Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to fig. 1 to 3 in the embodiments of the present utility model, and it is obvious that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without novel efforts, are intended to fall within the scope of this utility model.
In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "top surface", "bottom surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the indicated positions or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limitations of the present utility model. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1, the test switching fixture disclosed by the utility model is used for connecting a module to be tested and test equipment, and comprises a clamping shell and an electric connection support terminal 400; the clamping shell comprises a back plate 101 and a bottom plate 102, wherein the back plate 101 is used for being fixed at a position to be installed, and the bottom plate 102 is used for placing a module to be tested; the electric connection support terminal 400 penetrates through the bottom plate 102, one end of the electric connection support terminal 400 is in contact with a conductive terminal positioned at the bottom of the module to be tested, and the other end of the electric connection support terminal 400 is connected with test equipment, so that when the module to be tested abuts against the electric connection support terminal 400, the electric connection support terminal 400 is communicated with the module to be tested and the test equipment.
When testing, the module to be tested is placed on the bottom plate 102, one end of the power-on support terminal 400 is connected with the conductive terminal of the module to be tested, and the other end is connected with the testing equipment. Under the action of the gravity of the module to be tested, the power-on support terminal 400 butts against the conductive terminal of the module to be tested, so that quick and reliable electrical connection between the module to be tested and the testing equipment is realized.
The power terminal of the module to be tested can be connected with the testing equipment without wiring, so that the work of wiring and disconnecting is omitted, the problem that repeated wiring and disconnecting are required during batch power module inspection is solved, the testing efficiency and the automation degree of a power product are obviously improved, and the defect that the module to be tested of special package cannot be directly connected through a socket or a connecting wire is overcome.
It should be noted that, except fig. 1, according to the shapes of different modules to be tested, different clamping shells with different shapes can be provided, so that the clearance between the design size of the clamping shell and the external size of the module to be tested is proper.
As shown in fig. 3, in order to protect the conductive connection of the electrical connection support terminal 400, the base plate 102 includes an insulating plate 200, the insulating plate 200 is provided with a through hole, and the electrical connection support terminal 400 passes through the through hole to be fixed on the base plate 102. The electric connection support terminal 400 is directly placed in the through hole reserved in the insulating plate 200, and the electric connection support terminal 400 is not required to be fixed, so that the electric connection support terminal 400 can be replaced later. In practice, bakelite may be used as the material of the insulating plate 200, and other insulating materials may be used. The chemical name of bakelite is phenolic plastic, which is the thermosetting plastic with the largest yield in the world, has higher mechanical strength, good insulativity, heat resistance and corrosion resistance, and is therefore commonly used for manufacturing electrical appliance materials.
The module to be tested is directly placed on the bottom plate 102, in order to make the position of the module to be tested on the bottom plate 102 more firm, set up screens casing and include guard plate 103, guard plate 103 arranges perpendicularly with bottom plate 102, and backplate 101, bottom plate 102 and guard plate 103 enclose into the space that is used for placing the module to be tested. When testing, the module to be tested is placed in the space surrounded by the back plate 101, the bottom plate 102 and the protection plate 103, the placement position can be kept fixed without fixing, and the position of the module to be tested is prevented from shifting in the testing process.
Further, in order to prevent the module to be tested from toppling over, the anti-toppling baffle 104 is arranged on one side of the protection plate 103, opposite to the bottom plate 102, and after the module to be tested is placed in the space surrounded by the bottom plate 101, the bottom plate 102 and the protection plate 103, the module to be tested is located between the anti-toppling baffle 104 and the bottom plate 101, so that toppling over caused by too high and unstable gravity center of the module to be tested is avoided. It should be noted that, in order to facilitate taking the module to be tested, the distance between the anti-toppling baffle 104 and the back plate 101 is greater than the distance between the protection plate 103 and the back plate 101.
If the electrical connection support terminals 400 are of rigid structure, the height is not adjustable, so that the electrical connection between the electrical connection support terminals 400 and the plurality of conductive terminals of the module to be tested is more stable, and it is necessary to ensure that the heights of each electrical connection support terminal 400 higher than the bottom plate 102 are the same, so that the module to be tested is in a balanced state. However, in practice, this method is not easy to implement, and therefore, in an embodiment of the present utility model, a spring probe is selected as the power receiving support terminal 400. Under the action of the elastic force of each spring probe, the module to be tested is easier to maintain in a balanced state. The spring probe is made of environment-friendly hard phosphorus copper nickel plated with hard gold, and is stable in conductivity and wear-resistant.
Taking a module to be tested as a power module for example, the bottom of the power module is provided with a plurality of conductive terminals, the weight of the power module is about 8kg, and the conductive terminals can reliably contact with the head area of the spring probe by the weight of the power module. If the weight of the module to be tested is too large, the spring of the elastic probe is excessively pressed, so that the elastic probe is damaged. In order to prevent the spring of the spring probe from being excessively extruded, a supporting member 300 is disposed on the base plate 102, and the supporting member 300 is located between the base plate 102 and the module to be tested, and is used for supporting the module to be tested, so that the module to be tested is in a balanced state. To ensure the supporting effect of the supporting member 300, the supporting member 300 has a height lower than that of the spring probe.
Further, the supporting member 300 is a screw, the bottom plate 102 is provided with a screw hole in threaded fit with the screw, and the screw is rotated to change the height of the screw relative to the bottom plate 102, so that the height of the supporting member 300 is adjusted, the spring probe is ensured to be in full contact with the conductive terminal, and excessive extrusion of the spring can be prevented.
Alternatively, the support 300 includes a first lever and a second lever, which are locked and fixed by a locking buckle, and the height of the support 300 is adjusted by adjusting the locking buckle.
To better maintain the equilibrium state of the module to be tested, the number of support members 300 is four.
In order to optimize the technical scheme, the heat dissipation holes are formed in the protection plate 103 and/or the back plate 101, so that the heat dissipation holes are beneficial to the heat dissipation of the module to be tested and the test equipment on one hand, and the weight of the whole test switching tool is reduced and the production cost is reduced on the other hand. Meanwhile, the height of the supporter 300 may be adjusted through the heat dissipation holes on the shielding plate 103.
In order to facilitate connection of the power connection support terminal 400 and the test module, a mounting plate 500 is disposed on one side of the base plate 102 opposite to the module to be tested, and a fixing portion for placing the test device is disposed on the mounting plate 500.
A fixing plate is provided as a fixing portion, and the test apparatus is placed on the fixing plate, the fixing plate being parallel to the bottom plate 102. Alternatively, in an embodiment of the present utility model, the guide rail 501 is provided as a fixing portion, and correspondingly, the test device is provided with a slide rail matched with the guide rail 501, so that the fixing and moving of the position of the test device on the mounting board 500 are realized through the matching of the guide rail 501 and the slide rail.
