At this time, the shielding member and the adapter are no longer abutted against each other. When the photoelectric connector continues to move in the direction of separation from the adapter, under the action of the pushing module, the shielding member moves toward the direction close to the contact terminals until the slider on the shielding member moves to the top of the slide groove. At this time, the shielding member again blocks the contact terminals to prevent the contact terminals from being exposed, thereby preventing the operator from touching the contact terminals during operation.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0058] This utility model provides a photoelectric connector with a protective device. Figure 1 、 Figure 2 、 Figure 3 and Figure 12, including an outer shell 2 and a shielding member 3, the outer shell 2 has an exposed contact terminal 5.1, the contact terminal 5.1 is used to be electrically connected to the adapter 6; the shielding member 3 is slidably connected to the outer shell 2 so that the shielding member 3 shields or exposes the contact terminal 5.1.

[0059] See also Figure 1 , is a schematic diagram of the three-dimensional structure of the utility model in a natural state. When the optoelectronic connector is in a natural state, that is, when the adapter 6 is not inserted, the shielding member 3 shields the contact terminal 5.1 to prevent the contact terminal 5.1 from being exposed, thereby protecting the contact terminal 5.1 and preventing the contact terminal 5.1 from being accidentally touched.

[0060] See also Figure 2 , a schematic diagram of the three-dimensional structure of the present invention after being electrically connected to the adapter, as shown in FIG. Figure 1 In the natural state shown, see Figure 12 , is a schematic diagram of the structure of the adapter of the present invention, the adapter 6 includes a shell 6.5, the shell 6.5 has a receiving cavity 6.4 for receiving the outer shell 2, and a pin terminal 6.6 is provided in the receiving cavity 6.4, and the pin terminal 6.6 is used to be electrically connected to the contact terminal 5.1.

[0061] When the photoelectric connector is needed, the photoelectric connector is inserted into the adapter 6. During the process of inserting the photoelectric connector into the adapter 6, the shielding member 3 will abut against the outer shell 6.5 of the adapter 6. At this time, the shielding member 3 will no longer move relative to the adapter 6. Since the shielding member 3 is slidingly connected to the outer shell 2, the outer shell 2 will continue to move until the contact terminal 5.1 is completely moved into the accommodating cavity 6.4, the contact terminal 5.1 is completely electrically connected to the pin terminal 6.6, the photoelectric connector is connected to the adapter 6, and the contact terminal 5.1 maintains electrical connection with the adapter 6. This process can prevent the contact terminal 5.1 from being accidentally touched.

[0062] When the photoelectric connector needs to be unlocked, the photoelectric connector needs to be pulled out of the adapter 6. During this process, the shielding member 3 continues to abut against the adapter 6 until the contact terminal 5.1 completely comes out of the accommodating cavity 6.4 inside the adapter 6. At this time, the shielding member 3 and the adapter 6 are no longer abutted, and the shielding member 3 slides relative to the outer shell 2 to block the contact terminal 5.1 again. This process can also prevent the contact terminal 5.1 from being accidentally touched.

[0063] Therefore, when the optoelectronic connector is in a natural state, in use, or unlocked, it is possible to prevent the contact terminal 5.1 from being accidentally touched.

[0064] In the present invention, a sliding assembly is provided to ensure relative sliding between the outer shell 2 and the shielding member 3 .

[0065] In the related art, the sliding assembly includes an extension arm and a guide rail groove. The extension arm is set on the shielding member 3, and the guide rail groove is set on the outer shell 2. The extension arm and the guide rail groove are slidably matched to enable the extension arm to drive the shielding member 3 to move forward and backward and be set on the outer shell 2. However, an overly long extension arm is not only easy to affect the operator's operation, but also easy to break, and is not very practical.

[0066] In the present invention, the sliding assembly includes a first sliding member and a second sliding member. Specifically, the outer shell 2 is provided with a first sliding member, and the shielding member 3 is provided with a second sliding member slidably connected to the first sliding member, so that the shielding member 3 can slide directly on the outer shell 2.

