Description

Technical Field

[0001] This invention relates to the field of fixture technology, and more specifically to a fixture for contact connectors and an installation and testing device for contact connectors. Background Technology

[0002] Contact connectors, a new type of flexible end-face contact component, consist of plug connectors and socket connectors. As a solderless, low-profile, and highly integrated interconnection method, they integrate radio frequency, signal, or ground shielding functions into one unit. They meet the requirements for vertical interconnection between different functional modules in a stack-up configuration, significantly reducing system weight and size, and improving system reliability and maintainability. They are widely used in various devices to carry data transmission and signal interconnection between circuits.

[0003] The current design for assembling contact connectors primarily uses mounting screws to fix them to the mounting holes on the printed circuit board (PCB). However, because the diameter of the PCB mounting holes is larger than the diameter of the mounting screws, this excess allowance means that the screws cannot be centered within the PCB mounting holes after installation. This results in misalignment between the mounting screws and the PCB mounting holes, causing misalignment between the contact connector signal pins and the PCB surface mount pads. The larger the misalignment, the worse the link's RF performance becomes, leading to significant insertion loss and reduced high-frequency signal quality. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that after the contact connector is assembled, the signal pins are easily misaligned with the surface-mount pads of the printed circuit board, resulting in a deterioration of the link RF performance. The purpose is to provide a clamp for contact connectors and an installation and testing device for contact connectors to solve the above-mentioned problems.

[0005] This invention is achieved through the following technical solution: In a first aspect, the present invention provides a clamp for a contact connector, comprising: The fixture body has a slot for connecting a contact connector; Alignment pins are slidably mounted on the fixture body and are used for fixing and positioning the contact connector.

[0006] In one possible design, the fixture body is equipped with a telescopic structure for adjusting the size of the slot.

[0007] In one possible design, the fixture body includes a first plate, a second plate, and a third plate; The first plate is connected to a second plate at each end, and correspondingly, there are two second plates arranged opposite to each other. Each second plate is connected at both ends to the end of the first plate and the third plate, so that the first plate and the third plate are opposite to each other and parallel. Accordingly, there are two third plates. Accordingly, the first plate, the second plate, and the third plate form the slot; the first plate and the second plate are respectively provided with the telescopic structure.

[0008] In one possible design, the telescopic structure includes a telescopic shaft and a first locking screw; The telescopic shaft includes a sleeve that passes through the plate body and a sub-sleeve that is slidably disposed on the sleeve. There is at least one sub-sleeve. When there are multiple sub-sleeves, the sub-sleeves are inserted into each other from the inside to the outside. The first locking screw is located on the plate and is offset from the sleeve. The first locking screw is used to fix the sub-sleeve. Accordingly, the plate body includes a first plate body and a second plate body.

[0009] In one possible design, the first plate has two spaced telescopic structures, and the portion of the first plate located between the two telescopic structures is configured as a positioning area for connecting the alignment post.

[0010] In one possible design, the positioning area has multiple parallel and spaced grooves, each groove containing a guide rail for connecting the alignment post.

[0011] In one possible design, the alignment post includes a sliding plate, a second locking screw, and a post body; The sliding mechanism is mounted on the guide rail. The second locking screw has two opposing ends, one end of which passes through the slide plate and faces the bottom of the groove, and the other end extends out of the groove. The column body is connected to the second locking screw and is located outside the slide groove.

[0012] In one possible design, the end of the column facing the slot is constructed as an inverted triangle, while the end of the column facing away from the slot has a pointer.

[0013] In one possible design, each end of the first plate is provided with a first fixed contact point adjacent to the second plate, and each of the two third plates is provided with a second fixed contact point directly opposite the first fixed contact point. Correspondingly, the first fixed contact point and the second fixed contact point form a contact group. When the contact connector is installed in the slot, the contact group and the printed circuit board mounting hole on the contact connector are on the same straight line.

[0014] Secondly, the present invention provides an installation and testing apparatus for contact connectors, including the aforementioned clamp for contact connectors.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: Ensuring precise alignment of the connector signal pins and centering the mounting holes on the printed circuit board with the screws after assembly improves the alignment accuracy between the connector screws and the mounting holes, while also ensuring precise alignment between the connector signal pins and the contact pads on the printed circuit board. This significantly improves the link's RF performance, reduces signal transmission loss and reflection during RF transmission, ensures signal transmission quality, and greatly enhances the reliability of electronic products.

