For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] As Figure 1 shown, the existing SC type photoelectric connector main body 1 includes a ceramic plug at the front end, a protective sleeve of the ceramic plug, a metal insert sheet (electrode) at the middle, a composite wire 5 at the end, and a protective shell. In a conventional state, the electrode is exposed.

[0028] The application provides an optoelectrical connector, which comprises a connector main body 1 provided with electrodes and a shell 2 sleeved on the connector main body 1, the shell 2 is provided with a through slot for exposing the conductive contacts 3 of the electrodes, and a sliding limiting portion is arranged on the side wall of the shell 2; a contact protection sleeve is sleeved on the shell 2, and the contact protection sleeve comprises a positioning portion close to the composite wire 5 and a movable portion on the other side of the positioning portion; the positioning portion is stopped by sliding to the sliding limiting portion, the movable portion shields the conductive contacts 3 in the initial state, and the movable portion moves towards the positioning portion and exposes the conductive contacts 3 in the installed state; and a reset portion is arranged, and the movable portion is reset by the reset portion and shields the conductive contacts 3 again in the disassembled state.

[0029] In specific use, the contact protection sleeve can be sleeved on the main body by sliding the front end of the connector main body 1, and is stopped when reaching the sliding limiting portion, so that the movable portion covers the conductive contacts 3; when the connector needs to be installed into an adapter, a part of the connector main body including the shell 2 is inserted into the insertion hole in the conventional state, the movable portion can move towards the positioning portion when the connector main body 1 gradually enters, and the electrodes are not exposed in the whole insertion process; when the connector is pulled out, the movable portion is reset under the action of the reset portion and covers the electrodes again, and the electrodes are not exposed in the whole pulling-out process, so that the whole connector pulling-out process is safe and stable.

[0030] The specific embodiments will be described below:

[0031] Embodiment 1:

[0032] Based on the above embodiments, as shown in Figures 2-4 and Figure 6 , the contact protection sleeve comprises a first movable sleeve 6 and a second movable sleeve 7 which are both open at two ends, the first movable sleeve 6 is provided with a first guide groove 601 in the open end close to the composite wire 5, and the first guide groove 601 is in sliding limiting cooperation with the protrusion 4; the second movable sleeve 7 is slidably installed between the first movable sleeve 6 and the shell 2 close to one end of the first movable sleeve 6, the second movable sleeve 7 is contracted towards the inside of the first movable sleeve 6 when being installed, and the first movable sleeve 6 is provided with a reset spring 8 for resetting the second movable sleeve 7.

[0033] In this embodiment, the contact protection sleeve can be sleeved on the connector body 1 from one side of the first movable sleeve 6. When the protrusions 4 on the side of the shell 2 and the first guide groove 601 in the first movable sleeve 6 are clamped, the movement is stopped. At this time, the second movable sleeve 7 can still slide on the shell 2. In the initial state, the second movable sleeve 7 covers the conductive contact 3 under the action of the reset spring 8. When inserted into the adapter socket, the second movable sleeve 7 gradually moves towards the first movable sleeve 6 and compresses the reset spring 8. At this time, the conductive contact 3 leaks out and is connected with the connecting end in the adapter socket, completing the photoelectric connection. When pulling out, the first movable sleeve 6 can be pinched and pulled out of the entire connector. During the pulling-out process of the connector, the second movable sleeve 7 gradually resets and covers the conductive contact 3 again under the action of the reset spring 8. The entire process is not easy for the operator's fingers to touch the conductive contact 3, and the entire plugging and unplugging process has high safety.

[0034] It should be noted that in the above embodiment, the reset spring 8 only needs to ensure that the second movable sleeve 7 can compress the reset spring 8 when moving towards the first movable sleeve 6. The installation position of the reset spring 8 is not limited. For example, the first movable sleeve 6 and the second movable sleeve 7 can be completely separated, and a spring is sleeved on the shell 2 between the two. The reset spring 8 does not need to be positioned at both ends. Of course, when the second movable sleeve 7 moves towards the first movable sleeve 6, there can be some overlap in the radial direction, meaning that part of the second movable sleeve 7 can be shrunk into the first movable sleeve 6, or part of the first movable sleeve 6 can be shrunk into the second movable sleeve 7. The installation position of the reset spring 8 can be adjusted as needed, and the present application will not be described again.

[0035] More specifically, as shown in Figure 6 the first movable sleeve 6 is provided with a second guide groove 602 on the side facing the second movable sleeve 7 for sliding limiting cooperation with the second movable sleeve 7. The reset spring 8 is installed at the bottom of the second guide groove 602. This embodiment provides a scenario in which part of the second movable sleeve 7 moves into the first movable sleeve 6. When the second movable sleeve 7 is compressed, the part facing the first movable sleeve 6 enters the first movable sleeve 6 and compresses the reset spring 8 inside. At the same time, when pulling out, the second movable sleeve 7 gradually resets and covers the conductive contact 3 again under the elastic resetting action of the reset spring 8.

[0036] In some optional embodiments, as shown in Figure 5 the inner wall of the second movable sleeve 7 is provided with a third guide groove 701 along the sliding direction thereof; and a guide strip 9 is arranged on the side wall of the shell 2 for sliding limiting cooperation with the third guide groove 701. In this embodiment, a sliding limiting mechanism is arranged between the second movable sleeve 7 and the shell 2. When the second movable sleeve 7 slides, the third guide groove 701 and the guide strip 9 on the shell 2 are limited in the sliding direction, further improving the stability of the second movable sleeve 7 when sliding.

[0037] Further, the first active sleeve 6 is provided with anti-skid lines 10 on a relative side wall, which can prevent slipping during plugging and unplugging.

[0038] Obviously, the above embodiments of the present application are merely illustrative and not intended to limit the embodiments of the present application. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, it is not necessary and impossible to enumerate all the embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
