Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a front-opening electrical connector. Background Technology

[0002] In existing electrical connectors, the reliability of the electrical connection between the terminals and the mating parts is a core performance characteristic. In traditional structures, the contact between the terminals and the mating parts relies heavily on the elasticity of the terminals themselves to achieve a proper fit. However, under long-term use or vibration environments, the terminals are prone to decreased deformation capacity due to elastic fatigue, or positional misalignment due to insertion and removal operations, leading to problems such as poor contact, unstable signal transmission, or even open circuits. Especially in scenarios requiring frequent insertion and removal or operating under vibration, this connection method relying on the elasticity of the terminals cannot guarantee continuous and stable contact pressure, which may affect the operational reliability of the electrical connector. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a front-opening electrical connector.

[0004] The objective of this utility model can be achieved through the following technical solution: A front-opening electrical connector includes a rubber base, a slot is provided at the front end of the rubber base, and multiple terminals are spaced apart inside the rubber base, with one end of each terminal extending into the slot; a receiving groove corresponding to each terminal is provided through the upper part of the slot; a pressure cover is rotatably connected to the rubber base above the slot, and multiple pressure blocks corresponding to the receiving grooves are arranged spaced apart on the side of the pressure cover facing the rubber base, and the pressure blocks can pass through the receiving grooves and abut against the terminals; a locking assembly is provided on the rubber base to cooperate with the pressure cover to achieve locking.

[0005] Preferably, the locking assembly includes an elastic buckle, the rubber base has an installation groove for installing the elastic buckle, and the pressure cover has a groove corresponding to the elastic buckle.

[0006] Preferably, the elastic buckle has an L-shaped structure, with a mounting part connected to the mounting groove and an elastic part extending toward the pressure cover. One side of the elastic part is connected to a lug, and the end of the elastic part is provided with a buckle on the side near the rubber seat.

[0007] Preferably, the terminal includes an upper clamping arm and a lower clamping arm, one end of the upper clamping arm and the lower clamping arm are provided with a contact point, and the other end is connected as a whole by a connecting arm. A welding foot is provided at the bottom of one side of the connecting arm.

[0008] Preferably, the front end of the cap is provided with a lifting handle.

[0009] The beneficial effects of this utility model are as follows: the pressure block is driven by the pressure cover to pass through the receiving groove corresponding to the terminal. The pressure block can accurately act on the terminal and apply stable pressure, forcing the terminal to deform and fit tightly with the mating part. This overcomes the problem of loose contact that is easily caused by the elasticity of the terminal itself in the traditional structure. At the same time, the locking assembly can reliably lock after the pressure cover is closed, ensuring that the pressure of the pressure block on the terminal is continuously stable, thereby ensuring that the terminal and the mating part always maintain a tight conductive contact and greatly reducing the risk of poor contact.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] See Figures 1 to 5 As shown, the structure of this utility model is as follows: a front-opening electrical connector includes a rubber base 1, a slot 2 is provided at the front end of the rubber base 1, and a plurality of terminals 3 are spaced apart inside the rubber base 1, with one end of each terminal 3 extending into the slot 2; a receiving groove 4 corresponding to each terminal 3 is provided through the upper part of the slot 2; a pressure cover 5 is rotatably connected to the rubber base 1 above the slot 2, and a plurality of pressure blocks 6 corresponding to the receiving grooves 4 are arranged spaced apart on the side of the pressure cover 5 facing the rubber base 1, and the pressure blocks 6 can pass through the receiving grooves 4 and abut against the terminals 3; the rubber base 1 is provided with a locking assembly 7 that cooperates with the pressure cover 5 to achieve locking. Specifically, the rubber base 1 serves as the main... The frame provides support and insulation, and the slot 2 at its front end provides insertion space for the mating parts. The terminals 3 are spaced apart in the base 1, with one end extending to the slot 2 for conductive contact with the mating parts to achieve current or signal transmission. The receiving groove 4 passes through the top of the slot 2, providing a movement channel for the pressure block 6 and ensuring accurate alignment. The pressure cover 5 is rotatably connected to the top of the base 1, and the pressure block 6 on the side facing the base 1 can rotate with the pressure cover 5 and pass through the receiving groove 4. When the pressure cover 5 is closed, it presses against the terminal 3, causing the terminal 3 to deform and make tight contact with the mating parts. The locking assembly 7 locks the pressure cover 5 after it is closed to prevent loosening and achieve reliable electrical connection.

