DETAILED DESCRIPTION

[0025] The technical solution of the present invention is described clearly and completely below in conjunction with the specific embodiments of the present invention. If drawings are involved, the same numbers in the drawings represent the same or similar elements. The described embodiments are only part of the embodiments of the present invention, not all. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0026] like Figure 1-8 , an easy-to-detach sealed connector with enhanced stability, comprising a socket and a plug, both of which are provided with a shell 1 and a base 2, wherein a pin 7 or a socket 4 is provided in the base 2, 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 a flange sealing ring 12 is provided on the flange fixing plate; two pairs of differential components 8 and multiple pairs of single-core components are provided on the base 2, and the differential components 8 are provided in the middle position; a grounding ring 3 and a side sealing ring 6 are provided on the outer side of the rear end of the plug shell 1. A movable tail cover 9 is connected to the rear end of the plug shell 1, and an annular card groove 13 is provided in the middle of the tail cover 9, and a symmetrical card notch 14 is provided at the rear end of the tail cover 9. The connector can be connected and separated by the socket and the plug. The sealing layer 5 is a glue-filled seal, and the sealing layer 5 can ensure the airtightness between the shell 1, the base 2 and the wire. After the socket and the plug are connected, the contact surface can be kept airtight by the flange sealing ring 12 to improve the waterproof performance of the connector. Two pairs of differential components 8 and multiple pairs of single-core components provide the connection needs of high-speed digital signals and control signals. The differential component 8 is arranged in the middle and is less affected by external interference.

[0027] The socket of the connector is fixedly installed, and the plug is fixed by the annular card slot 13 on the tail cover 9. Before the connector is disengaged, the annular card slot 13 card connection device needs to be controlled to open so that the plug is in a soft connection, which is convenient for the connector to be disengaged at any time. It can be applied to the missile field, the socket is fixedly installed on the launcher, and the plug is installed on the missile body. Before the missile body is launched, the connector plug is fixed by the annular card slot 13 on the tail cover 9 to improve the connection stability and ensure the data transmission quality. When the missile body is launched, the missile body needs to open the card slot 13 card connection device first, so that the plug is in a soft connection, and the connector can be pulled apart when the missile body flies out. When the missile body is launched, the plug is in a soft connection, which has many advantages. First, it can ensure that there is more time for data transmission and parameter correction. Secondly, it can reduce the vibration transmitted from the connector when the missile body is launched. Thirdly, the missile body opens the card connection device instantly 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 the launch. After the projectile flies out, first pull out the connector plug to separate the plug grounding ring 3 from the projectile, then pull apart the connector socket and the plug, and the connector is completely separated.

[0028] Further, if Figure 4-5The grounding ring 3 is fixedly connected to the plug housing 1, and the grounding ring 3 is evenly provided with arc-shaped contact pieces that pop up, so that the outer side of the grounding ring 3 is smooth and has good conductivity. Under normal conditions, after the projectile flies out, the connector plug is first pulled out to separate the plug grounding ring 3 from the projectile, and then the socket and plug of the connector are pulled apart to completely separate the connector. If the plug grounding ring 3 is not separated from the projectile after the projectile is launched, it may be that the projectile launch fails or the connector is abnormal.

[0029] The side sealing ring 6 is arranged between the plug housing 1 and the tail cover 9, and the side sealing ring 6 is between the grounding ring 3 and the tail cover 9. The airtightness between the plug housing and the elastic body can be ensured, and the waterproof performance can be improved.

[0030] like Figure 7 and Figure 8 The depths of the notch 14 and the slot 13 are consistent. When installing the plug, the notch 14 can be aligned with the card connection device by rotating the plug, so that the card connection device is inserted into the slot 13, and then the plug can be rotated to be connected, which is convenient for installation.

[0031] Further, if Figure 3 and Figure 6 The housing 1 of the socket and the plug is also provided with multiple pairs of anti-mis-insertion devices and reference position indicator marks, which facilitate the installation and plugging of the connector and prevent mis-insertion and reverse plugging.

[0032] A shielding ring 10 is provided inside the tail cover 9. The shielding ring 10 is provided at the tail of the tail cover 9 and outside the wire harness to reduce electromagnetic interference to the connector.

[0033] Furthermore, a gasket seal ring 11 is provided inside the connection between the plug housing 1 and the tail cover 9. The tail cover 9 and the plug housing 1 are connected by snap connection, which facilitates the installation of the shielding ring 10. The gasket seal ring 11 can enhance the airtightness of the tail cover 9 and the plug housing 1 and improve the waterproof performance.

[0034] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
