[0058] The detailed description and technical contents of the present invention will be described below with reference to the accompanying drawings. However, the accompanying drawings are only for illustrative purposes and are not intended to limit the present invention.

[0059] The utility model provides a junction box for dividing a main optical fiber cable A into multiple optical fiber cables B for use, but the utility model is not limited to this, for example, it can also be used to divide a network cable (not shown) into multiple strips for use. Figures 1 to 3As shown, the junction box of the present invention includes a box body 10 and a protection cover 20 .

[0060] In the present embodiment, the box body 10 is a rectangular body and has a first side wall 101 and a second side wall 102 opposite to each other, a third side wall 103 and a fourth side wall 104 opposite to each other, and a bottom plate 105 and a top cover 106 opposite to each other. The top cover 106 in the present embodiment is pivotally mounted on the third side wall 103 and can be opened or closed relative to the box body 10 for convenient use. However, the present invention is not limited to the above-opening shape. For example, the box body 10 can also be a round cake shape, a polygonal body or other shapes.

[0061] The box body 10 has at least one inlet 11 and a plurality of outlets 12. In the present embodiment, each outlet 12 may be an optical fiber connector connected to each optical fiber cable B, but the present invention is not limited thereto. For example, when the present invention is used in conjunction with a network cable, each outlet 12 may be a network plug connector or a socket module. Each outlet 12 is located on the same side of the box body 10, and the inlet 11 is located on the other side of the box body 10. Specifically, each outlet 12 in the present embodiment is opened on the first side wall 101, and the inlet 11 is opened on the second side wall 102, the third side wall 103 or the fourth side wall 104. In the present embodiment, the number of inlets 11 is multiple and they are located on different sides of the box body 10, and each inlet 11 is located on a different side of the box body 10 from each outlet 12. Specifically, in this embodiment, there are four wire inlets 11, which are respectively opened on the second side wall 102, the third side wall 103 and the fourth side wall 104, wherein two wire inlets 11 are opened on both sides of the second side wall 102, so as to facilitate the insertion of the main optical fiber cable A into the box body 10 according to the requirements of different angles, but the utility model is not limited thereto, and the number and position of the wire inlets 11 should be adjusted accordingly according to the requirements. Among them, the main optical fiber cable A is dispersedly connected to each outlet interface 12 after being inserted into the box body 10, so as to be connected to each optical fiber cable B for individual use.

[0062] The protective cover 20 is mounted on the box body 10, and the protective cover 20 covers each outlet interface 12. In the present embodiment, the protective cover 20 is mounted on the first side wall 101 of the box body 10, but the present invention is not limited thereto. For example, the protective cover 20 can also be mounted on the second side wall 102, the third side wall 103, the fourth side wall 104, the top cover 106 or the bottom plate 105, as long as it can cover each outlet interface 12. The protective cover 20 and the box body 10 are surrounded to form a protective space 21, so that each outlet interface 12 is located in the protective space 21. In this way, the protective space 21 surrounded by the protective cover 20 and the box body 10 can protect the optical fiber cables B connected to each outlet interface 12, thereby preventing the optical fiber cables B from falling off due to being pulled or being damaged due to collision at the bend.

[0063] Further explanation, the protective cover 20 and the box body 10 are also surrounded by a pair of openings 22. Each opening 22 is located on opposite sides of the protective space 21. In the present embodiment, the protective cover 20 is generally in an inverted U shape and includes a first cover plate 201, a second cover plate 202 and a connecting plate 203, but the protective cover 20 of the present invention is not limited to this shape. The first cover plate 201 and the second cover plate 202 are connected to the box body 10, and the first cover plate 201 and the second cover plate 202 are respectively located on opposite sides of each outlet interface 12. The connecting plate 203 is connected between the first cover plate 201 and the second cover plate 202, and the connecting plate 203 is located on the side of the first cover plate 201 and the second cover plate 202 away from the box body 10. Therefore, the first cover plate 201, the second cover plate 202, the connecting plate 203 and the box body 10 together enclose a protection space 21, and the openings 22 are formed on the two opposite sides of the connecting plate 203 where the first cover plate 201 and the second cover plate 202 are not connected, so that the protection space 21 is connected to the outside through the openings 22. In this way, after connecting the outlet interfaces 12, the optical fiber cables B can be bent in the protection space 21 toward the openings 22 to be outlet, so that the protective cover 20 can protect the bending parts of the optical fiber cables B.

[0064] Furthermore, the first cover plate 201 has a plurality of buckles 201A, and the first side wall 101 of the box body 10 has a plurality of buckle holes 101A. Each buckle 201A buckles each buckle hole 101A, thereby preliminarily fixing the protective cover 20 on the box body 10. Specifically, each buckle 201A in the present embodiment extends vertically from the first cover plate 201 toward one side of the box body 10, and each buckle hole 101A is formed at the top edge of the first side wall 101, but the present invention is not limited thereto. Thus, when installing the protective cover 20, the top cover 106 of the box body 10 can be lifted up first, and the buckle 201A of the first cover plate 201 is buckled through the buckle hole 101A to the inner side of the first side wall 101, and then the top cover 106 is closed.

