Description

Technical Field

[0001] This utility model relates to the field of coaxial RF connector probe structures, and in particular to a coaxial RF connector probe that can be quickly assembled and disassembled. Background Technology

[0002] Coaxial RF connector probes are RF coaxial probes used in connector assemblies. They are a type of measurement device used to measure the RF signals of electronic circuits in electronic components such as silicon wafers, dies, and open-chip microchips. For ease of explanation, the coaxial RF connector probes will be referred to as "probes" in the following text.

[0003] With the iterative updates of communication technology, the requirements for the "contact reliability and maintainability" of probes are increasing. At present, by adopting the "serrated contact head" and "floating" design, the technical problem of poor contact caused by the height difference and shape difference of electronic components can be effectively overcome, thus improving the test accuracy.

[0004] However, in the current existing technical solutions, the contact pin at the front end and the inner conductor connected to the contact pin are both encapsulated in an integrated housing. The core components such as the contact pin and the housing (outer conductor) will wear and oxidize due to high-frequency contact. Furthermore, because the integrated housing and the contact pin are connected to the inner conductor by riveting, the parts cannot be replaced individually. Once the probe or housing is damaged, the entire unit must be replaced, resulting in serious waste of resources. It is also difficult to flexibly replace parts according to testing requirements, resulting in poor adaptability to different electronic components.

[0005] Therefore, in order to solve the technical problem of parts being difficult or even impossible to replace, it is necessary to improve the probe structure. Utility Model Content

[0006] The purpose of this utility model is to provide a coaxial RF connector probe that can be quickly disassembled and assembled, which can effectively solve the technical problem that parts are difficult or even impossible to replace, thereby reducing resource waste and improving compatibility.

Under the action of the second elastic element or the action of the inner conductor, the annular limiting part of the second insulator abuts against the step of the stepped hole to restrict relative axial movement between the second insulator and the inner wall of the third housing. Or / and the contact pin has a front section and a rear section with a diameter greater than that of the front section, the rear section being inserted into the insertion hole and the front section being inserted into the second insulator; under the action of the second elastic member, the rear section abuts against the rear end face of the second insulator to limit the relative axial movement between the contact pin and the second insulator.

[0012] Furthermore, it also includes a second housing, which is coaxially fitted around the first and third housings. The inner wall of the second housing, the outer wall of the first housing, and the rear end of the third housing form a floating cavity. A first elastic element is installed in the floating cavity. The first elastic element is fitted onto the first housing and its two ends act on the rear end of the third housing and the inner wall of the second housing, respectively. A connecting flange is provided on the second housing, and the connecting flange has a connecting hole.

[0013] Furthermore, a limiting platform is provided on the inner wall of the second housing, and the limiting platform is attached to the outer wall of the third housing; The rear end of the second housing has a tapered hole section, and the first housing has a tapered section of the same taper at the position where it connects to the hole section.

[0014] Furthermore, the hole segment has a small-diameter end and a large-diameter end, with the small-diameter end being closer to the front end than the large-diameter end, and the small-diameter end or the large-diameter end of the hole segment has a straight section of the same diameter, which can fit against the outer wall of the first housing.

[0015] Furthermore, the connection assembly also has a first insulator assembled between the inner wall of the first housing and the inner conductor, and the first insulator supports the contact pin such that the axis of the contact pin is coaxial with the inner wall of the third housing; an axial fixing structure is provided between the inner conductor and the first insulator, and between the first insulator and the inner wall of the first housing, to axially fix the inner conductor and the first insulator, and the first insulator and the first housing.

Detailed Implementation

[0020] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification, unless otherwise stated, may be replaced by other equivalent or similar features. That is, unless otherwise stated, each feature is merely one example of a series of equivalent or similar features.

[0022] In the description of this specification, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, they are only for the convenience of describing this specification and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this specification.

[0023] In the description of this specification, it should also be noted that, unless otherwise expressly specified and limited, the terms “set up,” “install,” “connect,” and “link” should be interpreted broadly. For example, a link can be a fixed link, a detachable link, or an integral link; it can be a mechanical link or an electrical link; it can be a direct link or an indirect link through an intermediate medium; it can be a connection within two components.

