Description

Quick butt joint device for large connector

Technical Field

The invention relates to the field of connector butt joint structures, in particular to a large connector quick butt joint device.

Background

A certain underwater large-scale towing system needs to exchange information with dry-end equipment through a heavy armored towing cable in the towing process, the towing cable is electrically connected with a wet-end junction box through a large-scale watertight connector, the junction box needs to be separated from the towing cable before the wet-end equipment enters a cabin storage space, and the wet-end equipment is butted when being placed down, so that a plug cable assembly of the towing cable connector and a socket of the junction box need to be vertically butted and plugged. The plug and the socket are matched in a key groove mode of the plug and the socket to ensure that the jacks and the contact pins are plugged in a one-to-one correspondence mode, the key groove is arranged inside the connector, the plug and the socket are coaxial during butt joint, the plug is rotated to enable bosses in the plug to fall into grooves in the socket, and then threads are screwed to realize butt joint. For a small connector, the mode can easily realize butt joint, but for a large connector, a connecting cable is thick, when the connector is in butt joint, the plug and the socket are coaxial, the plug is rotated, large cable torsion needs to be overcome, and quick butt joint of the connector is difficult to realize.

Detailed Description

The invention will be described in detail below with reference to the following drawings:

example (b): as shown in attached drawings 1-3, the large connector quick butt joint device comprises a plug installation component 1 and a socket installation component 2, wherein the socket installation component 2 consists of two guide pin shafts 2-1 and a C-shaped installation base 2-2, the guide pin shafts 2-1 are vertically and fixedly arranged at one end of the installation base 2-2, the two guide pin shafts 2-1 are parallel to each other, and the other end of the installation base 2-2 is fixedly arranged on a junction box 3-5 of a connector 3 through a screw; the plug mounting assembly 1 consists of two semicircular snap rings 1-2, the top of one snap ring 1-2 extends outwards to form a boss, two positioning holes 1-3 are formed in the boss and used for inserting guide pin shafts 2-1, the two semicircular snap rings 1-2 are fixed on a plug 3-1 of the connector 3 through screws, and two handles 1-1 are welded on the peripheries of the two semicircular snap rings 1-2; the plug 3-1 is provided with a bulge and is arranged at the same side of the positioning hole 1-3, the plug 3-1 is connected with a plug cable 3-3, a socket 3-2 fixedly arranged on the junction box 3-5 is provided with a groove, the groove is arranged at the same side of the guide pin shaft 2-1 and can be embedded and matched with the bulge of the plug 3-1, and the plug is fixed by a plug connecting nut on the plug 3-1 through threads.

As a preferable technical scheme, notches which can be mutually matched are arranged at corresponding positions on the plug 3-1 and the snap ring 1-2, so that the snap ring 1-2 and the plug 3-1 are prevented from axially shifting and circumferentially rotating.

As a preferable technical scheme, the aperture of the positioning hole 1-3 is slightly larger than the diameter of the guide pin shaft 2-1.

As the preferred technical scheme, the top of the guide pin shaft 2-1 and the bottom of the positioning hole 1-3 are both provided with round corners, so that the guide effect can be achieved, and even if the plug 3-1 is not completely vertical during butt joint, the connector 3 can be smoothly butted through the guide.

The working process of the invention is as follows: during butt joint, the socket installation component 2 is fixed on the junction box 3-5 through the installation base 2-2, and the two semicircular clamping rings 1-2 are fixed on the plug 3-1 of the connector 3 through screws; when the semicircular clamping ring 1-2 and the mounting base 2-2 are mounted, attention needs to be paid to the relative position relation between the positioning hole 1-3 and the plug bulge and the relative position relation between the guide pin shaft 2-1 and the socket groove, and the plug bulge is just matched with the socket groove after the guide pin shaft 2-1 is inserted into the positioning hole 1-3. After the butting device is installed, an operator grasps the two handles 1-1 to lift the plug cable 3-3 upwards, the other operator pushes the flexible part of the cable to correct the deflection of the rigid section, the first operator rotates the connector socket 3-2 in the circumferential direction, the two positioning holes 1-3 are aligned with the two guide pin shafts 2-1, the plug 3-1 is guided downwards when the two guide pin shafts 2-1 are inserted into the two positioning holes 1-3, and the plug connecting nut is rotated after the engagement of the threads of the plug 3-1 and the socket 3-2 is confirmed until the connector 3 is butted in place. When the plug 3-1 is axially rotated, attention needs to be paid to the direction of small included angle between the positioning hole 1-3 and the guide pin shaft 2-1 to twist (the deviation is less than or equal to 180 degrees), and the problems that the plug cable 3-3 is twisted too much and the operation is difficult are avoided. If the nut only idles and can not be meshed with the socket thread, the nut is proved to be not butted in place, the handle 1-1 can be slightly shaken to apply downward pressure, the handle 1-1 is confirmed to be incapable of rotating, at the moment, the plug bulge already enters the socket groove, and the nut is rotated until the nut is butted in place.

The working principle of the invention is as follows: the design ensures that a perpendicular line D1 from the center of the socket 3-2 to the center connecting line of the two guide pin shafts 2-1 is equal to a perpendicular line D2 from the center of the plug 3-1 to the center connecting line of the two positioning holes 1-3 after the installation is finished; when the two guide pin shafts 2-1 are inserted into the two positioning holes 1-3, the coaxiality of the plug and the socket can be ensured, and the plug and the socket can be smoothly butted by just matching the plug boss and the socket groove after the positioning holes 1-3 and the guide pin shafts 2-1 are matched in place because the positioning holes 1-3 and the guide pin shafts 2-1 are respectively aligned with the plug bulge and the socket groove. The handle 1-1 increases the acting force arm, and the plug 3-1 can be twisted by using smaller torque force. The top of the guide pin shaft 2-1 and the bottom of the positioning hole 1-3 are both designed with round corners to play a role in guiding, even if the plug is not completely vertical, the connector can be smoothly butted through guidance, and the effect of completing the butting is shown in figure 3.

It should be understood that equivalent substitutions and changes to the technical solution and the inventive concept of the present invention should be made by those skilled in the art to the protection scope of the appended claims.
