Abstract
The utility model provides a PCB fixing structure used in two-in-one modules. The PCB fixing structure comprises a guide rail positioning structure and a fixing structure; the guide rail positioning structure is composed of guide posts and grooves, wherein the guide posts and the grooves match with each other and are respectively arranged on a main body base and a PCB; the fixing structure is composed of a square column and a square hole, wherein the square column and the square hole match with each other and are respectively arranged on the main body base and the PCB; and the PCB and the main body base are positioned in a guiding way through the cooperation between the guide posts and the grooves, and the square column passes through the square hole to be positioned at the same time. According to the embodiment of the utility model, a high-reliability fixing method is formed after the PCB is tightly limited on the main body base through the central square column and a dual-guide-rail positioning method and then the main body base and an upper cover are combined and extruded. Larger amplitude of the PCB can be prevented, the possibility that the PCB and a vehicle vibrate to generate resonance can be eliminated, and the reliability of physical and electrical properties of the PCB can be ensured.
Description
Technical field
The utility model relates to the connector technique field, relate in particular to a kind of pcb board fixed structure, be applied to vehicle-mounted USB(Universal Serial Bus) connector and audio connector be through PCB(Printed Circurt Board) the two-in-one module that forms of plate switching.
Background technology
At present, vehicle USB connector and audio connector all are modes that level is inserted the plastic cement main body through the pcb board fixed structure of the two-in-one module of pcb board switching formation on the market.
There is following shortcoming in the pcb board fixed structure of this two-in-one module: because there is up and down larger gap in pcb board, when vibrating for a long time in the vehicle operating, very large amplitude appears in pcb board, and easy and Vehicular vibration resonates, thereby cause pcb board to break, the electric property failure phenomenon.Thereby be necessary this pcb board fixed structure is improved.
Summary of the invention
The purpose of this utility model is to provide a kind of pcb board fixed structure that is applied to two-in-one module, avoids pcb board to occur than large amplitude in the vehicle movement process, stops pcb board and Vehicular vibration the phenomenon that resonance causes pcb board to break occurs.
The purpose of this utility model is achieved through the following technical solutions:
A kind of pcb board fixed structure that is applied to two-in-one module, described two-in-one module comprises main base, pcb board and loam cake, and pcb board is installed between main base and the loam cake, and this pcb board fixed structure comprises guide rail positioning structure and fixed structure;
Described guide rail positioning structure is comprised of suitable lead and groove, and lead is located on the described main base, the groove correspondence is located on the described pcb board, and perhaps lead is located on the described pcb board, the groove correspondence is located on the described main base;
Described fixed structure, formed by suitable outstanding square column and square opening, square column is located at that lead is located on the described main base, the square opening correspondence is located on the described pcb board, and perhaps square column is located on the described pcb board, the square opening correspondence is located on the described main base;
Described pcb board and main base are by lead and groove fit guide-localization, and the while square column is passed square opening and positioned.
Preferably, described guide rail positioning structure comprises two pairs of suitable leads and groove, and this guide rail positioning structure and described fixed structure form the triangle location structure.
Compared with prior art, the utility model embodiment has following beneficial effect:
Among the utility model embodiment, the pcb board fixed structure is to adopt a central square post in conjunction with two guide rail locate modes that pcb board is closely spacing on main base, be combined extruding with loam cake through main base again, form the fixed form of high reliability, avoided pcb board to occur than large amplitude, stop the possibility that resonance occurs for pcb board and Vehicular vibration, thereby guaranteed the reliability of pcb board physics and electric property.
Description of drawings
Fig. 1 is the explosive view of two-in-one module among the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Usually, vehicle USB connector and audio connector mainly comprise through the two-in-one module that the pcb board switching forms: main base 1, loam cake 2, pcb board 3; Pcb board 3 is located in the main base 1 of packing into, and loam cake 2 is pressed in the main base 1.
In the present embodiment, the pcb board fixed structure that is applied to above-mentioned two-in-one module mainly comprises following part: guide rail positioning structure and fixed structure.
Consult shown in Figure 1ly, guide rail positioning structure comprises: be located at two lead 1-2 of the protrusion on the main base 1, be located at two groove 3-2 on the pcb board 3; Position and the shape of lead 1-2 and groove 3-2 are suitable, to form two guide rails location.
Fixed structure comprises: be located at the square opening 3-1 of center on the pcb board 3, and the corresponding square column 1-1 that gives prominence on the main base 1 that is located at; Position and the shape of square column 1-1 and square opening 3-1 are suitable, so that square column 1-1 can pass square opening.
In the present embodiment, the assembling mode of having used the two-in-one module of above-mentioned pcb board fixed structure is:
1) pcb board 3 is located in the main base 1 of packing into, the protrusion lead 1-2 of main base 1 cooperates guide-localization with the groove 3-2 of pcb board 2 in the assembling process, the square column 1-1 of main base 1 passes the square opening 3-1 of pcb board 3, forms reliable triangle locate mode with this.
2) loam cake 2 is pressed in the main base 1, can main base 1 and loam cake 2 be combined by two point elasticity oblique top interference fit, 2 interference engagement and two guide rail locate mode.This moment, pcb board was squeezed in middle reliably by main base 1 and loam cake 2.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
