Description

An adapter with a sealed and waterproof function Technical Field

[0001] This utility model relates to the field of adapters, and more particularly to an adapter with a sealing and waterproof effect. Background Technology

[0002] An adapter is an interface device or software used to connect different devices, systems, or components. Its core function is to solve compatibility issues between them, enabling objects that cannot work together directly to interact smoothly.

[0003] In electronic device connectivity and adaptation scenarios, the adapter, as a key component for signal or power transmission between different devices, directly affects the stability and reliability of the system. Especially in special scenarios such as outdoor operations, humid environments, or industrial production, the adapter must have good sealing and waterproof capabilities to prevent moisture intrusion and damage to internal electronic components, while also ensuring effective heat dissipation to avoid heat buildup affecting the normal operation of the equipment.

[0004] Currently available adapters have some shortcomings: traditional adapters mostly use a simple shell splicing method, and when the output and input ends of the wiring harness pass through the adapter, there is no sealing structure for the insertion hole. After long-term use, moisture can enter the shell due to gaps between the shell and the wiring harness. Therefore, an adapter with a sealing and waterproof effect is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides an adapter with a sealing and waterproof effect, which aims to improve the existing technology where the output and input ends of the wire harness do not have a sealing structure inside the insertion hole. After long-term use, gaps may appear, leading to water leakage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adapter with a sealing and waterproof effect, comprising a housing, mounting feet fixedly connected to all four sides of the housing, heat dissipation channels provided on both the front and rear sides of the housing, a buckle fixedly connected to the top surface of the housing, a top cover plate snapped onto the surface of the buckle, wire through holes provided at both the front and rear ends of the housing, and a sealing clamping mechanism provided at both the front and rear ends of the housing.

[0007] The sealing clamping mechanism includes a rubber ring, the surface of which contacts a threaded seat, and a connecting seat is fixedly connected to the surface of the threaded seat.

[0008] As a further description of the above technical solution:

[0009] The connecting seat is rotatably connected to a rotating block at the end away from the threaded seat, a threaded rod is rotatably connected to the inner wall of the connecting seat, a threaded block is slidably connected to the inner side wall of the connecting seat, a connecting rod is fixedly connected to the surface of the threaded block, a clamping block a is fixedly connected to the end of the connecting rod away from the threaded block, and a clamping block b is fixedly connected to the surface of the connecting seat.

[0010] As a further description of the above technical solution:

[0011] The bottom end of the outer wall of the upper cover plate is in contact with the top end of the shell.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the rubber ring is in contact with the inner side wall of the thread hole.

[0014] As a further description of the above technical solution:

[0015] The inner side of the thread hole is provided with an internal thread groove, and the outer arc surface of the thread seat is provided with an external thread groove. The outer wall of the thread seat is threadedly connected to the inner wall of the thread hole.

[0016] As a further description of the above technical solution:

[0017] Both the rubber ring and the threaded seat have cavities at their centers.

[0018] As a further description of the above technical solution:

[0019] The threaded block has an internal thread groove at its center, and the threaded block is threadedly connected to the surface of the threaded rod.

[0020] As a further description of the above technical solution:

[0021] The rotating block is fixedly connected to the rotation center axis of the threaded rod.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the top cover plate adopts a double fixing method of buckle and bolt to form a tight top waterproof barrier; the sealing clamping mechanism at the wire hole uses the elastic deformation of the nitrile rubber ring to wrap the wire harness, and cooperates with the threaded seat to squeeze and seal, preventing moisture from entering from the gaps in the wire harness.

[0024] 2. In this utility model, the clamping block structure effectively protects the wire harness. Rotating the rotating block causes clamping block a and clamping block b to come closer together, which can firmly clamp the wire harness, disperse the pulling force, avoid wire harness breakage, and ensure the stability of signal or power transmission.

[0031] 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.

[0032] Referring to Figures 1-3, one embodiment of this utility model is provided: an adapter with a sealed and waterproof effect, including a housing 1. Mounting feet 2 are fixedly connected to all four sides of the housing 1. Four sets of mounting feet 2 are provided, which, together with bolts, can be used to fix the entire unit to a mounting device or other location. Heat dissipation channels 4 are provided on both the front and rear sides of the housing 1. The heat dissipation channels 4 are inclined and located at the front and rear ends of the housing 1, effectively dissipating the temperature generated by the internal electronic components during operation. A buckle 6 is fixedly connected to the top surface of the housing 1. A top cover plate 3 is snapped onto the surface of the buckle 6. The bottom end of the outer wall of the top cover plate 3 contacts the top of the housing 1. During installation, the top cover plate 3 can be snapped onto the surface of the housing 1 by the deformation of the buckle 6, and bolts can be used to connect and fix the top cover plate 3 to the side of the housing 1. Wire holes 7 are provided at both the front and rear ends of the housing 1. The wires of the internal output and input terminals can be passed through the wire holes 7. Sealing clamping mechanisms 5 are provided at both the front and rear ends of the housing 1.

