Description

Terminals

Technical field

The invention relates to the field of electrical machinery, and in particular to a terminal block.

Background technique

The resistance cable of the capacitive contactor is connected between the main circuit and the auxiliary switching circuit of the capacitive contactor to achieve peak current shunting in the initial stage of switching on the capacitive contactor. The contactor body of the capacitive contactor has a wiring conductor row connected to the main circuit. The resistance cable contacts the wiring conductor row through a terminal fixed at one end thereof to conduct communication with the main circuit. The connection terminal can be pressed against the connection conductor bar through the resisting member of the connection frame of the connection box. With current wiring terminals, if the resisting member becomes loose, the wiring terminal will fall off from the wiring frame. When the user reconnects, the resistor cables of each phase are easily connected in the wrong position, causing a short circuit in the capacitive contactor.

Contents of the invention

The object of the present invention is to provide a wiring terminal that is not easy to fall off from the wiring frame.

The invention provides a wiring terminal. Terminal blocks are used to connect to wiring racks. The patch panel has two side walls. The two side walls are spaced apart along a first direction of the wiring frame. The wiring frame forms a space between the two side walls that runs through the wiring frame along a second direction, wherein the second direction is perpendicular to the first direction. The terminal block includes a contact part, a connecting part and a limiting part. The contact portion is used to make electrical conductive contact with the terminal of the device. The connection part connects the contact part and is used to fix the connection cable. The limiting part is connected to the contact part. The width of the limiting portion along a first width direction of the wiring terminal is smaller than the width of the limiting portion along a second width direction of the wiring terminal, wherein the first width direction and the second width direction are both perpendicular to a length direction of the wiring terminal, When the length direction is parallel to the second direction and the first width direction is parallel to the first direction, the limiting portion can pass through the separation space along the second direction, and the length direction is parallel to the second direction and the second width direction. When parallel to the first direction, the two ends of the limiting portion along the second width direction can respectively abut against the two side walls in the opposite direction of the second direction.

The width of the limiting part along the first width direction of the wiring terminal is smaller than the width of the limiting part along the second width direction, so that it can pass through the separation space of the wiring frame by adjusting the angle, and can also pass through the separation space after passing through the separation space. Adjust the angle against the wiring frame so that the terminal block does not fall off easily from the wiring frame.

In another illustrative embodiment of the connection terminal, the limiting portion and the connecting portion are respectively provided on both sides of the contact portion along the length direction. This can facilitate the electrical conduction between the contact portion and the terminal of the device.

In another illustrative embodiment of the connection terminal, the limiting portion is flat-shaped and arranged perpendicularly to the length direction, thereby saving space.

In yet another illustrative embodiment of the connection terminal, the limiting portion is rectangular. This helps to increase the area of the limiting portion for abutting against the side wall and increases the difficulty for the terminal to fall off from the wiring frame.

In yet another illustrative embodiment of the connection terminal, the contact portion is in the shape of a flat plate parallel to the length direction and the second width direction. This facilitates conductive contact with the flat terminal of the device.

In another illustrative embodiment of the terminal, the contact portion and the limiting portion are made of the same plate material. The contact portion and the limiting portion are formed by bending the plate portion forming the contact portion and the limiting portion at 90 degrees along a folding line parallel to the second width direction. This facilitates processing.

In yet another illustrative embodiment of the connection terminal, the connection terminal further includes two pressing parts. Each pressing portion extends along the length direction. The two pressing parts connect the plate surfaces on the same side of the contact part and are respectively provided at both ends of the contact part along the second width direction. This can improve the contact tightness between the terminal and the terminal of the device under the abutment of the resisting member.

In another illustrative embodiment of the terminal, the contact portion and the two pressing portions are made of the same plate material. The plate portion forming the contact portion and the two resisting portions is rectangular. The contact portion and the two pressing portions are formed by folding two opposite sides of the rectangular plate portion along fold lines parallel to the sides. This facilitates processing.

