The upper surface of the abutting portion 112 is provided with a mounting hole 119 at the front and the rear of the upper protruding portion 113, and referring to fig. 7, the mounting hole 119 penetrates downward through the lower surface of the base portion 111 for fixing the screw 18.

As shown in fig. 7, the lower protrusion 114 forms a step with the base 111, and the lower protrusion 114 and the upper protrusion 113 are opposite to each other up and down. When the first connector 1 is mounted to the motor main body 400, the lower protrusion 114 extends into the motor main body 400. The waterproof sheet 17 has a central hole 171 so as to be fitted over the outer periphery of the lower protruding portion 114 and attached under the insulating base 11, thereby achieving a waterproof seal between the first connector 1 and the motor main body 400.

Referring to fig. 6 and 7 together, the dielectric base 11 defines a plurality of first power compartments 116, a first signal compartment 117, and a first ground compartment 118. The plurality of first power compartments 116 extend downward from the upper surface of the upper protrusion 113 and beyond the lower protrusion 114, the plurality of first power compartments 116 being arranged along the long side of the upper protrusion 113 that is on the front side. The first signal compartment 117 and the first ground compartment 118 are arranged along the long side of the upper protrusion 113 on the rear side.

Referring to fig. 1, 2 and 5, the first power terminals 12 are fixedly mounted on the insulating base 11. The upper ends of the first power terminals 12 protrude into the plurality of first power compartments 116 in a one-to-one correspondence for electrical connection with the second connector 2. The tail end of each first power terminal 12 protrudes downward beyond the insulating base 11 and rearward for electrical connection with the motor main body 400.

The first signal terminals 13 and the first brake terminals 14 are fixedly mounted on the insulating base 11. The upper ends of the first signal terminals 13 and the first brake terminals 14 extend into the first signal compartment 117 for electrical connection with the second connector 2; the first signal terminals 13 and the first brake terminals 14 are arranged at intervals along the length direction of the first signal compartment 117. The lower ends of the first signal terminals 13 and the first brake terminals 14 also project downward beyond the insulating base 11 and rearward for electrical connection with the motor main body 400.

In this embodiment, the number of the first power compartments 116 is four, the number of the first power terminals 12 is three, and the outermost first power compartment 116 does not accommodate the first power terminal 12 but is used for grounding. The number of the first signal terminals 13 is two, and the number of the first brake terminals 14 is two.

Referring to fig. 6 and 7, the locking plate 15 is made of metal and is preferably fixed to the insulating base 11 by an insert molding process to form an integral structure, so as to enhance the structural strength of the insulating base 11. The locking plate 15 includes a body 151, four hooks 153 bent upward from the body 151, and two first ground terminals 156.

The body 151 is shaped like a flat plate, and has a substantially rectangular opening 1511 in the middle. The body 151 is fixed to the base 111 of the insulating base 11, and the opening 1511 is for the lower protrusion 114 to pass through. The body 151 of the locking plate 15 is also provided with a through hole 1514 aligned with the mounting hole 119 for the screw 18 to pass through and to be securely locked to the motor main body 400. A lug 1512 protrudes outwards from the periphery of the body 151, the lug 1512 extends towards the side surface of the base 111, the end surface of the lug 1512 is substantially flush with the side surface of the base 111, and the lug 1512 can improve the bonding strength between the locking plate 15 and the insulating base 11.

The two first ground terminals 156 are bent upward from the sidewall of the opening 1511 of the body 151, wherein one first ground terminal 156 with a larger width extends into the first ground compartment 118 of the insulating base 11, and the other first ground terminal 156 with a narrower width extends into a corresponding first power compartment 116 of the insulating base 11. The first ground terminal 156 is formed by bending the locking plate 15, and the locking plate 15 and the insulating base 11 form an integral structure, so that the strength is high, and the number of terminals can be reduced, thereby facilitating assembly.

The hooks 153 are bent upward from the left and right sides of the main body 151, and each side of the main body 151 is bent to form two hooks 153 spaced front and back. Each hook 153 has a slot 154 formed therein and extending in the front-rear direction with its opening facing forward. In this embodiment, the hook 153 is substantially in the shape of an "i", and the notch on the left side of the "i" shape corresponds to the slot 154.

