Description

Technical Field

[0001] This utility model relates to wire harness connector technology, and in particular to an unshielded wire harness connector with a wire harness anti-reverse structure. Background Technology

[0002] In shielded wire harness connectors, the wire harness anti-reverse function is usually achieved by limiting the shielding ring. The shielding ring consists of an inner shielding ring and an outer shielding ring. During installation, the outer insulation layer of the shielded cable must first be stripped to expose the shielding layer. After that, the shielding layer is unfolded and folded over the outside of the inner shielding ring. Then, the outer shielding ring is crimped to the inner ring and fixed to the shielded cable. In this way, the anti-reverse function is achieved by limiting the shielding ring.

[0003] However, unshielded wire harnesses only contain conductors and insulation layers, lacking a shielding structure, making it impossible to install the aforementioned shielding ring. This results in unshielded wire harness connectors lacking an effective anti-retraction structure, making the wire harness susceptible to displacement or even detachment under tensile forces during use, affecting connection stability and operational safety. Existing technologies struggle to solve this problem.

[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design an unshielded wire harness connector with a wire harness anti-reverse structure to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an unshielded wire harness anti-reverse connector that can reliably prevent unshielded wire harnesses from reversing without relying on a shielding ring, thereby improving connection stability.

[0006] To achieve the above and other related objectives, the technical solution provided by this utility model is: an unshielded wire harness connector with a wire harness anti-reverse structure, comprising:

[0007] A housing having a through-cavity extending from front to back;

[0008] Terminal, wherein the terminal is disposed at the front section of the accommodating cavity;

[0009] A wire harness, wherein the wire harness is disposed in the rear section of the accommodating cavity, and the wire harness is connected to the terminal;

[0010] An anti-reverse component is fixed on the wire harness and is located at the rear end of the receiving cavity;

[0011] An end cap is fitted onto the wire harness and fixedly connected to the housing, thereby sealing the rear end of the accommodating cavity.

[0012] A preferred technical solution is as follows: an annular protrusion is formed in the accommodating cavity, the front end of the anti-retraction member abuts against the annular protrusion, and the rear end of the anti-retraction member abuts against the end cap.

[0013] The preferred technical solution is as follows: the anti-reverse component is an annular rubber body structure, and the inner ring of the anti-reverse component is provided with at least one set of annular protrusions, the inner diameter of the annular protrusions being smaller than the outer diameter of the wire harness.

[0014] The preferred technical solution is that the outer ring of the anti-reverse component is provided with at least one set of annular protrusions, and the outer diameter of the annular protrusions is larger than the inner diameter of the rear section of the accommodating cavity.

[0015] The preferred technical solution is that the end cap and the housing are fastened together by a snap-fit ​​structure. The snap-fit ​​structure consists of a snap hole formed on the end cap and a snap point formed on the housing. The snap hole and the snap point are matched and matched accordingly.

[0016] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0017] Without relying on shielding rings, reliable backlash prevention of unshielded wire harnesses is achieved through the cooperation of backlash prevention components with the receiving cavity and end caps, solving the backlash prevention problem caused by the inability to install shielding rings on unshielded wire harnesses due to the lack of shielding layer.

[0018] The inner ring of the anti-backlash component has an interference fit with the unshielded wire harness, and the outer ring has an interference fit with the inner wall of the receiving cavity. This double anti-slip limit provides a stable anti-backlash effect, effectively resists pulling force, and has a certain degree of waterproof performance.

[0019] The end cap and the housing are fixed by a snap-fit ​​structure, which makes assembly simple and can provide axial limit for the anti-reverse component, further improving the reliability of the anti-reverse component;

[0020] It has a compact structure, requires no additional complex components, has low production costs, and is suitable for installation scenarios of existing unshielded wire harnesses. Attached Figure Description

[0026] Example:

[0027] like Figures 1 to 2 As shown, according to a general technical concept of this utility model, an unshielded wire harness connector with a wire harness anti-reverse structure is provided, comprising:

[0028] The housing 1 has a cavity 11 that extends through the front and back.

