In one embodiment, the spring is fixed with the connector flange and the structural member flange by welding, and in other embodiments, the spring can be fixedly connected with the connector flange and the structural member flange into a whole in other manners. The pretightening force and the compression amount of the spring are selected according to the displacement amount designed when two devices connected as required are used.

In one embodiment, the structural member is fixed to the surface of the device by bolts, and in other embodiments, the structural member and the device may be fixed relatively by other fixing methods.

The principle of the invention for realizing the floating connection is described in detail as follows:

as shown in fig. 1, in order to achieve electrical connection or signal connection between the device a and the device B, it is necessary to achieve this through cables and connectors. The device A is provided with a plug-in end connector 10, one end of the cable is provided with a plug-in end connector for realizing electric connection or signal connection between the device A and the device B by plug-in with the plug-in end connector on the device A, and the other end of the cable is connected with the device B. In the prior art, the opposite plug-in connector at one end of the cable has no floating connection function, so that the equipment A and the equipment B can not move in a certain range and do not have certain floating quantity.

The cable assembly with the floating connection function of the present invention is used for replacing the cable shown in fig. 1, as shown in fig. 5, the structural member in the cable assembly of the present invention is fixed on the surface of the device B opposite to the device a in a certain way (including but not limited to bolt fixing), the opposite-plug end connector 1 is arranged outside the device B and connected with the cable 2, the connector tail is provided with a connector flange, the front end of the structural member is provided with a structural member flange, the structural member flange is located between the connector flange and the structural member, the spring is fixed between the connector flange and the structural member flange, and the connector flange and the structural member flange are flexibly connected through a steel wire rope. When the equipment A and the equipment B are not inserted, the steel wire rope is slightly tensioned and fixed to enable the spring to be in a micro-compression state, as shown in fig. 3, and at the moment, the axial distance between the front end of the opposite-inserted end connector and the tail end of the structural member is DD mm. When the spring is compressed to its minimum, the axial distance between the front end of the butt connector and the end of the structural member is CC mm.

The plug-in end connector on the device A is plugged with the plug-in end connector on the cable to realize interconnection of the device A and the device B. After the inserting end and the opposite inserting end are inserted in place, the spring is compressed, and a certain compression amount (the compression amount is set according to a design value) is provided, so that opposite inserting between the equipment A and the equipment B has a certain pretightening force, and the reliability of connection is improved; at the moment, the axial distance between the front end of the opposite-plug end connector and the tail end of the structural member is RR mm, and CC mm is less than or equal to RR mm and less than DD mm.

If one of the device A and the device B translates for a certain distance, the distance between the device A and the device B is larger than the distance just when the device A and the device B are inserted in place, the spring is stretched, the compression amount is reduced, but the spring still has a certain pretightening force, and good connection between the device A and the device B can still be kept. If the displacement between the device A and the device B continues to be larger, and the displacement is larger than (DD-CC) mm, the opposite plug connector is separated from the plug terminal, and the connection between the device A and the device B is disconnected. Thus, the cable assembly with floating connection function of the present invention allows the maximum relative displacement between device a and device B to be (DD-CC) mm.

In another embodiment, one of the devices a and B translates a distance such that the distance between the two is smaller than the distance just in place, and the spring compression is greater and the pre-load of the spring is greater. Thus, the direction of displacement of the device a and the device B may be the mating direction of the mating end connector and the counter-mating end connector or the opposite direction to the mating direction.

Through the scheme, a certain displacement is formed between the equipment A and the equipment B, the connector cannot be disconnected, the reliability of connection is not affected, and the cable in the cable assembly cannot be stressed due to movement of one of the equipment.

The wire rope in the cable component is used for facilitating the timely disconnection between the equipment A and the equipment B, when the equipment A and the equipment B are required to be disconnected, the plug-in end connector or the opposite plug-in end connector is pulled out, the distance between the equipment A and the equipment B is increased in the pulling-out process, and when the distance is larger than (DD-CC) mm, the spring cannot stretch again due to the action of the wire rope, so that the opposite plug-in end connector and the plug-in end connector can be separated smoothly. Therefore, the wire rope can avoid the damage to the cable component and the equipment B caused by the separation of the plug-in connector from the cable when the connector is abnormally separated; at the same time, the influence of the connector separation force on the posture of the apparatus a and the like can be reduced to some extent.

Meanwhile, when the connectors are inserted in place, the springs have a certain compression amount, and when the connectors are separated, the elastic force of the springs can provide instant thrust for the equipment A, so that the equipment A has a small initial speed, and the equipment A and the equipment B can be separated to a certain extent.

Further, in one embodiment, the other end of the cable is connected to the instrument in device B via a connector (as shown in fig. 5). In other embodiments, the other end of the cable is directly connected to the instrument in device B.

On the basis of the above embodiment, the opposite plug-end connector is a plug or a socket, and correspondingly, the plug-end connector on the device a is a socket or a plug.

The above embodiment is described taking the case that the device a and the device B are on the same horizontal plane, and the plugging direction of the plugging end and the opposite plugging end of the connector is the horizontal direction. In other embodiments, the device B may be on a horizontal plane, the device a is located on the device B, and the opposite inserting directions of the plugging end connector and the opposite inserting end connector are vertical directions, at this time, after the device a and the device B are opposite inserted, the device a compresses the spring due to self gravity, and after the connectors are opposite inserted in place, the spring is in a certain compression, so that the reliability of connection can be ensured.

According to the scheme, a certain floating amount can be arranged between the equipment A and the equipment B which are connected with each other, when one of the equipment A and the equipment B is displaced within a certain range, the connector plug and the socket which are mutually inserted cannot be separated, the transmission of energy and signals in the wire harness cannot be interrupted due to certain movement (or displacement) of one equipment (or device), the connection reliability can be ensured, the cable cannot be stressed during displacement, and the cable and the equipment are prevented from being damaged.

The foregoing is merely an embodiment of the present invention, and the present invention is not limited in any way, and may have other embodiments according to the above structures and functions, which are not listed. Therefore, any simple modification, equivalent variation and modification of the above embodiments according to the technical substance of the present invention without departing from the scope of the technical solution of the present invention will still fall within the scope of the technical solution of the present invention.
