[0041] This embodiment provides a terminal block, which includes an insulating base 1 and a plurality of terminal blocks 2 disposed in the insulating base 1. The terminal blocks 2 are preferably long copper plate structures.

[0042] like Figures 1 to 8 As shown, the insulating base 1 includes several terminal mounting structures 11. The terminal mounting structures 11 are divided into two groups. The first group of terminal mounting structures 11 is located to one side of the second group of terminal mounting structures 11 in the height direction of the insulating base 1. The terminal mounting structures 11 in each group are distributed along the width direction of the insulating base 1. The wiring terminals 2 correspond one-to-one with the terminal mounting structures 11. Each wiring terminal 2 is installed in the corresponding terminal mounting structure 11 and can be adjusted to move along the length direction of the insulating base 1 within the corresponding terminal mounting structure 11.

[0043] In a further embodiment, the length of the terminal mounting structure 11 coincides with the length of the insulating base 1. The terminal mounting structure 11 includes a slot portion 111 and a groove portion 112 along its length. The slot portion 111 defines a receiving cavity that communicates with the inner cavity of the groove portion 112. The slot portion 111 has an insertion opening 1111 at one end away from the groove portion 112. The slot portion 111 has a first opening 1112 on one side of the height of the insulating base 1, extending to the insertion opening 1111. The first opening 1112 and the insertion opening 1111 each communicate with the receiving cavity, allowing the terminal 2 to be installed in the receiving cavity of the slot portion 111 through the insertion opening 1111. The first opening 1112 facilitates connection of the terminal 2. The groove portion 112 has a second opening 1121 that communicates with the inner cavity of the slot portion 111. An opening direction of the second opening 1121 is consistent with an opening direction of the first opening 1112 .

[0044] The first terminal mounting structure 11 is located on the side of the second mounting structure opening, between the first opening 1112 and the second opening 1121 of the second mounting structure. The insulating base 1 also includes a fixing plate 12, which is positioned corresponding to the slide slot 111. The length of the fixing plate 12 is aligned with the width of the insulating base 1, and the width of the fixing plate 12 is aligned with the height of the insulating base 1. Several fixing holes are provided on the fixing plate 12 to securely mount the entire terminal block.

[0045] In a further embodiment, the groove portion 112 is provided with side plates 1122 on both sides of the insulating seat 1 in the width direction, and one end of the side plate 1122 extends to the slide groove portion 111. Preferably, the two adjacent terminal mounting structures 11 in each group share a side plate 1122, and the other end of the side plate 1122 in the second group of terminal mounting structures 11 extends outward to form a blocking plate, such as Figure 1 and Figure 3As shown. Two adjacent copper noses can be blocked during wiring to prevent short circuits and ensure the safety of the connection lines. The first group of terminal mounting structures 11 and the second group of terminal mounting structures 11 are staggered. In the second group of terminal mounting structures 11, the side panels 1122 between the two adjacent terminal mounting structures 11 are provided with chamfers 1123 at positions corresponding to the second openings 1121. In this way, the multiple terminal mounting structures 11 located in the lower layer and the side panels 1122 between the adjacent terminal mounting structures 11 are chamfered, which can prevent the upper terminal mounting structure 11 from interfering due to the thickness of the outer rubber layer of the cable during wiring, which is beneficial to the bundling of the cables without the need to remove too much of the outer rubber layer of the cables, thereby improving the stability and safety of the cable connection.

[0046] In a further embodiment, the length direction of the terminal block 2 is consistent with the length direction of the insulating base 1. The terminal block 2 has a first terminal 21 and a second terminal 22 along the length direction. Figure 9 As shown. The terminal block 2 is provided with a first connection hole 23 and a second connection hole 24 at positions close to the first terminal block 21 and the second terminal block 22, respectively. The terminal block 2 is fixedly provided with a first connection member 4 at a position corresponding to the first connection hole 23, and the terminal block 2 is fixedly provided with a second connection member 5 at a position corresponding to the second connection hole 24. The first connection member (4) and the second connection member (5) are respectively provided with threaded holes. Preferably, the first connection member 4 and the second connection member 5 are rivet nuts, which can be fixedly installed in the first connection hole 23 and the second connection hole 24 by pressing or the like. Of course, the first connection member 4 and the second connection member 5 are not limited to this and can also be other structures, such as metal sheet stamping parts, which are then fixed to the terminal block 2 by bolt fastening or the like, and threaded holes are opened at positions corresponding to the first connection hole 23 or the second connection hole 24, which can also achieve the same technical effect.