[0029] Terminal 2 is located at the front of the accommodating cavity 11;

[0030] The wire harness 3 is located at the rear section of the accommodating cavity 11 and is connected to the terminal 2.

[0031] Anti-reverse component 4 is fixed on wire harness 3 and is located at the rear section of accommodating cavity 11;

[0032] End cap 5 is fitted onto wire harness 3 and fixedly connected to housing 1. End cap 5 seals the rear end of accommodating cavity 11.

[0033] like Figures 1 to 2As shown, in an exemplary embodiment of the present invention, an annular protrusion 111 is formed in the accommodating cavity 11, the front end of the anti-retraction member 4 abuts against the annular protrusion 111, and the rear end of the anti-retraction member 4 abuts against the end cap 5.

[0034] like Figures 1 to 2 As shown, in an exemplary embodiment of this utility model, the anti-reverse member 4 is an annular rubber body structure, and the inner ring of the anti-reverse member 4 is provided with at least one set of annular protrusions 41, the inner diameter of the annular protrusions 41 being smaller than the outer diameter of the wire harness 3.

[0035] like Figures 1 to 2 As shown, in an exemplary embodiment of this utility model, the outer ring of the anti-retraction member 4 is provided with at least one set of annular protrusions 42, and the outer diameter of the annular protrusions 42 is larger than the inner diameter of the rear section of the accommodating cavity 11.

[0036] like Figures 1 to 2 As shown, in an exemplary embodiment of this utility model, the end cap 5 and the housing 1 are fastened together by a snap-fit ​​structure. The snap-fit ​​structure consists of a snap hole 51 formed on the end cap 5 and a snap point 12 formed on the housing 1, with the snap hole 51 and the snap point 12 being matched and matched accordingly.

[0037] The assembly process of this embodiment is as follows: First, fix terminal 2 to the front section of the accommodating cavity 11 of housing 1; then, put the anti-retraction member 4 on the preset position of unshielded wire harness 3, and fix the anti-retraction member 4 and wire harness 3 through the interference fit of the annular protrusion 41; insert the unshielded wire harness equipped with anti-retraction member 4 into the rear section of accommodating cavity 11, so that the front end of anti-retraction member 4 abuts against the annular protrusion 111, and at the same time, the front end of unshielded wire harness 3 is electrically connected to terminal 2; finally, put end cap 5 on unshielded wire harness 3, push end cap 5 so that the buckle hole 51 is engaged and fixed with the buckle point 12 of housing 1, at this time the front end of end cap 5 presses against the rear end of anti-retraction member 4, and the assembly is completed.

[0038] When in use, if the unshielded wire harness 3 is subjected to a backward pulling force, the wire harness 3 will drive the anti-reverse member 4 to move backward. However, the rear end of the anti-reverse member 4 is blocked by the end cap 5. At the same time, the friction between the annular protrusion 42 and the inner wall of the accommodating cavity 11, and the clamping force between the annular protrusion 41 and the wire harness 3 work together to effectively prevent the wire harness 3 from moving backward and ensure a stable connection.

[0039] Therefore, this utility model has the following advantages:

[0040] Without relying on shielding rings, reliable backlash prevention of unshielded wire harnesses is achieved through the cooperation of backlash prevention components with the receiving cavity and end caps, solving the backlash prevention problem caused by the inability to install shielding rings on unshielded wire harnesses due to the lack of shielding layer.

[0041] The inner ring of the anti-backlash component has an interference fit with the unshielded wire harness, and the outer ring has an interference fit with the inner wall of the receiving cavity. This double anti-slip limit provides a stable anti-backlash effect, effectively resists pulling force, and has a certain degree of waterproof performance.

[0042] The end cap and the housing are fixed by a snap-fit ​​structure, which makes assembly simple and can provide axial limit for the anti-reverse component, further improving the reliability of the anti-reverse component;

[0043] It has a compact structure, requires no additional complex components, has low production costs, and is suitable for installation scenarios of existing unshielded wire harnesses.

[0044] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
