The present invention relates to electromagnetic actuator device that the electric flow control valve that is used for freezing thermantidote or electromagnetically operated valve etc. are driven.Be specifically related to a kind of electromagnetic actuator device that makes the dewfall minimizing that produces on the moulded parts surface by cold-producing medium.
Electromagnetic actuator device used in the electric flow control valve of freezing thermantidote etc. or the electromagnetically operated valve etc. constitutes the stator coil portion of stepping motor or the drive coil portion of electromagnetically operated valve, it comprises bobbin, be wound on solenoid on this bobbin, with the yoke around solenoid of this solenoid magnetic combination, is connected the terminal of solenoid and is connected the terminal supporter that goes between, the employing moulded resin is with the integrally moulded formation of solenoid, yoke, terminal supporter and terminal.
For example, comprise as the electric flow control valve that this electromagnetic actuator device is housed: have be communicated with valve chamber once mouthful and secondary mouth and on the valve port of these connections, be provided with the valve body of valve seat, have the valve rod that engages the needle-valve that breaks away from the valve seat of this valve body at the front end place, make stator coil that this valve rod stepping motor of the driven for opening and closing of the mobile hand-manipulating of needle valve of going forward side by side vertically, this stepping motor comprise that the solenoid by electromagnetic actuator device constitutes and the rotor portions of being located at the valve rod place.
And, be to use with coil in adopting the electromagnetically operated valve of electromagnetic actuator device in the past as the electromagnetism that makes the guiding valve action.
In this electromagnetic actuator device, when the fluid that becomes the flow control object was cold-producing medium, the cold and hot surface that is delivered to because of cold-producing medium produced dewfall at the outer surface of moulded parts sometimes.When this dewfall is created in portion of terminal, can produce the problems such as insulation property deterioration that make between the terminal.
Especially portion of terminal simultaneously supports the terminal cover cap so form larger volume because of a supported joint, therefore makes portion of terminal become heat bridge (heat bridge) easily, and portion of terminal produces dewfall.When this dewfall produces, promptly can produce the problem of the insulation property deterioration that makes between the terminal on the face that the terminal of portion of terminal exposes.
The objective of the invention is to solve the problem that above-mentioned electromagnetic actuator device in the past exists, a kind of electromagnetic actuator device that make that cold-producing medium produces cold and hot is difficult to be delivered to the structure of portion of terminal that has is provided.
For addressing the above problem, electromagnetic actuator device of the present invention has solenoid, centers on the yoke and the terminal that is connected with above-mentioned solenoid of this solenoid, adopt moulded resin that above-mentioned solenoid, yoke and terminal is integrally moulded and be provided with portion of terminal around terminal, be characterized in, be provided with area and be bearing in supporting rib on the electromagnetic actuator device body, and be formed with the space that surrounds with above-mentioned portion of terminal, above-mentioned expansion section and above-mentioned supporting rib greater than the expansion section of this portion of terminal sectional area of being located at above-mentioned portion of terminal front with 2 limits of this expansion section.
In addition, the space that forms between above-mentioned portion of terminal, above-mentioned expansion section and the above-mentioned supporting rib in above-mentioned electromagnetic actuator device of the present invention is set to the up/down perforation shape.

The structure of the electromagnetic actuator device of the invention process form is described below in conjunction with Fig. 1-Figure 10.Wherein, Fig. 1 is near the sectional arrangement drawing the terminal portion structure portion of the characteristic structure of explanation electromagnetic actuator device of the present invention, Fig. 2 is the vertical view of the external structure of expression electromagnetic actuator device of the present invention, Fig. 3 is its front elevation, Fig. 4 is its upward view, Fig. 5 is its right hand view, Fig. 6 is the sectional arrangement drawing that is provided with joint and terminal cover cap along EOF line among Fig. 4, Fig. 7 is near the local amplification plan view of the structure terminal structure portion of explanation electromagnetic actuator device of the present invention, Fig. 8 is its local upward view that amplifies, and Fig. 9 is the sectional arrangement drawing along KK line among Fig. 1, and Figure 10 is the drawing in side sectional elevation along LMNP line among Fig. 1, in addition, Fig. 1 is the sectional arrangement drawing along Z-Z line among Fig. 7.
As shown in Figure 6, the electromagnetic actuator device 1 of the invention process form is for adopting moulded resin 20 with the integrally moulded formation of electromagnetic actuator device trial assembly part.That is, electromagnetic actuator device 1 of the present invention is to adopt solenoid 10-2 that solenoid 10-1 that moulded resin 20 such as unsaturated polyester resin for example will center on outer yoke 15-1 and interior yoke 16-1 and outer yoke 15-2 and interior yoke 16-2 center in addition stacked and insert the integrally moulded formation of electromagnetic actuator device trial assembly part that maintains terminal supporter 13 in terminal 14.Solenoid 10-1,10-2 are wound on respectively on bobbin 11-1, the 11-2 that is made up of insulating material.The material of terminal supporter 13 adopts for example PBT (polybutylene terephthalate (PBT)).
The bottom surface of electromagnetic actuator device 1 is formed with steady pin 17, the inner then space 18 of form inserting the rotor that valve is installed.
Below by Fig. 1 and Fig. 7-Figure 10 near the terminal structure portion that has characteristics among the present invention structure is described.The terminal structure portion of electromagnetic actuator device of the present invention comprises: by the portion of terminal 21 of moulded resin 20 with the integrally formed and molded supporting terminal 14 of electromagnetic actuator device body, have be located at these portion of terminal 21 end faces, area is greater than the expansion section 22 of the joint bearing-surface 221 of these portion of terminal 21 sectional areas, supporting rib 23 in the outside of this expansion section 22 of electromagnetic actuator device 1 upper support is located at the space 24 between the medial surface of the inside of portion of terminal 21 and expansion section 22 and supporting rib 23.
22 limit, the left and right sides and top have the terminal shell bearing-surface 222 on every side of supporting terminal shell 40 in the expansion section.These terminal shell bearing-surface 222 upper supports have the end of terminal shell 40, and are fixed by ultrasonic bonding etc.
Because it is littler than the area of expansion section 22 that the sectional area of portion of terminal 21 constitutes, the effect of pretending to heat bridge reduces, and the cold and hot transmission capacity that is delivered to the joint bearing-surface 221 of expansion section 22 reduces, and is difficult to dewfall on the joint bearing-surface 221.
In addition, owing to there is space 24, compare with terminal portion structure in the past, when the surface area in whole terminal structure portion increases, the cold and hot ability of emitting improves, owing to circulation of air in the space 24 is taken away cold and hot, the temperature of whole portion of terminal descends few, so be difficult to dewfall.
In addition because the sectional area of portion of terminal 21 is little, when molded the inflow of moulded resin good, can not produce the space on the portion of terminal 21, can prevent the deterioration of the insulation property between the terminal.
Adopt the present invention, can when guaranteeing sufficient joint bearing area, reduce the sectional area of portion of terminal 21, and can when reducing the heat bridge ability, expansion section 22 be bearing on the body, can not sacrifice the intensity of terminal structure portion, and not have cold and hot influence dewfall.
