As shown in fig. 1-6, embodiments of the present disclosure provide a terminal block including an insulating base 100 and a protective assembly. Wherein, the first surface 101 of the insulating base 100 is provided with an electrical groove 110; the electrical slot 110 comprises two wire pressing cavities, each wire pressing cavity is provided with a conducting strip 130 and a fastener 140, the conducting strips 130 of the two wire pressing cavities are conducted, and the fastener 140 is used for fastening the end part of a lead on the conducting strip 130 of the same wire pressing cavity; the protection assembly includes a protection groove 160 and a PTC protector 120; wherein, the protection slot 160 is opened on the second surface 102 of the insulation base 100, and parts of the two conducting strips 130 are located in the protection slot 160; the PTC protector 120 is disposed in the protective groove 160, and two lead terminals of the PTC protector 120 are connected to the two conductive sheets 130, respectively.

In this embodiment, the PTC protector 120 (Positive Temperature Coefficient) is a Positive Temperature Coefficient thermistor protector, and its working principle is that its resistance value is very small when the circuit normally works, and when the circuit appears overcurrent and its Temperature rises, its resistance value increases several orders of magnitude sharply, so that the current in the circuit decreases below the safe value, and the effect is equivalent to the switch disconnection, so that the following circuit is protected, and after the overcurrent disappears, it automatically recovers to low resistance value. Thus, the PTC protector 120 is also called a resettable fuse, a self-resetting overcurrent protector, or the like.

With the terminal block provided by the embodiment of the present disclosure, the two wire pressing cavities are respectively referred to as a first wire pressing cavity 111 and a second wire pressing cavity 112, the conducting strip 130 and the fastener 140 located in the first wire pressing cavity 111 are referred to as a first conducting strip 131 and a first fastener, and the conducting strip 130 and the fastener 140 located in the second wire pressing cavity 112 are referred to as a second conducting strip 132 and a second fastener. When the terminal block is used, the end of a section of wire extends into the first wire pressing cavity 111 and is fastened to the first conducting strip 131 by using a first fastener; the end of another length of wire extends into the second crimping chamber 112 and is fastened to the second conductive tab 132 using a second fastener. Thus, the two segments of wires are conducted through the conducting strip 130. Since the two lead terminals of the PTC protector 120 are connected to the two conductive sheets 130 extending into the protection slot 160, respectively, the resistance of the PTC protector 120 increases sharply when an overcurrent occurs in the circuit, which is equivalent to a switch disconnection, thereby performing a protection function. When the overcurrent disappears, the resistance of the PTC protector 120 automatically recovers, and the circuit is turned on again. Based on the structural design of the terminal block, the PTC protector 120 can perform overcurrent protection without complex wiring, and can be reused without replacement.

Alternatively, as shown in fig. 1 and 3, the fastener 140 includes a fixing pressing piece 141 and a compression screw 142. The end of the wire extends into the wire pressing cavity, and then the compression screw 142 is screwed to drive the fixing pressing sheet 141 to move towards the wire pressing cavity, so that the conducting strip 130 is tightly contacted with the end of the wire through the fixing pressing sheet 141.

Optionally, the first surface 101 is a front surface of the insulating base 100, and the second surface 102 is a back surface of the insulating base 100; the projection of the protective groove 160 on the first surface 101 is located between the two crimping cavities.

In this embodiment, the front surface of the insulating base 100 is the first surface 101, which facilitates the end of the wire to be inserted into the wire pressing cavity and also facilitates the user to fasten the wire to the conductive sheet 130 by the fastening member 140. The PTC protector 120 does not need to be replaced, so the protection groove 160 is opened on the back surface of the insulation base 100, and more operation space is reserved for the front surface of the insulation base 100. The line pressing cavities are concavely formed from the first surface 101 to the second surface 102, the protection groove 160 is concavely formed from the second surface 102 to the first surface 101, and the projection of the protection groove 160 on the first surface 101 is located between the two line pressing cavities, so that a pattern that the first line pressing cavity 111, the protection groove 160 and the second line pressing cavity 112 are sequentially arranged is formed. In this way, the conductive strips 130 of the two wire crimping chambers are facilitated to partially extend into the protective slots 160.

Optionally, two wire pressing cavities of the electrical groove 110 are respectively located at the upper part and the lower part of the first surface 101; the projection of the protection groove 160 on the first surface 101 is located in the middle of the first surface 101.

In the embodiment, when the terminal block is vertically arranged, the first wire pressing cavity 111, the protection groove 160 and the second wire pressing cavity 112 are sequentially arranged from top to bottom, as shown in fig. 2. The mouths of the first and second crimping cavities 111 and 112 are located on the first surface 101 and the mouths of the guard groove 160 are located on the second surface 102. As shown in fig. 5, the lower side of the first conductive sheet 131 in the first wire pressing chamber 111 extends into the protective groove 160, and the upper side of the second conductive sheet 132 in the second wire pressing chamber 112 extends into the protective groove 160. And, the lower side of the first conductive sheet 131 is provided with a connection hole, and the upper side of the second conductive sheet 132 is provided with a connection hole, which are respectively used for connecting two lead terminals of the PTC protector 120.

Optionally, as shown in fig. 6, the protection assembly further includes an insulating cover plate 150, and the insulating cover plate 150 is detachably disposed at the notch of the protection groove 160.

In another example, the protection slot 160 is provided with a slot on both sides of the slot, and the insulating cover 150 is provided with a clip on both sides of the slot. During installation, the fasteners of the insulating cover 150 are engaged with the slots on both sides of the slot opening, thereby sealing the protection slot 160. The insulating cover plate 150 can be detached by releasing the fasteners of the insulating cover plate 150 from the slots on both sides of the notch, thereby avoiding the protective groove 160.

As another example, the insulating cover 150 may be provided with fixing holes at four corners thereof, and the insulating cover 150 may be fixed to the notches of the protective grooves 160 using bolt fasteners adapted to the fixing holes, thereby closing the protective grooves 160. The insulating cover 150 can be removed by loosening the bolt fasteners at the four corners of the insulating cover 150, thereby avoiding the protective groove 160.

Furthermore, a plurality of PTC protectors 120 are disposed in the protection slot 160, and two lead terminals of each PTC protector 120 are respectively connected to two conductive sheets 130 of the same set of electrical slots 110. Thus, each wire of the circuit connected by the wiring terminal block plays a role in overcurrent protection. When any wire is in an overcurrent state, the resistance value of the PTC protector 120 corresponding to the wire is sharply increased, which is equivalent to the disconnection of a switch, thereby playing a role in protection. When the overcurrent disappears, the resistance of the PTC protector 120 corresponding to the wire automatically recovers, and the wire is turned on again.
