Abstract
The utility model disclose a reed switch assembly structure of an oil level sensor. The structure comprises a casing, an outgoing wire, a reed switch seat and a reed switch. The reed switch seat and the reed switch are arranged in the casing. The reed switch seat is a strip-shaped printed board, and a wire penetrating hole and a limit groove fitting with the reed switch body are arranged on the printed board. The reed switch is arranged in the limit groove, and pins at the two ends of the reed switch are welded on the printed board. The outgoing wire penetrates through the wire penetrating hole, and is fixedly connected with the wire penetrating hole, one end of the outgoing wire is welded with the pin at one end of the reed switch, and the other end is led out of the casing. In the utility model, the reed switch is limited on the reed switch seat, and the fixed assembly position reduces artificial influence factors; the pins at the two ends of the reed switch are welded on the reed switch seat, and the outgoing wire penetrates through the printed board and is connected with the pin of the reed switch, so the outgoing wire does not directly exert force on the reed switch, and the damage possibility of the external force on the reed switch is reduced in the assembly process.
Description
Technical field
The utility model relates to a kind of tongue tube assembly structure, particularly a kind of tongue tube assembly structure of general gasoline engines fuel level sensor.
Background technology
Tongue tube is the abbreviation of dry type tongue spring tube, is a kind of passive electronic on-off element that the contact is arranged, and its shell generally is a sealed glass pipe, and two metallic elastic reed electroplaxs are housed in the pipe, and irritating in the glass tube has inert gas.At ordinary times, two reeds of being made by special material in the glass tube separate.When the glass tube, under the effect of magnetic field magnetic line, two reeds in the pipe are magnetized and the contact of attracting each other as magnetisable material, and reed will be pulled together, the circuit communication that node is connect.After outer magnetic force disappeared, two reeds were owing to the elasticity of itself is separated, and circuit has also just disconnected.Dry type tongue spring tube compact conformation, weight are little, can be installed in extremely limited space, and the utmost point is suitable for microminiaturized equipment, and its switching component is hermetically sealed within the inert gas, contact long working life never with external environment.Therefore, as a kind of circuit switche that utilizes field signal to control, tongue tube can be used as sensor and uses.In practice, usually the connection of controlling these two sheet metals with permanent magnet whether, so be otherwise known as " magnetron ".
In the existing technology, the dry-reed fuel level sensor is a kind of fuel level sensor that general gasoline engines mainly adopts.Tongue tube is installed in fuel level sensor; the float of fuel level sensor is embedded with magnet ring; when float drops to certain position with oil level; because the effect of float internal magnetic ring makes the reed adhesive in the tongue tube; thereby connection warning circuit; and send the oil level restricted speed signal, or quit work by the control control petrol engine to the engine ignition device, thereby reach the petrolic purpose of protection.But a big shortcoming of this sensor is exactly the tongue tube damage of breaking easily, makes sensor failure.The assembly structure of tongue tube as shown in Figure 1 in existing a kind of fuel level sensor, tongue tube seat 3 ' be tubular structure, tongue tube 4 is arranged in this tubular structure, extension line 2 directly is connected with tongue tube 4, and the rigging position of the tongue tube of this assembly structure is wayward, can not directly detect under the air-proof condition, artifical influence factor is bigger, and tongue tube damage when assembling easily, external force directly acts on the tongue tube pin on the extension line, also damages tongue tube easily.
Therefore, need the tongue tube assembly structure in a kind of improved fuel level sensor, simple in structure, easy to assembly, the rigging position of tongue tube is fixed, and tongue tube is difficult for by damage in assembling and use.
The utility model content
In view of this, the utility model provides the tongue tube assembly structure in a kind of improved fuel level sensor, and is simple in structure, easy to assembly, and the rigging position of tongue tube is fixed, and tongue tube is difficult for by damage in assembling and use.
The tongue tube assembly structure of fuel level sensor of the present utility model, comprise housing, extension line and be arranged on housing interior tongue tube seat and tongue tube, described tongue tube seat is the strip printed board, described printed board be provided with lead penetrate the hole and with the stopper slot of tongue tube body conformal; Described tongue tube is arranged in the stopper slot, and tongue tube two ends pin is welded in the printed board; Described extension line penetrates from lead that the hole is passed and penetrate the hole with lead fixedlys connected, and an end pin of extension line one end and tongue tube is welded as a whole, and the other end is drawn from housing.
Further, be provided with installation cavity in the described housing, the tongue tube seat is arranged in the installation cavity, fills with the embedding fluid sealant in the installation cavity;
Further, described printed board is the thick epoxy plate printed board of 1.5mm.
The beneficial effects of the utility model: tongue tube is limited on the tongue tube seat, and rigging position is fixed, and artifical influence factor is little; The tongue tube two pins is welded on the tongue tube seat, and extension line passes printed board and be connected with the tongue tube pin, makes extension line directly not stressed to tongue tube, has reduced the possibility of damage tongue tube in assembling process.
