Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and specifically to an electrical connector. Background Technology

[0002] In modern electronic devices, electrical connectors, as key components for achieving electrical connections, are widely used in various electronic products, communication equipment, and industrial control systems. Their reliability directly affects the normal operation of the entire electronic system. Common electrical connectors typically include a female base and a male plug. The female base has a socket that mates with the male plug, containing several pins. The male plug has terminals in its terminal holes that mate with the pins. Electrical connection is achieved through the insertion and connection of the pins and terminals.

[0003] However, in actual use, due to insufficient stability in the connection between the terminals and terminal holes, when the male plug is inserted into the female base, the terminal is easily pushed out of the terminal hole by the force of the pin. This phenomenon not only leads to poor contact of the electrical connector, causing unstable signal transmission and circuit breaks, but in severe cases, it can even cause the entire electronic device to malfunction, affecting the normal use and working efficiency of the equipment.

[0004] Currently, to address the issue of terminals being easily pushed out, some technologies increase the friction between the terminal and the terminal hole, or employ special structural designs for the terminal hole. However, these methods, in practical applications, still struggle to effectively guarantee the stability of the terminal during insertion, failing to fundamentally solve the problem of terminals being pushed out of the terminal hole. Therefore, a new technical solution is urgently needed to improve the connection stability of electrical connector terminals and prevent them from being pushed out when inserted with pins, in order to meet the ever-increasing reliability requirements of modern electronic equipment. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present invention provides an electrical connector.

[0006] The technical solution adopted by this utility model is: an electrical connector, including a female end base and a male end plug. The female end base is provided with a socket that mates with the male end plug. The socket is provided with a plurality of pins. The male end plug is provided with a terminal hole that mates with the pins. It also includes a snap-fit ​​plate. The two ends of the snap-fit ​​plate are connected to the male end plug through a connecting structure. One side of the snap-fit ​​plate is provided with a pressing part that presses against the terminal and presses the terminal into the terminal hole.

[0007] Furthermore, a flexible hook is provided on one side of the male plug, and a hook step is provided on the side wall of the female base to connect with the flexible hook.

[0008] Furthermore, the male plug has terminal holes formed by longitudinal and transverse partitions, and the clamping part is provided with a cross-shaped pressure groove that is adapted to the longitudinal and transverse partitions.

[0009] Furthermore, the connection structure includes elastic retaining rings on both ends of the integrally formed fastening pressure plate and fastening steps on both sides of the male plug that engage with the elastic retaining rings.

[0010] Furthermore: the fastening plate is a strip structure, the fastening plate is set on one side of the terminal hole, and the area of ​​the fastening plate covering the terminal hole inlet is less than 1 / 4 of the terminal hole inlet area.

[0011] Furthermore, guide strips are provided on the side walls at both ends of the male plug, and guide grooves are provided on both ends of the female base to guide the guide strips.

[0012] The beneficial effects of this utility model are:

[0013] First, the snap-fit ​​plate effectively improves the connection stability of the terminals. During the insertion of the male plug and the female base, the terminal is no longer easily pushed out of the terminal hole by the pushing force of the pin, ensuring a stable electrical connection between the terminal and the pin. This greatly reduces the probability of problems such as unstable signal transmission and circuit breakage caused by poor contact, effectively ensuring the normal operation of the electronic system.

[0014] Secondly, this structural design optimizes the overall performance of the electrical connector. By firmly securing the terminals within the terminal holes, the risk of failure caused by loose terminals is reduced, extending the connector's lifespan and lowering equipment maintenance costs. Simultaneously, the stable connection performance ensures the connector maintains reliable operation even in various complex environments, meeting the high-reliability connector requirements of modern electronic equipment.

[0015] In addition to the objectives, features and advantages described above, this utility model has other objectives, features and advantages.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0023] This utility model provides an electrical connector.

[0024] In this embodiment, refer to Figure 1-3 The electrical connector includes a female base 1 and a male plug 2. The female base 1 is provided with a socket 3 that mates with the male plug. The socket 3 is provided with a plurality of pins 4. The male plug is provided with a terminal hole 5 that mates with the pins. The connector also includes a locking plate 7. The two ends of the locking plate 7 are connected to the male plug through a connecting structure. One side of the locking plate 7 is provided with a pressing part 8 that presses against the terminal and presses the terminal into the terminal hole.

