A deep groove with an angle of 45° to the length direction of the wiring board is opened axially from the center of the upper end of the bolt. The round holes of the OT terminal, the flat pad and the connecting plate are provided with transverse ribs which are inserted into the deep grooves. The invention fully meets the wiring needs of small and medium-sized motors, saves small parts, makes installation faster, saves costs, and is safe and fast when the motor is connected to the power cable. In theory, only a wire stripper and a wrench are needed, avoiding The process of crimping the OT terminal is required when wiring the traditional terminal board, which is convenient for the motor to be installed on the user's site.

Description

A small and medium-sized motor wiring device

technical field

The invention belongs to the field of electrical technology, in particular to a connection device for small and medium-sized motors.

Background technique

The existing small and medium-sized motor wiring device comprises a wiring board, and the wiring board is vertically provided with six bolts, and the bolts are covered with 12 flat washers, 12 spring washers and 12 bow washers, and 18 nuts are used. Moreover, the process of crimping the OT terminal needs to be carried out during installation, and the wiring is cumbersome, and the OT terminal will swing left and right, which is inconvenient for on-site installation. In addition, too many parts are used, and the installation wastes time and increases costs.

Contents of the invention

In order to solve the deficiencies in the prior art, the present invention provides a wiring device for small and medium-sized motors which is safe, quick and cost-saving.

In order to solve the above technical problems, the present invention adopts the following technical solutions: a small and medium-sized motor wiring device, including a terminal board, six bolts are vertically arranged on the terminal board, and OT terminals are installed on each of the bolts from bottom to top , flat washers, spring washers and nuts, wherein a connecting plate set on the bolts is set between two bolts in the width direction, and the connecting plate is located between the OT terminal and the flat washers.

A deep groove with an angle of 45° to the length direction of the wiring board is opened axially from the center of the upper end of the bolt.

The round holes of the OT terminal, the flat pad and the connecting plate are provided with transverse ribs that are inserted into the deep grooves.

By adopting the above technical scheme, the transverse reinforcement is clamped into the deep groove of the bolt, which can ensure that the OT terminal, the flat pad and the connecting plate do not swing left and right when the nut is tightened. When the power cable is connected, there is no need to add an OT terminal. It is only necessary to peel off the cable to leak the metal wire, and insert the metal wire into the deep groove of the bolt between the flat pad and the connecting plate, because the horizontal rib is added between the flat pad and the connecting plate , When the nut is tightened, it can effectively compress the metal wire and ensure a large enough contact area.

The invention fully meets the wiring needs of small and medium-sized motors, and saves 12 nuts, 6 spring washers, 6 flat washers, and 12 bow-shaped washers compared with the traditional wiring device. The installation is faster and the cost is saved, especially for mass production. In addition, it is safe and fast to connect the motor to the power cable. In theory, only a wire stripper and a wrench are needed, which avoids the process of crimping the OT terminal when wiring the traditional terminal board, and facilitates the motor to be connected to the power cable. User site installation.

Detailed ways

As shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a kind of small and medium-sized motor wiring device of the present invention includes a terminal board 1, and six bolts 2 are vertically arranged on the terminal board 1, and each bolt 2 is OT terminals 3, flat washers 4, spring washers 5 and nuts 6 are installed sequentially from bottom to top, wherein a connecting plate 7 set on the bolt 2 is arranged between the two bolts 2 in the width direction, and the connecting plate 7 It is located between the OT terminal 3 and the flat pad 4. The bolt 2 is axially provided with a deep groove 8 with an angle of 45° with the length direction of the terminal board 1 from the center of the upper end. The round holes of the OT connector 3 , the flat pad 4 and the connecting plate 7 are provided with transverse ribs 9 which are inserted into the deep groove 8 .

The present invention does not need to increase the OT connector when connecting the power cable, only need to peel off the cable to leak the metal wire, and stuff the metal wire into the deep groove 8 of the bolt 2 between the flat pad 4 and the connecting plate 7, because the flat pad 4 and the middle of the connecting plate 7 have increased a transverse rib 9, which can effectively compress the metal wire when the nut 6 is tightened, and ensure a large enough contact area. The transverse rib 9 snaps into the deep groove 8 of the bolt 2, which can ensure that the OT terminal 3, the flat pad 4 and the connecting plate 7 do not swing left and right when the nut 6 is tightened.
