Description

Technical Field

[0001] This application relates to the field of PCB technology, and in particular to a connector and insertion loss testing fixture. Background Technology

[0002] A connector is a quick-plug structure that inserts into an SMA (Surface Mount Device) on a PCB for PCB testing. It is suitable for PCB testing in telecommunications, networking, and wireless communication fields. Connectors feature wide bandwidth, superior performance, high reliability, and long lifespan. Common connectors are assembled onto a Coupon (insertion loss connector) using nuts and studs. While this assembly method is reliable and secure, it makes quick assembly and disassembly between the connector and the Coupon difficult, impacting work efficiency. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, this application provides a connector and a test fixture for insertion loss, and the technical solution adopted is as follows.

[0004] The connector provided in this application includes a connector, a base, and a quick-connect structure. The connector is disposed on the base. The quick-connect structure is disposed on the side of the base facing the insertion loss connector. The quick-connect structure is used to insert into a positioning hole arranged along a first direction in the insertion loss connector. After the quick-connect structure is inserted into the positioning hole, the outer periphery of the quick-connect structure can be enlarged and the outer side wall of the quick-connect structure can be engaged with the inner side wall of the positioning hole.

[0005] In some embodiments of this application, the quick-connect structure includes a positioning post and a first snap-fit ​​structure. The first snap-fit ​​structure protrudes from the outer side wall of the positioning post. The positioning post is used to be inserted into the positioning hole. The positioning post is interference-fitted with the inner side wall of the positioning hole through the first snap-fit ​​structure.

[0006] In some embodiments of this application, the outer sidewall of the first snap-fit ​​structure is configured as a spherical surface for contacting the inner sidewall of the positioning hole; or, the outer sidewall of the first snap-fit ​​structure is provided with an inclined first guide surface, and the distance between the first guide surface and the central axis of the positioning post is reduced along the axial direction of the positioning post and away from the base.

[0007] In some embodiments of this application, the quick-connect structure includes at least two second snap-fit ​​structures. The second snap-fit ​​structures are arranged at an angle relative to the first direction. The first end of each second snap-fit ​​structure near the base is fixedly connected, and the second ends of each second snap-fit ​​structure away from the base are separated from each other. The second ends of each second snap-fit ​​structure can approach each other so that the quick-connect structure can be inserted into the positioning hole, and after insertion, the second ends of each second snap-fit ​​structure can move away from each other so that the outer wall of the second snap-fit ​​structure engages with the inner wall of the positioning hole.

[0008] In some embodiments of this application, the first ends of each of the second snap-fit ​​structures are brought close to each other to form a cylindrical structure, and the shape of each of the second snap-fit ​​structures is obtained by dividing the cylindrical structure into at least two equal parts along the axial direction.

[0009] In some embodiments of this application, the quick-connect structure includes a quick-connect sleeve. The sidewall of the quick-connect sleeve is provided with at least two slots along a first direction. The slots extend from one end of the quick-connect sleeve away from the base to the other end, and the extension length of the slots is less than the length of the quick-connect sleeve. The slots are arranged radially through the quick-connect sleeve from the inner sidewall to the outer sidewall. The insertion device is provided with a quick-connect post located in the positioning hole. The quick-connect sleeve is inserted into the positioning hole and sleeved on the quick-connect post. The quick-connect post can open the sidewall of the quick-connect sleeve and engage the sidewall of the quick-connect sleeve with the inner sidewall of the positioning hole.

[0010] In some embodiments of this application, at least one of the inner wall of the quick-connect sleeve and the outer wall of the quick-connect post is configured as a tapered sidewall.

[0011] In some embodiments of this application, at least one of the inner wall of the quick-connect sleeve and the outer wall of the quick-connect post is provided as a smooth wall surface.

[0012] In some embodiments of this application, the quick-connect structure includes a fourth snap-fit ​​structure and a fifth snap-fit ​​structure. The fourth snap-fit ​​structure is disposed on the base, and the fifth snap-fit ​​structure is arranged in the positioning hole. The fourth snap-fit ​​structure and the fifth snap-fit ​​structure are fitted together by an inclined second guide surface. The fourth snap-fit ​​structure is inserted into the positioning hole and tilted under the action of the second guide surface. The quick-connect structure is snapped into the inner wall of the positioning hole by the inclined fourth snap-fit ​​structure.

