[0024] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.

[0025] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0027] This application provides a piercing connector and an air conditioner to solve the problem of connectors being incompatible with cables of various diameters. The following description is in conjunction with the accompanying drawings.

[0028] This application provides a piercing connector, including a terminal block 1. The terminal block 1 includes a housing 11, a connecting terminal 12, and a wire clamping member 13. The housing 11 has a wiring through groove 113 and a wire clamping groove 114, which communicate with each other. The connecting terminal 12 is disposed in the wiring through groove 113 and includes a piercing portion 121. One end of the wire clamping member 13 extends into the wire clamping groove 114 to push the cable toward the piercing portion 121. The wire clamping member 13 is provided with at least one locking tooth 1331, and the groove wall of the wire clamping groove 114 is provided with multiple grooves 1141, and / or the wire clamping member 13 is provided with multiple grooves 1141, and the groove wall of the wire clamping groove 114 is provided with at least one locking tooth 1331, which engages with any groove 1141.

[0029] By setting the wire clamping component 13, when the cable is placed into the wiring through groove 113, the wire clamping component 13 is placed into the wire clamping groove 114 and pressed towards the connecting terminal 12. The wire clamping component 13 pushes the cable towards the piercing part 121, which pierces the outer insulation layer of the cable and connects with the inner core of the cable, thereby realizing the connection between the cable and the wiring terminal 1. By setting the clamping teeth 1331 on the wire clamping component 13, and opening multiple toothed grooves 1141 on the groove wall of the wire clamping groove 114, and... Alternatively, multiple grooves 1141 may be formed on the wire pressing member 13, and at least one locking tooth 1331 may be provided on the groove wall of the wire pressing groove 1141, so that when cables of different diameters are pressed towards the piercing part 121, the locking tooth 1331 can engage with the groove 1141 at the corresponding position, thereby enabling the wire pressing member 13 to press the cables of different diameters tightly, so that the cables of different diameters can be fixedly connected to the piercing connector, thus solving the problem that the connector is difficult to be compatible with cables of multiple diameters.

[0030] In this embodiment, the housing 11 includes a main body 111 and a plug-in part 112 connected in sequence. The number of plug-in parts 112 is set to four so that the piercing connector can connect to up to four cables at the same time. The four plug-in parts 112 are integrally formed on one side of the main body 111 and are spaced apart. The number of wiring through slots 113 is also set to four. The wiring through slots 113 are arranged one-to-one with the plug-in parts 112 and the wiring through slots 113 pass through the corresponding plug-in parts 112 and the main body 111 in sequence. The wire pressing groove 114 is opened in the main body 111 and is connected to the four wiring through slots 113 so that the wire pressing member 13 can push all the cables to the piercing part 21 at the same time.

[0031] The terminal block 1 also includes an end cap 14. A receiving groove 115 is formed on the side of the main body 111 away from the insertion part 112. The end cap 14 is housed within the receiving groove 115. Multiple locking blocks 141 are provided on the side of the end cap 14. Multiple locking holes 116 are formed on the wall of the receiving groove 115. Each locking hole 116 corresponds to a locking block 141, and the locking block 141 engages with the corresponding locking hole 116 to securely connect the end cap 14 to the housing 11. By providing the end cap 14 on the side of the main body 111 away from the insertion part 112, the connection terminal 12 housed in the wiring through groove 113 can be prevented from sliding out from the side of the main body 111 away from the insertion part 112, which facilitates the installation and transportation of the terminal block 1. In addition, the end cap 14 has four connecting holes 142 for cables to pass through. The connecting holes 142 are corresponding to the wiring slots 113. The connecting holes 142 are connected to the corresponding wiring slots 113, which not only allows the cables to extend from the connecting holes 142 into the wiring slots 113, but also helps to reduce short circuits between cables.

[0032] The wire clamping component 13 includes a wire clamping cover 131, a wire clamping post 132, and multiple connecting blocks 133. The wire clamping post 132 is used to push the cable towards the piercing part 121. The wire clamping post 132 is fixedly connected to the side of the wire clamping cover 131 near the connecting terminal 12. The multiple connecting blocks 133 are all fixedly connected to the side of the wire clamping cover 131 near the groove wall of the wire clamping groove 114. Each connecting block 133 is spaced apart from the wire clamping post 132 so that the connecting block 133 can deform towards one side of the wire clamping post 132 when subjected to force. Each connecting block 133 extends towards one side of the connecting terminal 12. In this embodiment, multiple locking teeth 1331 are integrally formed on the connecting block 133. The multiple locking teeth 1331 are arranged sequentially and spaced apart along the length direction of the connecting block 133. Multiple toothed grooves 1141 that cooperate with the locking teeth 1331 are formed on the groove wall of the wire clamping groove 114. By setting a locking tooth 1331 on the wire pressing member 13 and opening multiple toothed grooves 1141 on the groove wall of the wire pressing groove 114, the locking tooth 1331 can engage with the toothed groove 1141 at the corresponding position when pressing cables of different diameters toward the piercing part 121, thereby enabling the wire pressing member 13 to press cables of different diameters tightly.

