Description

TECHNICAL FIELD

[0001] The present application relates to the field of connectors, in particular to a variable height connector. BACKGROUND

[0002] In the field of electronic devices, connectors play a crucial role as key components, and their proper functioning is essential for the normal operation of the devices. With the continuous development and diversification of electronic devices, there is an increasing demand for the performance and adaptability of connectors. The rational design of connector height is directly related to the assembly efficiency and compatibility of the devices, and the demand for connector height varies in different application scenarios. This has prompted the industry to continuously explore and innovate to meet the growing demand for diversification.

[0003] Currently, there are several solutions in the industry to solve the problem of connector height adaptation. The use of gasket stacking is a way to adjust the height by adding or removing gaskets, which is relatively low in cost. The use of a threaded adjustment mechanism can achieve continuous height adjustment. Developing multiple models of connectors, each with a dedicated connector for each height requirement, has strong adaptability. In addition, to address vibration conditions, the conventional solution is to add rubber buffer pads to alleviate the impact.

[0004] However, the existing technology has obvious defects. Traditional connectors generally adopt a single fixed height design, and when different devices have different connection height requirements, multiple connectors of different specifications need to be developed and produced, increasing the development cost and the complexity of production management. The gasket stacking solution is cumbersome to operate, and parts are easily lost during disassembly and maintenance; the threaded adjustment mechanism is relatively large in size and has poor anti-vibration performance, and is prone to looseness in a vibrating environment; developing multiple models of connectors can dramatically increase inventory and management costs. Adding rubber buffer pads to alleviate the impact can cause unstable contact resistance of the connector, affecting the reliability of signal transmission. SUMMARY

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be further described below with reference to the drawings. Figures 1-5 The present application is further described in detail.

[0041] The technical solutions in the embodiments of the present application will be further described below with reference to the drawings.

[0042] The present application mainly adopts the scheme of upper and lower main body sliding cooperation and multi-gear locking, which achieves the effects of realizing variable height of the connector and precise positioning, strong anti-vibration. The present application is further described in detail as follows.

[0043] Embodiment 1

[0044] Please refer to Figures 1-7 The variable height connector provided by the embodiments of the present application includes a lower connector main body 1, an upper connector main body 2, at least one elastic element 3 and a height adjustment locking mechanism 4. The upper connector main body 2 can slide along the vertical direction relative to the lower connector main body 1. The elastic element 3 is arranged between the upper connector main body 2 and the lower connector main body 1, which can provide elastic force to make the two bodies move away from each other. The height adjustment locking mechanism 4 can lock the relative position of the upper connector main body 2 and the lower connector main body 1 at a preset height, which achieves the beneficial effects of realizing multi-gear height adjustment and reliable locking of the connector. This is because the elastic force provided by the elastic element 3 makes the upper connector main body 2 have a tendency to move upward, and the height adjustment locking mechanism 4 limits the movement of the upper connector main body 2 by the protruding end 411 of the elastic arm 41 being engaged with the gear recess 11, thereby realizing height locking.

[0045] The technical solution can be applied to narrow shell assembly. When the distance between the upper and lower plates in the shell is limited, or there are other high parts on the plate that block the assembly and make it inconvenient to assemble, the height of the connector can be lowered first, and then returned and positioned to the required height after the mechanism plate is assembled. It can be directly taken out for maintenance or inspection, and it is convenient to disassemble. In addition, by designing multiple different gears, different gears correspond to different product total heights, so that one product can replace multiple connectors with different plate heights, greatly saving development investment costs.

