Broadly speaking, it also encompasses the application of electricity as a power source and energy source in various fields. It also encompasses power transmission and transformation projects. Cable joints, also known as cable heads, are commonly referred to as cable connectors. After a cable is laid, the individual segments must be connected to form a continuous line. These connection points are called cable joints. The cable joints in the middle of a cable line are called intermediate joints, while the ones at each end are called terminal heads. Cable joints are used to secure incoming and outgoing cables, providing protection against water, dust, and vibration.

[0003] The prior art patent authorization number is CN 202121285 U, a cable joint protection device. This utility model provides fully sealed waterproof protection for the cable. At the same time, due to the high strength and flame retardancy of the shell itself, and the high-strength solid material filled in the shell, it can protect the joints in the cable from water, explosion, fire, and external force damage.

[0004] Problems with existing technologies:

[0005] When the above device is installed in actual application, it needs to be connected and fixed by multiple screws, which makes the installation complicated. Secondly, there is a risk of the shell falling when it is installed at a high place. Utility Model Content

[0026] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0027] like Figure 1 As shown, a power engineering cable joint protection device includes two housings 1 and multiple card frame plates 3 and multiple fixing frames 4 respectively arranged on the two housings 1. The two housings 1 are symmetrically arranged above and below and each has an expansion portion 1a and two symmetrical contraction portions 1b. The upper expansion portion 1a and the two contraction portions 1b are connected to three embedded card plates 2 and three card frame plates 3.

[0028] Two fixing frames 4 are fixed on the lower side expansion portion 1a and the two contraction portions 1b;

[0029] The three embedded card plates 2 are set to a right-angled Z shape and are adapted to the three fixed frames 4 on the rear side. The three card frame plates 3 are all set to an L shape and have multiple first grooves 31 fixed on the side. The three card frame plates 3 are respectively adapted to the three fixed frames 4 on the front side, so that when the upper shell 1 and the lower shell 1 are close to each other, the upper shell 1 drives the card frame plate 3 and the three fixed frames 4 on the front side to be squeezed and inserted, so that the first grooves 31 on the card frame plate 3 and the fixed frame 4 are squeezed and dislocated and slide down, so that the two shells 1 are fitted together and merged together. Then he uses pliers or other tools to pinch the fixed frame 4 and the card frame plate 3, thereby increasing the sliding length of the card frame plate 3 and the fixed frame 4, and improving the connection tightness. Then he pinches the corresponding fixed frame 4 and the card frame plate 3 of the contraction part 1b, thereby driving the internal pressure plate 6 in the contraction part 1b to fully squeeze and contact with the cable, thereby improving the sealing effect.

[0030] Refer to the attached Figure 2 Two buckle plates 9 are fixed in the lower shell body 1 on the left and right sides of the outward expansion part 1a, and inner pressure plates 6 are fixed in the four contraction parts 1b. The four inner pressure plates 6 are all provided with open wire grooves to facilitate the connection and positioning of the cables.

[0031] Furthermore, four retaining plates 7 are fixedly provided in the lower outwardly expanded portion 1 a . The four retaining plates 7 are all in an n-shape and have a plurality of retaining holes. The four retaining plates 7 are divided into two groups and are respectively adapted to the two retaining rings 5 ​​.

[0032] Furthermore, the two retaining rings 5 ​​are both set to a semicircular shape, and second grooves 51 are fixed at both ends of the two retaining rings 5. Each second groove 51 is adapted to the card hole, so that when the second groove 51 is squeezed and inserted into the card hole plate 7, the second groove 51 can form an embedded card connection state with the card hole, thereby braking the retaining ring 5.

[0033] According to the above structure, the cable connector is first placed in the outer expansion portion 1a on the lower side, and the two sections of the cable of the connector are located in the latch plate 9 and the inner pressure plate 6 on the lower side. Then, the second grooves 51 on the retaining ring 5 are pressed and engaged with the two corresponding card hole plates 7 in the front and rear, so that the second grooves 51 are inserted and squeezed and dislocated and slide through the multiple card holes on the card hole plates 7. In this way, the retaining ring 5 can slide down to press and fix the cable on the lower side of the shell 1.

[0034] Refer to the attached Figure 3 , both of the two buckle plates 9 are provided with open wire grooves, and the two buckle plates 9 are respectively adapted to the two lower pressure rings 8. The two lower pressure rings 8 are both set to a semicircular shape, and both ends of the two lower pressure rings 8 are fixed with linkage plates 81.

[0035] Furthermore, two slide rail columns 82 are fixedly provided on each linkage plate 81 , and the upper ends of the two slide rail columns 82 are sleeved in the fixing block 83 , and the fixing block 83 is fixed inside the upper shell 1 .

[0036] Furthermore, two springs 84 are fixed on the opposite sides of the fixed block 83 and the linkage plate 81. The two springs 84 are respectively mounted on the two slide rail columns 82, so that the springs 84 can always push the lower pressure ring 8 away from the fixed block 83. In this way, when the upper shell 1 is flipped and merged with the lower shell 1, the lower pressure ring 8 can be brought into contact with the cable in advance for squeezing, thereby achieving the effect of pre-positioning and clamping, and avoiding the misalignment of the cables affecting the merging adjustment of the two shells 1.

[0037] The working principle of the present invention is as follows: first, place the cable connector in the outer expansion portion 1a on the lower side, and make the two cable sections of the connector located in the buckle plate 9 and the inner pressure plate 6 on the lower side, then press and clamp the second grooved teeth 51 on the retaining ring 5 into the two corresponding card hole plates 7 at the front and rear, so that the second grooved teeth 51 are inserted and squeezed and dislocated in the multiple card holes on the card hole plates 7 to slide through, so that the retaining ring 5 can slide down to press and fix the cable on the lower shell 1, then the three embedded card plates 2 on the upper shell 1 are respectively embedded and adjusted to form a locking state, and then the upper shell 1 is turned over and fitted close to the lower shell 1, so that the lower pressure ring 8 is first contacted and clamped with the cable, and then as the upper shell 1 continues to turn over, the spring 84 is squeezed, which can increase the clamping force of the lower pressure ring 8 on the cable;

[0038] At the same time, as the upper shell 1 approaches the lower shell 1, the upper shell 1 drives the card frame plate 3 to be squeezed and clamped with the three fixed frames 4 on the front side, so that the first groove tooth 31 on the card frame plate 3 and the fixed frame 4 are squeezed and dislocated to slide down, so that the two shells 1 fit together and merge together. Then he uses pliers or other tools to pinch the fixed frame 4 and the card frame plate 3, so as to increase the sliding length of the card frame plate 3 and the fixed frame 4, and improve the connection tightness. Then he pinches the corresponding fixed frame 4 and card frame plate 3 of the contraction part 1b, so as to drive the internal pressure plate 6 in the contraction part 1b to fully squeeze and contact with the cable, thereby improving the sealing effect.

[0039] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
