Abstract

Provided is an electronic controller which enables an opening direction of a connector to be set along an electronic circuit board. The electronic controller includes first guiding projections ( 7 a ) and second guiding projections ( 7 b ) formed on a cover ( 2 ), and first guiding grooves ( 8 a ) to be brought into engagement with the first guiding projections ( 7 a ) and second guiding grooves ( 8 b ) to be brought into engagement with the second guiding projections ( 7 b ), which are formed on pin headers ( 4 ). The first guiding projections ( 7 a ) and the second guiding projections ( 7 b ) move respectively along the first guiding grooves ( 8 a ) and the second guiding grooves ( 8 b ). As a result, the pin headers ( 4 ) turn to be assembled to housings ( 14 ).

First claim

What is claimed is:

1. An electronic controller, comprising:
an electronic circuit board having electronic components mounted thereon;
a casing for receiving the electronic circuit board therein, comprising at least a first casing member and a second casing member; and
a connector to be electrically connected to an external device, wherein:
the connector comprises:
a pin header pre-fixed onto the electronic circuit board and including a plurality of terminals whose base end portions are electrically connected to the electronic circuit board, the plurality of terminals being inserted into a pedestal; and
a housing provided integrally with the first casing member, which surrounds distal end portions of the plurality of terminals extending in a direction along the electronic circuit board;

one of the pin header and the first casing member comprises a guiding projection, whereas another of the pin header and the first casing member comprises a guiding portion to be brought into engagement with the guiding projection; and
the guiding projection moves along the guiding portion relative thereto to turn the pin header pre-fixed onto the electronic circuit board to assemble the pin header to the housing.

2. An electronic controller according to claim 1 , wherein:
the guiding projection comprises a pair of guiding projections; and
the pair of guiding projections respectively slide in a pair of the guiding portions formed in a linear fashion so as to be opposed to each other in nonparallel.

3. An electronic controller according to claim 1 , wherein:
the guiding projection comprises a pair of guiding projections; and
the pair of guiding projections respectively slide in a pair of the guiding portions formed to extend in a curved manner so as to be opposed to each other at an equal distance.

4. An electronic controller according to claim 1 , wherein:
the guiding projection is formed in a curved shape; and
the guiding projection slides in the single guiding portion formed continuously in a curved shape.

5. An electronic controller according to claim 1 , wherein the guiding portion is formed on each of side-surface portions formed on both sides of the pin header along a direction in which the plurality of terminals extend.

6. An electronic controller according to claim 1 , wherein the guiding projection is formed on each of side-surface portions formed on both sides of the pin header along a direction in which the plurality of terminals extend.

7. An electronic controller according to claim 1 , wherein:
fixing projections projecting inward are formed to a terminal end portion of the guiding portion, which is closed on a side opposite to an open start end portion; and
the guiding projection is fixed by the fixing projections over which the guiding projection has passed.

8. An electronic controller according to claim 1 , wherein:
fixing projections projecting inward are formed to a terminal end portion of the guiding portion, which is closed on a side opposite to an open start end portion; and
the guiding projection is fixed by the fixing projections over which the guiding projection has passed.

9. A method of manufacturing the electronic controller according to claim 1 , the method comprising:
mounting the pin header onto the electronic circuit board;
bringing the guiding projection into engagement with the guiding portion in a state in which the electronic circuit board is inclined with respect to the first casing member; and
assembling the electronic circuit board to the first casing member by turning the electronic circuit board in a state in which the guiding projection is held in engagement with the guiding portion to simultaneously turn the pin header so as to assemble the pin header to the housing.
