Description

Technical Field

[0001] The present invention relates to the technical field of high-speed connectors, and in particular to a high-speed connector. Background Art

[0002] A high-speed connector is a low-cost, short-distance connection device. Its high-speed cable has excellent attenuation performance, low latency, and anti-interference, and can achieve high-frequency broadband transmission. A high-speed connector usually includes a pair of plugs and sockets that cooperate with each other. The plug and socket are connected to form a bridge for circuit circulation or signal connectivity. Regardless of the type of connector, it is widely used in electronic, electrical, and mechanical fields, and enables the circuit to achieve the predetermined function, and it is necessary to ensure the stability and safety of the connector during use.

[0003] When the current connector is in use, the conductive connection cannot always be in elastic contact, which is prone to connection interruption, reducing the connection efficiency. At the same time, it is easy for gaps to appear between the conductive connections. The contact surface between the conductive connections is easily oxidized when exposed to the air, increasing the contact resistance and affecting the conductive performance. When elastic contact is used, for example, a plastic (elastic) insulating material pad with a signal terminal (i.e., used for conduction or signal transmission) can be elastically deformed along the fitting part, so that the conductive connection fits tightly. After multiple plugging and unplugging, the plastic insulating material pad with the signal terminal is prone to fatigue deformation, resulting in insufficient contact pressure at the conductive connection, which is prone to connection interruption, or interference with plugging and unplugging (for example, the end projections of the plastic insulating material pad overlap), affecting the smoothness when plugging and unplugging again, and it is also easy for the plastic insulating material pad to crack or break when subjected to a certain lateral force, further reducing the stability and durability of the connection end. Summary of the invention

The displacement margin can prevent the locking point from loosening due to vibration after the locking assembly locks the socket assembly and the plug assembly at a fixed point, making it difficult to re-position and lock after plugging and unplugging (that is, when locking through screws, the screw hole becomes larger or the screw has thread slippage due to vibration). When the plug assembly needs to be unplugged, the limit of the locking assembly is released, and the second connecting terminal slides out of the splicing cavity along the first direction. The block and the second connecting terminal are reset after relative sliding, thereby preventing the second connecting terminal from being elastically deformed due to the abutment with the protruding mechanism, resulting in the second connecting terminal and the first connecting terminal end projecting overlap when reinserted, affecting the smoothness when reinserted, and also preventing the second connecting terminal or the first connecting terminal from being accidentally subjected to lateral force and causing cracking or breakage, thereby improving the stability and durability of the connection.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. All other embodiments obtained by ordinary technicians in the field without making creative work based on the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0030] See also Figures 1 to 6 The present invention provides a technical solution: a high-speed connector, comprising:

[0031] The socket assembly 100 includes a socket shell 110, an end surface of the socket shell 110 is provided with a splicing cavity 111; a protrusion mechanism is arranged in the socket shell 110, and the protrusion mechanism is at least partially located in the splicing cavity 111; a first connection terminal 130 is arranged in the socket shell 110, one end of the first connection terminal 130 is at least partially located in the splicing cavity 111, and the other end is connected to an external electrical connection assembly through a cable;

[0032] The plug assembly 200 includes a second connection terminal 210, one end of which is connected to an external electrical connection assembly through a cable, and the other end of which is inserted into the splicing cavity 111 along the first direction to be electrically connected to the first connection terminal 130, and the side surface at least partially abuts against the protrusion mechanism located in the splicing cavity 111; a stopper 221 slidably connected to the second connection terminal 210 along the first direction, and the end surface of the stopper 221 at least partially overlaps with the projection of the first connection terminal 130 along the first direction;

[0033] The locking assembly 300 is used to lock and limit the connection between the socket assembly 100 and the plug assembly 200, and has a displacement margin along the first direction;