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0022] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be apparent to those skilled in the art that these specific details are not necessary to practice the invention. In other embodiments, well-known structures, circuits, materials, or methods have not been specifically described in order to avoid obscuring the invention.

[0023] Throughout this specification, references to "an embodiment," "an example," or "an example" mean that a particular feature, structure, or characteristic described in connection with that embodiment or example is included in at least one embodiment of the invention. Therefore, the phrases "an embodiment," "an example," "an example," or "an example" appearing in various places throughout the specification do not necessarily refer to the same embodiment or example. Furthermore, specific features, structures, or characteristics can be combined in one or more embodiments or examples in any suitable combination and / or sub-combination. Moreover, those skilled in the art will understand that the illustrations provided herein are for illustrative purposes and are not necessarily drawn to scale. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] In the description of this invention, the terms "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "high", "low", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this invention.

[0025] Example: For existing contact connectors, since the diameter of the printed circuit board mounting hole is much larger than the diameter of the mounting screw, when the mounting screw is inserted into the printed circuit board mounting hole, the screw cannot be guaranteed to be centered in the printed circuit board mounting hole. This causes the contact connector signal pin to be offset from the surface mount pad of the printed circuit board. The larger the offset, the worse the link RF performance, and the greater the impact of insertion loss on high frequency signal quality.

[0026] Furthermore, in the existing contact connector assembly, misalignment and displacement of the plug and socket connectors can occur during use, which can easily lead to impedance abrupt changes in the connection area. This results in increased signal transmission loss and reflection, reducing the target transmission quality of radio frequency signals.

[0027] In response, this embodiment provides a clamp for a contact connector that ensures the precise alignment of the contact connector signal pins and the center position of the mounting holes on the printed circuit board after installation. This improves the alignment accuracy between the connector screws and the mounting holes on the printed circuit board, while also ensuring the precise alignment between the contact connector signal pins and the contact pads on the printed circuit board. This significantly improves the link's radio frequency performance, reduces signal transmission loss and reflection during radio frequency transmission, ensures signal transmission quality, and greatly enhances the reliability of electronic products.

[0028] Specifically: such as Figures 1-4 As shown, in a first aspect, the present invention provides a clamp for a contact connector, comprising: The fixture body 100 has a slot 300 for connecting a contact connector; Alignment posts 200 are slidably disposed on the fixture body 100. Alignment posts 200 are used for fixing and positioning the contact connector.

[0029] In the aforementioned contact connector clamp, a slot 300 is formed by the clamp body 100. The contact connector is inserted into the slot 300 and connected to the clamp body 100. It is easy to understand that the clamp body 100 can be constructed in any suitable shape, and the shape of the slot 300 is adapted to the contact connector to improve the effect of fixing the contact connector.

[0030] Meanwhile, the fixture body 100 is provided with an alignment post 200. The alignment post 200 can slide along the fixture body 100 and adjust its position so that the alignment post 200 is aligned with the pads on the contact connector, thereby positioning the contact connector. After the alignment post 200 is aligned with the pads, the contact connector is fixed by the alignment post 200 cooperating with the fixture body 100.

[0031] In addition, for contact connectors, see [link to relevant documentation]. Figure 1 Each end of the device has a printed circuit board mounting hole, and multiple pads are provided between the two printed circuit board mounting holes. Correspondingly, the alignment post 200 has multiple pads, each corresponding to one of the pads.

[0032] It is worth noting that as the number of solder pads on the contact connector increases, the size of the contact connector also changes; for example, the more solder pads, the larger the size of the contact connector. To address this, in one possible implementation, the fixture body 100 is provided with a telescopic structure 400 for adjusting the size of the slot 300. Based on the above design, the size of the fixture body 100 is adjusted via the telescopic structure 400 to adapt the size of the slot 300 to the corresponding contact connector. This helps to expand the application range and versatility of the contact connector fixture, reduces the number of fixtures used and produced for different products, saves manufacturing costs for normal products, and greatly improves the reliability of electronic products.

