Description

Technical Field

[0001] This utility model relates to the technical field of connectors, specifically to a terminal connector snap-fit ​​structure. Background Technology

[0002] Connectors are components frequently encountered by electronic engineers. In China, they are also known as plugs, sockets, or connectors. Generally, they refer to electrical connectors, which are devices that connect two active devices to transmit current or signals.

[0003] An existing type of terminal snap connector generally includes a wire end and a plastic sheath. The wire end is provided with a single snap, which is inserted into the plastic sheath and fixed to the plastic sheath.

[0004] The existing technical solutions mentioned above have the following drawbacks: the holding force provided by a single clip on the terminal connector in the sheath is insufficient, which can easily cause the wire end to detach from the plastic sheath. Utility Model Content

[0005] The purpose of this invention is to provide a terminal connector snap-fit ​​structure that increases its holding force in the sheath.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] It includes a conductor end and a female end. The conductor end includes several conductors. The female end has an electrical connection groove for cooperating with the conductors. The end of the conductor is fixedly connected to a first buckle. The electrical connection groove is fixedly provided with a first locking block that cooperates with the first buckle. An elastic metal sheet extends from the outer wall of the first buckle. The first locking block abuts against the end of the elastic metal sheet. There are several conductors. The number of electrical connection grooves matches the number of conductors.

[0008] By adopting the above technical solution, the first buckle is installed in conjunction with the electrical connection groove and the first locking block. During use, the first buckle is inserted into the electrical connection groove to achieve electrical connection. When the first buckle is in place, the elastic metal piece automatically springs up to abut against the first locking block, thereby locking the wire connection. During installation, simply insert the first buckle directly into the designated position of the electrical connection groove to complete the quick locking connection of the wire. Compared with the connection method of tightening with bolts, the connection of the elastic metal piece buckle has a significantly more convenient installation effect. When installing a large number of wires, the overall installation efficiency is much higher than that of traditional bolt-fixed connectors, effectively improving the utilization efficiency of the equipment. When disassembling, pressing the elastic metal piece to disengage it from the first locking block can unlock and remove the wire.

[0009] Furthermore, a second buckle is fixedly provided on the outer wall of the first buckle near the wire end, and a movable groove aligned with the second buckle is opened through the outer wall of the female end. A second locking block is engaged with the outer wall of the female end and embedded in the movable groove. A locking area is opened on the inner wall of the second buckle at intervals from the movable groove, and the second locking block is embedded in the locking area and abuts against the second buckle.

[0010] By adopting the above technical solution, the second buckle, in conjunction with the movable groove and the second buckle block, can play a double role in securing the wire. In use, first, the first buckle is inserted into the electrical connection groove, at which point the movable groove is aligned with the second buckle. Then, the second buckle block is engaged and installed, embedding itself into the movable groove and further into the engagement area. When the wire is pulled by external force, the second buckle block will abut against the second buckle, preventing the wire from falling off under external force, thus further improving the connection between the wire and the female end. The second buckle can be either an elastic metal sheet or a fixed block. When both the first and second buckles are made of elastic metal sheets, pulling the wire will cause the first buckle to slide slightly adaptively, providing a good buffering effect and preventing the wire from falling off due to excessive pulling force in a short time. When the second buckle is made of a fixed block, the firm abutment prevents the first buckle from falling off due to the elastic metal sheet being pulled, resulting in a more stable connection and greater tensile strength. The buckle type can be selected according to the actual situation.

[0011] Furthermore, the second locking block is disposed in contact with the top wall of the female end, and elastic locking hooks are provided at both ends of the second locking block to fit the side wall of the female end. The outer wall of the female end is provided with locking protrusions that cooperate with the elastic locking hooks.

[0012] By adopting the above technical solution, the elastic locking hook and the locking protrusion have a good locking effect. Pressing the second locking block causes the elastic locking hook to slide against the side wall of the female end until the elastic locking hook hooks onto the locking protrusion. At this time, the second locking block is fully embedded into the locking area through the movable groove. When disassembling, pry the elastic locking hook to disengage and pull out the second locking block to unlock the second buckle. Disassembly and installation are convenient.