[0034] The end surface of the socket shell 110 is provided with a splicing cavity 111 for accommodating the plug assembly 200, providing a splicing space for splicing between the socket assembly 100 and the plug assembly 200. The socket shell 110 provides mechanical support and protection and accommodates other components. At the same time, the socket shell 110 is made of insulating material. The splicing cavity 111 is also used for inserting and positioning the plug assembly 200 to ensure the accuracy of the connection. The protruding mechanism is used to provide positioning and auxiliary mechanical fixing to ensure that the plug assembly 200 will not loosen after insertion or increase damping to improve the clamping force, and also prevent the plug assembly 200 from being inserted. After insertion, it will not shake left and right, ensuring that the second connection terminal 210 can be stably fixed after being inserted into the splicing cavity 111, and will not loosen due to external force or vibration, thereby improving the reliability of mechanical connection and being suitable for application scenarios that require frequent plugging and unplugging or work in a vibration environment. The first connection terminal 130 is electrically connected to the second connection terminal 210 of the plug assembly 200 to ensure the stability of signal transmission. Through the connection between the stopper 221 and the second connection terminal 210, the stopper 221 and the second connection terminal 210 move toward the splicing cavity 111 along the first direction at the same time. When the movement When the stopper 221 abuts against the first connection terminal 130, the first connection terminal 130 cannot continue to move along the first direction because it abuts against the stopper 221. At this time, the stopper 221 slides relatively with the second connection terminal 210, and the second connection terminal 210 continues to move along the first direction into the splicing cavity 111, and at the same time, the surface of the second connection terminal 130 is attached to the first connection terminal 130 and is electrically connected to the first connection terminal 130. Since the first connection terminal 130 and the stopper 221 at least partially overlap in projection along the first direction, the first connection terminal 130 can affect the movement of the stopper 221. Interference is formed to prevent the stopper 221 from moving with the stopper 221, so that the stopper 221 and the second connection terminal 210 slide relative to each other. During use after connection, the stopper 221 and the end face of the first connection terminal 130 remain in a tight state. The locking assembly 300 is used to lock and limit the connection between the socket assembly 100 and the plug assembly 200 after the first connection terminal 130 is electrically connected to the second connection terminal 210. At the same time, a certain displacement margin is provided along the first direction, allowing a certain displacement to adapt to thermal expansion and contraction or mechanical vibration, thereby ensuring the continuous stability of the connection.

[0035] In this embodiment, as a preferred solution, the plug assembly 200 further includes a plug shell 220, the second connection terminal 210 is fixedly connected to the end surface of the plug shell 220 facing the socket shell 110, the end surface of the plug shell 220 is slidably connected to the stopper 221 through the opening of the receiving groove 222, and a first spring 223 is provided between the bottom of the receiving groove 222 and the stopper 221;

[0036] Through the connection between the plug shell 220 and the stopper 221, the plug shell 220 can drive the second connecting terminal 210 and the stopper 221 to move along the first direction, and at the same time, the stopper 221 can slide back and forth in the plug shell 220 along the first direction. Through the connection between the stopper 221 and the second connecting terminal 210, the side surface of the stopper 221 fits with the side surface of the second connecting terminal 210 to avoid deformation of the second connecting terminal 210 after being pressed by the protruding mechanism, which affects mechanical interference during secondary insertion. Through the action of the first spring 223, the stopper 221 and the second connecting terminal 210 move toward the splicing cavity 111 along the first direction at the same time. When the stopper 221 moves to abut against the first connecting terminal 130, the first connecting terminal 130 cannot continue to move along the first direction because it abuts against the stopper 221. At this time, the stopper 221 and the second connecting terminal 210 slide relatively, and the second connecting terminal 210 continues to When moving toward the splicing cavity 111 along the first direction, the first spring 223 is gradually compressed. During the connection and conductive use, the first spring 223 continues to remain in a compressed state. When disassembling, the first spring 223 applies an elastic force to the stopper 221, pushing the stopper 221 to move and reset along the first direction until the surface of the stopper 221 completely coincides with the side surface of the second connecting terminal 210 (that is, the side surface of the second connecting terminal 210 completely fits the surface of the stopper 221). At the same time, due to the elastic force, when the locking assembly 300 is released from the limit, the elastic force of the stopper 221 can be transmitted to the end surface of the first connecting terminal 130. The elastic force of the first spring 223 acts on the plug shell 220, forming a reaction force relative to the stopper 221, pushing the plug shell 220 to drive the second connecting terminal 210 to move, and assisting the second connecting terminal 210 to disengage from the splicing cavity 111, thereby facilitating disassembly.

[0037] In this embodiment, as a preferred solution, the second connection terminal 210 includes two symmetrically arranged second connection heads 211 and second conductive sheets 212 fixedly connected to opposite surfaces of the second connection heads 211, the stopper 221 is sleeved on the outer surfaces of the two second connection heads 211 through the grooves provided, and the stopper 221 is provided with a second polishing sheet 224 corresponding to the inner side wall of the second conductive sheet 212, and the second polishing sheet 224 is in contact with and connected to the surface of the second conductive sheet 212;

