Description

Technical Field

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

[0002] A plug-in connector is a common type of connector that connects circuits by inserting a plug into a socket. Connectors include components such as a plug, a socket, contacts, and a housing. A plug is usually a component with a pin or pin holder on one end for insertion into a socket. A socket is a component with a jack or socket that receives the plug and is usually fixed to the device. Contacts are small metal components inside the plug and socket that are responsible for the actual electrical connection. The housing is an external structure that protects the internal contacts from external environmental influences. Plug-in connectors are designed for frequent plugging and unplugging, making them easy to repair and replace. The socket with pins is also called a connector base. It consists of a housing and an internal ferrule. The ferrule contains different numbers of pins depending on the model and the connection line. The head of the pin needs to be plugged into the pin holder in the plug, and the tail of the pin needs to be connected to the pin holder of the power cord plug. The head of the pin usually matches the metal contact of the pin holder in the plug to ensure close contact and maintain a good electrical connection.

[0003] In the prior art, although the connector base and the plug adopt a plug-in connection method, which is convenient for plugging and maintenance, each connector has a certain plug-in life. Since the pins on the ferrule are in hard contact with the needle seat when plugged in, severe wear is easily caused during the continuous plug-in and pull-out process, resulting in reduced contact tightness between the pins and the metal contacts in the needle seat after multiple plug-ins, thereby affecting the electrical connection of the connector during plugging and easily causing poor contact.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original plug-in connector base. Summary of the Invention

[0005] The technical solution of the present invention addresses the technical problem that the existing technical solutions are too simple, and provides a solution that is significantly different from the existing technology. Specifically, the purpose of the present invention is to provide a plug-in connector base that prevents the core from bending, so as to solve the problem raised in the above background technology that the pins are easily worn and poor contact occurs after repeated plugging and unplugging.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a plug-in connector base that prevents ferrule bending, comprising a housing, a ferrule housing, an elastic clamp, and a plug pin socket, further comprising: a lower pin end and an upper pin end uniformly arranged inside the ferrule housing to reduce wear and engage with the plug pin socket; a connecting assembly arranged between the lower pin end and the upper pin end to adaptively compensate for wear of the upper pin end; a guide assembly arranged on the ferrule housing to perform preliminary correction of the upper pin end; and a pin connector arranged inside the plug pin socket to correspondingly engage with the upper pin end and perform secondary correction thereof;

[0007] The upper end of the pin is configured as a tapered structure, and the bottom of the pin connector is configured as a tapered groove matching the upper end of the pin.

[0008] Preferably, the inner wall of the shell fits with the outer wall of the ferrule housing, and the inner wall of the shell is provided with a clamping block, and the outer wall of the ferrule housing is provided with a groove matching the clamping block.

[0009] Preferably, the elastic clip is configured as a disconnected annular structure, and a handle is symmetrically provided at the bottom of the disconnected portion of the elastic clip, and a disconnected snap ring is provided on the upper outer wall of the elastic clip, and an annular groove matching the disconnected snap ring is provided on the lower inner wall of the shell.

[0010] Preferably, the connecting assembly includes a limit block that slides with the lower end of the pin, a connecting column is connected between the top of the limit block and the bottom of the upper end of the pin, the bottom of the upper end of the pin is symmetrically provided with limit columns that pass through the top of the limit block, and a first spring located on the outside of the limit column is connected between the top of the lower end of the pin and the bottom of the upper end of the pin.

[0011] Preferably, the lower end of the pin is configured as a hollow structure, and a first through hole is provided at the top of the lower end of the pin, which is located on the outside of the connecting column.

[0012] Preferably, the guide assembly includes a fixed table symmetrically arranged on the outer wall of the core shell, a fixed cylinder is fixed on the inner side of the fixed table, a piston block slidingly matched with the fixed cylinder is arranged inside the fixed cylinder, the top of the piston block is connected to a top column passing through the top of the fixed cylinder, a second through hole is provided on the outside of the top column at the top of the fixed cylinder, a guide plate located at the bottom of the upper end of the pin is fixed to the top of the fixed table, and an auxiliary driving structure located on one side of the fixed cylinder is fixed to the top of the fixed table.

