Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, specifically to a multi-purpose quick-connect connector without stripping. Background Technology
[0002] With the continuous development of society, economy, and technology, people increasingly rely on various electrical appliances for their lives and work. The widespread use of these appliances increases the demand for electricity. Most electrical appliances use low-voltage wires for connection. As is well known, low-voltage wires are used to transmit voltages ranging from 110 to 380 volts. During electrical installation, it is common to connect or branch wires. The most common practice is to twist the conductors together and then seal them with insulating tape. Alternatively, some wire connectors involve stripping the insulation from the wires and then clamping the conductors onto the connector, usually secured with screws. These methods have the following problems: 1. Installers need to disconnect the power, remove the insulation, and wrap the wires, which is very time-consuming; 2. After a period of time, the insulating tape becomes damp or loosened, reducing its adhesiveness and making it prone to falling off and exposing the conductor joints, endangering people's safety.

[0042] Please see Figures 1 to 6This embodiment provides a multi-purpose quick-connector without stripping, including a housing 1, a contact cover 2 and a metal contact 3. The outer walls of three sides of the housing 1 (such as the left outer wall, the front outer wall and the right outer wall) are respectively provided with a first wiring groove 11, a second wiring groove 12 and a third wiring groove 13, and the second wiring groove 12 is perpendicular to the first wiring groove 11 and the third wiring groove 13. The upper surface of the housing 1 is provided with a cover slot 14, and the bottom of the cover slot 14 is provided with a first contact piece slot 15. The first contact piece slot 15 is interconnected with the first wiring groove 11, the second wiring groove 12 and the third wiring groove 13 respectively. The contact piece cover 2 is inserted into the cover slot 14, and the bottom of the contact piece cover 2 is provided with a second contact piece slot 21. The lower part of the hardware contact piece 3 is inserted into the first contact piece slot 15, and the upper part of the hardware contact piece 3 is inserted into the second contact piece slot 21. The lower part of the hardware contact piece 3 is provided with three stripping serrations 31 that extend to the first wiring groove 11, the second wiring groove 12 and the third wiring groove 13 respectively.

Then, initially insert the lower end of the metal contact piece 3 into the first contact piece slot 15 of the housing 1. Finally, insert the contact piece cover 2 into the cover slot 14 of the housing 1. During the insertion of the contact piece cover 2, the upper end of the metal contact piece 3 will be inserted into the second contact piece slot 21 at the bottom of the contact piece cover 2. After the upper end of the metal contact piece 3 is fully inserted into the second contact piece slot 21, as the contact piece cover 2 continues to be inserted, the contact piece cover 2 will fully insert the lower end of the metal contact piece 3 into the first contact piece slot 15 of the housing 1, so that the metal contact piece 3 can pierce the insulation of the wire 4 through the stripping serrations 31, thus achieving the purpose of circuit connection. This operation process is simple and quick, the conductor of the wire 4 will not be exposed, it is safe to use, and the connection is quick.
[0044] The multi-purpose quick-connector without stripping in this embodiment has a first wiring slot 11, a second wiring slot 12, and a third wiring slot 13 on three sides of the housing 1 for inserting power supply wires 4. The second wiring slot 12 is perpendicular to the first wiring slot 11 and the third wiring slot 13. Two horizontal wires 4 can be connected through the first wiring slot 11 and the third wiring slot 13. Two vertical wires 4 can be connected through the first wiring slot 11 / the third wiring slot 13 and the second wiring slot 12. Three wires 4 can also be connected through the first wiring slot 11, the second wiring slot 12 and the third wiring slot 13, so that the three wires 4 are arranged in a "T" shape, which can adapt to the needs of various occasions.
[0045] Please see Figure 7In one embodiment, the left and right sidewalls of the second wiring groove 12 respectively form insertion limiting portions 121 for the first wiring groove 11 and the third wiring groove 13. The insertion limiting portions 121 limit the insertion of the wire 4 into the first wiring groove 11 and the third wiring groove 13. When the wire 4 is inserted into the first wiring groove 11 or the third wiring groove 13, the sidewalls of the second wiring groove 12 restrict the insertion position of the wire 4, preventing over-insertion and ensuring the accuracy and consistency of the wire 4's insertion position. This allows the stripping serrations 31 on the metal contact piece 3 to accurately pierce the insulation of the wire 4, ensuring effective contact between the wire 4 and the metal contact piece 3, improving the stability and reliability of the circuit connection. Simultaneously, it also facilitates the user in accurately inserting the wire 4 into the appropriate position, making the operation more standardized and convenient.
[0046] In one embodiment, a plurality of first wiring slots 11, second wiring slots 12, and third wiring slots 13 are respectively formed on three of the outer walls of the housing 1, arranged side by side. The number of first wiring slots 11, second wiring slots 12, third wiring slots 13, metal contact pieces 3, first contact piece slots 15, and second contact piece slots 21 are the same. The positions of the first wiring slots 11 and second wiring slots 12 correspond one-to-one with the positions of the first contact piece slots 15, second contact piece slots 21, and metal contact pieces 3, and the stripping serrations 31 on the center of each metal contact piece 3 extend to the corresponding second wiring slot 12. This arrangement allows the connector to handle the connection of multiple wires 4 simultaneously, greatly improving work efficiency through parallel processing. It should be noted that this invention does not limit the number of first wiring slots 11, second wiring slots 12, third wiring slots 13, metal contact pieces 3, first contact piece slots 15, and second contact piece slots 21. Those skilled in the art can set the required number according to actual conditions, such as 1, 2, 3, 4, 5, 6, or more. Figure 4 , Figures 8 to 12 As shown.
