[0002] Power distribution products are widely used in all power distribution fields, including data centers, industry, nuclear power, and subways, with drawer cabinets being a major product among them. With the development of drawer cabinets, especially the continuous enhancement of their functions, secondary connectors for drawer cabinets typically refer to modular plug-in components used for secondary circuit connections in electrical equipment (such as switchgear and distribution cabinets). These are mainly used for rapid connections in low-voltage, low-current circuits such as signal, control, and measurement circuits.

[0003] Existing secondary connectors typically use screw-based wiring when connecting cables. This method requires the use of auxiliary tools (screwdrivers) to connect and disconnect the wires, making the wiring process cumbersome, time-consuming, and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a secondary connector that allows for quick connection and disconnection.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A secondary connector for quick connection and disconnection includes a housing, a handle rotatably mounted on the housing, and a contact piece and a spring piece disposed within the housing. The spring piece engages with the contact piece and has a through hole for the cable to pass through. The contact piece has a contact portion that is inserted into the through hole. The handle rotates relative to the housing to have a first position and a second position. When the handle is in the first position, the spring piece abuts against the handle under the action of elasticity. When the handle rotates from the first position to the second position, the rotational force of the handle causes the spring piece to deform, thereby forming a wiring space between the through hole and the contact portion of the spring piece for the cable to be inserted or withdrawn.

[0006] In some embodiments, the spring includes a support portion, a bending portion, and a threading portion. The support portion, the bending portion, and the threading portion are integrally formed, and a positioning space is formed between the support portion, the bending portion, and the threading portion. The threading hole is provided on the threading portion. The support portion abuts against the upper end surface of the contact portion. The lower end surface of the contact portion has a wiring contact surface that contacts the cable. The support portion has a locking portion that is inserted into the threading hole.

[0007] In some embodiments, a positioning post is provided in the housing at the corresponding positioning space, the positioning post is inserted into the positioning space, and a snap-fit ​​space is formed between the positioning post and the contact part, and the support part is snapped into the snap-fit ​​space.

[0008] In some embodiments, a limiting post is provided on one side of the housing corresponding to the positioning post, and a limiting space is formed between the positioning post and the limiting post. The bending portion has a first bending portion that passes through the limiting space.

[0009] In some embodiments, one end of the handle has a cam portion that cooperates with the bending portion, and the bending portion has a second bending portion that abuts against the cam portion.

[0010] In some embodiments, the cam portion is provided with a positioning hole, and the housing is provided with a positioning shaft that mates with the positioning hole. The positioning shaft passes through the positioning hole and forms a rotatable connection between the handle and the positioning shaft.

[0011] In some embodiments, the other end of the handle has a handle portion extending outside the housing, and the handle portion has a plurality of anti-slip grooves distributed thereon.

[0012] In some embodiments, the housing is provided with a receiving groove that mates with the handle portion, and when the handle is rotated to the first position, the handle portion is engaged in the receiving groove.

[0013] In some embodiments, the handle portion has two positioning protrusions on both sides, and the receiving groove is provided with two positioning grooves that cooperate with the two positioning protrusions. When the handle is rotated to the first position, the two positioning protrusions are engaged in the two positioning grooves.

[0014] In some embodiments, the contact portion has a guide limiting portion that mates with a wire hole, the guide limiting portion passing through the wire hole and engaging in a positioning groove in the housing.

[0015] The beneficial effects of this utility model are as follows: This secondary connector uses a plug-in connection method. By rotating the handle, the spring is driven to deform, and the wire hole of the spring presses the cable tightly onto the contact part of the contact piece, effectively increasing the cable pull-out force and ensuring a more reliable and secure contact between the cable and the contact part. By driving the spring to deform through the handle, the cable can be inserted into or pulled out of the wiring space, making connection and disconnection more convenient. When wiring, rotating the handle from the first position to the second position causes the spring to deform, creating a wiring space between the wire hole of the spring and the contact part. The cable is then passed through the wire hole and inserted into the wiring space. Then, rotating the handle from the second position to the first position causes the spring to press the cable tightly onto the wiring contact surface on the lower end face of the contact part under the action of the spring's elastic force, thus completing the wiring. When disconnecting the wire, rotate the handle from the first position to the second position. The rotation force of the handle drives the spring to deform, and a wiring space is formed between the wire hole and the contact part of the spring. Then, pull the cable out of the wiring space and the wire hole to complete the disconnection. Attached Figure Description

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0026] like Figure 1 and 2As shown, a quick-connect and disconnect secondary connector includes a housing 1, a handle 2 rotatably mounted on the housing 1, a contact piece 3 and a spring piece 4 disposed within the housing 1. The spring piece 4 engages with the contact piece 3 and has a through hole 40 for cables to pass through. The contact piece 3 has a contact portion 31 that inserts into the through hole 40. The handle 2 rotates relative to the housing 1 to have a first position and a second position. When the handle 2 is in the first position, the spring piece 4 abuts against the handle 2 under the action of elastic force. When the handle 2 rotates from the first position to the second position, the rotational force of the handle 2 causes the spring piece 4 to deform, forming a wiring space 300 between the through hole 40 and the contact portion 31 for cables to be inserted or removed. A wiring hole 10 for cables to pass through is provided on the housing 1 at the corresponding location of the wiring space 300. This secondary connector uses a plug-in connection method. By rotating the handle, the spring is driven to deform, and the wire hole of the spring presses the cable tightly onto the contact part of the contact piece, effectively increasing the cable pull-out force and ensuring a more reliable and firm contact between the cable and the contact part. By driving the spring to deform through the handle, the cable can be inserted or pulled out of the wiring space, making it more convenient to connect and disconnect the wires.

