Description

Technical Field

[0001] This utility model relates to the field of wire harness connector technology, and in particular to a housing assembly and a wire harness connection device. Background Technology

[0002] Wire harness connectors are devices used in electronic equipment or electrical systems to safely and reliably connect multiple wires or cables to electrical components. They are widely used in the automotive industry, computer electronics, home appliances, and other fields requiring complex wiring. Connectors facilitate the insertion and removal of wires, simplifying installation, maintenance, and component replacement, while also ensuring the stability and safety of electrical connections.

[0003] Wire harness connectors typically consist of two parts: a male connector (pins) and a female connector (receptacle). These two parts are designed for precise mating to ensure good electrical contact and prevent loosening or disconnection. Both male and female connectors include a wire harness and a connector attached to the end of the harness. To adapt to different environmental conditions and requirements, wire harness connectors also need to be waterproof and dustproof. However, after the connector and wire harness are assembled, there is a risk of damage and failure at the connection point during subsequent handling and transportation. Therefore, it is necessary to design a housing assembly to address these technical issues. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a housing assembly and a wire harness connection device. By setting up a housing assembly and installing it at the connection point between the connector and the wire harness, the protection of the connector is strengthened, failure during handling and transportation is avoided, and product quality is improved.

[0005] The technical solution to achieve the purpose of this utility model is:

[0006] A housing assembly includes an upper shell and a lower shell disposed opposite to each other, the upper shell and the lower shell being detachably fixed together to form a receiving cavity that fits and surrounds the connection point of the connector and the wire harness. The receiving cavity is provided with a first limiting part and a second limiting part at the front end. The housing assembly limits the connector along the length direction of the wire harness through the first limiting part and the second limiting part.

[0007] Furthermore, the upper and lower shells have the same structure, with symmetrically arranged outwardly extending connecting parts on both sides. The connecting parts are pre-set with mounting holes, and the upper and lower shells are fixedly connected by bolts passing through the corresponding mounting holes and tightening.

[0008] Furthermore, the mating surface of either of the two interconnected connecting parts is provided with an outwardly protruding positioning post, and the other connecting part is provided with a positioning groove that matches the positioning post.

[0009] Furthermore, the inner walls of the upper and lower shells are provided with a protrusion extending to the rear end of the housing assembly. The bottom of the protrusion extends to the center surface of the housing assembly and is provided with an arc-shaped groove adapted to the wire harness.

[0010] Furthermore, both the connecting portion and the protrusion are provided with grooves.

[0011] Furthermore, the groove is provided with reinforcing ribs.

[0012] Furthermore, the inner walls of the upper and lower shells are provided with a first stepped surface to form a first limiting part.

[0013] Furthermore, the second limiting part includes buckles symmetrically disposed on both sides of the housing assembly. The buckles include a first plate and a second plate that are perpendicular to each other and have a rounded transition. The first plate extends along the side wall of the receiving cavity, and the second plate extends toward the center of the receiving cavity.

[0014] A wire harness connection device includes a wire harness and a connector fixedly connected to the end of the wire harness. A housing assembly as described above is fixedly installed at the connection point between the connector and the wire harness. The connector has a second stepped surface, a second limiting part is fitted to the front end of the second stepped surface, and a first limiting part is fitted to the rear end of the connector.

[0015] Furthermore, the gap between the receiving cavity and the connector is filled with waterproof sealant.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] (1) The housing assembly of this utility model adopts an upper and lower structure consisting of an upper shell and a lower shell, which can be directly installed at the connection point of the connector and the wire harness. It is easy to assemble. It is provided with a first limiting part and a second limiting part to restrict the forward and backward movement of the housing assembly relative to the connector, so that the housing assembly can remain fixed and thus protect the connection point, avoid failure during turnover and transportation, and improve product quality.

[0018] (2) The present invention uses bolts to fix the upper shell and the lower shell together, which is not only convenient to assemble, but also secure.

[0019] (3) By setting mutually compatible positioning pins and positioning slots, this utility model ensures the correct relative position between the upper and lower shells, improves assembly accuracy and simplifies the assembly process.