[0025] In the above technical solution, a locking plate is added to the traditional female connector base and male connector plug. The locking plate is connected to the male connector at both ends via a connecting structure. One side of the locking plate presses against the terminal (e.g., the pressing part presses against the support leg 17 of terminal 6). The mechanical pressure of the locking plate firmly fixes the terminal in the terminal hole, constraining the terminal and preventing it from moving due to force when connected to the pin. This fundamentally solves the problem of terminals being easily pushed out of the terminal hole by the pin, significantly improving the stability and reliability of the terminal connection, ensuring the effectiveness of the electrical connection of the connector, reducing electronic system failures caused by poor contact, and ensuring the stable operation of electronic equipment.

[0026] Specifically, an elastic hook 9 is provided on one side of the male plug, and a hook step 10 connected to the elastic hook is provided on the side wall of the female base.

[0027] In this embodiment, a flexible hook is provided on one side of the male plug, and a matching hook step is provided on the side wall of the female base. When the male plug is inserted into the female base, the flexible hook uses its own elastic deformation to engage with the hook step, achieving a quick and stable connection through mechanical engagement. This makes the connection between the male plug and the female base tighter and more secure. Moreover, the combination of the flexible hook and the hook step makes operation simple, facilitating quick insertion and removal, installation, and maintenance of the electrical connector.

[0028] Specifically, the male plug has a terminal hole 11 formed by longitudinal and transverse partitions, and the pressing part is provided with a cross groove 12 that is adapted to the longitudinal and transverse partitions.

[0029] In this embodiment, terminal holes are formed within the male plug via longitudinal and transverse partitions, providing installation space and positioning structure for the terminals. Simultaneously, a cross-shaped groove adapted to the longitudinal and transverse partitions is provided on the clamping portion of the snap-fit ​​plate. When the snap-fit ​​plate is installed, the cross-shaped groove precisely engages with the longitudinal and transverse partitions, providing positioning. The clamping portion extends into the terminal hole, stably applying pressure to the terminal, ensuring the terminal is securely fixed within the terminal hole, further enhancing the electrical connection performance of the connector.

[0030] Specifically, the connection structure includes elastic retaining rings 13 on both ends of the integrally formed fastening pressure plate and fastening steps 14 on both sides of the male plug that engage with the elastic retaining rings 13.

[0031] In this embodiment, the connection structure employs integrally molded elastic retaining rings at both ends of the snap-fit ​​plate and snap-fit ​​steps on both sides of the male plug. During installation, the elastic retaining rings deform due to their own elasticity, engaging with the snap-fit ​​steps to achieve a quick snap-fit ​​connection between the snap-fit ​​plate and the male plug. This connection method is simple in structure, requiring no additional connectors; installation is completed solely through the mechanical cooperation of the elastic retaining rings and snap-fit ​​steps. This simplifies the connection process between the snap-fit ​​plate and the male plug, making installation convenient and quick, reducing the difficulty and time cost of production assembly, and improving production efficiency. Simultaneously, the tight engagement of the elastic retaining rings and snap-fit ​​steps ensures the secure installation of the snap-fit ​​plate, enabling it to stably apply clamping force to the terminals and ensuring the stable performance of the electrical connector.

[0032] Specifically, the fastening plate is a strip-shaped structure, and the fastening plate is set on one side of the terminal hole, and the area of ​​the fastening plate covering the terminal hole inlet is less than 1 / 4 of the terminal hole inlet area.

[0033] In this embodiment, the snap-fit ​​pressure plate is designed as a strip structure and is located on one side of the terminal hole. The area of ​​the plate covering the terminal hole inlet is less than 1 / 4 of the terminal hole inlet area. This design ensures that the snap-fit ​​pressure plate can apply effective clamping force to the terminal while minimizing obstruction of the terminal hole inlet, thus not affecting the normal insertion of the terminal and the docking operation with the pin, achieving a balance between compact structure and functional implementation.

[0034] Specifically, guide strips 15 are provided on the side walls at both ends of the male plug, and guide grooves 16 are provided on both ends of the female base to guide the guide strips 15.

[0035] In this embodiment, guide strips are provided on the side walls of both ends of the male plug, and corresponding guide grooves are provided on both ends of the female base. When the male plug is inserted into the female base, the guide strips can slide along the guide grooves, providing guidance for the insertion process. This guiding structure ensures that the male plug can be accurately and smoothly inserted into the socket of the female base, allowing the pins to precisely align with the terminals.

[0036] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
