Below in conjunction with drawings and Examples the utility model is described further:

Embodiment 1:

As shown in Figure 1, 2, 3, a kind of electric energy meter test connection device, it is made up of upper and lower two parts, mainboard 1 middle part on top has microscler guide chute hole 2, and there is ratchet 3 two sides, and back plate 6 and contiguous block 5 are an integral body, contiguous block 5 passes slotted eye 2 and band level header board 4 Bolt Connection along 10, constitute slide plate 9, along having hole 11 on 10, the ratchet 8 on the both sides ratchet 3 is fixed on back plate 6 or the header board 4 by the hinge 7 of living; Two ratchets 8 are tightly drawn solid on ratchet 3 by a spring 19, this presses solidly action and also can be finished by two springs, one end is fixed on the mainboard, one end is fixed on the ratchet, if ratchet is thin steel spring plate, also can make ratchet produce elastic deformation, press solidly in the first-class various ways of ratchet and finish by presetting mechanical force to ratchet.

The slide block 12 of lower part can slide along

base

13,12 at least four of slide blocks or above (to be suitable for different phenotypes), select the insulation material for use, have big, the following little coaxial through-hole 15 of diameter of diameter on it, conducting rod 14 inserts through holes 15 and is complementary with following diameter, and afterbody and extraneous flexible cord link, conducting rod 14 tops are with stage clip 16, locknut 21 is threaded with slide block 12, makes conducting rod 14 upper and lowerly to move, and can left and rightly not rock.

During electrical energy meter calibration, earlier the electric energy meter test unit is fixed on the same test installed surface vertical with surface level by holder 22 and base 13, move horizontally the spacing of four slide blocks 12, make conducting rod 14 just in time insert the connection box of electric energy meter hole, and withstand connection terminal in the hole, guarantee passing through of current/voltage, the top hook of electric energy meter is put in level along the hole on 10 11, with hand with level along 10 to pressing down, make slide plate 9 move downward along slotted eye 2, ratchet 8 on the slide plate 9 moves downward along ratchet 3, the downward acting force of both hands is delivered on the conducting rod 14 by electric energy meter, stage clip 16 on the conducting rod 14 is compressed by annular boss 23, because ratchet 3 and ratchet 8 can only one-way movements, therefore, top and lower reaction acting force and the reacting force on electric energy meter makes electric energy meter be connected to the centre securely, finished the wiring action of electric energy meter, after verification finishes, pull handle 20 with hand to both sides, that is: extension spring 19, the artificial power of spring 19 reinforcings on ratchet 8 of removing, shown in Fig. 1 dotted line, ratchet 8 breaks away from ratchet 3, and electric energy meter and slide plate 9 are upspring by the acting force that conducting rod 14 compression springs 16 discharge together, finish the action of taking out stitches, take off electric energy meter and get final product.

Embodiment 2:

As Fig. 4,5, shown in 6, a kind of electric energy meter test connection device, it is by last, following two parts are formed, the mainboard 1 on top is by " C " type holder 22, on, lower plate 18, column 17 is formed, the front opening of " C " type holder 22 is guide chute hole 2, on, lower plate 18 firmly is plugged on " C " type holder 22, down, join together by bolt or welding, column 17 is plugged on, 18 of lower plates, there is ratchet 3 both sides, back plate 6, contiguous block 5, the band level is an integral body " H " type structure along 10 header board 4, forms slide plate 9, slide plate 9 is inserted on the main body 1, can be along on the slotted eye 2, lower slider, ratchet 8 is fixed on the plate 6 of back by the hinge of living, and extension spring 19 presses solidly ratchet 8 on ratchet 3, slide plate 9 is when lower slider, ratchet 8 moves down along ratchet 3, pulls handle 20, and column 17 rotates, ratchet 8 breaks away from ratchet 3, and slide plate 9 possesses the condition that moves upward.

The lower part is identical with embodiment 1 structure, and just conducting rod 14 does not need to fix with locknut with slide block 12.

Its course of work and principle are identical with embodiment 1.
