Molded wire harness connector

Abstract

This utility model discloses a molded wire harness connector, comprising a housing, wire harness terminals, connecting wires, and injection-molded blocks. The housing includes a receiving portion, a retaining plate, and a socket portion. The front end of the wire harness terminal is located in the receiving hole of the receiving portion, and the rear end is located in the socket hole of the socket portion and connected to the connecting wire. The injection-molded blocks cover the socket portion and are injected into the socket holes. This utility model has a reasonable structural design. After assembling the wire harness terminals with connecting wires, PVC or other plastics are directly injection-molded onto the socket portion to form an injection-molded block. Compared with the traditional method of wrapping with cloth-based adhesive tape or electrical tape, the injection-molded block is tightly integrated with the socket portion, forming a whole, with better sealing effect. When foam is used for fixing, the injection-molded block can effectively prevent foam from entering the socket hole of the wire harness connector, reducing the risk of poor contact between the male and female wire harness connectors due to foam seepage, and ensuring the normal operation of household appliances.

Description

Technical Field

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

[0002] In home appliances such as washing machines and refrigerators, wire harness connectors are typically used to connect various functional modules. After connection, they need to be secured inside the appliance housing with expanding foam. To prevent expanding foam from entering the connector sockets, the traditional method is to wrap cloth tape or electrical tape around the socket for sealing. While this achieves a certain sealing effect, the cloth tape or electrical tape may come undone if the operator does not wrap it tightly enough. This allows expanding foam to easily enter the connector, leading to poor contact between the male and female wire harness connectors and affecting the normal operation of the appliance. Utility Model Content

[0003] To address the aforementioned shortcomings, the purpose of this utility model is to provide a molded wire harness connector with a reasonable structural design and good packaging effect.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] A molded wire harness connector includes a housing, wire harness terminals, connecting wires, and an injection-molded block. The housing has a insertion portion at its front end, a radially enlarged baffle at its middle position, and a socket portion at its rear end. The insertion portion has a insertion hole, and the socket portion has a socket hole. The front end of the wire harness terminal is located in the insertion hole, and the rear end is located in the socket hole. The connecting wire is inserted into the socket hole and connected to the rear end of the wire harness terminal. The injection-molded block covers the socket portion and is injected into the socket hole.

[0006] As a preferred embodiment of this utility model, the cross-sectional profile of the socket is square, and the corners of the socket are provided with raised strips to enhance the structural strength of the socket and increase the contact area.

[0007] As a preferred embodiment of this utility model, the outer wall of the sleeve is provided with barbs, which fit tightly with the injection-molded block.

[0008] In a preferred embodiment of this invention, the tail end face of the socket is provided with a dividing protrusion. The dividing protrusion can separate and guide multiple connecting wires extending from the socket hole.

[0009] In a preferred embodiment of this invention, the edge of the baffle protrudes to form a tilting portion. This provides the operator with a more convenient point of leverage, facilitating quick installation or disassembly.

[0010] As a preferred embodiment of this utility model, the edge of the baffle is recessed to form a positioning groove, thereby enabling rapid and accurate positioning and installation of the wire harness connector.

[0011] As a preferred embodiment of this utility model, the back of the baffle is provided with several reinforcing ribs, one end of each reinforcing rib is connected to the sleeve portion, and the other end extends along the radial direction of the baffle, effectively enhancing the overall structural strength of the wire harness connector.

[0012] As a preferred embodiment of this utility model, foam is attached to the front edge of the baffle to enhance the sealing effect.

[0013] As a preferred embodiment of this utility model, the tail end of the injection-molded block protrudes downward to form a bent portion, and a bend is formed in the bent portion for the connecting line to bend, providing a more reasonable bending path for the connecting line.

[0014] The beneficial effects of this utility model are as follows: The structure of this utility model is reasonably designed. After assembling the wire harness terminals with connecting wires, PVC or other plastic injection molding blocks are directly formed on the socket part. Compared with the traditional method of wrapping cloth-based adhesive tape or electrical tape, the injection molding blocks are tightly combined with the socket part to form a whole, and the sealing effect is better. When foaming is used for fixing, the injection molding blocks can effectively prevent the foaming adhesive from entering the socket hole of the wire harness connector, reducing the risk of poor contact between the male and female wire harness connectors due to foaming adhesive seepage, and ensuring the normal operation of home appliances.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0022] Example 1, see Figures 1 to 4 This embodiment provides a molded wire harness connector, which includes a housing 1, a wire harness terminal 2, a connecting wire 3, and an injection molded block 4.

