Example one

In the embodiment, as shown in fig. 2-4, the housing includes an upper cover 1 and a lower cover 2 that are connected to each other, in order to ensure that there is enough space between the upper cover 1 and the lower cover 2 to accommodate a wire harness, instead of using the design of two pairs of bosses in the prior art, three bosses for placing a PCB 3 are provided in the lower cover 2, and in order to ensure that the PCB is stably placed, the bosses are distributed triangularly, and include a first boss 21 and a second boss 22 that are close to a connector port 4, and a third boss 23 that is far away from the connector port 4, and the first boss 21 and the second boss 22 may be symmetrically distributed on both sides of the third boss 23, so as to further improve the stability of the bosses supporting the PCB, specifically, the first boss 21 and the second boss 22 are provided on both side edges of the lower cover 2, and the third boss 23 is provided in the center of the lower cover 2. During the installation, 1 both sides edge of upper cover pushes up respectively and supports on first boss 21, second boss 22, for guaranteeing that upper cover 1 and lower cover 2 can be better press from both sides tight PCB board 3 to carry out the subregion to inside pencil, strengthen the joint strength between upper cover 1 and lower cover 2 simultaneously, upper cover 1 central inboard corresponds third boss 23 position and extrudees down and form fourth boss 14, third boss 23 and fourth boss 14 push up respectively and support at 3 both sides centers of PCB board, and press from both sides tight PCB board 3.

Further, the first boss 21 and the second boss 22 respectively comprise a high column 25 and short columns 24 distributed on two sides of the high column 25 along the line beam running direction, the high column 25 is in a semi-cylindrical shape, the short columns 24 are in a rectangular shape, and the high column 25 and the short columns 23 are formed together with the lower cover 2 through injection molding. The third bosses 23 and the fourth bosses 14 are respectively provided on the lower cover bead 26 and the upper cover bead 13 distributed in the harness direction.

Further, for guaranteeing the lid between upper cover 1 and lower cover 2 closes intensity and guarantee between the two not hard up, the both sides edge of upper cover 1 and lower cover 2 adopts the step cooperation, and the step is close to connector port 4, and is concrete, and 2 both sides lateral walls of lower cover are equipped with two-stage step and form three plane from top to bottom: first face 201, second face 202 and third face 203, be the first connection inclined plane 204 that is concave to connector port 4 between first face 201 and the second face 202, be the second connection inclined plane 205 that is concave to connector port 4 between second face 202 and the third face 203, first boss 21 and second boss 22 hug closely lateral wall 20 and the high post 25 top surface and the height of second face 202 below first face 201 is equal, and after PCB board 3 erects on low post 24 top surface, its upper surface just is with high post 25 top surface, second face 202 flush. The third face 203 is also provided with a positioning strip 206 which protrudes upwards, and the positioning strip 206 in the embodiment leans against the inner side of the side wall of the lower cover. Correspondingly, the side walls of the two sides of the upper cover 1 are also provided with two steps and form an upper plane and a lower plane: a fourth surface 104 and a fifth surface 105, a third connection inclined surface 107 protruding toward the connector port 4 is provided between the fourth surface 104 and the fifth surface 105, and the fourth surface 104 extends above the upper cover to form a fourth connection inclined surface 108. When the upper cover 1 is matched and covered with the lower cover 2, the fourth surface 104 is matched and contacted with the second surface 202, the fifth surface 105 is matched and contacted with the third surface 203, the first connecting inclined surface 204 is matched and contacted with the fourth connecting inclined surface 108, the second connecting inclined surface 205 is matched and contacted with the third connecting inclined surface 107, the side wall corresponding to the fifth surface 105 of the upper cover 1 is thinner than the side wall of the lower cover, and the side wall of the upper cover 1 is just sleeved outside the positioning strip 206; the thickness of the sidewall corresponding to the fourth surface 104 is equivalent to the thickness of the sidewall of the lower cover 2, the sidewall corresponding to the fourth surface 104 is folded toward the inside of the upper cover 1 to form a pressing wall 106 when extending toward the connector port 4, and the sidewall corresponding to the first surface 21 of the lower cover 2 clamps the two pressing walls 106 of the upper cover 1 from both sides. The lower surface 1061 of the pressing wall 106 abuts against the top surface of the high post 25 and the upper surface of the PCB 3, and cooperates with the first boss 21 and the second boss 22 to clamp the PCB 3.
