Abstract
The utility model discloses a kind of shell convenient for pcb board positioning, including shell ontology, the shell ontology is equipped with positioning column, the positioning column axially offers screw hole, the upper surface of the positioning column is formed with lug boss, the bolt passes through the location hole of pcb board and screw hole cooperation is attached on positioning column, and the lug boss is stuck in the positioning hole of pcb board.The bolt of the utility model passes through the location hole of pcb board and screw hole cooperation is attached on positioning column, the lug boss is stuck in the positioning hole of pcb board, so it is also able to achieve the positioning to pcb board it is not necessary that limit bone is arranged on shell ontology, reduces die cost, reduces the production cost of shell；It is realized since the positioning of pcb board only needs positioning column and bolt to cooperate, the positioning to pcb board is so also able to achieve in accommodating space again small shell, and the scope of application is more extensive.
Description
Technical field
The utility model relates to housing technologies field, in particular to a kind of shell convenient for pcb board positioning.
Background technique
In existing earphone, auricular concha to the positioning of pcb board make by pcb board surrounding design limit bony process it is existing, and
In general pcb board could be positioned by needing to be arranged a plurality of limit bone in auricular concha, so will lead to increase mold at
This, to increase the manufacturing cost of auricular concha；And part earphone leads to no enough space setting limits because its structure designs
Bone so just cannot be fixed pcb board, be easily damaged pcb board, the service life of shortening earphone during use.
Summary of the invention
The technical problems to be solved in the utility model is in view of the deficiency of the prior art, to provide a kind of convenient for PCB
The shell of plate positioning, can be existing to pcb board positioning without limiting bony process, reduces die cost, reduces the production cost of shell.
In order to solve the above technical problems, the technical solution of the utility model is:
A kind of shell convenient for pcb board positioning, including shell ontology and bolt, the shell ontology is equipped with positioning column, described
Positioning column axially offers screw hole, and the upper surface of the positioning column is formed with lug boss, and the bolt passes through the positioning of pcb board
Hole and screw hole cooperation are attached on positioning column, and the lug boss is stuck in the positioning hole of pcb board.
As a preferred embodiment, the height of the lug boss is less than the thickness of pcb board.
As a preferred embodiment, the height of the lug boss is 0.6-0.75 times of pcb board thickness.
As a preferred embodiment, the lug boss is protruding circular ring.
As a preferred embodiment, the lug boss is equipped with the guide ramp tilted down from the outside to the core.
As a preferred embodiment, the shell ontology is equipped with variable weights, and one end of the variable weights is connect with positioning column, institute
The other end for stating variable weights is connect with shell inner body wall, and the upper surface of the variable weights is a flat surface, and the plane is butted on pcb board
Lower surface.
As a preferred embodiment, the shell inner body wall is equipped with the card slot being adapted to pcb board leading protrusions.
As a preferred embodiment, the shell ontology is integrally formed with positioning column above-mentioned, variable weights and card slot.
The beneficial effects of the utility model are: the bolt passes through the location hole of pcb board and screw hole cooperation is attached to and determines
On the column of position, the lug boss is stuck in the positioning hole of pcb board, is so also able to achieve it is not necessary that limit bone is arranged on shell ontology
Positioning to pcb board reduces die cost, reduces the production cost of shell；Since the positioning of pcb board only needs positioning column and bolt
Cooperation is realized, the positioning to pcb board is so also able to achieve in accommodating space again small shell, and the scope of application is more extensive.
Detailed description of the invention
Fig. 1 is the exploded view of the embodiment of the utility model；
Fig. 2 is the cross-sectional view of the embodiment of the utility model.
In figure: 1- shell ontology, 2- positioning column, 3- screw hole, 4- lug boss, 5- guide ramp, 6- variable weights, 7- card slot,
8- bolt, 9-PCB plate, 91- location hole, 92- convex block.
Specific embodiment
The structural principle of the utility model and working principle are described in further detail with reference to the accompanying drawing.
As shown in FIG. 1 to FIG. 2, a kind of shell convenient for pcb board positioning, including shell ontology 1 and bolt 8, the shell ontology 1
It is equipped with positioning column 2, the positioning column 2 is axial to offer screw hole 3, and the upper surface of the positioning column 2 is formed with lug boss 4,
The bolt 8 passes through the location hole of pcb board 9 and the cooperation of screw hole 3 is attached on positioning column 2, and the lug boss 4 is stuck in pcb board 9
Location hole 91 in.
As a preferred embodiment, the height of the lug boss 4 is less than the thickness of pcb board 9.
As a preferred embodiment, the height of the lug boss 4 is 0.6-0.75 times of 9 thickness of pcb board, such lug boss
4 just can be stuck in the location hole of pcb board 9, and centainly fixed effect is played to pcb board 9, enable 9 fast locking of pcb board in fixed
On the column 2 of position, the efficiency that pcb board 9 is packed into shell ontology is improved.
As a preferred embodiment, the lug boss 4 is protruding circular ring.
As a preferred embodiment, the lug boss 4 is equipped with the guide ramp 5 tilted down from the outside to the core, and guiding is oblique
The setting in face 5 enables bolt 8 to be slides quickly into screw hole, further increases packaging efficiency.
As a preferred embodiment, the shell ontology 1 is equipped with variable weights 6, and one end of the variable weights 6 and positioning column connect
It connects, the other end of the variable weights 6 is connect with 1 inner wall of shell ontology, and the upper surface of the variable weights 6 is a flat surface, the plane
It is butted on the lower surface of pcb board 9.
As a preferred embodiment, 1 inner wall of shell ontology is equipped with the card slot 7 being adapted to 9 leading protrusions 92 of pcb board, card
The setting of slot 7 and variable weights 6 is able to achieve the quick positioning to pcb board 9.
As a preferred embodiment, the shell ontology 1 is integrally formed with positioning column 2 above-mentioned, variable weights 6 and card slot 7.
It should be noted that the lug boss not necessarily protruding circular ring, or the quantity of convex block, the convex block is big
In or be equal to 3, multiple convex blocks are circumferentially set to outside screw hole.
The beneficial effects of the utility model are: the bolt passes through the location hole 91 of pcb board 9 and the cooperation of screw hole 3 locks
In on positioning column 2, the lug boss 4 is stuck in the location hole 91 of pcb board 9, so it is not necessary that limit is arranged on shell ontology 1
