Description

Technical Field

[0001] The utility model relates to the technical field of joint box devices, in particular to a core optical cable joint box. Background Art

[0002] Fiber optic splice closures are primarily used for connecting fiber optic cable ends or branches. Common closures consist of a lid and a bottom that snap together to form the closure body. Ports are provided at each end for fiber optic cable input and output, and the base houses the fiber splice tray. To maintain the closure's tightness, elastic strips are typically added to the joints between the lid and base. However, as these strips age, their elasticity decreases and their volume shrinks, degrading the sealing performance between the closure body and base, necessitating improvements. Utility Model Content

[0003] To solve at least one of the above technical deficiencies, the present invention provides the following technical solutions:

[0004] The present application document discloses a core optical cable junction box, comprising a box body, wherein the box body comprises a box bottom, a box cover and a locking mechanism for fixing the box bottom and the box cover, wherein connecting grooves are provided at the ends of the box bottom and the box cover, and when the box bottom and the box cover are combined, the upper and lower connecting grooves form a connecting hole for connecting cables, an elastic layer is provided at the connecting groove, and an installation groove is provided at the side between the connecting grooves at both ends of the box bottom, an elastic strip is provided in the installation groove, and an end plate for limiting the separation of the elastic strip is provided at the notch of the installation groove, a through hole is provided in the middle of the end plate for the convex ridge at the end face of the box opening of the box cover to extend into, and an embedding groove is provided on the top surface of the elastic strip to engage with the convex ridge, and a top plate elastically and telescopically connected to the installation groove below the elastic strip, and the top plate abuts against the bottom surface of the elastic strip.

[0005] In this solution, the docking structure between the box cover and the box bottom is improved, and the top plate is installed elastically and telescopically. When the box body and the box bottom are combined, the convex ribs on the box cover extend from the through holes and embed into the elastic strip grooves. The top plate continues to push up to keep the elastic strip and the convex ribs tightly connected, thereby improving the sealing performance.

[0006] Furthermore, the end plate includes a left plate body and a right plate body, which are arranged side by side and are fixed to the corresponding installation groove walls by snap-fitting, so as to facilitate installation and fixation.

[0007] Furthermore, inclined surfaces are provided at the bottom surfaces of the left and right plates, and a trapezoidal groove is formed between the two inclined surfaces. The trapezoidal groove configuration helps to improve the tightness of the fit between the elastic strip and the convex ridges.

[0008] Furthermore, bosses are arranged at intervals on the bottom of the top plate, and springs are sleeved on the bosses. The bottom end of the spring abuts against the bottom wall of the installation groove, and the bosses sleeve the springs to facilitate rapid assembly of the two.

[0009] Furthermore, a number of reinforcing ribs are arranged at intervals on the sides of the box cover and the box bottom to help improve the structural strength.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The utility model improves the docking structure between the bottom and the lid. The continuous up and down movement of the top plate keeps the ridges on the lid and the elastic strips on the bottom in close contact, which helps to improve the sealing performance.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1 、 Figure 2 、 Figure 3 As shown, the core optical cable splice box in this example includes a box body, which is a common rectangular shape. The box body includes a box bottom 2, a box cover 1 and a locking mechanism 4 for fixing the box bottom 2 and the box cover 1, as shown in FIG. Figure 1 、 Figure 2As shown, the box bottom 2 and the box cover 1 are hinged at the sides to open and close up and down, and a locking mechanism 4 is installed at the opposite side. The locking mechanism can be selected according to needs. In this example, the locking mechanism is demonstrated with a card block type as an example. After the box bottom and the box cover are merged, the locking mechanism locks the two to maintain the merged state.

[0021] Connecting grooves 31 are formed at the ends of both the bottom 2 and the lid 1. When the bottom and lid are combined, the upper and lower connecting grooves form a connecting hole 3 for connecting cables. The number of connecting holes can be selected according to needs, such as four in and four out. To improve sealing, an elastic layer 14, such as a rubber layer, is laid on the connecting groove 31. A mounting groove is formed on the side between the connecting grooves at the left and right ends of the bottom, and an elastic strip 10, such as a rubber material, is installed in the mounting groove.

[0022] In this example, the end plate that restricts the elastic strip from detaching is fixed at the notch of the mounting groove, such as Figure 2 As shown, in this example, the end plate includes a left plate body 7 and a right plate body 8. The left plate body 7 and the right plate body 8 are arranged side by side at intervals. The side of the left plate body 7 is fixed by snaps or glued to the corresponding mounting groove wall, and the side of the right plate body 8 is fixed by snaps or glued to the corresponding mounting groove wall. A through hole is formed between the left and right plates for the convex ribs 6 formed on the end surface of the box lid to extend into. When the box lid and the box bottom are combined, the convex ribs extend from the through hole and abut against the elastic strip below the end plate.

[0023] The width of the elastic strip 10 is greater than the width of the middle through hole of the end plate, and the end plate is used to limit the separation of the elastic strip. In this example, a top plate 11 is placed below the elastic strip 10, and the top plate 11 is elastically and telescopically connected to the bottom wall of the mounting groove. Figure 2 As shown, a protrusion 12 is formed on the bottom surface of the top plate 11, and a spring 13 is mounted on the protrusion 12. The spring abuts against the bottom wall of the mounting groove, and the elastic strip is pushed up on the top plate by the elastic force of the spring. When in use, the convex ridges are engaged with the embedding grooves 15 on the top surface of the elastic strip, and the elastic strip is tightly fitted to the convex ridges under the upward action of the top plate.

[0024] Preferably, the left plate 7 and the right plate 8 are provided with oppositely formed inclined surfaces 9 at their bottom surfaces, and a trapezoidal groove is formed between the two inclined surfaces 9, such as Figure 2 As shown, during the process of placing the elastic strip on the top plate, the groove walls on both sides of the elastic strip embedding groove are tightly fitted with the corresponding two sides of the convex ridges due to the influence of the inclined surface.

[0025] In addition, a number of reinforcing ribs 5 may be formed at intervals on the sides of the box cover 1 and the box bottom 2 to help improve the structural strength.

[0026] The above are only preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
