Description
Technical field
The present invention relates to the mounting structure of a kind of BMS product casing and PCB.
Background technology
In current BMS product, the installation great majority of PCB adopt the mode of fastened by screw, and the shortcoming of this mode is, BMS mainly uses on automobile, must have vibrations during running car, and long-term vibrations then may make the screw loosening of fixing PCB, even drop.When BMS works on power, the screw dropped due to vibrations play in housing of automobile, then may cause short circuit, and product function lost efficacy.
Have method to propose and establish at cap the PCB fixed leg stretched out downwards, Internal PCB is just in time pushed down and is fixed by it.The shortcoming of this mode is: when 1) product is vertically fixed, if pull down shell, then inner PCB can directly drop; 2) just in time pushed down by PCB to fixed leg, firm being fixed in housing of PCB can not be rocked, then the precision of fixed leg height needs very high, and the manufacturing cost of corresponding housing can raise.
Summary of the invention
Screw is there is and easily drops and cause short circuit in the present invention in order to solve existing fastened by screw formula BMS product casing and the supporting mounting structure of PCB, and solve existing fixing pillar BMS product casing and the supporting mounting structure of PCB and exist when pulling down shell, pcb board can directly drop, the problem high to the required precision of female post height that presses, thus proposes a kind of BMS product casing and the supporting mounting structure of PCB.
BMS product casing and the supporting mounting structure of PCB, it comprises press female post 2 and the post 5 that presses; It is characterized in that, it also comprises spring 3;
The closed end of female post 2 of pressing vertically is mounted in the lower surface of the upper cover 1 of BMS product casing; The post 5 that presses is made up of a cylinder and No. two cylinders, and the internal diameter of a described cylinder is less than the internal diameter of No. two cylinders; A cylinder is positioned at the top of No. two cylinders, and the lower end of a cylinder is coaxially fixedly connected with the upper end of No. two cylinders;
The lower end of No. two cylinders is vertically mounted in the upper surface of the base 6 of BMS product casing;
Female post 2 that presses coaxially is arranged with the post 5 that presses;
Pcb board 4 has installing hole, and the internal diameter of this installing hole is greater than the internal diameter of a cylinder and is less than the internal diameter of No. two cylinders; A described cylinder is through this installing hole, and the lower surface of the upper surface of No. two cylinders contact pcb board 4;
The internal diameter of spring is greater than the internal diameter of a cylinder and is less than the internal diameter of No. two cylinders; Described spring housing is connected on a cylinder;
The opening inside diameter of female post 2 of pressing is greater than the internal diameter of a cylinder and is less than the internal diameter of No. two cylinders;
Described female post 2 that presses is enclosed within the outside of spring, and described in press female post 2 openend contact pcb board 4 upper surface.
The mode that the present invention uses the post that presses to coordinate with female post that presses fixes PCB, eliminates the operation that PCB installed by stubborn screw, saves manpower and materials; Avoid screw loosening to drop the consequence caused; Facilitate installation and the dismounting of PCB, and when product is vertically fixed, pull down shell, inner PCB can not drop.
Add spring during installation, make to reduce the required precision of female post height that presses, thus reduce manufacturing cost; And product shake environment in use time, the cushioning effect that spring can play, can protect parts on pcb board injury-free effectively.

Fig. 2 is assembling schematic diagram of the present invention;
Embodiment
The mounting structure that embodiment one, BMS product casing and PCB are supporting, it comprises press female post 2 and the post 5 that presses; It also comprises spring 3;
The closed end of female post 2 of pressing vertically is mounted in the lower surface of the upper cover 1 of BMS product casing; The post 5 that presses is made up of a cylinder and No. two cylinders, and the internal diameter of a described cylinder is less than the internal diameter of No. two cylinders; A cylinder is positioned at the top of No. two cylinders, and the lower end of a cylinder is coaxially fixedly connected with the upper end of No. two cylinders;
The lower end of No. two cylinders is vertically mounted in the upper surface of the lower cover 6 of BMS product casing;
Female post 2 that presses coaxially is arranged with the post 5 that presses;
Pcb board 4 has installing hole, and the internal diameter of this installing hole is greater than the internal diameter of a cylinder and is less than the internal diameter of No. two cylinders; A described cylinder is through this installing hole, and the lower surface of the upper surface of No. two cylinders contact pcb board 4;
The internal diameter of spring is greater than the internal diameter of a cylinder and is less than the internal diameter of No. two cylinders; Described spring housing is connected on a cylinder;
The opening inside diameter of female post 2 of pressing is greater than the internal diameter of a cylinder and is less than the internal diameter of No. two cylinders;
Described female post 2 that presses is enclosed within the outside of spring, and described in press female post 2 openend contact pcb board 4 upper surface.
The difference of the BMS product casing described in embodiment two, this embodiment and embodiment one and the supporting mounting structure of PCB is, the integral piece that the post 5 that presses is made up of a cylinder and No. two cylinders.
The difference of the BMS product casing described in embodiment three, this embodiment and embodiment one or two and the supporting mounting structure of PCB is, in its natural state, its length is greater than the height of female post 2 that presses to spring 3.
In the present invention:
On the base 6 of BMS product casing embedded post 5, the BMS product casing that presses upper cover 1 on embedded female post 2 that presses.Press post 5 for stepped ramp type, and thinner section divides column diameter corresponding with pcb board 4 reserving installation hole diameter, and it is suitable for passing with pcb board 4; Thicker part divides column diameter larger than pcb board 4 reserving installation hole diameter, with pcb board 4 can steadily placed on it be suitable.The diameter of spring 3 divides column diameter corresponding with post 5 thinner section that presses, and height is a little more than female post 2 that presses.The internal diameter of female post 2 of pressing is a bit larger tham the diameter that post 5 thinner section that presses divides cylinder, is suitable can put into spring 3 again.
When installing pcb board 4, the installing hole that pcb board 4 is reserved directly aims at the post 5 that presses, and puts into pcb board 4, then spring 3 is placed on place pcb board 4 press on post 5, the post 5 that presses aimed at by female post 2 that finally will press, and loads the upper cover 1 of BMS product casing.By screw 7, the upper cover 1 of BMS product casing and the base 6 of BMS product casing are installed fixing, thus ensure pcb board 4 install between post 5 at the female post 2 and pressing of pressing firm.
The effect of spring 3 is: even if PCB 4 is not fitted in centre with the post 5 that presses by female post 2 that presses completely, spring 3 also can make gap fully support, and makes pcb board 4 fixed, and when product uses in the environment shaken, spring 3 can play the effect of buffering.
