Detailed Description

In order to connect a wire harness and a lithium battery together conveniently, and therefore solve the problem that potential safety hazards exist in connection between the existing lithium battery and a circuit in the prior art, the embodiment of the utility model provides a circuit connecting device for the lithium battery. The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the present embodiment provides a line connection device for a lithium battery, including a lithium battery body 1, a connector 2 is fixedly installed above the lithium battery body 1, a wire harness 4 is slidably installed inside the connector 2, an installation groove 21 for installing the wire harness 4 is opened inside the connector 2, a space for inserting the wire harness 4 is left, and a fastening mechanism 3 for fixing the wire harness 4 inside the installation groove 21 is disposed in the middle of an inner cavity of the installation groove 21.

In order to improve the fixing effect of the fastening mechanism 3, the fastening mechanism 3 includes a clamping block 31 and a rotating ring 32, a rotating groove 212 is formed in an inner cavity of the mounting groove 21, a rotating space of the clamping block 31 is reserved, the clamping block 31 is rotatably mounted inside the rotating groove 212 through a rotating shaft, an arc-shaped clamping groove 42 matched with the clamping block 31 is formed in the outer wall of the wire harness 4, and the rotating ring 32 is rotatably connected with the outer wall of the connector 2 through threads and is located below the clamping block 31.

Upwards rotate through swivel becket 32 for fixture block 31 takes place to rotate and arc draw-in groove 42 looks joint, thereby fixes pencil 4 in the inside of mounting groove 21, thereby reaches the purpose that pencil 4 and lithium cell body 1 are connected, and swivel becket 32 just covers swivel becket 212 this moment, makes outside dust can not get into the inside of mounting groove 21, prevents that external dust from causing the phenomenon of short circuit to pencil 4 and lithium cell body 1's junction.

In further embodiment, in order to overhaul pencil 4 and lithium cell body 1 junction for the convenience, reset spring has been cup jointed to the surface of pivot, and when swivel 32 downstream, reset spring drives fixture block 31 and takes place to rotate for fixture block 31 and arc draw-in groove 42 phase separation reach the purpose of being convenient for overhaul pencil 4 and lithium cell body 1 junction.

In order to prevent the rotating ring 32 from rotating to drive the fixture block 31 to move with a large resistance, the horizontal distance from the lowest end of the fixture block 31 to the connector 2 is greater than the ring width of the rotating ring 32 and 3-5cm, the tip of the fixture block 31 is staggered with the upper surface of the rotating ring 32, and the phenomenon that the tip of the fixture block 31 is stuck with the rotating ring 32 due to an excessively large friction force is avoided.

In a further embodiment, one end of the latch 31 away from the wire harness 4 may be provided as a rotating ball, so that the friction between the latch 31 and the rotating ring 32 is changed into rolling friction, thereby further achieving the purpose of preventing the dead locking.

Example 2

Referring to fig. 2, a further improvement is made over example 1: in order to make the pencil 4 sealed effectual with connector 2 junction, 4 surfaces of pencil are provided with the sealing mechanism 5 who plays sealed protection to pencil 4 and connector 2 junction, sealing mechanism 5 includes stopper 51 and

slip ring

52, 4 surfaces of pencil seted up with stopper 51 assorted spacing groove 41, the inner wall and the stopper 51 fixed connection of slip ring 52, the inside of spacing groove 41 is provided with the compression spring 411 that provides elasticity to stopper 51, the roof of mounting groove 21 seted up with slip ring 52 assorted ring channel 211.

Inside back when pencil 4 inserts mounting groove 21, receives the influence of manual driving force, slip ring 52 takes place to slide and the laminating of ring channel 211 back for fastening device 3 accomplishes the fixed to pencil 4, then under compression spring 411's influence, and slip ring 52 laminates with ring channel 211 often, thereby reaches sealed function, and even slip ring 52 receives the influence to take place certain corrosion and erosion after, still can guarantee the laminating effect of slip ring 52 and ring channel 211.