In yet another illustrative embodiment of the connection terminal, the connection part includes a main body part, two first fastening parts and two second fastening parts. The main body part is connected to the contact part. The two first fastening parts respectively connect two ends of the main body part along a distribution direction of the main body part and are arranged oppositely along the distribution direction. The two first fastening parts can be bent relatively along the distribution direction to embrace the cable from the outside of the outer insulation layer of the cable along the circumferential direction of the cable. The two second fastening parts are respectively connected to two ends of the main body part along the distribution direction and are arranged oppositely along the distribution direction. The two second fastening parts can be folded on the main body part to clamp the wires of the cable with the main body part. This makes it easier to connect cables.

In another illustrative embodiment of the terminal, the main body, the two first fastening parts and the two second fastening parts are made of the same plate material. The main body part is in the shape of a flat plate parallel to the distribution direction, wherein the distribution direction is parallel to the second width direction. The main body part is in a long strip shape extending along one wiring direction of the terminal, wherein the wiring direction is perpendicular to the second width direction. One end of the main body along the wiring direction is connected to the contact portion. The two second fastening parts are closer to one end of the connecting contact part of the main body than the two first fastening parts. This makes it easier to connect cables.

In this article, "first", "second", etc. do not indicate their importance or order, etc., but are only used to indicate the difference between them to facilitate the description of the document.

In order to keep the drawings concise, only the parts related to the present invention are schematically shown in each figure, and they do not represent the actual structure of the product.

Figure 1 is a schematic structural diagram of a schematic implementation of a terminal. The terminal block 100 is used to connect the terminal frame of the terminal box. As shown in FIG. 7 , the junction box 200 includes, for example, a housing 70 and a wiring frame 60 disposed in the housing 70 . The wiring frame 60 includes, for example, a frame body 61 and a resisting member 63 . The junction box 200 is, for example, installed on the device 300 for electrical conduction between the terminals 301 of the device and the terminals. For example, the resisting member 63 can move downward relative to the frame 61 to clamp the terminal 301 with the terminal 301 . The device 300 is, for example, a capacitive contactor, and the terminal 301 of the device is, for example, a wiring conductor row connected to the main circuit of the capacitive contactor, but is not limited thereto.

As shown in FIGS. 2 and 3 , the frame body 61 has two side walls 65 . The two side walls 65 are spaced apart along a first direction D1 of the wiring frame 60 . The frame body 61 forms an interval space 62 between the two side walls 65 that runs through the wiring frame 60 along a second direction D2, where the second direction D2 is perpendicular to the first direction D1.

As shown in FIG. 1 , the terminal 100 includes a contact part 10 , a connecting part 30 and a limiting part 50 . The contact portion 10 is used to make electrical contact with the terminal of the device. The connection part 30 is connected to the contact part 10 and used to fix the connection cable. The cable is, for example, a resistance cable of a capacitor contactor, but is not limited thereto. The limiting part 50 is connected to the contact part 10 . The width of the limiting portion 50 along a first width direction W1 of the wiring terminal 100 is smaller than the width of the limiting portion 50 along a second width direction W2 of the wiring terminal 100 , wherein the first width direction W1 and the second width direction W2 are both vertical. in one length direction L of the terminal 100 . The first width direction W1 is, for example, perpendicular to the second width direction W2, but is not limited thereto. As shown in FIG. 2 , when the length direction L is parallel to the second direction D2 and the first width direction W1 is parallel to the first direction D1 , the limiting portion 50 can pass through the separation space 62 along the second direction D2 and be as follows: As shown in FIG. 3 , when the length direction L is parallel to the second direction D2 and the second width direction W2 is parallel to the first direction D1 , the two ends of the limiting portion 50 along the second width direction W2 can respectively move along the second direction D1 . The opposite direction of direction D2 abuts the two side walls 65 .

During installation, first insert the wiring terminal 100 into the separation space 62 along the second direction D2 with the length direction L parallel to the second direction D2, and then adjust the angle of the wiring terminal 100 so that the limiting portion 50 can move in the opposite direction of the second direction D2. The second direction D2 abuts against the two side walls 65 , thereby preventing the terminal 100 from falling off the wiring frame 60 in the opposite direction of the second direction D2 . Then, as shown in FIG. 4 , for example, the terminal 301 of the device is inserted into the separation space 62 and located on the lower side of the terminal 100 , and then the resisting member 63 is moved downward so that the resisting member 63 is clamped with the terminal 301 of the device. The contact portion 10 is tightly attached to the terminal 100 of the device, thereby achieving conductive contact between the terminal 301 of the device and the terminal 100 .

