Technical Field
[0001] The utility model relates to the technical field of connection equipment, in particular to an electronic connector with replaceable contacts. Background Art
[0002] Electronic connectors with replaceable contacts have a wide range of applications, covering multiple industries such as communications equipment, consumer electronics, automotive electronics, industrial control and medical equipment. The development prospects of this type of connector are very broad, especially driven by the rapid development of new energy vehicles and smart devices, the demand for high-speed and high-reliability connectors continues to grow. Electronic connectors with replaceable contacts will occupy a more important position in the future electronics industry due to their wide application prospects and potential for technological innovation. Enterprises in the industry should continue to pay attention to technological development trends and changes in market demand to seize future development opportunities.
[0003] In the prior art, replacing the contacts of electronic connectors is a delicate and complicated maintenance work, which usually requires separating the electronic connector from the device. During the replacement process, the maintenance personnel must first disassemble the connector, which often involves carefully loosening or cutting the adhesive that fixes the connector. Since most electronic connectors and devices are connected with strong adhesives to ensure firmness, this adhesive connection makes disassembly extremely difficult during multiple repairs. The difficult disassembly process not only increases the maintenance time and labor intensity, but also causes damage to the contacts and pins on the device due to improper operation. Once these tiny but critical components are damaged, they will affect the electrical connection quality of the device, thereby reducing the overall performance and service life of the device. In addition, frequent replacement and repair work also causes additional wear or damage to the circuit boards and other sensitive components inside the device, further shortening the effective use cycle of the equipment. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes an electronic connector with replaceable contacts.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an electronic connector with replaceable contacts, comprising a rectangular connector contact, a pin row is fixed on the inner wall of the rectangular connector contact, a back plate is fixed on the back of the rectangular connector contact, a sinking square groove is provided on the top of the back plate, a bottom sinking ring groove is provided on the bottom of the back plate, a friction-increasing ring is fixed on the inner wall of the bottom sinking ring groove, a sliding inner cylinder is fixed on the inner wall of the sinking square groove, a residual ring column is slidably connected to the inner wall of the sliding inner cylinder, a limiting end is fixed on one end of the residual ring column, and the top end of the limiting end is set as a bevel. The other end of the residual ring column is fixed with a fixed bottom plate, the inner wall of the residual ring column is provided with a threaded groove, the inner wall of the residual ring column is threadedly connected with a screw, and one end of the limit end is slidably connected with the surface of the friction-increasing ring. In the prior art, the replacement of the contacts of the electronic connector is a delicate and complicated maintenance work, which usually requires the electronic connector to be separated from the device before it can be carried out. During the replacement process, the maintenance personnel must first disassemble the connector, which often involves carefully untying or cutting off the adhesive that fixes the connector. Since most electronic connectors have multiple connections with the device, it is difficult to remove the connector from the device. Strong adhesive is used to ensure firmness. This adhesive connection makes disassembly extremely difficult during multiple repairs. The difficult disassembly process not only increases the maintenance time and labor intensity, but also causes damage to the contacts and pins on the equipment due to improper operation. Once these tiny but critical components are damaged, they will affect the electrical connection quality of the equipment, thereby reducing the overall performance and service life of the equipment. In addition, frequent replacement and repair work also causes additional wear or damage to the circuit board and other sensitive components inside the equipment, further shortening the effective use cycle of the equipment. In response to such problems, the utility model solves the problem by installing a residual ring column. When the staff needs to fix the component, the fixed base plate is first fixed to the equipment, and then the sliding inner cylinder is inserted into the residual ring column, and then the screw is screwed into the residual ring column, so that the residual ring column is squeezed and dispersed around, so that the residual ring column pressure fixes the sliding inner cylinder, and at the same time, the limit end prevents the sliding inner cylinder from being pressed away, so that the component is fixed. When the staff needs to disassemble the rectangular connector contact, the screw is screwed out to reset the residual ring column, which is convenient for removing the component, thereby improving the replacement efficiency of the electronic connector contact and achieving the effect of improving user experience.
