Description
Technical field
The utility model relates to sensor structure technical fields, refer in particular to a kind of electric connection structure of sensor.
Background technique
Sensor is a kind of detection device, can experience measured information, and the information that can will be experienced, by a set pattern
Rule is for conversion into electric signal or the information output of other required forms, to meet transmission, processing, storage, the display, record of information
With control etc. require.And sensor is since targeted object is different, the type being divided into and working principle are also different, mesh
Before, it is to be transferred to circuit board by the electric signal of acquisition to be analyzed and recorded mostly as Intelligent contact formula sensor, knot
Structure is that upper-lower casing is screwed on mostly, and centre is circuit board power supply by battery.Since its structure is simple, most of producers are for life
It is convenient to produce, and the cathode point that will be generally located on circuit board and lower case in upper housing is directly connected to by conducting wire, and battery is put into
Lower case and after screwing upper housing, battery plus-negative plate and circuit board, cathode point are connected and are formed into a loop.Caused by this structure
Problem is, when taking out battery, upper-lower casing can not be kept completely separate due to conducting wire, and conducting wire is easy to pull apart when dismounting, or makes to touch
Point is empty disconnected to lead to poor contact, and it is not accurate or the failures such as be unable to measure to be easy measurement.
Summary of the invention
The purpose of this utility model is that being directed to the existing state of the art, electric conductivity is provided and is stablized, one kind at low cost
The electric connection structure of sensor.
In order to achieve the above objectives, the utility model adopts the following technical solution:
The utility model is a kind of electric connection structure of sensor, mainly includes upper housing, lower case, the upper housing
In there is circuit board, the circuit board is equipped with resilient contact, and lower case opening is installed with Circular Plate, the Circular Plate and position
Cathode point in lower case bottom is electrically connected, and positive pole is equipped in circuit board, battery is placed in lower case and upper and lower ends point
It is not formed into a loop with positive pole, cathode point contact.
In above scheme, Circular Plate is pcb board, is conducting surface above Circular Plate and contacts with resilient contact.
Further, Circular Plate is connect by the conducting wire being set in lower case shell wall with cathode point.
Further, insulated ring is equipped between lower case and cathode point.
Further, upper housing and lower case are screwed on using screw thread.
The utility model has the following beneficial effects: the utility model is constituted surely by adding resilient contact and PCB electric connection board
Fixed electric connection structure, at low cost, electric conductivity is stablized, and detection is accurate, and convenient for disassembly and assembly and failure rate is low, can effectively avoid biography
System structure is easy to produce that wire fracture, contact void are disconnected to lead to poor contact.
Detailed description of the invention:
Attached drawing 1 is the structural schematic diagram of the utility model.
Specific embodiment:
In order to enable auditor to be further understood that the purpose, feature and function of the utility model, hereby lift preferably real
It applies example and cooperates schema detailed description are as follows:
Refering to Figure 1, being the structural schematic diagram of the preferred embodiment for the utility model, the utility model is one kind
The electric connection structure of sensor mainly includes upper housing 1, lower case 2, has circuit board 3, upper housing 1 in the upper housing 1
It is screwed on lower case 2 using screw thread.The circuit board 3 is equipped with resilient contact 31, and 2 opening of lower case is installed with Circular Plate 4,
The Circular Plate 4 is electrically connected with the cathode point 5 for being located at 2 bottom of lower case, positive pole 6 is equipped in circuit board 3, battery is placed in down
In shell 2 and upper and lower ends contact forming circuit with positive pole 6, cathode point 5 respectively, pass through resilient contact 31 and Circular Plate 4
Connection type constitutes stable electric connection structure, and contact is stablized, convenient for disassembly and assembly.
Specifically, Circular Plate 4 is pcb board, it is conducting surface above Circular Plate 4 and is contacted with resilient contact 31, is i.e. conducting surface
It is electrically connected by the positive pole 6 of resilient contact 31 and circuit board 3, and Circular Plate 4 is by being set to leading in 2 shell wall of lower case
Line is connect with cathode point 5, is put into lower case 2 in battery in this way, and upper-lower casing 1,2 is mutually screwed, then two above and below battery
Pole is electrically connected with positive pole 6, cathode point 5 respectively, forms loop.
Insulated ring 8 is equipped between lower case 2 and cathode point 5,8 preferred rubber circle of insulated ring can avoid cathode point 5 and lower casing
The mutual conduction of body 2 causes short circuit.
Certainly, illustrated above is only the preferred embodiment of the utility model, and the use of the utility model is not limited with this
Range, therefore, it is all made in the utility model principle it is equivalent change should be included in the protection scope of the utility model.
