Description

Technical Field

[0001] This utility model relates to the field of multimeters, and more specifically, to a multimeter with a rotatable probe interface. Background Technology

[0002] Multimeters, also known as multi-purpose meters, are indispensable measuring instruments in the power electronics and other related industries. Their primary purpose is to measure voltage, current, and resistance. Multimeters are classified into analog multimeters and digital multimeters based on their display method. They are multifunctional, multi-range measuring instruments. Generally, multimeters can measure DC current, DC voltage, AC current, AC voltage, resistance, and audio levels. Some can also measure AC current, capacitance, inductance, and certain semiconductor parameters (such as beta).

[0003] A multimeter requires connecting test leads. However, once the test lead wires are connected to the multimeter, the connector cannot rotate. During use, the connecting wires between the test leads and the connector are prone to twisting, generating torsional stress and causing the wire harness to become tangled. Over time, this can easily lead to excessive stress on the connecting wires, causing them to break and resulting in severe wear and tear. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a multimeter with a rotatable probe interface.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A multimeter with a rotatable probe interface includes a multimeter body, a housing fixedly mounted on the outside of the multimeter body, two connecting sleeves rotatably connected to the front of the housing, a mating hole on the multimeter body, a brush block fixedly connected to the back of the connecting sleeve, the brush block rotatably connected to the inside of the mating hole, a connector inserted into the inside of the connecting sleeve, and a test probe connected to the other end of the connector via a wire.

[0007] As a further description of the above technical solution: a limiting ring is fixedly connected to the outer side of the connecting sleeve, and one side of the limiting ring is in rotatable contact with the inner wall of the housing.

[0008] As a further description of the above technical solution: an arc-shaped spring is fixedly installed on the inner side of the connecting sleeve port, and a sliding block is fixedly connected to the other end of the arc-shaped spring. The outer side of the sliding block is slidably connected to the inside of the connecting sleeve. A spring is fixedly connected to one side of the sliding block, and the other end of the spring is fixedly connected to the inside of the connecting sleeve.

[0009] As a further description of the above technical solution: two slots are provided on the outer side of the connector, and the arc-shaped spring piece fits into the slots.

[0010] As a further description of the above technical solution: the front of the housing is provided with a display table and operation buttons for display.

[0011] As a further description of the above technical solution: both sides of the housing are fixedly connected with buckles for holding the test pen.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] This solution achieves automatic rotation by setting a connecting sleeve to engage with the mating hole, and uses an arc-shaped spring piece in conjunction with a sliding block and a spring to achieve stable locking of the connector. This enables the device to achieve free rotation at the connection section while maintaining a stable connection, releasing the stress caused by the torsion of the conductor angle and protecting the conductor.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0021] Please see Figures 1-4 In this utility model, a multimeter with a rotatable probe interface includes a multimeter body 1, a housing 2 fixedly installed on the outside of the multimeter body 1, two connecting sleeves 3 rotatably connected to the front of the housing 2, a docking hole 4 provided on the multimeter body 1, a brush block 5 fixedly connected to the back of the connecting sleeve 3, the brush block 5 rotatably connected to the inside of the docking hole 4, a connector 6 inserted into the inside of the connecting sleeve 3, and a test probe 7 connected to the other end of the connector 6 via a wire.

[0022] In this invention, the outer shell 2 of the multimeter body 1 protects the inner body of the multimeter. The connecting sleeve 3 is rotatably connected to the docking hole 4, allowing the connecting sleeve 3 to rotate freely while maintaining its connection with the multimeter body 1. Then, the connector 6 of the test probe 7 is inserted into the connecting sleeve 3, at which point the connector 6 and the connecting sleeve 3 are stably connected. When the wire between the connector 6 and the test probe 7 undergoes angular torsion and is stretched, the torsional force is transferred to the connector 6, which drives the connecting sleeve 3 to rotate synchronously, thereby releasing the torsional force and ensuring stable connection and normal operation of the device. This invention achieves the advantages of free rotation at the connection section while maintaining a stable connection, releasing the stress generated by the angular torsion of the wire, and protecting the wire. It solves the problems of existing multimeters requiring the connection of test probes, where the connector cannot rotate after the test probes are connected to the multimeter, and the connecting wires between the test probes and the connector are prone to twisting and generating torsional stress during use, causing the wire harness to become entangled. Over time, this can easily lead to excessive stress and breakage of the connecting wires, resulting in severe wear.

[0023] Please see Figure 3 Among them, a limiting ring 11 is fixedly connected to the outer side of the connecting sleeve 3, and one side of the limiting ring 11 is in rotatable contact with the inner wall of the housing 2.

[0024] In this invention, the limiting ring 11 enables the connecting sleeve 3 to rotate while maintaining a limited position, thus ensuring a stable connection between it and the docking hole 4.

[0025] Please see Figure 4 The inner side of the connecting sleeve 3 is fixedly installed with an arc-shaped spring piece 31, and the other end of the arc-shaped spring piece 31 is fixedly connected with a sliding block 32. The outer side of the sliding block 32 is slidably connected to the inside of the connecting sleeve 3. A spring 33 is fixedly connected to one side of the sliding block 32, and the other end of the spring 33 is fixedly connected to the inside of the connecting sleeve 3.

[0026] In this invention, when the connector 6 is inserted, the arc-shaped spring piece 31 is squeezed and unfolds to push the sliding block 32 to compress the spring 33. When the connector 6 is fully inserted, the spring 33 pushes the sliding block 32 to reset, so that the arc-shaped spring piece 31 is reset and locked into the interior of the connector 6, making the connection between the connector 6 and the connecting sleeve 3 stable and achieving synchronous rotation under force.

[0027] Please see Figure 4 The connector 6 has two slots 61 on its outer side, and the arc-shaped spring piece 31 fits into the slots 61.

[0028] In this invention, the slot 61 allows the arc-shaped spring piece 31 to engage and limit the connector 6, thus maintaining a stable connection.

[0029] Please see Figure 1 The front of the housing 2 is provided with a display table 8 and operation buttons 9 for display.

[0030] In this invention, the display table 8 and operation buttons 9 facilitate the observation of test data and control of the multimeter body 1.

[0031] Please see Figure 1 The housing 2 has clips 10 fixedly connected to both sides for holding the test pen 7.

[0032] In this invention, the test pen 7 is positioned and stabilized by the buckle 10, making it easy to store.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
