In theory, the conductive sheet of the photoelectric hybrid adapter for connection is cut in half to realize the function of the adapter with the single-side conductive sheet, therefore, the photoelectric hybrid adapter for connection is mainly described in the patent, but the person skilled in the art can know that the conductive sheet can also be applied to the single-side photoelectric hybrid adapter.

[0042] The top wall or the bottom wall 2 of the shell 1 is configured to be separable from the main body of the shell 1, the top wall or the bottom wall 2 is provided with a conductive sheet accommodating cavity 3, and the top wall or the bottom wall 2 is fixed to the main body of the shell 1 through a fixing part. Since the top wall and the bottom wall are relative, the bottom wall is described in the following description.

[0043] Embodiment 1:

[0044] As shown in FIGS. 1 to 7, since the bottom wall 2 is separated from the main body of the shell 1, an opening allowing the locking mechanism 4 to be inserted from the outside and below in the radial direction is formed on the main body of the shell 1. The middle part of the shell 1 is provided with a guide rail 5 extending in the radial direction, and the locking mechanism 4 can be clamped in. The locking mechanism 4 is a structure of the prior art, which mainly includes two clamping arms 13 for fixing the connector inserted from the insertion port. The middle part of the locking mechanism 4 is a channel for adapting the ceramic ferrule of the connector, and the device at the other end is connected to the ceramic ferrule in the channel to transmit signals.

[0045] The main body of the conductive sheet 6 is in the form of a sheet, and the main body of the conductive sheet 6 is arranged in the conductive sheet accommodating cavity 3. The conductive sheet 6 has a bending or resilient structure, and the first conductive contact 10 and the second conductive contact 11 are arranged on the bending or resilient structure. The first conductive contact 10 and the second conductive contact 11 are adapted to the conductive interface on the same side and on both sides of the photoelectric composite connector, the conductive sheet 3 has the first conductive contact 10, the first conductive contact 10 is exposed from the inner surface of the conductive sheet accommodating cavity 3, and the second conductive contact 11 is located on both sides in the shell 1 and in front of the clamping arm 13.

[0046] The second conductive contact 11 is configured as the conductive sheet 6 has an extension 12 extending along the two sides of the inner wall of the shell 1 at a position close to the insertion opening, or the extension 12 is closely arranged on the inner wall of the two sides, and the second conductive contact 11 is arranged on the extension 12 and located in front of the clamping arm 13. The rear part of the clamping arm 13 can be provided with a avoiding part 14 avoiding the inwardly extending part of the second conductive contact 11.

[0047] In this way, the conductive sheet 6 is arranged to be compatible with both cases of the optoelectrical composite connector, and of course, since the two conductive contacts are independent of each other, one can cut off one of the first conductive contact 10 or the second conductive contact 11 when in use. When in use, a pair of conductive sheets 6 is arranged in the adapter to correspond to the positive and negative electrodes of the optoelectrical composite connector.

[0048] For the non-continuing type adapter in which the conductive sheet 6 is arranged at only one end, one end of the bottom wall 2 is provided with a conductive sheet accommodating cavity 3, and the conductive sheet accommodating cavity 3 has a middle avoiding opening 7 and a side avoiding opening 8 communicating with the inner cavity of the shell 1. The middle avoiding opening 7 allows the first conductive contact 10 to be exposed, and the side avoiding opening 8 allows the extension 12 to extend out. The terminal post 9 extends downward from the side edge of the conductive sheet 6 and extends downward from the edge of the bottom wall 2.

[0049] The conductive sheet 6 is inserted into the conductive sheet accommodating cavity 3 from the front, and then the bottom wall 2 is pressed into the shell 1 as a whole. The bottom wall 2 and the shell 1 can be fixed by clamping and clamping opening cooperation or other ways such as welding. After the bottom wall 2 is fixed to the shell 1, the front end of the conductive sheet accommodating cavity 3 abuts against the frame of the insertion opening of the shell 1, so that the conductive sheet 6 is fixed. At the same time, the conductive sheet 6, for example, the extension 12 can be provided with protruding clamping points, which cooperate with the two side inner walls of the shell 1 to assist in fixing the relative position of the conductive sheet 6.

