Technical Field

The utility model relates to a test upper cover technical field especially relates to a prevent test upper cover that maloperation was opened.

Background

Testing of IC chips requires testing sockets (test sockets) to test the electrical performance and electrical connections of the IC devices to detect manufacturing defects and component defects. With the development of the technology, the requirements on the test seats are higher and higher, and at present, many test seats have the problems that the stress of the test covers is insufficient during testing, the test covers are easy to be operated by people by mistake, poor contact is caused by unconscious opening, and the like.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the existing test cover is not enough in stress when testing by a plurality of test seats in the prior art, and is easy to be operated by people by mistake, unconsciously opens the defect causing bad contact, and provides a test upper cover for preventing misoperation from opening.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a prevent test upper cover that maloperation was opened, includes upper cover plate, float board and apron down, hinged joint between upper cover plate and the apron down, H type opening has all been seted up with the both sides of apron down to the upper cover plate, and first location axle is installed to upper cover plate H type opening one end, and second location axle and axis of rotation are installed respectively to apron H type opening down, first location axle and second location axle are located same one side, and the through-hole has been seted up to the upper cover plate, install the connecting rod in the through-hole, flaky connection piece has been cup jointed at the both ends of connecting rod, first location axle and second location axle run through the connection piece, the connection piece is rotatory around first location axle, and the locking bolt is installed to the one end that the upper cover plate is close to the connecting rod, the locking bolt runs through upper cover plate and connection piece.

Furthermore, the upper cover plate is internally provided with a floating plate through a positioning screw, and the positioning screw is sleeved with a spring washer.

Furthermore, the connection part of the connecting sheet and the first positioning shaft is fixed through a clamp spring.

Further, the connecting piece is made of metal materials which are integrally formed through punching.

Further, the upper cover plate is opened around the rotating shaft.

Furthermore, the connecting rod is locked through a fixing screw, and a gasket is arranged between the fixing screw and the connecting rod.

The utility model has the advantages that: the swivelling joint piece buckle that proposes through this scheme is epaxial at first location axle and second location, compresses tightly downwards, and the increase holding down force makes the upper cover plate inseparabler with the cooperation down between the apron, then rotatory locking bolt is dead the connection piece lock, when opening, unscrews locking bolt earlier then with the hand upwards lifting connecting rod, can open. Thereby avoid testing the upper cover plate and avoided the upper cover plate can be automatic or the maloperation is opened at test or circulation in-process, improve the effect of test.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In this embodiment, referring to fig. 1-2, a test upper cover for preventing incorrect manipulation from being opened includes an upper cover plate 1, a floating plate 2 and a lower cover plate 3, the upper cover plate 1 is hinged to the lower cover plate 3, H-shaped openings are formed in both sides of the upper cover plate 1 and the lower cover plate 3, a first positioning shaft 5 is installed at one end of the H-shaped opening of the upper cover plate 1, a second positioning shaft 6 and a rotation shaft 4 are installed at the H-shaped opening of the lower cover plate 3, the first positioning shaft 5 and the second positioning shaft 6 are located on the same side, a through hole is formed in the upper cover plate 1, a connecting rod 9 is installed in the through hole, a sheet-shaped connecting piece 8 is sleeved at both ends of the connecting rod 9, the first positioning shaft 5 and the second positioning shaft 6 penetrate through the connecting piece 8, the connecting piece 8 rotates around the first positioning shaft 5, a locking bolt 10 is installed at one end of the upper cover plate 1 close to the connecting rod 9, the locking bolt 10 penetrates through the upper cover plate 1 and the connecting piece 8, and the locking bolt 10 is firstly unscrewed, and then the connecting rod 9 is lifted upwards by hand to open the upper cover plate.

As a preferable mode of the present embodiment, the floating plate 2 is mounted inside the upper cover plate 1 through a set screw 14, a spring washer 13 is sleeved on the set screw 14, and the spring washer 13 can play a role of increasing friction force to prevent the floating plate 2 from loosening.

As a preferable scheme of this embodiment, a joint of the connecting piece 8 and the first positioning shaft 5 is fixed by a snap spring 7.

As a preferable mode of this embodiment, the connecting piece 8 is made of a metal material that is integrally formed by punching.

As a preferable mode of the present embodiment, the upper cover 1 is opened around the rotation shaft 4.

As a preferred scheme of this embodiment, the connecting rod 9 is locked through a fixing screw 11, a gasket 12 is arranged between the fixing screw 11 and the connecting rod 9, and the gasket 12 can play a role in increasing friction force, so as to prevent the connecting rod 9 from loosening.

The working principle is as follows: when the test, 8 buckles of rotary connecting piece compress tightly downwards on first location axle 5 and second location axle 6, and the increase holding down force makes the cooperation inseparabler between upper cover plate 1 and the lower cover plate 3, then rotary locking bolt 10 locks connection piece 8 and dies, when opening, unscrews earlier locking bolt 10 and then lifts connecting rod 9 with the hand upwards, can open. Thereby avoid testing upper cover plate 1 and avoided upper cover plate 1 can be automatic or the maloperation is opened at test or circulation in-process, improve the effect of test.

The above, only be the embodiment of the preferred of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, which are designed to be replaced or changed equally, all should be covered within the protection scope of the present invention.
