Description

Technical Field

[0001] This invention relates to a pin self-locking assembly, an electrical connection device, and a method of using the same. Background Technology

[0002] The rapid development of electronic products has led to their increasingly widespread application in various fields. More and more products are incorporating electronic components to perform their diverse functions, resulting in a gradual increase in the proportion of electronic components in products, with increasingly diverse functions and more complex structures. Therefore, performance testing is particularly important to determine whether electronic components can fulfill their designed functions. During the testing process, the connection structure, as the contact point for interconnection between the test equipment and electronic components, plays a crucial role in power supply conduction and signal transmission. Plug-in connection is a common test connection structure, but during insertion and removal, pins can scratch the surface of the device, and improper insertion and removal operations can easily cause pin bending and other damage. These factors mean that existing test connection structures cannot meet testing requirements. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defect of the plug-in test connection structure in the prior art, which cannot achieve non-destructive testing of electronic devices, and to provide a pin self-locking component, an electrical connection device and its usage method.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] This invention discloses a pin self-locking assembly for fixing pins of electronic components. The pin self-locking assembly includes: a clamping member having an opening for inserting the pin, the clamping member being capable of clamping or releasing the pin; and a locking member configured to switch between a first position and a second position. In the first position, the clamping member clamps the pin; in the second position, the clamping member releases the pin.

[0006] In this design, the pin is inserted into the opening of the clamping member, and the clamping member clamps or releases the pin by changing the size of the opening. When the locking member is in the first position, the clamping member maintains the state of clamping the pin; when the locking member is in the second position, the clamping member can release the pin, allowing the pin to be removed from the clamping member. This structure prevents damage such as pin bending due to improper insertion or removal during the insertion and removal process, and also prevents the pin from scratching the surface of the device.

[0007] Preferably, the pin self-locking assembly further includes an adjusting member having an adjusting hole, and a clamping member disposed within the adjusting hole. The clamping member is movable relative to the adjusting member along the axial direction of the adjusting hole and can change the size of the opening.

[0008] In this design, the size of the clamping member's opening is changed by the relative movement between the clamping member and the adjusting hole. This structural design improves the controllability of the clamping member's opening.

[0009] Preferably, the clamping member includes a first clamping plate and a second clamping plate, wherein the first clamping plate and the second clamping plate are connected to form a V-shaped structure.

[0010] In this solution, the above-mentioned structural form is adopted, the first clamping plate and the second clamping plate are connected to form a V-shaped structure, and the first clamping plate can move relative to the second clamping plate in a direction closer to or farther away from the second clamping plate, so as to change the size of the opening of the V-shaped structure.

[0011] Preferably, the first clamping piece and / or the second clamping piece have a groove at the open end of the V-shaped structure, the groove being adapted to the diameter of the pin;

[0012] And / or, the length of the first clamping piece from the closed end to the open end of the V-shaped structure is greater than the length of the second clamping piece from the closed end to the open end of the V-shaped structure.

[0013] In this design, the contact area between the first and / or second clamping plates and the pins is increased by using grooves that mate with the pins. This structural design improves the stability of the clamping mechanism in clamping the pins. The length of the first clamping plate is greater than the length of the second clamping plate, preventing the pins from failing to be clamped when the two open ends of the V-shaped structure are aligned. This structural design also improves the firmness of the clamping mechanism in clamping the pins.

[0014] Preferably, the pin self-locking assembly further includes a housing, with one end of the clamping member away from the opening extending into the housing, and the locking member disposed within the housing and connected to the clamping member. The housing has a first slot and a second slot, with the first slot located at a first position and the second slot located at a second position. The first slot and the second slot are connected by a guide groove, and the locking member can slide within the guide groove.

