[0025] like Figure 1 , Figure 2 As shown, the cable joint protection device includes a housing assembly 100 and a clamp 200.

[0026] Combination Figure 1 and Figure 3 The housing assembly 100 includes a first housing 110 and a second housing 120. It is understood that the first housing 110 may be one half of the housing assembly 100, and the second housing 120 is the other half. The first housing 110 and the second housing 120 are connected to form the housing assembly 100, which is used to fit over the cable connector 20. The first housing 110 and the second housing 120 may be made of aluminum-magnesium alloy or 304 stainless steel, providing excellent fire and explosion resistance.

[0027] Specifically, the first housing 110 is provided with a first pair of interfaces, and the second housing 120 is provided with a second pair of interfaces. When the first housing 110 and the second housing 120 are connected, the first pair of interfaces and the second pair of interfaces are arranged opposite to each other.

[0028] More specifically, the first pair of interfaces is located on the lower side of the first housing 110, and the second pair of interfaces is located on the upper side of the second housing 120, with the first housing 110 and the second housing 120 docking one above the other.

[0032] Combination Figure 1 , Figure 2 and Figure 3 The clamp 200 is used to connect the first housing 110 and the second housing 120 together.

[0033] Specifically, there are two sets of clamps 200. One set of clamps 200 is used to clamp a pair of oppositely arranged first connecting parts 111 and second connecting parts 121, and the other set of clamps 200 is used to clamp another pair of oppositely arranged first connecting parts 111 and second connecting parts 121. It can be understood that the pair of oppositely arranged first connecting parts 111 and second connecting parts 121 are connected by one set of clamps 200, and the other pair of oppositely arranged first connecting parts 111 and second connecting parts 121 are connected by the other set of clamps 200. Furthermore, the clamps 200 allow the first connecting parts 111 and second connecting parts 121 to fit more tightly, thereby improving the sealing performance.

[0034] It should be noted that each set of clamps 200 includes multiple clamps 200, and the multiple clamps 200 in each set are spaced apart along the length direction of the housing assembly 100. In this way, for any pair of oppositely arranged first connecting parts 111 and second connecting parts 121, the sealing between the first connecting parts 111 and the second connecting parts 121 can be improved under the joint clamping of the multiple clamps 200.

[0035] Combination Figure 2 , Figure 6 and Figure 7Furthermore, the clamp 200 includes a support frame 210, a first clamping member 220, a second clamping member 230, a first elastic member 240, and a second elastic member 250. The first clamping member 220 is movably disposed within the support frame 210, and the second clamping member 230 is movably disposed within the support frame 210 and disposed opposite to the first clamping member 220. The first elastic member 240 abuts against the side of the first clamping member 220 away from the second clamping member 230, and the second elastic member 250 abuts against the side of the second clamping member 230 away from the first clamping member 220. The first clamping member 220 abuts against the side of the first connecting portion 111 away from the second connecting portion 121, and the second clamping member 230 abuts against the side of the second connecting portion 121 away from the first connecting portion 111.

[0036] Specifically, the support frame 210 includes a first support portion 211, a second support portion 212 spaced apart from the first support portion 211, and a third support portion 213 connected at both ends to the first support portion 211 and the second support portion 212, respectively. One end of a first elastic member 240 is connected to the first support portion 211. A first clamping member 220 is located between the first support portion 211 and the second support portion 212 and connected to the other end of the first elastic member 240. One end of a second elastic member 250 is connected to the second support portion 212. A second clamping member 230 is located between the first support portion 211 and the second support portion 212 and connected to the other end of the second elastic member 250, with the second clamping member 230 located on the side of the first clamping member 220 closer to the second support portion 212. The first elastic member 240 and the second elastic member 250 can be springs.

[0037] Understandably, the first elastic member 240 connects the first clamping member 220 to the support frame 210, and the deformation direction of the first elastic member 240 is parallel to the spacing direction between the first clamping member 220 and the second clamping member 230. Similarly, the second elastic member 250 connects the second clamping member 230 to the support frame 210, and the deformation direction of the second elastic member 250 is parallel to the spacing direction between the first clamping member 220 and the second clamping member 230. Under the action of the first elastic member 240, the first clamping member 220 abuts against the side of the first connecting portion 111 away from the second connecting portion 121. Under the action of the second elastic member 250, the second clamping member 230 abuts against the side of the second connecting portion 121 away from the first connecting portion 111. Thus, under the action of the clamp 200, the first connecting portion 111 and the second connecting portion 121 can be connected, and the sealing between the first connecting portion 111 and the second connecting portion 121 can be guaranteed.

[0038] This utility model's cable joint protection device uses clamps 200 to fix the first housing 110 and the second housing 120, eliminating the need for bolt holes on the first connecting portion 111 and the second connecting portion 121. Bolts are used to connect the first housing 110 and the second housing 120. Furthermore, by adjusting the specific position (distance between adjacent clamps 200) and the number of clamps 200, effective sealing between the first connecting portion 111 and the second connecting portion 121 can be achieved. If poor sealing is found in certain areas during subsequent testing, additional clamps 200 can be added to further improve the sealing between the first connecting portion 111 and the second connecting portion 121. Additionally, the first clamping member 220 and the second clamping member 230 make surface contact with the first connecting portion 111 and the second connecting portion 121, respectively, resulting in a larger contact area and further improving the sealing between the first connecting portion 111 and the second connecting portion 121.