[0013] In some embodiments of this application, the quick-connect structure is configured as a cylindrical shape, and the quick-connect structure is divided into the fourth snap-fit ​​structure and the fifth snap-fit ​​structure by a slope inclined in a first direction.

[0014] In some embodiments of this application, the second guide surface of at least one of the fourth and fifth snap-fit ​​structures is configured as a smooth wall surface.

[0015] The insertion loss test fixture provided in this application includes an insertion loss test fixture and a connector as described above, wherein the connector is connected to the positioning hole via the quick-connect structure.

[0016] This application has at least the following beneficial effects: The connector in the insertion loss test fixture achieves quick-connect assembly with the insertion loss test fixture through a quick-connect structure that inserts into the positioning hole. The outer periphery of the quick-connect structure increases after insertion into the positioning hole, allowing the outer wall of the end of the quick-connect structure inserted into the positioning hole to apply pressure to the inner wall of the positioning hole, thereby forming a snap-fit ​​between the quick-connect structure and the inner wall of the positioning hole, thus quickly fixing the connector to the insertion loss test fixture. This application can be widely applied in the field of PCB technology.

[0017] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0039] This application relates to an insertion loss testing fixture, combined with the attached... Figure 1-1 The insertion loss test fixture includes an insertion loss connector 1000 and a connector 2000. The connector 2000 is mounted on the insertion loss connector 1000 via a quick-connect structure 3000, so that the connector 2000 can be quickly positioned on the insertion loss connector 1000.

[0040] With the thickness direction of the insertion loss connector 1000 as the first direction, the insertion loss connector 1000 is provided with a positioning hole 1101 extending along the first direction. The positioning hole 1101 is configured as a through hole or a blind hole. Furthermore, the quick-connect structure 3000 of the connector 2000 is inserted into the positioning hole 1101, and the quick-connect structure 3000 can be locked into the inner sidewall of the positioning hole 1101.

[0041] Understandably, the insertion loss connector 1000 is provided with at least one test area 1100 for arranging the connector 2000, and the test area 1100 is provided with a signal hole and a grounding hole. Furthermore, the test area 1100 is provided with at least one positioning hole 1101.

[0042] With the length direction of the insertion loss Kobon 1000 as the second direction, at least two test areas 1100 are distributed at intervals along the second direction, and positioning holes 1101 are respectively provided on both sides of the test area 1100 along the second direction.

[0043] Other components and operations of the insertion loss test fixture are already described in the relevant art for those skilled in the art, and will not be described in detail here. The structure of connector 2000 will be described below.

[0044] This application relates to a connector 2000, in conjunction with the attached... Figure 1-2 The connector 2000 includes a base 2100 and a quick-connect structure 3000. The quick-connect structure 3000 is disposed on the side of the base 2100 facing the insertion plate 1000 and is used to insert into the positioning hole 1101 to assemble the connector 2000 onto the insertion plate. The connector 2000 also includes a connector 2200, which is disposed on the base 2100 and located on the side of the base 2100 away from the insertion plate. Specifically, when the base 2100 is arranged horizontally, the quick-connect structure 3000 and the connector 2200 are located on the lower and upper sides of the base 2100, respectively.

[0045] Furthermore, after the quick-connect structure 3000 is inserted into the positioning hole 1101, the outer periphery of the quick-connect structure 3000 can increase, allowing the outer sidewall of the quick-connect structure 3000 to engage with the inner sidewall of the positioning hole 1101, thereby achieving rapid assembly between the connector 2000 and the insertion loss device 1000. It can be understood that when the quick-connect structure 3000 is inserted into the positioning hole 1101, the diameter of the end of the quick-connect structure 3000 used for insertion into the positioning hole 1101 is smaller than the diameter of that end after insertion into the positioning hole 1101, so that the quick-connect structure 3000 can be easily inserted into the positioning hole 1101. The increased diameter after insertion allows the outer sidewall of that end of the quick-connect structure 3000 to engage with the inner sidewall of the positioning hole 1101.

[0046] It should be noted that, on the side of the base 2100 facing the insertion loss connector 1000, at least one end of the base 2100 is provided with a quick-connect structure 3000. In some examples, quick-connect structures 3000 are provided at both ends of the base 2100, and each quick-connect structure 3000 in the test area 1100 of the insertion loss connector 1000 is provided with a positioning hole 1101. In other alternative examples, one end of the base 2100 is provided with a quick-connect structure 3000, and the other end is provided with a post that serves a positioning function, and both the quick-connect structure 3000 and the post in the test area 1100 of the insertion loss connector 1000 are provided with positioning holes 1101.