[0033] In one possible implementation, the fixture body 100 includes a first plate 101, a second plate 102, and a third plate 103; The first plate 101 is connected to a second plate 102 at each end. Correspondingly, there are two second plates 102 arranged opposite to each other. Each second plate 102 is connected at both ends to the end of the first plate 101 and the third plate 103 respectively, so that the first plate 101 and the third plate 103 are opposite and parallel. Accordingly, there are two third plates 103. Accordingly, the first plate 101, the second plate 102 and the third plate 103 form the slot 300; the first plate 101 and the second plate 102 are respectively provided with the telescopic structure 400.

[0034] Based on the above design scheme, the first plate 101, the second plate 102 and the third plate 103 cooperate with each other to form a ring structure with a notch. While forming the slot 300 and ensuring the effect of fixing the contact connector, the weight of the fixture body 100 is reduced as much as possible, and the operating angle is increased by the notch to facilitate adjustment.

[0035] It is worth noting that the first plate 101 and the second plate 102 are respectively provided with the telescopic structure 400. The first plate 101 and the second plate 102 are oriented in different directions, which increases the adjustment direction and the adjustment range of the size of the slot 300, so as to be used for different types of contact connectors.

[0036] Optionally, such as Figure 1 and Figure 2 As shown, the second plate 102 is perpendicular to the first plate 101 and the third plate 103, and the first plate 101 and the third plate 103 are parallel to each other. Based on this, a frame-shaped clamp body 100 and a square slot 300 are formed. It is easy to understand that the clamp body 100 and the slot 300 can also be constructed into any other suitable shape.

[0037] In one possible implementation, the telescopic structure 400 includes a telescopic shaft 410 and a first locking screw 420; The telescopic shaft 410 includes a sleeve 411 that passes through the plate body and a sub-sleeve 412 that is slidably disposed on the sleeve 411. At least one sub-sleeve 412 is provided. When multiple sub-sleeves 412 are provided, the sub-sleeves 412 are inserted sequentially from the inside to the outside. The first locking screw 420 is disposed on the plate and offset from the sleeve 411. The first locking screw 420 is used to fix the sub-sleeve 412. Accordingly, the plate body includes a first plate body 101 and a second plate body 102.

[0038] Based on the above design, the telescopic structure 400 extends and retracts via the telescopic shaft 410, thereby adjusting the dimensions of the clamp body 100 and the slot 300. For example, Figure 1 As shown, the length of the first plate 101 changes vertically by extending and retracting the telescopic shaft 410; similarly, the length of the second plate 102 changes horizontally by extending and retracting the telescopic shaft 410. After the length has extended or retracted to the desired value, the first locking screw 420 is tightened to fix the telescopic shaft 410, thereby achieving fixation; conversely, the first locking screw 420 is loosened to allow the telescopic shaft 410 to extend and retract again.

[0039] The telescopic shaft 410 is connected to the plate body via a sleeve 411. The sub-sleeve 412 can slide relative to the sleeve 411. Accordingly, when the sub-sleeve 412 slides inward toward the sleeve 411, the length of the telescopic shaft 410 decreases; conversely, when the sub-sleeve 412 slides outward toward the sleeve 411, the length of the telescopic shaft 410 increases. The first locking screw 420 is offset from the sleeve 411 and positioned in the direction of the sliding of the sub-sleeve 412. When the sub-sleeve 412 slides out of the sleeve 411, the first locking screw 420 can be tightened as needed until it abuts against the sub-sleeve 412, thus achieving fixation. It is easy to understand that when there are multiple sub-sleeves 412, there is at least one first locking screw 420 to ensure at least one fixing point.

[0040] It is easy to understand that the telescopic structure 400 can be flexibly positioned for the plate. Taking the first plate 101 as an example, the telescopic structure 400 can be located inside the first plate 101 to divide the first plate 101 into at least two adjacent sub-parts, which are connected by the telescopic structure 400; or, the telescopic structure 400 can be located at the end of the plate so that the first plate 101 is connected to the adjacent second plate 102 by the telescopic structure 400.

[0041] Optionally, such as Figure 1As shown, the first plate 101 is provided with two spaced telescopic structures 400, and the part of the first plate 101 located between the two telescopic structures 400 is constructed as a positioning area for connecting the alignment post 200.

