[0036] The present application is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0037] like Figure 1 and Figure 2As shown, for the convenience of explanation in this application, an SC type optoelectronic composite connector is taken as an example. The SC type optoelectronic composite connector has an inner shell 1 and an outer shell 2. The inner shell 1 is used to fix the optical fiber, and the front end of the inner shell 1 is provided with a communication port that cooperates with an external device. In the prior art, the inner shell 1 can be prefabricated in the factory or assembled on site using a clamp spring. Since the present application does not involve the improvement of the corresponding structure, the method of locking the optical fiber by the inner shell 1 will not be described in detail. A pair of exposed conductive contacts 4 are provided on a surface or on both sides of the inner shell 1 close to the front end. The outer shell 2 is sleeved on the inner shell 1, and the outer shell 2 can move a short distance along the inner shell 1 so as to cooperate with the card point 3 on the inner shell 1 to unlock the connector from the adapter. The outer shell 2 is provided with an avoidance groove 5 that allows the conductive contact 4 to be exposed. The above-mentioned cooperation method between the two is a prior art and will not be described in detail here.

[0038] The technical solution provided by this application is as follows Figures 1 to 9 As shown:

[0039] The outer surface of the outer shell 2 is provided with a guide rail groove 6 .

[0040] The movable member 7 is provided with a shielding portion 8 and an extension arm 9. The shielding portion 8 is arranged at the front of the extension arm 9, and the extension arm 9 cooperates with the guide rail groove 6 to enable the movable member 7 to be arranged on the outer shell 2 to move forward and backward. Figure 4 As shown, the shielding portion 8 can be moved to cover the conductive contact 4 close to the front end, and as shown Figure 5 As shown, the shielding portion 8 moves to a position close to the rear end so that the conductive contacts 4 are exposed from the outer shell 2 .

[0041] The guide rail groove 6 is configured to be provided with a protrusion at a position near the tail of the outer shell 2, and the protrusion has an inner cavity that passes through the front and back, and the extension arm 9 passes through the inner cavity, so that the movable part 7 can be arranged on the outer shell 2 to move forward and backward. The extension arm 9 is arranged close to the outer shell 2, and the guide rail groove 6 forms a ring-like structure. The extension arm 9 passes through the inner part of the ring to slide forward and backward. The tail of the extension arm 9 has a blocking platform 10, and at least a part of the blocking platform 10 protrudes from the inner cavity or the inner cavity of the guide rail groove 6. When the movable part 7 moves forward, the blocking platform 10 cooperates with the guide rail groove 6 to limit the extension arm 9 from escaping from the guide rail groove 6. During assembly, the extension arm 9 is inserted backward from the front of the guide rail groove 6, and the blocking platform 10 is passed through the inner cavity of the guide rail groove 6 through the interference fit between the blocking platform 10 and the guide rail groove 6.

[0042] The shielding part 8 is annular and sleeved on the outer shell 2, so that the conductive contacts 4 on the same surface and on both sides can be covered at the same time. The front end of the shielding part 8 is provided with a forward extending key 11 that cooperates with the key slot of the adapter. The role and function of the extending key 11 are similar to the foolproof protruding key on the connector of the prior art, and play the role of fixing the insertion direction of the connector.

[0043] The guide groove 6 and the extension arm 9 are arranged on both sides of the connector, and the movable member 7 is moved forward and backward by pushing the movable member 7, and the movable member 7 is detachably arranged on the guide groove 6, such as Figure 4 As shown, Figure 4 For the first polarity, move the movable member 7 from the guide groove 6 and rotate it 180 degrees to install it into the guide groove 6, as shown in FIG. Figure 8 As shown (the conductive contact is located at Figure 8 The bottom is not visible), this is the second polarity.

[0044] Another embodiment provided by the present application is:

[0045] A spring receiving groove 12 is provided on the inner side of the extension arm 9, and the spring receiving groove 12 extends all the way to the shielding portion 8 at the front end. The portion of the spring receiving groove 12 located at the rear end of the extension arm 9 is open, which is convenient for loading the spring. The spring receiving groove 12 is provided with a smaller diameter near the front end, i.e., the portion near the rear end, i.e., the extension arm 9, and is larger, so that it is convenient to push the spring 13 from behind the spring 13 into the narrower front end, so that the spring 13 is not easy to fall out. A receiving groove step is provided at the position near the front end of the spring receiving groove 12, and the receiving groove step is the end face of the spring receiving groove 12 located at the front end.