[0047] In some implementations, in conjunction with the appendix Figure 2-1 and attached Figure 2-2 The quick-connect structure 3000 includes a positioning post 3101 and a first snap-fit ​​structure 3102. The positioning post 3101 is vertically disposed on the side of the base 2100 and is connected to the base 2100. The first snap-fit ​​structure 3102 protrudes from the outer side wall of the positioning post 3101.

[0048] Specifically, the positioning post 3101 is used to be inserted into the positioning hole 1101. The positioning post 3101 is press-fitted with the inner wall of the positioning hole 1101 through the first snap-fit ​​structure 3102, so that the quick-connect structure 3000 is snapped into the inner wall of the positioning hole 1101.

[0049] Understandably, at least one quick-connect structure 3000 is provided at both ends of the base 2100 to enhance the connection strength between the connector 2000 and the insertion loss Cobond 1000.

[0050] In some examples, at least two first snap-fit ​​structures 3102 are provided at axial intervals on the outer wall of the positioning post 3101 to enhance the snap-fit ​​between the quick-connect structure 3000 and the inner wall of the positioning hole 1101.

[0051] In some examples, combined with appendix Figure 2-1 The outer wall of the first snap-fit ​​structure 3102 is configured as a spherical surface for contacting the inner wall of the positioning hole 1101. Specifically, the first snap-fit ​​structure 3102 is arranged as a spherical protrusion along the circumference surrounding the central axis of the positioning post 3101. Alternatively, spherical protrusions serving as the first snap-fit ​​structure 3102 are respectively provided at symmetrical positions on the outer wall of the positioning post 3101.

[0052] Regarding the first snap-fit ​​structure 3102, at least the following alternative embodiments also exist.

[0053] In some alternative embodiments, in conjunction with the appendix Figure 2-2The outer wall of the first snap-fit ​​structure 3102 is provided with an inclined first guide surface. The first guide surface is inclined relative to the first direction and along the axial direction of the positioning post 3101 and away from the base 2100. The distance between the first guide surface and the central axis of the positioning post 3101 is reduced. Specifically, the outer wall of the first snap-fit ​​structure 3102 of the positioning post 3101 is formed into a conical surface that is larger at the top and smaller at the bottom.

[0054] In some implementations, in conjunction with the appendix Figure 3-1 The quick-connect structure 3000 includes at least two second snap-fit ​​structures 3201. The second snap-fit ​​structures 3201 are arranged at an angle relative to the first direction. The first end of each second snap-fit ​​structure 3201 near the base 2100 is fixedly connected, and the second ends of each second snap-fit ​​structure 3201 away from the base 2100 are separated from each other.

[0055] Furthermore, each of the second snap-fit ​​structures 3201 is elastically bendable. Without external force, each of the second snap-fit ​​structures 3201 of the quick-connect structure 3000 is in its natural state, with the second ends of each second snap-fit ​​structure 3201 separated from each other. When the outer wall of the quick-connect structure 3000 is subjected to pressure, each of the second snap-fit ​​structures 3201 closes, and the second ends of each second snap-fit ​​structure 3201 approach each other.

[0056] Understandably, in conjunction with the appendix Figure 3-2 When the second ends of each second snap-fit ​​structure 3201 are close to each other, the quick-connect structure 3000 can be inserted into the positioning hole 1101. After insertion, the second ends of each second snap-fit ​​structure 3201 can be far apart so that the outer side wall of the second snap-fit ​​structure 3201 is snapped into the inner side wall of the positioning hole 1101.

[0057] In some examples, the first ends of each second snap-fit ​​structure 3201 are brought close together to form a cylindrical structure for insertion into the positioning hole 1101. Furthermore, the shape of each second snap-fit ​​structure 3201 is obtained by dividing the cylindrical structure into at least two equal parts along the axial direction.

[0058] Specifically, in conjunction with the appendix Figure 3-3 (a) The columnar structure is divided into two symmetrical semicircular or fan-shaped columns along the axial direction, and the columns have outward elasticity so that the second ends of each second snap-fit ​​structure 3201 can be separated from each other. Alternatively, the columnar structure is divided into three or four symmetrical fan-shaped columns along the axial direction.

