Problems solved by technology
In this way, the overall structure and assembly process of the junction box are complicated
Therefore, the volume of the junction box is increased
In addition, manufacturing costs increase due to the increased cost of producing, assembling insulating panels and metal busbar layers
[0010] Since the MF connection terminal 117 is mechanically inserted into one surface of the printed circuit board 119, there is a problem in the above-mentioned single-board type junction box, that is, when the relay 113, 114 or the fuse 111, 112 is inserted or pulled out MF connection terminal 117, or the external impact received in the use process after this board 119 is installed on the vehicle, can make connection terminal 117 break off or cause the instability of electric connection
[0011] In addition, it is impossible to solder the connection terminal to the printed circuit board at one time using the wave soldering method (soldering by the fluctuation of the liquid solder contained in the solder liquid container).

Embodiment Construction
[0028] The present invention will be described in more detail below with reference to preferred embodiments shown in the accompanying drawings.
[0029] figure 1 is an exploded perspective view of the junction box in one embodiment of the present invention. Such as figure 1 As shown, the junction box in the embodiment of the present invention includes a top cover 10, which is formed with mounting holes for installing devices such as fuses 11, 12 and relays 13, 14; , 22 and 23 of the printed circuit board 20; and a bottom cover 30 for supporting the printed circuit board 20 with input and output connectors 31, 32.
[0030] Since the top cover 10 and the bottom cover 30 are the same as those in a conventional junction box, no further description will be given here.
[0031] The structure of junction box among the present invention is simple, saves Figure 6 The simple structure of the metal bus bar layer 115 and insulating plate 116 required in the conventional structure sh...

The invention discloses a single board type connection box for mounting on vehicle, the connection box comprises a housing having a top cover and a bottom cover, and a circuit board, the two surfaces of which are provided with connection ends and through-holes for accommodating these connection ends, each of the connection end arranged on one surface of the printed circuit board has a projecting arrangement.
Description
technical field [0001] The present invention relates to an electronic circuit mounted on a vehicle, and more particularly, the present invention relates to a junction box mounted on a vehicle. Background technique [0002] Typically, there are 20 to 30 fuses and about 10 relays on a vehicle. In order to reasonably distribute the electric power in the vehicle according to different modes, junction boxes for protecting the vehicle cables are respectively installed in the vehicle cab and the engine room. [0003] Typically, such junction boxes include a plurality of printed circuit boards (PBCs) arranged in parallel in a vertical direction. In order to realize the electrical connection of the upper and lower printed circuit boards, connecting pins are inserted into the printed circuit boards along the edges of the printed circuit boards, where soldering can be performed. The upper and lower PCBs can be connected by soldering the connection pins on the upper and lower PCBs tog...
