Description

Technical Field

[0002] With the development of 5G technology, more and more 5G access point devices (AP), network cameras and other electronic devices need to be deployed. In order to facilitate the power supply of access point devices (AP), optoelectronic composite cables have come into being. With the continuous development of the optoelectronic hybrid connector market, the existing optoelectronic hybrid connector technology is increasingly unable to meet the needs of current market applications. For example: The relevant standards for SC-type optoelectronic hybrid connectors provide Fig.10 The I-type SC-type optoelectronic hybrid connector has two independent power supply terminals on the end face with the K key; the relevant standards of the SC-type optoelectronic hybrid connector also provide the following Fig.11 and Fig.12 The type II SC optoelectronic hybrid connector has an independent power supply terminal on two opposite sides of the connector (not the end face with the K key). The difference between the type I and type II connectors is that the power supply terminals are distributed at different positions on the outside of the four sides of the connector. However, the power supply terminals of both type I and type II connectors are exposed on the outside of the product and can be easily touched by construction workers or children in a home environment. As we all know, the power supply voltage of the last 100 meters of 5G application scenario is about 48V, the current is about 2A, and the total power is about 100W. When construction workers or children touch it, it is easy to get an electric shock, causing great harm to the human body, which does not meet the requirements of safety regulations. Therefore, how to achieve anti-electric shock of optoelectronic hybrid connectors is of vital importance. Utility Model Content

DETAILED DESCRIPTION

[0034] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only some of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of this solution.

[0035] Example 1

[0036] like Figures 1 to 12 As shown, this embodiment designs an optoelectronic hybrid connector for preventing electric shock, including two parts: an optoelectronic hybrid connector body 1 and a protective cap 2 .

[0037] When in use, the optoelectronic hybrid connector body 1 is connected to the end of the optoelectronic composite cable. The rear end of the optoelectronic hybrid connector body 1 is connected to the optoelectronic composite cable, and a protective tube 1.6 can be set at the connection between the two. The front end of the protective tube 1.6 is connected to the rear end of the optoelectronic hybrid connector body 1 and is sleeved and connected to the outside of the optoelectronic composite cable, thereby limiting the bending of the optoelectronic composite cable and reducing the risk of bending damage. The front end of the optoelectronic hybrid connector body 1 is provided with an exposed light guide terminal, which is coaxially connected to the light guide core (i.e., the optical fiber part) of the optoelectronic composite cable, thereby outputting optical signals to the outside.

[0038] At least one exposed conductive terminal is arranged on the outer side wall of the optoelectronic hybrid connector body 1, and the conductive terminal is electrically connected to the corresponding conductive core of the optoelectronic composite cable; when the optoelectronic hybrid connector body 1 is plugged into the corresponding female connector, external electrical connection can be made through the conductive terminal.

[0039] The protective cap 2 is a sleeve structure that penetrates from front to back. The protective cap 2 is sleeved on the outside of the optoelectronic hybrid connector body 1. The protective cap 2 is slidably connected to the optoelectronic hybrid connector body 1, so that the protective cap 2 can slide along the front-to-back direction of the optoelectronic hybrid connector body 1 to cover or expose the conductive terminal. The length of the protective cap 2 should be greater than the length of the conductive terminal, so that the conductive terminal can be fully covered by the protective cap 2. The length of the sliding track of the protective cap 2 should be greater than the length of the conductive terminal, so that after the protective cap 2 slides backward, the conductive terminal can be more fully exposed outside the protective cap 2, and when the protective cap 2 slides forward, the conductive terminal can also be more fully covered in the protective cap 2.

[0040] The outer side wall of the optoelectronic hybrid connector body 1 is provided with a guide convex key parallel to its length direction. The guide convex key is in a strip shape and is parallel to the length direction of the optoelectronic hybrid connector body 1. A sliding key groove 2.1 is provided on the inner side wall of the protective cap 2. The sliding key groove 2.1 and the guide convex key are engaged with each other, so that when the protective cap 2 slides back and forth on the optoelectronic hybrid connector body 1, the engagement relationship between the sliding key groove 2.1 and the guide convex key can be used to achieve guidance, and at the same time, the rotation of the protective cap 2 is restricted.

[0041] The conductive terminals include a first conductive terminal 1.1, a second conductive terminal 1.2 and / or a third conductive terminal 1.3, etc. When the outer contour of the optoelectronic hybrid connector body 1 is a quadrangular prism, the first conductive terminal 1.1 is arranged on the upper side or the lower side of the optoelectronic hybrid connector body 1, and the first conductive terminals 1.1 can be two mutually parallel terminals, so as to achieve Fig.10 The electrical connection effect of the I-type SC type optoelectronic hybrid connector shown in the figure is that the two metal terminals 3 are arranged on the same side of the outer shell 4. The second conductive terminal 1.2 and the third conductive terminal 1.3 are respectively arranged on the left and right sides of the optoelectronic hybrid connector body 1, thereby achieving Figure 11 to Figure 12 The electrical connection effect of the type II SC type optoelectronic hybrid connector is shown, that is, two metal terminals 3 are arranged on opposite sides of the outer conductive shell 4.

