The position of the insert slot 7 is opposite to that of the conductor accommodating slot 3 , and the two do not affect each other. At the same time, for the prior art, the box cover is arranged on the V-shaped groove, and the upper surface of the box cover is provided with a boss, and then the scheme of pressing the optical fiber by the box cover and the V-shaped groove is pushed forward and backward through the push tube sleeved on the box cover and the V-shaped groove. It is also applicable to this application.

The fixing method of the conductive sheet 9 and the conductor receiving groove 3 can be to fill the gap of the conductor receiving groove 3 with glue after the conductive sheet 9 is inserted into the conductor receiving groove 3 so as to be bonded; or a side wall in the conductor receiving groove 3 is provided with a block 12, and the opposite side wall of the conductor containing groove 3 and the block 12 has a wider insertion opening (the position of the insertion opening is provided with a slope that is gradually gathered inward), or a corresponding gap is provided, and the conductive sheet 9 is pressed downward from the top of the outer side of the conductor receiving groove 3 until it is in the vertical direction The upper part is fixed between the clamp block 12 and the bottom of the conductor accommodating groove 3, so that the conductive sheet 9 is fixed in the conductor accommodating groove 3, and a card groove corresponding to the rear end 11 of the conductive sheet 9 can be provided in the accommodating cavity 2, and the conductive sheet 9 is abutted in the front and rear directions, so that the conductive sheet 9 is completely fixed in the conductor accommodating groove 3.

The front end 10 of the conductive sheet 9 is exposed from the main body of the inner housing 1. There are mainly two ways of exposure. Taking the SC fiber optic connector as an example, as shown in Figure 2 and Figure 3, the front end 10 of the conductive sheet 9 can be strip-shaped and arranged on both sides corresponding to the foolproof key 13 of the movable jacket of the SC optical fiber connector. The front end 10 of 9 is exposed from the positions on both sides of the movable jacket of the SC optical fiber connector for coupling with the claws of the adapter, so that corresponding avoidance ports can be provided at the positions of the bayonet sockets on both sides of the movable jacket or the existing bayonet sockets can be used directly.

As shown in FIG. 3 , the cover body 15 is movably disposed on the inner casing 1 and covers at least the opening of the accommodating cavity 2 in a switchable manner. Specifically, the inner housing 1 is provided with a pin shaft 16, and the cover 15 is correspondingly provided with a shaft hole, so that the cover 15 is detachably and pivotably arranged on the inner housing 1, and after the inner housing 1 is loaded with the conductive sheet 9, the cover 15 is then arranged on the inner housing 1.

The way that the cover body 15 is fixed to the inner casing 1 can be, as shown in Figure 3, a bayonet 17 is provided on the cover body 15, and a flange 18 is provided on the outer side wall of the accommodation chamber 2, so that the lid body 15 is fixed on the inner casing 1 by snapping the flange 18 into the bayonet socket 17; 19 is rotated and screwed in to fix the accommodating cavity 2 and the cover 15 relatively.

The way to configure the conductive core of the photoelectric composite cable to the conductive sheet 9 can be:

After peeling off the outer skin of the conductive core, conduct electrical connection by soldering, pasting, etc.

Or optionally, as shown in Figure 5, the rear end 11 of the conductive sheet 9 is provided with an embedding opening 20, the rear end 11 of the conductive sheet 9 is arched, and the embedding opening 20 is located at the top middle of the arched part; in this way, the conductive core is pressed into the embedding opening 20 after the outer skin of the conductive core is peeled off.

Alternatively, press the conductive core of the photoelectric composite cable into the insertion opening 20 through the cover body 15, specifically:

The cover 15 is provided with a boss 21, the boss 21 has a slope corresponding to the rear end 11 of the conductive sheet 9, and when the cover 15 is closed, the boss 21 is located at the front side or the rear side of the insertion opening 20; after the skin of the conductive core is stripped off, the conductive core is mounted on the insertion opening 20, and the conductive core protrudes from the front of the insertion opening 20. When the cover 15 is snapped closed, the boss 21 will press the conductive core and pull the conductive core. The conductive core is pressed on the arched position of the rear end of the conductive sheet 9 to realize electrical connection; or the boss is arranged at the position corresponding to the insertion opening when the cover is closed, so that when the cover 15 is snapped and closed, the boss can press the conductive core on the insertion opening 20. If the insertion opening is provided with a sharp edge, the conductive core (without peeling off the sheath) of the photoelectric composite cable can also be directly driven through the cover to enter the insertion opening and be electrically connected.

