Wherein, mainboard 10 also includes contact chip circle, and in the present embodiment, contact chip circle includes at least two pad 11, optional Be 3-30 pad 11, optionally 5-10 pad 11, optionally 6-8 pad 11.Certainly, contact chip circle can also It is electrode terminal or electrode slice.

Wherein, pad 11, spring probe 14 quantity respectively be at least two, and in same equipment pad 11 number Amount is no less than spring probe 14, and guarantee can at least form a kind of complete circuit loop.

Wherein, connector includes at least two spring probe 14, when bonnet 13 is covered on terminal, pad 11 and spring Formula probe 14 contacts, so that circuit board 16 is together with passing through spring probe 14 and pad 11 between functional module 17 and mainboard 10 Carry out transmitting electric energy and/or electric signal.

When transmitting electric energy and/or electric signal between bonnet circuit and mainboard 10, bonnet circuit can be used in bonnet 13 On realize different functions, such as playing music, either for being powered to terminal or for forming lighting effects etc..

By setting bonnet circuit on bonnet 13, bonnet circuit is electrically connected with by connector and mainboard 10, Jin Erchuan Transmission of electricity energy and/or electric signal so that bonnet circuit is implemented for different functions, and lid function is asked using single after solution Topic.

Optionally, each spring probe 14 includes needle shaft 18, needle tubing 19, spring 20, and the one end of needle shaft 18 passes needle tubing 19, one end is connected by spring 20 with the bottom of needle tubing 19.

Wherein, the needle shaft 18 of spring probe 14 can be prong, grab pin, one kind in the structure such as tylostyle, blade type pin.

Wherein, when needle shaft 18 contacts with pad 11, the needle shaft 18 of spring probe 14 is made bullet by the pressure of pad 11 Spring 20 is compressed, and needle shaft 18 moves with the direction away from pad 11 of going together of spring 20 1, so that needle shaft 18 and pad 11 It is brought into close contact.

Wherein, pad 11, it is made of an electrically conducting material.

Wherein, pad 11, can be one kind in the structures such as hollow ring, disc, ellipse, in the present embodiment, Pad 11 is hollow ring, and its hollow section diameter size is corresponding with the needle shaft 18 of spring probe 14.

Making when pad 11 contacts with needle shaft 18, the needle shaft 18 of pad 11 and spring probe 14, which extrudes mutually, produces pressure, The portion retracts of needle shaft 18 enter needle tubing 19, so as to the pressure certain to spring 20, and then store corresponding elastic potential energy, from And pad 11 is combined closely from each other with spring probe 14, contact resistance is reduced, to reduce by its biography Power transmission signal or electric loss of energy, and when pad 11 does not contact with spring probe 14, needle shaft 18 can spring 20 with Under the corresponding restoring force effect of elastic potential energy, nature is returned to, can be reused, adapts to the pad 11 of different size.

Spring probe 14 is set by being covered after, pad 11 is set on the mainboard 10 of terminal, can not only be caused Spring probe 14 is contacted closely with pad 11, and spring probe 14 is arranged on to the sky that can optimize mainboard 10 on bonnet 13 Between use, avoid spring probe 14 from being arranged at space-consuming caused by mainboard 10 big and hinder miscellaneous part on mainboard 10 The problems such as use, the compatibility of mainboard 10 can be optimized to adapt to the bonnet 13 with different bonnet circuits, save cost.

Certainly, the position of pad 11 and spring probe 14 is not limited with position in scheming, can also basis Design needs to be arranged in the other positions of mainboard 10 and bonnet circuit, it is only necessary to meet that its position is corresponding, can be in master Plate 10 and bonnet 13 cover rear position correspondence, realize and are electrically connected with.

Wherein, functional module 17 can be music module, it is light modules, battery module, electric ink panel module, anti-lost One kind in alarm module, motional induction module, different functional modules 17 can be used on bonnet 13 realizing different work( Can, solve the problems, such as that the function of bonnet 13 is single, so as to effectively strengthen the use function of bonnet 13.

In the present embodiment, terminal can realize different work(by replacing the bonnet 13 with different bonnet circuits Energy.

Optionally, four avris are respectively equipped with button bit 12 on mainboard 10, and four avris correspond to button bit on mainboard 10 on bonnet 13 12 position is respectively equipped with clamp 15, and button bit 12 can combine ready-made buckle structure with clamp 15, to fasten mainboard 10 and bonnet 13, make pad 11 and corresponding spring probe 14 contacts so that mainboard 10 and bonnet circuit are electrically connected with, so that mainboard The circuit that can be combined to form between 10 and bonnet circuit such as functional module 17 by pad 11 and corresponding spring probe 14 Transmit electric energy and/or electric signal.

Wherein, the effect of button bit 12 and clamp 15 is mainboard 10 and bonnet 13 is mutually interlocked, and number and shape are not To be limited shown in scheming, corresponding buckle quantity is chosen as one kind in 4 or 2,3,5,6,7,8 etc..

Wherein, when the functional module 17 on bonnet 13 is battery module, functional module 17 can be to the electricity on mainboard 10 Transmit electric energy and/or can directly be powered to mainboard 10 in pond.

Wherein, battery powered is carried when the functional module 17 on bonnet 13 can be provided with for other modules such as music module, Battery can also be not provided with and be powered by the mainboard 10 of the terminal provided with battery, also led to when the shortage electricity provided with battery The mainboard 10 provided with battery is crossed to power.

Wherein, the quantity of pad 11 shown in Fig. 1 is 9 and its arrangement mode is preferred embodiment, bullet shown in its corresponding Fig. 2 The quantity of spring formula probe 14 can be designed according to the needs of functional module 17 to use, and its quantity can be 2-25, or 5-20, Or 8-18 etc., so when the bonnet 13 with difference in functionality module 17 can be being replaced, ensure that the connected mode can be effective Transmit electric energy or electric signal.

Referring to Fig. 4, the structural representation of the embodiment of Fig. 4 the utility model mobile terminal one, utility model mobile terminal Embodiment includes the terminal rear shell that above-mentioned the utility model terminal rear shell embodiment is provided.

After the mainboard 10 and bonnet 13 of mobile terminal cover, mainboard 10 is visited by the pad 11 and spring combined closely Pin 14 connects circuit board 16, and then linkage function module 17, to realize different functions on the bonnet 13 of mobile terminal, solves The problem of function of mobile terminal bonnet 13 is single.

In the present embodiment, the functional module 17 on bonnet 13 can be interchangeable.Certainly, terminal can also by for Different bonnets 13 is changed to realize different functions.

Embodiment of the present utility model is these are only, not thereby limits the scope of the claims of the present utility model, every utilization The equivalent structure or equivalent flow conversion that the utility model specification and accompanying drawing content are made, or directly or indirectly it is used in other Related technical field, is similarly included in scope of patent protection of the present utility model.
