Abstract

The utility model relates to a transferring terminal for convenient test, which is composed of an insulating casing and electric conductive bodies, wherein the electric conductive bodies are inserted into the casing and are corresponding to binding posts of a terminal one by one, the front ends and the rear ends of the electric conductive bodies are respectively provided with an electric conducting end connected with the binding posts and testing cables, and the casing is also provided with a buckling structure connected with the terminal. Protective testing and controlling devices in the same model can be tested orderly as long as wires of the transferring terminal of the utility model and the testing cables are connected at one time. The utility model avoids the trouble that wires of the testing cables and terminals of protective testing and controlling devices of secondary equipment in an electric power system are connected repeatedly. The testing work efficiency is increased.

Description

The conversion terminal of convenient test

Technical field

The utility model relates to a kind of binding post of conduction, particularly a kind of conversion terminal of convenient test.

Background technology

The binding post that connects electric current, voltage signal amount on the protection measure and control device of secondary equipment in power system; so-called TA/TV terminal; generally have 2 rows, 12 row totally 24 binding posts, binding post mostly is " ten " word grooved screw shape, has the baffle plate of insulation between the adjacent terminal.For the producer that produces the protection measure and control device, each table apparatus all will just can dispatch from the factory through strict test.During test, binding post wiring one by one that need the TA/TV terminal of test cable and tested device is all, after test finishes, take out stitches, again with the TA/TV terminal connections of test cable and another table apparatus, just wiring so repeatedly of test job, take out stitches, operate very loaded down with trivial detailsly, greatly reduce the efficient of test job.

Summary of the invention

Technical problem to be solved in the utility model is that for the protection measure and control device provides a kind of conversion terminal of conveniently testing, test cable and the trouble of installing binding post repetition wiring improve the efficient of test job when testing to exempt.

The technical scheme that its technical problem that solves the utility model adopts is as follows: a kind of conversion terminal of convenient test, it is characterized in that by the housing of insulation and be embedded in the housing with the binding post of binding post one to one electric conductor form, the electric conductor front and back end has the conduction termination that connects binding post and test cable respectively, also has the buckle structure with the binding post clamping on the housing.

The beneficial effects of the utility model are as follows: as long as the utility model conversion terminal and test cable are carried out primary connection; just can test successively the protection measure and control device of same model; as long as promptly this conversion terminal that will connect with test cable successively with the binding post of tested device by in the buckle structure clamping; just can test; test cable and the trouble of installing binding post repetition wiring improve test job efficient when exempting test.

Description of drawings

Fig. 1 is the utility model conversion terminal structural representation (partial cutaway is shown).

Embodiment

With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in further detail.But the utility model is not limited to given example.

As shown in Figure 1, the conversion terminal of the convenient test of the utility model by the housing 1 of insulation and be embedded in the housing with the binding post cruciform slot screw 31 of binding post 3 one to one electric conductor 2 form, electric conductor 2 front and back ends have the conduction termination 21,22 that connects binding post and test cable respectively, also have the buckle structure 4 with binding post 3 clampings on the housing.According to actual needs, the electric conductor in the utility model conversion terminal housing can be for single, also can be for double.33 is insulation barrier between the adjacent terminal of binding post among the figure.

Among the embodiment, spring 23 is housed in the electric conductor 2, preceding conduction termination 21 is aciculiform, is convenient to closely contact with the binding post cruciform slot screw, and conduction termination 22, back is the cylindricality conducting cavity, is convenient to and the supporting grafting of test cable head.During actual the use, preceding conduction termination 21 also can be an elastic spring, conduction termination 22, back also can be can with the screw of test cable wiring.

In embodiment as shown in the figure, can comprise handle 41, spring shaft 42, spring 43 with the buckle structure 4 of binding post 3 clampings, with the framework 44 of insulation shell 1 one, can stick into dop 45, handle and dop trip bolt 46 in the open slot 32 on the binding post 3.By the effect of handle and spring, can be easily this conversion terminal and binding post clamping be integral or unclamp buckle and be separated.

In order to make this conversion terminal and being connected of binding post faster, accurate, reliable, further feature is, as shown in Figure 1, have on this conversion terminal insulation shell 1 with binding post 3 on the insulation barrier 33 corresponding gathering sills of being convenient to locate 11.

Claims

1, the conversion terminal of convenient test, it is characterized in that by the housing of insulation and be embedded in the housing with the binding post of binding post one to one electric conductor form, the electric conductor front and back end has the conduction termination that connects binding post and test cable respectively, also has the buckle structure with the binding post clamping on the housing.
