Description

Technical Field

[0001] The utility model belongs to the technical field related to battery production, in particular to a quick connector for testing positive and negative electrodes of a battery. Background Art

[0002] Battery positive and negative electrode test equipment is used to detect the positive and negative polarity of batteries and is primarily used in battery manufacturing and repair. During battery manufacturing, ensuring the correct connection of the positive and negative polarity of battery cells is crucial, as it directly affects battery performance and safety. During battery repair, battery positive and negative electrode test equipment can be used to diagnose battery faults, such as battery pack imbalance and single cell failure. During battery testing, connectors are required to connect to the battery electrodes, but this still has the following drawbacks in actual use:

[0003] When the battery positive and negative electrode test equipment is working, it is directly clamped on the bolt head of the battery through the connector, or the bolt head is loosened and then clamped to connect the bolt head on the battery electrode. During the working process, installation and disassembly are not convenient;

[0004] When the battery positive and negative electrode testing equipment is working, the connector is usually directly connected to the electrode structure. However, during the operation, the structure on it is directly connected through the corresponding clamping structure. During the test process, there are many exposed metal parts, and if the operator accidentally touches them, it is easy to cause a safety hazard of electric shock. Utility Model Content

[0005] The purpose of the utility model is to provide a quick connector for testing the positive and negative poles of a battery. By arranging a heat shrinkable insulating sleeve, a protective sleeve, an inner magnetic block and a detection probe, the utility model solves the problem that the installation and disassembly of the connectors of the positive and negative pole testing equipment of the battery are inconvenient, and there are many exposed metal parts during the installation and testing of the connector, which easily creates a safety hazard of electric shock.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a quick connector for testing the positive and negative poles of a battery, comprising a heat shrinkable insulating sleeve, a protective sleeve, an inner magnetic block and a detection probe. The protective sleeve is fixed on the inner wall of the heat shrinkable insulating sleeve, a hexagonal socket is provided through the center of the bottom end of the protective sleeve, the inner magnetic block is sleeved in the protective sleeve, a filling hole is provided in the inner magnetic block along the central axis, a detection probe is sleeved in the lower part of the filling hole, three signal lines are fixed to the top of the detection probe, when working, the outside of the protective sleeve is insulated by the heat shrinkable insulating sleeve, and the bolt head on the battery is movably connected through the hexagonal socket on the protective sleeve. When the bolt head is adsorbed thereon by the inner magnetic block, the detection probe abuts against the bolt head, abutting against a suitable structure.

[0008] Furthermore, an insulating skirt is fixed to the lower part of the peripheral side of the heat shrinkable insulation sleeve, the bottom end of the insulating skirt is flush with the bottom end of the heat shrinkable insulation sleeve, and the heat shrinkable insulation sleeve protects the protective sleeve through the insulating skirt.

[0009] Furthermore, the bottom end of the heat shrinkable insulation sleeve is open, a through hole is provided in the center of the top end of the heat shrinkable insulation sleeve, and handles are symmetrically fixed on the upper part of the circumference of the heat shrinkable insulation sleeve. The heat shrinkable insulation sleeve is open so that the signal line can pass through the through hole during operation.

[0010] Furthermore, the inner magnetic block and the protective cover are attracted to each other, and a bayonet is provided at the center of the bottom end of the inner magnetic block. The inner diameter of the bayonet is larger than the inner diameter of the filling hole. The bayonet and the filling hole are connected to each other, and the inner magnetic block is movably connected to the limiting ring through the bayonet.

[0011] Furthermore, a limiting ring is fixed to the lower part of the peripheral side of the detection probe, and the limiting ring is movably connected in the bayonet. The bottom end surface of the limiting ring is flush with the bottom end surface of the detection probe. The bottom ends of the detection probe and the limiting ring both extend out of the bottom end of the inner magnetic block. When the detection probe is working, the position between it and the inner magnetic block is determined by the limiting ring.

[0012] Furthermore, a filling strip is fixed to the top of the detection probe, the signal lines are all fixed in the filling strip, the filling strip is fixed in the filling hole, and the detection probe is sealed by the filling strip.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem of inconvenient installation and disassembly of the connectors of the battery positive and negative electrode testing equipment by providing a protective cover, an inner magnetic block and a detection probe. When it is necessary to detect the corresponding data of the battery, hold the heat shrinkable insulating cover, align the hexagonal socket at the bottom end of the protective cover with the bolt head on the battery to be detected, and put the bolt head into the hexagonal socket. Under the magnetic action of the inner magnetic block, the bolt head abuts against the bottom end of the detection probe, and the corresponding data of the battery is detected by the detection probe. After the detection, the inner magnetic block can be separated from the bolt head on the battery electrode by pulling the heat shrinkable insulating cover and the handle thereon, thereby completing the detection operation, making the installation and disassembly of the connectors of the battery positive and negative electrode testing equipment more convenient.

