Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and specifically to a plug-in connector base that prevents the plug core from bending. Background Art

[0002] The plug-in connector is a common type of connector. It realizes the connection of circuits by inserting a plug into a socket. The connector includes components such as a plug, a socket, contact parts, and a housing. The plug is usually a component with pins or pin sockets at one end for insertion into the socket. The socket is a component with holes or hole sockets for receiving the plug and is usually fixed on the device. The contact parts are small metal parts inside the plug and the socket, responsible for the actual electrical connection. The housing is an external structure that protects the internal contact parts from the external environment. The plug-in connector is designed for frequent plugging and unplugging, which is convenient for maintenance and replacement. Among them, the socket with pins is also called the connector base, which is composed of a housing and a plug core installed inside it. Different numbers of pins are distributed in the plug core according to different models and connection circuits. The head of the pin needs to be inserted into the pin socket inside the plug, and the tail of the pin needs to be docked with the pin socket of the power cord plug. The head of the pin usually matches the metal contact part of the pin socket inside the plug to ensure close contact between the two and maintain good electrical connection.

[0003] In the prior art, although the connector base and the plug adopt a plug-and-play connection method, which is convenient for plugging and maintenance, each connector has a certain plug-and-play life. Since the pins on the plug core are in hard contact when inserted into the pin socket, serious wear is likely to occur during continuous plugging and unplugging, resulting in a decrease in the tightness of the contact between the pins and the metal contact parts inside the pin socket after multiple pluggings and unpluggings, thereby affecting the electrical connection of the connector during plugging and easily causing poor contact.

[0004] In view of the above problems, there is an urgent need to innovate and design on the basis of the original plug-in connector base. Summary of the Invention

[0005] The technical solution of the present invention aims at the technical problem that the prior art solution is too single, and provides a solution significantly different from the prior art. Specifically, the purpose of the present invention is to provide a plug-in connector base that prevents the plug core from bending, so as to solve the problem of easy wear of the pins and poor contact after multiple pluggings and unpluggings proposed in the above background art.

[0007] Preferably, the inner wall of the housing fits with the outer wall of the plug core housing, and a clamping block is arranged on the inner wall of the housing, and a groove matching the clamping block is arranged on the outer wall of the plug core housing.

[0008] Preferably, the elastic clamping member is arranged in a discontinuous annular structure, and handles are symmetrically arranged at the bottom of the discontinuous part of the elastic clamping member, and a discontinuous snap ring is arranged on the outer wall of the upper end of the elastic clamping member, and an annular groove matching the discontinuous snap ring is arranged on the inner wall of the lower end of the housing.

[0009] Preferably, the connection assembly includes a limiting block slidably matched with the lower end of the plug pin, a connection column is connected between the top of the limiting block and the bottom of the upper end of the plug pin, limiting columns penetrating above the limiting block are symmetrically arranged at the bottom of the upper end of the plug pin, and a first spring is connected between the top of the lower end of the plug pin and the bottom of the upper end of the plug pin outside the limiting column.

[0010] Preferably, the lower end of the plug pin is arranged in a hollow structure, and a first through hole is arranged on the top of the lower end of the plug pin outside the connection column.

[0011] Preferably, the guiding assembly includes fixed platforms symmetrically arranged on the outer wall of the plug core housing, a fixed cylinder is fixed inside the fixed platform, a piston block slidably matched with it is arranged inside the fixed cylinder, a top column penetrating the top of the fixed cylinder is connected to the top of the piston block, a second through hole is arranged on the top of the fixed cylinder outside the top column, a guiding plate located at the bottom of the upper end of the plug pin is fixed to the top end of the top column, and an auxiliary driving structure is fixed on the top of the fixed platform on one side of the fixed cylinder.

[0012] Preferably, the auxiliary driving structure includes a fixed groove fixed on the fixed platform and on one side of the fixed cylinder, and the fixed groove is communicated with the lower end of the fixed cylinder through a pipeline, second springs are symmetrically fixed on the inner wall of the fixed groove, a piston plate slidably matched with the fixed groove is jointly connected to the ends of the two second springs, and a guiding block is fixed on the outer wall of the piston plate.

[0013] Preferably, a third through hole matching the bottom of the lower end of the pin is correspondingly provided on the alignment plate, and the edges of the alignment plate and the fixed tabletop are located inside the housing.

