Description

Technical Field

[0001] This utility model relates to the field of electrical connector design and manufacturing technology, specifically to a wire harness connector. Background Technology

[0002] Connectors are components frequently encountered by electronic engineers. Their primary function is to bridge gaps in circuits or connect isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. The basic structure of a connector includes: contacts or terminals, insulators, and a housing. Terminals are accessories used for electrical connections, bridging gaps in circuits or connecting isolated circuits to allow current to flow and enable the circuit to perform its intended function. Conventionally, the electrical connection between the connector tail and the bare wire bundle is achieved through manual soldering followed by manual application of heat shrink tubing. This method has disadvantages such as low production efficiency, environmental unfriendliness, high soldering costs, high labor costs, and the inability to fully guarantee soldering reliability based on manual skill. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a wire harness connector to solve the problem of low production efficiency caused by manual soldering and material addition mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts a wire harness connector, comprising:

[0005] A male plug and a female plug are arranged opposite each other along a first direction. The female plug has a slot on the side facing the male plug along the first direction for insertion and mating with the male plug. The top of the male plug has a first groove, and the top of the slot has a second groove corresponding to the first groove.

[0006] The self-locking assembly includes a first connecting plate and a second connecting plate. The first connecting plate is disposed within a first groove, and its end along the first direction away from the female plug is connected to the male plug. The second connecting plate is disposed within a second groove, and its end along the first direction away from the male plug is connected to the female plug. A limiting protrusion is provided on the top of the first connecting plate, so that when the male plug and the female plug are inserted and engaged, the other end of the second connecting plate along the first direction abuts against the other end of the first connecting plate along the first direction. The limiting protrusion is positioned in the second groove and abuts against the female plug for limiting positioning.

[0007] The present invention provides a wire harness connector that adopts a plug-in connection method, which eliminates the need for welding or other complex operations, making installation and disassembly more convenient and significantly improving work efficiency. Through the design of the self-locking components (first connecting plate and second connecting plate), after the male plug and female plug are plugged in, the limiting protrusion abuts against the female plug to limit the connection, which can effectively prevent the connector from loosening under vibration or external force.

[0008] In some embodiments, the male plug has an insertion end and a fixing end sequentially along a first direction. The insertion end faces the female plug along the first direction and corresponds to the socket. A first groove is provided on the top of the insertion end. A transition step is provided at the connection between the insertion end and the fixing end. A limiting strip is provided on the side of the insertion end facing the female plug along the first direction, and the limiting strip extends along a second direction. The socket has a limiting groove corresponding to the limiting strip, which is used to limit the female plug by abutting against the limiting step after the insertion end is inserted into the socket. The limiting strip is fixed by cooperating with the limiting groove. The second direction is perpendicular to the first direction.

[0009] By adopting the above technical solution, the male plug and female plug can be mechanically limited after insertion through the interlocking of the limiting strip and the limiting groove, preventing the connector from loosening under vibration or external force, and further enhancing the stability of the connection.

[0010] In some embodiments, the male plug further includes a first mounting through hole and a metal male terminal. The first mounting through hole extends through the insertion end and the fixing end along the first direction, and the metal male terminal extends along the first direction and passes through the first mounting through hole. The two ends of the metal male terminal are respectively provided with a first connecting blind hole and a connecting guide post. The first connecting blind hole is used to connect a wire harness, and the connecting guide post is located on the side of the metal male terminal near the female plug and is arranged in a gap-like arc-shaped petal structure.

[0011] By adopting the above technical solution, the arc-shaped petal structure can increase the elasticity of the connecting guide post, better adapt to the slight deviations during the insertion and removal process, provide a more reliable electrical connection, and at the same time reduce friction during insertion and removal to ensure the stability of the connection.

[0012] In some embodiments, the female plug further includes a second mounting through hole and a metal female terminal. The second mounting through hole communicates with the socket along the first direction, and the metal female terminal extends along the first direction and passes through the first mounting through hole. The two ends of the metal female terminal are respectively provided with a second connecting blind hole and a third connecting blind hole. The second connecting blind hole is used to connect a wire harness, and the third connecting blind hole is located on the side of the metal female terminal near the male plug, so that when the insertion end is inserted and engaged with the socket, the third connecting blind hole is inserted and fixed to the connecting guide post.