[0015] The utility model solves the problem of large exposed metal parts during the installation and testing of the connectors of the positive and negative electrode testing equipment of the battery, which easily causes the safety hazard of electric shock, by arranging a heat shrinkable insulating sleeve and a protective sleeve. The hexagonal socket at the bottom end of the protective sleeve is put onto the bolt head of the battery electrode. At this time, the insulating skirt around the heat shrinkable insulating sleeve covers the outside of the bolt head of the battery electrode, thereby preventing the operator from accidentally touching the exposed part of the battery electrode during work, thereby preventing the safety hazard such as electric shock.

The protective sleeve 2 is fixed on the inner wall of the heat shrinkable insulating sleeve 1. When the heat shrinkable insulating sleeve 1 is working, the protective sleeve 2 is fixed therein when the staff operates and detects, and the surface of the protective sleeve 2 is insulated to prevent the staff from getting an electric shock during work. A hexagonal socket 201 is provided through the center of the bottom end of the protective sleeve 2, and the bolts on the positive and negative poles of the battery are sleeved therein through the hexagonal socket 201. The inner magnetic block 3 is sleeved in the protective sleeve 2, and the magnetic function is provided by the inner magnetic block 3. A filling hole 301 is provided in the inner magnetic block 3 along the central axis, and the detection probe 4 is connected through the filling hole 301. The detection probe 4 is sleeved on the lower part of the filling hole 301, and the corresponding data of the battery is detected by the detection probe 4. Three signal lines 403 are fixed to the top of the detection probe 4, and the signals detected by the detection probe 4 are output through the signal lines 403.

[0027] Specifically, an insulating skirt 103 is fixed to the lower part of the peripheral side of the heat shrinkable insulating sleeve 1, and the bottom end of the insulating skirt 103 is flush with the bottom end of the heat shrinkable insulating sleeve 1. When the heat shrinkable insulating sleeve 1 is working, when the protective sleeve 2 is put onto the battery electrode bolt to be tested through the hexagonal sleeve 201, the outer side of the battery electrode bolt is protected by the insulating skirt 103 to prevent the operator from accidentally touching it.

[0028] Furthermore, the bottom end of the heat shrinkable insulating sleeve 1 is open, and a through hole 101 is provided in the center of the top of the heat shrinkable insulating sleeve 1. A handle 102 is symmetrically fixed to the upper part of the side of the heat shrinkable insulating sleeve 1.

After being grasped by the handle 102, a pulling effect is provided to separate the protective sleeve 2, the inner magnetic block 3 and the electrode bolt after detection.

[0029] The operating process of this embodiment is as follows: when working, first, the hexagonal socket 201 at the bottom end of the protective sleeve 2 is put onto the bolt head of the battery electrode. At this time, the insulating skirt 103 on the side of the heat shrinkable insulating sleeve 1 covers the outer side of the bolt head of the battery electrode to prevent the operator from accidentally touching the exposed part of the battery electrode during work, causing safety hazards such as electric shock.

After the detection probe 4 is adsorbed in the inner magnetic block 3, the fixing glue is injected into the filling hole 301 on the inner magnetic block 3 to form the filling rubber strip 402, so that when working, the detection probe 4 is fixed in the inner magnetic block 3, and the inner magnetic block 3 is placed in the protective cover 2, and one end of the movably connected magnetic probe is facing the hexagonal socket 201. After the inner magnetic block 3 and the protective cover 2 are adsorbed, the heat shrinkable insulating cover 1 is put on the outside of the protective cover 2, and after the bottom end is flush with the bottom end of the protective cover 2, hot air is heated to heat-seal and fasten the heat shrinkable insulating cover 1, the protective cover 2 and the inner magnetic block 3.

[0033] The operating process of this embodiment is as follows: during operation, when it is necessary to detect the corresponding data of the battery, hold the heat shrinkable insulating sleeve 1, align the hexagonal sleeve 201 at the bottom end of the protective sleeve 2 with the bolt head on the battery to be detected, and put the bolt head into the hexagonal sleeve 201.

After the detection, the inner magnetic block 3 can be separated from the bolt head on the battery electrode by pulling the heat shrinkable insulating sleeve 1 and the handle 102 thereon to complete the detection operation.