As shown in fig. 5, the hook 153 and the side surface of the abutting portion 112 of the insulating base 11 have a space therebetween, and the space is used for the second connector 2 to be mounted. The four hooks 153 are combined to form a locking mechanism 150 for cooperating and locking with the second connector 2. It should be noted that the number of the hooks 153 in the embodiment is four, but the number of the hooks 153 in some embodiments not shown can be reduced to two (i.e. one hook 153 is disposed on each side of the main body 151).

The four second signal compartments 212 and the second ground compartment 213 are arranged along the length of the terminal block 21 and are disposed immediately behind the four second power compartments 211.

Referring to fig. 10 to 12, the number of the second power terminals 22 is four, and the second power terminals are correspondingly disposed in the four second power compartments 211, wherein one second power terminal 22 is used for connecting to the ground wire of the power supply. The number of the second signal terminals 23 and the second brake terminals 24 is two, and the two second signal terminals and the two second brake terminals are correspondingly disposed in the four second signal compartments 212. The front end of the second ground terminal 25 is mounted in the second ground compartment 213, and the rear end of the second ground terminal 25 extends rearward.

Referring to fig. 10, the cover 26 includes a main body 261 and a wire passing portion 262 extending rearward from a rear side of the main body 261. The main body 261 has a rectangular structure with an opening at the lower end and a hollow interior having a receiving cavity, so that the main body can be covered on the terminal block 21 to receive the terminal block 21 and the terminals 22, 23, 24, 25 mounted on the terminal block 21 therein. The wire passing part 262 has a cylindrical shape and communicates with the inside of the main body 261. The cover 26 is preferably integrally injection molded from plastic.

Preferably, the inner surfaces of the two side walls of the main body 261 are respectively provided with a fastening groove 2611, the two sides of the terminal seat 21 are respectively provided with a fastening protrusion 214 protruding outwards, and the fastening protrusions 214 can be fastened in the fastening grooves 2611, so as to fix the terminal seat 21 in the main body 261.

The outer surfaces of the two sidewalls of the main body 261 are further provided with a concave guide groove 2612 and a concave locking groove 2613. The guide groove 2612 and the locking groove 2613 both extend in the vertical direction of the body 261, the guide groove 2612 penetrates the upper surface and the lower surface of the body 261, and the lower end of the locking groove 2613 penetrates the lower surface of the body 261 and the upper end is closed. The guide groove 2612 is located a distance forward of the locking groove 2613.

The outer surfaces of the two side walls of the main body 261 are further provided with a limiting protrusion 2614 protruding outwards, and the limiting protrusion 2614 is long and extends in the front-back direction. The retaining protrusion 2614 is located above the locking groove 2613.

Still referring to fig. 10, the locking slide 27 includes a top plate 271 and two side plates 272 bent downward from two sides of the top plate 271. The locking slide 27 is preferably formed by bending a metal piece. The locking slide cover 27 serves as a shielding cover to provide shielding function, and is also used to cooperate with the first connector 1 to achieve locking function.

The lower end of each side plate 272 is bent outward to form two snap tabs 2721 spaced from each other in the front-back direction; each of the catch tabs 2721 extends horizontally in the front-rear direction parallel to the top plate 271. A locking protrusion 2722 protruding toward the other side plate 272 is further provided at the lower end of each side plate 272 between the two snap tabs 2721, and the locking protrusion 2722 may be formed by punching inward on the outer surface of the side plate 272; the locking protrusion 2722 extends along the vertical direction of the side plate 272, and the height of the locking protrusion 2722 matches the height of the locking groove 2613 on the main body 261. Above the locking protrusion 2722, the side plate 272 further has a limiting hole 2723, and the limiting hole 2723 is elongated and extends horizontally in the front-rear direction. In addition, the side plate 272 is further provided with an actuating portion 2724 bending outward, and the actuating portion 2724 extends in the vertical direction and is perpendicular to the top plate 271; the actuating portion 2724 can be formed by punching a fracture in the side plate 272 and bending the side plate outward from the fracture.

