Abstract
Description
Technical Field
[0001] This utility model relates to the field of protective device technology, specifically a protective device for automotive wiring harness connectors. Background Technology
[0002] Automotive wiring harness connectors are key components of automotive electrical systems, responsible for connecting electrical equipment and transmitting power and signals. Their stability and reliability are crucial to the overall performance and safety of the vehicle. Automotive wiring harness connector protection devices are specifically designed to protect these connectors, resisting external damage, ensuring stable performance, extending service life, and guaranteeing the normal operation of the automotive electrical system.
[0003] Existing automotive wiring harness connector protection devices mostly use snap-fit connections for fixing. However, since vehicles inevitably experience vibrations and bumps during driving, the snap-fit connections are not very secure and are prone to loosening, thus affecting the protective effect. Therefore, a new automotive wiring harness connector protection device is proposed to improve the above-mentioned problems. Utility Model Content
[0004] The purpose of this utility model is to provide a protective device for automotive wiring harness connectors. By setting up a connecting component, it solves the problem that existing automotive wiring harness connector protective devices mostly use a snap-fit connection method for fixing. Since vehicles inevitably experience vibration and bumps during driving, the snap-fit connection is not very secure and is prone to loosening, thus affecting the protective effect.
[0005] This utility model is achieved through the following technical solution:
[0006] This utility model is a protective device for an automotive wiring harness connector, including a first protective shell, a second protective shell, and a connecting assembly for fixing the first and second protective shells. The connecting assembly includes a horizontal plate, a support plate, and a threaded rod. The horizontal plate has a through hole, and the support plate has a limiting groove and a retaining groove. The horizontal plate cooperates with the limiting groove. A retaining plate is installed at one end of the threaded rod. The retaining plate cooperates with the through hole. After rotating 90°, the retaining plate abuts against the horizontal plate. A limiting plate is threadedly engaged on the threaded rod. The bottom of the limiting plate abuts against the surfaces of the horizontal plate and the support plate.
[0007] Furthermore, the horizontal plate is installed on the second protective shell, the support plate is installed on the first protective shell, the limiting groove and the slot are connected, and the card plate and the slot cooperate.
[0008] Furthermore, a circular plate is installed at the other end of the threaded rod.
[0009] Furthermore, the limiting plate has a threaded hole, and the threaded rod passes through the threaded hole and engages with the threaded part of the limiting plate.
[0010] Furthermore, a first arc-shaped hole is provided on the first protective shell, and a second arc-shaped hole is provided on the second protective shell, with the first arc-shaped hole and the second arc-shaped hole cooperating.
[0011] This utility model has the following beneficial effects:
[0012] This invention, through the setting of a connecting component, first places the horizontal plate against the limiting groove, then drives the clamping plate through the through hole via a threaded rod. After rotating the clamping plate 90°, it comes into contact with the horizontal plate. Then, the limiting plate moves downward along the threaded rod until it contacts the surfaces of the horizontal plate and the support plate. This solves the problem that existing automotive wiring harness connector protection devices mostly use a snap-fit connection method. Since vehicles inevitably experience vibrations and bumps during driving, the snap-fit connection is not very secure and is prone to loosening, thus affecting the protective effect.
[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] 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.
[0021] Please see Figure 1-5 This utility model provides a technical solution: a protective device for automotive wiring harness connectors, including a first protective shell 1, and a second protective shell 2 installed on the first protective shell 1 via a hinge. The first protective shell 1 and the second protective shell 2 can provide a physical barrier for the automotive wiring harness connector, preventing it from being subjected to mechanical damage such as collision, squeezing, and friction, and avoiding damage to the connector or loosening of the connection due to external forces, thereby ensuring the stability of the electrical connection.
[0022] When it is necessary to protect the automotive wiring harness connector, first place the automotive wiring harness connector inside the first protective shell 1. The first protective shell 1 has a first arc-shaped hole 101, and the second protective shell 2 has a second arc-shaped hole 201. With the first arc-shaped hole 101 and the second arc-shaped hole 201 in sync, place the wiring harness between the first arc-shaped hole 101 and the second arc-shaped hole 201, and then rotate the first protective shell 1 and the second protective shell 2 to the closed state using a hinge.
[0023] When it is necessary to fix the first protective shell 1 and the second protective shell 2, the horizontal plate 301 is installed on the second protective shell 2 by bolts, and the support plate 303 is installed on the first protective shell 1 by bolts. The connecting assembly 3 is used to fix the first protective shell 1 and the second protective shell 2. The connecting assembly 3 includes the horizontal plate 301, the support plate 303 and the threaded rod 306. The support plate 303 has a limiting groove 304 and a locking groove 305. The limiting groove 304 and the locking groove 305 are connected. When the horizontal plate 301 cooperates with the limiting groove 304, the second protective shell 2 drives the horizontal plate 301 to move, so that the horizontal plate 301 abuts against the limiting groove 304, achieving a preliminary positioning effect.
[0024] A through hole 302 is provided on the horizontal plate 301. A clamping plate 307 is installed on one end of the threaded rod 306 by welding. The clamping plate 307 cooperates with the through hole 302 and the clamping plate 307 cooperates with the clamping groove 305. The operator drives the clamping plate 307 to align with the through hole 302 and insert it through the threaded rod 306. After the clamping plate 307 passes through the through hole 302 and enters the clamping groove 305, the threaded rod 306 is rotated 90°, so that the threaded rod 306 drives the clamping plate 307 to rotate 90° and then abut against the bottom of the horizontal plate 301.
[0025] A limiting plate 308 is threadedly engaged on the threaded rod 306. The limiting plate 308 has a threaded hole 310. With the threaded rod 306 passing through the threaded hole 310 and threadedly engaged with the limiting plate 308, the limiting plate 308 is rotated, causing the limiting plate 308 to move downwards along the threaded rod 306 until the bottom of the limiting plate 308 simultaneously contacts the surfaces of the horizontal plate 301 and the support plate 303. This tightly fixes the first protective shell 1 and the second protective shell 2 together, preventing the protective shells from loosening or separating due to vibration, bumps, or other reasons during vehicle operation, thus effectively protecting the wire harness connector.
[0026] With a circular plate 309 fixedly installed at the other end of the threaded rod 306, the circular plate 309 can prevent the limiting plate 308 from coming off.
