue deformation after long-term use or when subjected to external stress, resulting in a weakened rebound effect, which in turn makes the terminal less firmly fixed in the connector body.

[0003] Furthermore, when the terminals are assembled into the plastic body, particularly at the wire connection end, which undergoes a 90-degree folding process, the complex and concentrated forces at this location can easily lead to unstable positioning of the terminals within the connector, increasing the risk of pin-out (i.e., the terminals coming out of the connector). This pin-out phenomenon not only affects the electrical performance of the connector but can also cause serious problems such as short circuits and open circuits due to poor contact, posing a threat to the stability and safety of the entire electronic device. Utility Model Content

[0004] The purpose of this application is to provide a connector socket structure, which aims to significantly enhance the fixing effect of the terminal and improve the overall performance of the connector by adding a locking piece.

[0005] In order to achieve the above objectives, this application provides the following technical solutions:

[0006] A connector socket includes a connector body, a terminal and a locking piece. The terminal is installed in the terminal slot of the connector body through hooks on both sides. The locking piece is fastened to the connector body through a snap-on structure. The front end of the locking piece extends forward to have a limiting portion for abutting against the vertical extension portion of the terminal to limit the terminal from moving backward.

[0007] In one embodiment, the snap-on structure includes a first snap-on portion and a second snap-on portion, wherein the first snap-on portion extends outward from the side of the connecting body, and the second snap-on portion is arranged corresponding to the first snap-on portion, and the second snap-on portion protrudes inward from the extension portion of the locking plate.

[0008] In one embodiment, the front side surface of the first buckle portion is a first inclined limiting surface, and the rear side surface of the first buckle portion is a first inclined guiding surface.

[0009] In one embodiment, the front side surface of the second buckle portion is a second inclined guide surface, the rear side surface of the second buckle portion is a second inclined limiting surface, and the second buckle portion is buckled on the first inclined surface through the second inclined surface.

[0010] In one embodiment, a limiting guide groove is provided on the bottom surface of the locking piece.

[0011] In one embodiment, a protrusion is provided on the upper surface of the locking piece to facilitate pushing the locking piece into the connector body for installation.

[0012] The beneficial effects of this application are:

[0013] (1) The present application provides a special terminal slot on the connector body and utilizes the barbed structure on both sides of the terminal to achieve initial fixation. This design ensures the stability and accuracy of the terminal during initial installation. Furthermore, the introduction of the locking piece and its close connection with the connector body through the snap-fit structure not only simplifies the assembly process, but also forms a strong blocking mechanism through the limit portion at the front end of the locking piece directly abutting against the vertical extension of the terminal, effectively preventing the terminal from retreating or loosening, thereby significantly enhancing the fixing strength of the terminal.

[0014] (2) This application addresses the common problem of PIN withdrawal at the 90-degree bend line in traditional connectors. By optimizing the overall structural layout, the setting of the locking piece not only enhances the overall fixing effect of the terminal, but also the limiting effect of the locking piece further restricts the movement of the terminal in this area, thereby effectively reducing the risk of PIN withdrawal and improving the reliability and durability of the connector.

[0015] (3) Although the present application adds a locking plate assembly, the present design uses a snap-fit structure to achieve quick engagement of the locking plate with the connector body, which not only ensures the convenience of assembly but also facilitates subsequent maintenance and replacement. When the terminal needs to be replaced or repaired, the locking plate and terminal can be easily removed by simply releasing the snap-fit structure, which greatly improves work efficiency.

[0030] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1 As shown, this embodiment provides a connector receptacle, which primarily includes a connector body 1, four terminals 2, and two locking plates 3. The connector body 1 is internally provided with four terminal slots 4. These slots 4 are divided into two groups, one above the other, with two terminals in each group, symmetrically arranged to accommodate the four terminals 2. Each terminal 2 is securely mounted in its corresponding slot 4 via barbs 21 on either side, ensuring that the terminal 2 is positioned and secured within the connector body 1.

[0033] like Figure 2 As shown, the two locking pieces 3 are respectively installed corresponding to the upper and lower groups of terminals 2, and are fastened to the upper and lower sides of the connector body 1 through the snap-fit structure 31. Figure 6 and Figure 7As shown, a limiting portion 32 extends forward from the front end of each locking piece 3, and each limiting portion 32 corresponds to a vertical extension portion 22 of a terminal 2, limiting the backward movement of the terminal 2 in the direction of insertion of the male end of the connector through physical contact, thereby enhancing the stability and reliability of the connection.

[0034] Example 2

[0035] like Figure 2 、 Figure 3 and Figure 4 As shown, in this embodiment, the specific implementation of the snap-fit structure 31 is further refined. The snap-fit structure 31 comprises a first snap-fit portion 311 and a second snap-fit portion 312. The first snap-fit portion 311 extends outward from the side of the connector body 1. Its front side is designed as a first inclined limiting surface 3111, which provides a stable limiting effect after the locking plate 3 is installed. The rear side is designed as a first inclined guide surface 3112, which facilitates the smooth sliding of the locking plate 3 during installation.

[0036] Correspondingly, the second latch portion 312 is formed by protruding inward from the extension portion 33 of the locking plate, and its front side surface is a second inclined guide surface 3121, which matches the first inclined guide surface 3112 of the first latch portion 311, guiding the locking plate 3 to slide in smoothly; the rear side surface is a second inclined limiting surface 3122. When the locking plate 3 is installed in place, the second inclined limiting surface 3122 is engaged with the first inclined limiting surface 3111, thereby achieving firm locking of the locking plate 3.

[0037] Example 3

[0038] like Figure 3 As shown, to further optimize the installation and use experience of the locking plate 3, this embodiment adds additional design elements to the locking plate 3. First, a limiting guide groove 34 is provided on the bottom surface of the locking plate 3. This groove design helps guide the locking plate 3 to correct alignment and smooth sliding into the connector body 1 during installation, improving installation convenience and accuracy.

[0039] like Figure 3 As shown, in addition, a protrusion 35 is provided on the upper surface of the locking piece 3. This design is convenient for the user to push the locking piece 3 for installation by fingers or tools.
