Embodiment 1

[0029] see Figure 2 to Figure 4 , the lower end of the connecting rod 81 is formed with a horizontal insertion slot 82, the upper end of the overheating protection rod 90 is formed with an insert 92 matching the insertion slot, and a pair of limit blocks are formed at the end of the insertion bar up and down 93, the inserting strip 92 and its limiting block 93 are plugged in the insertion slot 82, and a pair of limiting bars cooperating with the limiting block 93 are formed on the outer wall of the connecting rod 81 on the upper and lower sides of the insertion slot 82 83. According to the above scheme, when the expansion block 200 pushes away the clamping block 91, the insertion strip 92 on the upper end of the overheating protection rod 90 and the limit block 93 on the insertion strip move outwards in the insertion slot 82 of the connecting rod 81, moving When reaching the opening of the insertion slot 82 , the limiting bar 83 on the connecting rod 81 blocks the limiting b...

Embodiment 2

[0031] see Figure 5 , Figure 6 , The connecting rod 81 is connected to the overheating protection rod 90 through a spring 300, and the upper and lower ends of the spring are respectively fixed on the lower end of the connecting rod 81 and the upper end of the overheating protection rod 90. According to the above scheme, when the expansion block 300 pushes away the clamping block 91, the upper end of the overheating protection rod 90 pulls the spring 300, and the spring deforms. to restore.

[0032]The present invention adds a casing 40 on the basis of the battery of the existing communication equipment, and an overheating protection device is installed in the casing. The expansion block 200 inside the 100 is heated and expands and pushes the clamping block 91 of the overheating protection rod 90 outward. When the expansion block 200 expands to a certain extent, the clamping block 91 is separated from the overheating protection seat 100, and the overheating protection rod 9...

Abstract

The invention discloses a battery overheating protection device, which comprises a rectangular shell, an upper cover and a battery core, the battery core is plugged into the shell and formed with two cylindrical electrode seats upward; the upper end of the shell is fixedly connected with a cover Shell, two sockets are formed in the middle of the upper surface of the casing, and two cooling holes are formed at both ends; a conductive column is inserted in the socket, the upper end of the conductive column is fixedly connected with the first crossbar, and the lower end of the middle part of the first crossbar A compression spring is fixedly connected; a sealing cover is plugged into the cooling hole, and the lower end of the sealing cover is formed with a connecting rod extending into the casing. The connecting rod is fixedly connected with a second cross bar, and the lower end of the connecting rod is connected with an overheating protection rod , The lower end of the overheating protection rod is formed with a laterally protruding clamping block, the clamping block is clamped on the overheating protection seat, and an expansion block is arranged in the overheating protection seat. The invention automatically disconnects the connection circuit when the battery is overheated, and at the same time opens the cooling channel to cool the battery core.

Description

Technical field: [0001] The invention relates to the technical field of communication equipment, in particular to a battery overheat protection device for communication equipment. Background technique: [0002] Communication equipment is generally divided into wired communication equipment and wireless communication equipment. Both wired communication equipment and wireless communication equipment are inseparable from power supply facilities. Mobile communication equipment is a typical wireless communication equipment, and its power supply facilities are generally removable batteries. The batteries of existing mobile communication equipment are generally lithium batteries, and lithium batteries have a disadvantage, that is, overheating will cause explosions. Therefore, it is necessary to install an overheating protection device to avoid the explosion hazard. Invention content: [0003] The purpose of the present invention is to solve the problems existing in the prior art...
