Description

TECHNICAL FIELD

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

[0002] The connector is an electrical component for connecting circuits, mainly used in the fields of aviation, aerospace, medical treatment, military equipment, etc. The electrical connector can make the circuit connection simpler and more reliable, and is widely used.

[0003] The existing connector will deviate within a certain range when in use, which will cause the plug-in of the connector to fail. SUMMARY

[0004] Therefore, the present application provides a connector which can accommodate the deviation caused by long-term use of the equipment and ensure normal plugging without any damage to the connector.

[0005] According to an aspect of the present application, a connector is provided, which comprises a plug and a socket used in cooperation with each other.

[0006] The side wall of the plug is provided with a pin, and the side wall of the socket is provided with a contact surface. The contact surface is made of conductive material, and the number of the contact surfaces matches the number of the pins.

[0007] When the plug and the socket are electrically connected, the side wall of the plug provided with the pin is arranged opposite to the side wall of the socket provided with the contact surface, and the pin and the contact surface correspondingly abut.

[0008] The area of the contact surface is greater than the area of the end surface of the pin.

[0009] In a possible implementation, the pin and the contact surface are both provided with two or more than two, and one-to-one correspondence.

[0010] The distance is provided between each two adjacent contact surfaces.

[0011] In a possible implementation, when the plug and the socket are electrically connected, the pin abuts at the center position of the corresponding contact surface.

[0012] In a possible implementation, the area of the contact surface is more than three times the area of the end surface of the pin.

[0013] In a possible implementation, the contact surface is realized by installing a conductive sheet on the side wall of the socket.

[0014] The side wall of the socket is provided with a mounting groove, and the structure of the mounting groove is the same as that of the conductive sheet.

[0015] In a possible implementation, the plug is provided with a protective ring, the protective ring is annularly arranged, and the protective ring is arranged circumferentially around the outer side of the plug pin.

[0016] When the socket and the plug are electrically connected, the protective ring abuts against the side wall of the socket, and the contact surface is located inside the protective ring.

[0017] In a possible implementation, the protective ring is an elastic protective ring, and the protective ring is provided with a groove.

[0018] The groove is circumferentially arranged around the outer wall of the protective ring.

[0019] In a possible implementation, the protective ring is a rubber piece, and the groove is arranged at the middle position of the outer wall of the protective ring.

[0020] In a possible implementation, the conductive sheet is a circular sheet, and the slot of the mounting groove is circularly arranged.

[0021] The conductive sheet is flush with the slot of the mounting groove on one side of the slot.

[0022] In a possible implementation, two or more plug pins are uniformly distributed along the length direction of the end surface of the plug pin on one side of the plug.

[0023] Two or more contact surfaces are uniformly distributed along the length direction of the side surface of the contact surface on one side of the socket.

[0024] The area of the contact surface is greater than or equal to three times the area of the end surface of the plug pin and less than or equal to six times the area of the end surface of the plug pin.

[0025] The connector of the embodiment of the present application is provided with a plug and a socket, and the plug and the socket are electrically connected when in use. At this time, the plug pin and the contact surface abut against each other, and each contact surface contacts one plug pin. Since the area of the contact surface is greater than the area of the end surface of the plug pin, there is a margin when the contact surface and the plug pin abut against each other. When the plug pin deviates due to too many times of plug-in of the plug and the socket or due to installation of the plug and the socket, the contact surface can also abut against the plug pin, thereby ensuring normal plug-in of the plug and the plug pin. Therefore, the connector of the embodiment of the present application can accept deviation of the plug pin within a certain range, especially can accommodate deviation due to long-term use of equipment, and ensures normal plug-in without any damage to the connector.

[0040] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0041] Figure 1 This diagram shows the main structure of the connector plug 100 according to an embodiment of this application. Figure 2 This diagram illustrates the main structural structure of the connector socket 200 according to an embodiment of this application. Figure 1 or Figure 2 As shown, the connector includes a socket 200 and a plug 100 that cooperate with each other. The socket 200 has pins 300 on its first sidewall and contact surfaces 400 on its first sidewall. The contact surfaces 400 are made of a conductive material to enable electrical connection between the plug 100 and the socket 200. The number of contact surfaces 400 matches the number of pins 300. When the socket 200 and pins 300 are plugged in for electrical connection, the first sidewalls of the plug 100 and the socket 200 are positioned opposite each other, and the pins 300 and contact surfaces 400 abut against each other. The area of ​​the contact surfaces 400 is larger than the end face area of ​​the pins 300.