[0042] Based on the above design, considering that the first plate 101 corresponds to the length direction of the contact connector, resulting in a relatively large length, multiple telescopic structures 400 are provided to increase the adjustment range and flexibility of the first plate 101. Simultaneously, considering the placement of the alignment posts 200, the telescopic structures 400 are used as boundaries to divide the area, avoiding interference between different areas.

[0043] In one possible implementation, the positioning area is provided with multiple parallel and spaced grooves, each groove containing a guide rail 106 for connecting the alignment post 200. Based on the above design, the grooves and guide rails 106 cooperate to guide the sliding direction of the alignment post 200, enabling it to move along the designed direction. Furthermore, this helps reduce the difficulty of moving the alignment post 200, making its movement smoother and more convenient.

[0044] In one possible implementation, the alignment post 200 includes a sliding plate 201, a second locking screw 202, and a post body 203; The skateboard 201 is slidably mounted on the guide rail 106; The second locking screw 202 has two opposing ends, one end of which passes through the slide plate 201 and faces the bottom of the groove, and the other end extends out of the groove. The column body 203 is connected to the second locking screw 202 and is located outside the slide groove.

[0045] Based on the above design, when the second locking screw 202 is turned, and it disengages from the bottom of the slide groove, the force between the alignment post 200 and the slide groove disappears. The slide plate 201 can then move along the guide rail 106, and the post body 203 follows suit until it reaches the desired position. At this point, the second locking screw 202 is turned to press against the bottom of the slide groove, using pressure to fix the position of the alignment post 200 and ensure that the post body 203 is aligned with the pad.

[0046] Therefore, the operator can control the sliding of the alignment post 200 by turning the second locking screw 202. The operation is simple and easy to promote and master.

[0047] Accordingly, the column body 203 can be constructed into any suitable shape. Preferably, such as Figure 1As shown, the end of the column body 203 facing the slot 300 is constructed in an inverted triangle shape, while the end of the column body 203 facing away from the slot 300 has a pointer. Based on the above design, the inverted triangle reduces the contact area and increases the pressure exerted by the column body 203 on the contact connector, thus ensuring the fixing effect of the alignment column 200. The pointer is for the operator to use to confirm the position of the alignment column 200, especially when the clamp body 100 and the contact connector are obstructed, to facilitate accurate alignment.

[0048] In one possible implementation, the first plate 101 has a first fixed contact point 104 at each end that is adjacent to the second plate 102, and the two third plates 103 have a second fixed contact point 105 that is directly opposite the first fixed contact point 104. Correspondingly, the first fixed contact point 104 and the second fixed contact point 105 form a contact group. When the contact connector is installed in the slot 300, the contact group and the printed circuit board mounting hole on the contact connector are on the same straight line.

[0049] Based on the above design scheme, the two contact groups cooperate with each other to achieve a stable connection between the fixture body 100 and the contact connector; at the same time, the risk of loosening is eliminated and disturbances caused by vibration are avoided, so as to improve the connection reliability between the fixture body 100 and the contact connector.

[0050] In summary, the contact connector fixture can be used for the installation or testing of contact connectors, has a wide range of applications, and helps to improve the market competitiveness of the contact connector fixture. Furthermore, the use of the contact connector fixture includes the following steps: S10: Adjust the size of the fixture body 100 based on the size of the contact connector until the size of the slot 300 is larger than the size of the contact connector; S20: The contact connector is installed into the slot 300, the fixed contact point in the contact group abuts against the contact connector, and the fixed contact point and the printed circuit board mounting hole are on the same straight line; S30: Move one of the alignment posts 200 until the alignment post 200 is aligned with the pad on the contact connector; repeat S30 until all the alignment posts 200 are aligned with a pad respectively; S40: Adjust the size of the clamp body 100 based on the telescopic structure 400 until the size of the slot 300 is adapted to the size of the contact connector; fix the size of the clamp body 100 by means of the telescopic structure 400.

[0051] Secondly, the present invention provides an installation and testing apparatus for contact connectors, including the aforementioned contact connector fixture. Based on this, the installation and testing apparatus for contact connectors can further include other suitable functional modules, resulting in richer functionality to meet different operational requirements and improved practicality. Furthermore, it is readily understood that these functional modules can be selected from any suitable existing equipment, offering a wide range of choices.

[0052] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
