Description
Technical field
The utility model belongs to a kind of relay characteristic testing stand specific purpose tool, is tried more particularly to a kind of relay characteristic
Test platform fixture.
Background technology
Fixture employed in currently known relay characteristic is tested is since heat dissipation effect is bad, it is necessary to extension lead
To reach the effect of heat dissipation, the accuracy of test data is ensured, this, which has resulted in relay characteristic experiment, can not realize batch
Detection.This fixture manufacturing process is complicated, and the requirement for meeting enterprise is unable in terms of improving detection efficiency and saving cost.
The content of the invention
The utility model provides a kind of achievable batch detection and guarantor to solve technical problem present in known technology
Demonstrate,prove the relay characteristic testing stand fixture of the accuracy of experimental result.
The utility model is adopted the technical scheme that to solve technical problem present in known technology：It includes one
The supporter of a cuboid, 2 fixed columns with screwed hole of centre, the joint cover and 3 screw association parts of 2 L-shaped；
There are two rectangular recess for penetrating into its both sides long side on one oblong lateral surface of the supporter, it is described two long
The length of square groove respectively has one for one is long and the other is short, in the bottom of the rectangular recess and short rectangular recess of the length
Threaded hole, and can distinguish it is each with a bolt by the threaded hole in 2 fixed columns by the supporter and fixed column
String and be together affixed on experiment table top；In one face of a wide joint cover in 2 L-shaped joint covers
Portion, is affixed to the direction vertical with the supporter in the rectangular recess of the length in the supporter, and same described 2
The middle part in one face of another narrow joint cover in a L-shaped joint cover is affixed to described with the direction vertical with the supporter
Described in supporter in short rectangular recess；The wide and narrow joint cover be similarly lean out the supporter side from
By holding upper 3 screw associations that can be used for loading compression or discharging 3 inlet-outlet lines for removing relay to be detected that are connected
Part.
The utility model has the advantages and positive effects of：It is simple in structure, easy to process and installation, wherein connector with
The inlet-outlet line material of relay is identical, and using red copper material, its coefficient of expansion is consistent, be conducive to experiment process repeat circuit and
The heat dissipation of flexible connecting line, has significantly heat dissipation effect, energy especially for heat caused by high-current relay attribute testing
The accuracy of result of the test is enough improved, it is achieved thereby that the batch detection of high-current relay attribute testing, drastically increases
Detection efficiency.

Embodiment
For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates
Attached drawing describes in detail as follows：
As shown in Fig. 1-1,1-2,2-1,2-2,3-1,3-2,4-1,4-2,5-1,5-2,5-3：1 rectangular recess of supporter
The through hole 121 in through hole 111 and rectangular recess 12 in 11 respectively with the through hole 211 and fixed column 22 in fixed column 21
Through hole 221, which is bolted, to be fixed on experiment deck plate (because fixed column 22 is identical with 21 structure of fixed column, therefore Fig. 2-1,2-
The structure diagram of fixed column 21 is only gived in 2).The rectangle that connector 3 and connector 4 are respectively embedded on supporter 1 is recessed
In groove 12 and rectangular recess 11, the threaded hole 31 on connector 3 and the threaded hole 121 in rectangular recess 12 on supporter 1
Fixed by bolted on connection, the threaded hole 41 and threaded hole 42 on connector 4 respectively with the rectangular recess 11 on supporter 1
Threaded hole 111 and threaded hole 112 fixed by bolted on connection.Three identical screw association parts are passed through in three six respectively
Corner bolt is fixed on the threaded hole 43,44 on the threaded hole 32 and connector 4 on connector 3.Pass through precession or back-out three
Screw in screw association part completes the action that three inlet-outlet lines of relay are compressed and discharged with washer respectively.
Wherein connector 3,4 is identical with the inlet-outlet line material of relay, and using red copper material, its coefficient of expansion is consistent,
Be conducive to the heat dissipation of experiment process repeat circuit and flexible connecting line.