[0059] In some embodiments, the diameter of the positioning hole 1101 is D, and the diameter of the end (i.e. the lower end) of the quick-connect structure 3000 away from the base 2100 when the spacing between the second ends of each second snap-fit ​​structure 3201 is at its maximum is D2, satisfying: D2 > D.

[0060] When the second snap-fit ​​structures 3201 are closed, the diameter of the end of the quick-connect structure 3000 away from the base 2100 does not exceed D, so that the quick-connect structure 3000 can be smoothly inserted into the positioning hole 1101. The quick-connect structure 3000 is designed with D2 > D, which ensures that after the quick-connect structure 3000 enters the positioning hole 1101, the second snap-fit ​​structures 3201 can form a snap-fit ​​force with the inner wall of the positioning hole 1101 during the elastic recovery process.

[0061] In some examples, to ensure that the side of the base 2100 facing the insertion loss 1000 can fit against the surface of the insertion loss 1000, the length of the quick-connect structure 3000 does not exceed the depth of the positioning hole 1101.

[0062] In some implementations, in conjunction with the appendix Figure 4-1 The quick-connect structure 3000 includes a quick-connect sleeve 3301. At least two slots are provided on the sidewall of the quick-connect sleeve 3301 along a first direction. These slots are circumferentially spaced on the sidewall of the quick-connect sleeve 3301. The slots extend radially from the inner sidewall to the outer sidewall of the quick-connect sleeve 3301, thereby dividing the sidewall of the quick-connect sleeve 3301 into at least two sections. Figure 4-4 (a) and (b), the divided sidewalls form a third snap-fit ​​structure 3302.

[0063] The slot extends from one end of the quick-connect sleeve 3301 away from the base 2100 to the other end, and the extension length of the slot is less than the length of the quick-connect sleeve 3301. The slot is formed as a notch at the end of the quick-connect sleeve 3301 away from the base 2100 (i.e., the lower end), so that the divided side walls are connected as one unit at the end of the quick-connect sleeve 3301 near the base 2100 (i.e., the upper end).

[0064] Furthermore, in conjunction with the appendix Figure 4-2 The insertion loss Kobon 1000 is equipped with a quick-connect post 3303 located in the positioning hole 1101. (See attached...) Figure 4-3 The quick-connect sleeve 3301 is inserted into the positioning hole 1101 and sleeved on the quick-connect post 3303. As the quick-connect sleeve 3301 is gradually inserted, the quick-connect post 3303 can open the side wall of the quick-connect sleeve 3301 and make the side wall of the quick-connect sleeve 3301 engage with the inner side wall of the positioning hole 1101.

[0065] In some examples, the quick-connect post 3303 is fixedly disposed in the positioning hole 1101, and the bottom of the quick-connect post 3303 is fixedly connected to the side wall of the positioning hole 1101. In this case, the positioning hole 1101 is set as a blind hole. In other alternative examples, the positioning hole 1101 is set as a through hole. The insertion loss device 1000 is placed flat on the platform, and the quick-connect post 3303 is inserted upright into the positioning hole 1101. The platform supports the quick-connect post 3303. In this case, when the quick-connect sleeve 3301 is sleeved on the quick-connect post 3303, the quick-connect post 3303 can also open the quick-connect sleeve 3301.

[0066] It should be noted that at least one of the inner wall of the quick-connect sleeve 3301 and the outer wall of the quick-connect post 3303 is configured as a tapered sidewall. In some examples, the outer wall of the quick-connect post 3303 is configured as a tapered sidewall. In other alternative examples, the inner wall of the quick-connect sleeve 3301 is configured as a tapered sidewall. In still some alternative examples, both the inner wall of the quick-connect sleeve 3301 and the outer wall of the quick-connect post 3303 are configured as tapered sidewalls.

[0067] Furthermore, if one of the inner wall of the quick-connect sleeve 3301 and the outer wall of the quick-connect post 3303 is set as a tapered sidewall, the other is set as a cylindrical sidewall.

[0068] In some examples, when the outer sidewall of the quick-connect sleeve 3301 is set as a tapered sidewall and the quick-connect post 3303 is set as a cylindrical sidewall, the diameter of the minor diameter end of the quick-connect post 3303 is D4, the diameter of the positioning hole 1101 is D, and the thickness of the sidewall of the quick-connect sleeve 3301 is d, satisfying: D4≤D-2d. That is, D-D4≥2d, thereby ensuring that the sidewall of the quick-connect sleeve 3301 can be inserted into the annular gap between the outer sidewall of the quick-connect post 3303 and the inner sidewall of the positioning hole 1101.

