Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and specifically to a female end of a connector. Background Art

[0002] In electronic devices, connectors play a crucial role. They are responsible for achieving electrical connections between different circuits or components. Traditional connectors usually consist of a male end and a female end, where the female end contains multiple terminal holes for receiving the corresponding terminals on the male end to form electrical contacts.

[0003] However, in the existing designs of the female end of connectors, the fixing stability of the terminals in the terminal holes is often insufficient. Especially under the influence of environmental factors such as long-term use, vibration, and temperature changes, the terminals may become loose, resulting in the terminals detaching or poor contact, thereby affecting the quality of signal transmission and the reliability of the system. In addition, due to the lack of an effective fixing mechanism, the terminals are also prone to position deviation during the assembly process. Utility Model Content

[0004] In view of the deficiencies in the background art, the present utility model provides a female end of a connector.

[0005] The technical solution adopted by the present utility model is: a female end of a connector, including a female end housing and terminals, and further including a locking piece. A plurality of terminal holes are provided at equal intervals along the width direction of the female end housing. A locking piece groove for inserting the locking piece is provided on one side of the terminal hole. One end of the locking piece extends with a pressing plate that extends above the terminal hole. A limiting step for limiting the terminal is provided in the terminal hole at the top of the pressing plate. After the pressing plate is inserted into the terminal hole, the convex step of the terminal can be pressed and limited between the limiting step and the pressing plate by the top of the pressing plate. The number and position of the pressing plates correspond one-to-one with the number and position of the terminal holes, and a connecting structure for connecting with the female end housing is provided on the pressing plate located on the outermost side of the locking piece.

[0006] Further, the connecting structure includes a hook portion on the outside of the pressing plate and grooves on both sides of the female end housing.

[0007] Further, the groove extends to the end away from the locking piece.

[0008] Further, a limiting platform plate is provided at one end of the locking piece away from the pressing plate.

[0009] Further, a spring step is provided on the locking piece below the limiting platform plate, a spring groove adapted to the spring step is provided on the female end housing, and a pre-tightening spring is connected between the spring step and the spring groove.

[0010] Further, the upper and lower sides of the top of the pressing plate have guiding inclined surfaces.

[0011] Furthermore, a connecting rocker is integrally formed on the female end housing.

[0012] The beneficial effects of the present utility model are as follows: By providing a lock piece, the terminal is limited and fixed by the pressing plate on the lock piece and the limiting step in the terminal hole, so that the terminal can be fixed more firmly in the terminal hole, greatly reducing the risk of poor contact caused by terminal loosening, ensuring the reliability and signal transmission quality of the connector in various working environments, and enhancing the overall performance of the product.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, then such directional indications are only used to explain the relative positional relationship, movement conditions, etc. between components in a certain specific posture (as shown in the attached drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0022] The present utility model provides a female end of a connector.

[0023] In this embodiment, referring to Figures 1-5 , the female end of the connector includes a female end housing 1 and terminals 2, and further includes a locking piece 3. A plurality of terminal holes 4 are provided at equal intervals along the width direction of the female end housing. A locking piece groove 5 for inserting the locking piece is provided on one side of the terminal hole. One end of the locking piece extends with a pressing plate 6 extending above the terminal hole. A limiting step 7 for limiting the terminal is provided in the terminal hole at the top of the pressing plate. After the pressing plate is inserted into the terminal hole, the convex step 8 of the terminal 2 can be pressed and limited between the limiting step and the pressing plate by the top of the pressing plate. The number and position of the pressing plates correspond one by one to the number and position of the terminal holes, and a connecting structure for connecting with the female end housing is provided on the pressing plate at the outermost side of the locking piece.

[0024] In this application, by providing a locking piece and using the pressing plate on the locking piece and the limiting step in the terminal hole to limit and fix the terminal, the terminal can be fixed more firmly in the terminal hole, greatly reducing the risk of poor contact caused by terminal loosening, ensuring the reliability and signal transmission quality of the connector in various working environments, and enhancing the overall performance of the product.

[0025] Specifically, the connecting structure includes a hook portion 9 outside the pressing plate and grooves 10 on both sides of the female end housing.

[0026] In this embodiment, through the cooperation of the hook portion and the grooves, the quick connection and disconnection of the locking piece and the female end housing are realized, simplifying the assembly process and also facilitating the maintenance and replacement of components.

[0027] Specifically, the groove extends to the end away from the locking piece.

[0028] In this embodiment, the groove extending to the end away from the locking piece facilitates the processing of the groove and reduces the processing cost.

[0029] Specifically, a limiting platform plate 11 is provided at the end of the locking piece away from the pressing plate.

[0030] In this embodiment, the limiting platform plate plays a role in limiting the locking piece, preventing the locking piece from penetrating too deeply into the terminal hole, ensuring the correct position of the locking piece, and avoiding damage to the internal structure.

[0031] Specifically, a spring step 12 is provided on the locking piece below the limit platen, a spring groove 13 adapted to the spring step is provided on the female terminal housing, and a pre-tightening spring 14 is connected between the spring step and the spring groove.

[0032] In this embodiment, the existence of the pre-tightening spring provides an additional elastic force, ensuring the continuous pressure of the pressing plate on the terminal, and maintaining a stable contact pressure even under long-term use or temperature changes, thus improving the reliability of the connection.

[0033] Specifically, guiding inclined surfaces 15 are provided on both the upper and lower sides of the top of the pressing plate.

[0034] In this embodiment, the design of the guiding inclined surfaces makes it easier for the pressing plate to enter the terminal hole, reducing the resistance during assembly.

[0035] Specifically, a connecting rocker 16 is integrally formed on the female terminal housing.

[0036] In this embodiment, the connecting rocker is used for mating connection with the male end. The integrally formed connecting rocker ensures the overall mechanical strength of the female terminal housing.

[0037] All technicians should note that although the present utility model has been described according to the above specific embodiments, the idea of the present utility model is not limited to this utility model alone. Any modification using the idea of the present utility model will be included in the scope of protection of this patent right.