[0046] Specifically, the upper connector body 2 is the upper half structure of the connector (as shown in Figure 3 ). The upper connector body 2 is usually made of insulating materials such as plastic to ensure its insulation performance and certain mechanical strength. Its shape is generally square or rectangular to adapt to the common electronic equipment installation requirements. The replaceable features of the upper connector body 2 can be different sizes to meet the space requirements of different devices, or use different plastic materials to improve their high temperature resistance, chemical corrosion resistance and other properties. The lower connector body 1 is the lower half structure of the connector (as shown in Figure 2 ), which cooperates with the upper connector body 2. The lower connector body 1 is also made of insulating materials such as plastic, and its shape is adapted to the upper connector body 2. Its replaceable features can also be different sizes and materials, and the outer side wall of the lower connector body 1 is provided with a plurality of gear grooves 11 along the sliding direction. These gear grooves 11 can be rectangular, trapezoidal, etc., which can be engaged with the protruding end 411 of the elastic arm 41 to achieve height locking. Please refer to Figure 1 and Figure 2 , four support seats 14 are added to the bottom of the lower connector body 1 to effectively prevent the product from turning over or tilting forward and backward during use. The upper connector body 2 can slide vertically relative to the lower connector body 1. This sliding fit allows the connector to adjust the height.

[0047] Specifically, the elastic element 3 includes springs and the like. The spring is generally made of metal materials such as stainless steel to ensure its elasticity and corrosion resistance. The shape of the spring is usually spiral, one end of which is connected with the upper connector body 2, and the other end is connected with the lower connector body 1. The replaceable features of the spring can be different elastic coefficients to adapt to different use scenarios, or use other materials with elasticity such as rubber. In order to ensure the reliability of the spring in operation and prevent it from bending or jumping out to cause failure when compressed, the present application is specially designed: please refer to Figure 5A plastic positioning column 15 is designed in the lower connector body 1, and a circular plastic groove 25 is designed on the upper connector body 2. The elastic element 3 is arranged between the upper connector body 2 and the lower connector body 1, and when the height of the connector changes, the spring will be compressed or stretched, thereby providing elastic force to move the two away from each other.

[0048] Specifically, please refer to Figures 3-5 The height adjustment locking mechanism 4 includes at least one elastic arm 41 with a protruding end 411. The elastic arm 41 is usually made of sheet metal, such as copper alloy, etc., and has a certain elasticity and strength. The shape of the elastic arm 41 can be arc-shaped, linear, etc., and the protruding end 411 is generally circular or square-shaped, so as to better engage with the gear groove 11. The replaceable features of the elastic arm 41 can be different shapes and materials to change its elasticity and engagement reliability. The elastic arm 41 is arranged on the other of the upper connector body 2 and the lower connector body 1, and the protruding end 411 is configured to selectively engage with any one of the plurality of gear grooves 11. By pressing the elastic arm 41, the protruding end 411 can be disengaged from the gear groove 11, and the locking is released. When the target gear is reached, the elastic arm 41 is released, and the protruding end 411 automatically pops back and engages into the corresponding gear groove 11, locking the relative position of the upper connector body 2 and the lower connector body 1 at the preset height. After locking, the upper and lower connectors form an integral whole and no longer float, ensuring the reliability when mutually plugging with the opposite plug end. This gear locking structure also ensures that the terminal can maintain reliable connection in a vibrating environment, solving the problem of unstable contact resistance caused by adding a buffer pad to resist vibration in the prior art.

[0049] In order to further improve the reliability, in this application, a first reinforcing rib 26 is designed on the inner side wall of the spring of the upper connector body 2, which is used to enhance the structural strength of the spring cavity, and can effectively prevent the elastic arm 41 from being concave inward, so that it always maintains the tendency to expand outward. In addition, a second reinforcing rib 42 is also added to the upper part of the elastic arm 41 to ensure the structural strength of the elastic arm itself, so that it is not easy to deform. Correspondingly, please refer to Figure 2 An avoidance groove 16 is opened on the lower connector body 1 to accommodate the second reinforcing rib 42 when assembling and sliding.

[0050] Specifically, the connector also has a guiding mechanism for guiding the linear sliding of the upper connector body 2 relative to the lower connector body 1, which makes the sliding of the upper connector body 2 more stable and accurate, avoiding shaking and deviation.

