[0002] A wire harness connector is a component used in electronic devices and electrical systems to connect wires or cables, enabling the transmission of signals and electricity.

[0003] When two wire harnesses that need to be connected are mated through a connector, the male and female terminals are inserted into each other and make close contact. In this process, current can be conducted from the wires of one wire harness to the wires of the other wire harness through the terminals, realizing power transmission. For signal transmission, the electrical signal is also transmitted from one end to the other through good contact between the terminals.

[0004] Terminals are a core component of wire harness connectors. In existing technologies, terminals are usually encapsulated within the connector housing, and the wire cores of the wire harness are soldered and fixed to the terminals within the housing. During use, if the wire harness is accidentally pulled, it can easily become loose from the terminals, leading to poor contact and affecting the normal use of the wire harness connector.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-4 The present invention provides the following technical solution: a wire harness connector, including a housing 1 and terminals 2 encapsulated in the housing 1, and further including: a protective sleeve 3, fasteners 4 and rubber rings 5.

[0034] Furthermore, by Figure 1 and Figure 3As shown, in this embodiment, the protective sleeve 3 is detachably installed at the tail end of the outer casing 1. The wire harness passes through the protective sleeve 3 and is welded and fixed to the terminal 2. The fastener 4 is used to fasten the protective sleeve 3 and the wire harness, and the wire harness passes through the fastener 4. The rubber ring 5 is fixed inside the protective sleeve 3, and the inner wall of the rubber ring 5 is tightly fitted to the outer wall of the wire harness. With the above solution, when in use, the wire harness passes through the protective sleeve 3 and is welded and fixed to the terminal 2, and the terminal 2 is encapsulated inside the outer casing 1. At this time, the inner wall of the rubber ring 5 is tightly fitted to the outer wall of the wire harness. The protective sleeve 3 further protects the wire harness, and the rubber ring 5 improves the stability of the wire harness, preventing the wire harness from accidentally detaching from the terminal 2, thus improving the safety and service life. The fastener 4 further reinforces the protective sleeve 3 and the wire harness, further improving the tightness of the wire harness connection.

[0035] It should be noted that in this utility model, the protective sleeve 3 is an integrally molded injection part, which provides a reliable protective barrier for the internal cable. Structurally, in order to avoid cable wear, the inner wall of the protective sleeve 3 is designed to be a smooth surface to reduce the coefficient of friction. It relies on the flexibility of the rubber ring 5 to constrain the cable. In addition, the corners of the end face of the protective sleeve 3 are rounded to avoid cutting the cable.

[0036] Optionally, by Figure 1 and Figure 2 As shown in this embodiment, the fastener 4 includes an arc-shaped half-hoop 41 and a locking bolt 42. The two arc-shaped half-hoops 41 are symmetrically distributed. Two symmetrically distributed side wings 31 are fixed on the protective sleeve 3, and the side wings 31 are located inside the two arc-shaped half-hoops 41. The locking bolt 42 is installed on the arc-shaped half-hoops 41 by thread engagement, and the locking bolt 42 passes through the side wings 31. With the above solution, in use, the two arc-shaped half-hoops 41 are joined together to form a ring and sleeved on the cable. At the same time, the two arc-shaped half-hoops 41 clamp the side wings 31. After tightening the locking bolt 42, the two arc-shaped half-hoops 41 clamp the side wings 31 and the cable, further reinforcing the protective sleeve 3 and the wire harness, and further improving the tightness of the wire harness connection.

[0037] It should be noted that in this utility model, the arc-shaped semi-hoop 41 is an integrally molded injection part. Structurally, the corners of the end face of the arc-shaped semi-hoop 41 are rounded to avoid cutting the cable.

[0038] Preferably, by Figure 1 and Figure 2As shown in this embodiment, a through hole 411 for the locking bolt 42 to pass through is machined at one end of the arc-shaped semi-hoop 41, and a threaded hole 412 for the locking bolt 42 to be screwed into is machined at the other end. With the above solution, the locking bolts 42 at both ends of the arc-shaped semi-hoop 41 have opposite installation directions during use. Since the locking bolts 42 are installed in opposite directions, when subjected to external vibration, impact or tension, the two locking bolts 42 can restrain each other, reducing the risk of loosening due to force in one direction, thereby better maintaining the tightness, ensuring that the cable can maintain a stable connection under various complex working conditions, extending its service life, and reducing the potential for failure caused by loose connection.

