Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a convenient quick connector. Background Technology

[0002] In the field of electrical connections, connectors, as a key electrical connection component, are widely used in various electronic devices and power systems to achieve reliable connections between different circuits. However, traditional connectors have many shortcomings in design and use. Traditional connectors often require complex installation tools and involve cumbersome installation steps, which not only increases installation time and cost but also demands high levels of expertise from operators. Furthermore, the components of traditional connectors are mostly modular, making them prone to misalignment during assembly, leading to a decline in overall connector performance. Additionally, traditional connectors struggle to effectively isolate conductive materials that may be present in the piercing section from the base, increasing the risk of electrical short circuits and posing a serious threat to the safe operation of equipment. Moreover, after installation, operators cannot visually observe the working status of the piercing section, such as whether it accurately pierces the insulated conductor and whether the piercing depth is appropriate, which greatly inconveniences equipment debugging and maintenance. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a convenient quick connector that is simple in structure, easy to install, reliable in sealing, has good insulation performance, and is easy to observe the puncture state.

[0004] To achieve the above objectives, this utility model employs a convenient quick connector, comprising a housing, an outer shell, a base, and a cap. One end of the outer shell is inserted into the cap via an interference fit, and one end of the base is inserted into the other end of the outer shell via a clearance fit. A piercing body is provided inside the outer shell, comprising a shaft portion and a piercing portion, which are integrally formed. A sealing ring is installed on the shaft portion of the piercing body at the interference fit point with the cap and the outer shell. One end of the sealing ring is located inside the outer shell, and the other end is located inside the cap. Segmented claws completely cover the outer wall of the sealing ring. An insulating pad is wrapped around the piercing portion. A needle is formed at the end of the piercing portion near the base, and the needle penetrates the insulating pad and extends into the base.

[0005] The advantages of the above structure are as follows: By using an interference fit between the outer shell and the cap, and a clearance fit between the base and the outer shell, the connector can be quickly assembled without the need for complex tools. The shaft, piercing part, and needle of the piercing body are integrally molded, reducing the number of component assembly steps and effectively avoiding connection loosening problems that may be caused by improper assembly. A sealing ring is installed at the interference fit between the shaft of the piercing body and the cap and the outer shell. Its outer wall is fully wrapped with segmented claws. The segmented claws form a tight fit with the inner wall of the outer shell and the cap through elastic deformation, effectively preventing external dust, moisture and other impurities from entering the connector. The piercing part of the piercing body is covered with an insulating pad. The needle passes through the insulating pad and extends into the base. The insulating pad can isolate the piercing part from any conductive materials that may exist in the base, effectively preventing electrical short circuits and other faults.

[0006] This utility model further features segmented claws that are annular in shape, with their inner diameter matching the outer diameter of the sealing ring. By ensuring the segmented claws are annular and their inner diameter matches the outer diameter of the sealing ring, they can fit tightly and evenly against the outer wall of the sealing ring. When the connector is subjected to external vibrations, impacts, or temperature changes, the segmented claws can effectively limit the displacement of the sealing ring, preventing sealing failure due to loosening.

[0007] This utility model is further configured with a slot on the side wall of the base, the slot being tapered in shape. The tapered slot, wider at the top and narrower at the bottom, provides the operator with a wide field of view. During connector installation or use, the operator does not need to disassemble the connector; they can simply observe from the side through the slot whether the piercing part accurately pierces the conductor of the insulated wire, and whether the piercing depth is appropriate.

[0008] This utility model is further configured such that the housing, base, cap, and segmented claws are all made of plastic. By using plastic for the housing, base, cap, and segmented claws, a reliable insulation barrier can be formed between the internal electrical components of the connector and the external environment, avoiding electrical accidents caused by leakage and ensuring the safety of operators and the normal operation of equipment.

[0011] Figure 3 This is a schematic diagram of the puncture body structure according to an embodiment of the present invention. Detailed Implementation

[0012] like Figures 1-3As shown, an embodiment of this utility model provides a convenient quick connector, including a housing 1. The housing 1 consists of three parts: an outer shell 11, a base 12, and a cap 13. One end of the outer shell 11 is tightly inserted into the cap 13 through an interference fit, which ensures the reliability of the connection. One end of the base 12 is inserted into the other end of the outer shell 11 through a clearance fit, which facilitates installation and disassembly.

[0013] The housing 11 contains a piercing body 2, which consists of a shaft portion 21 and a piercing portion 22, and is a one-piece molded structure, reducing assembly steps and improving the overall performance of the connector. A sealing ring 3 is installed on the shaft portion 21 of the piercing body 2 at the interference fit between it and the cap 13 and the housing 11. One end of the sealing ring 3 is located inside the housing 11, and the other end is located inside the cap 13, effectively preventing external impurities from entering the connector. Simultaneously, the outer wall of the sealing ring 3 is fully enclosed by segmented claws 4, which are annular in shape, and their inner diameter matches the outer diameter of the sealing ring 3. To ensure that the sealing ring 3 is not easily displaced when subjected to external force, the puncture part 22 of the puncture body 2 is wrapped with an insulating pad 5. A needle 221 is formed at one end of the puncture part 22 located on the base 12. The needle 221 passes through the insulating pad 5 and extends into the base 12, effectively isolating the puncture part 22 from any conductive materials that may exist in the base 12, preventing electrical short circuits. Conical slots 6 are provided on both sides of the base 12. The design of the slots 6 provides the operator with a wide field of view, making it easy to observe the working status of the puncture part 22.

[0014] In addition, the outer shell 11, base 12, cap 13 and segmented claw 4 are all made of plastic, which has good insulation performance, ensuring that a reliable insulation barrier is formed between the internal electrical components of the connector and the external environment, thus protecting the life safety of operators and the normal operation of the equipment.

[0015] This connector is mainly used for piercing insulated wires of 1kV and below without stripping, which greatly improves construction efficiency and safety.

[0016] Of course, in addition to the above embodiments, this utility model may have other various embodiments. Without departing from the essential technical solution of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, and these changes or modifications are equivalent to the technical solution in this patent. Therefore, these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model, and the utility model creation is in line with the applicant's actual R&D capabilities and resource conditions.
