Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
The connector plate-inserting structure for automotive air intake pressure-temperature sensor that the utility model provides, as shown in Figure 4, inserted sheet 1 both sides are along its length formed with some bulge-structures 4 respectively.This bulge-structure 4 is distribution in dentation, and each bulge-structure stretches out and is positioned at same plane with inserted sheet, its bearing of trend perpendicular to the length direction of inserted sheet, namely the plug Impact direction of bearing of trend and connector and principal oscillation direction vertical.When inserted sheet 1 and the plastic pellet injection moulding of metal form connector, the bulge-structure 4 of dentation embeds in plastics, the strength of joint of inserted sheet and plastics can be increased, effectively prevent from coming off between metal insert and plastic pellet, and the contact trace of the edge of metal insert and plastic pellet becomes tortuous, as shown in Fig. 4 arrow line, the obstruction of detent projection structure can be subject to when making water or air-flow flow in the gap of inserted sheet and plastics like this, and then the sealing property of connector is significantly promoted.
In the present embodiment, as shown in Figure 5, each bulge-structure 4 is trapezium structure and has fillet, the stress of tension and compression both direction can be resisted like this, and trapezoidal bulge-structure is without wedge angle, not easily forms stress and concentrate, on the bulk strength of plastics connector without impact, the sunk part of adjacent protrusion structure effectively can be combined with plastic pellet, ensures that plastics are connected reliably fastening with metal insert.
Preferably, bulge-structure 4 is distributed in inserted sheet 1 both sides along its length symmetrically, and position and the quantity of its distribution can be arranged according to the specifically stressed of connector.Certainly, described bulge-structure can also be divided into some sections and be arranged in tab edge, this detent projection structure is formed with wafer insert body punching press, do not need additionally to increase frock and operation, and bulge-structure is less relative to inserted sheet overall dimensions, therefore required metal material is less, can not take larger space, not affect the layout of inserted sheet and other parts of sensor.