[0013] Preferably, the auxiliary drive structure includes a fixed groove fixed on the fixed table and located on one side of the fixed cylinder, and the fixed groove is connected to the lower end of the fixed cylinder through a pipeline, and the inner wall of the fixed groove is symmetrically fixed with a second spring, and the ends of the two second springs are commonly connected to a piston plate that slides with the fixed groove, and the outer wall of the piston plate is fixed with a guide block.

[0014] Preferably, a third through hole is provided on the guide plate to match the bottom of the lower end of the pin, and the edges of the guide plate and the fixing table are located on the inner side of the shell.

[0015] Preferably, the fixing groove is configured as a rectangular structure with its opening facing outward.

[0016] Preferably, the guide block 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, and the inner wall of the shell is provided with a positioning groove that fits with the inclined surfaces of the guide block.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention is provided with a specially structured elastic clamping piece. When the handle is pulled, it is deformed. The break-away clamping ring protruding from the outer wall of the upper end of the elastic clamping piece is clamped into the annular groove on the inner wall of the shell. When the handle is released, the elastic clamping piece is deformed and can be clamped in the shell. At this time, the elastic clamping piece can limit the bottom of the ferrule shell, thereby completing the assembly of the connector base. No other tools are required, and it is easy to install and disassemble, which greatly improves the installation and disassembly efficiency.

[0019] The present invention provides a guide assembly, which utilizes the inclined surface of the guide block to trigger after the insert housing is pushed into the outer shell, and the guide plate is moved up to a suitable position by squeezing and conveying the oil. During the upward movement of the guide plate, if the upper end of the upper end of the pin is bent due to transportation or other factors, the third through hole of the guide plate can correct the bent position. The corrected upper end of the pin may not be completely corrected, but the upper end portion of the upper end of the pin can be corrected to the range of the tapered groove at the bottom of the pin connector, ensuring that the upper end of the pin can be inserted into the tapered groove during insertion, thereby preventing the upper end portion of the upper end of the pin from bending beyond the range of the tapered groove and making insertion impossible.

[0020] The present invention provides a pin upper end with a tapered structure and a pin connector with a matching tapered groove. During the plugging process, the pin upper end that has been initially corrected is completely corrected due to the action of hard contact. Secondly, since the top of the pin upper end is a plane, the volume of the pin upper end decreases slightly due to wear, but the shape after wear is still tapered. Under the reverse push of the first spring, the pin upper end is always in close contact with the inner wall of the tapered groove at the bottom of the pin connector. The upper ends of each group of pins can be adaptively inserted into different depths of the tapered groove according to the wear conditions, thereby ensuring the tightness of the plugging between the pin connector and the pin upper end and avoiding poor contact due to wear.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1 to 10The present invention provides a technical solution: a plug-in connector base that prevents ferrule bending, comprising a housing 1, a ferrule housing 2, an elastic clamp 3, and a plug pin base 4, further comprising a pin lower end 202 and a pin upper end 205 evenly arranged inside the ferrule housing 2 to reduce wear and plug into the plug pin base 4, a connecting assembly arranged between the pin lower end 202 and the pin upper end 205 to adaptively compensate for wear of the pin upper end 205, a guide assembly arranged on the ferrule housing 2 to perform preliminary correction of the pin upper end 205, and a pin connector 401 arranged inside the plug pin base 4 to correspond to and be plugged into the pin upper end 205 and perform secondary correction thereof;

[0034] The upper end 205 of the pin is configured as a conical structure, and the bottom of the pin connector 401 is configured with a conical groove matching the upper end 205 of the pin.