[0013] In summary, the beneficial technical effects of this utility model are as follows:

[0014] 1. The first snap-fit, electrical connection groove and first clip are adopted, which makes the installation convenient and effectively improves the efficiency of connecting and installing a large number of wires to the female end;

[0015] 2. The adoption of a second buckle, a movable groove, and a second locking block further enhances the connection strength between the wire and the female end;

[0016] 3. It adopts elastic locking hooks and locking protrusions, which makes disassembly and installation convenient. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] 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.

[0025] Please see Figure 1-4 The present invention provides the following technical solution:

[0026] The device includes a conductor end 1 and a female end 2. The conductor end 1 includes several conductors 11. The female end 2 has an electrical connection groove 3 that mates with the conductors 11. A first buckle 4 is fixedly connected to the end of each conductor 11. A first locking block 5 that mates with the first buckle 4 is fixedly provided in the electrical connection groove 3. An elastic metal sheet 41 extends from the outer wall of the first buckle 4. The first locking block 5 abuts against the end of the elastic metal sheet 41. There are several conductors 11. The number of electrical connection grooves 3 matches the number of conductors 11. The first buckle 4 is installed by mates with the electrical connection groove 3 and the first locking block 5. In use, the first buckle 4 is inserted into the electrical connection groove 3 to achieve an electrical connection. After the clip 4 is in place, the elastic metal piece 41 automatically springs up to abut against the first locking block 5, thus locking the wire 11 in place. During installation, simply insert the first clip 4 directly into the designated position of the electrical connection slot 3 to quickly lock the wire 11 in place. Compared to the bolt tightening method, the clip-on connection of the elastic metal piece 41 has a significantly more convenient installation effect. When installing a large number of wires 11, the overall installation efficiency is much higher than that of traditional bolt-fixed connectors, effectively improving the efficiency of equipment use. During disassembly, pressing the elastic metal piece 41 to disengage it from the first locking block 5 will unlock and remove the wire 11.

[0027] A second buckle 6 is fixedly installed on the outer wall of the first buckle 4 near the wire 11. A movable groove 7, aligned with the second buckle 6, is opened through the outer wall of the female end 2. A second locking block 8, embedded in the movable groove 7, is engaged on the outer wall of the female end 2. An engagement area is opened on the inner wall of the second buckle 6, spaced apart from the movable groove 7. The second locking block 8 is embedded in the engagement area and abuts against the second buckle 6. The second buckle 6, in conjunction with the movable groove 7 and the second locking block 8, provides a double-locking and fixing function for the wire 11. In use, first, the first buckle 4 is inserted into the electrical connection groove 3, at which point the movable groove 7 aligns with the second buckle 6. Then, the second locking block 8 is engaged and installed, embedding the second locking block 8 into the movable groove 7, and then further embedded into the engagement area. When the wire 11 is pulled, the second locking block 8 will abut against the second locking buckle 6, preventing the wire 11 from falling off under external force, and further improving the connection between the wire 11 and the female end 2. The second locking buckle 6 can be either an elastic metal sheet 41 or a fixed block. When both the first locking buckle 4 and the second locking buckle 6 are elastic metal sheets 41, pulling the wire 11 will cause the first locking buckle 4 to slide slightly adaptively, which plays a good buffering role and prevents the wire 11 from falling off due to excessive pulling force in a short period of time. When the second locking buckle 6 is a fixed block, the firm abutment prevents the first locking buckle 4 from being pulled off by the elastic metal sheet 41, making the connection more stable and the tensile strength greater. The required locking buckle form can be selected according to the actual situation.

[0028] The second locking block 8 is set to fit against the top wall of the female end 2. Both ends of the second locking block 8 are provided with elastic locking hooks 9 that fit against the side walls of the female end 2. The outer wall of the female end 2 has a locking protrusion 91 that cooperates with the elastic locking hook 9. The elastic locking hook 9 and the locking protrusion 91 have a good locking effect. Pressing the second locking block 8 causes the elastic locking hook 9 to slide against the side wall of the female end 2 until the elastic locking hook 9 hooks onto the locking protrusion 91. At this time, the second locking block 8 is fully embedded into the locking area through the movable groove 7. When disassembling, pry the elastic locking hook 9 to disengage and pull out the second locking block 8 to unlock the second buckle 6. Disassembly and installation are convenient.
