Description

Technical Field

The utility model relates to the technical field of connectors connected with PCBs, in particular to a connector, a connector fixing assembly and an electronic control unit.

Background

Connectors have a very critical role in PCB circuit boards, which are mainly important elements for providing current transmission. There are two main ways to mount the connector to the PCB, surface mount and through-hole solder mounting, respectively, to mount the connector to the PCB through pin pads or pin through holes.

The existing vehicle-mounted ECU (Electronic Control Unit, electronic control unit, also called "car computer", "vehicle-mounted computer", etc.) connector comprises a connector housing and a PIN needle. The PIN needle is used for functioning as a bridge between the blocked or isolated circuits in the circuit and carrying the tasks of current or signal transmission.

When the existing connector housing is connected with the PCB, only a single mounting mode, i.e., only a surface mounting mode or a through hole mounting mode is supported. Even if the mechanical structures of the two connector housings of different mounting modes are similar, the surface mounting mode and the through hole mounting mode cannot be supported simultaneously, i.e. the connector has low applicability. For connectors with the same number and size of PIN PINs, additional purchase and separate development of a connector shell are required for the project, so that the cost is high, and the development time node easily affects the whole project process.

Therefore, the existing connector does not support various mounting modes, and has low applicability.

The connector of claim 1, wherein said connector housing is provided with a boss on each side of a plurality of said PIN needles in said transverse direction, each of said bosses extending in said longitudinal direction, said first positioning portion being provided on each of said bosses, and a vertical distance from each of said bosses to said first surface in said longitudinal direction being less than or equal to a vertical distance from an outer side of said PIN needle to said first surface.

3. The connector of claim 2, wherein a difference between a perpendicular distance of each of the bosses to the first surface and a perpendicular distance of an outer side of the PIN needle to the first surface in the longitudinal direction is less than 1mm.

4. A connector according to claim 3, wherein at least two of said first positioning portions are provided, and wherein two of said first positioning portions are provided on said convex portions on both sides of a plurality of said PIN needles in said lateral direction in a staggered manner.

5. The connector of any one of claims 1 to 4, wherein the connector housing is provided with a second positioning portion provided vertically along the vertical direction on an outer side wall of a second surface of the connector housing, the second surface extending along the longitudinal direction, the second surface being perpendicular to the first surface, the second positioning portion being for insertion into a positioning hole on the PCB.

6. The connector of claim 5, wherein the second detent has a dimension in the vertical direction that is less than a dimension difference in the vertical direction between the PIN needle and the second surface.

7. The connector according to any one of claims 1 to 4, 6, wherein the projection of the first positioning portion in the longitudinal direction is any one of a circle, an ellipse, a polygon, or an irregularity, and/or the projection of the second positioning portion in the vertical direction is any one of a circle, an ellipse, a polygon, or an irregularity.

8. A connector securing assembly, comprising: the PCB and the connector of any one of claims 1 to 7, wherein,

the PCB is provided with a positioning hole along the vertical direction, wherein the vertical direction is the thickness direction of the PCB;

the connector comprises a first positioning part and a second positioning part, wherein the first positioning part or the second positioning part is used for being connected with the positioning hole so as to enable the connector to be connected with the PCB.

9. The connector securing assembly as recited in claim 8, wherein the connector includes a connector housing including a first surface extending in the vertical direction, the first locating portion being provided on an outer sidewall of the first surface in a longitudinal direction perpendicular to the vertical direction, a dimension of the first locating portion in the longitudinal direction being equal to a dimension of the locating hole in the vertical direction.

10. The connector securing assembly as claimed in claim 9, wherein the connector housing includes a second surface extending in the longitudinal direction, the second surface being perpendicular to the first surface, the second locating portion being provided in the vertical direction on an outer side wall of the second surface, the second locating portion having a dimension in the vertical direction equal to a dimension of the locating hole in the vertical direction.

11. The connector securing assembly as claimed in claim 10, wherein the locating hole is adapted to the shape of the first locating portion or the second locating portion, the locating hole being projected in the vertical direction as any one of a circle, an ellipse, a polygon, or an irregular shape.

12. An electronic control unit comprising a connector securing assembly according to any one of claims 8 to 11.
