Abstract
The invention discloses a power signal wall through connecting device avoiding short circuit. The power signal wall through connecting device comprises a circuit board, an insulator and a connecting line, wherein a small hole is formed on the circuit board, the insulator is inserted in the small hole on the circuit board, and the connecting line passes through the insulator and is in welding connection with the circuit board. By the power signal wall through connecting device disclosed by the invention, the board is convenient to install and uninstall, and a hidden hazard that a circuit which is externally connected with the insulator and the shell of the insulator is shorted out is eliminated; simultaneously, influences of thermal expansion contraction on a welding part also can be reduced, and the power signal wall through connecting device is convenient to operate and has good practicability.
Description
Technical field
The present invention relates to a kind of power supply signal jockey through walls, particularly a kind of power supply signal jockey through walls of evading short circuit.
Background technology
In the prior art; Increase along with power supply signal number through walls; The insulator number that uses is more and more; And traditional mode is directly insulator to be welded on the plank, will cause the installation and removal of plank so very big trouble simultaneously during thermocycling because the coefficient of expansion of plank and the different rosin joints that are prone to cause the tie point place of the coefficient of expansion of insulator.
Summary of the invention
The purpose of this invention is to provide a kind of power supply signal jockey through walls of evading short circuit, not only be convenient to the installation and removal of plank; Eliminated the hidden danger of shell short circuit of circuit and the insulator of external communications insulator; Simultaneously, also can reduce when expanding with heat and contract with cold influence to weld; Easy to operate, have good practicability.
In order to realize above purpose, the present invention realizes through following technical scheme:
A kind of power supply signal jockey through walls of evading short circuit comprises:
Circuit board has aperture on the described circuit board;
Insulator, described insulator are plugged in the aperture on the circuit board;
Connecting line, described connecting line pass insulator and are welded to connect with circuit board.
Described insulator is provided with the insulator inner prop and is set in the outside insulator column jacket of insulator inner prop, and described connecting line passes the insulator inner prop and is welded on the circuit board.
The weld of described connecting line and circuit board is not less than 1mm apart from the distance range of the aperture of circuit board.
The present invention compared with prior art has the following advantages:
1, is convenient to the installation and removal of plank;
2, eliminated the hidden danger of shell short circuit of circuit and the insulator of external communications insulator;
3, can reduce when expanding with heat and contract with cold influence to weld;
4, easy to operate, have good practicability.

Embodiment
Below in conjunction with accompanying drawing,, the present invention is done further elaboration through specifying a preferable specific embodiment.
Like Fig. 1 ~ shown in Figure 3, a kind of power supply signal jockey through walls of evading short circuit comprises: circuit board 4, insulator and connecting line 2.Wherein, The insulator column jacket 5 that insulator is provided with insulator inner prop 1 and is set in insulator inner prop 1 outside; Have aperture on the circuit board 4, insulator is plugged in the aperture on the circuit board 4, and connecting line 2 passes insulator inner prop 1 and welds with circuit board 4; Thereby realize being connected of external circuit and circuit board 4, can evade owing to circuit board 4 the expand with heat and contract with cold circuit board 4 that causes and the problem of insulator junction rosin joint.In the present embodiment; Connecting line 2 is a pad 3 with the junction of circuit board 4; Realize being welded to connect of connecting line 2 and circuit board 4 through pad 3, promptly pad 3 is not less than 1mm apart from the distance range of the aperture of circuit board 4, according to the engineering practical experience; Because the distance that the conducting resinl of welding insulation or soldering are overflowed can not surpass 1mm, therefore eliminated the hidden danger of the shell short circuit of external circuit and insulator.
As shown in Figure 3, when adding man-hour, mark following parameter: the diameter of insulator inner prop 1 is d
1, its length is d
3, its lower end length is d
6, the diameter of insulator column jacket 5 is d
2, the diameter of the aperture of opening on the circuit board 4 is d
5, pad 3 is d with the distance of insulator column jacket 5
4In the present embodiment, above-mentioned size is got respectively: d
1=0.5mm, d
2=1.5mm, d
3=12mm, d
4=4.9mm, d
5=1.9mm, d
6=6.4mm.Because d
4=4.9mm>1mm, therefore, the weld that can guarantee connecting line 2 and circuit board 4 is not less than 1mm apart from the distance range of the aperture of circuit board 4.
Therefore; As depicted in figs. 1 and 2; After the installation, external circuit only is to pass insulator and be welded on the circuit board 4 through a connecting line 2 to realize with being communicated with of insulator, therefore only through connecting line 2 being connected or breaking off and just can easily circuit board 4 be carried out installation or removal; Operation is extremely convenient, has very strong practicality.
In sum, a kind of power supply signal jockey through walls of evading short circuit of the present invention not only is convenient to the installation and removal of plank; Eliminated the hidden danger of shell short circuit of circuit and the insulator of external communications insulator; Simultaneously, also can reduce when expanding with heat and contract with cold influence to weld; Easy to operate, have good practicability.
Although content of the present invention has been done detailed introduction through above-mentioned preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple modification of the present invention with to substitute all will be conspicuous.Therefore, protection scope of the present invention should be limited appended claim.
