Another of Fig. 5 different joints and socket for the utility model uses implemented illustration.

In the drawings, patchboard D, through hole D1, holder 1, sleeve through part 11 wears hole 111, last plane 12, location hole 121, banking stop 13, free end 131, spring element 14, lower plane 15, socket 16, power line 161, energising end 162, lug 163, inserting pole 12, plug 21, pushing and pressing end 22, containing groove 23, latch P1, bolt P2.

See also Fig. 1 and 2, can know and understand structural form of the present utility model, the utility model is made up of the inserting pole 2 that is socketed on the holder 1 on the terminal box D side through hole D1 and is inserted in holder 1 inside: wherein: described holder 1 extends one at side just can pass the sleeve through part 11 of terminal box through hole D1, and forms the hole that wears of an oblate shape in the sleeve through part: to be positioned at the opposite side of terminal box D be to be L shape platform to holder 1 again; 12 both sides, last plane of this platform are respectively equipped with location hole 121, and are provided with banking stop 13 for latch P1 pivot on the location hole 121, make that banking stop 13 can the articulated section be the turn of fulcrum appropriateness; This banking stop 13 engages a spring element 14 that connects two banking stops at its free end 131 again, and spring element 14 just can be free end 131 tensions of two banking stops the state of compression when normality.

Described platform-lower plane 15 is the last planes 12 of being longer than platform, and lower plane 15 ends are then for bolt P2 is locked on socket 16, and make socket 16 just be positioned at guide vane end stop 13 rear ends; Socket 16 1 sides are provided with power line 161 again, and opposite side then forms the energising end 162 that plugs for joint, and socket 16 both sides are respectively equipped with lug 163, pass lug 163 for bolt P2, and socket 16 lockings are located at the lower plane 15 of holder;

Described inserting pole 2 is to be the oblate shape body of rod structure that involutory holder wears hole 111, can be socketed on wearing in the hole 111 of holder so that inserting pole 2 to be provided; Inserting pole 2 front ends are equipped with plug 21 again, and inserting pole 2 ends form the pushing and pressing end 22 that slightly protrudes side, pushing and pressing end 22 sides then form a containing groove 23, after supplying inserting pole 2 to plug, its pushing and pressing end 22 just can plug together on socket 16 joint 21 the free end 131 past extrapolations of banking stop, and containing groove 23 then just can hold the banking stop 13 of homing, and make inserting pole 2 be subjected to the backstop of banking stop 13, and can't withdraw from toward Hou.

Its concrete mode of operation is, please refer to Fig. 3, and D is under normality for this terminal box, and the free end 131 of banking stop is the state (as shown in Figure 3A) of compression for spring element 14 tensions.When inserting pole 2 is inserted by the sleeve through part 11 of holder, the pushing and pressing end 22 of inserting pole 2 can appropriate push against the free end 131 of banking stop outward, support the spring element 14 that is fixedly arranged on banking stop 13 free ends top to turn round to stretch, can penetrate (shown in Fig. 3 B) by wearing hole 111 for inserting pole 2.

After the joint 21 of inserting pole 2 cooperates insertion socket 16, the pushing and pressing end 22 of inserting pole is by banking stop 13 and spring element 14, but make spring element 14 reinstatements, the past once again interior clamping to drive banking stop 13 homings, make inserting pole 2 by banking stop 13 be subjected to banking stop 13 backstops and can't withdraw from backward, and be limited in (shown in Fig. 3 C) on the holder 1 with joint 21.

For this reason, after confession inserting pole 2 directly inserts the sleeve through part 11 of holder, can locate with holder 1, and need not cooperate locks such as locking other bolt to establish instrument again, reach the effect of simple and convenient assembly according to this.

Please cooperate again and consult Figure 4 and 5, the utility model can cooperate different types of socket and joint to use, and wherein, the socket 16 of Fig. 4 is the inserting hole forms that are small one and large one, and the mating side that cooperates joint 21 also is small one and large one structural form, so that the grafting conducting to be provided.The socket 16 of Fig. 5 is to be single inserting hole form, cooperates the mating side of this joint 21 also to be the single hole state, plugs together conducting person to provide.

In addition, the hole D1 that wears of described terminal box can be triangular in shape, other equivalent polygonal holes body structures such as rectangle, pentagon.
