Plug-in interface assembly

Abstract

The plug-in interface assembly comprises a fixed seat and a plug-in piece. The fixed seat comprises a base, a connecting piece and a gold finger. The base comprises a socket, a first through hole and a second through hole, both of which are communicated with the socket. The connecting piece comprises a first fixed end and a first free end. The gold finger comprises a second fixed end and a second free end. The first free end extends from the first through hole to the socket, and the second free end extends from the second through hole to the socket. The connecting piece and the gold finger are insulatedly connected. The first free end is closer to the opening side of the socket than the second free end. The plug-in piece is used for being inserted into the socket. The plug-in piece comprises a groove and an electrical connecting part. When the plug-in piece is inserted into the socket, the plug-in piece preferentially abuts against the first free end, so that the connecting piece drives the gold finger to synchronously deform and is accommodated in the second through hole. When the plug-in piece is further inserted into a preset position, the first free end is located in the groove and rebounds, the gold finger rebounds synchronously with the connecting piece, and the second free end abuts against the electrical connecting part.

Description

Technical Field

[0001] This application relates to the field of mechanical technology, and more particularly to a pluggable interface component. Background Technology

[0002] In the field of electronic devices, charging interfaces and data interfaces for 3C products are widely used as core components for power transmission and data interaction. However, during long-term use, these interfaces need to be frequently plugged and unplugged to meet usage needs. This process inevitably causes the electroplating layer (such as the commonly used gold layer) on the interface contact area to gradually wear away. At the same time, when the electroplating layer wears away and the circuit layer is exposed to air, it is prone to oxidation, leading to increased contact resistance. Ultimately, this can cause poor interface contact or even complete lack of conductivity, seriously affecting the normal function of the device and the user experience. Utility Model Content

[0003] In view of this, it is necessary to provide a pluggable interface component that improves interface friction during the plugging process in order to solve the above problems.

[0004] A pluggable interface assembly includes a mounting base and a connector. The mounting base includes a base, a connector, and gold fingers. The base includes a socket, a first through hole, and a second through hole, both of which communicate with the socket. The connector includes a first fixed end and a first free end. The gold fingers include a second fixed end and a second free end. The first fixed end is fixed to the base, and the first free end extends from the first through hole to the socket. The second fixed end is fixed to the base, and the second free end extends from the second through hole to the socket. The connector and the gold fingers are insulated from each other, and the first free end is closer to the opening of the socket than the second free end. The connector is for insertion into the socket. The connector includes a groove and an electrical connection portion. When the connector is not inserted into the socket, the first free end protrudes into the socket, and the second free end protrudes into the socket. When the connector is inserted into the socket, the connector preferentially abuts against the first free end, causing the connector to drive the gold finger to deform synchronously and be received in the second through hole. When the connector is further inserted into a preset position, the first free end is located in the groove and rebounds. The gold finger rebounds synchronously with the connector, and the second free end abuts against the electrical connection portion.

[0005] In some possible embodiments of this application, the mounting base further includes a circuit board, the base further includes a receiving cavity, the circuit board is located in the receiving cavity, the gold finger further includes an electrical connection terminal, the electrical connection terminal is located on the side of the second fixed end opposite to the second free end, and the electrical connection terminal is electrically connected to the circuit board.

[0006] In some possible embodiments of this application, the connector includes a first elastic portion, a second elastic portion, and a crossbeam. The first elastic portion and the second elastic portion each include a first fixed end and a first free end. The first elastic portion and the second elastic portion are located on both sides of the gold finger. The crossbeam connects the first elastic portion and the second elastic portion and is insulated from the gold finger.

[0007] In some possible embodiments of this application, the base further includes a third through hole that connects the first through hole and the insertion hole; the third through hole is used to accommodate the crossbeam.

[0008] In some possible embodiments of this application, the third through hole is located on the side of the first through hole away from the opening side.

[0009] In some possible embodiments of this application, the number of gold fingers is multiple, and the crossbeam is connected to each of the gold fingers.

[0010] In some possible embodiments of this application, the pluggable interface assembly further includes an insulating layer located between the crossbeam and the gold fingers, the insulating layer serving to insulate the connection between the crossbeam and the gold fingers.

[0011] In some possible embodiments of this application, the connector is made of metal or a metal alloy.

