Description

Technical Field

[0001] The utility model relates to a bus bar detection device, in particular to a detection device for detecting the direction of bus bar terminals. Background Art

[0002] Some bus bars are directly arranged on the integrated bus bar of new energy power batteries for collecting and transmitting signals. After the terminals of the bus bar are installed, it is necessary to detect whether the installation direction is correct. As Figure 1 shown, a bending part 100 is provided in the middle of the terminal 10. For different bus bars, the orientation of the bending part 100 is different. After installation, workers need to detect whether the orientation of the bending part 100 of all terminals 10 is correct.

[0003] Currently, the commonly used detection method is to detect by human eyes. However, human eye detection is not only prone to fatigue and missed detection, but also the surface of the terminal 10 is a smooth surface, resulting in a reflection phenomenon, which is very inconvenient for human eye observation. Content of the Utility Model

[0004] In order to overcome the disadvantages and deficiencies in the prior art, the purpose of the utility model is to design a detection device, which can replace manual labor to detect the installation direction of bus bar terminals and improve the detection efficiency and accuracy.

[0005] To achieve the above purpose, the utility model provides a detection device for detecting the direction of bus bar terminals. The detection device includes: a horizontal bracket, a vertical bracket, a contact mechanism, a signal line and a resistance tester. The vertical bracket is movably arranged on the horizontal bracket in the left-right direction. The contact mechanism is movably arranged on the vertical bracket in the front-back direction. One end of the signal line is electrically connected to the resistance tester. When the contact mechanism contacts the bus bar terminal, the other end of the signal line is electrically connected to the contact mechanism. When the contact mechanism does not contact the bus bar terminal, the other end of the signal line is not electrically connected to the contact mechanism.

[0006] Further, the vertical bracket includes: an upper cover and a base. The upper cover and the base are fixed and form a guiding channel arranged in the front-back direction. The contact mechanism includes: a support and an elastic contact. The elastic contact is arranged on the support. The other end of the signal line is inserted into the elastic contact. When the contact head of the elastic contact contacts the bus bar terminal, the other end of the signal line is electrically connected to the contact head of the elastic contact. The support is movably arranged in the guiding channel in the front-back direction. At least a part of the contact head of the elastic contact is located directly above the guiding channel. Among them, the upper cover is used to define the upper limit position of the support, and the base is used to support the support and define the left and right limit positions of the support, so that the entire guiding channel can guide the movement of the support.

[0007] Further, the detection device further includes: a magnet disposed in the guiding channel; the support is formed of a magnetic material, and the length of the magnet matches the moving range of the support in the front-rear direction. Wherein, the magnet is used to exert an attractive force on the support. When the position adjustment of the contact mechanism is completed, the attractive force of the magnet can keep the contact mechanism stable at this position, avoiding unnecessary deviation.

[0008] Further, the support is provided with a positioning hole and a shoulder, the elastic contact is disposed in the positioning hole, and the magnet and the shoulder are directly opposite in the up-down direction. Wherein, the upper cover is used for the upper limit position of the shoulder, and the base is used for the shoulder and defines the left and right limit positions of the shoulder; the magnet mainly exerts an attractive force on the shoulder.

[0009] Further, the base is provided with a positioning groove at the bottom of the guiding channel; there are two positioning grooves, shoulders and magnets. The two positioning grooves are arranged in parallel and separated from each other in the left-right direction. The two magnets are respectively disposed in the two positioning grooves, and the two shoulders are directly opposite to the two magnets in the up-down direction. Wherein, the positioning groove is used to position the magnet; by using two magnets to attract the two shoulders respectively, the contact mechanism can be more stably placed at the detection position.

[0010] Further, the base is provided with a wire hole on the front surface or the rear surface of the base and communicated with the guiding channel, and the signal wire passes through the wire hole. Wherein, the provision of the wire hole can facilitate wiring, avoiding the signal wire being wound around other positions or being wound around each other among multiple signal wires.

[0011] Further, there are multiple longitudinal brackets, contact mechanisms and signal wires. Each base is provided with two wire holes, which are respectively located on the front surface and the rear surface of the base. Wherein, the provision of multiple contact mechanisms can simultaneously detect multiple terminals of the busbar.