[0039] Preferably, by Figure 1 and Figure 2 As shown, this embodiment also includes a rubber liner 43, which is bonded and fixed to the inner wall of the arc-shaped semi-hoop 41. Multiple equally spaced anti-slip protrusions 431 are fixed to the inner wall of the rubber liner 43. With the above solution, the rubber liner 43 is flexible and has anti-slip protrusions 431 during use. The rubber liner 43 clamps the cable, allowing it to closely fit the outer surface of the cable. When the cable is subjected to slight external pulling or vibration, the rubber liner 43 can deform appropriately due to its good flexibility, effectively buffering these external forces and preventing damage such as outer sheath wear and internal core wire breakage caused by excessive force.

[0040] On the other hand, the presence of the anti-slip protrusions 431 further enhances the clamping effect of the rubber liner 43 on the cable, greatly increasing the friction between the rubber liner 43 and the cable, preventing the cable from easily slipping or shifting, thereby ensuring the stability and safety of the cable, guaranteeing the continuity and reliability of electrical signal and power transmission, and laying a solid foundation for the normal operation of the entire electrical system.

[0041] Preferably, by Figure 1 and Figure 3 As shown in this embodiment, the protective sleeve 3 has an internal thread and an external thread at the tail end of the outer shell 1. The protective sleeve 3 is installed at the tail end of the outer shell 1 by thread engagement, which is convenient and stable, and also facilitates the disassembly of the protective sleeve 3 during maintenance.

[0042] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, it also includes: anti-slip protrusions 32, and multiple anti-slip protrusions 32 are fixed at equal intervals along the circumferential direction on the outer wall of the protective sleeve 3. After adopting the above solution, when in use, the anti-slip protrusions 32 make it easier for the staff to turn the protective sleeve 3.

[0043] Preferably, by Figure 1 and Figure 3 As shown in this embodiment, a groove 33 is machined on the inner wall of the protective sleeve 3, and the rubber ring 5 is snapped into the groove 33. The outer wall of the rubber ring 5 is tightly fitted to the inner wall of the groove 33, which makes installation convenient and provides high stability. It also makes it easy to disassemble and replace the damaged rubber ring 5.

[0044] Preferably, by Figure 1 and Figure 4 As shown, this embodiment also includes: elastic sheet 6, multiple elastic sheets 6 are fixed at equal intervals along the circumferential direction to the outer wall of the head end of the outer shell 1, and a locking block 61 is fixed at the end of the elastic sheet 6 away from the outer shell 1. With the above solution, when the two terminals 2 are connected, the locking block 61 can clamp the outer shell 1 of the other connector under the elastic force of the elastic sheet 6, further improving the stability of the two terminals 2 after connection and avoiding accidental loosening.

[0045] It should be noted that the terminal 2 of this utility model is an exemplary description based on the female terminal. In actual use, it needs to be used in conjunction with the male terminal. The outer shell 1 of the male terminal has the same structural shape as the outer shell 1 in this utility model. After docking, the elastic pieces 6 on the two outer shells 1 are misaligned and formed a mutual clamping state by the locking block 61.

[0046] Components not described in detail in this article are existing technologies.

[0047] The working principle and usage process of this utility model: When using the wire harness connector of this utility model, the wire harness passes through the protective sleeve 3 and is welded and fixed to the terminal 2, and the terminal 2 is encapsulated in the outer shell 1. At this time, the inner wall of the rubber ring 5 is tightly fitted with the outer wall of the wire harness. The protective sleeve 3 further protects the wire harness, and the rubber ring 5 is used to improve the stability of the wire harness, prevent the wire harness from accidentally detaching from the terminal 2, and improve the safety and service life of use.

[0048] In addition, during use, the two arc-shaped semi-hoops 41 are joined together to form a ring and fitted onto the cable. At the same time, the two arc-shaped semi-hoops 41 clamp the side wing 31. After tightening the locking bolt 42, the two arc-shaped semi-hoops 41 clamp the side wing 31 and the cable, further reinforcing the protective sleeve 3 and the wire harness, and further improving the tightness of the wire harness connection.

[0049] In another aspect of this invention, when the two terminals 2 are mated, the locking block 61 can clamp the outer shell 1 of the other connector under the elastic force of the elastic piece 6, further improving the stability of the two terminals 2 after mating and avoiding accidental loosening.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
