Description

Technical Field

[0001] The utility model relates to the technical field of automobile circuit equipment, in particular to an input terminal seat of a new energy automobile motor controller. Background Art

[0002] With the development of new energy electric vehicle technology, the integration, power density and intelligence level of motor controllers are constantly improving to meet the requirements of electric vehicles for high efficiency, reliability and intelligence. In order to connect more automotive devices, existing motor controllers are usually equipped with multiple sets of input terminal blocks to connect more device connection lines. The existing input terminal blocks can basically meet daily usage needs, but there are still some shortcomings that need to be improved.

[0003] Most of the widely used input terminal blocks on the market are cast in one piece. The motor controller is connected to various in-vehicle devices by inserting the connector on the external connection line into the interface on the input terminal block. However, in actual use, since the input terminal block and the connector are mostly connected by a simple snap-on connection, once the vehicle passes through bumpy roads many times, it is easy to cause the connection on the input terminal block to loosen, which may cause the line to disconnect accidentally and have poor stability. For this reason, we propose an input terminal block for a new energy vehicle motor controller to solve the above problem. Utility Model Content

[0013] Beneficial effects:

[0014] 1. The utility model installs a movable positioning clamp on the input terminal seat. When the connector needs to be installed, the connector can be inserted into the connection port, and then the positioning clamp is rotated to allow the sliding sleeve to drive the positioning clamp to rotate to just above the connector. Then the locking screw sleeve is rotated to allow the locking screw sleeve to push the sliding sleeve to move downward along the column under the action of the thread. When the positioning clamp moves to the outside of the connector driven by the sliding sleeve, the positioning clamp can form a stable limiting effect on the connector, preventing the connector from accidentally detaching from the connection port on the input terminal seat, thereby effectively improving the stability of the device when in use.

[0015] 2. The utility model installs a positioning column on the side end of the column. When the sliding sleeve needs to drive the positioning clamping plate to rotate above the connecting head, the sliding sleeve can drive the extension rod to rotate to the positioning column, so that the positioning column limits the rotation angle of the sliding sleeve, so that the positioning clamping plate can be quickly rotated to the top of the connecting head without spending much time on positioning, thereby improving the convenience of using the device.

[0022] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, an input terminal seat of a new energy vehicle motor controller includes an input terminal seat 1, a connection port 2 opened on the input terminal seat 1 and a connector 3 movably plugged into the connection port 2, a column 4 is fixed to the middle of the top of the input terminal seat 1, a sliding sleeve 5 is arranged on the outside of the column 4, a positioning clamp 6 is fixed to the left side wall of the sliding sleeve 5, the positioning clamp 6 can cover the outer wall of the top of the connector 3, an external thread 7 is opened on the upper end of the column 4, a locking screw sleeve 8 is threadedly connected to the external thread 7, and a reset spring 13 is arranged on the outside of the lower end of the column 4.

[0023] By installing a movable positioning clamp 6 on the input terminal seat 1, when the connector 3 needs to be installed, the positioning clamp 6 can be rotated first, so that the positioning clamp 6 drives the sliding sleeve 5 to rotate away from the top of the connection port 2, and then the connector 3 can be inserted into the connection port 2, and then the positioning clamp 6 is rotated in the opposite direction, so that the sliding sleeve 5 drives the positioning clamp 6 to rotate to the top of the connector 3, and then the locking screw sleeve 8 is rotated, so that the locking screw sleeve 8 can push the sliding sleeve 5 to move downward along the column 4 under the action of the thread, and the sliding sleeve 5 puts pressure on the reset spring 13 to deform the reset spring 13. When the positioning clamp 6 moves to the outside of the connector 3 driven by the sliding sleeve 5, the positioning clamp 6 can form a stable limiting effect on the connector 3, thereby preventing the connector 3 from accidentally detaching from the connection port 2 on the input terminal seat 1, and effectively improving the stability of the device during use.

[0024] In other embodiments, a positioning column 10 is provided at the right end of the column 4, an extension rod 11 is fixed to the right end side wall of the sliding sleeve 5, and a positioning groove 12 is provided at the end of the extension rod 11;

[0025] By installing a positioning column 10 on the side end of the column 4, when the sliding sleeve 5 needs to drive the positioning clamping plate 6 to rotate above the connecting head 3, the sliding sleeve 5 can drive the extension rod 11 to rotate to the positioning column 10, so that the positioning column 10 limits the rotation angle of the sliding sleeve 5, so that the positioning clamping plate 6 can be quickly rotated to just above the connecting head 3, without spending much time on positioning, thereby improving the convenience of using the device.

[0026] In other embodiments, the inner diameter of the sliding sleeve 5 is the same as the outer diameter of the column 4, and the sliding sleeve 5 is slidably connected to the column 4;

[0027] Through this design, the sliding sleeve 5 can drive the positioning clamping plate 6 to move up and down and rotate smoothly along the column 4, thereby improving the stability of the device during use.

[0028] In other embodiments, a plurality of groups of anti-slip convex strips 9 are fixed at equal intervals on the outside of the locking screw sleeve 8 along the axis of the locking screw sleeve 8;

[0029] This design makes it easier for the user to rotate the locking nut 8 , thus preventing the locking nut 8 from accidentally slipping out of the user's hand.
