Description

Technical Field

[0001] This invention relates to a connector, and more particularly to a connector for connecting electrical conductors. Background Technology

[0002] Conventional connectors for connecting electrical conductors consist of a spring with one end fixedly positioned to a conductive terminal or insulating body, and the other end forming a cantilever structure that engages with the conductive contact surface of the conductive terminal to clamp and conduct wires inserted through the wiring hole. When connecting or disconnecting wires, external tools or handles are needed to press the spring to deform and loosen the wires. Because the spring has an automatic elastic reset capability, it is necessary to hold down the external tool or handle while connecting the wires, making connection and disconnection inconvenient, time-consuming, and hindering construction efficiency. Summary of the Invention

[0003] To overcome the above-mentioned defects, the present invention provides a connector for connecting electrical conductors, which enables one-handed connection and retraction, and has a simple structure and is easy to operate.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: A connector for connecting electrical conductors includes an insulating body, a conductive terminal, a spring, and a handle. The insulating body has an internal cavity, and a wire inlet hole for inserting a wire is provided on the side wall of the insulating body. The wire inlet hole communicates with the cavity. One end of the conductive terminal has a conductive contact surface, which is fixedly disposed within the cavity of the insulating body. One end of the spring is fixed within the cavity, and the other end of the spring forms a cantilever structure capable of elastically swinging. A wire clamping arm is provided at the other end of the spring. The wire clamping arm and the conductive contact surface of the conductive terminal together form a wire clamping structure capable of clamping the wire. The handle is rotatable. The other end of the spring flap swings elastically to open the wire clamping structure. A fixed locking point is fixedly provided in the receiving cavity of the insulating body. A fixed buckle is also provided on the other end of the spring flap. The fixed buckle can engage with the fixed locking point and be positioned when the wire clamping structure is opened, as the other end of the spring flap swings elastically. A release mechanism is also provided in the receiving cavity of the insulating body. A trigger device is provided on one end of the release mechanism, and a prying device is provided on the other end of the release mechanism. A wire inserted into the receiving cavity to a set depth through the wire inlet hole can trigger the trigger device of the release mechanism. The trigger device can drive the prying device to reciprocate, thereby prying the fixed buckle off the fixed locking point and disengaging the fixed locking point from the fixed buckle.

[0005] As a further improvement of the present invention, a snap-fit ​​connecting arm that can be elastically deformed is formed on the other side wall of the spring piece by tearing and bending. The fixing buckle is a slot located on the snap-fit ​​connecting arm, and the fixing point is a hook corresponding to the fixing buckle. The reciprocating motion of the prying device can push the snap-fit ​​connecting arm to deform so that the slot on it disengages from the hook of the fixing point.

[0006] As a further improvement of the present invention, the fixing point also includes a positioning arm. One end of the positioning arm is fixedly disposed in the receiving cavity of the insulating body, and the hook is integrally formed on the other end of the positioning arm. The prying device is sleeved on the outside of the positioning arm of the fixing point. The prying device can slide back and forth along the extension direction of the positioning arm. The prying device can press against the connecting arm and slide towards the other end of the positioning arm to disengage from the hook on the positioning arm.

[0007] As a further improvement of the present invention, the positioning arm is an elastic cantilever structure integrally formed on one end of the spring sheet by tearing and bending, and the other end of the positioning arm is a free end.

[0008] As a further improvement of the present invention, the spring sheet has a V-shaped structure, and the bend of the V-shaped spring sheet has an arc structure. The fastening connecting arm and the positioning arm are integrally formed on the two side walls of the V-shaped spring sheet. A limiting wall is fixedly provided in the receiving cavity of the insulating body. A limiting channel is formed between the limiting wall and the inner wall of the receiving cavity. One side wall of the V-shaped spring sheet is stopped and clamped in the limiting channel. One end of the limiting wall forms an arc support surface. The bend of the V-shaped spring sheet can be elastically deformed and sleeved on the outer side of the arc support surface. A hollow part is formed on the limiting wall. The free end of the positioning arm can swing and is inserted into the hollow part. The two sides of the free end of the positioning arm are stopped on the inner wall of the hollow part.