[0067] Specifically, in some embodiments, one of the first sliding member and the second sliding member is a slide groove 2.12, and the other of the first sliding member and the second sliding member is a slider 3.12; in some embodiments, one of the first sliding member and the second sliding member is a smooth surface, and the other of the first sliding member and the second sliding member is a sphere that can cooperate with the smooth surface. The first sliding member and the second sliding member of the utility model can also be other components, as long as the outer shell 2 and the shielding member 3 can slide relative to each other when the first sliding member and the second sliding member cooperate.

[0068] In the specific implementation of this utility model, please refer to Figure 5 、 Figure 8 、 Figure 9 and Figure 10 One of the first and second sliding members is a slide groove 2.12, and the other is a slider 3.12. The first sliding member is disposed on the outside of the outer shell 2, and the second sliding member is disposed on the inside of the shielding member 3. The relative sliding movement of the slide groove 2.12 and the slider 3.12 allows the shielding member 3 to be slidably connected to the outer shell 2. This also limits the position and movement distance of the shielding member 3, ensuring that the shielding member 3 always moves within a certain range relative to the outer shell 2.

[0069] Therefore, the shielding member 3 in the present invention is not limited to a ring shape, and can be a strip shape or other shapes, as long as a first sliding member is provided on the outer shell 2, a second sliding member is provided on the shielding member 3 that is slidably connected to the first sliding member, and the shielding member 3 is slidably connected to the outer shell 2 so that the shielding member 3 can cover or expose the contact terminal 5.1.

[0070] In an embodiment of the present utility model, the outer shell 2 is provided with one or more groups of slide grooves 2.12, each group of slide grooves 2.12 includes one or more slide grooves 2.12, the number of groups of slide grooves 2.12 and the number of slide grooves 2.12 in each group of slide grooves 2.12 are set as needed, and the shielding member 3 is provided with one or more groups of sliders 3.12, each group of sliders 3.12 includes one or more sliders 3.12, the number of groups of sliders 3.12 and the number of sliders 3.12 in each group of sliders 3.12 are set as needed, and each slide groove 2.12 is slidably connected to a slider 3.12.

[0071] In this utility model, please refer to Figure 3 , and also includes a pushing module 4. By setting the pushing module 4, the shielding member 3 always has a moving trend close to the contact terminal 5.1, further ensuring that the shielding member 3 shields the contact terminal 5.1.

[0072] The pushing module 4 is of type one or type two.

[0073] Form 1 is: the pushing module 4 includes an elastic member, which is arranged on the outer shell 2, and the elastic member provides the shielding member 3 with a movement tendency to approach the contact terminal 5.1.

[0074] Form two is: the pushing module 4 includes a first magnet and a second magnet, the first magnet is fixed on the shielding member 3, and the second magnet is fixed on the outer shell 2, the first magnetic pole on the first magnet is arranged opposite to the second magnetic pole of the second magnet, and the first magnetic pole and the second magnetic pole have the same polarity.

[0075] In addition, when the optoelectronic connector is in a natural state or unlocked, under the action of the pushing module 4, the shielding member 3 approaches the contact terminal 5.1 until the shielding member 3 completely blocks the contact terminal 5.1, preventing the contact terminal 5.1 from being exposed, thereby preventing the contact terminal 5.1 from being accidentally touched.

[0076] In this utility model, please refer to Figure 3 and Figure 5 , the outer shell 2 has a first receiving groove 2.13. In form 1, please refer to Figure 9 The shielding member 3 is provided with a first elastic member abutting portion 3.4, one end of the elastic member abuts against the first accommodating groove 2.13, and the other end of the elastic member abuts against the first elastic member abutting portion 3.4. Figure 1 When the optoelectronic connector is in a natural state, that is, when the adapter 6 is not inserted, the shielding member 3 shields the contact terminal 5.1. If the first receiving groove 2.13 is short, the elastic member is partially accommodated in the first receiving groove 2.13. If the first receiving groove 2.13 is long, the elastic member is completely accommodated in the first receiving groove 2.13. Please refer to Figure 2When the optoelectronic connector is inserted into the adapter 6, the shielding member 3 exposes the contact terminal 5.1, and the elastic member is compressed. At this time, the elastic member is partially accommodated in the first accommodating groove 2.13.

[0077] In the second form, the first magnet and the second magnet are arranged side by side in the first receiving groove 2.13.

