Detailed ways

The technical solution of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention. Where reference is made to the figures, the same numbers in the figures represent the same or similar elements. The described embodiments are only some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in Figures 1-8, an easily detachable sealed connector with enhanced stability includes a socket and a plug, both of which are provided with a housing 1 and a base 2, wherein the base 2 is provided with pins 7 or The socket 4, a sealing layer 5 is provided between the rear end of the base 2 and the shell 1, the socket shell 1 is provided with a flange fixing plate, and the flange fixing plate is provided with a flange sealing ring 12; The base 2 is provided with two pairs of differential components 8 and multiple pairs of single-core components, and the differential components 8 are arranged in the middle position; The rear end of the plug housing 1 is connected with a movable tail cover 9 , the middle of the tail cover 9 is provided with an annular clip slot 13 , and the rear end of the tail cover 9 is provided with a symmetrical clip 14 . The connector can be connected and disconnected through the socket and plug. The sealing layer 5 is sealed with glue, and the sealing layer 5 can ensure the airtightness between the shell 1, the base 2 and the wires. After the socket and the plug are connected, the contact surface can be kept airtight by the flange sealing ring 12, so as to improve the sealing performance. Connector waterproof performance. Two pairs of differential components 8 and multiple pairs of single-core components provide the connection requirements for high-speed digital signals and control signals, and the differential components 8 are located in the middle and are less susceptible to external interference.

The socket of the connector is fixedly installed, and the plug is clamped and fixed by the annular slot 13 on the tail cover 9. Before the connector is disengaged, it is necessary to control the annular slot 13 to open the clamping device, so that the plug is in a soft connection, which is convenient for connection. device can be disengaged at any time. It can be used in the field of missiles, the socket is fixedly installed on the launch frame, and the plug is installed on the projectile body. Before the projectile is launched, the connector plug is clamped and fixed by the annular card slot 13 on the tail cover 9, so as to improve the connection stability and ensure the quality of data transmission. When the projectile is fired, the projectile needs to first open the clamping device of the card slot 13, so that the plug is in a soft connection, and the connector can be pulled apart when the projectile flies out. When the projectile is launched, the plug in the soft connection has many advantages. First, it can ensure more time for data transmission and parameter correction. Second, the vibration transmitted from the connector when the projectile is fired can be reduced. Thirdly, the projectile body opens the snap-on device immediately before launching, which not only ensures that the connector is easy to disengage, but also does not reduce the connection stability of the connector before it occurs. After the projectile flies out, first pull out the connector plug to separate the grounding ring 3 of the plug from the projectile body, and then pull out the socket and plug of the connector to completely separate the connector.

Further, as shown in Figures 4-5, the grounding ring 3 is fixedly connected to the plug housing 1, and the grounding ring 3 is evenly provided with a bouncing arc-shaped contact piece, so that the outer surface of the grounding ring 3 is smooth and has good conductivity. Under normal conditions, after the projectile flies out, first pull out the connector plug to separate the grounding ring 3 of the plug from the projectile body, and then pull out the socket and plug of the connector, and the connector is completely separated. If the grounding ring 3 of the plug is not separated from the projectile after the projectile is launched, it may be that the projectile failed to launch, or the connector is abnormal.

The side sealing ring 6 is arranged between the plug housing 1 and the tail cover 9 , and the side sealing ring 6 is located between the grounding ring 3 and the tail cover 9 . It can ensure the airtightness of the plug shell and the projectile body and improve the waterproof performance.

As shown in FIG. 7 and FIG. 8 , the depths of the card cutout 14 and the card slot 13 are the same. When installing the plug, by rotating the plug, the clip 14 can be aligned with the clip device and inserted, so that the clip device can be inserted into the slot 13, and then the plug can be rotated to be clipped, which is convenient for installation.

Further, as shown in FIG. 3 and FIG. 6 , the housing 1 of the socket and plug is also provided with multiple pairs of anti-mis-insertion devices, and a reference position indication mark. It is convenient for connector installation and insertion to prevent wrong and reverse insertion.

A shielding ring 10 is provided inside the tail cover 9, and the shielding ring 10 is arranged at the tail of the tail cover 9 and outside the wire harness to reduce the electromagnetic interference received by the connector.

Further, a gasket sealing ring 11 is provided on the inner side of the connection between the plug housing 1 and the tail cover 9 . The tail cover 9 is connected with the plug housing 1 by snap connection, which is convenient for installing the shield ring 10 . The gasket sealing ring 11 can strengthen the airtightness between the tail cover 9 and the plug housing 1 and improve the waterproof performance.
