[0002] In related technologies, two-pole plugs are common electrical connection accessories. Existing two-pole plugs usually consist of three parts: a shell, pins, and terminals. The two pins are arranged parallel to each other in the shell and are electrically connected to the circuit through the terminals. However, the pin structure of traditional two-pole plugs generally adopts a symmetrical design, which means that the two pins need to be manufactured separately using independent molds. This not only increases the manufacturing cost but also adds an extra assembly process for the pins, which is not conducive to reducing production costs. Utility Model Content

[0026] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0027] Understandably, referring to Figures 1 to 5The two-pole plug of this utility model includes a housing 100 and two pins 200. The housing 100 is provided with two mounting slots 110, which are symmetrically arranged inside the housing 100. A terminal block 120 is provided in the mounting slot 110 for accommodating wires. The two pins 200 are respectively arranged in the two mounting slots 110 and pass through the housing 100. One end of the pin 200 is provided with a bent portion 210, which extends away from the side of the pin 200. Along the width direction of the pin 200, the bent portion 210 is located in the middle of the pin 200. The bent portion 210 is inserted into the terminal block 120, and the terminal block 120 is threadedly connected to a first fastener 130.

[0028] The housing 100 has two mounting slots 110, which are symmetrically arranged within the housing 100. Terminal blocks 120 are arranged within the mounting slots 110, and wires pass through the terminal blocks 120. Two pins 200 are both inserted within the housing 100. A bend 210 is located at one end of each pin 200 and extends away from the pin 200. By positioning the bend 210 at the midpoint of the pin 200's width, when the two pins 200 are symmetrically arranged, the two bends 210 are symmetrically positioned within the two terminal blocks 120. By driving the first fastener 130 to rotate, the terminal blocks 120 can bring the wires to abut against the bends 210, making the structures of the two pins 200 identical. This eliminates the need to manufacture two separate pins 200, simplifies the assembly process, and helps reduce production costs.

[0029] It should be noted that the bent portion 210 is located in the middle of the width direction of the pin 200. By setting the bent portion 210 to extend away from the pin 200, not only can the two pins 200 be symmetrically arranged in the two mounting slots 110, but the structures of the two pins 200 are also completely identical, which can improve the versatility of the pins 200, reduce the inventory accumulation of pins 200, and help reduce processing costs.

[0030] The pin 200 and the bent portion 210 are integrally formed. The bent portion 210 can be formed in the pin 200 by bending, which not only helps to reduce processing costs, but also enhances the structural strength of the pin 200, reduces the possibility of breakage between the bent portion 210 and the pin 200, and improves reliability.

[0031] In addition, the first fastener 130 can be a bolt, screw, etc., which will not be described in detail here. By driving the first fastener 130 to rotate, the first fastener 130 causes the terminal 120 to slide in the mounting groove 110, so that the terminal 120 can drive the wire to abut against the bending part 210, and can press the wire tightly on the bending part 210, so that the connection between the plug 200 and the wire is stable and the electrical stability is improved.

[0032] Understandably, referring to Figure 3 and Figure 5 Multiple grooves 211 are provided on both opposite sides of the bent portion 210, and the grooves 211 are arranged at intervals. By providing multiple spaced grooves 211 on both opposite sides of the bent portion 210, when the first fastener 130 drives the terminal 120 to bring the wire into contact with the bent portion 210, the grooves 211 can increase the friction between the bent portion 210 and the wire, making the connection between the wire and the bent portion 210 more stable, improving the stability of the connection between the plug 200 and the wire, and enhancing the reliability of the electrical connection.

[0033] In addition, by providing multiple grooves 211 on the bending portion 210, the surface area of ​​the bending portion 210 can be increased, which helps to dissipate heat during electrical connection, reduces the risk of the connection part being too hot due to the heat generated by the current passing through, which may affect the electrical performance or even cause damage, and improves the reliability of the two-pole plug.

[0034] It should be noted that by providing grooves 211 on both opposite sides of the bent portion 210, when the pins 200 are symmetrically arranged in the two mounting slots 110, the wires can abut against the end face of the grooves 211, thereby improving the versatility of the pins 200.

