Description

Technical Field

[0001] This application relates to the technical field of wire harnesses, and in particular to a terminal block for multi-interface wire harnesses. Background Technology

[0002] Refrigerators, as indispensable appliances in modern households, play a vital role in people's daily lives. With the continuous development of refrigerator technology, their functions have become increasingly diversified, and their internal electronic components and circuits have become more complex. To achieve these various functions, refrigerators are equipped with multiple wiring harnesses. These harnesses undertake important tasks such as transmitting power and signals, playing a crucial role in the normal operation of the refrigerator. The diversification and intelligent development of refrigerator functions have led to a continuous increase in the number and types of internal wiring harnesses, making the effective management of these harnesses a significant issue.

[0003] In refrigerator wiring harness management, the traditional approach is to organize wiring harnesses for different functions using separate interfaces. In this method, each function's wiring harness corresponds to one interface, and as the refrigerator's functions increase, the number of interfaces also increases. Different function wiring harnesses, such as refrigeration system wiring harnesses, lighting system wiring harnesses, and control system wiring harnesses, all have their own independent interfaces. These interfaces are scattered throughout the refrigerator's interior, lacking unified planning and centralized management.

[0004] The numerous and scattered interfaces result in a chaotic wiring harness layout inside the refrigerator, hindering centralized management. During the refrigerator's production, installation, and maintenance, staff must spend considerable time and effort locating and connecting each interface, increasing operational complexity and difficulty. Furthermore, the scattered interfaces easily lead to tangled wiring harnesses, increasing the risk of harness damage and consequently affecting the refrigerator's normal operation. Therefore, further improvements are needed. Utility Model Content

[0005] To address the above issues, this application provides a terminal block for multi-interface wire harnesses.

[0006] This application provides a terminal block for multi-interface wire harnesses, which adopts the following technical solution: A terminal block for a multi-interface wire harness includes a first housing and a second housing fastened to the first housing. The inner surface of the second housing is arched away from the first housing to form a mounting base. The side wall of the mounting base is provided with mounting grooves for the interface to be inserted. Several mounting grooves are spaced apart along the length of the mounting base. A semi-circular plate is provided in the middle of both the first housing and the second housing. When the first housing and the second housing are closed, the two semi-circular plates surround to form an outlet tube for the wire harness to pass through.

[0007] By adopting the above technical solution, the terminal block is configured with a structure including a first housing and a second housing that snap together, facilitating the assembly and disassembly of the terminal block. The inner surface of the second housing is arched to form a mounting base, and the side wall of the mounting base has multiple mounting slots spaced along the length direction, which can be used to embed interfaces. This allows for the centralized installation and organization of multiple interfaces with different functions, facilitating the centralized management of multiple wire harnesses inside the refrigerator. The semi-circular plates in the middle of the first and second housings, when closed, enclose a wire outlet tube, providing a passage for the wire harnesses to pass through, allowing the wire harnesses to exit the terminal block in an orderly manner.

[0008] Preferably, the inner surface of the first housing is provided with an annular first baffle, and a first groove is formed between the first baffle and the inner peripheral wall of the first housing. The second housing is provided with a second baffle that is adapted to the first groove. When the first housing and the second housing are fastened together, the first baffle is embedded in the first groove, and a sealing strip is embedded in the first groove.

[0009] By adopting the above technical solution, when the first housing and the second housing are fastened together, the first baffle is embedded in the first groove, and a sealing strip is embedded in the first groove. This structural design can enhance the sealing of the fastening point of the first housing and the second housing, effectively reduce the entry of dust, moisture and other substances into the terminal block, thereby protecting the interfaces and wire harnesses inside the terminal block, improving the waterproof and dustproof performance and stability of the terminal block, and facilitating centralized management of multi-interface wire harnesses inside the terminal block.

[0010] Preferably, the outer walls of the opposite sides of the second housing are provided with at least one pair of elastic limiting buckles, and the outer walls of the opposite sides of the first housing are provided with limiting grooves corresponding to the positions of the limiting buckles. The outer surface of the limiting buckle is a guiding slope, and its cross-section gradually increases along the fastening direction.

[0011] By adopting the above technical solution, the elastic limiting buckles set on the outer walls of the second housing on opposite sides correspond to the limiting slots opened on the outer walls of the first housing on opposite sides. The outer surface of the limiting buckle is a guide slope, and the cross-section gradually increases along the fastening direction. In this way, when the first housing and the second housing are fastened together, the limiting buckle can smoothly engage with the limiting slot by means of the guide slope, realizing the fastening of the first housing and the second housing quickly and accurately. At the same time, the elastic limiting buckle can ensure the stability of the fastening, reduce the easy separation of the two, and improve the convenience of the wiring terminal assembly and the reliability of the use.

[0012] Preferably, the inner surface of the semicircular plate is provided with arc-shaped protrusions, and the arc-shaped protrusions on the two semicircular plates are staggered.

