Mating connection structure for shell

Abstract

A mating connection structure for a shell comprises a plurality of staggered connection teeth provided on two shell pieces, and a connection frame for connecting the two shell pieces, wherein the connection frame is fixedlysecured to the connection teeth on the two shell pieces through a fixing sheet arranged on the connection frame, the staggered connection teeth restrict the relative movement of the two shell pieces in up and down directions with top blocks arranged on the connection teeth, and the connection frame restricts the relative movement of the two shell pieces on in back and forth as well as left and right directions. Said mating connection structure has a simple structure and excellent connection strength, and does not need to occupy the usage space inside the shell, so that the circuit board design for the shell is facilitated, the volume of the shell casing is reduced, and therefore the shell has a more attracting appearance, enhancing its market competitiveness and reduces the production cost.

Description

technical field [0001] The invention relates to a casing connection structure, in particular to a casing mating connection structure. Background technique [0002] At present, the shells of portable IT equipment such as mobile phones, palmtop computers, and mobile power supplies are usually formed by joining together upper and rear shells. Existing housing mating connection methods mainly include screw connection methods and clip connection methods. [0003] In the screw connection mode, corresponding screw holes and studs are provided on the mated front and rear shells, and the screws pass through the screw holes and are screwed on the studs to connect the front and rear shells. This connection method has a simple structure, but screw holes and studs for mounting screws need to be provided inside the housing, which occupies the internal space of the housing, affects the utilization rate of the internal space of the housing, and has a low utilization rate of the internal sp...

AI Technical Summary

Problems solved by technology

Its connection strength is low, and it is easy to disengage due to falling or collision, causing the circuit board, battery and other components inside the housing to fly off, causing damage to the equipment, affecting the use of users, and causing economic losses

Moreover, no matter what kind of snap-in structure, the buckle or slot that it connects must protrude inward from the shell, occupying a certain amount of internal space in the shell, which not only brings difficulties to the design of internal parts (the design of internal components must avoid these protruding connection structure), which increases the difficulty of design, and also affects the utilization rate of the internal space of the shell, and also has the defects of the above-mentioned screw connection method

In addition, during the disassembly process, the buckle is easily deformed or broken due to improper application of force, which affects the reconnection of the shell
