Description

Technical Field

[0001] This invention relates to the field of protective bushings, specifically a conductor protective bushing. Background Technology

[0002] Based on the actual design requirements and technological development of electronic products, modular design is required within electronic products. Signal and electrical signal transmission between modules must be carried out through wires. The wires need to pass through the module shell or the metal plate separating the modules. Corresponding wire vias need to be reserved on the metal plate or module shell. If the wires pass directly through the holes in the metal plate, long-term contact and friction between the wires and the wire vias will greatly lead to wire wear or breakage, ultimately causing damage to the electronic products. Therefore, a wire protective bushing is proposed. Summary of the Invention

[0003] The purpose of this invention is to provide a conductor protective bushing to solve the problem mentioned in the background art, which is that long-term contact and friction between the conductor and the conductor through hole will lead to conductor wear or breakage.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A wire protection bushing is installed in a wire through-hole reserved in the housing of an electronic module to protect the wire. It includes a bushing body with a wire hole. The bushing body is composed of an integrally connected outer protective plate, a connecting plate, and an inner protective plate. The outer protective plate is tightly attached to the outer wall of the electronic module housing, and the inner protective plate is located on the inner wall of the electronic module housing cavity. The vertical height of the connecting plate does not exceed the vertical height of the outer protective plate. The vertical height of the outer protective plate exceeds the vertical height of the wire through-hole cavity, and the lateral length of the outer protective plate exceeds the lateral length of the wire through-hole cavity. The top surfaces of the outer and inner protective plates are on the same plane, and the vertical height of the inner protective plate does not exceed the vertical height of the outer protective plate. A groove is formed between the inner and outer protective plates to confine the bushing body within the wire through-hole.

[0005] Furthermore, the top surface of the connecting plate is lower than the top surface of the inner protective plate, and the outer side wall of the connecting plate is in close contact with the hole wall of the wire through hole.

[0006] Furthermore, the outer protective plate, the connecting plate, and the inner protective plate all have a rectangular shape in side view, and the side surface area of ​​the outer protective plate exceeds that of the connecting plate.

[0007] Furthermore, the lateral length of the outer protective plate is equal to the lateral length of the inner protective plate.

[0008] The beneficial effects of the present invention are as follows: The bushing body formed by the outer protective plate, the connecting plate and the inner protective plate can be directly embedded in the wire through hole and allow the wire to pass through the wire hole, so that the wire can contact the bushing body. This avoids the wire from being worn or broken when the wire passes directly through the wire through hole, thereby protecting the wire and improving the reliability of the electronic module and the wire.

[0011] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0012] Please see Figure 1-4 This invention provides a technical solution: a wire protection bushing, installed in a wire through-hole 3 reserved in the electronic module housing 1 to protect the wires. It includes a bushing body 2 with a wire hole 25. The bushing body 2 is composed of an outer protective plate 21, a connecting plate 22, and an inner protective plate 23 integrally connected. The outer protective plate 21 is in close contact with the outer wall of the electronic module housing 1, the inner protective plate 22 is located on the inner wall of the electronic module housing 1, and the vertical height of the connecting plate 22 does not exceed that of the outer protective plate 21. The vertical height of the outer sheath 21 exceeds the vertical height of the wire through hole 3 cavity. The horizontal length of the outer sheath 21 exceeds the horizontal length of the wire through hole 3 cavity. The top surfaces of the outer sheath 21 and the inner sheath 23 are on the same plane. The vertical height of the inner sheath 23 does not exceed the vertical height of the outer sheath 21. A groove 24 is formed between the inner sheath 23 and the outer sheath 21. The groove 24 is used to confine the bushing body 2 within the wire through hole 3.

[0013] It should be noted that the outer protective plate 21, the connecting plate 22, and the inner protective plate 23 all have a rectangular shape when viewed from the side. The side surface area of ​​the outer protective plate 21 is greater than that of the connecting plate 22. The lateral length of the outer protective plate 21 is equal to that of the inner protective plate 23. The top surface of the connecting plate 22 is lower than the top surface of the inner protective plate 23. The outer side wall of the connecting plate 22 is closely attached to the wall of the wire through hole 3. The top of the wall of the wire through hole 3 is attached to the bottom surface of the groove 24. The outer side wall of the connecting plate 22 is closely attached to the wall of the wire through hole 3 so that the bushing body 1 can be embedded in the wire through hole 3. Example

[0014] Combination Figure 1 As shown, a wire protection bushing has a main body 2 composed of an outer protective plate 21, a connecting plate 22, and an inner protective plate 23 integrally connected. The bottom surface of the connecting plate 22 and the bottom surface of the inner protective plate 23 are on the same plane. The vertical height of the connecting plate 22 does not exceed the vertical height of the inner protective plate 23, the horizontal length of the connecting plate 22 does not exceed the horizontal length of the inner protective plate 23, and the vertical height of the inner protective plate 23 does not exceed the vertical height of the outer protective plate 21. This allows the main body 2 of the bushing to be installed in a wire through-hole 3. The bottoms of the connecting plate 22 and the inner protective plate 23 are attached to the bottom surface of the hole wall of the wire through-hole 3. Based on the dimensions of the outer protective plate 21, the inner protective plate 23, and the connecting plate 22, the main body 2 of the bushing can be quickly installed in the wire through-hole 3 reserved in the electronic module housing 1, improving the ease of use of the wire protection bushing. Example

[0015] Combination Figure 2 As shown, a wire protection bushing has a main body 2 composed of an outer protective plate 21, a connecting plate 22, and an inner protective plate 23 integrally connected. In this case, the bottom surfaces of the outer protective plate 21 and the connecting plate 22 are on the same plane, and the vertical height of the inner protective plate 23 does not exceed the vertical height of the outer protective plate 21. This allows the main body 2 of the bushing to be quickly embedded into the wire through hole 3, and the bottom of the connecting plate 22 is attached to the bottom surface of the hole wall of the wire through hole 3. Based on the dimensions of the outer protective plate 21, the inner protective plate 23, and the connecting plate 22, the main body 2 of the bushing can be quickly installed in the wire through hole 3 reserved in the electronic module housing 1, which improves the ease of use of the wire protection bushing.

[0016] Usage Examples Combination Figure 3 and Figure 4As shown, the wire protection bushing has the following usage examples: the wire through hole 3 is opened on the electronic module housing 1, and then according to the structure of the bushing body 2 in Embodiment 1 or Embodiment 2, the bushing body 2 is embedded in the wire through hole 3, and the wire of the electronic module passes through the wire hole 25. This can prevent contact wear with the edge of the electronic module housing 1 under long-term vibration and transportation, thereby preventing the wire from being damaged and playing a protective role for the wire.

[0017] In summary, by using the bushing body 2, the wire through hole 3 can be directly embedded and the wire can pass through the wire hole 25, so that the wire can contact the bushing body 1. This avoids the wire from being worn or broken when the wire passes directly through the wire through hole 3, thus protecting the wire and improving the reliability of the electronic module and the wire.

[0018] This wire protection bushing is designed with different shapes and sizes of plastic protective bushings, taking into account the lead-out positions and methods of different wires between the modules and the wire size. Ultimately, it protects the connecting wires between the internal cavities of the product from damage, so as to achieve the purpose of protecting the lead-out wires.