[0013] By adopting the above technical solution, an arc-shaped protrusion is set on the inner surface of the semi-circular plate and the arc-shaped protrusions on the two semi-circular plates are staggered. After the cable outlet tube is formed, the contact between the cable harness and the inner surface of the cable outlet tube becomes more complex and tortuous, which increases the friction between the cable harness and the cable outlet tube. This improves the stability of the cable harness in the cable outlet tube, reduces the shaking and displacement of the cable harness during use, and also plays a certain protective role, reducing the damage to the cable harness from external collisions and friction.

[0014] Preferably, the inner surface of the semi-circular plate is provided with at least one arc-shaped groove, and the arc-shaped grooves on the two semi-circular plates form an annular groove, and a sealing gasket is embedded in the arc-shaped groove.

[0015] By adopting the above technical solution, an arc-shaped groove is opened on the inner surface of the semi-circular plate. The arc-shaped grooves of the two semi-circular plates form an annular groove and are fitted with a sealing gasket, which can enhance the sealing performance at the outlet pipe, effectively reduce the entry of dust, moisture and other impurities into the terminal block from the gap between the outlet pipe and the wire harness, and improve the stability and reliability of the terminal block in use.

[0016] Preferably, the outer wall of the first housing is provided with a third baffle on both sides of the semi-circular plate, and a second groove is formed between the third baffle and the semi-circular plate. The outer wall of the second housing is provided with a fourth baffle that matches the second groove. The fourth baffle is fitted into the second groove, and a sealing strip is also embedded in the second groove.

[0017] By adopting the above technical solution, a suitable fourth baffle is provided on the outer wall of the second housing and is fitted into the second groove, and a sealing strip is embedded in the second groove, which can enhance the sealing performance of the terminal block and protect the internal interface and wiring harness.

[0018] Preferably, the outer surface of the outlet tube is provided with external threads, the outlet tube is fitted with a limiting ring, the inner wall of the limiting ring is provided with internal threads, and the internal threads are threadedly connected to the external threads.

[0019] By adopting the above technical solution, the outer surface of the outlet pipe is provided with external threads, and a limiting ring with internal threads is fitted on the outer sleeve. This facilitates centralized management of multiple different functional interfaces inside the refrigerator, and the threaded connection between the limiting ring and the outlet pipe can play a certain limiting role for the wire harness.

[0020] Preferably, the inner side of the end of the limiting ring away from the first housing and the second housing is provided with a pushing slope, and the outer surface of the outlet tube is provided with a pushing member that cooperates with the pushing slope. As the limiting ring is tightened, the pushing member is driven to press against the wire harness.

[0021] By adopting the above technical solution, a pushing slope is provided on the inner side of the end of the limiting ring near the first and second housings, and a pushing component that cooperates with the pushing slope is provided on the outer surface of the outlet tube. The pushing component can be driven to press against the wire harness by tightening the limiting ring, which facilitates centralized management of the interfaces of multiple wire harnesses in the refrigerator and makes the wire harness more secure.

[0022] In summary, this application has the following beneficial effects: 1. By setting up terminal blocks, multiple interfaces are centrally located in the mounting slot of the mounting base, which facilitates centralized management of multiple wiring harnesses inside the refrigerator and solves the problem of scattered interfaces and messy wiring harness layout in the traditional method; 2. When the first and second housings are closed, the two semi-circular plates enclose each other to form a wire outlet tube, providing a passage for the wire harness to pass through, so that the wire harness is arranged in an orderly manner and the risk of the wire harnesses getting tangled together is reduced; 3. The installation of terminal blocks reduces the time and effort required for staff to find and connect various interfaces during refrigerator production, installation, and maintenance, thus reducing the complexity and difficulty of operation.

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0026] This application discloses a terminal block for a multi-interface wire harness.

[0027] Example 1: A terminal block for a multi-interface wire harness, as shown in the reference. Figure 1 , Figure 2 The system includes a first housing 1 and a second housing 2 fastened to the first housing 1. In this embodiment, a connecting strip 3 is fixedly connected between the first housing 1 and the second housing 2. Two connecting strips 3 are spaced apart along the length of the first housing 1. The middle part of the connecting strip 3 can be bent so that the first housing 1 is rotatably connected to the second housing 2 through the connecting strip 3. The second housing 2 is fastened to the first housing 1, and the two cooperate to form a closed space, providing protection for the internal interfaces and wiring harnesses, avoiding the influence of the external environment, and also facilitating centralized management of multiple interfaces. It should be noted that both the first housing 1 and the second housing 2 can be made of plastic.

[0028] Specifically, for the engagement between the first housing 1 and the second housing 2, at least one pair of elastic limiting buckles 21 are provided on the opposite outer walls of the second housing 2, and limiting grooves 11 corresponding to the positions of the limiting buckles 21 are provided through the opposite outer walls of the first housing 1. The outer surface of the limiting buckles 21 is a guiding slope, and its cross-section gradually increases along the engagement direction. This design allows the limiting buckles 21 to slide smoothly into the limiting grooves 11 when the first housing 1 and the second housing 2 are engaged, and after engagement, the limiting buckles 21 can be firmly locked in the limiting grooves 11, reducing the risk of accidental separation of the first housing 1 and the second housing 2. The elastic limiting buckles 21 can be made of plastic, utilizing their elastic deformation to achieve the engagement and separation functions, or they can be integrally formed with the second housing 2.