[0035] It should be noted that when the connector base is in use, the plug housing 2 needs to be fixed in the shell 1 by the elastic clip 3, and then the plug pin holder 4 is plugged into the assembled connector base so that the upper end 205 of the pin is inserted into the tapered groove at the bottom of the pin connector 401, wherein the pin connector 401, the lower end 202 of the pin, the upper end 205 of the pin and the connecting component are all made of conductive metal, which ensures the conductivity after plugging. During the installation of the plug housing 2, the bent upper end 205 of the pin is preliminarily corrected by the guide component, and then the tapered groove at the bottom of the pin connector 401 is used to assist in the complete correction of the preliminarily corrected upper end 205 of the pin during plugging, and the top of the upper end 205 of the pin is flat. After the upper end 205 of the pin is inserted into the tapered groove at the bottom of the pin connector 401, a tapered gap is left between the tapered groove and the top of the upper end 205 of the pin.

[0036] The inner wall of the shell 1 is matched with the outer wall of the ferrule housing 2 , and the inner wall of the 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 .

[0037] It should be noted that the fit between the ferrule shell 2 and the inner wall of the shell 1 can prevent the ferrule shell 2 from shaking when installed in the shell 1, and misalignment during insertion. The card block 101 on the inner wall of the shell 1 will correspond to the groove 201 on the outer wall of the ferrule shell 2, positioning the direction of the ferrule shell 2 after installation, ensuring that the ferrule shell 2 is inserted in the designed direction to avoid misinsertion or reverse insertion.

[0038] The elastic clip 3 is configured as a disconnected annular structure, and a handle is symmetrically provided at the bottom of the disconnected portion of the elastic clip 3, and a disconnected snap ring is provided on the upper outer wall of the elastic clip 3, and an annular groove matching the disconnected snap ring is provided on the lower inner wall of the shell 1.

[0039] It should be noted that after the card block 101 is fully inserted into the groove 201, pull the handle at the bottom of the disconnected part of the elastic card 3 to deform it, and then insert the elastic card 3 into the bottom of the shell 1, and use the disconnected clamping ring raised on the outer wall of the upper end of the elastic card 3 to insert it into the annular groove on the inner wall of the shell 1. Release the handle, and the elastic card 3 will be deformed and restored to be stuck in the shell 1. At this time, the top of the elastic card 3 can just limit the bottom of the core shell 2, thereby completing the assembly of the connector base. No other tools are required, and it is easy to install and disassemble, which greatly improves the installation and disassembly efficiency.

[0040] The connecting assembly includes a limit block 203 that slides with the lower end 202 of the pin, a connecting column 204 is connected between the top of the limit block 203 and the bottom of the upper end 205 of the pin, and a limit column 206 that passes through the top of the limit block 203 is symmetrically arranged at the bottom of the upper end 205 of the pin. A first spring 207 located on the outside of the limit column 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.

[0041] It should be noted that when the upper end 205 of the pin is pressed by the conical groove wall at the bottom of the pin connector 401, the upper end 205 of the pin drives the connecting column 204 to move downward, and drives the limit block 203 to slide against the lower end 202 of the pin. The upper end 205 of the pin slides downward on the top of the lower end 202 of the pin through the bottom limit column 206 for limitation, and under the restoring reverse push 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 connector 401.

[0042] The lower end 202 of the pin is configured as a hollow structure, and a first through hole is defined at the top of the lower end 202 located outside the connecting column 204 .

[0043] It should be noted that the hollow structure of the 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 the formation of negative pressure resistance when the limit block 203 slides against the lower end 202 of the pin.

[0044] The guiding assembly includes a fixed table 208 symmetrically arranged on the outer wall of the core shell 2, a fixed cylinder 209 is fixed on the inner side of the fixed table 208, a piston block 210 slidingly matched with the fixed cylinder 209 is arranged inside the fixed cylinder 209, the top of the piston block 210 is connected to a top column 211 passing through the top of the fixed cylinder 209, a second through hole is provided at the top of the fixed cylinder 209 on the outside of the top column 211, a guide plate 212 located at the bottom of the upper end 205 of the pin is fixed to the top of the fixed table 208, and an auxiliary driving structure located on one side of the fixed cylinder 209 is fixed to the top of the fixed table 208.