[0014] Preferably, the fixed groove is arranged in a rectangular structure with an opening facing outward.

[0015] Preferably, inclined surfaces are symmetrically arranged on the guide block in the vertical direction, a rotating roller is arranged at the intersection of the inclined surfaces of the guide block, and a positioning groove matching the inclined surface of the guide block is provided on the inner wall of the housing.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, an elastic clamping member with a special structure is provided. Pull the handle to deform it, and use the discontinuous clamping ring protruding from the outer wall of the upper end of the elastic clamping member to snap into the annular groove on the inner wall of the housing. Release the handle, and the elastic clamping member can be restored to its original shape and clamped inside the housing. At this time, the elastic clamping member can limit the bottom of the ferrule housing, thus completing the assembly of the connector base. No other tools are required, and it is easy to install and disassemble, greatly improving the installation and disassembly efficiency. In the present invention, an alignment assembly is provided, which is triggered by the inclined surface of the guide block after the ferrule housing is pushed into the housing. Through the extrusion and transportation of the oil, the alignment plate is lifted to a suitable position. During the upward movement of the alignment plate, if the upper end of the pin is bent due to other factors such as transportation, the third through hole of the alignment plate can correct the bent position. After correction, the upper end of the pin may not be completely corrected, but the upper part of the upper end of the pin can be corrected within the conical groove at the bottom of the pin connector, ensuring that the upper end of the pin can be inserted into the conical groove during plugging, thus preventing the upper part of the upper end of the pin from bending beyond the conical groove range and being unable to be plugged. In the present invention, the upper end of the pin with a conical structure and the pin connector with a matching conical groove are provided. During the plugging process, under the action of hard contact, the upper end of the pin that has been initially corrected is completely corrected. Secondly, since the top of the upper end of the pin is flat, there is a small reduction in volume due to wear, but the worn shape is still conical. Under the reverse pushing action of the first spring, the upper end of the pin is always in close contact with the inner wall of the conical groove at the bottom of the pin connector. Each upper end of the pin can be adaptively inserted into different depths of the conical groove according to the wear situation, thus ensuring the plugging tightness between the pin connector and the upper end of the pin and avoiding the phenomenon of poor contact due to wear.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 10 The present invention provides a technical solution: a plug-in connector base for preventing the bending of the plug core, comprising a shell 1, a plug core housing 2, an elastic clamp 3 and a plug pin seat 4, and also comprising a pin lower end 202 and a pin upper end 205 uniformly arranged inside the plug core housing 2 to reduce wear and plugged with the plug pin seat 4, a connecting component arranged between the pin lower end 202 and the pin upper end 205 to perform adaptive compensation according to the wear of the pin upper end 205, a guiding component arranged on the plug core housing 2 to perform preliminary correction on the pin upper end 205, and a pin connector 401 arranged inside the plug pin seat 4 to correspond to the pin upper end 205 and perform secondary correction on it; The upper end 205 of the pin is set as a conical structure, and the bottom of the pin connector 401 is provided with a conical groove matching the upper end 205 of the pin.

[0021] It should be noted that when the connector base is in use, the ferrule housing 2 needs to be fixed in the outer shell 1 through the elastic clip 3, and then the plug pin base 4 is inserted into the assembled connector base, so that the upper end 205 of the pin is inserted into the conical groove at the bottom of the pin connector 401. Among them, the pin connector 401, the lower end 202 of the pin, the upper end 205 of the pin, and the connection component are all made of conductive metal materials, ensuring the conductivity after insertion. During the installation process of the ferrule housing 2, the bent upper end 205 of the pin is preliminarily corrected through the alignment component, and then the conical groove at the bottom of the pin connector 401 during insertion is used to assist the fully corrected upper end 205 of the pin after preliminary correction. And the top of the upper end 205 of the pin is a plane. After the upper end 205 of the pin is inserted into the conical groove at the bottom of the pin connector 401, a conical gap is left between the conical groove and the top of the upper end 205 of the pin.

[0022] The inner wall of the outer shell 1 fits with the outer wall of the ferrule housing 2, and the inner wall of the outer shell 1 is provided with a clamping block 101, and the outer wall of the ferrule housing 2 is provided with a groove 201 matching the clamping block 101.