[0033] In some embodiments of this application, the connecting block 133 has a plurality of grooves 1141, and the groove wall of the wire pressing groove 114 has a plurality of locking teeth 1331 integrally formed. In other embodiments of this application, the connecting block 133 has a plurality of locking teeth 1331 integrally formed and a plurality of grooves 1141, and the groove wall of the wire pressing groove 114 has a plurality of locking teeth 1331 integrally formed and a plurality of grooves 1141. The locking teeth 1331 on the connecting block 133 engage with the grooves 1141 on the groove wall of the wire pressing groove 114, and the locking teeth 1331 on the groove wall of the wire pressing groove 114 engage with the grooves 1141 on the connecting block 133. By opening multiple grooves 1141 on the wire pressing member 13 and providing at least one locking tooth 1331 on the groove wall of the wire pressing groove 114, the locking tooth 1331 can engage with the corresponding groove 1141 when pressing cables of different diameters toward the piercing part 121, thereby enabling the wire pressing member 13 to press cables of different diameters tightly.

[0034] The piercing connector also includes a base 2, which includes a seat 21 and a pin 22. The seat 21 has a mounting groove 23, and the pin 22 is disposed within the mounting groove 23. In this embodiment, the base 2 is disposed on a printed circuit board, and the pin 22 is fixedly connected to the printed circuit board. At least one plug portion 112 has an integrally formed guide strip 117. Specifically, there are two guide strips 117, each disposed on one of the two plug portions 117, and the two guide strips 117 are asymmetrically arranged. The mounting groove 23 has a guide groove 26 that mates with the guide strip 117. The mating of the guide strip 117 and the guide groove 26 facilitates the insertion of the plug portion 112 into the base 2. By making the two guide strips 117 asymmetrically arranged, it helps guide the operator to correctly insert the terminal 1 into the base 2, reducing the occurrence of misinsertion. The terminal 1 is provided with a latch 118, and the base 2 is provided with a latching block 24, which has a latching hole 25. When the terminal block 1 is connected to the base 2, one end of the terminal block 1 is inserted into the mounting groove 23, the pin 22 extends into the wiring through groove 113, the pin 22 abuts against the connecting terminal 12, the buckle 118 passes through the snap-fit ​​hole 25, the buckle 118's claw abuts against the snap-fit ​​block 24, and the snap-fit ​​between the buckle 118 and the snap-fit ​​block 24 helps to improve the stability of the connection between the terminal block 1 and the base 2.

[0035] The connecting terminal 12 is made of metal and includes an integrally formed piercing portion 121 and a connecting portion 122. A piercing groove 1211 is formed at the end of the piercing portion 121 away from the connecting portion 122. The opening size of the piercing groove 1211 gradually increases along the extending direction of the connecting terminal 12. In this embodiment, the piercing groove 1211 is a V-shaped groove. The groove wall of the piercing groove 1211 can cut through the outer insulation layer of the cable. By setting the piercing groove 1211 as a V-shaped groove, not only can the requirement to cut through the outer insulation layer of the cable be met, but the requirement to connect with cables of various diameters can also be met, thus improving the applicability of the piercing connector.

[0036] The connecting terminal 12 also includes a connecting portion 122, which is disposed on one side of the piercing portion 121. The connecting portion 122 includes a first connecting plate 1221, a second connecting plate 1222, and a third connecting plate 1223 connected in sequence. The first connecting plate 1221, the second connecting portion 122, and the third connecting plate 1223 enclose a connecting groove 1224. A first engaging portion 1226 is provided on the first connecting plate 1221, and a second engaging portion 1227 is provided on the second connecting plate 1222. The first engaging portion 1226 and the second engaging portion 1227 define an engaging gap 1225. When the terminal 1 is connected to the base 2, the pin 22 is inserted into the connecting groove 1224 through the engaging gap 1225, and both the first engaging portion 1226 and the second engaging portion 1227 abut against the pin 22. The arrangement of the first engaging part 1226 and the second engaging part 1227 helps to improve the stability of the connection between the pin 22 and the connecting terminal 12, thereby improving the stability of the connection between the terminal 1 and the base 2.

[0037] When the piercing connector is connected to a cable, the cable extends from the corresponding connecting hole 142 into the wiring groove 113. One end of the cable extending into the wiring groove 113 is located between the connecting terminal 12 and the wire clamping member 13. Then, the wire clamping member 13 is pushed, causing the wire clamping post 132 to push the cable towards the connecting terminal 12 until the cable is placed into the piercing groove 1211 and the piercing part 121 cuts through the outer insulation layer of the cable. The piercing part 121 abuts against the conductive core of the cable, and the locking teeth 1331 can engage with the corresponding tooth groove 1141, so that the wire clamping member 13 can press cables of different diameters tightly. Finally, the connecting terminal 1 is inserted into the socket, so that the guide strip 117 can slide and engage with the corresponding guide groove 26, and the buckle 118 engages with the locking block 24, thereby realizing the connection between the piercing connector and the cable.

[0038] This application also provides an air conditioner that includes the piercing connector described above. Since the air conditioner has the aforementioned piercing connector, it possesses at least some or all of the beneficial effects of the piercing connector, which will not be elaborated upon here.