[0024] like Figures 1-4 As shown, for a probe, the end connected to the connector is usually called the rear end, and the end used to contact electronic components is called the front end. Therefore, the coaxial RF connector probe that can be quickly assembled and disassembled disclosed in this embodiment includes a contact assembly located at the front end and a connection assembly located at the rear end. The contact assembly has a third housing 3 and a contact pin 1 assembled in the third housing 3. The connection assembly includes a first housing 6 and an inner conductor 4 assembled in the first housing 6. The third housing 3 is detachably connected to the first housing 6, and the contact pin 1 is detachably connected to the inner conductor 4.

[0025] In this embodiment, the detachable connection between the first housing 6 and the third housing 3, and the detachable connection between the contact pin 1 and the inner conductor 4, is achieved between the contact assembly at the front end and the connection assembly at the rear end. This effectively solves the technical problem of parts being difficult or even impossible to replace, thereby reducing resource waste and improving compatibility. Specifically, if a part in the contact assembly is damaged, the connection between the first housing 6 and the third housing 3, and the connection between the contact pin 1 and the inner conductor 4, can be disassembled to replace the contact assembly without scrapping the connection assembly at the rear end, thus reducing resource waste. Furthermore, if it is necessary to replace the contact assembly with another compatible electronic component, the original contact assembly can be disassembled and replaced with a compatible one.

[0026] Based on the above structure, further design is required to achieve the requirements of the above structural design and the expected purpose. The details are as follows.

[0027] In one feasible implementation, the rear end of the third housing 3 is threadedly connected to the front end of the first housing 6, thereby achieving a detachable connection between the third housing 3 and the first housing 6. Specifically, the third housing 3 is provided with an internal thread, and the first housing 6 is provided with an external thread. The internal thread and the external thread are threadedly connected to achieve a detachable connection, and the axes of the third housing 3 and the first housing 6 are collinear.

[0028] In one feasible implementation, the inner conductor 4 has a socket 41 at its front end, and the rear end of the contact pin 1 is inserted into the socket 41. The inner conductor 4 and the contact pin 1 are detachably connected by the insertion, and the axis of the contact pin 1 and the inner conductor 4 are collinear.

[0029] In one feasible implementation, the contact assembly further includes a second insulator 72 mounted between the inner wall of the third housing 3 and the contact needle 1, and the second insulator 72 supports the contact needle 1 such that the axis of the contact needle 1 is coaxial with the inner wall of the third housing 3; in fact, the third housing 3 and the first housing 6 act as outer conductors in the probe, and the outer conductor and the inner conductor 4 are equivalent to the positive and negative poles of the electrodes; by supporting the contact needle 1 with the second insulator 72, the contact needle 1 will not come into contact with the third housing 3, thereby avoiding the formation of a signal current loop between the contact needle 1 and the third housing 3.

[0030] It should be noted that the third housing 3 and the first housing 6 are collinear, the contact pin 1 and the inner conductor 4 are collinear, and the contact pin 1 and the third housing 3 are collinear. Together, they achieve the goal of a coaxial assembly structure where the third housing 3, the contact pin 1, the second housing 5 and the inner conductor 4 are all collinear. The effect of coaxiality is well known in the art and will not be elaborated further here.

[0031] As described above, a feasible implementation method allows the contact pin 1 to move axially. To achieve axial movement and reset, and to ensure the stability of the contact pin 1's tip contacting the electronic component, the socket 41 can be countersunk, and a second elastic element 42 can be provided between the rear end of the contact pin 1 and the bottom of the socket 41. After assembly, the contact pin 1 has an axial movement stroke. The second elastic element 42 allows the contact pin 1 to maintain its floating ability axially. On the other hand, the contact pin 1 is subjected to the elastic force of the second elastic element 42, which makes the contact pin 1 have a contact force with the electronic component, ensuring stable contact and improving the continuity and stability of signal acquisition.

[0032] Furthermore, a limiting structure is provided between the contact pin 1 and the second insulator 72, and between the second insulator 72 and the inner wall of the third housing 3, to limit relative axial movement between the contact pin 1 and the second insulator 72, and between the second insulator 72 and the inner wall of the third housing 3; the limiting structure restricts the extreme positions of the contact pin 1 and the second insulator 72, preventing the connection between the contact pin 1 and the inner conductor 4 from breaking, ensuring that the contact pin 1 is always inserted into the inner conductor 4, and even if the contact pin 1 undergoes axial displacement, it can still stably contact the inner conductor 4.

