At this time, the functional block and the sampling wire harness are detachably connected through the connection terminal, so as to complete the output of the electrical signal collected by the functional block through the sampling wire harness. The complex process of traditional collection point bolt pressure connection, fastening and torque calibration process can be reduced. On the other hand, the damaged collection point can be quickly replaced. If the collection point of the CCS form is abnormal, the replacement will be relatively troublesome and the disassembly will be laborious. This scheme can effectively avoid such inconvenience and greatly improve the operability and maintenance of personnel.

[0010] The above technical scheme is implemented, the fixing foot is inserted after being aligned with the clamping groove, the terminal head is pushed down along the slot of the functional block, and is stopped from downward movement by the limit when reaching the bottom of the functional block. At this moment, the terminal head is rotated clockwise by 45 degrees, so that the fixing foot is clamped in the positioning groove, preventing falling off while connecting the functional block with the sampling wire harness.

[0011] As a preferred scheme of the present application, the fixing foot is provided with four, and the four fixing feet are arranged in a circumferential direction of the terminal head.

[0012] The above technical scheme is implemented, so that the terminal head and the functional block are uniformly and stably connected by the four fixing feet.

[0013] As a preferred scheme of the present application, the terminal head is provided with a placing groove at one end of the slot, and a spring is arranged in the placing groove.

[0015] As a preferred scheme of the present application, the top of the terminal head is provided with an arc-shaped guide part, and a through groove is arranged on the top of the terminal head in an axial direction.

[0016] The above technical scheme is implemented, the functional block is shrunk inwardly under the extrusion force around the through hole during the process of passing through the through hole, the extrusion force disappears when the tip of the functional block passes through the aluminum bar, and the tip of the functional block expands to both sides, thereby realizing fixation of the functional block.

[0017] In summary, the present application has at least one of the following beneficial technical effects:

[0018] 1. The functional block is first inserted into the aluminum bar, and then the terminal head is inserted into the functional block, thereby completing installation of the sampling wire harness.

[0026] The following will be combined with the drawings Figures 1-4 The present application will be further described in detail.

[0027] The embodiment of the present application discloses a quick connection device of a sampling wire harness. Referring to Figure 1The quick connecting device of the sampling wire harness 3 comprises an insulating sheet 1 fixed to the battery core group, and a plurality of aluminum bars 2 and sampling wire harnesses 3 are arranged on the insulating sheet 1, each sampling wire harness 3 is correspondingly provided with a functional block 4, the functional block 4 is detachably arranged on the aluminum bar 2, and a wire connector 5 for connecting with the sampling wire harness is clamped at the tail of the functional block 4. That is, the functional block 4 is first inserted into the aluminum bar 2, and then the wire connector 5 is inserted into the functional block 4, so that the installation of the sampling wire harness 3 is completed, at this time, the functional block 4 and the sampling wire harness 3 are detachably connected through the wire connector 5, so as to complete the output of the electric signal collected by the functional block 4 through the sampling wire harness 3. The complex process of traditional bolt crimping of the collection point, fastening and torque calibration process can be reduced, on the other hand, the damaged collection point can be quickly replaced, the CCS type collection point is relatively troublesome and difficult to disassemble if the collection point is abnormal, this scheme can effectively avoid the inconvenience of this form, and greatly improve the operability and maintenance of personnel.

[0028] The bottom of the functional block 4 is provided with a slot for inserting the wire connector 5, the side wall of the wire connector 5 is provided with a fixing foot 51, the side wall of the slot is provided with a clamping groove 41 for inserting the fixing foot 51, and the clamping groove 41 is communicated with a circumferential positioning groove 42 at one end in the slot, so that the wire connector 5 is aligned in the slot, the fixing foot 51 is inserted into the clamping groove 41 after being aligned, the wire connector 5 is pushed down along the slot of the functional block 4, and stops downward when reaching the bottom of the functional block 4, at this moment, the wire connector 5 is rotated clockwise by 45 degrees, so that the fixing foot 51 is clamped in the positioning groove 42, preventing falling while connecting the functional block 4 and the sampling wire harness 3. In order to prevent the wire connector 5 from shaking in the functional block 4 and causing poor contact, a placing groove is arranged at one end of the slot into which the wire connector 5 is inserted, and a spring 6 is arranged in the placing groove, so that the spring 6 at the bottom of the wire connector 5 is contracted under pressure, and when the wire connector 5 stops at the limiting point, the spring 6 rebounds after the external pressure is removed, the wire connector 5 and the functional block 4 are connected and conductive, and the sampling wire harness is quickly installed.

[0029] In order to ensure the stability of the connection, the fixing foot 51 is provided with four fixing feet 51 which are evenly distributed along the circumference of the wire connector 5, so that the wire connector 5 and the functional block 4 are evenly contacted and stressed through the four fixing feet 51, thereby ensuring the stability.

[0030] An arc-shaped guide portion is arranged at the top of the wire connector, and a through groove is arranged axially at the top of the wire connector. Since the head of the functional block 4 is provided with a through hole, the functional block 4 is contracted inwardly under the extrusion force around the through hole during the process of passing through the through hole, and when the tip of the functional block 4 passes through the aluminum bar 2, the extrusion force around disappears, the top end of the functional block 4 expands to both sides, and the fixation of the functional block 4 is realized.

[0031] The implementation principle of the quick connecting device of the sampling wire harness is that the functional block 4 is aligned with the through hole which is processed on the surface of the aluminum bar 2 in advance. Since the head of the functional block 4 is provided with a through slot, the functional block 4 is shrunk inwardly by the extrusion force around the through hole during the process of passing through the through hole. When the tip of the functional block 4 passes through the aluminum bar 2, the extrusion force around the through hole disappears, and the tip of the functional block 4 expands to both sides, thereby realizing the fixation of the functional block 4.

[0032] The four fixing feet 51 are extended and the bottom is provided with a circular hole, and the internal fixing spring 6 is installed. The terminal 5 is pushed downward along the slot of the functional block 4, and stops downward at the bottom of the functional block 4 after being limited. At this moment, the terminal 5 is rotated clockwise by 45 degrees. Since the bottom spring 6 of the terminal 5 is contracted under the pressure, the terminal 5 stops at the limiting point, and the spring 6 rebounds after the external pressure is removed. The terminal 5 and the functional block 4 are connected and conducted, and the quick installation of the sampling wire harness is realized. When the wire harness needs to be disassembled, the terminal 5 is pressed downward, the bottom spring 6 of the terminal 5 is contracted, and the terminal 5 is rotated counterclockwise by 45 degrees at this moment, thereby realizing the quick disassembly of the sampling wire harness.

[0033] The above are the preferred embodiments of the present application, and are not used to limit the protection scope of the present application. Therefore, any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
