Description

Technical Field

[0001] This utility model belongs to the field of circuit testing technology, and in particular relates to a test socket with an optimized anti-subjugation structure for the action terminal. Background Technology

[0002] Test sockets are mainly used for testing electrical signals inside circuits such as high-frequency circuit boards. They consist of an insulating base, stationary terminals, and active terminals. During normal circuit operation, the active terminals are in contact with the stationary terminals, and the electrical signal is transmitted normally from the circuit on the active terminal side to the circuit on the stationary terminal side. During testing, a test probe is inserted, causing the probe's probe to contact the active terminal and push it away from the stationary terminal, disconnecting the circuits on both sides of the test socket. The electrical signal is then transmitted from the circuit on the active terminal side through the probe to the testing instrument for signal measurement. With increasing demands for product miniaturization, test sockets need to be lighter and smaller, meaning the size of the active terminals also needs to be smaller. This makes the impact of installation tolerances on the active terminals increasingly significant. Existing test socket structures are prone to situations where the active terminals become excessively deformed and unable to return to their original shape, leading to test socket damage and failure. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a test socket with an optimized anti-subjugation structure for the action terminal.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A test fixture for optimizing the anti-subjugation structure of an actuating terminal includes an insulating base and a conductive terminal structure. The insulating base has a receiving space, and the conductive terminal structure includes an actuating terminal and a stationary terminal disposed in the receiving space. A terminal actuation groove is provided in the insulating base corresponding to the connection area of ​​the actuating terminal and the stationary terminal. The stationary terminal includes a first fixing part and a protruding part extending from one end of the first fixing part to the top of the terminal actuation groove. The actuating terminal includes a second fixing part and an elastic part extending from one end of the second fixing part into the terminal actuation groove. An abutting part is provided at one end of the elastic part, and the abutting part elastically abuts against the protruding part of the stationary terminal. The bottom of the terminal actuation groove below the elastic part is a planar structure, and a probe hole is provided above the elastic part of the insulating base, extending downward from the upper surface of the insulating base to the receiving space.

[0006] Furthermore, the elastic portion includes a first bent portion formed by bending downward from one end of the first fixed portion, and a straight portion extending horizontally or obliquely upward from one end of the first bent portion, one end of the straight portion being bent upward to form an abutment portion.

[0007] Furthermore, the straight section extends obliquely upward from one end of the first bend, and the angle between the straight section and the horizontal direction is 1° to 10°, so that when the elastic section is pushed downward by the probe and comes into contact with the planar structure, the straight section basically coincides with the horizontal direction, so as to provide support for the elastic section and avoid excessive deformation of the elastic section.

[0008] Furthermore, the actuation terminal also includes two side wings that extend horizontally from one end of the second fixing part and are respectively located on both sides of the elastic part, with the lower ends of the side wings abutting against the bottom surface of the receiving space.

[0009] Furthermore, a groove is provided in the middle of the abutting part, and a contact part is formed on both sides of the groove.

[0010] Furthermore, the insulating base includes a lower insulating base and an upper insulating base connected to the lower insulating base. The outer side of the upper insulating base is covered with a shell and connected to the lower insulating base through the shell. The receiving space is formed between the upper insulating base and the lower insulating base. The probe hole vertically penetrates the upper insulating base, and the terminal actuation slot is formed on the lower insulating base.

[0011] Furthermore, the receiving space is a receiving groove formed on the lower insulating base, the operating terminal and the stationary terminal are respectively disposed at both ends of the receiving groove, and the lower end of the upper insulating base abuts against the operating terminal and the stationary terminal; the terminal operating groove is formed in the middle of the receiving groove.

[0012] Furthermore, the lower end face of the lower insulating base is provided with two opening slots facing each other, and the lower end of the outer shell is provided with two first roll-up structures facing each other.

[0013] Furthermore, the first roll-up structure includes a first roll-up portion formed by bending horizontally outward from the outer shell, a second roll-up portion formed by bending downward from one end of the first roll-up portion, and a third roll-up portion formed by bending horizontally inward from one end of the second roll-up portion. The third roll-up portion extends into the opening groove and abuts against and limits the bottom of the groove.

[0014] Furthermore, a first pressing part is provided at the lower end of the upper insulating seat above the first fixing part, and the first pressing part abuts against the first fixing part; a second pressing part is provided at the lower end of the upper insulating seat above the second fixing part, and the second pressing part abuts against the second fixing part.