[0047] When the terminal 2 is installed in the terminal mounting structure 11, the terminal 2 has a first connection position and a second connection position relative to the terminal mounting structure 11. The terminal 2 can be adjusted to move between the first connection position and the second connection position along the length direction of the insulating base 1 in the terminal mounting structure 11. When the terminal 2 is in the first connection position, the first connection end 21 corresponds to the first opening 1112. Figure 13 When the connection terminal 2 is located at the second connection position, the second connection terminal 22 is located in the groove portion 112 and corresponds to the second opening 1121. Figure 15 shown.

[0048] The specific technical solution is: a plurality of sliding members 3 are provided, and the sliding members 3 correspond to the terminal blocks 2 one by one. The terminal blocks 2 are mounted on the corresponding sliding members 3. The first sliding grooves 113 are provided on the two inner walls of the insulating seat 1 in the width direction. Figure 2 and Figure 5 As shown. The length direction of the first chute 113 is consistent with the length direction of the insulating base 1. One end of the first chute 113 in the length direction passes through the end of the chute portion 111 away from the groove portion 112, and the other end of the first chute 113 in the length direction extends to the inner wall of the groove portion 112 away from the chute portion 111. When the terminal 2 is installed in the terminal mounting structure 11, the two ends of the terminal 2 in the width direction are slidably mounted in the two first chute slots 113, so that the terminal 2 can be adjusted along the length direction of the insulating base 1 within the mounting structure via the slider 3.

[0049] The sliding member 3 has a clamping portion 31, a connecting portion 32 and a contact portion 33 in sequence along the length direction. Preferably, the sliding member 3 is H-shaped, such as Figure 10As shown. The engaging portion 31 includes a plurality of first engaging claws 311 and a plurality of second engaging claws 312. The length directions of the first engaging claws 311 and the second engaging claws 312 are respectively aligned with the length directions of the sliding member 3. The first engaging claws 311 engage with the two inner walls of the chute portion 111 in the width direction of the insulating seat 1. The second engaging claws 312 engage with the inner wall of the chute portion 111 opposite the first opening 1112. The sliding member 3 schematically shown in the figure is provided with two first engaging claws 311 and two second engaging claws 312. The two first engaging claws 311 are spaced apart along the width direction of the sliding member 3. The first engaging claws 311 are provided with a first engaging protrusion, which faces the corresponding inner wall of the chute portion 111 in the width direction of the insulating seat 1. The two second engaging claws 312 are spaced apart along the width direction of the sliding member 3, and the second engaging claws 312 are located on one side of the first engaging claw 311 in the height direction of the sliding member 3. The second claw 312 is provided with a second latching protrusion, and the second latching protrusion faces the inner wall of the slide groove part 111 opposite to the first opening 1112, that is, the direction away from the first claw 311. It should be noted that the number of the first claw 311 and the second claw 312 is not limited to two, and can also be other multiples, and the number can be an even number or an odd number. For example, the first claw 311 can be four, and two are arranged in a group, and the two in each group are distributed along the height of the sliding member 3. It can also be three, with two first claws 311 on one side and one first claw 311 on the other side, etc. The interference portion 33 of the sliding member 3 includes two interference arms 331. The length direction of the interference arm 331 is consistent with the length direction of the sliding member 3, and the two interference arms 331 are arranged at intervals along the width direction of the sliding member 3. When the terminal block 2 is mounted on the sliding member 3, the first connecting member 4 is located between a plurality of first claws 311 that are spaced apart, and the second connecting member 5 is located between two abutting arms 331 that are spaced apart. Figure 11 This structural design facilitates installation by simply pressing the side of the terminal 2 with the nut onto the slider 3. Furthermore, the connection portion 32 of the slider 3 is located between the first connector 4 and the second connector 5, preventing the terminal 2 from shifting relative to the slider 3 in the longitudinal direction of the slider 3. The terminal 2 and slider 3 are then installed together through the insertion opening 1111 of the terminal mounting structure 11 into the accommodating cavity of the slide groove 111, with the terminal 2 positioned on the side closest to the first opening 1112.