[0015] In this design, the housing provides support and fixation for the clamping and locking components, while ensuring their insulation from the external environment. A guide groove connects the first and second slots, facilitating the switching of the locking component between them. The locking component is connected to the clamping component. When the locking component slides within the guide groove, the clamping component moves axially along the adjusting hole, causing the adjusting hole to adjust the opening of the V-shaped structure by squeezing or releasing it. When the locking component moves closer to the first slot, the adjusting hole squeezes the V-shaped structure, reducing its opening. When the locking component is in the first slot, the clamping component clamps the pin and maintains the clamped state. When the locking component moves closer to the second slot, the adjusting hole releases the V-shaped structure, increasing its opening, until it returns to its initial size. When the locking component is in the second slot, the clamping component releases the pin, allowing it to be removed from the clamping component. With the above-mentioned structure, the housing can provide a guide groove for the movement of the locking component while protecting the clamping and locking components. The locking component can also be locked onto the housing. The locking of the locking component and the clamping of the pin can be achieved without additional guide grooves and slots, which improves the compactness of the pin self-locking assembly.

[0016] Preferably, the pin self-locking assembly further includes an elastic element for applying a force to the locking element to slide from the first slot to the second slot.

[0017] In this design, during the movement of the locking member toward the first slot, the elastic member can store energy, and the energy stored in the elastic member reaches its maximum value when the locking member is in the first slot position. When the locking member moves toward the second slot, the elastic member can release the stored energy, ensuring that the locking member can return to the second slot position, thereby causing the clamping member to loosen the pins.

[0018] Preferably, the elastic element is a spring sheet, one end of which is connected to the clamping element, and the other end of which is connected to the housing.

[0019] In this solution, the above-mentioned structure is adopted. The clamping member moves toward the end face of the housing that abuts against the spring, the spring is compressed, and under the action of the spring, the clamping member can spring back to the second position.

[0020] Preferably, the guide groove includes a first guide groove and a second guide groove. The first guide groove is used for the locking member to slide from the second slot to the first slot, and the second guide groove is used for the locking member to slide from the first slot to the second slot. The first guide groove and the second guide groove form a closed loop.

[0021] In this design, the first guide groove and the second guide groove form a closed loop. Using this structure, the locking element can cyclically move between the first and second slots, thereby allowing the clamping element to cyclically clamp and release the pins.

[0022] Preferably, the guide groove includes an inner guide surface and an outer guide surface. The inner guide surface includes a first inner curved surface, a first inner plane, a second inner curved surface, a second inner plane, and a third inner curved surface connected end to end. The third inner curved surface is connected to the first inner curved surface. The first inner plane is parallel to the second inner plane. The second inner curved surface is connected to the second inner plane to form the first slot. The outer guide surface includes a first outer curved surface, a first outer plane, a second outer curved surface, a second outer plane, a third outer curved surface, a third outer plane, and a fourth outer curved surface connected end to end. The fourth outer curved surface is connected to the first outer curved surface to form the second slot. The first outer plane is parallel to the first inner plane and is arranged opposite to it to form a channel. The second outer plane is located below the middle of the second inner curved surface and is parallel to the first outer plane. Both the second outer curved surface and the third outer curved surface extend away from the second slot.

[0023] In this design, the aforementioned structural form is adopted. The first inner curved surface and the first outer curved surface form a downwardly recessed arc-shaped guide groove, facilitating the sliding of the locking component. The first inner plane and the first outer plane form a vertical guide groove, providing greater kinetic energy for the movement of the locking component. The locking component enters the guide groove formed by the gap between the second outer curved surface and the inner guide surface from the vertical guide groove. Because the arc-shaped guide groove is a smooth, downwardly recessed arc, and the locking component generated kinetic energy in the previous stage of movement, the locking component can smoothly slide to the connection point of the second outer curved surface and the second outer plane. When pressing the locking component stops, under the action of the elastic element, the locking component moves along the second outer plane into the second inner curved surface, and then slides along the second inner curved surface into the first slot. Continue pressing the locking member. The locking member slides along the second inner plane and then slides into the third outer curved surface. Then it slides along the third outer curved surface to the connection between the third outer curved surface and the third outer plane. Stop pressing the locking member. Under the action of the elastic member, the locking member slides into the second slot from the arc-shaped guide groove formed by the third outer plane, the fourth outer curved surface and the third inner curved surface.