[0006] Preferably, a cross reinforcing rib is fixed to the inner wall of the countersunk square groove, and one end of the cross reinforcing rib is fixed to the circumferential surface of the sliding inner cylinder. In the prior art, when installing the rectangular connector contacts, it is necessary to ensure that the pressing between the device and the back plate is tight to ensure good electrical connection and mechanical stability. However, in order to achieve such a tight pressing, the operator often needs to apply a large force to ensure the combination between the two. This excessive pressing force sometimes exceeds the bearing range of the back plate material, causing the back plate to deform. Once the back plate is deformed, the fixing structure thereon cannot be correctly aligned with the connector contacts, thereby affecting the fixing effect of the entire connector system, and the deformation of the back plate. Not only will it reduce the fixing effect of the connector, it will also cause poor contact of the connector, thereby affecting the normal operation of the equipment. For example, if the back plate is bent or twisted, the connector contacts will not be able to withstand pressure evenly, causing unstable contact of some contacts, and even circuit breakage or increased resistance. In addition, the deformed back plate will also cause fatigue damage during long-term operation, shortening the service life of the equipment. To address such problems, the utility model adopts the method of installing cross stiffeners to solve them. The reinforcement of the cross stiffeners and the elastic deformation and buffering of their materials can prevent the back plate from undergoing rigid deformation, thereby ensuring the service life of the components and achieving the effect of increasing the service life of the equipment.
[0007] Preferably, an insert is fixed at the bottom of the fixed base plate, and the side of the insert is slidably connected to the inner wall of the countersunk groove. In the prior art, in a production environment, especially in those occasions with narrow working space, workers face many challenges when assembling equipment. For example, when installing rectangular connector contacts, the limited operating space makes it difficult for workers to perform precise operations. In this case, alignment deviations are likely to occur between the components and the connector contacts, resulting in incorrect matching. Incorrect installation may lead to equipment performance degradation or failure. In addition, the installation of the residual ring column is also affected by space limitations. Due to the narrow space, workers may encounter difficulties when trying to insert the residual ring column into the sliding inner cylinder. This operation usually requires a high degree of precision and patience, because any slight error may result in the residual ring column failing to be inserted correctly, or causing damage to the component during the insertion process. Such problems not only slow down the assembly speed, but also increase the scrap rate in the production process, thereby reducing the overall production efficiency. In response to such problems, the utility model solves them by installing inserts, thereby achieving the effect of assisting workers in judging the accuracy of the installation through inserts, facilitating workers to assemble their components, and achieving the effect of improving production efficiency.
[0008] Preferably, a bottom support piece is fixed to the bottom of the back plate, and a bottom embedding groove is provided at the bottom of the bottom support piece to improve the fixing effect.
[0009] Preferably, one end of the back plate is configured as a chamfered edge to prevent scratches on other components and increase the service life of the equipment.
[0010] Preferably, the front side of the rectangular connector contact is provided with side slots to improve heat dissipation efficiency.
[0011] Preferably, a weight-reducing and reinforcing rib groove is provided on the front side of the rectangular connector contact to reduce the deadweight of the device.

[0013] 1. In the prior art, replacing the contacts of electronic connectors is a delicate and complex maintenance work, which usually requires separating the electronic connector from the device. During the replacement process, the maintenance personnel must first disassemble the connector, which often involves carefully loosening or cutting off the adhesive that fixes the connector. Since most electronic connectors and devices are connected with strong adhesives to ensure firmness, this adhesive connection makes disassembly extremely difficult during multiple repairs. The difficult disassembly process not only increases the maintenance time and labor intensity, but also causes damage to the contacts and pins on the device due to improper operation. Once these tiny but critical components are damaged, they will affect the electrical connection quality of the device, thereby reducing the overall performance and use of the device. Lifespan. In addition, frequent replacement and repair work also causes additional wear or damage to the circuit boards and other sensitive components inside the equipment, further shortening the effective use cycle of the equipment. To address such problems, the utility model solves the problem by installing a residual ring column. When the staff needs to fix the component, they first fix the fixed base plate to the equipment, then insert the sliding inner cylinder into the residual ring column, and then screw the screw into the residual ring column, so that the residual ring column is squeezed and dispersed around, so that the residual ring column pressure fixes the sliding inner cylinder, and at the same time, the limit end prevents the sliding inner cylinder from being pressed away, so that the component is fixed. When the staff needs to disassemble the rectangular connector contacts, they screw out the screw to reset the residual ring column, which is convenient for removing the component, thereby improving the replacement efficiency of the electronic connector contacts and achieving the effect of improving user experience.