[0023] It should be noted that the fitting of the ferrule housing 2 with the inner wall of the outer shell 1 can prevent the ferrule housing 2 from shaking when installed in the outer shell 1 and the phenomenon of misalignment during insertion. The clamping block 101 on the inner wall of the outer shell 1 will be correspondingly clamped into the groove 201 on the outer wall of the ferrule housing 2 to position the direction of the ferrule housing 2 after installation, ensuring that the ferrule housing 2 is inserted in the designed direction and avoiding misinsertion or reverse insertion.

[0024] The elastic clip 3 is set as a discontinuous ring structure, and handles are symmetrically arranged at the bottom of the disconnection of the elastic clip 3. And a discontinuous snap ring is arranged on the outer wall of the upper end of the elastic clip 3, and an annular groove matching the discontinuous snap ring is arranged on the inner wall of the lower end of the outer shell 1.

[0025] It should be noted that after the clamping block 101 is completely clamped into the groove 201, pull the handle at the bottom of the disconnection of the elastic clip 3 to make it deform, and then snap the elastic clip 3 into the bottom of the outer shell 1. Use the discontinuous snap ring protruding from the outer wall of the upper end of the elastic clip 3 to snap into the annular groove on the inner wall of the outer shell 1. Release the handle, and the elastic clip 3 will return to its original shape and can be clamped in the outer shell 1. And at this time, the top of the elastic clip 3 can just limit the bottom of the ferrule housing 2, thus completing the assembly of the connector base. Without the need to use other tools, it is easy to install and disassemble, greatly improving the installation and disassembly efficiency.

[0026] The connecting component includes a limiting block 203 that slidably cooperates with the lower end 202 of the pin. A connecting column 204 is connected between the top of the limiting block 203 and the bottom of the upper end 205 of the pin. Limiting columns 206 that penetrate above the limiting block 203 are symmetrically arranged at the bottom of the upper end 205 of the pin. A first spring 207 located outside the limiting columns 206 is connected between the top of the lower end 202 of the pin and the bottom of the upper end 205 of the pin.

[0027] It should be noted that when the upper end 205 of the pin is pressed by the inner wall of the conical groove at the bottom of the pin connecting member 401, the upper end 205 of the pin drives the connecting column 204 to move downward, and drives the limiting block 203 to slide along the lower end 202 of the pin. The upper end 205 of the pin is limited by sliding downward on the top of the lower end 202 of the pin through the limiting columns 206 at the bottom, and under the restoring and pushing action of the compressed first spring 207, the upper end 205 of the pin is in close contact with the inner wall of the conical groove at the bottom of the pin connecting member 401.

[0028] The lower end 202 of the pin is provided with a hollow structure, and a first through hole is opened on the top of the lower end 202 of the pin outside the connecting column 204.

[0029] It should be noted that the hollow lower end 202 of the pin is a conventional existing technology. After the connector base is installed on the device, the lower end 202 of the pin needs to be docked with the plug of the power cord. The first through hole is to avoid forming negative pressure resistance when the limiting block 203 slides along the lower end 202 of the pin.

[0030] The guiding component includes fixed platforms 208 symmetrically arranged on the outer wall of the ferrule housing 2. A fixed cylinder 209 is fixed inside the fixed platform 208. A piston block 210 that slidably cooperates with it is arranged inside the fixed cylinder 209. A top column 211 that penetrates the top of the fixed cylinder 209 is connected to the top of the piston block 210. A second through hole is opened on the top of the fixed cylinder 209 outside the top column 211. A guiding plate 212 located at the bottom of the upper end 205 of the pin is fixed to the top end of the top column 211. An auxiliary driving structure is fixed on the top of the fixed platform 208 on one side of the fixed cylinder 209.

[0031] The auxiliary driving structure includes a fixed groove 213 fixed on the fixed platform 208 and on one side of the fixed cylinder 209. The fixed groove 213 communicates with the lower end of the fixed cylinder 209 through a pipeline. Second springs 214 are symmetrically fixed on the inner wall of the fixed groove 213. The ends of the two second springs 214 are jointly connected to a piston plate 215 that slidably cooperates with the fixed groove 213. A guiding block 216 is fixed to the outer wall of the piston plate 215.