[0050] Embodiment 2:

[0051] As shown in FIG. 8, for the continuing type adapter in which the shell 1 needs to have conductive contacts at both ends, the bottom wall 2 can be provided with an avoiding opening 15 at the middle part, and the bottom wall 2 is provided with a first end conductive sheet accommodating cavity 16 and a second end conductive sheet accommodating cavity 17, and the avoiding opening 15 communicates with the first end conductive sheet accommodating cavity 16 and the second end conductive sheet accommodating cavity 17. The conductive sheet has two groups, which are the first end conductive sheet 18 and the second end conductive sheet 19. The first end conductive sheet 18 and the second end conductive sheet 19 are configured to be inserted from the first end conductive sheet accommodating cavity 16 and the second end conductive sheet accommodating cavity 17 of the bottom wall respectively, and the main bodies of the first end conductive sheet accommodating cavity 16 and the second end conductive sheet accommodating cavity 17 are close to each other at the avoiding opening 15. The two are electrically connected by welding at the joint 20 between them, so as to realize the electrical connection of the conductive sheets at both ends. Then, similar to embodiment 1, the bottom wall 2 is pressed into the shell 1.

[0052] Embodiment 3:

[0053] As shown in Fig. 9, for the two ends of the shell 1 to require the adapter with the conductive contact, the conductive sheet 6 is provided with the conductive contact at both ends. The conductive sheet accommodating cavity 21 on the bottom wall 2 is arranged to allow the conductive sheet 6 to move from both sides to the conductive sheet accommodating cavity 21 and be inserted, rather than being inserted from both ends as in Embodiments 1 and 2. In this way, a set of conductive sheets 6 with conductive contacts at both ends can be arranged.

[0054] Embodiment 4:

[0055] As shown in Figs. 10 and 11, the bottom wall is configured to have a separable outer wall assembly 22 and a limiting assembly 23. The conductive sheet 6 can be provided with conductive contacts at both ends. The inner surface of the outer wall assembly 22 is provided with groove portions 24 accommodating the main body of the conductive sheet 6 on both sides, and the middle portion of the outer wall assembly 22 is provided with a second fixing portion 25. The limiting assembly 23 is in the shape of a sheet as a whole, and the limiting assembly 23 is provided with a corresponding middle avoiding opening 7. The edge of the outer wall assembly 22 has a side avoiding portion 26, and the middle portion is provided with a clamping opening 27 cooperating with the second fixing portion 25.

[0056] The main body of the conductive sheet 6 is arranged in the groove portion 24 of the outer wall assembly 22, and the limiting assembly 23 is arranged from above to approach the outer wall assembly 22 and is fixed to the outer wall assembly 22 through the second fixing portion 25, so as to fix the conductive sheet 6 to the bottom wall. The conductive contacts of the conductive sheet 6 are exposed or protrude from the middle avoiding opening 7 and the side avoiding portion 26. In this way, the outer wall assembly 22 and the limiting assembly 23 are fixed to the main body of the outer shell 1. The difference between Embodiment 4 and Embodiments 1, 2 and 3 is that the bottom wall of Embodiment 4 is a structure that can be separated up and down as a whole, and the conductive sheet 6 is clamped between the outer wall assembly 22 and the limiting assembly 23 to be fixed, while the bottom wall 2 of Embodiments 1, 2 and 3 is an integrally formed component.

[0057] Embodiment 5:

[0058] As shown in Figs. 12 to 14, the shell includes a first shell 28 and a second shell 29, which are configured to be separated at the position where the locking mechanism 4 is arranged, i.e., separated into two parts in the middle.

[0059] The bottom wall 30 of the first and second housings 28 and 29 is provided with a conductive tab limiting portion 30, on which a middle avoiding opening and a side avoiding opening are arranged, which allow the contact of the conductive tab 6 to protrude out of or into the inner cavity of the housing. The conductive tab limiting portion 30 can be integrally formed with the first and second housings 28 and 29, and when assembled, the locking mechanism 4 is placed between the first and second housings 28 and 29, which are fixed by clamping or welding, so that the locking mechanism 4 is fixed in the housing, and the bottom walls 30 of the first and second housings 28 and 29 are integrated, so that they can be used to carry the conductive tab 6. After the conductive tab 6 is inserted, the outer wall assembly 31 separated from the main body of the housing is fixed to the housing by the fixing portion and covers the conductive tab limiting portion 30. The fixing portion can be matched with the clamping block by the bayonet, or can be fixed by welding.

[0060] The difference between example 5 and examples 1, 2, 3 and 4 is that the main body of the shell of example 5 is a split structure at both ends.

[0061] The conductive tab using the adapter in each of the above embodiments can be replaced by a single-sided conductive tab.