[0065] Further explanation, the second cover plate 202 has a plurality of connection parts 202A, and the first side wall 101 of the box body 10 has a plurality of fixing holes 101B. Each connection part 202A is respectively configured corresponding to each fixing hole 101B. In other embodiments not shown in the figures, each connection part 202A can also be an elastic hook extending from the second cover plate 202, and is buckled and fixed to each fixing hole 101B of the first side wall 101 to fix the protective cover 20 on the box body 10. This is a fixing means well known to those with ordinary knowledge in the field, so it should also fall within the protection scope of the connection part 202A of this case.

[0066] See also Figure 4 and Figure 5 As shown, the junction box of the present invention also includes a plurality of locking members 30. Each locking member 30 is respectively passed through each connection portion 202A and can be locked in each corresponding fixing hole 101B. In the present embodiment, each locking member 30 is a push-type lock, but the present invention is not limited to this. For example, each locking member 30 can also be a matching assembly of a bolt and a nut, which is a fixing means well known to those with ordinary knowledge in the field, so it should also belong to the protection scope of the locking member 30 of this case. In each locking member 30 (i.e., push-type lock) of the present embodiment, the locking member 30 (push-type lock) includes a push rod 31 and an expansion sleeve 32. The expansion sleeve 32 passes through the corresponding connection portion 202A and the corresponding fixing hole 101B, and the push rod 31 is inserted with the expansion sleeve 32 and can move between a locked position and an unlocked position. When the push rod 31 is in the locking position, the expansion sleeve 32 clamps and fixes the corresponding connection part 202A and the box body 10 to fix the protective cover 20. When the push rod 31 is in the unlocking position, the locking member 30 can be separated from the corresponding connection part 202A and the box body 10 to unlock and remove the protective cover 20.

[0067] Specifically, the two ends of the pressing rod 31 have a pressing and pulling portion 311 and a pushing portion 312 respectively. The expansion sleeve 32 includes a baffle 321 and a plurality of elastic arms 322. The baffle 321 stops on a side surface of the corresponding connecting portion 202A away from the box body 10, and the baffle 321 has a through hole 321A. Each elastic arm 322 surrounds the through hole 321A at an equal angle and is connected to the baffle 321. At the same time, each elastic arm 322 penetrates the corresponding connecting portion 202A and the corresponding fixing hole 101B and is partially exposed inside the box body 10. The pressing rod 31 penetrates the through hole 321A of the baffle 321, so that the pushing portion 312 is accommodated between the elastic arms 322, and the pressing and pulling portion 311 is exposed on the outside of the baffle 321.

[0068] By this, Figure 6As shown, when the push rod 31 is located at the unlocking position, the push portion 312 of the push rod 31 does not push against the elastic arms 322, so the outer diameter formed by the elastic arms 322 is smaller than the inner diameter of the corresponding fixing hole 101B, so that the protective cover 20 is still in a semi-fixed state with the box body 10, that is, it only relies on the buckles 201A of the first cover plate 201 to buckle with the buckle holes 101A of the first side wall 101. When the push rod 31 is pressed to the locking position, the push portion 312 of the push rod 31 pushes against the elastic arms 322 outward, so that the outer diameter formed by the elastic arms 322 is larger than the inner diameter of the corresponding fixing hole 101B, so that the elastic arms 322 are fixed to the inner side of the first side wall 101, and then the expansion sleeve 32 clamps and fixes the corresponding connecting portion 202A and the first side wall 101 with the baffle 321 and the elastic arms 322, respectively. Figure 7 It is particularly noted that when the locking member 30 in this embodiment is to be unlocked, the user only needs to pull the pressing rod 31 of each locking member 30 outward to the unlocking position, so that each elastic arm 322 can be released from the pushing portion 312 and unlocked, thereby removing the protective cover 20.

[0069] Also, see Figures 1 to 3 As shown, the protective cover 20 has a plurality of notches 23. Each notch 23 is respectively arranged corresponding to the position of each connecting portion 202A, so that the user can conveniently operate each locking member 30 through the notch 23, and then install or remove the protective cover 20 from the box body 10. Specifically, each notch 23 is formed at a corner of the first cover plate 201 and the second cover plate 202 away from the box body 10, so that the first cover plate 201 and the second cover plate 202 are both roughly trapezoidal.

[0070] In the junction box of the present invention, the main optical fiber cable A is discretely connected to each outlet interface 12 after being inserted into the box body 10, so that each optical fiber cable B can be connected for individual use, and the protective cover 20 and the protective space 21 enclosed by the box body 10 can protect the optical fiber cables B connected to each outlet interface 12, thereby preventing the optical fiber cables B from falling off due to being pulled or being damaged due to collision at the bend.

[0071] In summary, the above disclosure of the utility model is intended to enable those with ordinary knowledge in the field to clearly understand the technical content of the utility model and implement it accordingly, and is not intended to limit the scope of patent protection of the utility model. In addition, the utility model can of course have other unlisted embodiments. Without departing from the spirit and essence of the utility model, those familiar with the field should be able to evolve various corresponding changes and deformations based on the utility model, but these corresponding changes and deformations should all fall within the scope of protection of the claims of the utility model.
