Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to a highly stable detachable wire-end connector. Background Technology

[0002] In fields such as electronic equipment, industrial control, automotive electronics, and communication equipment, connectors are core components that enable circuit conduction, signal transmission, or power supply. Their performance directly determines the overall stability, reliability, and lifespan of the equipment. As these fields rapidly develop towards miniaturization, integration, and high power, the requirements for connectors have gradually upgraded from basic electrical connection functions to multiple high-specification requirements for structural strength (especially tensile strength), contact stability, and adaptability flexibility.

[0003] Chinese patent CN223156308U discloses a double-arm terminal and connector. This double-arm terminal, by providing elastic arms on both sides of the contact point, allows for a greater contact force when abutting against the rigid terminal of the male connector. This reduces connection resistance, lowers fatigue risk, and improves stability. However, this terminal and connector only provides contact force through a single-layer double-arm terminal, resulting in low tensile strength of the arms. After prolonged use, metal fatigue can easily occur, leading to unstable connections.

[0004] Therefore, a highly stable detachable connector is needed to solve the above problems. Utility Model Content

[0021] The following description, in conjunction with the accompanying drawings, details a specific solution for a highly stable detachable wire-end connector provided by this utility model.

[0022] Please refer to Figures 1 to 4 A highly stable detachable wire-end connector includes a plurality of crimp terminals 1 and an insulating element 2 coupled to the plurality of crimp terminals 1.

[0023] Please refer to Figure 1The number of crimp terminals 1 can be changed according to requirements. In this embodiment, the crimp terminals 1 are 24 pins and are arranged in two rows along the longitudinal direction. The upper row of crimp terminals 1 are 8 pins and are fixed to the top two sides by the insulating member 2 respectively.

The pair of first sidewalls 112 extend in different directions and form an angle with the fixed section body 111.

[0026] The contact segment 12 includes a contact segment body 121, a first rolled edge 122 located on one side of the rear section of the contact segment body 121, and a second rolled edge 123 located on the other side of the contact segment body 121.

One end of the first rolled edge 122 is connected to the contact segment body 121, and the other end is bent to the bottom of the contact segment body 121. One end of the second rolled edge 123 is connected to the contact segment body 121, and the other end is bent to the bottom of the first rolled edge 122. The contact segment body 121, the first rolled edge 122, and the second rolled edge 123 surround to form a contact cavity 124.

[0027] Specifically, the front end of the first rolled edge 122 forms a first elastic portion 125, the first elastic portion 125 extends along the contact cavity 124 and its end extends into the contact cavity 124, the front end of the second rolled edge 123 forms a second elastic portion 126, the second elastic portion 126 is located below the first elastic portion 125, it extends along the first elastic portion 125 and its end abuts against the first elastic portion 125.

[0028] Furthermore, the front end of the contact segment body 121 is provided with a third rolled edge 127.

The deformable segment body 131 is stamped to form an arc-shaped structure. A pair of second sidewalls 132 extend obliquely from the sides of the deformable segment body 131 respectively. The pair of second sidewalls 132 extend in different directions and form an angle with the deformable segment body 131.

[0030] The crimp terminal 1 has a window 14 that extends through the upper and lower surfaces of the contact section body 121 and communicates with the contact cavity 124.

[0031] Preferably, a notch 15 is formed at the connection between the fixed section 11 and the contact section 12 and the deformation section 13, and the notch 15 facilitates the stamping of the contact section 12 and the deformation section 13.

[0032] The insulating component 2 includes an integrally formed base 21 and a tongue plate 22 extending outward from the front end of the base 21.

[0033] Please refer to Figure 4 The tongue plate 22 has several longitudinally arranged receiving cavities 23, which penetrate the front and rear surfaces of the insulating member 2. The crimping terminals 1 are installed one by one in the several receiving cavities 23.

[0034] The insulating member 2 includes a mounting groove 24 recessed inward from the bottom surface, which communicates with the upper and lower rows of receiving cavities 23. A positioning member 25 is provided in the mounting groove 24. The positioning member 25 has a through hole 251 penetrating its front and rear surfaces. The positioning member 25 is fixed in the mounting groove 24. The through hole 251 is connected to the receiving cavity 23 in the lower row. The top of the positioning member 25 corresponds to the receiving cavity 23 in the upper row. The positioning member 25 also has a protrusion 252, which extends upward from the inner wall of the through hole 251 and the top surface of the positioning member 25.

[0035] The mounting groove 24 divides the receiving cavity 23 into a front section and a rear section. A step 28 is provided in the front section of the receiving cavity 23, corresponding to a protrusion 252. A contact section 12 is located within the front section of the receiving cavity 23 and its position is limited by the step 28 and the protrusion 252. A fixing section 11 and a deformable section 13 are located within the through hole 251 formed by the rear section of the receiving cavity 23 and the positioning member 25, and at the top of the positioning member 25.

One end of the elastic arm 27 is fixedly connected to the insulating member 2, and the other end extends into the clearance groove 26, enters the window 14, and abuts against the contact section body 121.

[0037] When using this highly stable detachable connector, when an external plug is inserted into the connector interface, the plug's contact structure first enters the semi-enclosed contact space 128 of the contact section 12, and then extends into the contact cavity 124. During this process, the third elastic part 129 and the first elastic part 125 undergo elastic deformation under the pressure of the plug, while the second elastic part 129 provides a reverse support force to the first elastic part 125, so that the three elastic parts together tightly abut against the plug contact structure. Through the crimping / welding of the deformation section 13 with the substrate or circuit, the arc-shaped structure of the deformation section body 131 and the second sidewall 124 are utilized. The bending adaptability of 32 enables a firm connection between the terminal and the substrate / circuit. At the same time, the arc-shaped structure of the fixing section 11 and the first sidewall 112 further enhance the tensile strength of the terminal within the insulation, preventing the terminal from being pulled out during docking. When the connector interface is subjected to a pulling force, on the one hand, the first sidewall 112 of the fixing section 11, the retaining part 29 of the rear section of the receiving cavity 23, the step of the contact section 12, and the protrusion 252 of the positioning member 25 form multiple limits to prevent the terminal from being pulled out of the insulation. On the other hand, the elastic arm 27 further disperses the pulling force by resisting the contact section body 121 through the window 14.

[0038] This utility model is a highly stable detachable wire terminal connector. It has the characteristic of stability. The elastic part formed by multiple rolled edges ensures a tight fit with the plug contact structure, improving the connection stability. Combined with the design of multiple limiting of the insulating part and elastic arm to disperse the pulling force, the connector interface can better resist the pulling force when subjected to external pulling force, preventing the terminal from coming out of the insulating part.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the principles of the present utility model should be included within the protection scope of the present utility model.
