Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a quick-installation new energy cable. Background Technology

[0002] To simplify the installation process of new energy cables, improve connection efficiency, and ensure reliable power transmission under various environmental conditions, existing quick-installation new energy cables typically use standardized plug-in connectors, i.e., plug-and-lock connectors, to quickly complete electrical connections.

[0003] For example, Chinese patent application number CN 202420311573.5 discloses a quick-installation new energy cable. Its technical solution includes a first cable and a second cable. One end of the first cable is equipped with a plug, and one end of the second cable is equipped with a connector. One end of the plug is inserted into the connector and engages with it. A sleeve presses and positions a locking component, ensuring that the locking component can lock and fix the internal connector, allowing the plug and connector to be firmly connected as one unit. Compared to the traditional method where the plug is directly threaded onto the connector, this solves the problem of wear on the electrode plates at the end of the internal connector when the plug rotates, effectively reducing the probability of cable connector damage. However, using a sleeve to press and position the locking component can lead to loosening under external vibration or force. Loosening results in an unstable connection, failing to effectively reduce the probability of cable connector damage. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a quick-installation new energy cable to solve the technical problem that the existing technology uses a sleeve to press and position the locking part, which may loosen under the action of top vibration or external force.

[0005] To achieve the above objectives, this utility model provides a quick-installation new energy cable, comprising a first cable and a second cable. A plug is fixedly installed at the end of the first cable, and a connector is fixedly installed at the end of the second cable. The plug and connector have an alternating concave-convex structure at their ends, and are electrically connected. The quick-installation new energy cable further includes:

[0006] An external protective sleeve is fitted onto the second cable. One end of the external protective sleeve facing away from the first cable abuts against the back of the connector. A threaded groove is formed on the inner surface of the external protective sleeve near the end of the first cable.

[0007] A locking cover is sleeved on the first cable, and one end of the locking cover facing away from the second cable abuts against the back of the plug. The inside of the locking cover is provided with a threaded connection section, which is threadedly connected to the threaded groove.

[0008] A sealing part used to block the port of the locking cover.

[0009] Furthermore, the sealing part includes:

[0010] Guide strips, there are several guide strips, and the several guide strips are evenly distributed circumferentially on the outer protective cylinder;

[0011] A sealing ring is slidably disposed on the guide strip, and the outer edge of the sealing ring cooperates with the inner wall of the port of the locking cover.

[0012] Furthermore, a sealing ring is provided at the junction of the locking cover and the first cable.

[0013] Furthermore, an arc-shaped limiting section is provided on one end of the external protective cylinder near the first cable, and the threaded groove is provided on the inner surface of the arc-shaped limiting section.

[0014] Furthermore, the inner wall of the locking cover is provided with a damping anti-rotation ring, which cooperates with the arc-shaped limiting section.

[0015] Furthermore, the plug has a guide rod in the middle, and the connector has a groove in the middle, with the guide rod inserted into the groove.

[0016] Furthermore, both the external protective cylinder and the locking cover have raised sections at their ends.

[0017] Furthermore, both the plug and the connector have deep holes on their backs. The connection between the end of the first cable and the plug is located in the deep hole, and the connection between the end of the second cable and the connector is also located in the deep hole.

[0018] The beneficial effects of this utility model are as follows: When using the quick-installation new energy cable of this utility model, the plug with the first cable and the connector with the second cable are aligned and plugged in. Then, at the contact area between the plug and the connector, the external protective cylinder and the locking cover are connected. The axial initial locking achieved by the threaded groove and the threaded connection section, and the further anti-rotation locking effect achieved by the cooperation of the damping anti-rotation and the arc surface limit section arc surface root, can avoid loosening caused by vibration or external force.

[0032] The first aspect of this utility model proposes a quick-installation new energy cable, such as... Figure 1-8 As shown, the cable includes a first cable 1 and a second cable 2. A plug 3 is fixedly installed at the end of the first cable 1, and a connector 4 is fixedly installed at the end of the second cable 2. The ends of the plug 3 and connector 4 have an alternating concave-convex structure for interlocking, and they are electrically connected. The quick-installation new energy cable also includes:

[0033] An external protective sleeve 5 is fitted onto the second cable 2. One end of the external protective sleeve 5 facing away from the first cable 1 abuts against the back of the connector 4. A threaded groove is provided on the inner surface of the external protective sleeve 5 near the first cable 1.

[0034] Locking cover 6 is sleeved on the first cable 1. The end of the locking cover 6 facing away from the second cable 2 abuts against the back of the plug 3. The inside of the locking cover 6 is provided with a threaded connection section 7, which is threadedly connected to the threaded groove.

[0035] A sealing part used to block the port of the locking cover 6.

[0036] In this embodiment, the sealing part includes:

[0037] Guide strip 8, there are several guide strips 8, and several guide strips 8 are evenly distributed around the outer protective cylinder 5;

[0038] The sealing ring 9 is slidably mounted on the guide strip 8, and the outer edge of the sealing ring 9 cooperates with the inner wall of the port of the locking cover 6.

[0039] In this embodiment, a sealing ring 10 is provided at the junction of the locking cover 6 and the first cable 1.

[0040] In this embodiment, an arc-shaped limiting section 11 is provided on one end of the external protective cylinder 5 near the first cable 1, and a threaded groove is provided on the inner surface of the arc-shaped limiting section 11.

[0041] In this embodiment, a damping anti-rotation ring 12 is provided on the inner wall of the locking cover 6, and the damping anti-rotation ring 12 cooperates with the arc-shaped limiting section 11.

[0042] Working process and principle: In this embodiment, the plug 3 with the first cable 1 and the connector 4 with the second cable 2 are connected to each other through a concave-convex alignment. Then, at the contact area between the plug 3 and the connector 4, the external protective cylinder 5 and the locking cover 6 are connected. Specifically, the external protective cylinder 5 is manually rotated, and the threaded groove on the external protective cylinder 5 near the end of the first cable 1 is threadedly connected to the threaded connection section 7 inside the locking cover 6, thus completing the initial axial locking of the first cable 1 and the second cable 2. After the threaded connection section 7 is completely rotated into the threaded groove, the damping anti-rotation ring 12 inside the locking cover 6 is placed at the root of the arc surface of the arc surface limiting section 11 on the external protective cylinder 5, thus completing a further anti-rotation locking effect.
