Detailed Description

The structure and principle of such a device will be apparent to those skilled in the art from the following further description of the invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 to 12, the present invention relates to a connection structure of a 16-core MPO connector and an adapter, including a first connector and an adapter. The first connector is a 16-core MPO connector, the first connector comprises a plug core, an outer shell and an inner shell, the plug core comprises a plug and a plug tail, two contact pins are arranged at the front end of the plug core, the plug tail is connected with a first spring, first steps are respectively arranged above and below the front end of the plug core, and a second step is respectively arranged at the front end inside the inner shell in the upper and lower directions. The plug is placed in the inner shell, one end of the first spring is abutted to the rear end of the plug, the plug is pushed to insert the tail, the plug moves forwards, the plug moves along the guide slope until the two first steps are abutted to the two second steps respectively, the second steps are in limit fit with the first steps, the two contact pins are exposed out of the front end of the inner shell, and meanwhile, the two clamping pieces at the upper end and the lower end of the plug tail are clamped in the grooves in the middle of the inner shell to play a role in fixing.

The adapter includes second connector and adapter shell, and the inside front end of adapter shell is located to the second connector, and the rear end of second connector is equipped with two jacks, and the upper and lower side of the inside rear end of adapter shell respectively is equipped with a fourth step, and the fourth step includes second recess and second lug. The inner shell is arranged inside the outer shell by abutting against the rear ends of the two second springs, the front end and the rear end of the inner shell are exposed out of the outer shell, the front ends of the two second springs are connected to the outer shell, third steps are respectively arranged above and below the front end outside the inner shell and comprise first grooves and first convex blocks, the adapter outer shell is sleeved on the inner shell and moves backwards, the two jacks and the two contact pins are oppositely arranged, the two contact pins are inserted into the two jacks, the adapter outer shell pushes the outer shell, the two second springs are compressed to enable the outer shell to move backwards, the first convex blocks jack up the second convex blocks, then the second convex blocks are clamped in the first grooves, the first convex blocks are clamped in the second grooves, meanwhile, the two contact pins are completely inserted into the two jacks, and the adapter outer shell wraps and fixes the inner shell.

The rear end of the outer part of the inner shell is provided with a fifth step which can increase the strength of the rear end of the inner shell of the first connector, so that the rear end of the first connector is ensured not to deform and has higher bonding strength when being subjected to lateral force; an outer chamfer is arranged on the fifth step, an inner chamfer is arranged inside the rear end of the outer shell, the outer chamfer is matched with the inner chamfer, the length of the inner shell of the first connector can be reduced, the force arm of the first connector under the same lateral force is reduced, and the backspacing stroke of the inner shell when the first connector is in butt joint is not influenced.

The front end of the inner shell is provided with a tapered hole, and the aperture of the front end of the tapered hole is larger than that of the rear end of the tapered hole. When the first connector inner shell receives the yawing force, the inner shell can fluctuate, and because the taper hole design of the inner shell, the deviation of the first connector inner shell can not be transmitted to the inserting core, thereby ensuring that the inserting core is not influenced by external force when in butt joint.

The top surface and the bottom surface of the rear end of the plug are inclined planes, so that the up-and-down floating angle of the inner shell can be increased.

Therefore, the utility model has the advantages of simple structure and convenient installation.