[0020] (4) By setting a protrusion and an arc groove on the protrusion, the contact area with the wire harness is increased, thereby better fixing the wire harness and improving the protection of the connection.

[0021] (5) By setting grooves, this utility model saves material usage of the shell components and reduces manufacturing costs.

[0022] (6) This utility model improves the overall structural strength by setting reinforcing ribs.

[0023] (7) This utility model further provides waterproof sealing at the connection by filling the gap between the receiving cavity and the connector with waterproof sealant, thereby avoiding the failure of some products to be waterproof or dustproof and eliminating potential quality and safety hazards.

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] (Example 1)

[0033] like Figures 1 to 3The wire harness connection device shown includes a wire harness 100 and a connector 200 fixedly connected to the end of the wire harness 100. A housing assembly 300 is fixedly installed at the connection point between the connector 200 and the wire harness 100. The housing assembly 300 includes an upper shell 1 and a lower shell 2 disposed opposite to each other. The upper shell 1 and the lower shell 2 are detachably fixed together to form a receiving cavity that fits and surrounds the connection point between the connector 200 and the wire harness 100. A first limiting part 3 is provided in the receiving cavity, and a second limiting part 4 is provided at the front end. A second stepped surface is provided on the connector 200. The second limiting part 4 fits and is disposed at the front end of the second stepped surface, and the first limiting part 3 fits and is disposed at the rear end of the connector 200. This achieves the fixed connection between the housing assembly 300 and the connector 200, thereby protecting the connection point, preventing failure during handling and transportation, and improving product quality.

[0034] Specifically, the upper shell 1 and lower shell 2 have identical structures, with symmetrically arranged outwardly extending connecting parts 5 on both sides. Each connecting part 5 has a pre-set mounting hole 6. The upper shell 1 and lower shell 2 are fixedly connected by bolts passing through the corresponding mounting holes 6 and tightening them, ensuring both convenient assembly and a secure connection. The mounting holes 6 are countersunk holes, ensuring a smooth surface and a more aesthetically pleasing appearance. Each of the two interconnected connecting parts 5 has an outwardly protruding positioning post 7 on its mating surface, and the other connecting part 5 has a positioning groove 8 that matches the positioning post 7, ensuring the correct relative position between the upper and lower shells, improving assembly accuracy while simplifying the assembly process.

[0035] The inner walls of the upper shell 1 and the lower shell 2 are provided with a first stepped surface to form a first limiting part 3. The second limiting part 4 includes buckles symmetrically arranged on both sides of the shell assembly. The buckles include a first plate 4-1 and a second plate 4-2 that are perpendicular to each other and have a rounded transition. The first plate 4-1 extends forward along the side wall of the receiving cavity, and the second plate 4-2 extends toward the center of the receiving cavity.

[0036] The inner rear wall of the upper shell 1 and the lower shell 2 is provided with a protrusion 9 extending to the rear end of the shell assembly. The bottom of the protrusion 9 extends to the center surface of the shell assembly and is provided with two arc-shaped grooves 9-1 that are adapted to the two wire harnesses, thereby increasing the contact area with the wire harnesses, better fixing the wire harnesses, and improving the protection of the connection.

[0037] Both the connecting part 5 and the protrusion 9 are provided with grooves 10, which saves material usage in the housing assembly and reduces manufacturing costs. Reinforcing ribs 11 are provided inside the grooves 10 to improve the overall structural strength.

[0038] Considering that the waterproof function of some products may fail after the connector 200 and wire harness 100 are assembled, which is difficult to identify from the appearance, this embodiment fills the gap between the receiving cavity and the connector with waterproof sealant, thereby eliminating the problem of waterproof failure and further improving the quality of the product.

[0039] The housing assembly of this utility model adopts an upper and lower structure consisting of an upper shell 1 and a lower shell 2. It can be directly installed at the connection point of the connector 200 and the wire harness 100, which is convenient for assembly. It is provided with a first limiting part 3 and a second limiting part 4 to restrict the forward and backward movement of the housing assembly relative to the connector, so that the housing assembly can remain fixed and thus protect the connection point, avoid failure during turnover and transportation, and improve product quality.

[0040] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
