Description

Technical Field

[0001] The utility model relates to a power supply testing technology, in particular to a test socket of a power supply module. Background Art

[0002] The power module is a very important component of modern electronic devices. It is responsible for power supply and voltage stabilization. In electronic devices, the power module has two main functions: one is to convert and stabilize the input current to meet the voltage and current required for the normal operation of the device; the other is to filter and protect the input power to prevent external factors from damaging the device.

[0003] One of the main functions of a power module is to convert and stabilize the input current. Modern electronic devices usually require different voltages and currents for power supply, and the power module can convert and adjust the voltage and current of the input power supply to meet the needs of the device. For example, household appliances usually use 220V AC power, while electronic devices usually require a lower DC voltage for power supply. The power module can convert 220V AC into the low-voltage DC required by the device.

[0004] The power supply itself has corresponding parameters, but the power supply must be used in conjunction with the load. When the actual power supply is applied to the system, it is often quite different from the power supply's own parameters. Therefore, it is necessary to pay attention to whether each output parameter of the power supply in the actual working process meets the requirements, so as to ensure the normal operation of the product (system). With the large-scale application of power modules, power module testing has become a routine test for many companies. Conventional module testing uses wired alligator clips to clamp onto the test pins, which takes a long time to test and is inconvenient to operate. How to increase the test speed, improve the test reliability, and how to achieve batch module testing have become problems that many companies need to solve.

[0005] Based on the above reasons, it is particularly important to design a simple and easy-to-replace module test socket for the module.

[0006] In view of this, the present utility model is proposed. Utility Model Content

[0007] The purpose of the utility model is to provide a test socket for a power module to solve the above technical problems existing in the prior art.

[0008] The purpose of this utility model is achieved through the following technical solutions:

[0009] The test socket of the power module of the utility model comprises a top and a bottom;

[0019] The following is a clear and complete description of the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, not all of the embodiments, which does not constitute a limitation of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0020] First, the terms that may be used in this article are explained as follows:

[0021] The term “and / or” means that either or both of them can be realized at the same time. For example, X and / or Y means both “X” or “Y” and “X and Y”.

[0022] The terms "include", "comprises", "contains", "has" or other descriptions with similar semantics should be interpreted as non-exclusive inclusion. For example, including certain technical feature elements (such as raw materials, components, ingredients, carriers, dosage forms, materials, dimensions, parts, components, mechanisms, devices, steps, procedures, methods, reaction conditions, processing conditions, parameters, algorithms, signals, data, products or products, etc.) should be interpreted as including not only certain technical feature elements explicitly listed, but also other technical feature elements known in the art that are not explicitly listed.

[0023] The term "consisting of..." means excluding any technical feature elements not explicitly listed. If this term is used in a claim, it will make the claim closed, so that it does not contain technical feature elements other than the technical feature elements explicitly listed, except for the conventional impurities related to them. If this term only appears in a clause of a claim, it only limits the elements explicitly listed in the clause, and the elements recorded in other clauses are not excluded from the overall claim.

[0024] Unless otherwise specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example: it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this article can be understood according to specific circumstances.

[0025] The orientation or position relationship indicated by terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc. are based on the orientation or position relationship shown in the drawings and are only for the convenience and simplification of description, and do not explicitly or implicitly indicate that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation of this document.

[0026] The contents not described in detail in the examples of the present utility model belong to the prior art known to professionals in the field. If no specific conditions are specified in the examples of the present utility model, the conditions are carried out according to the conventional conditions in the field or the conditions recommended by the manufacturer. If the manufacturers of the reagents or instruments used in the examples of the present utility model are not specified, they are all conventional products that can be purchased commercially.

[0027] The test socket of the power module of the utility model comprises a top and a bottom;

[0028] The top portion is provided with a fixing rod and a screw hole, and the bottom portion corresponding to the screw hole is provided with an upper fixing hole, and the top portion and the bottom portion are connected by screws;

[0029] The top is provided with pins, and the bottom is provided with corresponding pin holes;

[0030] The pins at the top are connected to the module to be tested, and the pin holes at the bottom are welded on the circuit board;

[0031] The fixing rod is connected with a spring piece for fixing the module to be tested.

[0032] Each pin includes a thick pin and a thin pin, each pin hole includes a fixed copper sheet and a spring sheet, and the thick pin and the thin pin correspond to the fixed copper sheet and the spring sheet respectively.

[0033] The number of pins and pin holes is compatible with the module test with 2-14 pins.

[0034] From the above, it can be seen that the test socket of the power module in the embodiment of the utility model is universal, easy to replace, and can quickly implement module testing.

[0035] The test seat consists of a top and bottom fixing seat, and the top panel of the test seat consists of a fixing rod and screw holes. When testing the power module, install the module on the test seat, press the fixing clip down to fix it, tighten the test seat spring, and the module can be fixed on the test seat. Then various tests can be performed on the module.

[0036] In the actual test process, the test socket has been assembled, the pins are inserted and soldered to the circuit board, the test module is placed on the upper part of the test socket, and the fixing rod is pressed down to fix the power module. The module test can be carried out.

[0037] During batch testing, only the power module to be tested needs to be replaced each time, which solves the problem that a single power module needs to be fixed with manual wiring clips, which may result in loose fixation and short circuit risks, while also saving testing time.

[0038] In order to more clearly demonstrate the technical solution and technical effects provided by the present invention, the embodiments of the present invention are described in detail with specific embodiments below.

[0039] Example 1

[0040] like Figure 1a , Figure 1b , Figure 2 As shown:

[0041] The top includes a fixing rod and module pin holes, and test socket pins. The bottom includes test socket pin holes and top screw fixing holes. The fixing rod 1 is used to fix the power module. After the fixing rod is pressed down, the module to be tested can be fixed to the test socket; the thin pins 2 and thick pins 3 of the module, the test socket is inserted and welded to the circuit board, and the test socket can be fixed to the circuit board; the power module pin hole 4, the fixing rod is pressed down to fix each pin on the test socket; the top fixing holes 5, 6, 7, 8 of the test socket, with a diameter of 2.5mm, are used to fix the top of the test socket to the bottom of the test socket; another fixing hole 9, 10 for the test socket, with a diameter of 15mm.

[0042] For power modules with small pin spacing, each pin is fixed with a wiring clip during conventional testing. Manual wiring is time-consuming and there are risks such as short circuit of the wiring clip and loose clamp fixation. The utility model designs a test socket based on the characteristics of the power pin spacing to facilitate module insertion. During the test, the test socket is fixed on the circuit board, the module is inserted into the test socket, and then the fixing clip is pressed down to fix the module to be tested, and various functional tests can be performed.

[0043] The utility model designs a circuit board which is convenient for inserting and welding for the test socket pins, and the welding pads on the circuit board are designed for the test socket pins.

[0044] During batch testing, only the power module to be tested needs to be replaced each time, which solves the problem that a single power module needs to be fixed with manual wiring clips, which may result in loose fixation and short circuit risks, while also saving testing time.

[0045] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims. The information disclosed in the background technology section of this article is only intended to deepen the understanding of the overall background technology of the utility model, and should not be regarded as an admission or in any form that the information constitutes prior art known to those skilled in the art.