[0078] In the present invention, the elastic member is a spring. The ratio of the spring's ejection length to its diameter is too large, resulting in poor spring stability. Therefore, a guide post 3.3 is required to ensure the spring's stability when under pressure and to guide the spring. Figures 8-10 One end of the guide column 3.3 is fixed to the abutting portion of the elastic member, and the other end is suspended. The extending direction of the guide column 3.3 is the same as the extending direction of the first accommodating groove 2.13, and the spring is sleeved on the guide column 3.3.

[0079] In this utility model, in order to protect the elastic member and further limit the direction of movement of the elastic member, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 13 , further comprising a cover plate 7, which is disposed outside the first receiving groove 2.13, and is integrally formed with the outer shell 2, fixedly connected or detachably connected, and the extending direction of the cover plate 7 is parallel to the extending direction of the first receiving groove 2.13. Figure 1 When the optoelectronic connector is in a natural state, that is, when the adapter 6 is not inserted, the shielding member 3 shields the contact terminal 5.1. If the cover plate 7 is short, the cover plate 7 and the first receiving groove 2.13 form a receiving space to partially receive the elastic member. If the cover plate 7 is long, the cover plate 7 and the first receiving groove 2.13 form a receiving space to completely receive the elastic member. Please refer to Figure 2 When the optoelectronic connector is inserted into the adapter 6, the shielding member 3 exposes the contact terminal 5.1 and the elastic member is compressed. At this time, the cover plate 7 and the first accommodating groove 2.13 form a receiving space to completely accommodate the elastic member.

[0080] When the cover plate 7 and the outer shell 2 are detachably connected, the cover plate 7 and the outer shell 2 are snap-fitted together, and one of the cover plate 7 and the outer shell 2 is provided with a first bayonet 2.14, and the other of the cover plate 7 and the outer shell 2 is provided with a first buckle 7.1 that is snap-fitted with the first bayonet 2.14.

[0081] In the specific embodiment of the present invention, a first buckle 7.1 is provided on the inner side of the cover plate 7, and the first buckle 7.1 is a dovetail protrusion. A first bayonet 2.14 is provided on the outer side of the outer shell 2, and the first bayonet 2.14 is a dovetail groove.

[0082] In the present invention, the cover plate 7 has a second elastic member abutting portion 7.2, one end of the elastic member abuts against the first accommodating groove 2.13 through the second elastic member abutting portion 7.2, the second elastic abutting portion abuts against the first accommodating groove 2.13, and one end of the elastic member abuts against the second elastic abutting portion.

[0083] In this utility model, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 9 and Figure 10 The shielding member 3 includes a guard plate 3.2, and the extending direction of the guard plate 3.2 is parallel to the extending direction of the first receiving groove 2.13. Figure 1 When the optoelectronic connector is in its natural state, i.e., without the adapter 6 inserted, the shielding member 3 shields the contact terminal 5.1. When the shielding plate 3.2 and the cover plate 7 are both relatively short, the shielding member 3 is slidably connected to the outer shell 2 so that the shielding plate 3.2, the cover plate 7, and the first receiving groove 2.13 are enclosed together to partially accommodate the elastic member. When either or both of the shielding plate 3.2 and the cover plate 7 are relatively long, the shielding member 3 is slidably connected to the outer shell 2 so that the shielding plate 3.2, the cover plate 7, and the first receiving groove 2.13 are enclosed together to completely accommodate the elastic member. Please refer to FIG. Figure 2 When the optoelectronic connector is inserted into the adapter 6, the shielding member 3 exposes the contact terminal 5.1 and the elastic member is compressed. At this time, the shielding member 3 is slidably connected to the outer shell 2 so that the protective plate 3.2, the cover plate 7 and the first accommodating groove 2.13 are enclosed together to completely accommodate the elastic member.

[0084] In the present invention, a protrusion is provided on the outer shell 2, and the protrusion has a through cavity. Figure 1 When the photoelectric connector is in a natural state, that is, without the adapter 6 inserted, the shielding member 3 shields the contact terminal 5.1, and the shield 3.2 is exposed from the through cavity. Figure 2 When the optoelectronic connector is inserted into the adapter 6, the guard plate 3.2 is hidden in the through cavity. By hiding the guard plate 3.2 in the through cavity, it prevents the operator's operation from being affected and avoids the guard plate 3.2 from being easily broken, thereby enhancing practicality.