[0012] In some possible embodiments of this application, the base further includes a first slot and a second slot, the first slot being connected to the first through hole, the second slot being connected to the second through hole, the first fixed end being held in the first slot, and the second fixed end being held in the second slot.

[0013] In some possible embodiments of this application, when the connector is not inserted into the socket, the height of the first free end in the socket is higher than the height of the second free end in the socket.

[0014] During the insertion and removal processes of the connector, the connector slides relative to the connector, while there is a gap between the gold finger and the connector. That is, the gold finger and the connector do not slide relative to each other, thereby improving the problem of poor contact or conductivity caused by wear between the gold finger and the connector, extending the service life of the pluggable interface assembly and improving the user experience.

[0027] Please see Figure 1 and Figure 2 The pluggable interface assembly 100 includes a fixed base 10 and a connector 20. The connector 20 is detachably plugged into the fixed base 10 and interconnected. Figure 1 This is a schematic diagram showing the structure of the connector 20 not being inserted into the fixing base 10. Figure 2 This is a schematic diagram of the structure in which the connector 20 is inserted into the fixed base 10.

[0028] Please see Figure 3 , Figure 4 and Figure 5 The mounting base 10 may include a base 11, a connector 12, a gold finger 13, and a circuit board 14. Both the connector 12 and the gold finger 13 are connected to the base 11. The connector 12 is insulated from the circuit board 14, and the gold finger 13 is electrically connected to the circuit board 14. When the connector 20 is inserted into the mounting base 10, the gold finger 13 serves to electrically connect to the connector 20. The connector 12 is also insulated from the gold finger 13. During the insertion or removal of the connector 20 from the mounting base 10, the gold finger 13 and the connector 12 move synchronously to prevent slippage between them, thereby protecting the gold finger 13.

[0029] The base 11 may include a socket 111, a first through hole 112, and a second through hole 113, both of which communicate with the socket 111. The base 11 may also include a first slot 115 and a second slot 116, with the first through hole 112 connecting the first slot 115 and the socket 111, and the second through hole 113 connecting the second slot 116 and the socket 111. The base 11 may also include a receiving cavity 117, with both the first through hole 112 and the second through hole 113 communicating with the receiving cavity 117, and the circuit board 14 located within the receiving cavity 117.

[0030] The connector 12 includes a first fixed end 121 and a first free end 122. Both the first fixed end 121 and the first free end 122 can be end regions of the connector 12. The first fixed end 121 is used to fix to the base 11, and the first free end 122 is used to move relative to the first fixed end 121. In this embodiment, the first fixed end 121 is engaged in the first slot 115 to achieve mutual fixation between the first fixed end 121 and the base 11; the first free end 122 passes through the first through hole 112 and is used to extend towards the insertion hole 111.

[0031] The gold finger 13 includes a second fixed end 131 and a second free end 132. The second fixed end 131 and the second free end 132 can be the end regions of the gold finger 13. The second fixed end 131 is used to fix it to the base 11, and the second free end 132 is used to move relative to the second fixed end 131. In this embodiment, the second fixed end 131 is engaged in the second slot 116 to achieve mutual fixation between the second fixed end 131 and the base 11; the second free end 132 passes through the second through hole 113 and is used to extend towards the insertion hole 111.

[0032] The gold finger 13 also includes an electrical connection terminal 133, which is located on the side of the second fixed end 131 away from the second free end 132, and the electrical connection terminal 133 is electrically connected to the circuit board 14.

[0033] The socket 111 has an open side, meaning that when the connector 20 is inserted into the fixing base 10, the connector 20 enters the socket 111 from the open side. The connector 12 is connected to the gold finger 13, and the first free end 122 is closer to the open side of the socket 111 than the second free end 132.

[0034] The connector 20 is used to insert into the socket 111. The connector 20 includes a groove 21 and an electrical connection portion 22. The connector 20 is formed by a recess on its surface. The groove 21 is used to receive the first free end 122. The electrical connection portion 22 is located on the surface of the connector 20 and is used to connect with the second free end 132 to realize the electrical connection between the connector 20 and the fixing base 10.

[0035] When the connector 20 is not inserted into the fixing base 10, the first free end 122 protrudes into the insertion hole 111, and the second free end 132 protrudes into the insertion hole 111.