[0024] Preferably, the locking member includes a guide rod, one end of which is hinged to the clamping member, and the other end of which is slidably connected to the guide groove.

[0025] In this solution, the above-mentioned structure is adopted. Since the first guide groove and the second guide groove form a closed loop, and the guide rod is rotatably connected to the clamping member, the guide rod can slide in the guide groove without the guide rod getting stuck.

[0026] Preferably, the pin self-locking assembly further includes an electrical connector, one end of which is electrically connected to the pin in the clamping member, and the other end of which is used for electrical connection to an external testing device.

[0027] In this solution, the above-mentioned structure is adopted, and the electrical connection between the pins inside the clamping component and the external testing equipment is realized through the electrical connector, thereby enabling performance testing of the pins.

[0028] Preferably, the surface of the clamping member that contacts the pin has a conductive layer, and the electrical connector is electrically connected to the clamping member.

[0029] In this solution, the above-mentioned structural form is adopted, and the conductivity between the pins and the clamping parts is increased through the conductive layer.

[0030] The present invention also discloses an electrical connection device for testing electronic components, comprising a plurality of pin self-locking assemblies, wherein the positions of the plurality of pin self-locking assemblies correspond one-to-one with the positions of the plurality of pins of the electronic component.

[0031] In this solution, each pin self-locking component can independently perform the locking connection function, without being limited by the shape, number, or position of the pin. The self-locking components only need to be arranged according to the characteristics of the pins, and the two components must cooperate with each other. This structural form solves the problem of testing inconvenience caused by the diversity of pins.

[0032] This invention further discloses a method for using an electrical connection device, which connects the electronic component and a testing device. The method includes the following steps: S1, inserting multiple pins of the electronic component into the corresponding multiple pin self-locking components of the electrical connection device, and switching the locking member to the first position to clamp the pins; S2, electrically connecting the electrical connection component corresponding to each pin to an external testing device to test the electronic component; S3, after the test, removing the electrical connection component from the external testing device, switching the locking member to the second position to release the pins, and removing the electronic component from the electrical connection device.

[0033] In this solution, using the aforementioned structure, multiple pins of the electronic component are inserted into the corresponding pin self-locking assemblies of the electrical connection device. Pressing the electronic component causes the guide rod to move from the second slot position to the first slot position. During this movement, the clamping member moves downwards along the axial direction of the adjusting hole, thereby pressing the clamping member and reducing the opening of the V-shaped structure. When the guide rod reaches the first slot, the clamping member clamps the pins, allowing for testing of the electronic component. After testing, pressing the electronic component continues, causing the guide rod to disengage from the first slot. Under the action of the elastic member, the guide rod returns to the second slot position, and the clamping member releases the pins.

[0034] The positive and progressive effects of this invention are as follows:

[0035] By configuring the locking member to switch between a first position and a second position, and ensuring that when the locking member is in the first position, the clamping member holds the pin in place, and when the locking member is in the second position, the clamping member can release the pin, allowing the pin to be easily removed from the clamping member. This structural design prevents damage such as pin bending due to improper insertion or removal during the insertion and removal process, and also prevents the pin from scratching the surface of the device.

[0074] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the following embodiments.

[0075] This embodiment provides a pin self-locking assembly 1 for securing the pins of electronic components. It solves the problems of scratching the device surface during insertion and removal of plug-in test connection structures, and the risk of pin bending or other damage due to improper insertion and removal operations.

[0076] like Figures 1 to 3 As shown, the pin self-locking assembly 1 includes a clamping member 11 and a locking member 12. The clamping member 11 has an opening 111 into which the pin can be inserted, and the size of the opening 111 can be changed to clamp or release the pin. When the locking member 12 is in a first position, the clamping member 11 maintains the state of clamping the pin; when the locking member 12 is in a second position, the clamping member 11 can release the pin, allowing the pin to be removed from the clamping member 11. This structure prevents damage such as pin bending due to improper insertion or removal during the insertion and removal process, and also prevents the pin from scratching the surface of the device. This embodiment is an illustrative representation, using the above structure to achieve pin clamping. In other alternative embodiments, any suitable method can be used.

