BACKGROUND
1. Technical Field
The present disclosure relates to a motor driver and a connection apparatus of the motor driver.
2. Description of Related Art
In the field of industrial controls, a plurality of motors together used in a system is common. As a result, there must be a plurality of motor drivers to control the motors. However, connecting wires among the plurality of motor drivers for them to use a common power supply is not an easy task.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is an exploded, isometric partial view of an exemplary embodiment of a circuit board of a motor driver, including a connection apparatus.
FIG. 2 is an assembled view of the connection apparatus and circuit board of FIG. 1.
FIG. 3 is an isometric view of three motor drivers each using the connection apparatus of FIG. 1.
DETAILED DESCRIPTION
Referring to FIG. 1, an exemplary embodiment of a motor driver 5 includes a circuit board 10 and a connection apparatus 20. The connection apparatus 20 includes a first connection component 200 and a second connection component 300. In one embodiment, the first connection component 200 and the second connection component 300 have the same configuration. It can be understood that the motor driver 5 further includes other components, such as a controller, however they are not shown in FIG. 1.
Each of the first and second connection components 200 and 300 includes a base 210, two sidewalls 230 perpendicularly extending from opposite sides of the base 210, and two pairs of pins 232 extending from a corresponding end of each sidewall 230. The base 210 defines a slot 211, and two connection portions 212 and 222 located at opposite sides of the slot 211. In the embodiment, the connection portions 212 and 222 are screw holes.
The circuit board 10 includes a first group of vias 11 electrically connected to a positive pole of the circuit board 10, and a second group of vias 12 electrically connected to a negative pole of the circuit board 10. Each group of the first and second groups of vias 11 and 12 includes two pairs of vias. The first group of vias 11 is configured to mount the first connection portion 200. The second group of vias 12 is configured to mount the second connection portion 300.
Referring to FIG. 2, in assembly, the pins 232 of the first connection component 200 are inserted into the first group of vias 11 of the circuit board 10, and the pins 232 of the second connection component 300 are inserted into the second group of vias 12 of the circuit board 10. As a result, the first connection component 200 is electronically coupled to the positive pole of the circuit board 10, and the second connection component 300 is electronically coupled to the negative pole of the circuit board 10. In other embodiments, the pins 232 of the first and second connection components 200, 300 can be welded together with the circuit board 10.
Referring to FIG. 3, three motor drivers 40, 50, and 60 with different specifications share a power supply 70. Each motor driver 40, 50, 60 includes a connection apparatus 20. In use, a positive pole of the power supply 70 is electronically coupled to the connection portion 212 of the first connection component 200 of the motor driver 40, and a negative pole of the power supply 70 is electronically coupled to the connection portion 212 of the second connection component 300 of the motor driver 40. The connection portion 222 of the first connection component 200 of the motor driver 40 is electronically coupled to the connection portion 212 of the first connection component 200 of the motor driver 50, and the connection portion 222 of the second connection component 300 of the motor driver 40 is electronically coupled to the connection portion 212 of the second connection component 300 of the motor driver 50. The connection portion 222 of the first connection component 200 of the motor driver 50 is electronically coupled to the connection portion 212 of the first connection component 200 of the motor driver 60, and the connection portion 222 of the second connection component 300 of the motor driver 50 is electronically coupled to the connection portion 212 of the second connection component 300 of the motor driver 60. As a result, the motor drivers 40, 50, and 60 can conveniently share the power supply 70. It can be understood that one motor driver is electronically coupled to another motor driver via wires 80, the motor driver 40 is electronically coupled to the power supply 70 via the wires 80, and the wires 80 are connected to the connection portions 212 and 222 via screws 90.
The foregoing description of the exemplary embodiments of the disclosure has been presented only for the purposes of illustration and description and is not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. Many modifications and variations are possible in light of the above everything. The embodiments were chosen and described in order to explain the principles of the disclosure and their practical application so as to enable others of ordinary skill in the art to utilize the disclosure and various embodiments and with various modifications as are suited to the particular use contemplated. Alternative embodiments will become apparent to those of ordinary skills in the art to which the present disclosure pertains without departing from its spirit and scope. Accordingly, the scope of the present disclosure is defined by the appended claims rather than the foregoing description and the exemplary embodiments described therein.
