[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figures 1-6 As shown, the barrel-type pre-connected junction box in this example includes a barrel body 1 and an end cover 4 that seals the barrel mouth. A connector mechanism 3 for connecting optical cables is installed on the end cover 4, such as a common pre-connector. Multiple optical cable ports can be formed on the end cover according to needs, such as a straight-through hole, two branching optical cable holes, eight pre-connectors, etc.

[0025] In this example, a buckle mechanism is added to fix the barrel body 1 and the end cover 4 with the buckle mechanism 2. Specifically, the buckle mechanism 2 includes a left half ring 21, a right half ring 22, a first arm 24, a second arm 26, and a fastener. A groove 220 extends circumferentially on the inner wall of the left half ring 21 and the right half ring 22. The left half ring 21 and the right half ring 22 are hinged at the tail end. A mounting seat 1 23 is formed on the side facing outward at the head end of the left half ring 22. The mounting seat 1 23 is hinged to the tail end of the first arm 24 for horizontal rotation. The mounting seat 25 is formed on the side facing outward at the head end of the right half ring 22. The mounting seat 25 is hinged to the tail end of the second arm 26 for horizontal rotation.

[0026] The first arm 24 and the second arm 26 are matched with each other at the ends. Specifically, a slot 241 is formed at the head end of the first arm 24, and the head end of the second arm 26 is inserted into the slot 241 to form a concave-convex fit. A socket 1 261 is formed at the head end of the first arm 24, and a socket 2 242 is formed at the slot groove wall corresponding to the openings at both ends of the socket 1 261. After the socket 1 and the socket 2 are connected, the column is used as a fastener, and the column is extended into the socket 1 and the socket 2 to lock the head ends of the first arm 24 and the second arm 26 into one.

[0027] In this example, a radially outward protruding card plate 100 is formed on the peripheral wall of the barrel mouth of the barrel body 1. During assembly, the end cover is covered on the barrel mouth, and the side of the end cover is fitted with the card plate. At this time, the left and right half rings are merged into a ring, and the side of the card plate 100 and the end cover 4 are stuck in the groove 220. After locking the first arm and the second arm with fasteners, the barrel body, the end cover, and the left and right half rings can be locked into one.

[0028] In order to simplify the correspondence process between socket one and socket two, in this example, limit columns 243 are formed on both sides of the end of mounting seat two 25 facing mounting seat one 23, and the lower part of the end of the first arm 24 toward mounting seat two 25 extends forward to form a limit rod 243, and a limit plate 244 is formed in the slot 241. During the docking process of the first arm 24 and the second arm 26, the first arm 24 and the end of mounting seat two 25 are abutted against each other for front and rear limit, and the bottom surface of the end of the second arm 26 synchronously abuts against the limit plate 244 to limit the height. The front and rear limit and the height limit cooperate to make the socket one 261 at the end of the second arm 26 correspond to the socket two 242 at the slot 241. Just insert the fastening column. When the first arm 24 abuts against the end of mounting seat two 25, the limit rod 243 extends under the limit column 251 to limit the separation of the first arm and the second arm.

[0029] In this example, a fixed bracket is added to support and fix the mechanism for docking with the cable with the fixed bracket 5. The fixed bracket 5 is in the barrel cavity and the fixed bracket 5 is fixed with the end cover 4. For example, a groove is formed at the bottom end of the fixed bracket, and an embedded column is formed at the end face of the end cover. The embedded column is embedded in the embedded groove to fix the two.

[0030] During assembly, the joint mechanism and the fixing bracket can be installed on the end cover in advance, and the mechanism for docking with the cable can be installed on the fixing bracket. The mechanism for docking with the cable can be pre-connected with the joint mechanism, and then the end cover and the barrel body can be fixed by the buckle mechanism.
