Placing the ceramic sleeve 3 into the cylindrical cavity 221 of the intermediate piece 2, and butting the two intermediate pieces 2, wherein the first boss 23 of one intermediate piece 2 is correspondingly inserted between the two second bosses 24 of the other intermediate piece 2, and the first boss 23 of the other intermediate piece 2 is correspondingly accommodated between the two second bosses 24 of the intermediate piece 2; the two side surfaces of the first boss 23 are abutted with the side surfaces of the second boss 24, so that the fixing of the intermediate piece 2 in the up-down direction is ensured; the inner side surface of the first boss 23 is abutted against the side surface of the limiting seat 21, so that the fixing of the middle pieces 2 in the left-right direction is ensured, and the relative fixing of the two middle pieces 2 is further ensured under the condition that the surfaces of the limiting seats 21 of the two middle pieces 2 are attached.

The assembly groove 11 of the integrated optical port seat 1 is matched with the spliced limiting seat 21, and the two assembled intermediate pieces 2 are fixed inside the integrated optical port seat 1.

The assembled intermediate piece 2 enters from the slot 13 at the bottom of the integrated optical port seat 1, the mutually spliced limiting seats 21 are inserted into the assembly groove 11 through the openings 111, and the assembly groove 11 and the spliced limiting seats 21 are matched and fixed.

The buckle plate 12 is matched with a slot 13 at the bottom of the integrated optical port seat 1, so as to provide support for the middle piece 2 inside the integrated optical port seat 1.

The bottom plate 41 is matched with the first groove 121 on the lower surface of the buckle plate 12, so that the fixing piece 4 is fixed on the buckle plate 12.

The clamping plate 42 is matched with the second grooves 14 on two sides of the integrated optical port seat 1, and the opening 421 is used for being matched with the fourth limiting table 15 arranged on the second grooves 14, so that the fixing piece 4 and the integrated optical port seat 1 are relatively fixed.

The pins 43 are in butt joint with the PCB, so that the integral SC connector is positioned and fixed on the PCB.

The practical application method of the integral SC connector comprises the following steps:

two different SC jumpers are inserted into the receptacles 22 at both ends of the integral SC connector, respectively.

The two sides of the SC jumper wire are scratched into the bottom surface of the clamp hook 251 along the inclined surface of the clamp hook 251, the bottom surface part of the clamp hook 251 is abutted against the peripheral limit table of the SC jumper wire, and the negative angle ensures that the periphery of the SC jumper wire is not easy to break away from the clamp hook 251 through the angle of the negative angle.

The optical signal of the SC jumper at one end is transmitted to the SC jumper at the other end through the ceramic sleeve 3.

Example 3:

in embodiment 3 of the present invention, considering that the integral SC connector may be made of metal or made of plastic, and in the use scenario of the plastic and high temperature scenario, the fixing buckle 25 is propped open when the SC jumper is inserted into the socket, after the fixing buckle 25 is propped open for many times, the fixing buckle 25 may be permanently deformed due to high temperature, the distance between the two corresponding fixing buckles 25 may be permanently increased, so that the fixing buckle 25 cannot effectively and stably fix the SC jumper, so that the upper surface of the buckle plate 12 corresponding to the position of the fixing buckle 25 and the inner upper surface of the integral optical bench 1 are provided with the abutment ramp 252, and the upper and lower surfaces of the hook 251 at the front end of the fixing buckle 25 are provided with inclined planes adapted to the abutment ramp 252, so as to ensure that when the fixing buckle 25 is propped open by the SC jumper, the upper and lower surfaces of the hook 251 are abutted against the abutment ramp 252, thereby avoiding the frequent propping open between the fixing buckles 25 to be too large, resulting in permanent deformation.

As shown in fig. 16 and 17, the abutment ramp 252 is disposed on the upper surface of the buckle 12 and the upper surface of the inside of the integral light socket 1, and correspondingly abuts the upper and lower surfaces of the hook 251, so that the hook 251 is subjected to an upward and downward abutment force, and when the fixing buckle 25 is spread by the SC jumper, the upper and lower ends of the hook 251 are subjected to an inward abutment force from the abutment ramp 252, and the middle part of the hook 251 is spread outwards and returns to the original state due to a certain elastic restoring force of the plastic product, and the positions of the upper and lower ends of the hook 251 are hardly changed, so that the whole fixing buckle 25 is prevented from being deformed to a greater extent, and further, a possibly occurring permanent deformation to a greater extent under the action of high temperature is avoided.

The inclination angle of the inclined table abutting against the upper surface of the inclined table 252 is set by a person skilled in the art on the premise of not interfering with the use of the SC jumper, all the inclination angle settings meeting the conditions should be within the protection range of the embodiment, and the inclination angle of the upper end and the lower end of the hook 251 is the same as the inclination angle of the inclined table abutting against the upper surface of the inclined table 252; the distance between the abutment ramps 252 on the same socket side is set to ensure that the abutment ramps 252 do not collide with the SC patch cord in the plugged-out state.

When the combined intermediate member 2 of the integral SC connector in embodiment 1 is fixed in the integral optical port seat 1, the combined intermediate member 2 is only fixedly supported by the abutment between the limiting seat 21 in the middle of the intermediate member 2 and the assembly groove 11, but the fixing buckle 25 is in a suspended state in the integral optical port seat 1, so that the fixation of the combined intermediate member 2 in the integral optical port seat 1 is not stable enough; the abutment ramp 252 of the present embodiment can further support and abut the fixing buckle 25, so as to further enhance the stability of fixing the combined intermediate member 2 in the integral optical bench 1.

As shown in fig. 18, compared with the solution in fig. 17, the present embodiment also provides a solution in which the height of the abutment ramp 252 is relatively smaller, and the width of the hook portion 251 of the fixing buckle 25 is relatively larger, so as to avoid the phenomenon that the abutment ramp 252 is broken due to insufficient stability in the process of abutting the hook portion 251 for a long time, and the lower abutment ramp 252 ensures the stability of the abutment ramp 252 itself, in contrast to this, the width of the hook portion 251 of the fixing buckle 25 needs to be increased to ensure that the hook portion 251 can abut against the abutment ramp 252.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
