The plug 100 and the socket 200 use their head ends as the plug-in ends respectively, that is, the head end of the plug 100 is plugged with the head end of the socket 200, and the tail of the plug 100 can be connected with a tail clip and a shielded cable. The socket 200 is installed on the box body.
[0023] The plug 100 includes a plug housing 101. The plug housing 101 is equipped with a first plug mounting plate 131, a second plug mounting plate 121, a jack contact 111 and a plug snap ring 141. The plug housing 101 is made of aluminum alloy. Both the plug mounting plate 131 and the second plug mounting plate 121 are made of hard plastic, and the jack contacts 111 are made of copper alloy, and the surface is plated with hard gold to reduce contact resistance; There is a plug connection plate 102 on the outer wall of the body 101 near the tail end, and a plug mounting hole 103 is provided on the plug connection plate 102. A sleeve 104 and a gasket 105 are installed in the plug mounting hole 103. The sleeve 104 is also made of aluminum alloy. 104 can float freely, which is convenient to change the angle of the plug 100 when plugging the plug 100 into the socket 200; there is a first stepped surface 106 on the inner wall of the plug housing 101, and the outer wall surface of the first plug mounting plate 131 is provided with the first stepped surface. The second stepped surface 132 opposite to the stepped surface 106, when the first plug mounting plate 131 is installed in the plug housing 101, the second stepped surface 132 abuts against the first stepped surface 106, which acts as a limiter and prevents the second A plug mounting plate 131 falls out from the plug housing 101; the first plug mounting plate 131 has thirteen first stepped holes for the jack contacts to pass through, and the head of the jack contacts 111 has a pin contact The socket 112 that the probe 211c of the piece 211 is inserted into, the socket contact 111 is installed in the first stepped hole, the middle part of the socket contact 111 has an annular protrusion 113, and the annular protrusion 113 is stuck in the first stepped hole, thereby Restrict jack contacts 111 from moving toward the head end of plug housing 101; there are thirteen first circular holes for jack contacts 111 to pass through on the second plug mounting plate 121, and the other end of jack contacts 111 from Pass through the first round hole, the inner diameter of the first round hole is smaller than the outer diameter of the annular projection 113, thereby limiting the movement of the socket contact 111 to the tail end of the plug housing 101; there is a second hole on the inner wall of the socket housing 101 near the tail end. A U-shaped groove 107, the first U-shaped groove 107 has a plug snap ring 141, the plug snap ring 141 protrudes from the first U-shaped groove 107, and can prevent the second plug mounting plate 121 from slipping out of the plug housing 101 .
[0024] The socket 200 includes a socket housing 201. The socket housing 201 is equipped with a first socket mounting plate 231, a second socket mounting plate 221, pin contacts 211, a socket snap ring 241 and a gasket 251. The socket housing 201 is made of aluminum alloy Material, the first socket mounting plate 231 and the second socket mounting plate 221 are all hard plastics, and the material of the gasket 251 is soft silicon rubber; the head end of the socket housing 201 outer wall has a socket connecting plate 202, and the socket connecting plate 202 There is a socket mounting hole 203 on the top to facilitate fixing the socket 200 on the box body; the head end of the socket housing 201 is a horn hole 204, and the tail end is a round hole 205, and the horn hole 204 and the round hole 205 are connected by a convex ring 206, The tail end of the horn hole 204 is connected with a convex ring 206, and the inner diameter of the convex ring 206 is the same as the inner diameter of the tail end of the horn hole 204; there is a second U-shaped groove 207 at the junction of the inner wall of the round hole 205 and the convex ring 206, and the second U-shaped groove 207 There is a sealing gasket 251 inside, and the sealing gasket 251 has thirteen holes for the pin contacts to pass through; the inner wall of the round hole 205 of the socket housing 201 is close to the second U-shaped groove 207. The shoulder 208, the first socket mounting plate 231 is installed in the round hole 205 of the socket housing 201, and its position is defined by the shoulder 208. The first socket mounting plate 231 has a hole for the pin contact to penetrate. In the second stepped hole, the pin contact 211 is inserted into the second stepped hole, and the annular boss 212 in the middle of the pin contact 211 abuts against the stepped surface of the second stepped hole, thereby defining the position of the pin contact 211 , the probe 213 of the pin contact 211 passes through the hole of the sealing gasket 251, and extends into the horn hole 204; the second socket mounting plate 221 is put into the round hole 205 of the socket housing 201, The second socket mounting plate 221 also has thirteen second round holes for the pin contacts to pass through. The other side is against the end face of the second socket mounting plate 221; the round hole 205 inner wall of the socket housing 201 has a third U-shaped groove 209 near the tail end, and a socket snap ring 241 is installed in the third U-shaped groove 209, and the socket snap ring The ring 241 protrudes from the third U-shaped groove 209 to prevent the second socket mounting plate 221 from falling out of the socket housing 201 .
[0025]Described pin contact 211 is made up of binding post 214, spring 215 and probe 213, and binding post 215, spring 215 and probe 213 are surface gold-plated, and reduces the contact resistance of contact; The counterbore is equipped with a spring 212 and a probe 213. The spring 215 is located between the end of the probe 213 and the end face of the counterbore. The head end of the counterbore is closed to prevent the probe 213 from falling out. , the probe 213 will be compressed, so that the probe 213 has a certain contact pressure with the socket contact 111 to ensure reliable contact, even if it is inserted obliquely, the contact reliability can be guaranteed.
[0026] During normal mating, the central axis of the plug 100 and the central axis of the socket 200 are collinear, such as Figure 7 As shown, the probe 213 of the pin contact 211 is directly aligned with the socket 112 of the socket contact 111 , and the probe 213 is inserted into the socket 112 , so that the plug 100 is mated with the socket 200 .
[0027] If the central axis of the plug 100 and the central axis of the socket 200 form an included angle less than 30° when mating (that is, oblique insertion), such as Figure 8 As shown, because the socket 200 is generally fixed on the box body, the plug 100 is generally connected with the tail clip and the shielded cable, and the head end of the plug 100 is obliquely inserted into the horn hole 204 at the head end of the socket 200. Since the sleeve 104 can float freely, Make the central axis of the plug housing 101 no longer parallel to the central axis of the sleeve 104, but form a certain angle to facilitate the connection between the plug 100 and the socket 200. When continuing to insert, the first part of the plug 100 enters the convex ring 206 first, and Transitionally cooperate with the protruding ring 206, so that the plug 100 can be automatically aligned, thereby adjusting the angle of the plug 100, and automatically adjusting from the inclined insertion state to the horizontal insertion state; when the insertion is continued, the probe 213 of the pin contact 211 is inserted into the socket for contact In the socket 112 of the component 111, due to the oblique insertion, the probe 213 will be squeezed into the counterbore of the terminal 214, and when the insertion is completed, the probe 213 will always keep in contact with the socket under the action of the spring 215 The end face pressure of the piece 111 ensures the reliability of the contact.
[0028] The foregoing is only a specific embodiment of the present invention, and is not a limitation of the present invention. Any changes or modifications made by those skilled in the art using the above technical content shall be regarded as Belong to the protection scope of the present invention.