[0085] During the process of inserting the photoelectric connector into the adapter 6, the protective plate 3.2 slides relative to the outer shell 2 and moves into the through cavity until the photoelectric connector and the adapter 6 are connected. The contact terminal 5.1 maintains electrical connection with the adapter 6, and the protective plate 3.2 is hidden in the through cavity. At this time, the protective plate 3.2, the cover plate 7 and the first accommodating groove 2.13 together enclose and completely accommodate the elastic member.

[0086] In this utility model, please refer to Figure 5 and Figure 6In order to facilitate the operator to use or unlock the optoelectronic connector, a contact portion for the operator's finger to touch is provided on the outer shell 2, and the outer surface of the contact portion is provided with an anti-slip structure 2.21. The anti-slip structure 2.21 is an anti-slip groove or anti-slip protrusion, etc. The operator can insert the optoelectronic connector into the adapter 6 or pull it out from the adapter 6 by pushing the contact portion with his fingers or pinching the contact portion with his fingers.

[0087] In a specific embodiment of the present invention, the protrusion serves as a contact portion, which facilitates operation by an operator.

[0088] In the present invention, the outer shell 2 is provided with an opening 2.11, and the opening 2.11 is used to expose the contact terminal 5.1.

[0089] In this utility model, please refer to Figure 1-Figure 3 , further comprising an inner housing 1, the inner housing 1 being inserted into the outer housing 2, the inner housing 1 having a mounting portion 1.1 for accommodating the contact terminal 5.1, the outer housing 2 and the inner housing 1 being integrally formed, fixedly connected or detachably connected,

[0090] The inner housing 1 is provided with mounting portions 1.1 for accommodating the contact terminals 5.1. The number of the mounting portions 1.1 is set according to the number of the contact terminals 5.1, and is usually one or two.

[0091] In the present invention, the contact terminal 5.1 is provided with a plurality of contacts, which are used to electrically connect with the adapter 6. When the optoelectronic connector is not inserted into the adapter 6, the shielding member 3 shields the contact terminal 5.1 to prevent the plurality of contacts on the contact terminal 5.1 from being exposed, thereby preventing the operator from touching the contacts.

[0092] The number of the contact terminals 5.1 of the present invention is one or more, which can be set according to the actual needs. Figure 2 , the specific embodiment of the utility model is provided with two contact terminals 5.1.

[0093] At present, the standard "YD / T_Optoelectronic hybrid active connector for communications Part 1: SC type" stipulates Type I optoelectronic connectors and Type II optoelectronic connectors. For operators, Type I optoelectronic connectors and Type II optoelectronic connectors are not universal, which brings a lot of inconvenience to the operation and maintenance construction team. In the utility model, the contact terminal 5.1 is provided with a reed contact of a Type I optoelectronic connector and / or a reed contact of a Type II optoelectronic connector, so that the optoelectronic connector provided by the utility model can be compatible with Type I and Type II optoelectronic connectors, solving the problem of universality, so that the shielding member 3 can simultaneously shield the reed contact of the Type I optoelectronic connector and / or the reed contact of the Type II optoelectronic connector.

[0099] In this utility model, please refer to Figure 8 、 Figure 9 、 Figure 10 and Figure 12 The shielding member 3 is provided with a first end face 3.11 that abuts against the adapter 6, and the adapter 6 is provided with a second end face 6.1. The shielding member 3 and the adapter 6 are abutted or released by contacting or not contacting the first end face 3.11 with the second end face 6.1.

[0100] In this utility model, please refer to Figure 8 、 Figure 9 、 Figure 10 and Figure 12 In order to limit the position of the electrical connection between the present invention and the adapter 6, the shielding member 3 includes an alignment structure 3.13 plugged into the adapter 6, and the adapter 6 is provided with a matching structure that matches the alignment structure 3.13.

[0101] Specifically, the alignment structure 3.13 is an alignment protrusion, and the matching structure is an alignment groove. By matching the alignment protrusion and the alignment groove, the first end face 3.11 on the shielding member 3 and the second end face 6.1 on the adapter 6 can be accurately abutted, thereby ensuring that the optoelectronic connector is accurately adapted to the adapter 6.

