Detailed Description
The accompanying drawings, which are incorporated in and constitute a part of this application, illustrate preferred embodiments of the invention and together with the description, serve to explain the principles of the invention and not to limit the scope of the invention.
The invention discloses a reliable blind-mate device of an electric connector, which comprises a plug flange plate 1, a spring mounting stud 2, a trigger plate 3, a guide pin 4, a socket 5, a guide sleeve 6, a protective cover 7 and a torsion spring 8, wherein the plug flange plate is fixedly connected with the plug flange plate; the spring mounting stud 2 comprises a spring, a stud, a threaded sleeve and a nut, the nut is mounted on the threaded sleeve, the spring is sleeved on the stud, one end of the spring is in contact with the threaded sleeve, and the other end of the spring is in contact with the plug flange plate (1); the spring mounting stud 2 is connected with the plug flange 1 by, but not limited to, the following connection modes, including welding, riveting, screwing and other connection modes. Specifically, in this embodiment, 4 spring mounting studs 2 are uniformly screwed to the plug flange 1.
Still be equipped with a plurality of uide pins 4 on the plug ring flange 1, specifically to this embodiment, 2 uide pins 4 pass through the nut fastening on the plug ring flange 1, and the one end of uide pin 4 can be for cylindrical, hemisphere, taper shape or other shapes, and the terminal surface design of direction is for certain shape be favorable to guaranteeing the axiality of uide pin and uide bushing, rectifies radial butt joint dimensional error. In particular, in the present embodiment, one end of the guide pin 4 is tapered so as to define a guide slope, and the guide pin 4 cooperates with the guide sleeve 6 to correct the radial butt dimension error.
The socket 5 comprises a socket flange with a plurality of guide sleeves 6 embedded in holes in the socket flange. Specifically, in the present embodiment, 2 guide sleeves 6 are integrally formed with the socket flange, that is, a through hole is formed in the socket flange, so that the guide sleeves 6 are formed. When the plug is inserted into the socket oppositely, the guide pin 4 on the plug and the guide sleeve 6 on the socket correct the radial dimension error through the guide inclined plane before the abutting surfaces of the plug and the socket are contacted, after the positions of the plug and the socket are guided, the contact piece of the plug and the socket starts to be inserted, namely, the pin in the plug and the hole in the socket start to be inserted, so that the damage of the electric connector caused by the radial position deviation is avoided.
When the plug is butted with the socket, the plug is attached to equipment, and the equipment often has axial butting dimension errors, which are particularly obvious on an electric connector with a large axial dimension, such as a large-scale equipment with a length of several meters. It should be noted that the axial mating dimensional error of the electrical connector can be corrected by the spring mounting studs 2 mounted on the plug flange 1 in this embodiment. Specifically, in this embodiment, the plug and the socket are both attached to the device, the compression amount of the spring mounting stud is L, and when the abutting surface of the plug and the abutting surface of the socket are on the same horizontal plane, that is, the socket and the plug of the electrical connector are just plugged, the spring of the spring mounting stud is in a compression state with a compression amount of L/2. Due to tolerances in the equipment itself, the following two situations occur: (1) when the butt joint surface of the plug is positioned below the butt joint surface of the socket, the plug pin on the plug is inserted into the jack on the socket too much, so that the electric connector is damaged, the butt joint of the plug and the socket generates a positive axial butt joint size error, and the spring on the stud is installed by compressing the spring until the compression amount is L, so that the + L/2 axial butt joint size error is corrected; (2) when the butt joint face of the plug is positioned on the butt joint face of the socket, namely when the contact pin on the plug is not in contact with the jack on the socket, the butt joint of the plug and the socket generates a negative axial butt joint size error, and the axial butt joint size error from-L/2 to 0 is corrected by adjusting the compression amount of the spring, namely controlling the compression amount of the spring to be 0 to L/2. In conclusion, on the premise of ensuring that the contact elements of the plug and the socket do not have relative displacement, the plug and the socket can continuously move in opposite directions, the spring on the spring mounting stud is compressed, the maximum compression length of the spring is L, the error size correction of +/-L/2 length can be realized in the axial direction, the axial floating of the electric connector is realized, and the reliable blind plugging of the electric connector is ensured.

Before the plug is plugged with the socket, the protective cover 7 is tightly attached and fixed on the butt joint end face of the socket through the torque generated by the torsion spring 8, the protective cover 7 is in a completely closed initial state, and the waterproof and dustproof effects are achieved on the contact face of the socket. The trigger plate 3 is installed on the plug flange plate 1, and is connected with the plug flange plate 1 through, but not limited to, the following connection modes, including welding, riveting, screwing and other connection modes, specifically to this embodiment, the trigger plate 3 is screwed on the plug flange plate 1.
In the process of inserting and closing the plug and the socket in the embodiment shown in fig. 4, after the plug is radially positioned by the guide pin and the guide sleeve, when the plug is inserted into the socket, the trigger plate 3 on the plug downwardly presses the side edge of the protective cover 7 to generate a moment opposite to that of the torsion spring, the protective cover 7 overcomes the elasticity of the torsion spring, so that the protective cover 7 is opened by rotating around the screw, when the protective cover 7 is completely and vertically opened, the plug continues to move towards the socket to complete the process of inserting and closing, and when the plug and the socket are in the state of inserting and closing, the dustproof protective cover is always in the; when the plug is separated from the socket, the trigger plate 3 on the plug moves away from the protective cover 7, and the restoring moment of the torsion spring enables the protective cover 7 to rotate around the screw to be closed until the initial state of complete closing is restored, and the contact piece of the socket is covered tightly again.
In summary, the present application provides an electrical connector reliable blind mating apparatus and an implementation method of electrical connector reliable blind mating, which solve the technical problem of how to correct the axial mating dimension error and the radial mating dimension error of an electrical connector for an application scenario without a manual operation space, especially for a device with a large axial dimension, and implement reliable blind mating of the electrical connector; meanwhile, the trigger plate and the protective cover are arranged on the plug and the socket respectively, so that the problem of shielding and protecting the butt joint surface of the electric connector under the application scene without a manual operation space is well solved, the electric connector is waterproof and dustproof, and the service life of the electric connector is prolonged.