[0077] In practical use, the size into which the pin can be inserted into the clamping member 11 should be smaller than the length of the pin to avoid contact between the clamping member 11 and structures other than the pin. The clamping member 11 has the function of clamping and connecting the conductive pin, and the material of the clamping member 11 can be a high-performance elastic metal material.

[0078] The pin self-locking assembly 1 also includes an adjusting member 13, which has an adjusting hole 131. A clamping member 11 is disposed within the adjusting hole 131, and the clamping member 11 can move relative to the adjusting member 13 along the axial direction of the adjusting hole 131 to change the size of the opening 111. This structural form improves the controllability of the opening 111 of the clamping member 11.

[0079] In practical use, the adjusting hole 131 can limit the angle and tightness of the opening 111 of the clamping member 11, and the size of the adjusting hole 131 can be determined according to the shape and size of the pin.

[0080] Please see Figure 3 To understand, the clamping member 11 includes a first clamping piece 112 and a second clamping piece 113, and the first clamping piece 112 and the second clamping piece 113 are connected to form a V-shaped structure. With the above structure, the first clamping piece 112 can move relative to the second clamping piece 113 towards or away from the second clamping piece 113 to change the size of the opening 111 of the V-shaped structure.

[0081] In practical use, the first clamping piece 112 and the second clamping piece 113 can be integrally formed. That is, the clamping member 11 is bent to form a V-shaped structure. Of course, in other embodiments, the first clamping piece 112 and the second clamping piece 113 can also be set separately, and the first clamping piece 112 and the second clamping piece 113 can be connected to form a V-shaped structure.

[0082] To improve the stability of the clamping member 11 in clamping the pin, the open end of the V-shaped structure can have the following configurations: First, the first clamping piece 112 has a groove 114 at the open end of the V-shaped structure, while the second clamping piece 113 does not; Second, the second clamping piece 113 has a groove 114 at the open end of the V-shaped structure, while the first clamping piece 112 does not; Third, both the first clamping piece 112 and the second clamping piece 113 have grooves 114 at the open end of the V-shaped structure. In all the above configurations, the groove 114 can be matched to the diameter of the pin.

[0083] In practical use, it is preferable that both the first clamping piece 112 and the second clamping piece 113 have grooves 114 at the open end of the V-shaped structure. This structural design improves the stability of the clamping member 11 in clamping the pins.

[0084] Please see Figure 3 To improve the stability of the clamping member 11 in clamping the pins, the length of the first clamping piece 112 from the closed end to the open end of the V-shaped structure is greater than the length of the second clamping piece 113 from the closed end to the open end of the V-shaped structure. This structural form prevents the pins from failing to be clamped when the two open ends of the V-shaped structure are aligned. This embodiment is illustrative, illustrating how the above structural form improves the stability of clamping the pins. In other alternative embodiments, any suitable method can be used. For example, the length of the second clamping piece 113 from the closed end to the open end of the V-shaped structure is greater than the length of the first clamping piece 112 from the closed end to the open end of the V-shaped structure.

[0085] In practical use, the V-shaped structure is located inside the adjustment hole 131. When the open end of the V-shaped structure moves closer to the adjustment hole 131, the opening 111 of the V-shaped structure will become smaller due to the compression of the adjustment hole 131. When the open end of the V-shaped structure moves away from the adjustment hole 131, the compression force of the adjustment hole 131 on the V-shaped structure decreases, and the opening 111 of the V-shaped structure becomes larger until the opening 111 of the V-shaped structure returns to its initial size.