[0102] In this utility model, please refer to Figures 8-10 The shielding member 3 includes a third sleeve 3.1, the third sleeve 3.1 has a third through cavity 3.14, the third sleeve 3.1 includes a third upper wall, a third left wall, a third right wall and a third lower wall, the third upper wall, the third left wall, the third right wall and the third lower wall enclose the third through cavity 3.14, the outer shell 2 is arranged in the third through cavity 3.14, the front side of the third upper wall of the third sleeve 3.1 is provided with an alignment structure 3.13, and the adapter 6 is provided with a matching structure 6.3 adapted to the alignment structure 3.13.

The shielding member 3 and the adapter 6 are abutted or released by contacting or not contacting the first end surface 3.11 with the second end surface 6.1.

[0104] In the specific embodiment of the present utility model, please refer to Figure 8 , two guard plates 3.2 are symmetrically arranged on the third left wall and the third right wall of the third sleeve 3.1, and two sliders 3.12 are provided on the inner sides of the two guard plates 3.2. When the cover plate 7 is clamped with the outer shell 2, the guard plates 3.2 are slidably connected to the outer shell 2, and each slide groove 2.12 cooperates with a slider 3.12, so that the shielding member 3 is slidably connected to the outer shell 2, and the inner wall of the third sleeve 3.1 is provided with a first elastic member abutment portion 3.4.

[0105] Specifically, if it is necessary to insert the photoelectric connector into the adapter 6, during the process of inserting the photoelectric connector into the adapter 6, the first end surface 3.11 on the third sleeve 3.1 will abut against the second end surface 6.1 on the shell 6.5. At this time, the shielding member 3 no longer moves relative to the adapter 6, and the guard plate 3.2, the cover plate 7 and the first accommodating groove 2.13 are jointly enclosed to partially or completely accommodate the elastic member. Since the slider 3.12 on the guard plate 3.2 is slidably connected to the slide groove 2.12 on the outer shell 2, the outer shell 2 and the inner shell 1 passing through the outer shell 2 will continue to move. During the movement, the guard plate 3.2, the cover plate 7 and the first accommodating groove 2.13 are jointly enclosed to completely accommodate the elastic member. When the pushing module 4 includes an elastic member, the elastic member is compressed and the length becomes shorter. When the pushing module 4 includes a first magnet and a second magnet, the distance between the first magnet and the second magnet becomes smaller until the contact terminal 5.1 is completely moved into the accommodating cavity 6.4. At this time, the claw 6.2 clamps the step 1.2, and the contact terminal 5.1 is completely electrically connected with the pin terminal 6.6. The optoelectronic connector is connected to the adapter 6, and the contact terminal 5.1 maintains electrical connection with the adapter 6. The guard plate 3.2, the cover plate 7 and the first accommodating groove 2.13 are jointly enclosed to maintain the complete accommodation of the elastic member. During this process, the operator cannot touch the contact terminal 5.1 at all times, so it can protect the operator.

[0106] When the photoelectric connector needs to be pulled out from the adapter 6, the outer shell 2 and the inner shell 1 are not separated from the accommodating cavity 6.4 inside the adapter 6, the first end face 3.11 on the third sleeve 3.1 will continue to abut against the second end face 6.1 on the outer shell 6.5, and the guard plate 3.2, the cover plate 7 and the first accommodating groove 2.13 are jointly enclosed to keep the elastic member completely contained, and the outer shell 2 and the inner shell 1 move out of the accommodating cavity 6.4 inside the adapter 6. During the movement, the guard plate 3.2, the cover plate 7 and the first accommodating groove 2.13 are jointly enclosed to keep the elastic member completely contained. When the pushing module 4 includes an elastic member, the length of the elastic member becomes longer. When the pushing module 4 includes the first magnet and the second magnet, the distance between the first magnet and the second magnet increases until the contact terminal 5.1 is completely moved out of the accommodating cavity 6.4. At this time, the step 1.2 disengages from the claw 6.2 on the adapter 6, and the contact terminal 5.1 disengages from the pin terminal 6.6, and the shielding member 3 and the adapter 6 are no longer in contact. When the optoelectronic connector continues to move away from the adapter 6, under the action of the pushing module 4, the shielding member 3 approaches the contact terminal 5.1 until the shielding member 3 completely blocks the contact terminal 5.1, preventing the contact terminal 5.1 from being exposed and preventing the operator from touching the contact terminal 5.1 during operation.
