First cable sealing ring 26 and second cable sealing ring 27 equally play the role of sealing, and described first Cable sealing ring 26 prevents rainwater between first cable 9 and the first cable fixing end 12 and first cable Enter the fixed channel 41 of first cable between 9 and the third cable fixing end 22；Second cable sealing ring 27 is anti- Only rainwater is between second cable 10 and the second cable fixing end 13 and second cable 10 and the described 4th Enter the fixed channel 51 of second cable between cable fixing end 23.

First cable sealing ring 26 and second cable sealing ring 27 can be any suitable sealing ring, at this In one specific embodiment of utility model, first cable sealing ring 26 and second cable sealing ring 27 are that rubber is close Seal.

First cable sealing ring 26, which is located in the fixed channel 41 of first cable, can be located at first cable Any suitable position in fixed channel 41, second cable sealing ring 27 is located at can in the fixed channel 51 of second cable To be located at any suitable position in the fixed channel 51 of second cable, shown in referring to Figure 1~Fig. 2, in the utility model A specific embodiment in, first cable sealing ring 26 be located at the fixed channel 41 of first cable far from the protection The end of box body 3, second cable sealing ring 27 are located at the separate protection box body 3 in the fixed channel 51 of second cable End.

The side of first cartridge body 11 is connected with the side of second cartridge body 21, is also possible to two Separation unit, the side of second the cartridge body 21 preferably, side of first cartridge body 11 is rotatably connected.Please Shown in Figure 2, in a specific embodiment of the utility model, the cable lug protective device further includes hinge 8, institute The side for the first cartridge body 11 stated connects the side of second cartridge body 21 by the hinge 8.

In order to further protect cable lug, shown in referring to Figure 1~Fig. 2, in a specific implementation of the utility model In example, the diameter of the cable connection head protection chamber 31 is greater than the diameter and second electricity in the fixed channel 41 of first cable The diameter in the fixed channel 51 of cable.

In use, the insulating layer at the both ends for needing the first cable 9 and the second cable 10 that connect is removed, exposes and lead Then the exposed conducting wire at both ends is wound, winding position, that is, cable connection location is then placed in the second box body master by line In body 21, the first cable 9 is placed in third cable fixing end 22, the second cable 10 is placed in the 4th cable fixing end 23, Then the first box body 1 lid being located on the second box body 2, then the first cartridge body 11 lid is located in the second cartridge body 21, thus Cable connection head protection chamber 31 is formed between the first cartridge body 11 and the second cartridge body 21, winding position connects positioned at cable The end of a thread is protected in chamber 31, and the first cable fixing end 12 lid is located in third cable fixing end 22 in the first cable fixing end 12 The fixed channel 41 of the first cable is formed between third cable fixing end 22, the first cable 9 is located at the fixed channel 41 of the first cable In, the second cable fixing end 13 lid is located in the 4th cable fixing end 23 to solid in the second cable fixing end 13 and the 4th cable The fixed channel 51 of the second cable is formed between fixed end 23, the second cable 10 is located in the fixed channel 51 of the second cable, then passes through the One fixing piece 6 connects the first cable fixing end 12 and third cable fixing end 22, and it is solid to connect the second cable by the second fixing piece 7 Fixed end 13 and the 4th cable fixing end 23, it is last as shown in Figure 3.

Due to having the cartridge body gasket between first cartridge body 11 and second cartridge body 21 14, there is the first fixed end bodies gasket between the first cable fixing end 12 and the third cable fixing end 22 15, there is the second fixed end bodies gasket between the second cable fixing end 13 and the 4th cable fixing end 23 16, therefore the first cable fixing end 12 and third cable fixing end 22 are being connected by the first fixing piece 6 and consolidated by second Determine part 7 and connects the second cable fixing end 13 and when the 4th cable fixing end 23, it can be to the cartridge body gasket 14, described the One fixed end bodies gasket 15 and the second fixed end bodies gasket 16 generate pressure, achieve the effect that sealing with this.

Similar, since the fixed channel 41 of first cable has first cable sealing ring 26, second electricity The fixed channel 51 of cable has second cable sealing ring 27, therefore is connecting the first cable fixing end by the first fixing piece 6 12 and third cable fixing end 22 and the second cable fixing end 13 and the 4th cable fixing end 23 are connected by the second fixing piece 7 When, pressure can be generated to first cable sealing ring 26 and second cable sealing ring 27, sealing is achieved the effect that with this.

Due to being relatively large in diameter for the cable connection head protection chamber 31, cable connection location is placed in the cable connection It is vacant state when in head protection chamber 31, to prevent the laggard water of the utility model seals damaged from impregnating, utmostly protects cable The safety of link position.

And the design of the utility model can resist certain shock, squeeze.

Therefore, the utility model is used, so that cable lug, that is, cable connection location is more safe and reliable.It can prevent Short circuit or safety accident caused by rainwater and other factors contact cable lug, can solve existing cable connector lug safety wind Danger, plays the maximum protection to cable lug, and then reach safe effect, guarantees that engineering safety is gone on smoothly.

To sum up, the cable lug protective device of the utility model can protect cable connection location, securely and reliably, design Ingenious, simple for structure, simple installation is quick, is suitable for large-scale promotion application.

It can be seen that the purpose of this utility model completely and is effectively achieved.The function of the utility model and Structural principle is shown and is illustrated in embodiment, and under without departing substantially from the principle, embodiment can make any modification.Institute With the utility model includes all variant embodiments based on claim spirit and scope of the claims.