When the resisting member 63 is loose, the terminal 100 can only move along the second direction when the limiting portion 50 does not abut the side wall 65 in the opposite direction of the second direction D2 (for example, the angle shown in FIG. 2 ). The opposite direction of direction D2 is removed from the wiring frame 60 . In addition, the terminal block 100 may also be restricted by the terminal 301 and the resisting member 63 of the device and cannot be rotated to an angle at which it can be detached from the wiring frame 60 in the opposite direction of the second direction D2.

The width of the limiting part along the first width direction of the wiring terminal is smaller than the width of the limiting part along the second width direction, so that it can pass through the separation space of the wiring frame by adjusting the angle, and can also pass through the separation space after passing through the separation space. Adjust the angle against the wiring frame so that the terminal block does not fall off easily from the wiring frame.

As shown in FIG. 1 , in the exemplary embodiment, the limiting portion 50 and the connecting portion 30 are respectively provided on both sides of the contact portion 10 along the length direction L. This can facilitate the electrical conduction between the contact portion and the terminal of the device, but is not limited thereto.

Two adjacent sides of the rectangle are respectively parallel to the first width direction W1 and the second width direction W2. This helps to increase the area of the limiting portion 50 for abutting against the side wall 65 and increases the difficulty of detaching the terminal 100 from the wiring frame 60 . However, it is not limited thereto. In other exemplary embodiments, the limiting part 50 may also be provided in other shapes.

As shown in FIG. 1 , in the exemplary embodiment, the contact portion 10 has a flat plate shape parallel to the longitudinal direction L and the second width direction W2 . This facilitates conductive contact with the flat terminal of the device.

The contact portion 10 and the limiting portion 50 are formed by bending the plate portion forming the contact portion 10 and the limiting portion 50 at 90 degrees along a folding line parallel to the second width direction W2. This facilitates processing.

As shown in FIG. 1 , in the exemplary embodiment, the connection terminal 100 further includes two pressing parts 20 . Each pressing portion 20 extends along the length direction L. The two pressing portions 20 connect the same side plate surfaces of the contact portion 10 and are respectively provided at both ends of the contact portion 10 along the second width direction W2. As shown in Figure 4, the two resisting parts 20 match the inverted "V"-shaped structure at the lower end of the resisting member 63, and the resisting member 63 respectively abuts two protrusions of the inverted "V"-shaped structure. The pressing portion 20 presses the contact portion 10 against the terminal 301 of the device. This can improve the contact tightness between the terminal 100 and the terminal of the device under the abutment of the resisting member 63 .

As shown in FIG. 1 , in the exemplary embodiment, the contact portion 10 and the two pressing portions 20 are made of the same plate material.

In this exemplary embodiment, the distribution direction is, for example, parallel to the second width direction W2. The two second fastening parts 34 respectively connect the two ends of the main body part 31 along the distribution direction and are oppositely arranged along the distribution direction. The two first fastening parts 33 can be bent relatively along the distribution direction to embrace the cable from the outside of the outer insulation layer of the cable along the circumferential direction of the cable. The two second fastening parts 34 can be folded on the main body part 31 to clamp the wires of the cable with the main body part 31 . FIG. 5 shows a state in which the first fastening part 33 and the second fastening part 34 are bent to fix the connection cable 400 and clamp the wire 401 of the cable.

As shown in FIG. 1 , in the illustrative embodiment, the main body part 31 , the two first fastening parts 33 and the two second fastening parts 34 are processed from the same plate material. The main body 31 has a flat plate shape parallel to the distribution direction. The main body portion 31 is in a long strip shape extending along one wiring direction of the terminal 100 , where the wiring direction is perpendicular to the second width direction W2 . In this exemplary embodiment, the wiring direction is parallel to the length direction L, for example. One end of the main body part 31 along the wiring direction is connected to the contact part 10 . The two second fastening parts 34 are closer to one end of the connecting contact part 10 of the main body part 31 than the two first fastening parts 33 . This makes it easier to connect cables.
