[0028] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the utility model, but the utility model can also be implemented in other manners different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of the utility model, therefore the utility model is not limited by the specific embodiments disclosed below.

[0029] As shown in Figure 1 , Figure 2 and Figure 3 , wherein, in order to clearly show the structure, only one of the slide rods 5 is drawn, and the rest are hidden, a construction cable terminal box provided by the embodiments comprises a cuboid shell 1, the top of the shell 1 is open, a cover 2 is detachably arranged on the top of the shell 1, a plurality of insertion slots 14 are arranged on the top end face of the shell 1, and a plurality of insertion rods 21 corresponding to the insertion slots 14 are arranged on the bottom face of the cover 2.

[0030] A base 4 is detachably arranged on the inner bottom face of the shell 1, a plurality of pressing tablet type terminal posts 3, for example, RE-NH4-1P type terminal posts produced by the People's Electrical Appliance Group Co., Ltd., are arranged on the base 4, and external threaded pipes 11 are arranged on the outer sides of two opposite side walls of the shell 1, and internally threaded locking nuts 12 are sleeved on the outer sides of the external threaded pipes 11.

[0031] A first gasket 13 is arranged on the top end face of the shell 1, and a second gasket 16 is sleeved on the outer side of the external threaded pipe 11, which are both used for sealing.

[0032] A plurality of threaded holes 17 are arranged on the top end face of the shell 1, and the cover 2 is provided with avoiding holes corresponding to the threaded holes 17.

[0033] In use, the cover 2 is opened, the cable enters the inside of the shell 1 through the locking nut 12 and the external threaded pipe 11, the pressing tablet of the terminal post 3 is pried, the three wire cores are respectively inserted into the three insertion holes of the terminal post 3, the pressing tablet is pressed, the wire cores are locked in the insertion holes to complete the wiring, then the locking nut 12 is rotated to be threadedly connected and locked with the external threaded pipe 11, the insertion rod 21 of the cover 2 is inserted into the corresponding insertion slot 14 to assist in positioning the cover 2, and then the cover 2 and the shell 1 are fixed to each other through the cooperation of the screw, the avoiding hole and the threaded hole 17.

[0034] Further, since the space inside the shell 1 is small, it is difficult for the fingers to enter the gap between the terminal post and the side wall of the shell 1, and therefore it is difficult to insert the wire core into the insertion hole of the terminal post 3, so generally the base 4 is removed when wiring, and in the prior art, the base 4 is fixed to the bottom face of the shell 1 through four screws arranged at the corners, so that it is troublesome to disassemble and assemble the base 4 and tools are needed.

[0035] In order to make the disassembly base 4 more convenient, the bottom surface of the two long side walls of the rectangular base 4 is provided with a clamping groove 41, the top of the clamping groove 41 extends to the top surface of the base 4, and the bottom surface of the clamping groove 41 is inclined upward near one end of the middle part of the base 4;

[0036] A plurality of dovetail grooves 15 and slide rods 5 corresponding to the clamping groove 41 are arranged on the inner bottom surface of the shell 1, the dovetail grooves 15 and the slide rods 5 extend along the width direction of the shell 1, the bottom end of the slide rod 5 is matched with the dovetail groove 15, the two ends of the slide rod 5 are inclined surfaces, the inclined surface near the end of the base 4 is attached to the bottom surface of the clamping groove 41, and the two end inclined surfaces are complementary, that is, as Figure 4 shown in the structure;

[0037] A plurality of horizontal through holes 141 are arranged on the bottom of the inner side wall of the shell 1, and the plurality of through holes 141 are respectively communicated with the bottom of the plurality of insertion grooves 14.

[0038] The end of the insertion rod 21 away from the base 4 is provided with an armature 51, and the bottom surface of the insertion groove 14 is provided with a magnetic attraction piece.

[0039] The bottom surface of the base 4 and the inner bottom surface of the shell 1 are both provided with a positioning magnetic attraction piece.

[0040] When the base 4 needs to be disassembled from the bottom of the shell 1, the cover 2 is opened, the insertion rod 21 is pulled out of the insertion groove 14, and then the base 4 is pulled out vertically, the bottom surface of the clamping groove 41 pushes the slide rod 5 to move away from the base 4, the end of the slide rod 5 away from the base 4 extends into the inner bottom of the insertion groove 14 through the through hole 141, and the armature 51 is adsorbed with the magnetic piece in the insertion groove 14, after the connection of the cable and the terminal 3 is completed, the magnetic piece on the bottom surface of the base 4 is attached to the magnetic piece on the inner bottom surface of the shell 1, the base 4 is simply positioned, then the insertion rod 21 is inserted into the insertion groove 14, and the installation and fixation of the cover 2 are completed, and for example, after the bottom end of the insertion rod 21 is inserted into the bottom end of the insertion groove 14, the left end of the slide rod 5 is pushed by the bottom end of the insertion rod 21, the slide rod 5 moves towards the base 4, and the right end of the slide rod 5 is inserted into the clamping groove 41, so that the fixation of the base 4 is completed. Figure 3

[0041] Further, as Figure 5 shown, U-shaped rods are arranged on both sides of the top surface of the base 4 as handles 6, so that the base 4 can be conveniently lifted upward from the inside of the shell 1.

[0042] Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present application.​
