It is further improved, clamping protrusion is respectively equipped on the outside of at least two side walls.To facilitate the clamping with lid.
It is further improved, the centre of bottom has upwardly extended intermediate isolating wall, and intermediate isolating wall side is that magnetic keeps relay
The installing zone of device magnetic circuit system, the intermediate isolating wall other side are the installing zone of magnetic latching relay contact system.
The further preferred protrusion is in the installing zone of magnetic latching relay magnetic circuit system.
It is further improved, bottom is additionally provided with multiple horizontal bars parallel with the side of bottom one on the periphery of the protrusion
Item and the multiple and perpendicular lengthways of rod in the side of bottom one, multiple transverse direction ribs and multiple lengthways of rod composition are latticed,
One of transverse direction rib and a lengthways of rod are directly connected to the protrusion and make all lateral ribs and all lengthways of rod
The protrusion can be connected to；Each radial rib intersects with parts transversely rib and part lengthways of rod.By more
A transverse direction rib and multiple lengthways of rod composition are latticed, and a larger plane is divided into compared with facet, base after injection molding is improved
The Forming Quality and structural strength of seat；Lateral rib and lengthways of rod are connected to also when can improve injection molding with the protrusion and dissolve material
Mobile performance, further increase pedestal injection molding after each section cooling velocity uniformity, prevent the deformation of base bottom.
It is preferred that it is described transverse direction rib and the lengthways of rod it is of same size.
Material is dissolved by two radial rib shortenings when the utility model is molded and reaches pedestal corner distance, so that note
Material is dissolved when modeling can arrive rapidly the farther away corner location of motor seat, it is ensured that each section cooling velocity is more after entire pedestal injection molding
Uniformly, prevent part from moderate finite deformation occur during forming and hardening, it is ensured that the consistency of part size after injection molding.
