Description
Technical field
The utility model relates to sensor technical fields, and in particular to a kind of water level sensor of use in washing machine.
Background technique
The coil rack of most of water level sensor of use in washing machine needs in sensor assembling process currently on the market
It plays screw or rivet hot is fixed, use artificial soldering or automatic soldering process in the place to coil both ends and capacitance connection,
The defects of human weld is easy to produce rosin joint, failure welding, automatic welding machine is to positioning requirements height, and welding effect is inconsistent,
Fraction defective is high.
After the backbone winding wire bonding of the water level sensor of this type, need by actual measurement inductance value screened, then again with
Corresponding capacitor carries out matching welding, it is therefore desirable to which twice welding sequence cannot be welded disposably.Due in the prior art, line
The capacitance terminal and winding terminal of ring framework are ipsilateral equidirectional designs, if can be made using wicking technique in second of wicking
Soldered winding terminal wicking again, is easy to appear tin or tining is excessive, cause rosin joint or bad order.
Utility model content
For the problem that process is more in sensor assembling process, low efficiency for the prior art, and repeat wicking, this reality
A kind of water level sensor of high installation effectiveness is provided with novel, specific technical solution is as follows:
A kind of water level sensor, including shell, and the intracorporal magnetic core of shell, the skeleton component are placed in by skeleton component
Including frame body, the circular hole boss for placing magnetic core, one end setting of the frame body are formed in the frame body
There is inserted sheet, which is vertically installed with capacitor welding ends relative to inserted sheet close to one end of inserted sheet, which uses
It being electrically connected in by capacitor and inserted sheet, the frame body is arranged in parallel with winding terminal relative to inserted sheet far from one end of inserted sheet,
The winding terminal is electrically connected by harness and the magnetic core.
Further, two lateral edge winding terminal length directions of the frame body are formed with edge.
Preferably, at least a pair of of positioning waist hole is offered on the edge.
Further, the shell includes the pedestal being connected together and upper cover, which engages the plane area at place with upper cover
The diaphragm for sealing is provided in domain.
Preferably, adjusting nut is installed on the pedestal, which magnetic core is fixed by lower spring.
Preferably, compression is equipped with upper spring between the upper cover and pedestal.
From the above technical scheme, the utility model in skeleton component by being arranged mutually perpendicular winding terminal and electricity
Holding welding ends does not influence scolding tin quality so that wicking is non-interference twice, efficiency and quality is substantially improved, and can be realized
Scolding tin is automated, water level sensor assembly process is reduced, promotes assembly efficiency.

Fig. 2 is the main view of the utility model middle skeleton component；
Fig. 3 is the side sectional view of the utility model middle skeleton component, and shows the installation site of capacitor；
Fig. 4 is the scheme of installation of skeleton component.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail, it is practical new this is described in detail
Before the technical solution of each embodiment of type, related noun and term are explained, in the present specification, title is identical
Or the identical component of label represents similar or identical structure, and is only limitted to the purpose of signal.
As shown in Figure 1, the water level sensor includes shell, and the intracorporal magnetic core 3 of shell is placed in by skeleton component 2.
The shell includes the pedestal 11 being connected together and upper cover 12, which engages in the plane domain at place with upper cover sets
It is equipped with the diaphragm 13 for sealing, the diaphragm and upper cover cooperatively form closed cavity, pressure variation made to be changed into the shape of diaphragm
Become variable, for the variable transferring in sensor.
The magnetic core 3 is limited by skeleton component, in order to achieve the effect that fastening, between magnetic core and pedestal
Lower spring 4 is installed, by the way that adjusting nut 5 is arranged on pedestal, by lower spring compression magnetic core, magnetic core can also be by shell
Bracket 8 further fix.
Also compression is equipped with upper spring 6 between the upper cover 12 and pedestal 11, which plays to lower spring and diaphragm
The compensating action of deformation quantity can make the offset variable of magnetic core more level off to linear performance.
As shown in Figures 2 and 3, the skeleton component 2 includes frame body 21, is formed in the frame body for placing magnetic
The circular hole boss 22 of core, the accommodating cavity in the circular hole boss can be used for across lower spring 4.
One end of the frame body 21 is provided with inserted sheet 23, which is used for plug terminal, with Wiring harness terminal grafting
Match, single injection-molded, the process for eliminating subsequent artefacts' inserted sheet improves efficiency.
Need to install capacitor welding ends 24 and winding terminal 25 in the frame body 21, wherein winding terminal is mounted remotely from slotting
One end of piece, and be electrically connected by harness 26 and magnetic core, which is wound on the excircle of circular hole boss.The condenser welding
One end that end 24 is arranged close to inserted sheet is connect, and is electrically connected with inserted sheet, capacitor welding ends is for welding capacitor 27.
In order to reach the mutually perpendicular mode of wicking twice, the winding terminal 25 is arranged in parallel with inserted sheet 23, the capacitor
Welding ends 24 is vertically arranged with inserted sheet 23, and such winding terminal and capacitor welding ends are arranged with regard to Relative vertical, can be realized separated tin
Shield avoids influencing caused by the same side tin shield.
It in tin shield, needs skeleton component 2 being mounted on wicking tooling, there is a problem of a limit fixation, this is practical
The novel two lateral edge winding terminal length directions in frame body 21 are formed with edge 27, and offer at least a pair on edge and determine
Position waist hole 28.It is fixed by edge insertion wicking tooling, to realize magnetic core and capacitance connection, passes through orthogonal two
The wicking of secondary different directions completes welding, and can also fix the edge using buckle 7 in sensor assembly, referring to Fig. 4.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this
The various changes and improvements that the technical solution of utility model is made should all fall into the guarantor that claims of the utility model determine
It protects in range.