[0032] It should be noted that the fixed table 208 is not a protruding part of the outer wall of the ferrule housing 2, but a part extending inward from the ferrule housing 2, ensuring that both the fixed cylinder 209 and the fixed groove 213 are located inside the outer edge of the ferrule housing 2, and the inside of the fixed cylinder 209 is located in the area below the piston block 210, the inside of the fixed groove 213 is located in the area on one side of the piston plate 215, and the connecting pipeline between the fixed cylinder 209 and the fixed groove 213 is filled with hydraulic oil. The second through hole is for the piston block 210 to slide to avoid negative pressure.

[0033] Under the above conditions, during the process of pushing the ferrule housing 2 into the outer shell 1, the guide block 216 is squeezed. After the guide block 216 is squeezed by the inner wall of the outer shell 1, it pushes the piston plate 215 to slide into the fixed groove 213, and the piston plate 215 squeezes the second spring 214. The piston plate 215 then squeezes the hydraulic oil in the fixed groove 213 into the fixed cylinder 209 through the pipeline at the lower end. The filling of the hydraulic oil pushes the piston block 210 to slide upward in the fixed cylinder 209, and the piston block 210 pushes the ejector pin 211 to move the alignment plate 212 upward. During the upward movement of the alignment plate 212, if the upper end position of the upper end 205 of the pin is bent due to other factors such as transportation, the third through hole of the alignment plate 212 can preliminarily correct the bent position.

[0034] The alignment plate 212 is correspondingly provided with a third through hole matching the bottom of the lower end 202 of the pin, and the edges of the alignment plate 212 and the fixed table 208 are located inside the outer shell 1.

[0035] It should be noted that the third through hole of the alignment plate 212 can correct the bent position. Since the size of the third through hole is the same as the bottom of the upper end 205 of the pin, and the tapered groove at the bottom of the pin connector 401 fits with the upper end 205 of the pin, the size of the third through hole is the same as that of the tapered groove. The upper end 205 of the pin after correction may not be completely corrected, but the upper part of the upper end 205 of the pin can be corrected within the range of the tapered groove at the bottom of the pin connector 401, ensuring that the upper end 205 of the pin can be inserted into the tapered groove during insertion.

[0036] The fixed groove 213 is set as a rectangular structure with an opening facing outward.

[0037] It should be noted that the distance that the guide block 216 moves under extrusion is the same as the distance that the piston plate 215 moves, so that the volume of the hydraulic oil squeezed into the fixed cylinder 209 from the fixed groove 213 can move the alignment plate 212 upward to the upper end of the upper end 205 of the pin.

[0038] The guide block 216 is symmetrically provided with inclined surfaces in the vertical direction, and a rotating roller is provided at the intersection of the inclined surfaces of the guide block 216. The inner wall of the outer shell 1 is provided with a positioning groove 102 that fits with the inclined surface of the guide block 216.

[0039] It should be noted that when the upper inclined surface of the guide block 216 is squeezed by the inner wall of the housing 1, it will move horizontally. During the process of pushing the ferrule housing 2 to move upward in the housing 1, the rotating roller at the intersection of the inclined surfaces of the guide block 216 will roll inside the housing 1. Even if the inner wall of the housing 1 is an arc surface, the rotating roller can roll on its inner wall, reducing the friction when the guide block 216 moves. Until the guide block 216 moves to the positioning groove 102 on the inner wall of the housing 1, the second spring 214 then pushes the piston plate 215 to reset. The guide block 216 is snapped into the positioning groove 102, and the hydraulic oil is drawn back from the fixed cylinder 209. The alignment plate 212 also moves downward to reset. At the same time, the latch 101 is snapped into the groove 201.

[0040] Working principle: First, when using this connector base, it needs to be assembled. The ferrule housing 2 can be pushed in from the bottom of the housing 1. The latch 101 on the inner wall of the housing 1 will be correspondingly snapped into the groove 201 on the outer wall of the ferrule housing 2 to position the direction of the ferrule housing 2 after installation, ensuring that the ferrule housing 2 is inserted in accordance with the designed direction to avoid misinsertion or reverse insertion. Then, pull the handle at the bottom of the disconnection point of the elastic clamping member 3 to cause it to deform, and then snap the elastic clamping member 3 into the bottom of the housing 1. Use the discontinuous clamping ring protruding from the outer wall of the upper end of the elastic clamping member 3 to snap into the annular groove on the inner wall of the housing 1. Release the handle, and the elastic clamping member 3 will deform and recover to be clamped in the housing 1. And at this time, the elastic clamping member 3 can limit the bottom of the ferrule housing 2, thus completing the assembly of this connector base. Without the need to use other tools, it is easy to install and disassemble, greatly improving both the installation and disassembly efficiency.