[0042] At least one locking structure 1.4 may be provided on the outer side surface of the middle portion of the optoelectronic hybrid connector body 1, so as to reduce the probability of the protective cap 2 sliding off the optoelectronic hybrid connector body 1 by utilizing the locking structure 1.4.

[0043] The locking structure comprises a front protrusion 1.41, a rear protrusion 1.42, a locking groove 1.43 and other parts. The locking groove 1.43 is a groove structure formed between the front protrusion 1.41 and the rear protrusion 1.42. A locking protrusion 2.2 is provided on the inner side wall of the protective cap 2, and the space of the locking groove 1.43 is sufficient to accommodate the locking protrusion 2.2.

[0044] The rear side of the front protrusion 1.41 has a vertical surface or a slope with a large slope perpendicular to the optoelectronic hybrid connector body 1, so that the front protrusion 1.41 can prevent the locking protrusion 2.2 from sliding forward; the side surface of the rear side of the front protrusion 1.41 is the groove wall on the front side of the locking groove 1.43, which can be against the locking protrusion 2.2 and prevent the locking protrusion 2.2 from sliding forward out of the locking groove 1.43, thereby preventing the protective cap 2 from falling off from the front end of the optoelectronic hybrid connector body 1. In addition, the protrusion height of the front protrusion 1.41 is generally greater than the protrusion height of the rear protrusion 1.42; the front protrusion 1.41 can adopt a structure with a trapezoidal or triangular cross-section; the waist on the front side of the front protrusion 1.41 is inclined and can cooperate with the inclined surface of the locking protrusion 2.2, so as to provide a guiding effect when the protective cap 2 is assembled from front to back on the optoelectronic hybrid connector body 1, so as to facilitate the assembly of the protective cap 2 to the outside of the optoelectronic hybrid connector body 1; the waist on the rear side of the front protrusion 1.41 constitutes the groove wall on the front side of the locking groove 1.43.

[0045] The rear protrusion 1.42 is located at the rear side of the front protrusion 1.41, and the protrusion height of the rear protrusion 1.42 is smaller than that of the front protrusion 1.41. The inclined surface on the front side and the inclined surface on the rear side of the rear protrusion 1.42 can cooperate with the inclined surface of the locking protrusion 2.2. The inclined surface on the front side of the rear protrusion 1.42 (i.e., the groove wall on the rear side of the locking groove 1.43) can provide resistance to the sliding of the protective cap 2 backward, thereby using the rear protrusion 1.42 to increase the resistance of the locking protrusion 2.2 when sliding backward. When the protective cap 2 is subjected to external force and slides backward, the locking protrusion 2.2 can slide backward out of the locking groove 1.43; and when the protective cap 2 is not subjected to external force and has a tendency to slide backward, it can prevent the locking protrusion 2.2 from sliding backward out of the locking groove 1.43, thereby preventing the protective cap 2 from sliding forward and backward. The inclined surface on the rear side of the rear protrusion 1.42 can provide guidance when the protective cap 2 is subjected to external force and slides forward. In addition, the rear protrusion 1.42 may have a triangular or isosceles trapezoidal cross section; the locking protrusion 2.2 may have a triangular or isosceles trapezoidal cross section.

[0046] An outwardly protruding convex edge 1.5 is provided at the rear of the optoelectronic hybrid connector body 1, and the protruding height of the convex edge 1.5 is greater than the gap width between the optoelectronic hybrid connector body 1 and the protective cap 2, so that the convex edge 1.5 is used to prevent the protective cap 2 from falling off from the rear end of the optoelectronic hybrid connector body 1, and to limit the protective cap 2 when it moves to the extreme position at the rear end of the optoelectronic hybrid connector body 1.

[0047] When the locking protrusion 2.2 is placed in the locking groove 1.43, the protective cap 2 covers all the conductive terminals.

[0048] The outer contour of the optoelectronic hybrid connector body 1 is prismatic or cylindrical, which can be determined according to needs. The tube cavity of the protective cap 2 can adopt a shape that matches the optoelectronic hybrid connector body 1. The optoelectronic hybrid connector body 1 can adopt a connector that meets existing industry standards. Only the locking structure 1.4, guide convex keys and other structures are set on the outer side wall of the connector, and the protective cap 2 is installed at the same time.

[0049] The above embodiments are merely examples for the purpose of clarifying the description, and are not intended to limit the implementation methods; it is not necessary and impossible to list all implementation methods exhaustively. However, obvious changes or modifications derived therefrom are still within the scope of protection of the present technology.
