[0038] The following will be described in detail below with reference to the accompanying drawings. Figure 1 - The accompanying drawings illustrate embodiments of the present application. Figure 5 The present application will be described in further detail.

[0039] The embodiments of the present application disclose a PACK signal acquisition wire harness.

[0040] The PACK signal acquisition wire harness, as shown in the accompanying drawings, comprises an integrated end 1, a wire row 2, a fixing clamp 3, a plurality of acquisition ends 4 and a protective sleeve 5. The integrated end 1 is one of the core components, and the main part thereof can be packaged by an aluminum shell or a plastic shell. Figure 1 Figure 2 The wire row 2 is composed of a plurality of acquisition wires arranged in parallel with each other. The acquisition wires are made of a specific type of conductor, and silver-plated copper wire is recommended as the preferred solution. The silver-plated copper wire can ensure good electrical conductivity in a high-temperature environment.

[0041] The acquisition wires are divided into two ends. The first end of each acquisition wire is connected to the integrated end 1, and the second end of each acquisition wire is connected to an acquisition end 4. The acquisition end 4 is used to collect data information of a battery pack, a circuit and the like, and can be various sensors such as a temperature sensor and a voltage sensor. After each acquisition wire collects data information through the acquisition end 4, the data is transmitted to the integrated end 1, and the data is uniformly processed or distributed to other controllers through the integrated end 1.

[0042] The protective sleeve 5 is wrapped outside the wire row 2. All acquisition wires are sleeved in the protective sleeve 5, and the acquisition wires are arranged through the protective sleeve 5, so that the acquisition wires cannot be randomly swung or placed. The protective sleeve 5 uniformly arranges the wire row 2, so as to avoid the acquisition wires from being disordered due to shaking or vibration during driving of a vehicle, and reduce the probability of damage.

[0043] The protective sleeve 5 is wrapped outside the wire row 2. All acquisition wires are sleeved in the protective sleeve 5, and the acquisition wires are arranged through the protective sleeve 5, so that the acquisition wires cannot be randomly swung or placed. The protective sleeve 5 uniformly arranges the wire row 2, so as to avoid the acquisition wires from being disordered due to shaking or vibration during driving of a vehicle, and reduce the probability of damage.

[0044] ​The fixed fixture 3 is connected to the integrated end 1 and provides fixation for the wire harness 2. The fixed fixture 3 can be in the shape of a "冂". The wire harness 2 is fixed on the integrated end 1 through the fixed fixture 3. The connection method between the fixed fixture 3 and the integrated end 1 can be a sliding connection. Sliding grooves are opened on both sides of the integrated end 1, and the fixed fixture 3 is limited by the sliding grooves and can move along the sliding grooves. The fixed fixture 3 can press the wire harness 2 by its own weight or by setting springs in the sliding grooves, etc., so as to prevent the wire harness 2 from detaching from the integrated end 1 when the vehicle is driving and jolting or vibrating, thereby improving the stability of the connection between the integrated end 1 and the wire harness 2.

[0045] Specifically, both ends of the wire harness 2 formed by the acquisition wires are respectively connected to the integrated end 1 and several acquisition ends 4, so that the acquisition ends 4 transmit the acquired data to the integrated end 1 through the acquisition wires. The connection between the integrated end 1 and the wire harness 2 is fixed by the fixed fixture 3, thereby ensuring the stability of the connection and avoiding disconnection due to jolting or vibrating during vehicle driving. Then, the protection sleeve 5 protects several acquisition wires, so as to prevent the acquisition wires from swinging randomly and getting chaotic when being jolted or vibrated, and reducing the probability of damage.

[0046] Furthermore, the fixed fixture 3 is made of a transparent material, and the transparent material can be composed of transparent plastic, so that the fixed fixture 3 will not block the line of sight and enables the user to clearly observe the stable connection between the integrated end 1 and each acquisition wire. Warning lights can be set at the connection points between the integrated end 1 and each acquisition wire. When the connection is detached, the warning lights can light up and can be easily detected through the transparent fixed fixture 3, which is convenient for the user to reinsert the acquisition wires properly.

[0047] Even further, referring to Figure 3 As shown, the fixed fixture 3 and the integrated end 1 are movably connected, and the movable connection can be a hinge connection. The fixed fixture 3 is provided with a hinge bracket and can rotate along the integrated end 1 by using the hinge bracket. By using this rotation method, the fixed fixture 3 can rotate away from the acquisition wires, and at this time, the fixed fixture 3 and the acquisition wires can be错开, so that it is convenient for the user to replace or maintain the connection points between the acquisition wires and the integrated end 1.

[0048] Even more further, several embedding grooves 31 are opened on the side of the fixed fixture 3 in contact with the wire harness 2. The number of the embedding grooves 31 can be more than the number of acquisition wires, so that the acquisition wires can be respectively stuck in the embedding grooves 31, enabling the acquisition wires to be independently separated from each other, avoiding interference between the signals transmitted respectively, improving the stability of data transmission. At the same time, after being spaced apart from each other, the contact between the acquisition wires is also reduced, avoiding damage caused by mutual friction or impact, and improving the use safety.

