Description
Technical field
The design is related to car electrics accessories field, and in particular to a kind of electronic light truck BMS principal and subordinate link bundle assemblies.
Background technology
Current truck harness work condition environment is severe, and most chassis harness are all an exposure to outer, harness branch chalaza processing letter
It is single, close to heat source or the electrical appliance of heat itself is generated, easy tos produce siphonic effect, is drawn water from chalaza entrance by conducting wire
Inside connector and electrical appliance, cause harness short-circuit, electrical appliance is burnt.The core drive of electric truck is battery pack, battery
It contracts for fixed output quotas raw high pressure high current, is outwardly conveyed by conducting wire, so the protection of the harness and battery pack to connecting battery pack seems
It is particularly important.
Invention content
The purpose of the utility model design is to provide a kind of water proof and dust proof loss prevention, the simple electronic light truck BMS of assembly
Principal and subordinate link bundle assembly.
To achieve the goals above, the BMS principal and subordinate link bundle assemblies of the utility model design, it is characterised in that：Including
Waterproof connector, protective cover of socket connector, harness branch point.Four waterproof connectors pass through the first electric wire, the second electricity respectively
Line, the connection of third electric wire, the waterproof connector outside are cased with protective cover of socket connector, the protective cover of socket connector and the first electricity
Line, the second electric wire, third electric wire connection point are cased with dual heat-shrink tube, are cased with outside first electric wire, the second electric wire, third electric wire
Closed type bellows, first electric wire, the second electric wire, third electric wire are connected by harness branch point, the harness branch
Point inner lead chalaza uses high frequency scolding tin.
It is in funnel-form or type shape, through-hole that four protective cover of socket connector, which use EPDM soft rubber materials, shape,
Small one and large one is fixed on small end cap bellows with the band dual heat-shrink tube of glue, and big end covers on outside waterproof connector, and color can basis
Beauty is selected.
Each conducting wire chalaza at described two inside harness branch point is using scolding tin, scolding tin cover chalaza again after high-frequency welding
Copper wire surface, the finally dual heat-shrink tube of cuff glue at each conducting wire chalaza.
A kind of the utility model design electronic light truck BMS principal and subordinate link bundle assemblies, one side U.S. simple in structure
See it is compact, protection electric wire it is injury-free and easy to assembly, improve the service life of electric wire；On the other hand siphonic effect is prevented,
It is effective to prevent moisture inside conducting wire sucking connector.
Description of the drawings
Fig. 1 is the electronic light truck BMS principal and subordinate links bundle assembly structure schematic diagram of the utility model design.
Fig. 2 is the enlarged structure simplified schematic diagram of part 6 in Fig. 1.
Parts title and serial number in figure：
Waterproof connector 1, protective cover of socket connector 2, the first electric wire 3, the second electric wire 4, third electric wire 5, harness branch point 6,
Wire inner core 61, scolding tin 62, wire insulation 63, the dual heat-shrink tube 64 of band glue, the dual heat-shrink tube 7 of band glue, silent bellows 8.
Specific implementation mode
The structure of the utility model design is described below in conjunction with attached drawing.
As shown in Figure 1, electronic light truck BMS principal and subordinate link bundle assemblies, including waterproof connector 1, protective cover of socket connector 2,
Harness branch point 6.Four waterproofs are connected with each other between patching 1 by the first electric wire 3, the second electric wire 4, third electric wire 5
Together, 1 outside of the waterproof connector is cased with protective cover of socket connector 2, the protective cover of socket connector 2 and the first electric wire 3, second
Electric wire 4,5 junction of third electric wire are cased with dual heat-shrink tube 7 respectively, first electric wire 3, the second electric wire 4, outside third electric wire 5
It is cased with closed type bellows 8, first electric wire 3, the second electric wire 4, third electric wire 5 are connected by harness branch point 6.
The waterproof connector 1 is docked with the battery pack termination plug-in unit that electronic light truck is selected, general that aviation waterproof is selected to connect
Plug-in unit, it is more advantageous on performance of connector.The waterproof connector 1 adds in connector tail portion at anti-cement after being inserted into conducting wire
Reason enhances connector waterproof effect.
2 design outline of the protective cover of socket connector covers waterproof connector in funnel-form or type shape, is similar to
Umbrella rain cover function has certain water proof and dust proof loss prevention effect.Small end is first respectively fitted over first when producing product
Electric wire 3, the second electric wire 4, on third electric wire 5, good sheath to be installed, protective cover of socket connector 2 need to be completed block and cover waterproof
Then connector 1 fixes protective cover of socket connector 2 with the dual heat-shrink tube 7 with glue, be conducive to alleviate most directly impact docking
The damage of plug-in unit, and then play a protective role.
The problem of truck harness work condition environment is severe, and connector water inlet causes harness short circuit and electrical appliance to burn is more and more prominent
Go out, siphonic effect is one of the problem of causing connector and electrical appliance to intake.Electrical appliance is close to the heat sources such as engine and exhaust pipe
Place or electrical appliance itself can generate heat, cause electrical appliance inner air to expand with heat and contract with cold, cause siphonic effect, pass through company
It connects water suction at the conducting wire chalaza of connector and enters connector or electrical appliance.Therefore carrying out the waterproof work at conducting wire chalaza has one
Fixed necessity and importance.In Fig. 2, each conducting wire chalaza at described two inside harness branch point 6 is welded using ratio-frequency welding
It connects, then scolding tin 62 at chalaza, scolding tin covers chalaza copper wire surface, finally the dual heat-shrink tube of cuff glue at each conducting wire chalaza
63.Reinforce the waterproof effect at conducting wire chalaza by the design of special chalaza, reaches and siphonic effect is blocked to absorb water from conducting wire
Into the purpose of connector.