[0013] Using the above technical solution, the metal female terminal of the female plug adopts the design of a second connection blind hole and a third connection blind hole. The third connection blind hole interferes with the connection guide post of the male plug, and the friction between the two is used to complete the tight fit to ensure the stability of the connection.

[0014] In some embodiments, a first annular limiting portion is provided within the first mounting through hole, and a male step portion is provided on the outer side of the male metal terminal. The male step portion is located between the first connecting blind hole and the connecting guide post, and is used to abut and fix with the first annular limiting portion. A second annular limiting portion is provided within the second mounting through hole, and a female step portion is provided on the outer side of the female metal terminal. The female step portion is located between the second connecting blind hole and the third connecting blind hole, and is used to abut and fix with the second annular limiting portion.

[0015] The above technical solution provides a dual limiting function through the design of the annular limiting part and the stepped part. The annular limiting part in the first mounting through hole abuts and fixes against the male stepped part of the male metal terminal, and the annular limiting part in the second mounting through hole abuts and fixes against the female stepped part of the female metal terminal. This structural design effectively prevents the terminals from loosening or shifting during installation, ensuring the stability of the connection.

[0016] In some embodiments, a first observation hole is provided on the outer side of the male metal terminal. The first observation hole is located on the outer side of the first blind connection hole and near the male step portion. A second observation hole is also provided on the outer side of the female metal terminal. The second observation hole is located on the outer side of the second blind connection hole and near the female step portion, and is used to confirm the installation position of the wire harness through the first observation hole and the second observation hole.

[0017] The above technical solution, with its observation hole design, makes the installation process more intuitive. Operators can directly observe the installation position of the wire harness inside the terminal, ensuring that the wire harness is correctly inserted and fixed in the blind hole, avoiding poor contact caused by incomplete insertion or misalignment of the wire harness, thereby reducing misoperation and rework.

[0018] In some embodiments, the wire harness connector further includes a wire harness sheath, which is respectively disposed at opposite ends of the male plug and the female plug along the first direction. The wire harness sheath includes a wire harness mounting hole and a connector portion. The wire harness mounting hole is disposed through the first direction, and the connector portion is disposed on the side of the wire harness sheath facing the male plug along the first direction. The wire harness mounting hole and the connector portion are correspondingly disposed with the first mounting through hole and the second mounting through hole, respectively, for inserting and fixing the wire harness sheath to the male plug and the female plug through the connector portion.

[0019] By adopting the above technical solution, the wire harness sheath is fixed by plugging and connecting with the male and female plugs through the connector, which can effectively prevent the wire harness from loosening under vibration or external force. The wire harness mounting holes and the connector are set to correspond with the mounting through holes of the connector, which ensures the stable installation of the wire harness, making the installation of the wire harness more convenient and quick, and reducing assembly time and labor costs.

[0020] In some embodiments, the outer surface of the connector is provided with a hook, and both the fixed end and the female plug are provided with a slot corresponding to the hook for engaging and fixing with the connector.

[0021] By adopting the above technical solution, the cooperation between the hook and the slot can ensure a firm connection between the wire harness sheath and the male and female plugs, effectively preventing the sheath from loosening under vibration or external force.

[0022] In some embodiments, the male plug, the female plug, and the wire harness sheath are arranged correspondingly along the first direction, with one side of the third direction being a right-angled bend and the other side being an obtuse-angled bend, and the first direction, the second direction, and the third direction being perpendicular to each other.

[0023] By adopting the above technical solution, the design of right-angle and obtuse-angle bends makes the structure of the wire harness connector clearer, and the asymmetrical structure facilitates foolproofing and increases the efficiency of installation and replacement.

[0024] In some embodiments, the male plug, the female plug, and the wire harness sheath are all made of plastic.

[0025] By adopting the above technical solution, plastic materials have a lower density than metal materials, which can significantly reduce the weight of the connector and lower production costs. In addition, the molding process of plastic materials is simple, and they have excellent electrical insulation properties, which can effectively prevent electrical short circuits and leakage, ensuring the safety of the connector in high-voltage or high-current environments, making them suitable for mass production.