[0041] Then, while pushing the ferrule housing 2 into the outer shell 1, the upper inclined surface of the guiding block 216 will be squeezed by the inner wall of the outer shell 1. After being squeezed, the guiding block 216 will push the piston plate 215 to slide into the fixing groove 213, and the piston plate 215 will squeeze the second spring 214. Then, the piston plate 215 will squeeze the hydraulic oil in the fixing groove 213 into the fixing cylinder 209 through the pipeline at the lower end. The filling of the hydraulic oil will push the piston block 210 to slide upward in the fixing cylinder 209, and the piston block 210 will push the ejector pin 211 to move the guiding plate 212 upward. During the upward movement of the guiding plate 212, the third through hole on the guiding plate 212 will pass through the bottom of the corresponding upper end 205 of the pin and move upward. If the upper end position of the upper end 205 of the pin is bent due to other factors such as transportation, the third through hole of the guiding plate 212 can correct the bent position. It should be noted that when the upper end 205 of the pin is corrected by the upward force, the limiting block 203 is blocked by the top of the lower end 202 of the pin, so the upward movement of the upper end 205 of the pin is limited. Since the third through hole has the same size as the bottom of the upper end 205 of the pin, and the tapered groove at the bottom of the pin connector 401 fits with the upper end 205 of the pin, the third through hole has the same size as the tapered groove. The corrected upper end 205 of the pin may not be completely corrected, but the upper part of the upper end 205 of the pin can be corrected within the range of the tapered groove at the bottom of the pin connector 401, ensuring that the upper end 205 of the pin can be inserted into the tapered groove during plugging.

[0042] Finally, when inserting the connector base, the plug pin base 4 is correspondingly snapped into the top of the housing 1, and the pin connector 401 is correspondingly inserted into the outer wall of the upper end 205 of the pin. When inserting the non-bent upper end 205 of the pin, the tapered groove of the pin connector 401 will fit on the outer wall of the upper end 205 of the pin, so that the pin connector 401, the upper end 205 of the pin, and the lower end 202 of the pin are electrically connected. When inserting the bent and initially corrected upper end 205 of the pin, there may still be a small amount of bending in the upper part of the upper end 205 of the pin, and the top of the upper end 205 of the pin is within the range of the tapered groove of the pin connector 401. When the pin connector 401 moves downward, the inner wall of the tapered groove makes hard contact with the bent part of the upper end 205 of the pin. During the continuous downward pressing of the pin connector 401, the bent upper end 205 of the pin will be pressed, the upper end 205 of the pin drives the connecting column 204 to move downward, and drives the limiting block 203 to slide along the lower end 202 of the pin. The upper end 205 of the pin is limited by the bottom limiting column 206 to slide downward on the top of the lower end 202 of the pin. After continued insertion, under the action of hard contact, the slightly bent upper end 205 of the pin is also corrected, so that the fully corrected upper end 205 of the pin fits into the tapered groove at the bottom of the pin connector 401. When the plug pin base 4 cannot be pressed, it means that the bottom of the upper end 205 of the pin moves to the top of the lower end 202 of the pin. Under the reaction force of the first spring 207, the upper end 205 of the pin is in close contact with the inner wall of the tapered groove at the bottom of the pin connector 401, that is, the insertion process is completed. After the above correction process and during subsequent use, when the upper end 205 of the pin is worn due to multiple insertions and extractions, since the upper end 205 of the pin is a tapered structure, it is still a tapered structure after wear, and the top of the upper end 205 of the pin is not pointed but flat. The wear causes a slight reduction in the volume of the upper end 205 of the pin. Under the reaction force of the first spring 207, the upper end 205 of the pin can still be in close contact with the inner wall of the tapered groove at the bottom of the pin connector 401. Each group of upper ends 205 of the pins can adaptively snap into different depths of the tapered groove according to the wear condition, thus ensuring the tightness of the insertion between the pin connector 401 and the upper end 205 of the pin, and avoiding the phenomenon of poor contact due to wear.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