[0049] In some embodiments, referring to Figure 1As shown, the protective sleeves 5 are arranged at intervals along the extension direction of the wire row 2, so that the protective sleeves 5 fix the collecting wires at regular intervals, thereby preventing the collecting wires from being scattered again due to jitter or vibration when the interval of the collecting wires is too long, and preventing knotting or mutual entanglement. By using multiple protective sleeves 5 to fix at a preset interval once, the collecting wires are arranged in an orderly manner.

[0050] Further, referring to Figure 4 As shown, the protective sleeve 5 includes a number of spaced portions 51. A spaced opening 511 for the collecting wire to pass through is provided in the middle of the spaced portion 51. The spaced portion 51 adopts a "mouth"-shaped spaced frame with the spaced opening 511 in the middle. The collecting wire can pass through the spaced opening 511, and only a single collecting wire passes through a single spaced opening 511, so as to avoid adjacent collecting wires from contacting each other and prevent the collecting wires from rubbing or colliding with each other when the wheel jitters or vibrates, thus causing damage to the collecting wires.

[0051] A first connecting groove 512 is provided on one side of the spaced portion 51, and a first connecting protrusion 513 is provided on the other side. The adjacent spaced portions 51 are inserted into each other by using the first connecting groove 512 and the first connecting protrusion 513, that is, one spaced portion 51 is inserted into the first connecting protrusion 513 of the other spaced portion 51 through the first connecting groove 512, thereby completing the connection between the two. This method enables the adjacent spaced portions 51 to be disassembled arbitrarily, so that when a certain collecting wire extends to a specified collecting point and needs to be separated from other collecting wires, the corresponding spaced portion 51 can be separated from the adjacent spaced portion 51, avoiding affecting the routing of the collecting wires.

[0052] Furthermore, referring to Figure 4 As shown, the protective sleeve 5 further includes a guiding portion 52; a curved guiding opening 521 is provided in the middle of the guiding portion 52. The structure of the guiding portion 52 is similar to that of the spaced portion 51, the difference being that the guiding opening 521 in the middle of the guiding portion 52 is different from the spaced opening 511. The spaced opening 511 provides a straight-line extension routing for the collecting wire, while the guiding opening 521 provides a curved routing, so that the collecting wire can extend along the curved direction of the guiding opening 521. The guiding portion 52 is generally installed on both sides of all the spaced portions 51, which is convenient for guiding the collecting wire through the curved guiding opening 521 when the collecting wire needs to be separated to the collecting point, so that the collecting wire is less likely to be bent or offset, and also avoids the situation that the collecting wire swings randomly without the fixation of the spaced portion 51.

[0053] The guide portion 52 has a second connecting groove 522 on one side and a second connecting protrusion 523 on the other side. The guide portion 52 is inserted into the spacer portion 51 through the second connecting groove 522 or the second connecting protrusion 523. That is, the guide portion 52 can be inserted into the first connecting protrusion 513 of the spacer portion 51 through the second connecting groove 522, or it can be inserted into the first connecting groove 512 of the spacer portion 51 through the second connecting protrusion 523, depending on the required routing direction of the acquisition line.

[0054] The first connecting groove 512 and the second connecting groove 522 can be T-shaped grooves, trapezoidal grooves or triangular grooves, depending on the requirements. The corresponding first connecting protrusion 513 and the second connecting protrusion 523 can be T-shaped protrusions, trapezoidal protrusions or triangular protrusions.

[0055] A closing block can be provided in the first connecting groove 512, and a notch corresponding to the closing block can be provided on the first connecting protrusion 513.

[0056] Specifically, the second connecting groove 522 or the second connecting protrusion 523 of the guide portion 52 can be inserted into the first connecting groove 512 or the second connecting protrusion 523 of the spacer portion 51, so that the guide portion 52 can be detachably installed on the spacer portion 51. Then, through the curved guide opening 521, the acquisition line can bend along the guide opening 521 when it is running, so that the acquisition line can be stably extended to the data acquisition point.

[0057] If the second connecting protrusion 523 encounters the guide port 521, the guide port 521 can be opened in the second connecting protrusion 523, and the acquisition line can pass through the middle of the second connecting protrusion 523.

[0058] Further, refer to Figure 5 As shown, a connecting port 514 is provided on the wall surface of the first connecting groove 512. A triangular crimping block 515 is movably connected in the connecting port 514. The movable connection can be achieved by setting a movable connecting shaft in the connecting port 514 and setting a movable connecting port on the surface of the crimping block 515. The movable connecting port is inserted into the movable connecting shaft, so that the crimping block 515 can rotate along the movable connecting shaft through the movable connecting port.

[0059] The crimping block 515 extends outward from the connecting port 514 to the first connecting groove 512. When the acquisition line extends through the interval port 511, the acquisition line pushes the crimping block 515, causing the crimping block 515 to rotate outward from the first connecting groove 512, thus blocking the crimping block 515 at the first connecting groove 512.

[0060] When an adjacent spacer 51 or an adjacent guide 52 needs to be inserted into the first connecting groove 512, the first connecting protrusion 513 of the adjacent spacer 51 or the second connecting protrusion 523 of the guide 52 is inserted into the first connecting groove 512. The first connecting protrusion 513 or the second connecting protrusion 523 squeezes and pushes the crimping block 515, causing the crimping block 515 to deflect into the spacer opening 511, thereby pressing the acquisition line with the crimping block 515. The acquisition line is fixed in the spacer opening 511, thus preventing the acquisition line from running away.

[0061] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