[0033] In one feasible implementation, the second insulator 72 is a T-shaped cylindrical structure with an annular limiting part at its rear end. The third housing 3 has a stepped hole 31 at the position where it connects to the second insulator 72. Under the action of the second elastic member 42 or the inner conductor 4, the annular limiting part of the second insulator 72 abuts against the step of the stepped hole 31 to limit the relative axial movement between the second insulator 72 and the inner wall of the third housing 3.

[0034] Of course, the second insulator 72 may not have axial displacement after installation. That is, the second insulator 72 can be clamped by the inner conductor 4 against the end face of the second insulator 72 and the step of the stepped hole 31, so as to fix the second insulator 72.

[0035] In one feasible implementation, the contact pin 1 has a front section 11 and a rear section 12 with a diameter larger than that of the front section 11. The rear section 12 is inserted into the insertion hole 41, and the front section 11 is inserted into the second insulator 72. Under the action of the second elastic member 42, the rear section 12 abuts against the rear end face of the second insulator 72 to limit the relative axial movement between the contact pin 1 and the second insulator 72. This can both realize the axial sliding of the contact pin 1 and limit the extreme position of the contact pin 1.

[0036] It should be noted that whether it is the axial displacement of the contact pin 1 or the axial displacement of the second insulator 72 with the contact pin 1, it is all done in conjunction with the second elastic element 42 to achieve the floating effect and ensure the contact stability of the contact pin 1. Of course, when the second insulator 72 is locked, the contact pin 1 and the second insulator 72 can be designed to slide along the axial direction, which can also achieve the floating effect of the contact pin 1.

[0037] In another embodiment, for the "annular limiting part of the second insulator 72 abuts against the step of the stepped hole 31", the second elastic member 42 acts on the rear section 12 of the contact pin 1, and the rear section 12 acts on the second insulator 72 so that the annular limiting part of the second insulator 72 abuts against the step of the stepped hole 31.

[0038] In terms of assembly, this structure allows for the detachable connection of the contact pin 1, the second insulator 72, and the third housing 3 in the contact assembly, enabling targeted replacement of parts. If the contact pin 1 is damaged, only the contact pin 1 needs to be replaced, without replacing the entire contact assembly, thus saving resources. At the same time, since the second elastic element 42 is used to replace the original riveting connection method to achieve assembly constraints, assembly is more convenient. During assembly, the second insulator 72 is coaxially placed into the third housing 3, and the front section 11 of the contact pin 1 is coaxially inserted into the second insulator 72 to complete the assembly of the contact assembly. The rear section 12 of the contact pin 1 is inserted into the countersunk hole, and the third housing 3 is threadedly connected to the first housing 6 to achieve a detachable connection between the contact assembly and the connection assembly.

[0039] In one feasible implementation, the probe further includes a second housing 5, which is coaxially fitted around the first housing 6 and the third housing 3. The inner wall of the second housing 5, the outer wall of the first housing 6, and the rear end of the third housing 3 form a floating cavity 52. ​​A first elastic member 51 is installed in the floating cavity 52. ​​The first elastic member 51 is fitted onto the first housing 6 and its two ends act on the rear end of the third housing 3 and the inner wall of the second housing 5, respectively. A connecting flange is provided on the second housing 5, and the connecting flange has a connecting hole 53.

[0040] In this embodiment, the second housing 5 is provided to facilitate installation, that is, the second housing 5 is fixedly installed on the connector using the connection hole 53.

[0041] Furthermore, by connecting the second housing 5 with the first housing 6 and the third housing 3, and in conjunction with the first elastic element 51, the first housing 6 and the third housing 3 can float as a whole. As outer conductors, the first housing 6 and the third housing 3 also have a floating effect, thereby improving the stability of probe contact.

[0042] In one feasible implementation, a limiting platform 54 is provided on the inner wall of the second housing 5. The limiting platform 54 is an annular structure and is attached to the outer wall of the third housing 6. The limiting platform 54 is used to constrain the radial displacement of the third housing 3, ensuring that the axis of the third housing 3 is collinear with the axis of the second housing 5. At the same time, the limiting platform 54 is also used to support the third housing 3.

[0043] In one feasible implementation, the rear end of the second housing 5 has a tapered hole section 55, and the first housing 6 has a tapered section 61 with the same taper at the position where it connects to the hole section 55. Utilizing the self-guiding function of the tapered structure, the tapered hole section 55 on the second housing 5 and the tapered section 61 on the first housing 6 are constrained and guided, allowing the axis of the first housing 6 to adaptively become collinear with the axis of the second housing 5. For the overall connection between the first housing 6 and the third housing 3, this achieves adaptive collinearity reset after the entire structure floats, and, in conjunction with the supporting effect of the limiting platform 54 on the third housing 3, achieves the effect of the second housing 5 supporting the overall connection between the first housing 6 and the third housing 3.

