Embodiment 1

[0014] see figure 1 and figure 2 , figure 1 It is a schematic diagram of some implementation steps of the manufacturing method of the mobile phone card cap 10 of the present embodiment, figure 2 It is a schematic diagram of the overall structure of the mobile phone card cap 10 of the present embodiment. From figure 1 and figure 2 It can be seen that a kind of manufacturing method of mobile phone card cap 10 of the present invention comprises the following steps:

[0015] Step S101: mixing ceramic powder and auxiliary materials to make a viscous elastic body.

[0016] In this step, the optional auxiliary materials include thermoplastic resin, plasticizer and friction reducer, and the mass of the thermoplastic resin accounts for 10% to 30% of the total mass of the viscous elastomer, which is optional It is 15%, 18%, 20% or 25%, etc.

[0017] Step S102: Injection-molding the viscous elastic body according to a preset shape of the cap to form a cap body.

[0018] In thi...

Embodiment 2

[0035] The mobile phone card cap 10 of this embodiment is made by the manufacturing method described in the first embodiment. Since the manufacturing method has been described in detail in Embodiment 1, the description will not be repeated here.

[0036] see figure 2 , figure 2 It is a schematic diagram of the overall structure of the mobile phone card cap 10 of the present embodiment. From figure 2 It can be seen that the mobile phone card cap 10 of the present invention is provided with a first connection hole 11, and the first connection hole 11 is used to connect the mobile phone combination card holder matched with the mobile phone card cap 10 through a fixing piece .

[0037] The present invention makes the cap body by using ceramic powder and auxiliary materials, and then removes the binder of the cap body through degreasing and sintering, and makes the linear shrinkage of the cap body less than 20%. The mobile phone card cap 10 is obtained through at least one ...

Embodiment 3

[0039] see figure 2 , image 3 and Figure 4 , figure 2 It is a schematic diagram of the overall structure of the mobile phone card cap 10 of the present embodiment, image 3 It is a schematic diagram of the overall structure that the mobile phone card cap 10 and the card holder bracket 20 of the mobile phone combination card holder of the present embodiment are connected together, Figure 4 It is a schematic diagram of the overall structure of the card tray bracket 20 of the mobile phone combination card tray of this embodiment. From figure 2 , image 3 and Figure 4 It can be seen that a mobile phone combination card holder of the present invention includes the mobile phone card cap 10 described in any one of Embodiment 1 or Embodiment 2, and a card connected to the mobile phone card cap 10 through a fixing member. Support bracket 20.

[0040] In this embodiment, the material of the card holder 20 is one or a combination of metal and plastic, of course, the materi...

Abstract

The invention discloses a combined mobile phone clamping support, a mobile phone clamping cap and a manufacturing method thereof. The manufacturing method of the mobile phone clamping cap comprises the steps of mixing ceramic powder with accessories to produce elastic projectile body; performing injection module on the elastic projectile body according to the preset clamping cap shape to form the clamping cap body; and postprocessing the clamping cap body to form the mobile phone clamping cap. The manufacturing method of the mobile phone clamping cap is simple and easy to implement and few in operation step; the mobile phone clamping cap and the combined mobile phone clamping support provided by the invention has good hand feel like jade and gentle sense of touch, has better appearance effect than metal or plastic, and has the effect of being resistant to scrub, firm and resistant to drop.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to a mobile phone combination card holder, a mobile phone card cap and a manufacturing method thereof. Background technique [0002] At present, smart phones have been widely used in society, and the smart phones have various application functions, which can meet various needs of users, and are deeply loved by users. The mobile phone card of the smart phone is relatively thin and small, and needs a special mobile phone combination card tray to be placed. The mobile phone combination card tray generally includes a card tray bracket and a mobile phone card cap connected thereto. Among them, the card tray bracket is inserted into the inside of the mobile phone, and the mobile phone card cap protrudes from the outside of the mobile phone shell. [0003] The inventors of the present application have found in the long-term research and development that in the prior art, most of the suppor...
