In other examples, well-known structures and processes will not be elaborated in detail to avoid unnecessary details that make the description of the utility model obscure. Therefore, the utility model is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.

[0044] Example 1

[0045] To implement an interface for optical and electrical simultaneous transmission, see Figure 1-Figure 3 As shown, this embodiment provides an optoelectronic hybrid connector, including a connecting body 1 and an optical fiber ferrule 2;

[0046] Two cable pre-buried channels 11 and a receiving cavity 12 are arranged in parallel along the length direction of the connection body 1. The receiving cavity 12 is located between the two cable pre-buried channels 11 and is located in the same plane. The optical fiber ferrule 2 is fixed in the receiving cavity 12 to form an optical transmission channel, so that the cables in the two cable pre-buried channels 11 are arranged in parallel with the optical fiber ferrule 2 in the receiving cavity 12, thereby realizing that an interface has both an optical transmission channel and an electrical transmission channel. The two ends of one side wall of the connection body 1 are respectively provided with an installation groove 13 and a crimping groove 14 with an opening direction upward. The two ends of the cable pre-buried channel 11 are respectively connected with the installation groove 13 and the crimping groove 14. After the cable is inserted into the cable pre-buried channel 11 through the installation groove 13, the crimping terminal 3 is inserted into the crimping groove 14 to fix the cable to form an electrical transmission channel. In order to enhance the compression and bending resistance of the cable during subsequent use, a crimping ring 4 is provided on the end of the connection body 1 close to the installation groove 13.

[0047] In order to enhance the stability of the optical fiber ferrule 2 in the accommodating cavity 12, according to Figure 1 , Figure 4 , Figure 5 As shown, the connector also includes a limit member 5, which is placed in the accommodating cavity 12 to limit the displacement of the optical fiber ferrule 2; in the specific implementation process, the limit member 5 includes an anti-loosening spring 51 and a limit column 52; the anti-loosening spring 51 is sleeved on the insertion section of the optical fiber ferrule 2, and its movement toward the installation slot 13 is limited by the limit column 52, so as to control the position of the optical fiber ferrule 2 in the accommodating cavity 12; in order to prevent the optical fiber ferrule 2 from slipping out of the accommodating cavity 12, the limit column 52 is arranged at one end of the accommodating cavity 12 close to the installation slot 13, and the diameter of the end of the limit column 52 abutting against the anti-loosening spring 51 is smaller than the diameter of the end close to the installation slot 13, and in actual application, the end of the limit column 52 facing away from the anti-loosening spring 51 abuts against the wire structure. The cross-sectional structure of the limit column 52 is U-shaped;

[0048] In the specific implementation process, in order to enhance the stability of the optical fiber ferrule 2 in the accommodating cavity 12, according to Figure 1-Figure 3 As shown, a clamping column 121 with a through hole 121 a is provided at one end of the accommodating cavity 12 close to the crimping groove 14 , and the handle end of the optical fiber ferrule 2 is clamped in the through hole 121 a of the clamping column 121 .

[0049] In order to facilitate the understanding of the installation status of the optical fiber during on-site operation, an observation port 15 is opened on a group of symmetrical walls in the accommodating cavity 12 near one end of the installation groove 13, and the observation port 15 corresponds to the abutting end of the anti-loosening spring 51 and the abutting end of the limit column 52.

[0050] When the connector of this embodiment needs to be used, one end of the crimping terminal 3 is connected to the cable buried in the connector, and the other end is connected to the electrical transmission channel, thereby realizing the electrical signal transmission function of the connector; at the same time, the optical fiber ferrule 2 realizes the optical signal transmission function, thereby enabling one interface to realize simultaneous optical and electrical transmission.

[0051] Example 2

[0052] Based on the content of Example 1, for example, when the connector needs to be extended and used in a specific scenario (see Figure 6-Figure 10 ), also includes an adapter 6, a group of conductors 7, and a tube lens 8; the conductors 7 and the tube lens 8 are both located in a support body 61 in the adapter 6; the interface end of the adapter 6 is adapted to the insertion end of the connection body 1, so that the optical fiber ferrule 2 is sleeved in the tube lens 8 and elastically contacts the crimping terminal 3 through the conductor 7 to achieve photoelectric simultaneous transmission. The setting of the tube lens 8 reduces the optical path insertion loss during the optical transmission process.

[0053] In the specific implementation process, see Fig. 9 , Fig.10 , Figure 12-Figure 15 There are two conductors 7, which are elastically contacted with the crimping terminals 3 to form a circuit channel;

[0054] The support body 61 is provided with a stopper 61a vertically arranged with its inner wall, and the stopper 61a is provided with a through hole 61b for the sleeve lens 8 to pass through; when the sleeve lens 8 is fixed in the inner support body 61, its two ends can be connected to the two connectors described in Example 1, that is, the two ends are connected to the handle sections of the two optical fiber ferrules 2; the upper wall of the support body 61 is provided with a guide groove 62 for the conductor 7 to be inserted, so that the conductor 7 is elastically contacted with the crimping terminal 3 after being inserted into the guide groove 62. At this time, if two connectors as in Example 1 need to be connected, the two ends of the conductor 7 are respectively connected to the crimping terminals 3 on the two connectors.

[0055] The conductor 7 is a metal electrode. Figure 6 In order to increase the bending radius of the cable and improve reliability, a sheath 9 can be put on the side of the connecting body 1 away from the adapter 6, and the mounting groove 13 and the crimping ring 4 are both sealed in the sheath 9.

[0056] As a specific solution of an embodiment, see Fig.15 The conductor 7 may be a structure with both ends bent inwardly, so that the inwardly bent end abuts against the crimping terminal 3, that is, when the connector of the first embodiment is inserted into the adapter 6, the bent end is conductively connected to the crimping terminal 3.

[0057] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and for parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the utility model.

[0059] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