[0014] 2. In the prior art, when installing rectangular connector contacts, it is necessary to ensure that the pressing between the device and the back plate is tight to ensure good electrical connection and mechanical stability. However, in order to achieve such tight pressing, the operator often needs to apply a large force to ensure the combination between the two. This excessive pressing force sometimes exceeds the bearing range of the back plate material, causing the back plate to deform. Once the back plate is deformed, the fixing structure thereon cannot be properly aligned with the connector contacts, thereby affecting the fixing effect of the entire connector system. The deformation of the back plate not only reduces the fixing effect of the connector, but also causes poor contact of the connector, thereby affecting the normal operation of the device. For example, if the back plate is bent or twisted, the connector contacts cannot withstand pressure evenly, causing unstable contact of some contacts, and even circuit breakage or increased resistance. In addition, the deformed back plate also causes fatigue damage in long-term operation, shortening the service life of the equipment. In response to such problems, the utility model solves the problem by installing cross stiffeners, which prevents the back plate from rigid deformation through the reinforcement of the cross stiffeners and the elastic deformation and buffering of its material, thereby ensuring the service life of the components and achieving the effect of improving the service life of the equipment.
[0015] 3. In the prior art, in a production environment, especially in those occasions with narrow working spaces, workers face many challenges when assembling equipment. For example, when installing rectangular connector contacts, the limited operating space makes it difficult for workers to perform precise operations. In this case, alignment deviations are likely to occur between the components and the connector contacts, resulting in incorrect matching.

Such problems not only slow down the assembly speed, but also increase the scrap rate in the production process, thereby reducing the overall production efficiency. In response to such problems, the utility model solves the problem by installing embedded square parts, thereby realizing the use of embedded square parts to assist workers in judging the accuracy of the installation, making it easier for workers to assemble the components, thereby improving production efficiency.

The replacement of the contacts of the electronic connector is a delicate and complicated maintenance work, which usually requires the electronic connector to be separated from the device before it can be carried out. During the replacement process, the maintenance personnel must first disassemble the connector, which often involves carefully untying or cutting off the adhesive that fixes the connector. Since most electronic connectors and devices are connected with strong adhesives to ensure firmness, this adhesive connection makes disassembly extremely difficult during multiple repairs. The difficult disassembly process not only increases the maintenance time and labor intensity, but also causes damage to the contacts and pins on the device due to improper operation. Once these tiny but critical components are damaged, they will affect the electrical connection quality of the device, thereby reducing the overall performance and service life of the device. In addition, frequent replacement and repair work also causes additional wear or damage to the circuit board and other sensitive components inside the device, further shortening the effective use cycle of the equipment. The method of installing the residual ring column 209 is used to solve the problem, realizing that when the worker When the staff needs to fix the component, first fix the fixed bottom plate 205 to the equipment, then insert the sliding inner cylinder 202 into the residual ring column 209, and then screw the screw 204 into the residual ring column 209, so that the residual ring column 209 is squeezed and dispersed around, so that the residual ring column 209 pressure fixes the sliding inner cylinder 202, and at the same time, the limit end 203 prevents the sliding inner cylinder 202 from being pressed away, so that the component is fixed. When the staff needs to disassemble the rectangular connector contact 1, screw out the screw 204 to reset the residual ring column 209, which is convenient for removing the component, thereby improving the replacement efficiency of the electronic connector contact and achieving the effect of improving user experience. A bottom abutment 301 is fixed at the bottom of the back plate 2, and a bottom groove 302 is provided at the bottom of the bottom abutment 301 to improve the fixing effect. One end of the back plate 2 is set as a corner cut edge 4 to prevent scratching other components and improve the service life of the equipment. A side slot hole 401 is provided on the front of the rectangular connector contact 1 to improve the heat dissipation efficiency. A weight-reducing reinforcing groove 402 is provided on the front side of the rectangular connector contact 1 to reduce the weight of the device.
