Description

Technical Field

[0001] This utility model relates to the field of simulator technology, specifically a DC simulator that can be quickly wired. Background Technology

[0002] The DC power supply simulation instrument is mainly used for functional testing and performance evaluation of mobile power supplies. It integrates a programmable power supply module and two independent electronic load modules. A single device can complete most of the functional tests of mobile power supplies.

[0003] Some devices on the market typically house multiple power modules within a single chassis, with a data processor and display screen connected to each module. This allows multiple power modules to be placed together and operate both collaboratively and independently, thus diversifying the structure of DC power simulators and making their use more flexible.

[0004] However, in actual use, when the above-mentioned equipment is used for wiring testing, excessive current may cause electrical leakage between the wiring port and the connecting wire, resulting in safety hazards. In view of this, we propose a DC simulator that can be quickly wired. Utility Model Content

[0005] The purpose of this invention is to provide a DC simulator that can be quickly wired, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a DC simulator with quick wiring capability, comprising a DC simulator body, a power interface fixedly connected to the back of the DC simulator body, a connection port opened on the back of the DC simulator body, a connector being snapped into the connection port, and a protective component being provided on the outer surface of the connector, the protective component comprising:

[0007] The mounting component is fixedly connected to the outer surface of the connector. The mounting component is shaped like a frustum. A protrusion is fixedly connected to the outer surface of the mounting component. The protrusion is shaped like a ring.

[0008] A protective sleeve is fixedly connected to the outer surface of the connection port. The protective sleeve is umbrella-shaped, and a clip is fixedly connected to the inner wall of the protective sleeve. The inner wall of the clip is provided with an inclined surface.

[0009] Preferably, the connection ports are evenly distributed in a linear array on the back of the DC simulator body, and the size of the connection ports is adapted to the size of the connector, so that the connector can be well inserted into the connection port.

[0010] Preferably, the outer surface of the protrusion is provided with a semi-circular groove, and the protrusion is evenly distributed in a curved driving array on the outer surface of the mounting part, which allows the protrusion and the clip to fit together well and make the connection between the connector and the connection port tight.

[0011] Preferably, the clip is located on the inner wall of the protective sleeve near the outer surface, and the size of the clip is adapted to the size of the protective sleeve. This allows the protective sleeve and the mounting piece to cooperate and block the electric arc that occurs between the connector and the connection port.

[0012] Preferably, the inner wall of the mounting component is provided with a limiting component, the limiting component including a mounting groove, the mounting groove being formed in the inner wall of the mounting component, a small spring being fixedly connected to the inner wall of the mounting groove, and a mounting block being fixedly connected to the end of the small spring.

[0013] Preferably, the size of the mounting block is adapted to the size of the mounting groove, the mounting block is arranged in a right-angled trapezoidal shape, and the side of the mounting block is arranged in an arc shape.

[0014] Compared with the prior art, this utility model provides a DC simulator that can be quickly wired, and has the following beneficial effects:

[0015] 1. This DC simulator with quick wiring, to prevent electric sparks from directly contacting the wiring port and connector, has the connector snapped into the connector port. This allows the frustum-shaped mounting piece to snap into the umbrella-shaped protective sleeve, so that the snapping piece fits precisely between the protrusions on the outer surface of the mounting piece. The protrusions are annular in shape and have semi-circular grooves on their outer surfaces. This increases the friction generated when the snapping piece contacts the protrusions, making it easier for the connector to be inserted into the connector port and making the connection tighter. At the same time, when electric sparks occur between the connector and the connector port, the protective sleeve and the mounting piece will intercept the arc between the mounting piece and the protective sleeve, and the arc will dissipate over time.