[0035] Understandably, referring to Figures 3 to 5 The housing 100 is provided with a limiting seat 140, which is spaced apart from the mounting groove 110. A limiting block 212 protrudes from the side of the bent portion 210 away from the pin 200, and the limiting block 212 is arranged between the limiting seat 140 and the mounting groove 110. The limiting seat 140 and the mounting groove 110 are arranged at intervals, and the limiting block 212 is located on the side of the bent portion 210 away from the pin 200. By arranging the limiting block 212 between the limiting seat 140 and the mounting groove 110, the position of the pin 200 can be easily limited, making it easier for the pin 200 to be accurately installed into the mounting groove 110, preventing the pin 200 from shifting during installation or use, and improving the accuracy of installation.

[0036] In addition, during use, when the two-pole plug is subjected to external force, the limiting block 212 can abut against the outer wall of the limiting seat 140 or the mounting groove 110, thereby restricting the movement or shaking of the pin 200, enhancing the stability of the connection between the pin 200 and the housing 100, effectively reducing the probability of electrical faults such as poor contact caused by loose pin 200, and improving the reliability of the two-pole plug.

[0037] Understandably, referring to Figure 1 and Figure 3 An insulating sleeve 220 is fitted over the middle of the plug 200, extending into the housing 100. The insulating sleeve 220, located in the middle of the plug 200 and extending into the housing 100, effectively encloses the plug 200, reducing the possibility of electric shock due to accidental contact between the user and the plug 200, thus lowering the risk of electric shock and improving safety.

[0038] In addition, the insulating sleeve 220 extends into the housing 100 so that the insulating sleeve 220 can absorb the gap between the pin 200 and the housing 100, improve the sealing between the pin 200 and the housing 100, reduce the possibility of impurities entering the housing 100, and improve reliability.

[0039] It should be noted that the insulating sleeve 220 can be made of rubber, silicone, or other insulating materials, which will not be elaborated here.

[0040] Understandably, referring to Figure 1 and Figure 3 A connecting groove 213 is provided in the middle of the plug 200. The connecting groove 213 is arranged circumferentially around the plug 200, and the insulating sleeve 220 is arranged in the connecting groove 213. The connecting groove 213 is arranged in the middle of the plug 200. By arranging the insulating sleeve 220 in the connecting groove 213, the insulating sleeve 220 can be stably placed in the plug 200, making the connection between the insulating sleeve 220 and the plug 200 tight and reliable. This effectively prevents the insulating sleeve 220 from loosening or falling off due to frequent insertion and removal of the plug 200 or external pulling during use, and improves the stability of the connection.

[0041] Understandably, referring to Figure 2 and Figure 3The housing 100 includes a first outer shell 161 and a second outer shell 162. A mounting groove 110 is arranged on the first outer shell 161. The first outer shell 161 and the second outer shell 162 are fastened together. A second fastener passes through the second outer shell 162 and is threadedly connected to the first outer shell 161. The fastening of the first outer shell 161 and the second outer shell 162, and the threaded connection between the second fastener and the first outer shell 161, allows the first outer shell 161 and the second outer shell 162 to be fixed together. This facilitates the manufacturing of the housing 100, reduces manufacturing costs, and facilitates the assembly of the two-pole plug, shortening assembly time and reducing manufacturing costs.

[0042] It should be noted that the second fastener can be a bolt, screw, etc., which will not be elaborated here.

[0043] Specifically, refer to Figure 1 and Figure 3 The housing 100 is connected to a connector 150, which is connected to a mounting groove 110. A first fastener 130 passes through the connector 150. The connector 150 is connected to the mounting groove 110, and the first fastener 130 passes through the connector 150 to lock the connector 150 onto the mounting groove 110, reducing the possibility of the connector 150 loosening. This allows the connector 150 to close the mounting groove 110, reducing the possibility of the terminal block 120 and the bend 210 loosening, and improving the stability of the connection.

[0044] Specifically, refer to Figures 2 to 4 The first outer shell 161 is provided with a positioning groove 163, and the connector 150 is provided with a positioning block 151, which passes through the positioning groove 163. The positioning block 151, by passing through the positioning groove 163, allows the connector 150 to be easily positioned on the first outer shell 161, improves the positional stability of the connector 150, reduces the possibility of loosening or shifting, and enhances the structural stability of the two-pole plug.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