[0046] The outer surface of the outer shell 2 is also provided with a spring step 14, and the spring step 14 is located in the inner cavity of the guide rail groove 6. One end of the spring 13 abuts against the spring step 14, and the other end abuts against the receiving groove step. The spring 13 provides a forward movement tendency for the movable member 7. The spring receiving groove 12 is arranged on the spring step 14 and slides along the spring step 14. The spring step 14 cooperates with the guide rail groove 6 to limit the movable member 7 to slide in the front-back direction.

[0047] like Figure 6 As shown, the shielding portion 8 is configured so that when the optoelectronic composite connector is inserted into the adapter, the front end face 16 of the shielding portion 8 abuts against the adapter. In this way, when in use, the extended key 11 is aligned with the keyway of the adapter, and the optoelectronic composite connector is pushed in. At this time, the front end face 16 of the shielding portion 8 abuts against the front end face of the adapter, and the extension arm 9 cooperates with the guide groove 6 to make the main body of the movable member 7 slide backward relative to the outer shell 2, so that the outer shell 2 continues to enter the adapter, and the main body of the movable member 7 is retained outside the adapter until the optoelectronic composite connector is fixed to the adapter, and the guide groove 6 of the outer shell 2 is still located outside the adapter. And when the optoelectronic composite connector is inserted into the adapter, the shielding portion 8 is located outside the adapter and is located between the port outside the adapter and the guide groove 6, that is, the length of the outer shell 2 ensures that when the optoelectronic composite connector is inserted into the adapter, the shielding portion 8 slides backward without hindering the optoelectronic composite connector from being inserted into the adapter.

[0048] When the optoelectronic composite connector needs to be unplugged, the outer shell 2 is pulled outside the adapter or the extension arm 9 is pulled to make the outer shell 2 slide relative to the inner shell 1, thereby removing the optoelectronic composite connector from the adapter. At this time, due to the action of the spring 12, the movable member 7 is pushed forward until it covers the conductive contact 4. In the present application, the force of the spring 13 used is relatively small, as long as it can ensure that the movable member 7 can move forward.

[0049] At the same time, if Figure 7 As shown, when the optoelectronic composite connector is a field assembly type, the shielding portion 8 is provided with a corresponding avoidance position to avoid the key 15 used to lock the optical fiber. When the connector is assembled and the optical fiber is fixed, the key 15 will be removed, so it does not affect the forward and backward movement of the movable part 7.

[0050] In addition, since the above embodiment of the present application takes the SC type connector as an example, the outer shell 2 is sleeved on the inner shell 1, so in the present application, the spring step can also be provided on the inner shell 1. Fig.10 and Fig.11 As shown, the spring step 17 is arranged on the inner shell 1, and the avoidance opening 18 is arranged at the corresponding position of the outer shell 2. The avoidance opening 18 has a certain length to ensure that the spring step 17 will not hinder the outer shell 2 from retreating when the outer shell 2 moves backward to pull the connector out of the adapter.

[0051] The outer shell and inner shell in this application are relative, for example, for an SC type connector, Fig.12 and Fig.13 As shown, another embodiment of the present application is that the spring step 19 and the guide groove 20 are arranged on the inner shell 1 in the present application. At this time, the inner shell 1 can be understood as an outer shell, and the deformation should also be within the protection scope of the present application. At this time, for the SC-type connector, the shielding portion 8 is sleeved on the outer shell 21 and can move forward and backward along the outer shell 21, and a step 22 is arranged at the tail of the outer shell 21. The outer shell 21 has a similar function to the SC-type connector of the prior art, and mainly serves to complete the unlocking. A step 22 is arranged at the tail of the outer shell 21, and the step 22 is configured to have a certain distance from the guide groove 20. When the connector needs to be unplugged from the adapter, the shielding portion 8 can be pulled or the extension arm 9 extending backward from the guide groove 20 can be pulled. The shielding portion 8 contacts the front edge of the step 22 to drive the outer shell 21 to move backward to complete the unlocking.