[0036] Please see Figure 6 When the connector 20 is inserted into the socket 111, since the first free end 122 is closer to the opening side of the socket 111 than the second free end 132, the connector 20 preferentially abuts against the first free end 122, causing the connector 12 to drive the gold finger 13 to deform synchronously and be received in the second through hole 113. That is, the first free end 122 and the connector 20 slide relative to each other, and the second free end 132 does not contact the connector 20, and there is a gap between the second free end 132 and the connector 20. When the connector 20 is further inserted into the preset position, the first free end 122 is located in the groove 21 and rebounds, the gold finger 13 rebounds synchronously with the connector 12, and the second free end 132 abuts against the electrical connection part 22.

[0037] When the connector 20 is pulled out of the socket 111, the first free end 122 abuts against the side wall of the groove 21 and deforms until the first free end 122 exits from the groove 21. At this point, the first free end 122 abuts against the surface of the connector 20, and the deformation of the connector 12 is at its maximum. During this process, the connector 12 drives the gold finger 13 to deform synchronously, and there is a gap between the gold finger 13 and the connector 20. When the connector 20 is further pulled out of the socket 111, until the first free end 122 separates from the surface of the connector 20, the first free end 122 is located in the socket 111 and springs back. The gold finger 13 springs back synchronously with the connector 12, and the second free end 132 is located in the socket 111.

[0038] During the insertion and removal processes of the connector 20, the connector 12 slides relative to the connector 20, and there is a gap between the gold finger 13 and the connector 20. That is, the gold finger 13 and the connector 20 do not slide relative to each other, thereby improving the problem of poor contact or conductivity caused by wear between the gold finger 13 and the connector 20, and improving the service life of the pluggable interface assembly 100 and the user experience.

[0039] When the connector 20 is not inserted into the socket 111, the height of the first free end 122 in the socket 111 is higher than the height of the second free end 132 in the socket 111. This ensures that when the connector 20 is in the socket 111 and the first free end 122 is not in the groove 21, there is a sufficient gap between the second free end 132 and the connector 20, and the second free end 132 and the connector 20 slide relative to each other.

[0040] The connector 12 may further include a first elastic portion 123, a second elastic portion 124, and a crossbeam 125. Both the first elastic portion 123 and the second elastic portion 124 include a first fixed end 121 and a first free end 122. The first elastic portion 123 and the second elastic portion 124 are located on both sides of the gold finger 13. Two first through holes 112 are included, located on both sides of the second through hole 113, with one first through hole 112 for the corresponding first elastic portion 123 to pass through. The crossbeam 125 connects the first elastic portion 123 and the second elastic portion 124, and the crossbeam 125 is also used for insulated connection with the middle region of the gold finger 13, thereby enabling the gold finger 13 to move synchronously with the connector 12.

[0041] The first elastic portion 123 and the second elastic portion 124 are located at both ends of the gold finger 13, which helps to maintain the movement stability of the gold finger 13. Multiple gold fingers 13 are included, and the crossbeam 125 is connected to the middle region of each gold finger 13, which can maintain the movement consistency of the multiple gold fingers 13.

[0042] The connector 12 can be made of metal or a metal alloy. Metal or metal alloy materials can withstand multiple deformations, thereby extending the service life of the connector 12. The pluggable interface assembly 100 may also include an insulating layer 15 located between the crossbeam 125 and the gold finger 13. The insulating layer 15 serves to insulate the connection between the crossbeam 125 and the gold finger 13.

[0043] The base 11 also includes a third through hole 114, which connects the first through hole 112 and the insertion hole 111, and is used to accommodate the crossbeam 125. When the connector 20 is not inserted into the socket 111, the crossbeam 125 is located in the third through hole 114. When the connector 20 is inserted into the socket 111, the first free end 122 is abutted by the connector 20 toward the first through hole 112 and the receiving cavity 117. The crossbeam 125 moves toward the receiving cavity 117 synchronously with the first elastic part 123 and the second elastic part 124, thereby driving the gold finger 13 to move toward the second through hole 113 and the receiving cavity 117. When the first free end 122 corresponds to the groove 21 of the connector 20 and is located in the groove 21, the first elastic part 123 and the second elastic part 124 both rebound, and the crossbeam 125 rebounds synchronously, thereby driving the gold finger 13 to rebound synchronously and abut against the electrical connection part 22 of the connector 20.

[0044] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the scope of the technical solutions of this application.