[0016] 2. This DC simulator with quick wiring, in order to ensure a tighter connection between the connector and the terminal, features a mechanism where, when the connector is inserted into the terminal, the protruding part of the terminal first pushes the mounting block into the mounting groove. After the connector is fully inserted, the spring force pushes the mounting block out of the mounting groove, applying pressure to limit the connector. The end of the mounting block is also arc-shaped, which further ensures a tighter connection between the connector and the terminal. Attached Figure Description

[0024] like Figures 1-6 As shown, this utility model provides a technical solution: a DC simulator that can be quickly wired, including a DC simulator body 1, a power interface 2 fixedly connected to the back of the DC simulator body 1, a connection port 3 opened on the back of the DC simulator body 1, the connection ports 3 are evenly distributed in a linear array on the back of the DC simulator body 1, the size of the connection port 3 is adapted to the size of the connector 4, so that the connector 4 can be well inserted into the connection port 3, the connector 4 is inserted into the connection port 3, and a protective component 5 is provided on the outer surface of the connector 4. The protective component 5 includes a mounting part 501, a protrusion 502, a protective sleeve 504, and a locking part 505.

[0025] In this embodiment of the present invention, the mounting member 501 is fixedly connected to the outer surface of the connector 4. The mounting member 501 is frustum-shaped, and a protrusion 502 is fixedly connected to the outer surface of the mounting member 501. The protrusion 502 is annular, and a semi-circular groove is provided on the outer surface of the protrusion 502. The protrusions 502 are evenly distributed in a curved driving array on the outer surface of the mounting member 501. This allows the protrusions 502 and the locking member 505 to cooperate well and make the connector 4 and the connector 3 tightly connected. The protective sleeve 504 is fixedly connected to the outer surface of the connector 3. The protective sleeve 504 is umbrella-shaped, and a locking member 505 is fixedly connected to the inner wall of the protective sleeve 504. The inner wall of the locking member 505 is inclined, and the locking member 505 is located on the inner wall of the protective sleeve 504 near the outer surface. The size of the locking member 505 is adapted to the size of the protective sleeve 504. This allows the protective sleeve 504 and the mounting member 501 to cooperate and block the electric arc that occurs between the connector 4 and the connector 3.

[0026] Meanwhile, a limiting component 6 is provided on the inner wall of the mounting component 501. The limiting component 6 includes a mounting groove 601, which is opened in the inner wall of the mounting component 501. A small spring 602 is fixedly connected to the inner wall of the mounting groove 601, and a mounting block 603 is fixedly connected to the end of the small spring 602. The size of the mounting block 603 is adapted to the size of the mounting groove 601. The mounting block 603 is set in a right-angled trapezoidal shape, and the side of the mounting block 603 is set in an arc shape. In this way, when the connector 4 is inserted into the connector 3, the protrusion of the connector 3 will first squeeze the mounting block 603 into the mounting groove 601. After the connector 4 is fully inserted into the connector 3, the elastic force of the small spring 602 will push the mounting block 603 out of the mounting groove 601, so that the mounting block 603 applies pressure to limit the connector 4. The end of the mounting block 603 is set in an arc shape, which makes the connection between the connector 4 and the connector 3 tighter.

[0027] In this invention, during use, the connector 4 is inserted into the connector port 3, allowing the frustum-shaped mounting piece 501 to be inserted into the umbrella-shaped protective sleeve 504. This causes the locking piece 505 to fit precisely between the protrusions 502 on the outer surface of the mounting piece 501. The protrusions 502 are annular in shape and have semi-circular grooves on their outer surfaces. This increases the friction between the locking piece 505 and the protrusions 502, ensuring a tight connection between the connector 4 and the connector port 3. Simultaneously, when an electric arc occurs between the connector 4 and the connector port 3, the protective sleeve 504 and the mounting piece 501 will intercept the arc between them, and the arc will dissipate over time.

[0028] Furthermore, when the connector 4 is inserted into the connector 3, the protrusion of the connector 3 will first push the mounting block 603 into the mounting groove 601. After the connector 4 is fully inserted into the connector 3, the elastic force of the small spring 602 will push the mounting block 603 out of the mounting groove 601, so that the mounting block 603 applies pressure to limit the connector 4. The end of the mounting block 603 is arc-shaped, which facilitates the insertion between the connector 4 and the connector 3 and makes the connection between the connector 4 and the connector 3 tighter.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