[0044] Furthermore, the hole segment 55 has a small-diameter end and a large-diameter end, with the small-diameter end being closer to the front end than the large-diameter end. The small-diameter end and / or the large-diameter end of the hole segment 55 have straight segments 56 of the same diameter, meaning the diameter of the straight segment 56 at the small-diameter end matches the diameter of the small-diameter end, and the diameter of the straight segment 56 at the large-diameter end matches the diameter of the large-diameter end. The straight segment 56 can fit against the outer wall of the first housing 6. Through the cooperation of the hole segment 55 and the tapered segment 61, the first housing 6 is guided to fit against the straight segment 56, thereby forming a more stable radial constraint and effectively improving the adaptive collinearity reset stability after overall floating. Simultaneously, since the small-diameter end of the hole segment 55 is closer to the front end than the large-diameter end, it restricts the overall reset position.

[0045] It should be noted that the cooperation between the limiting platform 54 and the third housing 5 or the cooperation between the hole segment 55 and the conical segment 61 can theoretically achieve the overall floating and collinear reset. However, since there is only one support point, it is easy for tilting and swaying to occur during the reset process. Therefore, it is preferable that the cooperation between the limiting platform 54 and the third housing 5 and the cooperation between the hole segment 55 and the conical segment 61 coexist. This can limit the tilting of the whole during floating and reset due to the presence of the straight segment 56, and can automatically guide the collinear reset and limit the position after reset due to the presence of the hole segment 55, thus having stronger coaxial stability.

[0046] In one feasible implementation, the connecting assembly further includes a first insulator assembled between the inner wall of the first housing 6 and the inner conductor 4, and the first insulator supports the contact pin 1 such that the axis of the contact pin 1 is coaxial with the inner wall of the third housing 3; an axial fixing structure is provided between the inner conductor 4 and the first insulator, and between the first insulator and the inner wall of the first housing 6, to axially fix the inner conductor 4 and the first insulator, and the first insulator and the first housing 6.

[0047] As mentioned above, the third housing 3 and the first housing 6 actually function as outer conductors in the probe. The inner conductor 4 is supported by the first insulator, so that the inner conductor 4 will not come into contact with the first housing 6, thus avoiding the formation of a signal current loop between the outer conductor and the first housing 6. At the same time, the first insulator supports the inner conductor 4, and the second insulator 72 supports the contact needle 1. The contact needle 1 is coaxially connected with the inner conductor 4, so that the first insulator and the second insulator 72 jointly support the contact needle 1 and the inner conductor 4 to form a whole.

[0048] Furthermore, for fixed structures, the details are as follows.

[0049] For the inner conductor 4 and the first insulator, the rear end of the inner conductor 4 passes through the first insulator. A first fixing ring groove is provided on the inner wall of the first insulator, and a first fixing ring platform 43 is provided on the inner conductor 4. The first fixing ring platform 43 is located in the first fixing ring groove.

[0050] The first fixing ring 43 is embedded in the first fixing ring groove to achieve axial fixation of the first insulator and the inner conductor 4. At the same time, since the embedded size is small and the first insulator is an elastic material that can produce slight deformation, when installing the inner conductor 4, the inner conductor 4 can be directly inserted into the first insulator until the first fixing ring 43 is embedded in the first fixing ring groove. When removing the inner conductor 4, the inner conductor 4 can be directly pulled out from the first insulator.

[0051] For the first insulator and the first housing 6, a second fixing ring platform 62 is provided on the inner wall of the first housing 6, and a second fixing ring groove is provided on the outer wall of the first insulator. The second fixing ring platform 62 is located in the second fixing ring groove. The axial fixing of the first insulator and the first housing 6 is in the same principle as the axial fixing of the inner conductor 4 and the first insulator, and will not be explained further here.

[0052] As can be seen from the above, the inner conductor 4, the first insulator and the first housing 6 can be axially fixed, and the installation is convenient. At the same time, the parts can be disassembled for easy replacement.

[0053] In one feasible implementation, the rear end of the inner conductor 4 is provided with a plug notch for connection with a connector. This plug interface is a basic structure of all probes and belongs to the prior art. Therefore, it will not be described in detail in this specification.

[0054] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
