[model utility content]
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art and provides a kind of coil and electric expansion valve thereof, effectively improves glue infiltration wire socket in coil potting process and causes the problem of bad connection.
Solve the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of coil, comprise coil main body and draw wire, described coil main body side is provided with wire interconnecting piece, described wire interconnecting piece is provided with interface, be provided with contact pin in described interface, described extraction wire one end is provided with wire socket, described wire socket insert interface and with contact pin grafting, be connected with coil main body will draw wire, described wire socket connects the side of drawing wire and is provided with for stopping that glue enters the baffle plate of wire socket.
Coil of the present utility model, connect the side of drawing wire at wire socket and be provided with baffle plate, when coil embedding, casting glue is poured into by interface usually, the side of drawing wire is connected because rubber block is positioned at wire socket, can shield wires socket and the space of drawing between wire, enter wire socket to prevent casting glue as far as possible and connect the position of drawing wire, thus solve glue and infiltrate the problem that wire socket causes bad connection.
First specific embodiments of the present utility model, described baffle plate is provided with and allows to draw that wire passes through dodges hole, described in dodge hole hole wall with draw wire and fit tightly.Design like this, does not hinder extraction wire to be normally connected with wire socket, makes rubber block more press close to draw wire simultaneously, can better prevent casting glue from infiltrating in wire socket.
Second specific embodiments of the present utility model, described baffle plate is fixed on wire socket.Anti-baffle plate loosens when encapsulating.
3rd specific embodiments of the present utility model, described baffle plate is insulation spacer.Prevent from drawing conducting between wire, improve reliability.
4th specific embodiments of the present utility model, described Weir Plate Thickness is 0.1mm ~ 0.5mm.
The utility model also proposes a kind of electric expansion valve, comprises the coil described in above-mentioned arbitrary technological scheme.
These features of the present utility model and advantage will embodiment below, exposure detailed in accompanying drawing.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is the structural representation of the utility model preferred embodiment coil main body;
Fig. 2 is the structural representation of drawing wire in the utility model preferred embodiment;
Fig. 3 is the structural representation of wire socket in the utility model preferred embodiment;
Fig. 4 is the structural representation of baffle plate in the utility model preferred embodiment;
Fig. 5 is the connection diagram of baffle plate and wire socket in the utility model preferred embodiment.
[embodiment]
The technological scheme of accompanying drawing to the utility model embodiment below in conjunction with the utility model embodiment is explained and illustrated, but following embodiment is only preferred embodiment of the present utility model, and not all.Based on the embodiment in mode of execution, those skilled in the art under the prerequisite not making creative work obtain other embodiments, all belong to protection domain of the present utility model.
With reference to Fig. 1-3, the coil of the utility model preferred embodiment, comprise coil main body 1 and draw wire 2, coil main body 1 side is provided with wire interconnecting piece 11, wire interconnecting piece 11 lower end is provided with interface 111, contact pin 112 is provided with in interface 111, this contact pin 112 is connected with the electromagnetic coil installed around in coil main body 1, draw wire 2 one end and be provided with wire socket 21, common: on wire socket 21, to be arranged with multiple jack 211, different extraction wires 2 inserts in different jacks 211 also fixing, for convenience of assembling, general is all first be connected to by wire socket 21 to draw on wire 2, again wire socket 21 is inserted interface 111 to make jack 211 and contact pin 112 grafting, so just can realize contact pin 112 and the electric connection of drawing wire 2, after extraction wire 2 is connected to wire interconnecting piece 11, pour into casting glue to interface 111, realize sealing.
Owing to usually also reserving a fixed gap between Socket walls and extraction wire; when carrying out embedding; casting glue is easier to be flowed in wire socket from this space, causes part to draw wire and contacts with bad between conductive jack, and then have influence on the normal use of electric expansion valve.
For this reason, the wire socket 21 of the present embodiment is also provided with casting glue can be stoped to enter baffle plate 3 in wire socket 21, composition graphs 4, 5, concrete: baffle plate 3 is positioned at wire socket 21 and connects the side of drawing wire 2, and be fixedly connected with wire socket 21, like this when can prevent embedding, baffle plate 3 produces and loosens, impact effect, better: the baffle plate 3 of the present embodiment dodges hole 31 according to what draw wire 2 vibrational power flow respective amount and position, extraction wire 2 is connected in the jack 211 of wire socket 21 through the hole 31 of dodging of baffle plate 3, dodge hole 31 hole wall and fit tightly extraction wire 2, thus it is inner that casting glue can better be stoped to enter wire socket 21.
The modes such as the baffle plate 3 of the present embodiment can be connected by screw, be welded to connect, bonding connection are fixed on wire socket 21.In other embodiments of the present utility model, baffle plate also can not be fixed on wire socket, such as, be first placed on wire socket by baffle plate, and extraction wire is connected in the jack of wire socket through the hole of dodging of baffle plate, owing to drawing the effect of wire, at least can ensure that baffle plate can not drop; When carrying out embedding, baffle plate is resisted against on wire socket, also can play and stop casting glue to enter effect in wire socket.
The present embodiment baffle plate 3 used is the insulation spacer that 0.1mm ~ 0.5mm is thick, such as plastic spacer, nylon spacer etc., so can prevent from drawing conducting between wire 2 and the short circuit that causes, improve reliability, and easily process.
The present embodiment is mainly used in electric expansion valve, electric expansion valve mainly comprises valve body and coil, valve body is equivalent to the rotor portion of stepper motor, coil is equivalent to the stationary part of stepper motor, by applying pulse drive signal on the winding of coil, the magnet case pole pawl of coil producing regular magnetic field, driving the magnet rotor of valve body parts inside to rotate, thus the uninterrupted at valve port place in regulation valve body, realize the control to cold medium flux in system.Adopt the coil of the present embodiment, the reliability of electric expansion valve work can be improved further.The concrete structure of electric expansion valve and principle thereof have belonged to known in this field, and the present embodiment no longer describes in detail.
The above; be only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto, is familiar with this those skilled in the art and should be understood that the content that the utility model includes but not limited to accompanying drawing and describes in embodiment above.Any amendment not departing from function and structure principle of the present utility model all will comprise within the scope of the appended claims.
