Abstract
The utility model discloses a kind of pneumatic actuator lid, comprise housing, circuit board and connector, described connector is provided with inserting terminal, described circuit board is provided with corresponding terminal insertion hole, in housing, be provided with the mounting groove of mounting circuit boards, it is characterized in that: described circuit board is provided with at least two positioning holes, in described mounting groove, be provided with locating face, and locating face is provided with the positioning part corresponding with positioning hole.
Description
Technical field
The utility model relates to a kind of pneumatic actuator lid, particularly a kind of for the lid on the pneumatic actuator on turbosupercharger exhaust gas by-pass valve.
Background technique
Pneumatic actuator is with atmospheric pressure, to drive the actuating device of keying or regulating valve, pneumatic actuator on turbosupercharger exhaust gas by-pass valve is the main parts size on exhaust gas by-pass valve, exhaust gas by-pass valve is by regulating the pressure reduction of boost pressure and atmospheric pressure to control the motion of final controlling element inner membrance plate valve, thereby regulate the aperture of wastegate, reach the object that regulates suction pressure value.
The lid of this final controlling element is mainly comprised of three parts, comprises the connector with terminal, circuit board and housing.Pressure in final controlling element mainly receives signal by the pressure transducer on circuit board, then by connector, transmits signal to ECU, and ECU is again according to receiving the aperture that signal is controlled wastegate.Three parts of final controlling element install by certain positioning relation.The edge by circuit board in assembling process of lid before positions with face corresponding on housing, but due to the defect of circuit board cutting technique and the defect of plastics forming technique itself, cannot guarantee the smooth of locating face.Therefore often occur circuit board install not in place, cause connector installs not Shang or installation process in damage the situation of connector upper terminal, cause a large amount of defective productss, increased cost of goods manufactured, and upper cover and the easy installation of lower cover not in place.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of circuit board with positioning hole, thereby can accurately circuit board be installed to suitable position.
The utility model solves the technological scheme that its technical problem adopts:
A kind of pneumatic actuator lid, comprise housing, circuit board and connector, described connector is provided with inserting terminal, described circuit board is provided with corresponding terminal insertion hole, in housing, be provided with the mounting groove of mounting circuit boards, it is characterized in that: described circuit board is provided with at least two positioning holes, in described mounting groove, be provided with locating face, and locating face is provided with the positioning part corresponding with positioning hole.
Described locating face is the internal face of mounting groove.
The beneficial effects of the utility model are: the utility model positions by the mounting-positioning holes on circuit board, because the distance that can realize between mounting-positioning holes and terminal insert port is fixed, in installation process, just only need the insertion distance of the positioning hole on control circuit board just can accurately circuit board be installed to suitable position, then directly terminal is inserted.Facilitated like this installation of connector and circuit board in final controlling element lid production process to improve the yield of product, effectively prevented defective products, the generation of waste product, has saved cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the explosive view of the utility model upper cover,
Fig. 2 is the three-dimensional view of the utility model upper cover,
Fig. 3 is the three-dimensional view of the utility model lower cover.
Embodiment
Referring to figs. 1 through 3, the utility model discloses a kind of pneumatic actuator lid, comprise housing 1, circuit board 2 and connector 3, described connector 3 is provided with inserting terminal 4, described circuit board 2 is provided with corresponding terminal insertion hole 5, described terminal insertion hole 5 is provided with three, and these three terminal insertion hole 5 conllinear, in housing 1, be provided with the mounting groove 6 of mounting circuit boards 2, circuit board 2 is provided with two positioning holes 7, in described mounting groove 6, be provided with locating face, and locating face is provided with the positioning part (not shown) corresponding with positioning hole 7, distance between this positioning part and terminal insert port 8 is constant, thereby when circuit board 2 inserts from mounting groove 6, as long as the positioning hole 7 on circuit board 2 moves to the position of corresponding positioning part, with regard to the distance that is equivalent between terminal insert port 8 and positioning hole 7, be constant, inserting terminal 4 position of corresponding terminal patchhole 5 just in time now, thereby in installation process, just only need the insertion distance of the positioning hole 7 on control circuit board 2 just can accurately circuit board 2 be installed to suitable position, then directly terminal is inserted.Facilitated like this installation of connector 3 and circuit board 2 in final controlling element lid production process to improve the yield of product, effectively prevented defective products, the generation of waste product, has saved cost.
Particularly, described positioning hole 7 is circular hole, and positioning part is cylinder, and this cylinder can insert in circular hole and coordinate location, above-mentioned selection are convenient to processing and manufacture, but other section form also can be selected in positioning hole 7 and positioning part; And described locating face is the internal face of mounting groove 6, simplified structure is convenient in above-mentioned setting.
As shown in the figure, described housing comprises upper cover 13 and lower cover 9, lower cover 9 is provided with positioning block 10, it is two that positioning block 10 is symmetrical arranged, and described positioning block 10 is rectangular block, and the concrete shape of positioning block 10 does not form the restriction to this patent certainly, the cross section of positioning block 10 also can be trigonometric form or regular hexagon etc., upper cover 13 is provided with the locating slot 11 coordinating with this positioning block 10, and when rectangular block and locating slot 11 are chimeric time, upper cover 13 accurately fastens with lower cover 9.The concrete structure of locating slot 11 is as described below: on upper cover 13 outer walls, be relatively provided with L shaped tabs 12, described locating slot 11 consists of the gap of 12 of two tabs, tabs 12 is L shaped, thereby tabs 12 has certain distance with upper cover 13 outer walls, when lower cover 9 that upper cover 13 fastens, because thering is certain space between tabs 12 and upper cover 13 outer walls, can avoid lower cover 9 edges to move and cause obstacle.
Certainly, the above-mentioned just description of instantiation, this structure can also adopt at upper cover 13 outer walls positioning block 10 is set, and the mode of establishing locating slot 11 on lower cover 9.
This structure is coordinated and realizes fool-proof design with positioning block 10 by the locating slot 11 being arranged on upper cover 13, lower cover 9, guarantees that upper cover 13, lower cover 9 accurately fasten, thereby reduces gas leakage and the problem such as electrical connector angle is bad, not only assembling simply, and reliable in structure.
A kind of pneumatic actuator lid above the utility model embodiment being provided, be described in detail, applied specific case herein principle of the present utility model and mode of execution are set forth, above embodiment's explanation is just for helping to understand method of the present utility model and core concept thereof; , for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model meanwhile.