Referring to fig. 9 and 10, the locking slide 27 is mounted on the cover 26, the top plate 271 covers the upper surface of the main body 261, and the side plate 272 covers the outer side surface of the main body 261. During assembly, the locking protrusion 2722 can move up and down along the guiding groove 2612 of the main body 261, so that the locking slide cover 27 can be covered on the cover 26 from top to bottom. After the assembly is completed, the limiting protrusion 2614 is located in the limiting hole 2723 and can limit the range of the front-back movement of the locking slide cover 27, and the cooperation of the limiting protrusion 2614 and the limiting hole 2723 prevents the locking slide cover 27 and the cover body 26 from being separated from each other up and down, but allows the locking slide cover 27 to move back and forth within a certain range relative to the cover body 26.

The guide groove 2612 and the locking groove 2613 on the cover 26 limit the front and back sliding position of the locking slide cover 27, and the cross sections of the guide groove 2612 and the locking groove 2613 are both concave circular arcs, which is beneficial to preventing the locking protrusion 2722 from sliding improperly. Specifically, when the locking slide 27 is located at the front limit position, the locking protrusion 2722 is fittingly received in the guiding groove 2612; when the locking slide cover 27 is located at the rear limit position, the locking protrusion 2722 is fittingly received in the locking groove 2613. Since the guiding groove 2612 and the locking groove 2613 are both concave relative to the outer surface of the main body 261, the locking protrusion 2722 can be well received, and sufficient holding force is generated to keep the position of the locking slide cover 27 not susceptible to unexpected unlocking caused by the influence of improper external force.

When the front and rear positions of the locking slide cover 27 need to be changed, the actuating portion 2724 can be pushed and pulled to drive the locking slide cover 27 to slide back and forth, which is convenient for operation.

Referring to fig. 8 and 9, the cable 29 includes a plurality of wires 291 and a sheath 292 covering the plurality of wires 291. The ends of the plurality of wires 291 extend forward from the sheath 292 and into the main body 261 through the wire guiding portion 262 of the cover 26. The plurality of wires 291 are used for power transmission and signal transmission, and are electrically connected to the second power terminal 22, the second signal terminal 23, and the second brake terminal 24, respectively (illustration of specific connection relation is omitted in the figure). The rear end of the second ground terminal 25 is wrapped around the ground wire of the cable 29 for grounding. The cap 28 is sleeved on the periphery of the wire passing part 262 and protects the cable 29.

The assembly process of the second connector 2 is substantially: the second power terminal 22, the second signal terminal 23, the second brake terminal 24 and the second ground terminal 25 are respectively and correspondingly installed in the terminal base 21, the front end of the cable 29 passes through the wire passing portion 262 of the cover 26, each conducting wire 291 of the cable 29 is correspondingly connected with each terminal 22, 23, 24, 25, the terminal base 21 is installed in the main body 261 of the cover 26 for fixation, the sealing cap 28 is fixed on the wire passing portion 262 after the cable 29 is arranged, and finally the locking sliding cover 27 is installed on the cover 26.

Referring back to fig. 1 to 4 in conjunction with the description of the first connector 1, the first connector 1 is first fixedly mounted on the motor main body 400, and then the second connector 2 is inserted and mounted on the first connector 1, the cover 26 of the second connector 2 is covered on the first connector 1, the lower end of the terminal base 21 of the second connector 2 is inserted into the upper protruding portion 113 of the first connector 1, so that the second power terminal 22 is electrically connected to the first power terminal 12 and one of the first ground terminals 156, the second signal terminal 23 is electrically connected to the first signal terminal 13, the second brake terminal 24 is electrically connected to the first brake terminal 14, and the second ground terminal 25 is electrically connected to the other first ground terminal 156 (the corresponding relationship between the terminals can refer to fig. 6 and 12).

The locking slide 27 of the second connector 2 is at the front limit position in the initial state, that is, the locking protrusion 2722 of the locking slide 27 is received in the guiding slot 2612 of the cover 26, and at this time, the locking protrusion 2721 of the locking slide 27 is separated from the hook 153 of the locking plate 15 of the first connector 1. When the locking slide 27 is pushed to move backward to the rear limit position, the latching protrusion 2721 will horizontally enter the latching slot 154 of the latching hook 153 backward and be latched, so as to lock the first connector 1 and the second connector 2 together, so that the second connector 2 cannot be separated from the first connector 1. At this time, the locking protrusion 2722 is received in the locking groove 2613 to prevent the locking slide 27 from sliding forward in a reverse direction, so that the locking slide 27 can be kept in a locked state and is not easily affected by an external force to cause an accidental unlocking.
