Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a miniature sunken plate type audio earphone connector. Background Art

[0002] A connector is also called a connector, also known as a joint and a socket. It generally refers to an electrical connector, that is, a device that connects two active devices to transmit current or signals.

[0003] A mini-submerged audio headphone connector is a type of connector that uses a pair of small terminal clamping interfaces to connect it to a device;

[0004] 1. After the interface is inserted and connected, the existing connector completely relies on the connection relationship between the interface and the two terminals to fix the interface, which causes the interface to easily fall off the connector after being slightly pulled, and has poor stability.

[0005] 2. Among the three bending points of the internal terminals of the existing connector, two are at extremely obtuse angles (greater than 120 degrees), resulting in only one bending point having high strength, and the other two bending points being permanently deformed after multiple plug-ins, thus shortening the service life of the device.

[0010] The connector body comprises an interface plugged into a plastic shell, wherein both upper and lower sides of the plastic shell are provided with movable grooves, and one side of the movable groove is provided with a communicating shrinkage groove;

[0011] The fixing assembly comprises a connecting plate welded to the side plate, a movable plate is welded to one end of the connecting plate away from the side plate, a plurality of elastic members are welded to one end of the movable plate close to the connector body, and two movable plates are provided;

[0012] The adapter assembly includes a first terminal and a second terminal connected by bolts at upper and lower sides of the plastic shell, and a first turning point is bent on the first terminal.

[0013] As a preferred solution of the mini sunken audio headphone connector described in the utility model, a mounting groove is opened at one end of the connecting plate away from the movable plate, a fixing plate is bolted in the mounting groove, and the fixing plate is clamped on the outside of the interface on one side close to the interface.

[0014] By adopting the above technical solution, the installation groove is used to provide an installation position for the fixing plate, and the fixing plate is made of the same material as the first terminal and the second terminal, which is copper.

[0015] As a preferred solution of the miniature sunken audio headphone connector described in the utility model, one end of the elastic member away from the movable plate is welded in the shrinkage groove, and the movable plate is movably embedded in the movable groove.

[0016] By adopting the above technical solution, the contraction groove is used to install the elastic member, and the elastic member can bring the movable plate back to its original position after it moves through its own elasticity.

[0017] As a preferred solution of the miniature sunken audio headphone connector described in the utility model, there are two movable grooves, and the two movable grooves are bolted to a fixed block on one side away from each other, and a mating block is welded on the side of the movable plate close to the fixed block.

[0018] By adopting the above technical solution, the fixed block is cylindrical, the embedded block is semicircular, and the embedded block is movably embedded with the fixed block to prevent the movable plate from sliding out of the movable groove.

[0020] By adopting the above technical solution, the engaging groove passes through the fixing block at the side away from the connecting plate, so that the engaging block can be limited while not hindering its movement.

[0021] As a preferred solution of the miniature sunken audio headphone connector described in the utility model, a third turning point is bent at one end of the first terminal away from the first turning point, and a second turning point is bent between the first turning point and the third turning point.

[0022] By adopting the above technical solution, the first turning point, the second turning point and the third turning point are all located on the first terminal and are all formed by bending the first terminal.

[0023] As a preferred solution of the miniature sunken audio headphone connector described in the utility model, the second turning point and the top of the second terminal are against the outer surface of the interface, and one end of the first terminal with a third turning point is tilted away from the second terminal.

[0027] 1. When the interface moves, the fixing plate will be pushed to the side away from itself, so that the fixing plate drives the connecting plate to move, and the connecting plate drives the movable plate at the bottom to move out of the movable groove. During the movement, the engaging block will gradually embed into the top of the fixed block through the track of the engaging groove. When the center of the engaging block coincides with the center of the fixed block, the engaging block can no longer move away from the movable groove. At this time, the two fixing plates will clamp the interface inside. When the interface is taken out, the elastic member will pull the movable plate back to its original position through its own elasticity. Multiple components cooperate with each other to stably clamp the interface on the connector body, thereby improving the stability of the device after connection.

[0028] 2. When the interface is fully inserted into the connector body, the upper and lower ends will be tightly against the second turning point and the top of the second terminal. When one end of the first terminal is tilted, there will still be 0 to 0.05 mm interference contact with the plastic shell, so that the first terminal can still make reliable contact with the second turning point and the interface through contact with the plastic shell after deformation. At the same time, the device with a smooth insertion design reduces the deformation degree of the first terminal and the second terminal during the plugging and unplugging process of the interface, improves the structural strength of the first terminal and the second terminal, and extends the service life of the device.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0038] Example 1

[0039] Reference Figure 1-6 , which is the first embodiment of the utility model, and provides a miniature sink-type audio headset connector, comprising: a connector body 1; fixing components 2 located on both sides of the connector body 1, and the fixing components 2 are used to fix the connection; a switching component 3 located inside the connector body 1, and the switching component 3 is used to connect an external signal;

[0040] Specifically, the connector body 1 includes an interface 102 plugged into a plastic shell 101, and movable grooves 103 are provided on both upper and lower sides of the plastic shell 101, and a connecting shrinkage groove 104 is provided on one side of the movable groove 103;

[0041] The fixing assembly 2 includes a connecting plate 202 welded to the side plate 201, a movable plate 203 is welded to one end of the connecting plate 202 away from the side plate 201, and a plurality of elastic members 206 are welded to one end of the movable plate 203 close to the connector body 1, and two movable plates 203 are provided;

[0042] The adapter assembly 3 includes a first terminal 301 and a second terminal 305 connected to the upper and lower sides of the plastic shell 101 by bolts, and a first turning point 302 is bent on the first terminal 301 .

