Description

Technical Field

[0001] This invention belongs to the field of connector technology, specifically relating to connectors that are easy to assemble and disassemble, connector application methods, and connector assemblies. Background Technology

[0002] A wire connector is a component used to connect electrical equipment or units to power / signal wires. It typically includes a connector body, multiple connection terminals mounted inside the connector body, and a connector cover for securing the connection terminals.

[0003] In existing technologies, when installing terminals inside the connector body, a protruding spring is typically machined on the outer surface of the terminal. This spring forms a hook structure with the terminal, which then engages with the connector body to secure the terminal. However, during use, the terminals are frequently inserted and removed from their mating ends, which can lead to wear or elastic fatigue of the spring, causing the hook structure to lose its holding force on the terminal. This results in the terminals inside the connector body becoming loose, affecting the connector's operational stability. Furthermore, existing terminals are difficult to remove after installation; they must be pulled out through the terminal's connector end, which can cause excessive force on the connector end and lead to loosening.

[0004] Therefore, there is an urgent need for a wire-end connector with strong holding force and easy disassembly and assembly to meet the requirements for disassembly, assembly, and locking. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, the present invention provides a connector that is easy to assemble and disassemble, a connector application method, and a connector assembly, in order to solve the problem that in the prior art, the terminals are fixed to the connector body only by the hook structure formed by the spring, which easily leads to wear or elastic fatigue of the spring during repeated insertion and removal, resulting in the failure of the holding force of the hook structure on the terminals.

[0057] Please refer to Figures 1-5 , Figure 8 One embodiment of the present invention provides a connector that is easy to assemble and disassemble, including an inner terminal 1, a connector body 2, and a terminal locking module 3;

The first clamping part 11 is sleeved with an outer terminal 14 to form a double-layer terminal structure. The outer terminal 14 and the tightening part 13 constitute a limiting structure. The second clamping part 12 is used to clamp the connecting wire.

[0059] The connector body 2 is provided with a terminal mounting groove 21, the inner terminal 1 is accommodated and installed in the terminal mounting groove 21, and a locking point structure 22 is provided in the terminal mounting groove 21 for positioning the limiting structure;

[0060] The terminal locking module 3 is detachably mounted on the connector body 2. The bottom of the terminal locking module 3 is provided with an insert 36. The position of the insert 36 corresponds to the position of the locking point structure 22. The insert 36 and the locking point structure 22 form an annular interference structure for fixing the inner terminal 1.

[0061] The terminal mounting groove 21 is also provided with an ejection hole 23 at its bottom.

[0062] The connector that is easy to assemble and disassemble provided by the above solution of the present invention has the following beneficial effects:

[0063] 1. The double-layer terminal structure formed by the outer terminal 14 and the inner terminal 1 prevents fatigue and ineffective contact caused by excessive expansion when the inner terminal 1 is mated with the mating end (such as the pin 5);

[0064] 2. A limiting structure is formed by the outer terminal 14 and the tightening part 13 on the inner terminal 1. The limiting structure replaces the traditional hook structure. The limiting structure is positioned by the locking point structure 22, which enhances the holding force between the inner terminal 1 and the connector body 2.

[0065] 3. An ejection hole 23 is provided at the bottom of the terminal mounting groove 21 used to fix the inner layer terminal 1. The position of the ejection hole 23 corresponds to the double-layer terminal structure. When it is necessary to remove the inner layer terminal 1, the inner layer terminal 1 fixed by the locking structure 22 can be easily pried up and removed through the ejection hole 23, which facilitates the disassembly and assembly of the inner layer terminal 1. At the same time, it effectively reduces the situation where the wiring terminal of the inner layer terminal 1 used to install the wiring material is subjected to excessive force, which may easily lead to loose wiring.