[0021] like Figures 3 to 5 As shown, the locking assembly 7 includes an elastic buckle 8. The rubber base 1 has a mounting groove 9 for installing the elastic buckle 8, and the pressure cover 5 has a corresponding slot 10 for the elastic buckle 8. Specifically, the mounting groove 9 is used to fix the elastic buckle 8, providing installation space and limiting displacement. The elastic buckle 8 has elastic deformation capability and can cooperate with the slot 10 on the pressure cover 5. The slot 10 serves as a mating structure, forming a snap-fit ​​with the elastic buckle 8. During the closing process of the pressure cover 5, the elastic buckle 8 is deformed under pressure. When the pressure cover 5 is fully closed, the elastic buckle 8 resets and snaps into the slot 10, thus locking the pressure cover 5. When it is necessary to open the pressure cover 5, an external force is applied to deform the elastic buckle 8 and disengage it from the slot 10, releasing the locking state.

[0022] like Figure 5 As shown, the elastic buckle 8 has an L-shaped structure, with a mounting portion 11 connected to the mounting groove 9 and an elastic portion 12 extending towards the pressure cover 5. A lug 13 is connected to one side of the elastic portion 12, and a buckle 14 is provided at the end of the elastic portion 12 near the rubber seat 1. Specifically, the L... The mounting part 11 of the elastic buckle 8 is connected to the mounting groove 9 to fix the elastic buckle 8 on the rubber base 1; the elastic part 12 extends towards the pressure cover 5 and is elastic, providing deformation capability for snapping; the lug 13 facilitates the user to apply external force to drive the elastic part 12 to deform, making unlocking operation convenient; the buckle 14 is set at the end of the elastic part 12 for direct snapping with the slot 10 of the pressure cover 5, and the upper part of the buckle 14 is an inclined slope. When the pressure cover 5 is closed, the inclined surface of the buckle 14 contacts the slot 10 and causes the elastic part 12 to deform. When the buckle 14 is fully inserted into the slot 10, the elastic part 12 returns to its original position, and the buckle 14 is locked with the slot 10; when unlocking, the lug 13 applies force to the elastic part 12, causing it to deform and drive the buckle 14 to disengage from the slot 10, thereby unlocking the pressure cover 5.

[0023] like Figure 2 As shown, terminal 3 includes an upper clamping arm 15 and a lower clamping arm 16. One end of the upper clamping arm 15 and the lower clamping arm 16 is provided with a contact 17, and the other end is connected to the terminal by a connecting arm 18. The bottom of one side of the connecting arm 18 is provided with a welding foot 19. Specifically, the upper clamping arm 15 is located in the receiving groove 4. On the one hand, it restricts its lateral displacement by the side wall of the receiving groove 4 to play a limiting role. On the other hand, it has elastic deformation capability and can be used as a movable clamping part. The lower clamping arm 16 is fixed to the bottom of the slot 2 as a fixed support and forms an upper and lower corresponding structure with the upper clamping arm 15. The ends of the upper clamping arm 15 and the lower clamping arm 16 are provided with contacts 17 for contacting the conductive part of the mating part. The connecting arm 18 connects the upper clamping arm 15 and the lower clamping arm 16 into one piece and achieves conductive connection with the external circuit through the welding foot 19. When the cover is closed, the pressure block 6 passes through the receiving groove 4 and precisely acts on the upper clamping arm 15, forcing the upper clamping arm 15 to deform downward elastically, and cooperate with the fixed lower clamping arm 16 to clamp the mating parts, so that the contact points 17 of the two are tightly attached to the surface of the mating parts, achieving a stable electrical connection; when the cover is opened, the pressure block 6 disengages from the upper clamping arm 15 along with the cover 5, and the upper clamping arm 15 rebounds upward under its own elasticity, releasing the mating parts and returning to its initial position, making it easy to remove the mating parts.

[0024] like Figure 4 As shown, the front end of the pressure cap 5 is provided with a lifting handle 20. Specifically, the lifting handle 20 is used to provide a point for applying force to the pressure cap 5, so as to facilitate opening or closing the pressure cap 5.

[0025] In practical use, when connecting the mating parts, first insert the mating parts into the slot 2 at the front end of the glue base 1, so that the mating parts are located at the terminal 3 extending into the slot 2; then rotate the pressure cover 5 above the slot 2 on the glue base 1, so that the pressure cover 5 rotates toward the glue base 1, and the pressure block 6 on the pressure cover 5 corresponding to the receiving groove 4 rotates with the pressure cover 5 and passes through the receiving groove 4 above the slot 2 until the pressure block 6 abuts against the terminal 3; continue to rotate the pressure cover 5, and the pressure block 6 applies pressure to the terminal 3, forcing the terminal 3 to deform and make tight contact with the mating parts; when the pressure cover 5 is fully closed, the locking assembly 7 on the glue base 1 cooperates with the pressure cover 5 to lock it, preventing the pressure cover 5 from loosening, and completing the connection of the mating parts.

[0026] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