[0027] like Figure 2 , 5 As shown, the spring 4 includes a support portion 41, a bending portion 42, and a threading portion 43. The support portion 41, the bending portion 42, and the threading portion 43 are integrally formed, and a positioning space 400 is formed between the support portion 41, the bending portion 42, and the threading portion 43. A threading hole 40 is provided on the threading portion 43. The support portion 41 abuts against the upper end surface of the contact portion 31, and the lower end surface of the contact portion 31 has a wiring contact surface 311 for contacting the cable. The support portion 41 has a locking portion 411 that inserts into the threading hole 40. The support portion of the spring abuts against the contact portion of the contact piece, thereby facilitating the assembly of the spring and the contact piece, making assembly more convenient.

[0028] like Figure 2 and 4As shown, a positioning post 11 is provided inside the housing 1 at a corresponding positioning space 400. The positioning post 11 passes through the positioning space 400, and a snap-fit ​​space 110 is formed between the positioning post 11 and the contact part 31. The support part 41 is engaged in the snap-fit ​​space 110. The positioning post plays a positioning role for the spring piece, thereby facilitating the assembly of the spring piece and the housing. The support part is engaged in the snap-fit ​​space, thereby ensuring a tighter connection between the spring piece, the housing, and the contact piece. A limiting post 12 is provided on one side of the housing 1 corresponding to the positioning post 11. A limiting space 120 is formed between the positioning post 11 and the limiting post 12. The bending part 42 has a first bending part 421 that passes through the limiting space 120. The first bending part of the bending part is engaged between the positioning post and the limiting post, thereby facilitating the assembly of the spring piece and the housing and improving assembly efficiency. One end of the handle 2 has a cam part 21 that cooperates with the bending part 42. The bending part 42 has a second bending part 422 that abuts against the cam part 21. The handle, driven by a cam, deforms the bent portion of the spring, ensuring more reliable transmission between the handle and the spring. A positioning hole 211 is provided on the cam portion 21, and a positioning shaft 13, which mates with the positioning hole 211, is provided inside the housing 1. The positioning shaft 13 passes through the positioning hole 211, forming a rotatable connection between the handle 2 and the positioning shaft 13. The handle is rotatably mounted on the positioning shaft of the housing via the cam portion, facilitating assembly between the handle and the housing and ensuring reliable rotation of the handle within the housing. The other end of the handle 2 has a handle portion 22 extending outside the housing 1, with multiple anti-slip grooves 221 distributed on the handle portion 22. These anti-slip grooves provide anti-slip properties, facilitating handle movement during wiring and making operation more convenient. A receiving groove 14 is provided on the housing 1 to mate with the handle portion 22. When the handle 2 is rotated to the first position, the handle portion 22 engages within the receiving groove 14. The receiving groove on the housing accommodates the handle portion, which is placed within it, providing positioning and enhancing the aesthetics of the design. The handle 22 has two positioning protrusions 222 on both sides, and two positioning grooves 141 are provided in the receiving groove 14 to cooperate with the two positioning protrusions 222. When the handle 2 is rotated to the first position, the two positioning protrusions 222 are engaged in the two positioning grooves 141. The handle is engaged in the positioning grooves in the receiving groove by the positioning protrusions, and the positioning grooves can position the handle in the first position, which can ensure a tighter connection between the handle and the housing.

[0029] like Figure 2 and 3 As shown, the contact portion 31 has a guide and limiting portion 312 that mates with the wire hole 40. The guide and limiting portion 312 passes through the wire hole 40 and engages within the positioning groove 15 of the housing 1. The contact portion is engaged within the wire hole by the guide and limiting portion, thereby facilitating the assembly of the contact piece and the spring piece.

[0030] When wiring, rotate the handle from the first position to the second position. The rotation of the handle causes the spring to deform, creating a wiring space between the wire hole and the contact part. Pass the cable through the wire hole and insert it into the wiring space. Then rotate the handle from the second position to the first position. Under the action of the spring's elasticity, the wire hole presses the cable firmly against the wiring contact surface on the lower end of the contact part, thus completing the wiring. When disconnecting, rotate the handle from the first position to the second position. The rotation of the handle causes the spring to deform, creating a wiring space between the wire hole and the contact part. Pull the cable out of the wiring space and the wire hole to complete the disconnection.

[0031] The above description is only one embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model; the scope of protection of the present utility model is defined by the claims in the claims, and all equivalent changes and modifications made in accordance with the utility model are within the scope of protection of the present utility model patent.