[0066] Please refer to Figure 3In one application scenario of this embodiment, the inner diameter of the tightening part 13 is smaller than the inner diameter of the first clamping part 11 and the inner diameter of the second clamping part 12; wherein, the tightening part 13 is used to clamp the mating end (such as the pin 5) so that when energized, the tightening part 13 is electrically connected to the mating end (such as the pin 5), thereby electrically connecting the mating end (such as the pin 5) to the connecting wire through the inner terminal 1.

[0067] In one application scenario of this embodiment, the outer terminal 14 is made of stainless steel; the inner terminal 1 is made of copper alloy, which has good elasticity and conductivity.

[0068] Please refer to Figure 3 In one embodiment of the present invention, a guide portion 141 is provided at one end of the outer terminal 14, and a stop portion 142 is provided at the other end of the outer terminal 14. The guide portion 141 is used to guide the first clamping portion 11 from one end of the outer terminal 14 into the outer terminal 14, and the stop portion 142 is used to prevent the first clamping portion 11 from extending from the other end of the outer terminal 14.

[0069] The outer terminal 14 is fixedly connected to the first clamping part 11.

[0070] In this embodiment, the guide portion 141 and the stop portion 142 are used to limit the first clamping portion 11 to prevent the first clamping portion 11 from extending from the other end of the outer terminal 14 during the assembly process, thereby improving production efficiency and overall stability; and after the outer terminal 14 is assembled on the first clamping portion 11, a laser welding point is formed between the outer terminal 14 and the first clamping portion 11 by laser welding, so that the outer terminal 14 and the first clamping portion 11 are fixedly connected.

[0071] Please refer to Figures 4-5 In one embodiment of the present invention, the locking structure 22 includes a locking base 221 and an arc-shaped locking point 222. The locking base 221 has an arc-shaped mounting groove 223, which is used to support the tightening part 13. The two arc-shaped locking points 222 are respectively disposed on the two side walls of the arc-shaped mounting groove 223. The arc-shaped locking point 222 is an elastic protrusion or elastic protrusion that can undergo elastic deformation. The arc-shaped locking point 222 is used to clamp and position the tightening part 13 in the arc-shaped mounting groove 223.

[0072] The end face of the locking base 221 abuts against the guide portion 141 to lock and position the outer terminal 14.

[0073] In this embodiment, since the arc-shaped locking point 222 is an elastic protrusion or elastic block that can undergo elastic deformation, when installing the inner layer terminal 1, pressing the inner layer terminal 1 causes the arc-shaped locking point 222 to undergo elastic deformation, so that the inner layer terminal 1 passes through the arc-shaped locking point 222 and enters the arc-shaped mounting groove 223. After the inner layer terminal 1 is installed, the arc-shaped locking point 222 effectively clamps and positions the tightening part 13 in the arc-shaped mounting groove 223, preventing the inner layer terminal 1 from loosening and coming out.

[0074] Furthermore, by abutting the end face of the locking base 221 against the guide portion 141, the outer terminal 14 is locked and positioned on the side of the locking structure 22 facing the mating end (such as the pin 5), thereby causing the locking structure 22 to interfere with the outer terminal 14, thereby enhancing the holding force of the inner terminal 1 in the terminal mounting groove 21.

In this embodiment, the positioning relationship between the guide block 31 and the guide hole 24 facilitates the positioning and installation of the terminal locking module 3 on the connector body 2.

[0076] Please refer to Figure 6 In one embodiment of the present invention, the terminal locking module 3 is provided with a process groove 32 at the other end away from the guide block 31. The notch formed by the process groove 32 corresponds to the position of the anti-sliding block on the connector body 2 and is used for positioning the terminal locking module 3 in the recess. In this embodiment, the process groove 32 cooperates with the anti-sliding block on the connector body 2 to prevent the terminal locking module 3 from shifting left and right.

[0077] Please refer to Figure 6 In one embodiment of the present invention, locking grooves 25 are provided on both sides of the recess, and locking blocks 33 are provided on both sides of the terminal locking module 3. The locking blocks 33 are snapped into the locking grooves 25.
