Abstract
The utility model discloses an automobile instrument lamp chamber capable of preventing wrong installation. Two locating columns connected with circuit boards are arranged on the automobile instrument lamp chamber. Locating holes matched with the locating columns are disposed on the circuit boards. The diameters of the two locating columns are different, and the diameters of the locating holes on the corresponding circuit boards are also different. By means of the technical scheme, the two locating columns of the automobile instrument lamp chamber are changed into the locating holes having different diameters and different sizes and corresponding to the circuit boards, distinguishing becomes easy, and installation of the automobile instrument lamp chamber in a correct direction is guaranteed. Accordingly, correct installation of liquid crystal displays is guaranteed, and rework rate of the liquid crystal displays due to wrong installation is reduced.
Description
Technical field
The utility model relates to automobile instrument, and specifically, the utility model relates to a kind of anti-misloading automobile instrument lamp house.
Background technology
The lamp house of orthodox car instrument is used to support LCDs; LCDs is to press on lamp house; The contact pin of LCDs passes wiring board, and fixing with the wiring board welding, and lamp house is connected PCB surface; Have two reference columns that diameter is identical on the lamp house, at the corresponding pilot hole that cooperates with reference column that is provided with of PCB surface.The shortcoming that this structure exists is the possibility that lamp house has installation to misplace; Because lamp house is the same with the diameter of two reference columns that wiring board is installed, the diagonal angle is symmetrically distributed, and is not easy to distinguish which pilot hole on the concrete corresponding line plate of each reference column surface; If the lamp house direction misplaces; Can cause the LCDs direction also to misplace, LCDs can not be worked, cause and do over again.
The utility model content
The utility model technical matters to be solved provides a kind of anti-misloading automobile instrument lamp house that can install by correct direction.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of automobile instrument lamp house of anti-misloading; Which is provided with two reference columns that are connected with wiring board; Be provided with the pilot hole that cooperates with this reference column in the circuit board, the diameter of said two reference columns differs, and the diameter of the pilot hole on the corresponding said wiring board also differs.
The diameter of said two reference columns is respectively 1.5mm and 2.5mm.
The utility model adopts technique scheme; Change two reference columns of lamp house into different-diameter; Respectively the pilot hole not of uniform size on the corresponding line plate is distinguished easily, guarantees that lamp house can install by correct direction; Thereby guarantee the correct installation of LCDs, reduce LCDs because of adorning wrong rework rate.
Description of drawings
Fig. 1 is the mounting structure synoptic diagram of the utility model lamp house;
Fig. 2 is the structural representation of the lamp house of the utility model;
Mark among the above-mentioned figure is: 1, LCDs; 2, lamp house; 3, wiring board; 4, contact pin; 5, reference column.
Embodiment
The automobile instrument lamp house of a kind of anti-misloading of the utility model is used to support the LCDs 1 of automobile instrument, and LCDs 1 is to press on lamp house 2; The contact pin 4 of LCDs 1 passes wiring board 3; And fixing with wiring board 3 welding, lamp house 2 is connected wiring board 3 surfaces, and concrete structure is as shown in Figure 1; Lamp house 2 is provided with two reference columns 5 that are connected with wiring board 3, on wiring board 3, is provided with the pilot hole that cooperates with this reference column 5.In order to ensure the correct installation of lamp house 2, prevent that dress is wrong, as shown in Figure 2, the diameter of two reference columns 5 of lamp house 2 differs, and the diameter of the pilot hole on the corresponding online road plate 3 also differs.Adopt this structure, change two reference columns 5 of lamp house 2 into different-diameter, pilot hole not of uniform size on the corresponding line plate 3 respectively; Distinguish easily; Guarantee that lamp house 2 can install by correct direction, thereby guarantee the correct installation of LCDs 1, reduce LCDs 1 because of adorning wrong rework rate.
The diameter of two concrete reference columns 5 is respectively: one is 1.5mm, and another is 2.5mm.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the concrete realization of the utility model does not receive the restriction of aforesaid way; As long as adopted the method design of the utility model and the improvement of the various unsubstantialities that technical scheme is carried out; Or the design of the utility model and technical scheme are directly applied to other occasion without improving, all within the protection domain of the utility model.
Claims (2)
1. the automobile instrument lamp house of an anti-misloading; Which is provided with two reference columns that are connected with wiring board; Be provided with the pilot hole that cooperates with this reference column in the circuit board; It is characterized in that: the diameter of said two reference columns differs, and the diameter of the pilot hole on the corresponding said wiring board also differs.
2. the automobile instrument lamp house of anti-misloading according to claim 1, it is characterized in that: the diameter of said two reference columns is respectively 1.5mm and 2.5mm.