[0042] The connector in this embodiment includes a plug 100 and a socket 200. During use, the plug 100 and socket 200 are electrically connected. At this time, pins 300 abut against contact surfaces 400, and each contact surface 400 has one pin 300 in contact with it. Since the area of ​​the contact surface 400 is larger than the area of ​​the end face of the pin 300, there is a margin when the contact surface 400 abuts against the pin 300. Even if the pin 300 shifts due to excessive insertions and insertions of the plug 100 and socket 200, or due to improper installation, the contact surface 400 can still abut against the pin 300, thus ensuring normal insertion of the plug 100 and pin 300. Therefore, the connector in this embodiment can accept pin 300 shifting within a certain range, especially accommodating the inevitable shifting that occurs during long-term use of the device, ensuring normal insertion without damaging the connector.

[0043] In one possible implementation, the plug 100 and the socket 200 are rotatably connected to electrically connect or disconnect the plug 100 and the socket 200.

[0044] In one possible implementation, there are two or more contact surfaces 400, with a distance between adjacent contact surfaces 400. It should be noted that there are also two or more pins 300 corresponding to the contact surfaces 400, and the number of pins 300 is the same as the number of contact surfaces 400.

[0045] The connector in this embodiment of the application has a rotatable plug 100 and a socket 200. The socket 200 can be fixed to rotate the plug 100. The pins 300 on the plug 100 gradually approach the contact surfaces 400 on the socket 200 until the pins 300 and the contact surfaces 400 abut against each other. Each contact surface 400 is in contact with a pin 300, thereby completing the electrical connection between the plug 100 and the socket 200.

[0046] Furthermore, in one possible implementation, the plug 100 and the socket 200 can be hinged. It should be noted that, in one possible implementation, the plug 100 and the socket 200 can be hinged via a damping pivot. This damping pivot ensures that the plug 100 and the socket 200 will not separate after insertion without external force. In one possible implementation, when the plug 100 and the socket 200 are electrically connected, the pin 300 is located at the center of the corresponding contact surface 400, and two or more contact surfaces 400 are arranged in an array. In the present application embodiment, when the connector is in use (i.e., the plug 100 and the socket 200 are electrically connected), the pin 300 being located at the center of the contact surface 400 is the optimal position, allowing the contact surface 400, with a fixed area, to accept the offset of the pin 300 in different directions, and the offset in different directions should be as large as possible.

[0047] It should be noted here that, in one possible implementation, the corresponding two or more pins 300 are also arrayed. It should also be noted here that the array of contact surfaces 400 can be an equally spaced array or an unequally spaced array; no limitation is made here.

[0048] In one possible implementation, the area of ​​the contact surface 400 is more than three times the area of ​​the end face of the pin 300. It should also be noted that, where structurally permissible, the area of ​​the contact surface 400 can be as large as possible, as long as adjacent contact surfaces 400 do not contact each other.

[0049] In one possible implementation, the contact surface 400 is implemented by mounting a conductive sheet on the side wall of the socket 200. The first side wall of the socket 200 has a mounting groove with the same structure as the conductive sheet, and the conductive sheet is welded into the mounting groove.

[0050] Furthermore, in one possible implementation, the conductive sheet can be circular, the opening of the mounting groove is circular, and the side of the conductive sheet facing the opening of the mounting groove is flush with the opening of the mounting groove. It should be noted that the side of the conductive sheet facing the opening of the mounting groove can also be located inside the mounting groove and adjacent to the opening of the mounting groove.

[0051] The installation slot allows the conductive sheet to be placed inside, making the connection of the conductive sheet more secure and reducing the thickness of the socket 200.

[0052] Furthermore, in one possible implementation, a rectangular placement groove is formed on the first side wall of the socket 200, and a placement plate with placement grooves is welded inside the groove. This further facilitates the placement of the conductive sheet and reduces the manufacturing difficulty of the socket 200.

[0053] It should also be noted here that, in one possible implementation, the conductive sheet can be directly fixed to the first side wall of the socket 200 by welding, or it can be fixed to the socket 200 by other means, such as by printing and electrically connecting it to the power-carrying wire of the socket 200. This will not be elaborated here.