[0051] Specifically, the guide mechanism includes at least one slide rail 21 and at least one slide rail groove 12. The slide rail 21 is generally made of metal or plastic, and has a long strip shape with a smooth surface to reduce friction when sliding. The replaceable features of the slide rail 21 can be different lengths and cross-sectional shapes to adapt to different usage requirements. The slide rail groove 12 is matched with the slide rail 21, and its inner wall is also relatively smooth. The replaceable features of the slide rail groove 12 can also be different sizes and shapes. The slide rail 21 is arranged on one of the upper connector body 2 and the lower connector body 1, and the slide rail groove 12 is arranged on the other one, which are in sliding fit to ensure the linear precision of the upper connector body 2 during sliding.

[0052] Specifically, the four corners of the upper connector body 2 are each provided with a slide rail 21, and the lower connector body 1 is internally provided with four slide rail grooves 12 corresponding thereto. This design makes the upper connector body 2 more stable during sliding, effectively preventing side turning or shaking, and further improving the precision and reliability of sliding.

[0053] Specifically, a plurality of gear recesses 11 are arranged on the outer side wall of the lower connector body 1, and at least one elastic arm 41 is arranged on the upper connector body 2. The protruding end 411 of the elastic arm 41 can be pressed to disengage from the gear recess 11 to release the locking. This arrangement makes the operation more convenient, and the user can easily adjust and lock the height by pressing the elastic arm 41.

[0054] Specifically, please refer to Figure 5 , the first conductive terminal 13 is arranged in the lower connector body 1, and the second conductive terminal 22 is arranged in the upper connector body 2. At all lockable preset heights (as shown in Figure 6 、 Figure 7 ), the first conductive terminal 13 and the second conductive terminal 22 are in electrical contact. This ensures the reliability of signal transmission during height adjustment of the connector, and prevents poor contact due to height changes.

[0055] Specifically, the first conductive terminal 13 includes a first contact spring 131, which is generally made of a material with good conductivity such as copper alloy, and has a sheet shape with a certain elasticity. The replaceable features of the first contact spring 131 can be different thicknesses and elastic coefficients to change its contact performance. One end of the second conductive terminal 22 is formed with a first pin 221 matched with the first contact spring 131. The first pin 221 is usually cylindrical and made of metal. At all lockable preset heights, the first pin 221 can be in contact with the first contact spring 131 to ensure the stability of the electrical connection.

[0056] The principle of the embodiment is that the variable height connector provides elastic force through the elastic element 3, so that the upper connector body 2 has a tendency to move upward, and the elastic arm 41 protruding end 411 of the height adjustment locking mechanism 4 is clamped with the gear recess 11, so as to realize the multi-gear adjustment and locking of the height. The guide mechanism ensures the linear precision and stability of the sliding of the upper connector body 2, and prevents side turning and shaking. At the same time, the design of the conductive terminal ensures reliable electrical contact at all height gears. Compared with the prior art, it solves the problems of fixed height, inconvenient adjustment and other problems of traditional connectors, realizes single product instead of multiple products, saves cost, and facilitates assembly and maintenance.

[0057] Embodiment 2

[0058] Please refer to Figure 8 and Figure 9 The difference between the embodiment and the above-mentioned embodiment is that the other end of the second conductive terminal 22 is formed with a second contact spring 222 matched with the second pin of the external terminal; the variable height connector further comprises a clamping force control mechanism 5, which is used to control the size of the clamping force between the second contact spring 222 and the second pin, so as to keep it within a predetermined range.

[0059] Specifically, the second contact spring 222 is generally made of copper alloy or other materials with good conductive performance and certain elasticity, and its shape can be ring-shaped or arc-shaped, so as to better cooperate with the second pin. The replaceable features of the second contact spring 222 can be different shapes and elastic coefficients to adapt to different clamping force requirements. The second pin is usually cylindrical and made of metal, which is used to cooperate with the second contact spring 222 to realize electrical connection.

