However, this type of motor seat has the following problems: First, a hole is opened in the housing, and the conductive terminal is embedded in the housing through the hole.

DETAILED DESCRIPTION

[0020] In this embodiment, refer to Figure 1-Figure 5The integrated motor base includes a shell 1 and a conductive terminal 3. The shell 1 is an integrally formed structure. A terminal hole 11 is provided in the shell 1. The entrance of the terminal hole 11 is provided on the side wall of the shell 1 (the front side wall or the rear side wall), and the front end of the terminal hole 11 is a closed structure; the conductive terminal 3 is installed in the terminal hole 11, and a retaining structure is provided between the conductive terminal 3 and the shell 1. The retaining structure fixes the conductive terminal 3 to prevent the conductive terminal 3 from withdrawing from the terminal hole 11; the conductive terminal 3 has a terminal foot 31, and the terminal foot 31 extends upward through the upper surface of the shell 1, and the main part of the conductive terminal 3 is covered by the upper surface of the shell 1, which plays a role in maintaining the conductive terminal 3 in the upper and lower directions.

[0021] A retaining spring piece 32 is provided at the bottom of the conductive terminal 3 and extends obliquely downward and toward the opening of the terminal hole 11. A card slot 16 is provided at the bottom of the terminal hole 11 inside the shell 1. The retaining spring piece 32 is inserted into the card slot 16 to form a retaining structure for the conductive terminal 3.

[0022] A terminal groove 12 is provided on the upper surface of the housing 1 along the upper portion of the terminal hole 11 . The terminal pins 31 of the conductive terminals 3 pass through the terminal groove 12 and extend above the upper surface of the housing 1 .

[0023] The upper surface of the housing 1 is provided with a socket 13, which extends through the upper surface of the housing 1 and faces the conductive terminal 3 mounted in the terminal hole 11. After the motor is mounted on the motor base, electrical connections are established with the conductive terminal 3 via the terminal pin 31 and the socket 13.

[0024] The terminal holes 11 are arranged obliquely in the housing 1 so that the conductive terminals 3 are installed in the housing 1 in an oblique manner. This can minimize the width of the entire motor base and separate adjacent terminal holes 11 from each other.

[0025] At the bottom of the terminal hole 11, a retaining groove 14 is provided along the longitudinal direction of the terminal hole 11 to prevent the spring clip 32 from passing through. A raised portion 15 with an inclined surface is provided at the end of the retaining groove 14, and a retaining groove 16 is provided behind the raised portion 15. When the conductive terminal 3 is inserted into the terminal 11 through the opening of the terminal hole 11, the conductive spring clip 32 enters along the retaining groove 14, passes over the raised portion 15, and then engages with the retaining groove 16, thereby preventing the conductive terminal 3 from retreating. At the same time, the terminal foot 31 enters along the terminal slot 12 until it reaches the end of the terminal slot 12.

[0026] The top edge of the conductive terminal 3 opposite to the insertion hole 13 is provided with an inwardly and downwardly inclined guide surface 33 , so as to facilitate the insertion of the motor's docking component into the conductive terminal 3 .

[0027] On both sides of the housing 1, there are respectively provided with fixing ears 2 protruding outwards, and on the bottom surface of the fixing ears 2, there are provided positioning columns 21 protruding downwards. The motor base is fixed by means of the positioning columns 21 and screws passing through the fixing ears 2.

[0028] The fixing ear 2 and the housing 1 are an integral structure and are integrally injection molded with a plastic material.

[0029] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
