Embodiment

[0026] An explosion-proof electrical connector that can be quickly assembled, including a connector body 1. Pre-pressure components 2 are embeddedly installed at the top and bottom of the connector body 1. Fixed frames 3 are fixedly connected to both sides of the connector body 1. A movable arm 4 is movably installed inside the fixed frame 3. A clamping hoop 5 located outside the fixed frame 3 is fixedly connected to one side of the movable arm 4. Clamping strips 6 are fixedly connected to the inner wall of the clamping hoop 5 at equal intervals. A fixing plate 11 is fixedly connected to one side of the fixed frame 3. A fixing pin 7 is penetrated through the top of the fixing plate 11. One end of the fixing pin 7 penetrates into the inside of the movable arm 4. A first spring 8 is sleeved on the surface of the fixing pin 7. The two ends of the first spring 8 are respectively fixedly connected to the fixing plate 11 and the fixing pin 7. A fastening bolt 9 is penetrated through the top of the pre-pressure component 2.

[0027] The specific usage process is as follows: First, pull the fixed bolt 7 upward so that the end of the fixed bolt 7 moves out of the inside of the movable arm 4. Then, expand the clamp 5 and the movable arm 4 together to the outside. Since the clamp 5 is fixed on the movable arm 4, during specific operation, just move the clamp 5 to the outside. Then, insert the end of the wire harness into the joint body 1. After that, push the movable arm 4 and the clamp 5 back to their original positions. During this process, the movable arm 4 will enter the fixing bracket 3. Among them, the movable arm 4 will first push the fixed bolt 7 upward, and at the same time, the fixed bolt 7 will also stretch the first spring 8. After the movable arm 4 is completely inserted into the fixing bracket 3, under the action of the first spring 8, the fixed bolt 7 is pulled back, and the end of the fixed bolt 7 is inserted into the jack 15 on the movable arm 4 to fix the movable arm 4. At this time, the two clamps 5 are also combined together and are sleeved on the wire harness, and the two clamps 5 also clamp the wire harness tightly, thus completing the fixing of the wire harness and finishing the installation of the wire harness. Therefore, compared with the traditional method of first sleeving the joint body 1 on the wire harness and then pressing it on the machine, many steps are simplified, which is convenient for the user's operation, saves a lot of time, improves the user's work efficiency, speeds up the production progress, and provides convenience for the user's work use. Among them, after the two clamps 5 are combined, the card strip 6 will also tightly press on the surface of the wire harness to prevent the wire harness from sliding. In order to further prevent the joint from loosening, a fastening bolt 9 can also be inserted for further fixation. During operation, insert the fastening bolt 9 into the reserved installation hole two 24 on the pre-pressure plate 21 and press it down, and then rotate the fastening bolt 9 to fix it on the joint body 1. During this process, under the tightening and extrusion of the fastening bolt 9, the pre-pressure plate 21 will move downward in the movable slot 12, and at the same time, it will also compress the second spring 22. When the pre-pressure plate 21 moves downward, it will also drive the pre-pressure part 23 to slide in the corresponding limit hole 14. After that, the pre-pressure part 23 passes through the limit hole 14 and enters the joint body 1 to press the wire harness tightly, thus realizing the further fixation of the wire harness and improving the firmness of the assembly of the wire harness and the joint, providing convenience for the user's use. Among them, the entire pre-pressure assembly 2 is also used to pre-press and position the installed wire harness. After the wire harness is inserted into the joint body 1, the wire harness will push the pre-pressure part 23 upward and stretch the second spring 22 at the same time. Then, under the action of the second spring 22, the pre-pressure plate 21 will be pulled downward, and then the pre-pressure plate 21 will pull the pre-pressure part 23 downward. In this way, the pre-pressure part 23 will pass through the corresponding limit hole 14 and clamp on the wire harness to realize the pre-pressing and positioning of the wire harness, preventing the wire harness from moving randomly and providing assistance for the subsequent installation work of the user. Among them, the movable slot 12 is used for the pre-pressure plate 21 to move during work and plays a role in limiting the sliding of the pre-pressure plate 21 to prevent the pre-pressure assembly 2 from falling, providing convenience for the user's work use. The limit hole 14 is used for the pre-pressure part 23 to slide and work, and the reserved installation hole one 13 is used for installing the fastening bolt 9. The additional end 10 is used to extend the length of the joint body 1 to meet the adaptation with different types of equipment, and at the same time, it can also bundle the wire ends exploded at the end of the joint body 1 together.Thus, it provides convenience for the user's assembly work. The inner diameter of the joint body 1 is the same as that of the added end 10, so that when the joint body 1 and the added end 10 are butt - assembled, a complete channel can be formed, ensuring that the wire harness can smoothly and quickly extend through during installation, avoiding being blocked in the added end 10, and providing convenience for the user's work. The inner diameter of the clamp 5 is the same as that of the joint body 1, enabling the wire harness to be clamped more tightly during installation, ensuring that the wire harness is more secure, and providing convenience for the user's work.

Then the pre - pressing plate 21 will pull the pre - pressing members 23 downwards. In this way, the pre - pressing members 23 will pass through the corresponding limiting holes 14 and clamp on the wire harness, realizing the pre - pressing and positioning of the wire harness, preventing the wire harness from moving randomly, and providing assistance for the subsequent installation work of the user.
