Detailed Description

The utility model will be described in detail below with reference to the drawings and detailed description thereof.

Referring to fig. 1-3, an automobile controller structure comprises an upper shell 10 and a lower shell 30, wherein the upper shell 10 and the lower shell 30 are fixed by bolts, a sealing ring 11 is arranged at the contact position of the upper shell 10 and the lower shell 30, a PCBA board 20 is arranged in a space between the upper shell 10 and the lower shell 30, a first board terminal connector 22, a second board terminal connector 21 and an ethernet connector 23 are arranged on the PCBA board 20, a wire harness fixing bracket 32 is arranged on the lower shell 30 for fixing a wire harness, and a waterproof ventilation valve 31 is arranged on the lower shell 30.

PCBA is an acronym for english Printed Circuit Board Assembly.

The first board terminal connector 22 and the second board terminal connector 21 are both self-shielded exposed connectors, a first exposed area 33 and a second exposed area 34 are provided on the lower housing 30, the first board terminal connector 22 is exposed from the first exposed area 33, and the second board terminal connector 21 is exposed from the second exposed area 34.

As shown in fig. 2 to 5, in order to prevent erroneous insertion, the electrical component layout shape of the first board terminal connector 22 after rotating 180 ° is identical to the electrical component layout shape of the second board terminal connector 21, the lower case 30 is provided with anti-reflection posts 35 in both the side regions of the first exposed region 33 and the second exposed region 34, the anti-reflection posts 35 include a-posts and B-posts, and the positional relationship between the anti-reflection posts 35 and the first exposed region 33 is identical to the positional relationship between the anti-reflection posts 35 and the second exposed region 34.

Referring to fig. 4, the two terminals are properly connected to the first board terminal connector 22 and the second board terminal connector 21.

Referring to fig. 5, if a terminal is erroneously connected to either the first board terminal connector 22 or the second board terminal connector 21, the anti-reflection post 35 can prevent, specifically:

s1, the error of the direction of the correct terminal can be prevented

When the terminal 90 structural member rotates, the terminal can collide with the anti-reflection post 35, and cannot rotate in place and be effectively locked.

S2, a terminal connection harness termination plug capable of preventing errors

When the wire harness terminal connector 01 and the wire harness terminal connector 02 are misplaced, the wire harness terminal connector cannot be plugged in place due to the asymmetric design of terminals during board arrangement, and misplacement can be prevented.

The working principle is as follows:

the installation step comprises the following steps:

the first step: first, a waterproof and breathable valve 31 (with a protective rubber ring) is attached to the lower case 30;

and a second step of: fixing the harness fixing bracket 20 to the lower case corresponding position for harness fixing;

and a third step of: the PCBA board 20 is placed in the lower housing 30 and screwed, wherein the board end connectors, the Ethernet connectors are self-contained with protective rubber rings:

fourth step: the sealing ring 11 is placed in the lower shell machining groove, and then the upper shell and the lower shell are fixed together by using screws. The utility model is characterized in that:

s1, considering the protection design, the product meeting the requirement of IP6K9K is required, the compressed rubber ring is required to be considered between any two parts to play a role in protection, and the roughness and the flatness of the contact surface are required to be ensured as much as possible.

S2, starting from PCBA cloth plates at the beginning of product design, arranging the same connectors in an anti-reverse design manner; the problem that the anti-reverse installation effect can be achieved only through subjective judgment of operators in the later period, such as visibility, touch and the like, is avoided.

S3, error plug loss caused by errors due to artificial factors is avoided.

S4, bolt fixing can improve working efficiency, reduce man-hour waste and reduce cost.

See the prior art for further content.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several changes and modifications can be made without departing from the general inventive concept, and these should also be regarded as the scope of the utility model.
