For above-mentioned defect, this patent proposes a kind of ECU plug of improvement.
Summary of the invention
The purpose of this utility model is to overcome shortcoming and defect of the prior art, and a kind of ECU plug is provided, and it both can improve the high problem of matching used ECU upper cover punching press fraction defective with it, adopted again the simple contact pin of production technology.
To achieve these goals, the utility model adopts following technical scheme:
ECU plug, be connected with ECU shell, comprise Access Division and the connecting portion for inserting for external connection device, the outer wall of Access Division connects the inwall of ECU shell accent, Access Division has the location notch for accommodating ECU up-cover positioning structure up-cover, and the front end of location notch is provided with the catch for stopping that location structure is pulled out forward, and the cross section of Access Division is trapezoidal, the side of Access Division and lower surface form included angle A, and the angular range of included angle A is 63 ° ± 3 °; ECU plug also comprises the contact pin of L-type, and one of contact pin for connecting external connection device, and the other end of contact pin passes connecting portion and is connected with the contact pin row who is placed in ECU shell.
Wherein, the angle of described included angle A is 64 °.
Wherein, the upper surface of described connecting portion is provided with five reinforcements.
Wherein, the width of described reinforcement is 2 ± 0.5 mm.
Wherein, the upper surface of described connecting portion is higher than the upper surface of Access Division, and the surface of Access Division is provided with for stopping upper cover mobile blend stop backward, and the outer surface of blend stop connects the inwall of ECU shell accent, and blend stop is positioned at the rear of draw-in groove.
Wherein, the height of described blend stop is 2 ± 0.5mm.
Wherein, described catch covers the accent of ECU shell.
Wherein, the location structure of described ECU upper cover is spacer.
The utility model beneficial effect: the angle of the included angle A that the side of the utility model Access Division and lower surface form is 63 ° ± 3 °, the angular range of angle is larger compared to existing technology, thereby the angular range of ECU shell accent is also larger, significantly reduce because of the upper cover punching press of angle too small generation herein bad; And the utility model adopts the contact pin of L-type, contact pin has compared to existing technology saved the bending of two places and has processed, and production technology is simpler, thereby has reduced the production cost of contact pin.

Embodiment
Referring to Fig. 1 to Fig. 5, below in conjunction with accompanying drawing, the utility model is described in detail.
ECU plug, comprise Access Division 1 and the connecting portion 2 for inserting for external connection device, the outer wall of Access Division 1 connects the inwall of ECU shell accent, Access Division 1 has the location notch 3 for accommodating ECU up-cover positioning structure up-cover, the front end of location notch 3 is provided with the catch 4 for stopping that location structure is pulled out forward, the cross section of Access Division is trapezoidal, and the side of Access Division 1 and lower surface form included angle A, and the angle of included angle A is 63 ° ± 3 °; ECU plug also comprises the contact pin 5 of L-type, and one of contact pin 5 for connecting external connection device, and the other end of contact pin 5 passes connecting portion 2 and is connected with the contact pin row who is placed in ECU shell.
The location structure of described ECU upper cover can be spacer, and common laminated structure, can coordinate ECU plug can not inwardly be promoted with catch 4 after insertion location notch, also can not pull out.Other location structure is also applicable to the present embodiment, as the contact-making surface location structure that is inclined-plane.
The nouns of locality such as the 'fornt', 'back' of the present embodiment, " left side ", " right side ", " interior ", " outward " be take grafting direction as reference direction, and inserted terminal is " front ".The cross section of the present embodiment is perpendicular to grafting direction.
The angular range of the included angle A that the side of the utility model Access Division 1 and lower surface form is 63 ° ± 3 °, the angular range of angle is larger compared to existing technology, thereby the angular range of ECU shell accent is also larger, significantly reduce because of the upper cover punching press of angle too small generation herein bad; And the utility model adopts the contact pin 5 of L-type, contact pin 5 has compared to existing technology saved the bending of two places and has processed, and production technology is simpler, thereby has reduced the production cost of contact pin 5.
Preferably, the angle of included angle A is 64 °, from actual production, sums up, and the ECU upper cover punching press fraction defective of this angle is minimum.
Because being plastic material, makes by ECU plug, cooling rear easy contraction, the dimensional stability of product is bad, causes just easily becoming flexible after its insertion ECU shell, the soundness that further impact is connected with ECU, the present embodiment is provided with five reinforcements 6 at the upper surface of connecting portion 2.Consider the volume of ECU plug, five reinforcements 6 have guaranteed the stability of product size preferably.And the width of reinforcement 6 is preferably 2 ± 0.5mm.
Further, the upper surface of connecting portion 2 is higher than the upper surface of Access Division 1, and the surface of Access Division 1 is provided with for stopping upper cover mobile blend stop 7 backward, and the outer surface of blend stop 7 connects the inwall of ECU shell accent, and blend stop 7 is positioned at the rear of draw-in groove.Because Access Division 1 needs to contact with accent inwall, thereby avoid connection-peg to rock in accent, so the height of blend stop 7 can not be too high, preferred altitude range is 2 ± 0.5mm.
The catch 4 of the present embodiment covers the accent of ECU shell, thereby avoids foreign object to insert and contact with the ECU placing in ECU shell from accent.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