[0015] In this invention, by changing the structure of the elastic part and the bottom structure of the terminal action groove, the stopping surface of the action terminal is made into a plane. When horizontal misalignment occurs between the action terminal and the lower insulating seat, the distance between the bottom of the action terminal and the bottom of the terminal action groove remains unchanged. This avoids the influence of the assembly accuracy of the action terminal on its deformation during testing and solves the problem that the elastic part cannot return to its original shape due to excessive deformation caused by increased movement distance during testing.

[0035] The following specific examples illustrate the implementation of this utility model. The illustrations provided in the following embodiments are only schematic representations of the basic concept of this utility model. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0036] Please see Figure 1 In existing test sockets, the free end of the actuating terminal 500 is generally an inclined section 910. To prevent excessive deformation of the actuating terminal 500 during movement, the insulating base 900 generally has a slope 920 below the inclined section 910. Please refer to... Figure 2 After the test probe (not shown in the figure) is inserted into the test socket, the probe 930 of the test probe will push the action terminal 500 downward; at this time, the inclined surface 920 will become the stop surface of the action terminal 500, thereby supporting the inclined section 910.

[0037] During the assembly of the actuating terminal 500, due to the influence of assembly precision, a certain degree of misalignment often occurs between the actuating terminal 500 and the lower insulating base 200 in the horizontal direction, which leads to an increase in the distance between the inclined section 910 and the inclined surface 920. Since the dimensions of each component of the test socket are very small, the designed distance between the inclined section 910 and the inclined surface 920 is generally only 0.3mm. However, the assembly tolerance cannot be further reduced due to limitations of existing process conditions. Once a certain degree of horizontal misalignment occurs between the actuating terminal 500 and the lower insulating base 200, the inclined section 910 may undergo excessive deformation due to the increased movement distance after the probe 930 of the test probe is inserted. This deformation may not return to its original shape after the probe 930 is removed, preventing the actuating terminal 500 and the stationary terminal 400 from making tight contact, thus causing the test socket to fail.

[0038] Please see Figure 3 , Figure 3 This is a schematic diagram of an embodiment of a test socket with an optimized anti-subjugation structure for actuated terminals according to this utility model. The test socket with the optimized anti-subjugation structure for actuated terminals in this embodiment includes an insulating base and a conductive terminal structure. Please refer to... Figure 4 , Figure 5 , Figure 6 and Figure 7 The insulating base has a receiving space, and the conductive terminal structure includes an active terminal 500 and a stationary terminal 400 disposed in the receiving space. A terminal actuation groove 220 is provided in the insulating base corresponding to the connection area of ​​the active terminal 500 and the stationary terminal 400 to allow for the movement of the active terminal 500.

[0039] The insulating base includes a lower insulating base 200 and an upper insulating base 100 connected to the lower insulating base 200. The lower end of the upper insulating base 100 may be provided with a plurality of limiting blocks 130. The position of the limiting blocks 130 is adapted to the shape of the receiving groove 210, so that the limiting blocks 130 extend into the receiving groove 210 and contact the side wall of the receiving groove 210, thereby achieving coarse positioning between the upper insulating base 100 and the lower insulating base 200.

[0040] The receiving space is generally formed between the upper insulating base 100 and the lower insulating base 200, and the terminal actuation groove 220 is generally formed on the lower insulating base 200. In this embodiment, the receiving space is a receiving groove 210 formed on the lower insulating base 200, the actuating terminal 500 and the stationary terminal 400 are respectively disposed at both ends of the receiving groove 210, and the lower end of the upper insulating base 100 abuts against the actuating terminal 500 and the stationary terminal 400; the terminal actuation groove 220 is formed in the middle of the receiving groove 210.

[0041] Please see Figure 8 and Figure 9The upper insulating seat 100 is wrapped with a shell 300 and connected to the lower insulating seat 200 through the shell 300. In this embodiment, the lower end face of the lower insulating seat 200 is provided with two opening slots 230 facing each other, and the lower end of the shell 300 is provided with two first roll-up structures 310 facing each other. The first roll-up structure 310 includes a first roll-up portion 311 formed by bending horizontally outward from the shell 300, a second roll-up portion 312 formed by bending downward from one end of the first roll-up portion 311, and a third roll-up portion 313 formed by bending horizontally inward from one end of the second roll-up portion 312. The third roll-up portion 313 extends into the opening slot 230 and abuts against and limits the bottom of the slot 230. The cooperation between the third roll-up portion 313 and the opening slot 230 connects the shell 300 and the upper insulating seat 100 and the lower insulating seat 200 into a whole. The shape of the third roll-up portion 313 is generally adapted to the shape of the opening groove 230, so that the outer shell 300 can be roughly limited by the side wall of the opening groove 230.