[0029] Furthermore, to improve the sealing effect, an annular first baffle 12 is protruding from the inner surface of the first housing 1, forming a first groove 13 between the first baffle 12 and the inner peripheral wall of the first housing 1. The second housing 2 has a second baffle 22 protruding from it, which matches the first groove 13. When the first housing 1 and the second housing 2 are fastened together, the first baffle 12 is engaged within the first groove 13. Further, a sealing strip 4 is embedded within the first groove 13. The sealing strip 4 can be made of rubber, possessing good elasticity and sealing performance. The second housing 2 has a second baffle 22 protruding from it, which matches the first groove 13. When the first housing 1 and the second housing 2 are fastened together, the second baffle 22 is engaged within the first groove 13, simultaneously compressing the sealing strip 4, thereby achieving a good sealing effect, reducing the entry of dust, moisture, etc., into the terminal block, and protecting the interface and wiring harness from damage. The structure after fastening can be referred to... Figure 3 .

[0030] The inner surface of the second housing 2 arches away from the first housing 1 to form a mounting base 5. The side wall of the mounting base 5 is provided with a mounting groove 51 for the interface to be inserted. Several mounting grooves 51 are spaced apart along the length of the mounting base 5. The shape of the several interfaces can be set according to the interface shape.

[0031] Reference Figure 4 The first housing 1 and the second housing 2 each have a semi-circular plate 6 at their center. When the first housing 1 and the second housing 2 are closed, the two semi-circular plates 6 enclose each other to form an outlet tube 61 through which the wire harness passes. At least one arc-shaped protrusion 62 protrudes from the inner surface of each semi-circular plate 6, and the arc-shaped protrusions 62 on the two semi-circular plates 6 are staggered. At least one arc-shaped groove 63 is formed on the inner surface of each semi-circular plate 6, and the arc-shaped grooves 63 on the two semi-circular plates 6 form an annular groove. A sealing gasket 64 is embedded within the arc-shaped groove 63.

[0032] Back Figure 1 , Figure 2 The outer wall of the first housing 1 is provided with a third baffle 14 on both sides of the semi-circular plate 6. A second groove 15 is formed between the third baffle 14 and the semi-circular plate 6. The outer wall of the second housing 2 is provided with a fourth baffle 23 that is adapted to the second groove 15. The fourth baffle 23 is embedded in the second groove 15. A sealing strip 4 is also embedded in the second groove 15.

[0033] Furthermore, the outer peripheral wall of the second housing 2 is provided with a mounting plate 24 so that the terminal block can be installed in the main compartment of the refrigerator by adhesive.

[0034] The implementation principle of the multi-interface wire harness terminal block in this application embodiment is as follows: This multi-interface wire harness terminal block, through the snap-fit ​​structure of the first housing 1 and the second housing 2, centrally installs multiple interfaces within the mounting groove 51 of the mounting base 5, achieving centralized management of the multi-interface wire harness inside the refrigerator. Simultaneously, by setting various sealing structures, such as the sealing strip 4 in the first groove 13 and the second groove 15, and the sealing gasket 64 at the outlet pipe 61, the entry of dust and moisture into the terminal block is effectively reduced, protecting the interfaces and the wire harness.

[0035] The cooperation between the limiting buckle 21 and the limiting slot 11, along with the fixing effect of the limiting ring 7 on the wire harness, increases the connection stability and reliability of the terminal block. Compared with the traditional decentralized interface management method, this terminal block greatly improves the problem of messy internal wire harness layout in the refrigerator, facilitates centralized management, reduces the difficulty of refrigerator production, installation and maintenance, reduces the risk of wire harness damage, and improves the overall performance and stability of the refrigerator.

[0036] Example 2: Reference Figure 5 , Figure 6 The difference from Embodiment 1 is that the outer surface of the outlet tube 61 is provided with an external thread 65, the outlet tube 61 is fitted with a limiting ring 7, the inner wall of the limiting ring 7 is provided with an internal thread 71, and the internal thread 71 is threadedly connected to the external thread 65.

[0037] Reference Figure 7 The inner side of the end of the limiting ring 7 away from the first housing 1 and the second housing 2 is provided with a pushing slope 72. The outer surface of the cable outlet tube 61 is provided with a pushing member 66 that cooperates with the pushing slope 72. In this embodiment, the pushing member 66 specifically includes two arc-shaped strips that are respectively fixedly connected to the end faces of the two semi-circular plates 6. The axis of the arc-shaped strips is located between the two arc-shaped strips. As the limiting ring 7 is tightened, the arc-shaped strips are driven to move towards the direction of the wire harness, and then press against the wire harness.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