[0086] Please see Figure 1 and Figure 2To understand the details, the self-locking pin assembly 1 also includes a housing 14, and the end of the clamping member 11 away from the opening 111 extends into the housing 14. A locking member 12 is disposed within the housing 14 and is connected to the clamping member 11. When the locking member 12 slides within the guide groove 141, the clamping member 11 moves relative to the adjusting hole 131 along the axial direction of the adjusting hole 131, allowing the size of the opening 111 of the V-shaped structure to be adjusted by squeezing or releasing the V-shaped structure. The housing 14 has a first slot 1413 located at a first position and a second slot 1414 located at a second position, and the guide groove 141 connects the first slot 1413 and the second slot 1414. The guide groove 141 facilitates the switching of the locking member 12 between the first slot 1413 and the second slot 1414. The locking member 12 is connected to the clamping member 11. When the locking member 12 moves towards the first slot 1413, the adjusting hole 131 compresses the V-shaped structure, and the opening 111 of the V-shaped structure becomes smaller. When the locking member 12 moves towards the second slot 1414, the adjusting hole 131 releases the V-shaped structure, and the opening 111 of the V-shaped structure becomes larger. Finally, the V-shaped structure can return to its initial opening 111 size. When the locking member 12 is in the second slot 1414, the clamping member 11 releases the pin, and the pin can be removed from the clamping member 11. With the above structure, the housing 14, while protecting the clamping member 11 and the locking member 12, can also provide a guide groove 141 for the movement of the locking member 12, and the locking member 12 can also be locked onto the housing 14. The pin clamping can be achieved without additional guide grooves 141 and slots, improving the compactness of the pin self-locking assembly 1. The housing 14 provides support and fixation for the clamping member 11 and the locking member 12, while also ensuring that the clamping member 11 and the locking member 12 are insulated from the outside world.

[0087] In practical use, the material of the housing 14 is not limited to resin or nylon. The extension direction of the housing 14 is the same as the axial direction of the adjustment hole 131, which allows the locking member 12 to move within the housing 14 while the adjustment hole 131 can also adjust the size of the opening 111 of the V-shaped structure.

[0088] Please see Figure 1 and Figure 3To understand further, the self-locking pin assembly 1 also includes an elastic element 15, which can be used to apply a force to the locking member 12 to slide from the first slot 1413 to the second slot 1414. During the movement of the locking member 12 towards the first slot 1413, the elastic element 15 can store energy, and the stored energy reaches its maximum value when the locking member 12 is in the first slot 1413 position. When the locking member 12 moves towards the second slot 1414, the elastic element 15 can release the stored energy, providing energy for the elastic element 15 to rebound. This structural form ensures that the elastic element 15 smoothly completes its rebound. This embodiment is an illustrative representation, using the elastic element 15 to provide the force for the member to return from the first slot 1413 to the second slot 1414. In other alternative embodiments, any suitable method can be used.

[0089] The elastic element 15 is a spring sheet 151, with one end of the spring sheet 151 connected to the clamping element 11 and the other end of the spring sheet 151 connected to the housing 14. With this structure, the clamping element 11 moves towards the end face of the housing 14 that abuts against the spring sheet 151, compressing the spring sheet 151. Under the action of the carbon sheet 151, the clamping element 11 springs back to its initial position. The length, curvature, and other characteristics of the spring sheet 151 are determined based on the pin insertion depth.

[0090] In practical use, the number of spring pieces 151 can be one or more. Increasing the number of spring pieces 151 increases stability, but also increases the difficulty of compressing the spring pieces 151. Preferably, the number of spring pieces 151 is two, and the two spring pieces 151 are arranged in a ring.

[0091] Please see Figure 1 and Figure 2 To understand, the guide groove 141 includes a first guide groove and a second guide groove. The first guide groove is used for the locking member 12 to slide from the second slot 1414 to the first slot 1413, while the second guide groove is used for the locking member 12 to slide from the first slot 1413 to the second slot 1414, and the first and second guide grooves form a closed loop. With this structure, the locking member 12 can cyclically move between the first slot 1413 and the second slot 1414, thereby allowing the clamping member 11 to cyclically clamp and release the pins. This embodiment is illustrative, showing the first and second guide grooves forming a closed loop. In other alternative embodiments, any suitable method can be used. For example, the first guide groove and the second guide groove do not form a closed loop. In use, the clamping member 11 can be moved from the end of the guide groove 141 to the beginning of the guide groove 141 to continue the movement of clamping and releasing the needle; or the clamping member 11 can be moved from the end of the guide groove 141 to the beginning to perform the movement of clamping and releasing the needle.

