Abstract
The utility model discloses a kind of current sensor, current sensor includes the shell, magnetic core and PCB circuit board being molded, and accommodating chamber is provided on shell, and magnetic core and PCB circuit board are located in accommodating chamber, the upper opening low-pressure injection molding sealing of accommodating chamber.Processing method includes that magnetic core is formed one by injection molding with the shell being molded, then PCB circuit board is installed and is screwed, then PCB circuit board is sealed by the form of low-pressure injection molding, finally injected plastics material extra at aperture position on the shell being molded is removed, obtains current sensor.The magnetic core of current sensor is combined together with the shell being molded, after then group loads onto PCB circuit board, then seals circuit board by way of low-pressure injection molding, the method has saved part and packaging technology cost, and waterproofing grade has reached IP67 ranks.
Description
Technical field
The utility model is related to a kind of current sensor more particularly to electric current a kind of easy to process and high waterproofing grade biographies
Sensor.
Background technology
Traditional current sensor mostly uses parts and assembles, and the current sensor assembled using parts
There is moisture attacks, current sensor caused to damage or make moist etc. influences, and current sensor in an assembling process by
It is upper relatively long to be taken in assembling in there is a large amount of installation procedure, therefore study a kind of easy to process and waterproof etc.
The problem of high current sensor of grade is the utility model research.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of current sensors, have easy to process and waterproof etc.
The high feature of grade.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of current sensor, innovative point exist
In：The magnetic core and PCB circuits that the current sensor includes the shell being molded, is arranged in the shell being molded
Plate is provided with the accommodating chamber of inner hollow and upper opening, the magnetic core and the PCB circuit board on the shell being molded
In the accommodating chamber, the PCB circuit board is located above the magnetic core, and connection is provided on the shell being molded
The conducting wire for the shell exterior being molded described in the PCB circuit board and stretching, the upper opening low-pressure injection molding envelope of the accommodating chamber
Mouthful.
Preferably, the injection hole penetrated through with the accommodating chamber, the injection hole are provided on the shell being molded
Positioned at the shell side being molded.
Preferably, the PCB circuit board screw is anchored on the shell being molded.
Preferably, be provided on the shell being molded for the PCB circuit board be inserted into two guide grooves, two
The guide groove is located at the PCB circuit board both sides.
The utility model has the advantage of：The magnetic core of current sensor is combined together with the shell being molded, so
After group loads onto PCB circuit board afterwards, then circuit board is sealed by way of low-pressure injection molding, the method has saved part and packaging technology
Cost, and waterproofing grade has reached IP67 ranks.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the front view of current sensor in a kind of current sensor of the utility model.
Fig. 2 is the vertical view of current sensor in a kind of current sensor of the utility model.
In figure：1- shells, 2- magnetic cores, 3-PCB circuit boards, 4- accommodating chambers, 5- injection holes, 6- guide grooves.
Specific implementation mode
The magnetic that the current sensor of the utility model includes the shell 1 being molded, is arranged in the shell 1 being molded
Core 2 and PCB circuit board 3 are provided with the accommodating chamber 4 of inner hollow and upper opening, magnetic core 2 and PCB electricity on the shell 1 being molded
Road plate 3 is located in accommodating chamber 4, and PCB circuit board 3 is located at 2 top of magnetic core, and connection PCB circuit is provided on the shell 1 being molded
Plate 3 simultaneously stretches out the conducting wire outside the shell 1 being molded, the upper opening low-pressure injection molding sealing of accommodating chamber 4.Current sensor adds
Work method includes that magnetic core 2 is formed one by being molded with the shell 1 being molded, and then installs PCB circuit board 3 and uses spiral shell
Silk is fixed, then seals PCB circuit board 3 by the form of low-pressure injection molding, finally will be on the shell 1 that be molded at aperture position
Extra injected plastics material removal, obtains current sensor.The magnetic core 2 of current sensor is incorporated in the shell 1 being molded
Together, after then group loads onto PCB circuit board 3, then circuit board is sealed by way of low-pressure injection molding, the method saved part and
Packaging technology cost, and waterproofing grade has reached IP67 ranks.
Be provided with the injection hole 5 penetrated through with accommodating chamber 4 on the above-mentioned shell 1 being molded, injection hole 5 be located at injection molding and
At 1 side of shell.In order to realize that the installation of PCB circuit board 3 is fixed, 3 screw of PCB circuit board is anchored at the shell being molded
On 1.For the ease of the quick positioning at the beginning of PCB circuit board 3 when dress, it is provided on the shell 1 being molded and is inserted for PCB circuit board 3
Two guide grooves 6 entered, two guide grooves 6 are located at 3 both sides of PCB circuit board.
Finally, it should be noted that above example being merely intended for describing the technical solutions of the present application, but not for limiting the present application property skill
Art scheme, it will be understood by those of ordinary skill in the art that, those are modified or wait to the technical solution of the utility model
With replacing, without departing from the objective and range of the technical program, should all cover in the right of the utility model.