[0054] In one possible implementation of the connector, the plug 100 has a protective ring 500, which is annular and circumferentially surrounds the outer side of the pin 300. When the socket 200 and the plug 100 are electrically connected, the protective ring 500 abuts against the side wall of the socket 200, and the contact surface 400 is located inside the protective ring 500.

[0055] It should be noted here that, in one possible implementation, when there are two or more pins 300, the protective ring 500 is arranged circumferentially around the two or more pins 300, so that all pins 300 are located within the space enclosed by the protective ring 500. When the plug 100 and the socket 200 are plugged in, the protective ring 500 abuts against the socket 200, and the contact surfaces 400 are all located within the space enclosed by the protective ring 500. Therefore, when the connector in this embodiment is in the closed (electrically connected) state, the protective ring 500 can provide waterproofing, preventing the contact surfaces 400 and pins 300 from getting damp.

[0056] In one possible implementation, the protective ring 500 is an elastic protective ring 500, with a groove formed on it, circumferentially surrounding the outer wall of the protective ring 500. Therefore, the groove allows it to withstand greater compression and deformation, ensuring a waterproof effect even under certain deformation.

[0057] Furthermore, in one possible implementation, the protective ring 500 is a rubber component, with the groove located at the center of its outer surface. This optimizes the structure of the protective ring 500 and ensures the thickness on both sides of the groove.

[0058] Furthermore, in one possible implementation, the protective ring 500 has an adsorption part on the end facing away from the plug 100. The adsorption part can be a suction cup structure and is arranged around the circumference of the protective ring 500 so that the protective ring 500 can fit tightly against the socket 200 through the adsorption part. This can further achieve a sealing and waterproofing function.

[0059] In one possible implementation, two or more pins 300 are evenly spaced along the length of the first sidewall of the plug 100, and two or more contact surfaces 400 are also spaced along the length of the first sidewall of the socket 200. The area of ​​the contact surface 400 is greater than or equal to three times the end face area of ​​the pin 300, or less than or equal to six times the end face area of ​​the pin 300.

[0060] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 or Figure 8 As shown, it should also be noted that in one possible implementation, the plug 100 can be an irregularly shaped plug 100, including a plug head 110 and a plug tail 120. The plug head 110 is rectangular, and its first sidewall has two or more pins 300. The plug tail 120 is fixedly mounted on the third sidewall of the plug head 110, with the third sidewall of the plug head 110 opposite to its first sidewall. The plug tail 100 is connected to the plug head 110 at an obtuse angle, and the connection between the plug head 110 and the plug tail 120 uses a curved transition. A first through groove is formed at the bottom of the plug tail 120 on the side away from the plug head 110, extending along the width of the plug tail 120, and the top of the first through groove is arc-shaped. The plug head 110 has a first blind hole and a second blind hole at its top. The first blind hole is located adjacent to the second sidewall of the plug head 110, and the second blind hole is located adjacent to the fourth sidewall of the plug head 110. The first, second, third, and fourth sidewalls of the plug head 110 form a rectangular frame. A first through hole 111 is located at the bottom of the first blind hole, and a second through hole 112 is located at the bottom of the second blind hole. The top of the plug 100 tail, on the side away from the plug head 110, has a first chamfer and a second chamfer, located at the two feet of the plug 100 tail on the side away from the plug head 110, respectively. A third through hole 121 is located at the bottom of the first chamfer, and a fourth through hole 122 is located at the bottom of the second chamfer. The first through hole 111, the second through hole 112, the third through hole 121, and the fourth through hole 122 are used for connection to external components via bolts. The protective ring 500 is disposed on the first side wall of the plug head 110, and the pin 300 is located in the area enclosed by the protective ring 500.

[0061] It should also be noted that, in one possible implementation, the socket 200 is box-shaped, with its first and third sidewalls both trapezoidal, and its second and fourth sidewalls obtuse-angled, with the obtuse angles bending downwards. The first, second, third, and fourth sidewalls of the socket 200 form a frame. The top of the socket 200 has a third and a fourth blind hole, respectively, located adjacent to the second and fourth sidewalls. The bottom of the third blind hole has a fifth through hole 210, and the bottom of the fourth blind hole has a sixth through hole 220. The fifth and sixth through holes 210 and 220 are used for bolts to connect to external components.