[0038] The second conductive sheet 212 is arranged by two second connectors 211. When connected to the first connector 130, the two second conductive sheets 212 conduct electricity or transmit signals at the first connector 130. At the same time, the second conductive sheet 212 is connected to an external electrical connection component through a cable for transmitting signals or conducting electricity. The stopper 221 is sleeved on the outer surface of the second connector 211. The stopper 221 is equivalent to a protective sleeve 112. When in use, the protective sleeve 112 moves relative to the second connector 211, that is, the portion of the second connector 211 provided with the second conductive sheet 212 is exposed. When pulled out, the protective sleeve 112 moves relative to the second connector 211, that is, the second conductive sheet 212 is exposed. The connector 211 and the portion provided by the second conductive sheet 212 are wrapped together, and through the second polishing sheet 224 provided on the stopper 221 corresponding to the second conductive sheet 212, when the stopper 221 and the second connector 211 move relatively, friction is generated between the second polishing sheet 224 and the second conductive sheet 212, and the second conductive sheet 212 can be polished. Therefore, when the stopper 221 is pulled out after use, it can assist in shaping the second connector 211, thereby preventing the second connector 211 from being affected by deformation and being plugged in again, and at the same time, it can also polish the second conductive sheet 212, thereby preventing the contact resistance from increasing due to rust on the second conductive sheet 212 when it is used again, thereby affecting the conductive performance.

[0039] In this embodiment, as a preferred solution, the locking assembly 300 includes a locking ball 310, a locking block 320, a locking sleeve 330 and a reset mechanism 340. The surface of the socket shell 110 is sleeved on the outer surface of the locking ball 310 through a receiving groove. The locking ball 310 can be lifted and lowered in the receiving groove and is at least partially located in the splicing cavity 111. The locking block 320 is arranged on the second connecting terminal 210. The locking sleeve 330 is sleeved on the outer surface of the plug shell 220 and can reciprocate along the first direction. The fixed end of the reset mechanism 340 is fixedly connected to the outer surface of the plug shell 220, and the reset end is connected to the locking sleeve 330.

[0040] When the locking block 320 moves along the first direction with the second connection terminal 210, one end surface of the locking block 320 contacts the locking ball 310 to make the locking ball 310 rise, and the locking block 320 moves to the preset position, the locking ball 310 descends and is located on one side of the other end surface of the locking block 320, and the locking sleeve 330 moves to the top of the locking ball 310 and covers the storage groove, so that the locking ball 310 cannot rise, and the other end surface of the locking block 320 cannot be locked by the locking ball 310;

[0041] The locking block 320 is a block structure with a trapezoidal cross section. When the locking block 320 moves along the first direction toward the splicing cavity 111 with the second connecting terminal 210, one of the inclined surfaces first contacts the locking ball 310, and then the locking ball 310 rises along the inclined slope until it moves to the surface parallel to the locking block 320. The locking ball 310 maintains its height. When the other inclined slope of the locking block 320 contacts the locking ball 310, the locking ball 310 descends along the inclined slope, and then the locking sleeve 330 is sleeved on the socket shell. 110, shielding the receiving groove, the locking ball 310 is blocked by the locking sleeve 330 at the notch of the receiving groove and cannot rise, that is, the locking block 320 cannot pass through the other inclined slope of the locking block 320 along the original path, thereby achieving locking. During installation, the socket shell 110 slides on the plug shell 220 along the first direction away from the socket shell 110. After the locking ball 310 passes through the other inclined slope of the locking block 320, the locking sleeve 330 can be pushed to be sleeved on the socket shell 110 through the setting of the reset mechanism 340.

[0042] In this embodiment, as a preferred solution, the reset mechanism 340 includes a fixed rod 341, a second spring 342 and a reset rod 343, one end of the fixed rod 341 is fixedly connected to the surface of the plug shell 220, the surface of the locking sleeve 330 is sleeved on the other end of the fixed rod 341 through an opened groove, one end of the reset rod 343 is fixedly connected to the bottom of the groove opened in the locking sleeve 330, the end surface of the fixed rod 341 located in the locking sleeve 330 is slidably connected to the reset rod 343 through the opened groove, the second spring 342 is sleeved on the outer surface of the reset rod 343 and one end thereof abuts against the end surface of the fixed rod 341 located in the locking sleeve 330;

[0043] The second spring 342 is sleeved on the outer surface of the reset rod 343, and one end thereof abuts against the end surface of the fixing rod 341 in the locking sleeve 330 to provide a reset force. When the locking sleeve 330 is pushed, the second spring 342 is compressed and stores energy. When the locking sleeve 330 is released, the spring returns to its original state and pushes the reset rod 343 back to its initial position. Through the action of the second spring 342, the reset rod 343 slides and pushes the locking sleeve 330 to reset. Through the groove provided in the locking sleeve 330, the locking sleeve 330 can slide on the fixing rod 341. The reset function is realized through the cooperation of the reset rod 343 and the spring. The second spring 342 enables the locking sleeve 330 to continuously maintain its initial position to avoid accidental sliding that causes the storage slot to be exposed. At the same time, the locking operation steps are locked, the locking efficiency is improved, and it is more convenient to use.