[0092] Please see Figure 2 To understand, the guide groove 141 includes an inner guide surface 1411 and an outer guide surface 1412. The inner guide surface 1411 includes a first inner curved surface 14111, a first inner plane 14112, a second inner curved surface 14113, a second inner plane 14114, and a third inner curved surface 14115, which are connected end-to-end. The third inner curved surface 14115 is connected to the first inner curved surface 14111. The first inner plane 14112 is parallel to the second inner plane 14114, and the second inner curved surface 14113 is connected to the second inner plane 14114 to form a first slot 1413. The outer guide surface 1412 includes a first outer curved surface 14121, a first outer plane 14122, a second outer curved surface 14123, a second outer plane 14124, a third outer curved surface 14125, a third outer plane 14126, and a fourth outer curved surface 14127, which are connected end-to-end. The fourth outer curved surface 14127 connects with the first outer curved surface 14121 to form the second slot 1414. The first outer plane 14122 is parallel to and opposite to the first inner plane 14112 to form a channel. The second outer plane 14124 is located below the middle of the second inner curved surface 14113 and is parallel to the first outer plane 14122. The second outer curved surface 14123 and the third outer curved surface 14125 both extend away from the second slot 1414. In this design, the first inner curved surface 14111 and the first outer curved surface 14121 form a downwardly recessed arc-shaped guide groove, which facilitates the sliding of the locking member 12; the first inner plane 14112 and the first outer plane 14122 form a vertical guide groove, which can provide greater kinetic energy for the movement of the locking member 12; the locking member 12 enters the guide groove formed by the gap between the second outer curved surface 14123 and the inner guide surface 1411 from the vertical guide groove. Because the arc-shaped guide groove is a smooth, downwardly concave arc, and the locking member 12 generated kinetic energy during the previous stage of movement, the locking member 12 can smoothly slide to the connection point of the second outer curved surface 14123 and the second outer plane 14124. When pressing the locking member 12 stops, under the action of the elastic member 15, the locking member 12 enters part of the second inner curved surface 14113 along the second outer plane 14124, and slides into the first slot 1413 along the second inner curved surface 14113. Continue pressing the locking member 12. The locking member 12 slides along the second inner plane 14114 and then slides into the third outer curved surface 14125. Then it slides along the third outer curved surface 14125 to the connection between the third outer curved surface 14125 and the third outer plane 14126. Stop pressing the locking member 12. Under the action of the elastic member 15, the locking member 12 slides from the arc-shaped guide groove formed by the third outer plane 14126, the fourth outer curved surface 14127 and the third inner curved surface 14115 into the second slot 1414.

[0093] Please see Figure 1To understand the details, the locking element 12 includes a guide rod 121. One end of the guide rod 121 is hinged to the clamping element 11, and the other end of the guide rod 121 is slidably connected to the guide groove 141. With this structure, since the first and second guide grooves form a closed loop, and the guide rod 121 is hinged to the clamping element 11, the clamping element 11 can slide in the guide groove 141, ensuring that the guide rod 121 does not jam.

[0094] In practical use, the guide rod 121 includes a hinged part, a connecting part, and a sliding part, which are connected sequentially. The hinged part is hinged to the clamping member 11, and the sliding part is slidably connected to the guide groove 141. During pin insertion, the guide rod 121 reciprocates within the guide groove 141 on the inner wall of the housing 14, alternately locking at two positions (high and low), thereby achieving a self-locking function.

[0095] Please see Figure 1 and Figure 3 To understand further, the pin self-locking assembly 1 also includes an electrical connector 16, one end of which is electrically connected to the pin within the clamping member 11, and the other end of which is used for electrical connection to external testing equipment. Using this structure, the electrical connector 16 enables electrical connection between the pin within the clamping member 11 and the external testing equipment, thereby facilitating performance testing of the pin.

[0096] In practical use, the clamping part 11, the elastic part 15, and the electrical connector 16 can be integrally formed, eliminating the need for welding and improving the stability of the connection.