[0045] The auxiliary drive structure includes a fixed groove 213 fixed on the fixed table 208 and located on one side of the fixed cylinder 209, and the fixed groove 213 is connected to the lower end of the fixed cylinder 209 through a pipeline. The inner wall of the fixed groove 213 is symmetrically fixed with a second spring 214, and the ends of the two second springs 214 are commonly connected to a piston plate 215 that slides with the fixed groove 213, and the outer wall of the piston plate 215 is fixed with a guide block 216.

[0046] It should be noted that the fixed table 208 is not a protruding part of the outer wall of the plug shell 2, but a part extending toward the inner side of the plug shell 2, ensuring that the fixed cylinder 209 and the fixed groove 213 are both located on the inner side of the outer edge of the plug shell 2, and the interior of the fixed cylinder 209 is located in the area below the piston block 210, the interior of the fixed groove 213 is located in the area on one side of the piston plate 215, and the connecting pipes between the fixed cylinder 209 and the fixed groove 213 are all filled with oil, wherein the second through hole is for the sliding of the piston block 210 to avoid negative pressure.

[0047] Under the above conditions, in the process of pushing the core shell 2 into the shell 1, the guide block 216 is squeezed. After being squeezed by the inner wall of the shell 1, the guide block 216 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 squeezes the oil in the fixed groove 213 into the fixed cylinder 209 through the pipeline at the lower end. The filling of the oil pushes the piston block 210 to slide upward in the fixed cylinder 209. The piston block 210 pushes the top column 211 to move the guide plate 212 upward. During the upward movement of the guide plate 212, if the upper end position of the pin upper end 205 is bent due to transportation or other factors, the third through hole of the guide plate 212 can preliminarily correct the bent position.

[0048] A third through hole is correspondingly formed on the guide plate 212 to match the bottom of the lower end 202 of the pin, and the edges of the guide plate 212 and the fixing table 208 are located on the inner side of the housing 1.

[0049] It should be noted that the third through hole of the guide plate 212 can correct the bent position. Since the third through hole is the same size as the bottom of the pin upper end 205, and the conical groove at the bottom of the pin connector 401 fits with the pin upper end 205, the third through hole and the conical groove are the same size. The corrected pin upper end 205 may not be completely corrected, but the upper end part of the pin upper end 205 can be corrected to within the range of the conical groove at the bottom of the pin connector 401, ensuring that the pin upper end 205 can be inserted into the conical groove during insertion.

[0050] The fixing groove 213 is configured as a rectangular structure with its opening facing outward.

[0051] It should be noted that the distance the guide block 216 is squeezed and moved causes the piston plate 215 to move the same distance, so that the volume of oil squeezed into the fixed cylinder 209 by the fixed groove 213 can move the guide plate 212 to the upper end of the pin upper end 205.

[0052] 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 housing 1 is provided with a positioning groove 102 that fits with the inclined surfaces of the guide block 216 .

[0053] It should be noted that the upper inclined surface of the guide block 216 will move horizontally due to the squeezing of the inner wall of the shell 1. In the process of pushing the core shell 2 upward in the shell 1, the rotating roller at the intersection of the inclined surfaces of the guide block 216 will roll inside the shell 1. Even if the inner wall of the shell 1 is an arc surface, the rotating roller can also roll on its inner wall, reducing the friction of the guide block 216 when it moves, until the guide block 216 moves to the positioning groove 102 on the inner wall of the shell 1, the second spring 214 pushes the piston plate 215 to reset, the guide block 216 is stuck in the positioning groove 102, the oil is drawn back from the fixed cylinder 209, the guide plate 212 will also move down and reset, and at the same time the block 101 is stuck in the groove 201.