[0050] like Figure 2 、 Figure 4 and Figure 5As shown. The slide groove portion 111 is provided with a first latching groove 114 and a second latching groove 115 at positions corresponding to the first latching protrusion on the two inner walls in the width direction of the insulating seat body 1. The slide groove portion 111 is provided with a second slide groove 116 at positions corresponding to the second latching protrusion on the inner wall opposite to the first opening 1112. The length direction of the first latching groove 114, the length direction of the second latching groove 115 and the length direction of the second slide groove 116 are respectively consistent with the length direction of the insulating seat body 1. When the wiring terminal 2 is installed in the terminal mounting structure 11, the first latching protrusion of the sliding member 3 can be engaged with the corresponding first latching groove 114 or second latching groove 115. The second latching protrusion of the sliding member 3 is located in the corresponding second slide groove 116. When the connecting terminal 2 is in the first connection position, the first latching protrusion of the sliding member 3 is engaged with the corresponding first latching groove 114. At this time, the side wall of the first latching groove 114 close to the groove portion 112 can limit the movement of the sliding member 3 in the direction of the groove portion 112, and the side wall of the second slide groove 116 away from the groove portion 112 can limit the movement of the sliding member 3 in the direction away from the groove portion 112. When the connecting terminal 2 is in the second connection position, the first latching protrusion of the sliding member 3 is engaged with the corresponding second latching groove 115. At this time, the side wall of the second latching groove 115 away from the groove portion 112 can limit the movement of the sliding member 3 in the direction away from the groove portion 112, and the connecting terminal 2 contacts the side wall of the groove portion 112 away from the slide groove portion 111, thereby limiting the sliding member 3 from continuing to move in the direction of the groove portion 112.

[0051] In a further embodiment, Figure 2 and Figure 5 As shown. One end of the first slot 114 extends along its length through the end of the slide portion 111 away from the groove portion 112. One end of the second slot 115 extends along its length to and through the end of the groove portion 112 away from the slide portion 111. One end of the second slide 116 extends along its length to and through the end of the groove portion 112 away from the slide portion 111. After the terminal block 2 is installed in the insulating base 1, a dedicated tool can be inserted into the second slot 115 or the second slide 116 to engage the first or second latching protrusion to unlock and remove the terminal block 2.

[0052] In a further embodiment, a notch 332 is provided at one end of the interference arm 331 away from the connecting portion 32 in the length direction. Figure 10As shown. A through hole is provided at the end of the groove portion 112 away from the slide portion 111, corresponding to the position of the interference arm 331. The through hole is connected to the corresponding second slot 115 and the second slide portion 116. When the terminal 2 is in the second wiring position, one end of the interference arm 331 can be inserted into the corresponding through hole. The notch 332 on the interference arm 331 forms a contact surface that just contacts the inner wall of the groove portion 112 away from the slide portion 111. This structural design can further limit the sliding member 3 and improve stability during wiring.

[0053] The installation steps of the terminal block in this application are as follows:

[0054] The first connecting member 4 and the second connecting member 5 are respectively pressed onto the first connecting hole 23 and the second connecting hole 24 on the terminal 2, and then the terminal 2 with the nut pressed onto it is clamped onto the sliding member 3. Then, the terminal 2 and the sliding member 3 are installed together from the insertion port 1111 of the terminal mounting structure 11 into the terminal mounting structure 11 until the second cam on the sliding member 3 is snapped into the second slide groove 116. The first cam just contacts the side wall of the first slot 114 close to the groove portion 112. This is the first wiring position. The first copper nose 6 can be fastened to the terminal 2 using fasteners such as bolt structures to achieve communication. Figure 12 and Figure 13 Then, the sliding member 3 or the terminal 2 is pushed toward the groove portion 112 until the first protrusion is engaged with the second groove 115, and the terminal 2 and the contact arm 331 of the sliding member 3 contact the inner wall of the groove portion 112 away from the slide portion 111. This is the second connection position, and the second copper nose 7 can be fastened to the terminal 2 using a fastener such as a bolt structure to achieve connection, as shown in FIG. Figure 14 and Figure 15 shown.

[0055] Compared with the prior art, the terminal block of the present application has at least one or more of the following beneficial effects:

[0056] (1) The terminal block of the present application has terminals arranged in two rows, which can effectively reduce the length of the terminal block and thus does not require a large installation space during installation, thereby contributing to the miniaturization of the device and improving the space utilization of the device;