[0043] Furthermore, when the interface 102 moves, the fixing plate 204 will be pushed to the side away from itself, so that the fixing plate 204 drives the connecting plate 202 to move, and the connecting plate 202 drives the movable plate 203 at the bottom to move out of the movable groove 103. During the movement, the engaging block 207 will gradually embed into the top of the fixing block 208 through the trajectory of the engaging groove 209. When the center of the engaging block 207 coincides with the center of the fixing block 208, the engaging block 207 can no longer move away from the movable groove 103. At this time, the two fixing plates 204 will clamp the interface 102 inside. When the interface 102 is taken out, the elastic member 206 will pull the movable plate 203 back to its original position through its own elasticity. Multiple components cooperate with each other to stably clamp the interface 102 on the connector body 1, thereby improving the stability of the device after connection.

[0044] Example 2

[0045] Reference Figure 2 and Figure 4-6 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0046] Specifically, an installation groove 205 is formed at one end of the connecting plate 202 away from the movable plate 203, and a fixing plate 204 is bolted in the installation groove 205. The side of the fixing plate 204 close to the interface 102 is clamped on the outside of the interface 102, and the end of the elastic member 206 away from the movable plate 203 is welded in the shrinkage groove 104, and the movable plate 203 is movably engaged in the movable groove 103. There are two movable grooves 103, and a fixing block 208 is bolted on one side of the two movable grooves 103 away from each other. An engaging block 207 is welded on one side of the movable plate 203 close to the fixed block 208, and an engaging groove 209 is formed on the side of the fixed block 208 close to the engaging block 207, and one side of the engaging groove 209 passes through the fixed block 208, and the engaging block 207 is movably engaged in the engaging groove 209.

[0047] Furthermore, the mounting groove 205 is used to provide an installation position for the fixing plate 204. The fixing plate 204 is made of the same material as the first terminal 301 and the second terminal 305, all of which are made of copper. The shrinkage groove 104 is used to install the elastic member 206. The elastic member 206 can bring the movable plate 203 back to its original position after the movable plate 203 moves through its own elasticity; the fixed block 208 is cylindrical, and the engaging block 207 is semicircular. The engaging block 207 is movably engaged with the fixed block 208 to prevent the movable plate 203 from slipping out of the movable groove 103. The engaging groove 209 passes through the fixed block 208 on the side away from the connecting plate 202, so as to limit the movement of the engaging block 207 without hindering it.

[0048] Example 3

[0049] Reference Figure 2 and Figure 3 , which is the third embodiment of the utility model, and this embodiment is based on the first embodiment.

[0050] Specifically, the end of the first terminal 301 away from the first turning point 302 is bent to have a third turning point 304, and the second turning point 303 is bent between the first turning point 302 and the third turning point 304. The second turning point 303 and the top of the second terminal 305 are against the outer surface of the interface 102, and the end of the first terminal 301 with the third turning point 304 is tilted away from the second terminal 305.

[0051] Furthermore, the first turning point 302, the second turning point 303 and the third turning point 304 are all located on the first terminal 301 and are all formed by bending the first terminal 301. The first turning point 302 is in a semicircular shape, and the second turning point 303 and the third turning point 304 are two obtuse angles facing opposite directions. When one end of the first terminal 301 is tilted, there will still be an interference of 0 to 0.05 mm with the plastic shell 101, so that the first terminal 301 can still contact with the interface 102 after deformation.

[0052] Working principle: Insert the interface 102 into the plastic shell 101. When the interface 102 moves, the first terminal 301 and the second terminal 305 will be squeezed in the direction away from each other. The first terminal 301 will move the end with the third turning point 304 toward the top inner wall of the plastic shell 101 through the first turning point 302. When the interface 102 is fully connected to the connector body 1, the upper and lower ends will be tightly against the second turning point 303 and the top of the second terminal 305. When the interface 102 moves, it will push the fixing plate 204 away from itself, so that the fixing plate 204 drives the connecting plate 202 to move, and the connecting plate 202 drives the bottom movable plate 203 from the movable plate 203. When the movable plate 203 is moved out of the groove 103, since an elastic member 206 is connected to one side of the movable plate 203, the movable plate 203 will pull the elastic member 206 when it moves, and the engaging block 207 will gradually embed into the top of the fixed block 208 through the trajectory of the engaging groove 209 during the movement. Since the engaging groove 209 only passes through the fixed block 208 on the side away from the connecting plate 202, when the center of the engaging block 207 coincides with the center of the fixed block 208, the engaging block 207 can no longer move in the direction away from the movable groove 103. At this time, the two fixing plates 204 will clamp the interface 102 inside. When the interface 102 is taken out, the elastic member 206 will pull the movable plate 203 back to its original position through its own elasticity.