[0060] Specifically, the upper connector body 2 is provided with a containing groove 23 for accommodating the second conductive terminal 22. The shape of the containing groove 23 is generally matched with the second conductive terminal 22, and is usually square or circular. The inner side wall of the containing groove 23 is provided with an expansion groove 24, which provides a sliding space for the sliding frame 51 of the clamping force control mechanism 5.

[0061] Specifically, the clamping force control mechanism 5 includes a sliding frame 51, a strain gauge 52 and a piezoelectric actuator 53. The sliding frame 51 is generally made of plastic or metal, and its inner diameter gradually increases along the sliding direction, and is sleeved on the second contact spring 222. The sliding frame 51 is made of high-strength insulating material (such as hard plastic). The strain gauge 52 is arranged between the inner wall of the sliding frame 51 and the outer wall of the second contact spring 222, for detecting the pressure between the two, so as to perceive the size of the clamping force between the second contact spring 222 and the second pin. The piezoelectric actuator 53 is used to drive the sliding frame 51 to move in response to the result perceived by the strain gauge 52. The piezoelectric actuator 53 is generally made of piezoelectric ceramic or the like, and has the characteristics of fast response speed and high precision. Its replaceable features can be different driving capacity and response time.

[0062] Specifically, the clamping force control mechanism 5 further includes a guide sleeve 54 and a guide shaft 55. The guide sleeve 54 is fixed in the telescopic groove 24, and the guide shaft 55 is fixed on the sliding frame 51 and slidingly arranged in the guide sleeve 54. The sliding direction of the guide shaft 55 is parallel to the moving direction of the sliding frame 51. The guide sleeve 54 and the guide shaft 55 are generally made of metal or plastic. The inner diameter of the guide sleeve 54 is matched with the outer diameter of the guide shaft 55, so as to ensure smooth sliding of the guide shaft 55. The arrangement of the guide sleeve 54 and the guide shaft 55 makes the movement of the sliding frame 51 more stable and accurate, and improves the precision of clamping force control.

[0063] In order to realize intelligent control of the clamping force control mechanism 5, a micro control circuit (not shown) is further arranged on the connector. The control circuit can obtain working power through specific pins in the first conductive terminal 13 and the second conductive terminal 22 of the connector, or through a specially designed power supply pin, and provide the strain gauge 52 and the piezoelectric actuator 53 with required electric energy. In addition, in order to facilitate user operation, a clamping button and a releasing button can be arranged on the outside of the upper connector body 2, and both are electrically connected with the micro control circuit. When it is needed to plug or separate the second pin of the external terminal, the user can press the releasing button. At this time, the control circuit will issue an instruction to the piezoelectric actuator 53 to drive the sliding frame 51 to move in the direction of opening the second contact spring 222, so as to completely release the clamping force and facilitate plugging and unplugging operation. When the second pin is inserted in place, the user presses the clamping button, and the control circuit starts the automatic clamping program: the piezoelectric actuator 53 drives the sliding frame 51 to move in the direction of tightening the second contact spring 222, and the strain gauge 52 monitors the clamping force in real time and feeds back through the control circuit. When the clamping force reaches the preset ideal range, the control circuit stops driving the piezoelectric actuator 53, and the reliable clamping is completed.

[0064] The implementation principle of the embodiment is that the variable height connector adds a clamping force control mechanism 5 on the basis of the above embodiment. The strain gauge 52 detects the clamping force between the second contact spring 222 and the second pin, and when the clamping force is not within the preset range, the piezoelectric actuator 53 drives the sliding frame 51 to move, changes the tightening or opening degree of the second contact spring 222, thereby adjusting the clamping force to keep it within the preset range. This design improves the stability and reliability of the connector in connecting with external terminals, reduces the problem of poor contact caused by unstable clamping force, and further improves the quality of signal transmission. Compared with the prior art, it solves the problem that the clamping force of the traditional connector is difficult to control when connecting with external terminals, and improves the overall performance of the connector.

[0065] The specific embodiments of the application described above do not constitute a limitation on the protection scope of the application. Any various other corresponding changes and modifications made according to the technical concept of the application should be included in the protection scope of the application.