[0028] A cross reinforcing rib 3 is fixed to the inner wall of the countersunk groove 201, and one end of the cross reinforcing rib 3 is fixed to the circumference of the sliding inner cylinder 202. When installing the rectangular connector contact 1, it is necessary to ensure that the pressing between the device and the back plate 2 is tight to ensure good electrical connection and mechanical stability. However, in order to achieve such a tight pressing, the operator often needs to apply a large force to ensure the combination between the two. This excessive pressing force sometimes exceeds the bearing range of the back plate 2 material, causing the back plate 2 to deform. Once the back plate 2 is deformed, the fixing structure thereon cannot be correctly aligned with the connector contact, thereby affecting the fixing effect of the entire connector system. The deformation of the back plate 2 will not only reduce the fixing effect of the connector, but also cause poor contact of the connector, thereby affecting the normal operation of the equipment. For example, if the back plate 2 is bent or twisted, the connector contacts will not be able to withstand pressure evenly, causing unstable contact of some contacts, or even circuit breakage or increased resistance. In addition, the deformed back plate 2 will also cause fatigue damage during long-term operation, shortening the service life of the equipment. This problem is solved by installing cross stiffeners 3. The reinforcement of the cross stiffeners 3 and the elastic deformation and buffering of their materials can prevent the back plate 2 from undergoing rigid deformation, thereby ensuring the service life of the components and achieving the effect of increasing the service life of the equipment. An insert 206 is fixed at the bottom of the fixed base plate 205, and the side of the insert 206 is slidably connected to the inner wall of the countersunk groove 201. In a production environment, especially in those occasions where the working space is small, workers face many challenges when assembling equipment. For example, when installing the rectangular connector contact 1, the limited operating space makes it difficult for workers to perform precise operations. In this case, alignment deviations are likely to occur between the component and the connector contact, resulting in incorrect matching. Wrong installation may lead to equipment performance degradation or failure. In addition, the installation of the residual ring column 209 is also limited by space. Due to the narrow space, the staff will encounter difficulties when trying to insert the residual ring column 209 into the sliding inner cylinder 202. This operation usually requires a high degree of precision and patience, because any slight error will cause the residual ring column 209 to fail to be inserted correctly, or cause component damage during the insertion process. Such problems not only slow down the assembly speed, but also increase the scrap rate in the production process, thereby reducing the overall production efficiency. The problem is solved by installing the insert 206, which assists the staff in judging the accuracy of the installation through the insert 206, making it easier for the staff to assemble it, thereby improving the production efficiency.
[0029] The working principle of the utility model is as follows: when the staff needs to fix the component, first fix the fixed base plate 205 to the equipment, then insert the sliding inner cylinder 202 into the residual ring column 209, and then screw the screw 204 into the residual ring column 209, so that the residual ring column 209 is squeezed and dispersed around, so that the residual ring column 209 presses and fixes the sliding inner cylinder 202, and at the same time the limit end 203 prevents the sliding inner cylinder 202 from being pressed away, so that the component is fixed. When the staff needs to disassemble the rectangular connector contact 1, the screw 204 is screwed out to reset the residual ring column 209, which is convenient for removing the component, thereby improving the replacement efficiency of the electronic connector contacts.
