Specific implementation mode
Said program is described further below in conjunction with specific embodiment.It should be understood that these embodiments are for illustrating
The application and be not limited to limitation scope of the present application.The implementation condition used in embodiment can be done according to the condition of specific producer
Further adjustment, the implementation condition being not specified is usually the condition in routine experiment.
Fig. 1 to Fig. 4 shows a specific embodiment of this power cable connecting terminal of the application comprising metal material
The water conservancy diversion row 1 of matter and the pressure line terminal 2 that integral structure is lined up with water conservancy diversion, it is clear that pressure line terminal 2 is also metal material.
Multiple (being three in figure) screw attachment holes 101 are formed on water conservancy diversion row 1, there are two line ball holes for the setting of pressure line terminal 2
201, axially through one deformation joint 202 of setting, the inner wall of line ball hole 201 is provided with a plurality of axial direction and prolongs the hole wall of line ball hole 201
The pressuring line groove 201a stretched.
Specifically, above-mentioned pressure line terminal 2 includes：The terminal body 2a that 1 direct integrally connected is arranged with water conservancy diversion, with terminal sheet
The direct integrally connecteds of body 2a and the crimping arm 2b of two L-types being arranged symmetrically at left and right sides of the terminal body 2a.Two pressures
Above-mentioned line ball hole 201 is collectively formed in line arm 2b and terminal body 2a, and above-mentioned deformation joint 202 is formed in two crimping arm 2b
Between.
When practical application, power cable 5 is penetrated into line ball hole 201, and by crimp to pressure line terminal 2 (because
The presence of deformation joint 202 so that pressure line terminal 2 is prone to compressive deformation, and 201 aperture of line ball hole reduces after extruding) and by power electric
Cable 5 is pressed abd fixed in line ball hole 201.Specifically, after power cable 5 penetrates line ball hole 201, crimping arm is squeezed by external force
2b, 201 aperture of line ball hole reduce, and power cable 5 is pinched at line ball hole 201 and is connect with the inner wall large area of line ball hole 201
It touches, reduces the contact resistance of power cable 5 and the connecting terminal.Screw attachment holes 101 are used to that the water conservancy diversion to be arranged 1 by screw
It is connected on external equipment (arranging 4 than connection described as follows).
Because the connecting terminal of the present embodiment uses above-mentioned special structure type, so above-mentioned power cable 5 can be by
Stranded conductor is formed in parallel, and non woven web twisted wire mode (not being woven together) is used between conducting wire, per share conducting wire 5A-50A is not
Deng depending on total current needs, per share conductive line surfaces individually coat heat conductive insulating protective layer, and heat dissipation performance improves, and heat is not easy
It concentrates, safety coefficient improves.
And then further improve power cable 5 and connecting terminal in the pressuring line groove 201a of 201 inner wall of line ball hole setting
Contact surface reduces contact resistance, reduces fever, while enhancing the bonding strength (pulling capacity) of power cable 5 and connecting terminal, drops
The possibility that low dynamics cable 5 is detached from from line ball hole 201.
In the present embodiment, water conservancy diversion row 1 is string configuration, and above three screw attachment holes 101 arrange 1 length along water conservancy diversion
Direction uniform intervals arrangement, and pressure line terminal 2 is arranged in the end of water conservancy diversion row 1.
The axially bored line of line ball hole 201 and the axially bored line of screw attachment holes 101 are arranged vertically, and so more convenient water conservancy diversion arranges 1
External and power cable 5 access.
Further, the cross section of above-mentioned water conservancy diversion row 1 is U-shaped structure comprising water conservancy diversion arranges bottom wall 1a and direct one
Body is connected to two water conservancy diversion row side wall 1b at left and right sides of water conservancy diversion row's bottom wall 1a, and water conservancy diversion arranges bottom wall 1a and two water conservancy diversion row's side wall 1b
Between be formed with U-type groove, and above-mentioned screw attachment holes 101 are then vertically installed in water conservancy diversion row's bottom wall 1a upper (rather than water conservancy diversion arrange side
Wall 1b).
And above-mentioned terminal body 2a and water conservancy diversion row's bottom wall 1a arrangements are on the same line.
Two crimping arm 2b corresponding with one of line ball hole 201 is direct with above-mentioned two water conservancy diversion row's side wall 1b respectively
Integrally connected.And the axially bored line of this line ball hole 201 is extended in above-mentioned U-type groove and is extended in the same direction with the length of U-type groove, together
When this line ball hole 201 be also directly connected to U-type groove.So designing is advantageous in that so that penetrates the dynamic of this line ball hole 201
Power cable 5 can extend into the length of bigger, and power cable is allowed not only to be contacted with 201 hole wall of line ball hole, but also with water conservancy diversion row's
Water conservancy diversion arranges bottom wall 1a and water conservancy diversion row's side wall 1b contacts, improves contact area, further decreases contact resistance.
When practical application, the electric current of each conducting wire flows to water conservancy diversion row 1 after the confluence of pressure line terminal 2, and water conservancy diversion row 1 is again by wearing
The screw entered in screw attachment holes 101 is connected (being detachably connected) with the row of connection 4, and connection row 4 connect with bus-bar 3 again, to
Bus-bar 3 is induced current into, realizes the series connection between battery modules.
Depending on overcurrent size and space size, the height of pressure line terminal and the size of width direction can suitably increase and decrease, crimping
The quantity in hole can be increased as needed.
Above-described embodiment is only the technical concepts and features for illustrating the application, and its object is to allow people that can understand this Shen
Content please is simultaneously implemented according to this, and the protection domain of the application can not be limited with this.It is all according to the application main technical schemes
The equivalent transformation or modification that Spirit Essence is done, should all cover within the protection domain of the application.
