Summary of the invention
The purpose of this utility model provides a kind of security performance height, is convenient to the terminal box of the power brick of wiring.
For achieving the above object, the utility model has adopted following technical scheme: a kind of terminal box of power brick, comprise for the high voltage input terminal that connects the power brick high-tension electricity and the low pressure input that is used for being connected the power brick low tension, described high voltage input terminal all is connected high-voltage output end and low-voltage output by conductive unit is corresponding with the low pressure input, and described each parts all are fixed on the base.
Owing to adopt above technical scheme, high-tension bus-bar and low tension wire is arranged apart, and each terminals all is fixed on the base, circuit is comparatively clear, is convenient to identify terminals, in the time of can avoiding follow-up wiring the misoperation phenomenon takes place, and prevents that effectively the high-tension electricity accident from taking place.
Embodiment
As Fig. 1, a kind of terminal box of power brick, comprise for the high voltage input terminal 10 that connects the power brick high-tension electricity and the low pressure input 20 that is used for being connected the power brick low tension, described high voltage input terminal 10 all is connected high-voltage output end 30 and low-voltage output 40 by conductive unit 60 correspondences with low pressure input 20, and described each parts all are fixed on the base 50.High-tension bus-bar and low tension wire is arranged apart, and each terminals all is fixed on the base 50, circuit is comparatively clear, is convenient to identify terminals, in the time of can avoiding follow-up wiring the misoperation phenomenon takes place, and prevents that effectively the high-tension electricity accident from taking place.
As Fig. 2, described high voltage input terminal 10 comprises one group of first positive and negative binding post 11,12 at least, high-voltage output end 30 correspondences arrange the second positive and negative binding post 31,32, described first positive terminal 11 is continuous with the second corresponding positive terminal 31 on the high-voltage output end 30 by conductive unit 60, and first negative terminal 12 is continuous with the second corresponding negative terminal 32 on the high-voltage output end 30 by conductive unit 60.That is to say that two groups of corresponding identical binding posts of Semi-polarity interconnect, and realize circuit communication.Binding post in the utility model comprises screw rod and nut, line nose 80 commonly used is enclosed within on the screw rod then fixes with nut, only need get final product on the fixing online nose 80 of electric wire during installation, reduces difficulty for wiring work is installed, and increases work efficiency.
Described low pressure input 20 and low-voltage output 40 are inserting slot construction.Holding wire on the vehicle all is to connect low tension, such as the control unit signal of automobile, because mostly holding wire is to adopt plug construction, low pressure input 20 and low-voltage output 40 is all made the inserting slot construction that cooperates with plug, is convenient to follow-up installation and use.
Described high voltage input terminal 10 and high-voltage output end 30 lay respectively at the two ends of base 50, and described low pressure input 20 is positioned at the side of high voltage input terminal 10, and low-voltage output 40 is positioned at the side of high-voltage output end 30.Like this arrangement more neatly compactly, easily identification, and the part that high voltage input terminal 10 is set on the base 50 in the utility model stretches into behind the inside of power brick and fixing, this structure conserve space is fixed an overall structure with terminal box and power brick.
Described conductive unit 60 is copper sheet.
As Fig. 3, described base 50 is provided with housing 51, and described housing 51 is equipped with U-shaped groove 511 in the corresponding first positive and negative binding post 11, the 12 and second positive and negative binding post 21,22 positions, and the opening of this U-shaped groove 51 all is positioned at the two ends of base 50; That is to say that U-shaped groove 51 surrounds binding post in the middle and offer the breach that passes through for lead, because lead arranges that along the length direction of base 50 therefore also length direction layout and the opening direction along base 50 is opposite for same group of U-shaped groove 51, all toward the outer side.U-shaped groove 51 prevents effectively that with lead neat being fixed in the notch in order adjacent wires from coming in contact, and avoids accident to take place.The position of described housing 51 corresponding low pressure inputs 30 and low-voltage output 40 is provided with breach 512, and this breach 512 is reserved the slot position of input 30 and low-voltage output 40.
As shown in Figure 4, described base 50 comprises rectangular base plate 52 and the nut 53 that is fixed on the base plate 52, housing 51 cards are established and are fixed on the base plate 52, described nut 53 is used for the link post, nut 53 is provided with two groups and lay respectively at the two ends of base plate 52 altogether, every group of nut 53 is even number and arranges two at least, as being provided with the two ends that 53, four nuts 53 of four nuts are distributed in base plate 52 among Fig. 4 altogether.The middle part of described base plate 52 lower surfaces is provided with and base plate 52 vertically arranged connecting plates 54, also is provided with connecting plate 54 on the upper surface of housing 51, is used for connecting the through hole 541 of power brick on the described connecting plate 54.
As shown in Figure 5, be covered with cover body 70 on the described high-voltage output end 40, high-voltage output end 40 is positioned at the cavity of cover body 70, the end of described cover body 70 is provided with the recess 71 that passes for lead, described cover body 70 is provided with for the riser 72 that connects connecting plate 54, and this riser 72 is provided with connecting hole 721 in the position of corresponding through hole 541.That is to say that connecting hole 721 is corresponding with through hole 541, be fixed on the power brick behind screw bolt passes connecting hole 721 and the through hole 541, realize the fixing of terminal box.Cover body 70 is enclosed in the lead of high-voltage output end 40 in the housing 51, and people and lead are kept apart, and prevents that the people from touching high-tension electricity, improves security performance.