[0097] The surface of the clamping member 11 that contacts the pin has a conductive layer, and the electrical connector 16 is electrically connected to the clamping member 11. With this structure, the conductivity between the pin and the clamping member 11 is increased through the conductive layer.

[0098] In practical use, since the clamping member 11, the elastic member 15, and the electrical connector 16 can be integrally formed, the elastic member 15 needs to be conductive. This structural form improves the compactness of the elastic member 15.

[0099] This embodiment also provides an electrical connection device 100 for testing electronic components, such as... Figure 4 and Figure 5 As shown, the electrical connection device includes multiple pin self-locking components 1, and the positions of the multiple pin self-locking components 1 correspond one-to-one with the positions of multiple pins of the electronic component. Each pin self-locking component 1 can independently complete the locking connection function, without being limited by the shape, number, or position of the pin. The pin self-locking components 1 only need to be arranged according to the characteristics of the pins, and the two cooperate with each other. This structural form solves the problem of testing inconvenience caused by the diversity of pins.

[0100] In practical use, the horizontal dimension of the self-locking pin assembly 1 should not be greater than the spacing of the pins, so as to ensure that each unit complements each other and can independently complete the locking function.

[0101] This embodiment further provides a method for using an electrical connection device to connect electronic components and testing equipment. The method includes the following steps: S1, inserting multiple pins of the electronic component into the corresponding pin self-locking assembly 1 of the electrical connection device, and switching the locking member 12 to the first position to clamp the pins with the clamping member 11; S2, electrically connecting the electrical connection member 16 corresponding to each pin to the external testing equipment to test the electronic component; S3, after the test, removing the electrical connection member 16 from the external testing equipment, switching the locking member 12 to the second position to release the pins with the clamping member 11, and removing the electronic component from the electrical connection device. Using the above structure, inserting multiple pins of the electronic component into the corresponding pin self-locking assembly 1 of the electrical connection device and pressing the electronic component causes the guide rod 121 to move from the second slot 1414 position to the first slot 1413 position. During the movement, the clamping member 11 moves downward along the axial direction of the adjusting hole 131, thereby pressing the clamping member 11 and reducing the size of the opening 111 of the V-shaped structure. During this process, the elastic member 15 is compressed. When the guide rod 121 reaches the first slot 1413, the clamping member 11 clamps the pin, allowing for testing of the electronic component. After testing, the electronic component is pressed further, causing the guide rod 121 to disengage from the first slot 1413. The elastic member 15 is released from its restraint, causing it to spring back and move the guide rod, returning it to the second slot 1414 position. The clamping member 11 then releases the pin.

[0102] Please see Figure 4 To understand the performance testing of the InGaAs area array detector, a locking structure was configured based on the pin characteristics. The detector has 21 pins, each with a diameter of φ0.45mm, arranged in a double-row staggered pattern of 10+11 pins, with a row spacing of 1.27mm and a pin spacing of 1.6mm. The self-locking structure configured in this embodiment has a horizontal dimension of 1.6×1.27mm. The housing 14 is made of high-toughness resin and manufactured using 3D printing. The spring piece 151 has a maximum opening spacing of 0.55mm, is made of high-performance spring steel, and is surface-plated with Ni / Au, with the outermost Au layer having a thickness of not less than 0.75μm.

[0103] Please see Figure 5This paper examines the application of the connection and locking structure for InGaAs area array detectors in CLCC / FPA packaging. In this embodiment, the locking structure is configured based on pin characteristics for performance testing of the InGaAs area array detector. The detector has 36 pins, each with a diameter of 0.6 mm, arranged in a single row of 9 pins distributed around the detector, with a pin spacing of 2.54 mm. The self-locking structure configured in this embodiment has a horizontal dimension of 2.4 × 2.4 mm for each unit. The housing 14 is made of high-toughness resin and manufactured using 3D printing. The spring contacts 151 have a maximum opening spacing of 0.55 mm and are made of high-performance spring steel with a Ni / Au plating. The outermost Au layer has a thickness of not less than 0.75 μm. The pins are arranged at 2.54 mm intervals and fixed with epoxy resin to form the external structure shown in the figure.
