Problems solved by technology

[0003] However, the fitting unit 11 of the protective case 1 can only use the back side of the handheld device to withstand the back plate 12, so that the flange portion 14 abuts against the bottom surface of the groove 15. When the handheld device in the shell 1 moves slightly away from the back plate 12, the flange portion 14 can easily slide out of the groove 15, so that the back plate 12 is very easy to break away from the shell 13 and fall.

Embodiment Construction

[0048]The present invention will be described in detail below with reference to the drawings and embodiments.

[0049]Before the present invention is described in detail, it should be noted that in the following description, similar components are represented by the same numbers.

[0050]Refer toFigure 4 ,5, 6 is a first embodiment of the connecting unit 21 of the protective shell set 2 of the present invention. The connecting unit 21 is used to make a detachable component 22 of the protective shell set 2 and a main shell of the protective shell set 2 The bodies 23 are connected to each other.

[0051]The main housing 23 has an outer surface 231, an inner surface 232 opposite to the outer surface 231, and a side surface 233 connected between the outer surface 231 and the inner surface 232. In the first embodiment, the main casing 23 is a frame-shaped protective casing, but it is not limited to this.

[0052]The detachable component 22 has a first surface 221, a second surface 222 opposite to th...

Abstract

A connection unit of a protective casing group is used for connecting the detachable component of the protective casing group with the main casing of the protective casing group. The connection unit includes a first flange portion, a second flange portion, and a casing main groove. The first flange portion extends in a direction from the detachable component to the main casing. The second flange portion extends in a direction from one of the detachable component and the first flange portion to the main casing. The main casing groove is formed in the main casing and the second flange portion isembedded in the main casing. The connection unit can strengthen the adhesion and stability of the connection of the detachable component and the main casing, so that the detachable component is lesslikely to fall off.

Description

Technical field[0001]The invention relates to a joint structure, in particular to a joint unit for a protective shell set of a handheld device.Background technique[0002]Seefigure 1 ,23. The existing fitting unit 11 of the protective shell 1 includes a flange portion 14 extending outward from the periphery of a back plate 12, and a flange portion 14 formed on the inner surface of a housing 13 for embedding the flange portion 14置的槽15。 Set the groove 15. When the flange portion 14 is embedded in the groove 15, the back plate 12 and the housing 13 can form the protective shell 1 covering a handheld device (not shown) on three sides.[0003]However, the fitting unit 11 of the protective shell 1 can only use the back surface of the handheld device to abut the back plate 12, so that the flange portion 14 abuts against the bottom surface of the groove 15. Therefore, if it is located on the protection The hand-held device in the housing 1 is slightly moved away from the back plate 12, and the ...