[0042] Please see Figure 10 The stationary terminal 400 includes a first fixing portion 410 and an extension portion 420 extending from the first end of the first fixing portion 410 to above the terminal actuation groove 220; the actuating terminal 500 includes a second fixing portion 510 and an elastic portion 520 extending from the second end of the second fixing portion 510 into the terminal actuation groove 220. In this embodiment, a second rolling structure 430 is also provided at the first end of the first fixing portion 410, and a third rolling structure 550 is also provided at the second end of the second fixing portion 510. One end of the elastic portion 520 is provided with an abutment portion 530, which elastically abuts against the extension portion 420 of the stationary terminal 400. A probe hole 110 is provided above the elastic portion 520 on the insulating base, extending downward from the upper surface of the insulating base to the receiving space; in this embodiment, the probe hole 110 vertically penetrates the upper insulating base 100.

[0043] Please continue reading. Figure 5 and Figure 7 The lower end of the upper insulating base 100 is provided with a first pressing part 121 above the first fixing part 410. The first pressing part 121 abuts against the first fixing part 410 to fix the stationary terminal 400 to the right end of the receiving groove 210. The lower end of the upper insulating base 100 is provided with a second pressing part 122 above the second fixing part 510. The second pressing part 122 abuts against the second fixing part 510 to fix the actuating terminal 500 to the left end of the receiving groove 210.

[0044] Please see Figure 5 and Figure 11The elastic portion 520 includes a first bent portion 521 formed by bending downward from one end of the first fixed portion 410, and a straight portion 522 extending horizontally or obliquely upward from one end of the first bent portion 521. One end of the straight portion 522 is bent upward to form an abutment portion 530. The bottom of the terminal actuation groove 220 corresponding to the elastic portion 520 is a planar structure 221, thereby using the plane as the stopping surface of the actuation terminal 500.

[0045] In this embodiment, the straight portion 522 extends obliquely upward from one end of the first bent portion 521, and the angle between the straight portion 522 and the horizontal direction is 1° to 10°, preferably 3° to 5°. When the elastic portion 520 is pushed downward by the probe 930 and comes into contact with the planar structure 221, the straight portion 522 is basically aligned with the horizontal direction, so as to provide support for the elastic portion 520 and prevent excessive deformation of the elastic portion 520. Since the stopping surface of the actuating terminal 500 is a plane, even if there is a horizontal misalignment between the actuating terminal 500 and the lower insulating seat 200, the distance between the bottom of the actuating terminal 500 (i.e., the straight portion 522) and the bottom of the terminal actuating groove 220 (i.e., the planar structure 221) will not change. Therefore, excessive deformation of the elastic portion 520 due to increased movement distance after the probe 930 of the test probe is inserted can be avoided.

[0046] Please continue reading. Figure 11 The actuating terminal 500 may further include two side wings 540 extending horizontally from one end of the second fixing portion 510 and located on both sides of the elastic portion 520, with the lower ends of the side wings 540 abutting against the bottom surface of the receiving groove 210. The two side wings 540 can maintain the overall stability of the actuating terminal 500. A groove 531 is provided in the middle of the abutting portion 530, and a contact portion 532 is formed on both sides of the groove 531, so that the abutting portion 530 and the protruding portion 420 form a two-point contact through the two contact portions 532.

[0047] In this embodiment, by changing the structure of the elastic part 520 and the bottom structure of the terminal actuation groove 220, the stopping surface of the actuation terminal 500 is made flat. When horizontal misalignment occurs between the actuation terminal 500 and the lower insulating seat 200, the distance between the bottom of the actuation terminal 500 and the bottom of the terminal actuation groove 220 remains constant, thereby avoiding the influence of the assembly accuracy of the actuation terminal 500 on its deformation during testing. Therefore, the problem of the elastic part 520 becoming excessively deformed after the probe 930 of the test probe is inserted, resulting in its inability to return to its original shape, is solved.

[0048] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