Alternatively, as shown in FIG. 6 , the rear end 11 of the conductive sheet 9 is arranged vertically, and this part is provided with an insertion opening 22 . The insertion opening 20 is also relatively vertically arranged, and the insertion opening 22 can be provided with a blade-like sharp edge, so that the conductive core of the photoelectric composite cable can be pressed into the insertion opening 22 without manually peeling off the outer skin, and the electrical connection is realized by cutting the outer skin of the conductive core through the sharp edge, or a sharp edge is set at the entry part of the insertion opening 22, and the bottom is set as an extrusion part for electrical connection. connect. The above-mentioned process can also be realized when the cover body 15 is closed. Specifically, a boss 23 is set on the cover body 15, and the boss 23 is arranged relative to the both sides of the insertion port 22, so that only the conductive core of the photoelectric composite cable with the outer skin needs to be carried on the insertion port 22 during assembly, and then the cover body 15 is fastened and closed. The conductive core can be pressed into the insertion port 22 to realize electrical connection with respect to the bosses 23 on both sides of the insertion port 22; if the insertion port 22 is a bayonet similar to a Y shape, The boss can also be arranged at a position corresponding to the insertion opening to directly press the conductive core into the insertion opening 22 .

The electrical connection is realized by the cover 15 when it is closed. Optionally, as shown in FIG. 7 , the rear end 11 of the conductive sheet 9 is provided with a piercing portion 24 . The space between the cover body 15 and the housing chamber 2 is an extrusion space, and at least a part of the piercing portion 24 is located in the extrusion space; when the lid body 15 is closed, the extrusion space gradually decreases, so that the cable body of the photoelectric composite cable placed on the piercing portion 24 is squeezed by gradually buckling the cover body 15 until the piercing portion 24 pierces into the cable body of the photoelectric composite cable, thereby realizing electrical connection. The rear end of the conductive sheet 9 is configured to have an extension part bent into the accommodation chamber 2, the extension part forms a U-shaped structure with the rear end of the conductive sheet, and the piercing part 24 is arranged on the extension part, that is, the piercing part 24 is arranged in parallel with the parts located on both sides of the accommodation chamber 2 and the piercing part 24 is located in the accommodation chamber 2 with the sharp direction upward.

The relative position of the conductive core in the photoelectric composite cable and the optical fiber core wire in the middle is fixed. When using it, only the optical fiber core wire needs to be stripped off instead of the conductive core. The conductive core is still in the main body of the photoelectric composite cable. The piercing part 24 is formed by the conductive sheet 9 , and its sharp thorns are enough to pierce the sheath of the photoelectric composite cable, while the piercing part 24 is fixed at a position corresponding to the conductive core.

The cover body 15 can be provided with a step 25 at a position corresponding to the piercing portion 24, and the piercing portion 24 and the step 25 are as close as possible to the tail to facilitate the force receiving; the photoelectric composite cable is placed in the housing cavity 2, and the photoelectric composite cable is located on the piercing portion 24 and is higher than the housing chamber 2, and the raised part is the extrusion space that needs to be squeezed. During the closing process of the cover body 15, the photoelectric composite cable is squeezed through the cover body 15, and the extrusion space is gradually reduced, so that the piercing part 24 penetrates into the photoelectric composite cable. As shown in FIG.

As shown in FIGS. 9 to 16 , the main body of the inner housing 1 is quadrilateral, having a top face, two side faces and a bottom face. The conductor accommodating groove 3 is used for accommodating and fixing a sheet-shaped conductive piece 9 , and the conductive piece 9 has a front end 10 , an extension portion 26 and a rear end 11 . The extension part 26 is mainly used for cooperating and fixing with the conductor receiving groove 3 . The rear end 11 of the conductive sheet 9 is used for electrical connection with the conductive wire of the photoelectric composite cable, which can be assembled on site or pre-connected. The conductive sheet 9 is configured as a metal conductive sheet integrally formed with the front end 10, the extension part 26 and the rear end 11, and has a reinforcing rib 27 extending from the front end 10 to the rear end 11, so as to ensure the strength of the longer conductive sheet 9 and facilitate fixing with the clamping block 12. The conductive sheet 9 is used to be fixed to the conductor receiving groove 3 , and at least the front end 10 and the rear end 11 of the conductive sheet 9 are exposed from the conductor receiving groove 3 . The front end of the conductive sheet 9 has at least a first contact portion 28 and a second contact portion 29 for electrical connection with the outside. The main bodies of the first contact portion 28 and the second contact portion 29 are arranged substantially vertically. When the conductive sheet 9 is fixed to the conductor receiving groove 3, the first contact portion 28 is arranged on the top surface, and the second contact portion 29 is arranged on the side surface. A photoelectric composite optical fiber connector is provided with two conductive sheets 9, the first contact portion 28 of the conductive sheet 9 is arranged on the same top surface or bottom surface, and the second contact portion 29 of the conductive sheet 9 is respectively arranged on two side surfaces, so it is suitable for the electrical connection method in which the conductive contact points are all located on the top surface or the bottom surface and the electrical connection method located on the two sides. When the optical fiber connector housing 1 is inserted into the housing 30, both the first contact portion 28 and the second contact portion 29 are exposed so as to be electrically connected to external devices.

The front end of each conductive sheet 9 has two conductive contact portions, so that when two conductive sheets 9 are configured, each conductive contact portion can be respectively arranged on the top surface and the side surface, so that both the top surface and the side surface can be electrically connected. In this way, the photoelectric composite connector can be electrically connected with docking equipment such as adapters on the top surface, and can also be electrically connected with docking equipment such as adapters on both sides, making the photoelectric composite connector more versatile.
