Description

Technical Field

[0001] The utility model relates to the technical field of connector design, in particular to a square clamping plate type female terminal and a female connector. Background Art

[0002] Female header terminals, as key components in electronic connectivity, play a vital role in connecting components on circuit boards. They are typically made of high-quality metal materials, offering excellent conductivity and mechanical strength. Female header terminals often feature multiple pins arranged at a fixed pitch for precise docking with corresponding pin headers or other connectors. Their unique square-shaped sandwich plate structure not only enhances connection stability but also optimizes smooth insertion and removal. During insertion and removal, the female header terminal's spring clip design ensures good contact with the pin header or other connector, achieving a stable and reliable electrical connection. This structure also effectively resists external shock and vibration, reducing loose connections or failures caused by environmental factors.

[0003] In the prior art, the spring clips on the female terminals are usually set in T-shape or I-shape to facilitate the insertion and fixation of the spring clips. However, during the application of such spring clips, the stress is not easily dispersed due to the consistency of the upper and lower dimensions, which can easily lead to insertion difficulties.

In one embodiment, the fixing strip 1, the connecting column 2 and the terminal body 3 are formed by stamping, wherein the fixing plate 11 extends along the length direction, the connecting column 2 is used to connect the fixing plate 11 and the terminal body 3, and the terminal body 3 is located below the connecting column 2.

[0021] In one embodiment, see Figure 1 The fixing strip 1 is long and can be fixed by winding during use. In one embodiment, the fixing strip 1 is composed of a plurality of fixing plates 11, each of which is used to connect to a terminal body 3. Adjacent fixing plates 11 are connected by tear lines 12, thereby ensuring a stable connection between adjacent fixing plates 11. In one embodiment, in order to reduce counterweight and save materials, a plurality of hollow holes 13 are provided on the fixing plates 11.

[0022] In one embodiment, the connecting post 2 is integrally formed with the fixing bar 1. Two connecting posts 2 are provided for each terminal body 3. The connecting posts 2 are arranged in a right triangle shape, and the two connecting posts 2 are symmetrically arranged along the center line of the terminal. In one embodiment, the short right-angled side of the connecting post 2 is connected to the fixing bar 1. The three corners of the connecting post 2 are all rounded to facilitate processing. One of the acute angles of the connecting post 2 is connected to the terminal body 3, and the acute angle pointing to the terminal body 3 is between 10-15 degrees. Preferably, the acute angle of the connecting post 2 pointing to the terminal body 3 is 10.6 degrees.

[0023] See also Figure 1 and Figure 2The terminal body 3 includes a bottom plate 31, and the bottom plate 31 is fixed to one end of the fixing strip 1 and the two connecting columns 2. In one embodiment, the bottom plate 31 and the connecting column 2 are integrally formed, and side strips 32 are provided on both sides of the width direction of the bottom plate 31. The side strips 32 extend along the length direction of the bottom plate 31 and point to one end of the fixing strip 1. The side strips 32 are bent away from one end of the fixing strip 1; a buckle 321 is provided on the side opposite to the side of the side strip 32, and the buckle 321 is tilted, and the tilt direction of the buckle 321 points downward and outward. The buckle 321 on the side strip 32 is convenient for connecting and fixing the terminal body 3.

[0024] See also Figure 1 and Figure 2 An insertion opening 33 is provided at one end of the bottom plate 31 away from the fixing bar 1 . The insertion opening 33 is square. In one embodiment, the insertion opening 33 is formed by bending a metal strip at the end surface of the bottom plate 31 .

[0025] In order to facilitate the insertion and fixation of the terminal body 3, in one embodiment, a spring piece 331 is provided on the side of the insertion port 33 away from the base plate 31, and the width of the spring piece 331 gradually decreases from one end of the base plate 31 away from the fixing strip 1 to the other end, and, in one embodiment, the spring piece 331 is concavely arranged at one end pointing to the fixing strip 1.

[0026] See also Figure 3 The present application also provides a square clamp-type female connector, which includes the terminal body 3 and the female rubber core 4 mentioned above. A cavity 41 is provided in the female rubber core 4, and the terminal body 3 on the female terminal is inserted into the cavity 41.

[0027] The square, clamped-plate female connector provided in this application significantly improves the performance and stability of electronic connectors with its unique structural features. This design cleverly incorporates a recessed spring clip 331. This innovation not only optimizes the insertion process when the pin header and female connector are connected, but also greatly enhances the reliability of the connection. During insertion and removal, the recessed spring clip 331 effectively guides the pin header into position, reducing wear and jamming caused by misalignment or improper force, thereby extending its service life.

[0028] In addition, this design significantly enhances the deformation resistance of the spring clip 331. When the traditional female terminal is frequently plugged and unplugged or subjected to large external forces, the spring clip 331 is prone to deformation, affecting the stability of the connection and the quality of signal transmission. The square clamping plate structure of the present application effectively disperses the external impact by reasonably distributing the stress, so that the spring clip 331 is more durable and less prone to permanent deformation while maintaining sufficient elasticity. The structural stability also brings about a significant improvement in the conductive performance. The tight square clamping design ensures a stable and low-resistance electrical connection between the pin header and the female terminal, reduces the risk of poor contact and signal attenuation, and improves the efficiency and accuracy of data transmission. At the same time, this design also has good anti-electromagnetic interference ability, ensures the purity of signal transmission, and meets the needs of modern electronic equipment for high reliability and high-performance connectors.
