The interlocking structures of the first lock head 2000 and the first locking notch 1000 are arranged on the upper surface and the lower surface of the photoelectric hybrid connector, so that the photoelectric hybrid connector can ensure the connection stability of the male connector 1 and the female connector 2 in a vibration environment.

The above-described structures of the opto-electrical hybrid connector are described in further detail below in order to fully illustrate the complete solution provided by embodiments of the present utility model.

The above-mentioned first power transmission component 12 and the second power transmission component 22 are coupled to realize transmission of an electrical signal, and a specific manner thereof may be as shown in fig. 5, where the first power transmission component 12 includes a male end conductive terminal 13, the second power transmission component 22 includes a female end conductive terminal 220, and the male end conductive terminal 13 and the female end conductive terminal 220 abut against each other to realize electrical connection between the male end connector 1 and the female end connector 2. In one embodiment, the abutments of the female conductive terminals 220 are located inboard and outboard of each other as compared to the abutments of the male conductive terminals 13.

In order to facilitate the fixing of the female conductive terminal 220, as shown in fig. 6, the second power transmission assembly 22 further includes a columnar body 221 abutted with the second ferrule assembly 21, and a positioning member 222 fixed on the columnar body 221, where the positioning member 222 is used for embedding the female conductive terminal 220, the structure of the positioning member 222 for embedding the female conductive terminal 220 includes a rectangular groove 2220 disposed on the positioning member 222, and a section of the corresponding rectangular groove 2220 away from the fork head is fabricated with a skylight 2221, where the skylight 2221 is used for providing a welding area between the wire 3 and the second electrical terminal.

In the embodiment of the present utility model, in order to achieve stability after the installation of the male conductive terminal 13, it is preferable that, as shown in fig. 7 and 8, the male conductive terminal 13 is a strip-shaped electrical terminal, and correspondingly, four receiving cavities 101 are fabricated on the inner sides of four corners of the male connector 1 adjacent to the first shell 10, and the receiving cavities 101 are used for being empty or for being embedded into the male conductive terminal 13. As shown in fig. 9, the strip-shaped electric terminal is one of a rectangular strip, a cylindrical strip, a triangular strip and an elliptical strip.

As shown in fig. 10, in addition to the implementation of the strip-shaped male end conductive terminal 13, the present utility model provides a better alternative mode, wherein the male end conductive terminal 13 is specifically a door-shaped electric terminal, the door-shaped electric terminal is limited on the rectangular boss 140 of the middle shaft assembly 14 of the male end connector 1, and after the middle shaft assembly 14 and the first shell 10 are locked mutually, the door post 131 of the door-shaped electric terminal beyond the end surface of the middle shaft assembly 14 is embedded in the accommodating cavity 101 arranged on the corner of the first shell 10.

In order to achieve the technical characteristics of two motors of a door-shaped electric terminal, namely to achieve the same effect as the strip-shaped male-end conductive terminal 13, the utility model also provides a matched improved solution on the door-shaped electric terminal, as shown in fig. 11, wherein the door-shaped electric terminal is composed of an insulating door beam 130 and two door posts 131 which are respectively fixed on the insulating door beam 130 and are electrically isolated from each other, wherein each door post 131 comprises a welding area, and the welding areas are arranged on the insulating door beam 130 in a staggered mode.

For the supporting rod 100 disposed on the first outer shell 10, as shown in fig. 12, the supporting rod 100 may be fixedly connected with the first outer shell 10, but in a practical application scenario, after long-time use, the supporting rod 100 is frequently toggled left and right, fatigue fracture is very easy to occur at the connection position of the supporting rod 100 and the first outer shell 10, if the supporting rod 100 needs to be repaired, the whole first outer shell 10 can only be replaced, which is not beneficial to using subsequent maintenance, therefore, in a preferred scheme, the supporting rod 100 is separately disposed from the first outer shell 10, specifically including, as shown in fig. 13 and 14, a clamping plate 1002 is disposed at the bottom of the supporting rod 100, and the first outer shell 10 is provided with a corresponding clamping groove 102, and the clamping plate 1002 is coupled with the clamping groove 102. The clamping grooves 102 extend from the side surface of the first outer shell 10 to the inside of the first outer shell 10, and the clamping grooves 102 are symmetrically arranged on the upper surface and the lower surface of the first outer shell 10.

As shown in fig. 15, the number of the clamping plates 1002 is at least 1, each clamping plate 1002 is provided with a through hole 1003, the through hole 1003 is one of oval or rectangular, and the through holes 1003 penetrate through two opposite side surfaces of the clamping plate 1002. In a preferred embodiment, in consideration of stability of coupling between the clamping plate 1002 and the clamping groove 102, a maximum height of the clamping plate 1002 is greater than a height of the clamping groove 102, and a preset difference is provided between the maximum height of the clamping plate 1002 and the height of the clamping groove 102. So that interference fit can be realized between the clamping plate 1002 and the clamping groove 102, when the clamping plate 1002 is clamped in the clamping groove 102, the clamping groove 102 extrudes the clamping plate 1002 due to the through hole 1003 arranged on the clamping plate 1002, so that the clamping plate 1002 is firmly clamped in the clamping groove 102.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
