Problems solved by technology

However, under the trend of 3C products being light, thin, short, and small, the space for setting hot-melt copper nails in the convex post is quite limited, resulting in insufficient engagement between the copper nails and the plastic shell, resulting in a decrease in the pull-out resistance of the copper nails.
For example, the height of the post on the housing of some electronic devices is only 2.5 mm. If the general nail embedding method is used, the occlusal area is too small, so the pull-out force test in the direction opposite to the embedding direction will fail to pass. , seriously affecting the mass production of models

Embodiment Construction

[0034] figure 1 It is an exploded schematic diagram of a fixed structure according to an embodiment of the present invention. Please refer to figure 1 , the fixing structure 200 includes a fixing part 100 and a plate body 50 . The fixing member 100 includes a first step portion 110 and a second step portion 120 . The first stepped portion 110 has a plurality of interference protrusions 112 and a screw hole 114 . The interference protrusions 112 are arranged around the first stepped portion 110 , and the screw holes 114 pass through the first stepped portion 110 . The second stepped portion 120 is fixed to the first stepped portion 110 along an axis A of the screw hole 114 , and the outer dimension of the second stepped portion 120 is larger than the outer dimension of the first stepped portion 110 . In this embodiment, the first stepped portion 110 and the second stepped portion 120 may be approximately cylindrical, and the interference protrusions 112 are arranged around ...

Abstract

The invention provides a fixing structure and a fastener thereof, wherein the fastener comprises a first step portion and a second step portion. The first step portion is provided with a plurality of interference bulges and a screw hole. The interference bulges are arranged around the first step portion, and the screw hole runs through the first step portion. The second step portion is solidly connected to the first step portion along an axis of the screw hole, and an external dimension of the second step portion is greater than an external dimension of the first step portion. Based on the above, the second step portion and a second segment which runs through a groove have interference structures, so the fastener and the fixing structure can effectively achieve effect of pull-out resistance.

Description

technical field [0001] The invention relates to a fixing part, and in particular to a fixing structure providing screw locking and a fixing part thereof. Background technique [0002] At present, the plastic molding industry is widely used in electronic products such as notebook computers, mobile phones, and televisions due to the characteristics of light and strong plastic materials, easy molding, high product yield, water resistance, oil resistance, strong corrosion resistance, and low cost. middle. For the combination of multiple plastic components, in addition to directly forming matching hooks for snapping and fixing, there is also a method of embedding copper nails and then locking them with screws. [0003] As far as the embedding of the copper nails is concerned, the copper nails are usually embedded into the bosses of the plastic parts by thermal melting, so that the protrusions on the copper nails are embedded in the bosses. However, under the trend of light, thi...