[0044] In this embodiment, as a preferred scheme, the surface of the second connecting head 211 is fixedly connected to the limiting block 213, and the surface of the locking block 320 corresponding to the limiting block 213 is provided with a sliding groove extending along the second direction. The locking block 320 is slidably connected to the outer surface of the limiting block 213 through the sliding groove. Through the cooperation between the limiting block 213 and the locking block 320, the locking block 320 can slide on the limiting block 213. The purpose is that the second connecting head 211 supports the locking block 320, and at the same time, the locking block 320 does not affect the elastic deformation of the second connecting head 211. The length of the extension of the sliding groove is one and a half times to two times the size of the locking block 320, that is, the length of the sliding of the locking block 320 along the second direction is a small sliding.

[0045] In this embodiment, as a preferred solution, a protective sleeve 112 is slidably connected in the splicing cavity 111, and the end surface of the protective sleeve 112 is slidably connected to the outer surface of the first connecting terminal 130 through the through hole. A third spring 113 is arranged between the protective sleeve 112 and the cavity bottom of the splicing cavity 111. Through the connection between the protective sleeve 112 and the first connecting terminal 130, the protective sleeve 112 is used to be sleeved on the first connecting terminal 130 after the second connecting terminal 210 is released, and is used to maintain the position of the first connecting terminal 130 to prevent the first connecting terminal 130 from elastic deformation. Through the action of the third spring 113, when the second connecting terminal 210 is inserted, the second connecting terminal 210 The protective sleeve 112 is pressed against and continues to move, and the third spring 113 is compressed and stores energy. When disassembling, the third spring 113 applies an elastic force to the protective sleeve 112 to push the protective sleeve 112 to move and reset along the first direction. At the same time, the elastic force generated by the first spring 223 and the third spring 113 can assist in ejection disassembly, reduce the resistance when pulling out the plug assembly 200, improve convenience, and facilitate disassembly in a small space. For example, when the plug assembly 200 and the socket assembly 100 are both close to the wall panel or close to the wall panel, or at an angle, the operator can place it when there are fewer force points on the plug assembly 200, and facilitate disassembly through the cooperation of the first spring 223 and the third spring 113.

[0046] In this embodiment, as a preferred solution, the first connecting terminal 130 includes a first connecting head 131, a first conductive sheet 132 and a first polishing sheet 133. The first connecting head 131 is fixedly connected to the bottom of the splicing cavity 111. The first conductive sheet 132 is installed on the side of the first connecting head 131 corresponding to the second conductive sheet 212. The first polishing sheet 133 is arranged on the inner wall of the protective cover 112 corresponding to the first conductive sheet 132. The first connecting head 131 supports the first conductive sheet 132, and the first conductive sheet 132 contacts the second conductive sheet 212 for electrical conduction or signal transmission. The first polishing sheet 133 polishes the first conductive sheet 132 as the protective cover 112 moves to prevent rust. At the same time, when not in use, the protective cover 112 is covered on the outside of the first conductive sheet 132 to reduce contact with the outside world and increase the service life of the first conductive sheet 132.

[0047] In this embodiment, as a preferred solution, the protrusion mechanism includes at least two shielding plates 120 arranged in a wavy shape along the first direction, which are arranged in sequence in the socket shell 110 along the second direction. The splicing cavity 111 is located between two adjacent shielding plates 120, and the inner wall is provided with a through hole for the protrusion of the shielding plate 120 to pass through. The side surface of the second connecting terminal 210 is at least partially in contact with the protrusion of the shielding plate 120 located in the splicing cavity 111. Through the action of the shielding plate 120, electromagnetic interference can be avoided when the two adjacent first conductive plates 132 and the second conductive plates 212 are conducting or transmitting signals. At the same time, the shielding plate 120 is mostly made of copper plate and has good elasticity and toughness. The shielding plate 120 made of the wavy copper plate material can form a protrusion while shielding electromagnetic interference, which can save space, improve the utilization rate of the overall space, and have higher integration.

[0048] In the present embodiment, as a preferred scheme, the surface of the socket shell 110 is detachably connected to the shielding plate 120 through the provided positioning groove, and the surface of the socket shell 110 is detachably connected to the closing cover 140 through screws, and the closing cover 140 is located above the shielding plate 120 and is used to cover the positioning groove. The shielding plate 120 can be installed or removed through the positioning groove provided in the socket shell 110, which is convenient for disassembly and maintenance of the shielding plate 120 after being used for a period of time. The closing cover 140 is used to cover the positioning groove, and the socket shell 110 and the closing cover 140 are detachable through screws or bolts, which is convenient for subsequent disassembly, replacement or maintenance of the shielding plate 120.
