Description

Mobile phone shell assembly

Technical Field

The utility model relates to a cell-phone accessory, in particular to cell-phone shell subassembly.

Background

micro USB plugs are generally applied to charging plugs of smart phones, and are used all the time when smart phones appear in the market. Although a new type of plug that can prevent erroneous insertion, type-c USB, has appeared now, only a few of the latest types of mobile phones have been applied, and there are still a large number of users' smart phones that use micro USB plugs.

However, micro USB plugs have a very big disadvantage: the micro USB plug is provided with a trapezoidal section, and although the micro USB plug has a definite complementary relation with a mobile phone jack during plugging, the complementary relation is weak, namely the micro USB plug can still be plugged into the jack even if a little force is applied, misoperation is easy to occur, an inserting sheet in the intelligent mobile phone is broken, and a user can pay money and energy to maintain the intelligent mobile phone.

When a plurality of mobile phone maintenance shops are investigated, a plurality of mobile phone maintenance examples are caused by misplugging. And aiming at micro USB plug misplug products, the products do not appear on the market.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a cell-phone shell subassembly, it can prevent that the plug from misplugging and because the mobile phone damage problem that the misplugging leads to reduces the maintenance probability of cell-phone, prolongs the life of cell-phone.

In order to achieve the purpose of the utility model, the utility model provides a mobile phone shell assembly, include:

the mobile phone shell is provided with a jack;

the dustproof cover is rotatably connected with the mobile phone shell and can open or close the jack; and

the dustproof cover can be matched with the positioning groove in an inserting mode when being opened, so that the axis of the plug groove is collinear with the axis of the jack, and the plug groove is arranged to contain a plug.

The utility model discloses a mobile phone shell assembly, including mobile phone shell, shield and plug cutting ferrule, wherein, the cell-phone is placed in the mobile phone shell, and the shield rotates with the mobile phone shell to be connected to can close or open the jack on the mobile phone shell. When the mobile phone needs to be connected with a plug (such as a micro USB plug), the dustproof cover is rotated to open the jack, and the plug can pass through the jack and then be connected with a socket of the mobile phone; when the mobile phone does not need to be connected with the plug, the dustproof cover is rotated to close the jack, so that dust is prevented from entering the jack of the mobile phone.

And the plug clamping sleeve is provided with a positioning groove and a plug groove, wherein the plug groove is used for installing a fixed plug, and the positioning groove is used for being matched with the dustproof cover to position the plug clamping sleeve.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

An embodiment of the utility model provides a cell-phone shell subassembly, as shown in fig. 1, including cell-phone shell 1, shield 2 and plug cutting ferrule 3. Through the mutual cooperation of cell-phone shell 1,

shield

2, 3 triplexs of plug cutting ferrule, prevent the mistake of plug 4 (like microUSB plug) and insert.

As shown in fig. 2, the mobile phone case 1 is provided with a jack 10, and the mobile phone can be placed in the mobile phone case 1.

As shown in fig. 5 and 6, the dust cover 2 is rotatably connected to the handset case 1 so that the dust cover 2 can rotate with respect to the handset case 1 and can open or close the jack 10. When the mobile phone needs to be connected with a plug 4 (such as a micro USB plug), the dustproof cover 2 is rotated to open the jack 10, as shown in fig. 1 and 6, and the plug 4 can pass through the jack 10 and then be connected with a socket of the mobile phone; when the mobile phone is not connected with the plug 4, the dust cap 2 is rotated to close the jack 10, as shown in fig. 5, to prevent dust from entering the jack of the mobile phone.

As shown in fig. 7 and 8, the plug ferrule 3 is provided with a positioning groove 33 and a plug groove 30, the positioning groove 33 is disposed at one side of the plug groove 30, and the plug groove 30 can be used for placing the plug 4 therein. As shown in FIG. 1, the dust cap 2 can be inserted into the positioning slot 33 when opened, so that the axis of the plug slot 30 is collinear with the axis of the jack 10.

The plug groove 30 on the plug ferrule 3 is used for mounting the fixed plug 4, and the positioning groove 33 is used for cooperating with the dust cover 2 to position the plug ferrule 3. Specifically, when the mobile phone needs to be connected with the plug 4, the plug 4 can be installed and fixed in the plug slot 30, the dust cover 2 is opened, and at this time, the dust cover 2 can be inserted into the positioning slot 33, so that the plug ferrule 3 and the plug 4 are positioned. When the dust cap 2 is inserted into the positioning groove 33, it is necessary to ensure that the axis of the plug groove 30 can be collinear with the axis of the jack 10 on the mobile phone shell 1, so that the axis of the plug 4 in the plug groove 30 is collinear with the axis of the jack 10, and the plug 4 can be conveniently connected with the jack of the mobile phone after passing through the jack 10. When the mobile phone is not required to be connected with the plug 4, the plug ferrule 3 can be separated from the dust cover 2, and then the jack 10 is closed by the dust cover 2.

Due to the positioning effect of the positioning slot 33 and the dust cap 2, it is directionally desirable to place the plug 4 in the plug slot 30 in the case of a non-vertically symmetrical configuration of the plug 4. Use the cell-phone to have approximate trapezoidal USB socket, and the upside broad of socket, correspondingly, plug 4 also is approximate trapezoidal form (as shown in fig. 1 and fig. 8) for example, if it is located the right side of jack 10 on the cell-phone shell 1 after opening shield 2, then when placing plug 4 in plug groove 30, should place plug cutting ferrule 3 and make constant head tank 33 be located the right side, plug groove 30 is located the left side, and when the approximate trapezoidal plug 4 upside broad of placing in plug groove 30, just can realize the correct grafting of plug 4 and socket. Conversely, if the plug 4 is placed in the opposite direction (i.e., upside down, with the upper side of the plug 4 narrower), or the positioning groove 33 of the plug ferrule 3 is located on the left side and the plug groove 30 is located on the right side, the plug 4 cannot be correctly inserted into the socket.

The constant head tank 33 is placed in one side of plug groove 30, and after the shield 2 was pegged graft with constant head tank 33 and is cooperated, the axis of making plug groove 30 and the axis collineation of jack 10 not only helped making the socket of plug 4 correct insertion cell-phone, the condition of misplugging can not appear, moreover, the grafting process of shield 2 and constant head tank 33 can play the guide effect to the grafting of plug 4 and cell-phone socket, be convenient for plug 4 and socket to aim at, insert in the socket smoothly.