[0033] Referring to Figures 3 and 4, the sealing clamping mechanism 5 includes a rubber ring 51. The outer wall of the rubber ring 51 contacts the inner side wall of the wire hole 7. The rubber ring 51 is made of nitrile rubber. A threaded seat 52 contacts the surface of the rubber ring 51. A cavity is opened at the center of both the rubber ring 51 and the threaded seat 52. By opening a cavity at the center of the rubber ring 51 and the threaded seat 52, the internal wire harness can be passed through the cavity. An internal thread groove is opened on the inner side of the wire hole 7. An external thread groove is opened on the outer arc surface of the threaded seat 52. The outer wall of the threaded seat 52 is threadedly connected to the inner wall of the wire hole 7. By threading the threaded seat 52 to the inner wall of the wire hole 7, the rubber ring 51 can be compressed to deform it, and its inner diameter can wrap around the output and input wires, thereby ensuring the overall sealing effect and preventing water on the wire harness from entering the interior of the housing 1 through the gaps. A connecting seat 53 is fixedly connected to the surface of the threaded seat 52.

[0034] Referring to Figures 3 and 4, a rotating block 55 is rotatably connected to the end of the connecting seat 53 away from the threaded seat 52. The rotating block 55 is fixedly connected to the rotation center axis of the threaded rod 54. When the connecting seat 53 rotates, it will drive the threaded rod 54 to rotate synchronously, and the threaded block 56 will move threadedly on the surface of the threaded rod 54. The threaded rod 54 is rotatably connected to the inner wall of the connecting seat 53, and the threaded block 56 is slidably connected to the inner side wall of the connecting seat 53. An internal thread groove is opened at the center of the threaded block 56. The threaded block 56 is threadedly connected to the surface of the threaded rod 54. A connecting rod 57 is fixedly connected to the surface of the threaded block 56. A clamping block a58 is fixedly connected to the end of the connecting rod 57 away from the threaded block 56. When the threaded block 56 moves, it will drive the connecting rod 57 and the clamping block a58 to move synchronously to approach the clamping block b59, thereby pressing the output and input lines to prevent the wire harness from being pulled and breaking. The clamping block b59 is fixedly connected to the surface of the connecting seat 53.

[0035] Working principle: When the adapter is working, the internal electronic components will generate heat. The heat dissipation channels 4, which are inclined on the front and back sides of the housing 1, play a role. The inclined design allows air to form natural convection in the channel. Hot air rises and is discharged, while cold air flows in from below, achieving effective dissipation of internal heat. At the same time, the inclined structure can also prevent external water droplets from directly entering the housing 1.

[0036] When installing the top cover 3, the elastic deformation of the buckle 6 is used to snap the top cover 3 onto the top of the housing 1. At this time, the bottom of the outer wall of the top cover 3 is in contact with the top of the housing 1. Then, the top cover 3 is connected and fixed to the side of the housing 1 by bolts. The double fixing method makes the top cover 3 and the housing 1 tightly connected, forming a waterproof barrier on the top of the adapter to prevent water droplets from entering.

[0037] When it is necessary to connect the wire harness, first pass the output and input wire harnesses through the wire holes 7 at both ends of the housing 1. At this time, the wire harness will pass through the cavity between the rubber ring 51 and the center of the threaded seat 52 in the sealing clamping mechanism 5. Then, rotate the connecting seat 53 to drive the threaded seat 52 to rotate. Since the external thread groove on the outer arc surface of the threaded seat 52 and the internal thread groove on the inner side of the wire hole 7 cooperate with each other, the threaded seat 52 will squeeze the rubber ring 51 during the process of screwing into the wire hole 7. The rubber ring 51 is made of nitrile rubber, which has good elasticity and sealing performance. After being squeezed, it deforms and its inner diameter shrinks, tightly wrapping the wire harness that has passed through. At the same time, the outer wall of the rubber ring 51 is tightly attached to the inner side wall of the wire hole 7, preventing water from entering the housing 1 from the gap between the wire harness and the wire hole 7, thus achieving a sealed and waterproof effect.

[0038] To prevent the wire harness from breaking due to tension, a rotating block 55 is rotatable. The rotating block 55 is fixedly connected to the rotation center axis of the threaded rod 54. Therefore, when the rotating block 55 rotates, it drives the connecting seat 53 and the threaded rod 54 to rotate synchronously. During the rotation of the threaded rod 54, the threaded block 56, which is threadedly connected to it, moves along the axial direction of the threaded rod 54 under the guidance of the inner side wall of the connecting seat 53. The threaded block 56 drives the clamping block a58 to move through the connecting rod 57, so that it moves closer to the clamping block b59 fixed on the surface of the connecting seat 53, thereby forming a clamping force on the wire harness, dispersing the tensile force on the wire harness, and preventing the wire harness from breaking due to excessive force at the connection point with the adapter.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