[0012] Further, the base is provided with a screw hole penetrating the base in the up-down direction. The detection device includes: a quick-release screw. The transverse bracket is further provided with a strip-shaped hole arranged in the left-right direction. The quick-release screw passes through the strip-shaped hole and meshes with the screw hole. Wherein, the provision of the quick-release screw, the strip-shaped hole and the screw hole can position the longitudinal bracket after the position of the contact mechanism is adjusted, avoiding unnecessary deviation of the longitudinal bracket.

[0013] Further, there are two strip-shaped holes, which are arranged in parallel and separated from each other in the front-rear direction; each base is provided with two screw holes, and the number of quick-release screws is equal to the sum of the number of screw holes of all bases. Wherein, the provision of two strip-shaped holes can achieve two-point positioning of the longitudinal bracket, making the fixation more stable.

Detailed Embodiments

[0022] The technical solution of the present utility model will be further described below through embodiments:

[0023] The present utility model provides a detection device for detecting the direction of a busbar terminal, in combination with Figures 2 to 3As shown in the figure, the detection device includes: a transverse bracket 1, a plurality of longitudinal brackets 2, a plurality of contact mechanisms 3, a plurality of signal lines 4, a resistance tester 5, and a magnet 6. The longitudinal brackets 2 are movably arranged on the transverse bracket 1 in the left-right direction, the contact mechanisms 3 are movably arranged on the longitudinal brackets 2 in the front-back direction. One end of the signal line 4 is electrically connected to the resistance tester 5. When the contact mechanism 3 contacts the bent portion 100 of the busbar terminal 10, the other end of the signal line 4 is electrically connected to the contact mechanism 3. When the contact mechanism 3 does not contact the busbar terminal, the other end of the signal line 4 is not electrically connected to the contact mechanism 3. At least a part of the contact mechanism 3 is formed of a magnetic material. The magnet 6 is arranged on the longitudinal bracket 2, and the length of the magnet 6 matches the moving range of the contact mechanism 3 in the front-back direction. Herein, the length of the magnet 6 is the dimension in the front-back direction.

[0024] When using the detection device, first, move the longitudinal bracket 2 left and right and the contact mechanism 3 front and back to move the contact mechanism 3 to a position corresponding to the bent portion 100 of the busbar terminal 10. Then, place the busbar on the transverse bracket 1. Finally, use the resistance tester 5 to detect whether the installation direction of the busbar terminal 10 is correct. For example, when the bent portion 100 of the busbar terminal 10 should be uniformly upward, then when the busbar terminal 10 is correctly installed, the contact mechanism 3 will not contact the bent portion 100. And since the resistance of the signal line 4 can be ignored, if the resistance tester 5 detects a resistance value, it means that the contact mechanism 3 contacts the bent portion 100 of the busbar terminal 10, and the installation direction of this busbar terminal 10 is incorrect; on the contrary, when the bent portion 100 of the busbar terminal 10 should be uniformly downward, if the resistance tester 5 does not detect a resistance value, it means that the installation direction of the busbar terminal 10 is incorrect. It is worth mentioning that the magnet 6 will exert an attractive force on the contact mechanism 3, thereby generating a resistance to the front-back movement of the contact mechanism 3.

[0025] In this embodiment, there are multiple longitudinal brackets 2, contact mechanisms 3, and signal lines 4. The numbers of the contact mechanisms 3 and the signal lines 4 are both twice the number of the longitudinal brackets 2, and there are two contact mechanisms 3 on each longitudinal bracket 2.

The elastic contact 32 is disposed on the support 31, and the support 31 is formed of a magnetic material; the other end of the signal line 4 is inserted into the elastic contact 32. When the contact head of the elastic contact 32 contacts the bent portion 100 of the bus bar terminal 10, an electrical connection is formed between the other end of the signal line 4 and the contact head of the elastic contact 32; the support 31 is movably disposed in the guiding channel in the front-rear direction, and at least a part of the contact head of the elastic contact 32 is located directly above the guiding channel. When adjusting the position, the support 31 moves in the guiding channel in the front-rear direction, and the magnet 6 generates a resistance to the movement of the support 31; during detection, if the contact head of the elastic contact 32 contacts the bent portion 100 of the bus bar terminal 10, it will move downward and form an electrical connection with the signal line 4, thereby generating a resistance.