[0023] The front end of the housing 1 is provided with a connector 11. Taking the male wire harness connector as an example in this patent, the connector 11 is used for female wire harness connector connection. Conversely, the connector 11 is used for male wire harness connector connection.

[0024] The middle position of the insert 1 is radially enlarged to form a retaining plate 12. Preferably, a plurality of reinforcing ribs 121 are provided on the back of the retaining plate 12. One end of each reinforcing rib 121 is connected to the socket 13, and the other end extends radially along the retaining plate 12, providing additional support for the retaining plate 12. This makes the retaining plate 12 less prone to deformation under external force, enhancing the overall structural strength of the wire harness connector, protecting the connection stability of the wire harness terminal 2 and the connecting wire 3, and extending the service life of the connector. Preferably, the edge of the retaining plate 12 protrudes to form a tilting part 122. This provides a more convenient point of leverage for the operator. When the retaining plate 12 is engaged with the appliance housing or other components, it is easier for the operator to fix or adjust the wire harness connector. The tilting part 122 can easily change the contact state between the retaining plate 12 and the mating surface, achieving quick installation or disassembly and improving work efficiency.

[0025] The end of the insert 1 is provided with a sleeve part 13. Specifically, the cross-sectional profile of the sleeve part 13 is preferably square, and the corners of the sleeve part 13 are provided with protrusions 131, which increases the structural strength of the sleeve part 13 and also increases the contact area with the injection molded block 4, resulting in a more solid bonding effect.

[0026] The connector 11 is provided with a connector hole 111, and the socket 13 is provided with a socket hole 132. The front end of the wire harness terminal 2 is located in the connector hole 111, and the tail end is located in the socket hole 132. The connecting wire 3 is inserted into the socket hole 132 and connected to the tail end of the wire harness terminal 2.

[0027] After assembling the wire harness terminal 2 with connecting wire 3, a PVC or other plastic injection molding block 4 is directly formed on the socket 13, so that the injection molding block 4 covers the socket 13 and is injected into the socket hole 132. Preferably, the tail end of the injection molding block 4 protrudes downward to form a bending part 41, and a bend 411 is formed in the bending part 41 for the connecting wire 3 to bend, which provides a more reasonable bending path for the connecting wire 3, prevents the connecting wire 3 from being excessively bent, twisted or broken during bending, reduces bending fatigue of the connecting wire 3 and extends its service life.

[0028] During assembly, an opening slightly larger than the connector 11 is pre-drilled on the motor housing. The connector 11 is then inserted into the opening, and the baffle 12 is precisely sealed over the opening. Preferably, foam 5 is also attached to the front edge of the baffle 12. The foam 5 fills the tiny gap between the baffle 12 and the motor housing, further enhancing the sealing effect and preventing dust, moisture, and other foreign objects from entering.

[0029] Example 2, see Figure 5 and Figure 6 This embodiment provides a molded wire harness connector, which is basically the same in structure as Embodiment 1, except that a barb 133 is provided on the outer wall of the socket portion 13. The barb 133 can be embedded in the injection-molded block 4 to form a mechanical locking structure, which fits tightly and prevents the injection-molded block 4 from coming off the socket portion 13 during use, thereby enhancing the structural stability of the connector and ensuring that the injection-molded block 4 reliably protects the socket hole 132 for a long time. For ease of operation, a recess 42 can be provided on the surface of the injection-molded block 4, which is more conducive to finger gripping and makes operation more convenient.

[0030] A wire-separating protrusion 134 is provided on the tail end face of the socket 13. The wire-separating protrusion 134 can separate and guide the multiple connecting wires 3 extending from the socket hole 132, making the connecting wires 3 more neatly arranged, which is convenient for subsequent wiring and organization. It also plays a certain limiting role for the connecting wires 3, making the connecting wires 3 more stable when bending and fixing, while avoiding the connecting wires from tangling and interfering with each other, thus improving wiring efficiency and reliability.

[0031] A positioning groove 123 is recessed at the edge of the baffle 12 to achieve rapid and accurate positioning of the wire harness connector, improve installation efficiency, and ensure accurate connector installation position.

Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
