Description

Technical Field

[0001] The utility model belongs to the technical field related to safe electricity use, and more specifically, particularly relates to a waterproof connector for outdoor safe electricity use. Background Art

[0002] The earliest wires consisted of metal conductors wrapped in insulating materials to prevent current leakage or short circuits. With the advancement of industrialization and the development of science and technology, wires have gradually become one of the indispensable infrastructures of modern society. With the acceleration of industrialization and urbanization, the demand for electricity continues to grow. As the main tool for power transmission, wires play a vital role in the power system. However, the existing wire joints are easily exposed to the sun for a long time due to the tape. This situation can easily cause the tape to fall off or cause it to be loose, and the wires are in a humid environment for a long time. In this environment, moisture may penetrate into the wire joints, causing the insulation material to become damp, the conductivity to increase, and even cause short circuits, fires and other safety hazards.

[0003] Therefore, in view of this, the existing structure and defects are studied and improved, and a waterproof connector for outdoor electrical safety wires is provided, in order to achieve a more practical purpose. Utility Model Content

[0004] The utility model provides a waterproof connector for outdoor electrical safety wires, which is used to overcome the above-mentioned defects in the prior art.

[0005] The purpose and effect of the utility model of a waterproof connector for outdoor electrical safety wires are achieved by the following specific technical means:

[0006] A waterproof connector for outdoor electrical safety wires, comprising: a first shell, a third thread is provided at the left front end of the first shell, a second shell is threadedly connected to the surface of the third thread, and a fourth thread is provided at the right front end of the second shell; a rubber pad is fixedly provided on the inner side of the left front end of the first shell, a first protective shell is fixedly installed on the inner side of the rubber pad, a first thread is provided at the left front end of the first protective shell, a second protective shell is rotatably connected to the surface of the first thread, and a second thread is provided at the front end of the second protective shell.

[0010] According to a further technical solution, clamping rubber hoops are symmetrically provided at both ends of the first shell and the second shell, and a fifth thread is provided on the lower surface of the clamping rubber hoops.

[0011] According to a further technical solution, a rubber sleeve is connected to the surface of the clamping rubber hoop symmetrically arranged at both ends, and a sixth thread is arranged on the inner side of the rubber sleeve, and the sixth thread is threadedly connected with the fifth thread.

[0012] According to a further technical solution, the third thread provided at the left front end of the first shell and the fourth thread provided at the right front end of the second shell form a threaded connection.

[0013] According to a further technical solution, a first thread provided at the front end of the left side of the first protective shell is threadedly connected with a second thread provided at the front surface of the left side of the second protective shell.

[0014] According to a further technical solution, a threading through hole is provided on the inner side of the rubber sleeve, and the threading through hole is at the same horizontal position as the through hole and the thread end placement cavity.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] By symmetrically arranging clamping rubber hoops at both ends of the first shell and the second shell with good sealing performance, it is possible to effectively prevent liquids such as water and moisture from penetrating into the interior of the connector, protect the wires and connecting parts, ensure the normal operation of the electrical equipment, and also play a role in shock absorption and noise reduction, protecting the wires from damage caused by external vibration or impact. The rubber shell rotatably connected at the outer end can completely wrap the connector to form a sealed waterproof layer, effectively preventing water, moisture and other liquids from penetrating into the interior of the connector, thereby improving the waterproof performance of the connector and ensuring the reliability and safety of the wire connection.

[0017] The first shell and the second shell are connected by threads and have an olive-shaped shape. This design can provide a more stable and reliable joint for the wires, ensure the tight connection of the wire connections, and prevent them from loosening or falling off, thereby effectively preventing the joints from malfunctioning due to external shock or vibration. The threaded connection can effectively prevent external substances such as water, moisture, and dust from entering the interior of the joint, thereby improving the waterproof and dustproof performance and extending the service life of the joint and electrical equipment. The olive-shaped shell design can effectively improve the waterproof performance, and the streamlined shape can effectively reduce the possibility of water staying on the surface of the shell and reduce the risk of water penetrating into the interior of the joint, thereby protecting the wire connection components from water damage.

[0018] By providing the first protective shell and the second protective shell inside the first shell and the second shell, they can serve as additional sealed spaces, provide double waterproof protection, effectively isolate external water, moisture and other liquids to prevent them from penetrating into the connector, and further ensure the safe operation of the wire connection components. This design can also avoid leakage or short circuit caused by water vapor intrusion, protect electrical equipment and wiring from damage, and improve the stability and reliability of the electrical system. The first protective shell and the second protective shell are usually made of wear-resistant and pressure-resistant materials, which can effectively resist external pressure and impact, enhance the durability of the connector, and extend its service life.