[0054] Working principle: First, the connector base needs to be assembled when it is used. The plug shell 2 can be pushed from the bottom of the shell 1, and the block 101 on the inner wall of the shell 1 will be correspondingly inserted into the groove 201 on the outer wall of the plug shell 2. Position the direction of the plug shell 2 after installation to ensure that the plug shell 2 is inserted in the designed direction to avoid misinsertion or reverse insertion. Then pull the handle at the bottom of the disconnection point of the elastic clip 3 to deform it, and then insert the elastic clip 3 into the bottom of the shell 1. Use the disconnection ring raised on the outer wall of the upper end of the elastic clip 3 to insert it into the annular groove on the inner wall of the shell 1. Release the handle, and the elastic clip 3 can be deformed and restored to be stuck in the shell 1. At this time, the elastic clip 3 can limit the bottom of the plug shell 2, thereby completing the assembly of the connector base. No other tools are required, and it is easy to install and disassemble, which greatly improves the efficiency of installation and disassembly.

[0055] Then, when the insert housing 2 is pushed into the shell 1, the upper inclined surface of the guide block 216 will be squeezed by the inner wall of the shell 1. After being squeezed, the guide block 216 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 squeezes the oil in the fixed groove 213 into the fixed cylinder 209 through the pipeline at the lower end. The filling of the oil pushes the piston block 210 to slide upward in the fixed cylinder 209. The piston block 210 pushes the top column 211 to move the guide plate 212 upward. During the upward movement of the guide plate 212, the third through hole on the guide plate 212 passes through the bottom of the corresponding pin upper end 205 and moves upward. If the upper end position of the pin upper end 205 is due to movement, When bending is caused by other factors such as loss of transmission, the third through hole of the guide 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 limit block 203 is blocked by the top of the lower end 202 of the pin, thereby limiting the upward movement of the upper end 205 of the pin. Since the bottom size of the third through hole is the same as that of the upper end 205 of the pin, the conical groove at the bottom of the pin connector 401 fits with the upper end 205 of the pin, then the third through hole and the conical groove have the same size. The corrected upper end 205 of the pin may not be completely corrected, but the upper end part of the upper end 205 of the pin can be corrected to the range of the conical groove at the bottom of the pin connector 401, to ensure that the upper end 205 of the pin can be inserted into the conical groove during insertion.

[0056] Finally, when the connector base is plugged in, the plug pin holder 4 is correspondingly inserted into the top of the housing 1, and the pin connector 401 is correspondingly plugged into the outer wall of the pin upper end 205. When the unbent pin upper end 205 is plugged in, the tapered groove of the pin connector 401 will fit into the outer wall of the pin upper end 205, so that the pin connector 401, the pin upper end 205 and the pin lower end 202 form an electrical connection. When the bent pin upper end 205 is plugged in and initially corrected, the upper part of the pin upper end 205 may still be slightly bent, and the plug The top of the pin upper end 205 is located within the conical groove of the pin connector 401. When the pin connector 401 moves downward, the inner wall of the conical groove makes hard contact with the curved portion of the pin upper end 205. As the pin connector 401 is continuously pressed downward, the curved pin upper end 205 will be pressed. The pin upper end 205 drives the connecting column 204 to move downward, and drives the limiting block 203 to slide against the pin lower end 202. The pin upper end 205 slides downward on the top of the pin lower end 202 through the bottom limiting column 206 to be limited. After continued insertion, the pin upper end 205 is in hard contact with the connecting column 204. The slightly bent upper end 205 of the pin is also corrected, so that the fully corrected upper end 205 fits into the tapered groove at the bottom of the pin connector 401. When the plug pin holder 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 reverse push 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, and the plugging process is completed. After the above correction process and in subsequent use, when the upper end 205 of the pin is worn due to repeated plugging and unplugging, the upper end of the pin is loose. 205 is a conical structure, which remains conical after wear, and the top of the pin upper end 205 is not pointed but flat. The wear causes the pin upper end 205 to shrink slightly in volume. Under the reverse push of the first spring 207, the pin upper end 205 can still be in close contact with the inner wall of the conical groove at the bottom of the pin connector 401. Each group of pin upper ends 205 can be adaptively inserted into the different depths of the conical groove according to the wear condition, thereby ensuring the tightness of the plug-in connection between the pin connector 401 and the pin upper end 205, and avoiding poor contact due to wear.

[0057] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