[0069] Understandably, in order to ensure that the side of the base 2100 facing the insertion loss 1000 can fit against the surface of the insertion loss 1000, the length of the quick-connect structure 3000 and the quick-connect post 3303 does not exceed the depth of the positioning hole 1101.

[0070] In some examples, at least one of the inner wall of the quick-connect sleeve 3301 and the outer wall of the quick-connect post 3303 is set as a smooth wall surface to reduce the friction between the quick-connect sleeve 3301 and the quick-connect post 3303, so as to facilitate the quick-connect sleeve 3301 to be quickly inserted into the positioning hole 1101 and improve the assembly efficiency of the connector 2000 and the insertion loss 1000.

[0071] In some implementations, in conjunction with the appendix Figure 5-1The quick-connect structure 3000 includes a fourth snap-fit ​​structure 3401 and a fifth snap-fit ​​structure 3402. The fourth snap-fit ​​structure 3401 is disposed on the base 2100 and is fixedly connected to the base 2100. The fifth snap-fit ​​structure 3402 is arranged in the positioning hole 1101.

[0072] Combined with appendix Figure 5-3 When the fourth snap-fit ​​structure 3401 is inserted into the positioning hole 1101, the fourth snap-fit ​​structure 3401 and the fifth snap-fit ​​structure 3402 are in contact, and the outer wall of the fifth snap-fit ​​structure 3402 applies pressure to the fourth snap-fit ​​structure 3401 inclined in the first direction. As the fourth snap-fit ​​structure 3401 is gradually inserted, the pressure of the fifth snap-fit ​​structure 3402 causes the fourth snap-fit ​​structure 3401 to gradually tilt relative to the first direction, and then the quick-connect structure 3000 engages with the inner wall of the positioning hole 1101 through the tilted fourth snap-fit ​​structure 3401.

[0073] Furthermore, the fourth snap-fit ​​structure 3401 and the fifth snap-fit ​​structure 3402 are attached to each other by an inclined second guide surface. The second guide surface is inclined relative to the first direction. The fourth snap-fit ​​structure 3401 is inserted into the positioning hole 1101 and tilted under the action of the second guide surface.

[0074] It should be noted that the fifth snap-fit ​​structure 3402 can be translated in the positioning hole 1101, the fourth snap-fit ​​structure 3401 pushes the fifth snap-fit ​​structure 3402 through the second guide surface and causes the fifth snap-fit ​​structure 3402 to translate, the fifth snap-fit ​​structure 3402 squeezes the fourth snap-fit ​​structure 3401 through the second guide surface and causes the fourth snap-fit ​​structure 3401 to tilt; or, the fifth snap-fit ​​structure 3402 is fixed in the positioning hole 1101.

[0075] In some examples, the quick-connect structure 3000 is cylindrical, and is divided into a fourth snap-fit ​​structure 3401 and a fifth snap-fit ​​structure 3402 by a slope inclined in a first direction. Further, the inclined slope is formed as a second guide surface on the fourth snap-fit ​​structure 3401 and the fifth snap-fit ​​structure 3402, respectively.

[0076] In some examples, to ensure that the side of the base 2100 facing the insertion loss 1000 can fit against the surface of the insertion loss 1000, the lengths of the fourth snap-fit ​​structure 3401 and the fifth snap-fit ​​structure 3402 do not exceed the depth of the positioning hole 1101.

[0077] In some examples, the diameter of the positioning hole 1101 is D, and the maximum diameter of the structure formed by the mating of the fourth snap-fit ​​structure 3401 and the fifth snap-fit ​​structure 3402 is D5, satisfying D5≥D. This ensures that when the fourth snap-fit ​​structure is inserted into the fifth snap-fit ​​structure, the fourth and fifth snap-fit ​​structures can exert sufficient pressure on the inner wall of the positioning hole, thereby ensuring the snap-fit ​​strength.

[0078] In some examples, the second guide surface of at least one of the fourth snap-fit ​​structure 3401 and the fifth snap-fit ​​structure 3402 is set as a smooth wall surface to reduce the friction between the fourth snap-fit ​​structure 3401 and the fifth snap-fit ​​structure 3402, so as to facilitate the quick insertion of the fourth snap-fit ​​structure 3401 into the positioning hole 1101 and improve the assembly efficiency of the connector 2000 and the insertion loss 1000.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