[0009] As a further improvement of the present invention, the triggering device and the prying device of the release mechanism are integrally formed seesaw structures. One end of the seesaw structure forms the triggering device, and the other end forms the prying device. The triggering device stops on the feed path of the wire inserted into the receiving cavity through the wire inlet hole. The end of the wire inserted into the receiving cavity to a set depth through the wire inlet hole can press tightly against the surface of the triggering device. The prying device has a notch structure, which is sleeved on the outside of the positioning arm. The release mechanism also includes an elastic reset member, which can provide the seesaw structure with an elastic reset force to maintain it at a specified angle.

[0010] As a further improvement of the present invention, the elastic reset member is an elastic cantilever structure installed on the inner side wall of the receiving cavity of the insulating body, the triggering device is integrally formed on the free end of the elastic reset member, and the prying device is formed by tearing and bending the side wall of the elastic reset member.

[0011] As a further improvement of the present invention, the root of the elastic reset member is formed into a T-shaped positioning part by tearing and bending in the opposite direction, and a T-shaped positioning groove is also provided in the receiving cavity of the insulating body, and the T-shaped positioning part of the root of the elastic reset member is stopped and inserted into the T-shaped positioning groove.

[0012] As a further improvement of the present invention, the insulating body is provided with a handle slide that communicates with the receiving cavity. The handle is inserted into the handle slide that can slide back and forth a set distance. One end of the handle extends out of the outside of the insulating body to form an operating end, and the other end of the handle extends into the receiving cavity, and the other end of the handle forms an arc-shaped contact surface that can tightly abut against the other end of the spring piece.

[0013] As a further improvement of the present invention, the insulating body includes a plastic body and a plastic cover. The conductive terminal includes a first conductive sheet with a U-shaped structure and a second conductive sheet with a U-shaped structure. The conductive contact surface is located on both side walls of the U-shaped structure of the first conductive sheet. The plastic body has two spaced-apart slots with a connecting channel between them. The wire inlet and the handle slide are both located on the plastic body, and the wire inlet and the handle slide are respectively connected to the slots on the plastic body. A first conductive sheet slot is provided on the side wall of the slot with the wire inlet of the plastic body, and a second conductive sheet slot is provided on the side wall of the slot parallel to the axis of the wire inlet of the plastic body. The two ends of the first conductive sheet are respectively inserted into the two first conductive sheet slots, and the bottom of the U-shaped structure of the first conductive sheet is tightly inserted into the... Within the channel between the two opening slots on the plastic body, the outer surfaces of the two side walls of the first conductive sheet U-shaped structure are tightly abutted against the inner side walls of the two opening slots having second conductive sheet slots. The two side walls of the second conductive sheet U-shaped structure are respectively inserted into the channel formed between the side walls of the first conductive sheet U-shaped structure and the second conductive slot and the limiting channel. A T-shaped limiting protrusion is also provided in the limiting channel. A T-shaped notch is provided on one side wall of the second conductive sheet U-shaped structure. The T-shaped notch of the second conductive sheet is sleeved on the outside of the T-shaped limiting protrusion. The plastic cover is fastened to the plastic body and covers the surface of the opening slot of the plastic body. The plastic cover and the opening slot of the plastic body together form a receiving cavity. The first conductive sheet and the second conductive sheet are tightly sandwiched between the bottom surface of the opening slot of the plastic cover and the plastic body.

[0014] The beneficial effects of this invention are as follows: By setting a fixed locking point inside the insulating body and a fixed buckle on the other end of the spring piece, when the spring piece deforms and opens the wire clamping structure, the fixed buckle on it engages with the fixed locking point for positioning, keeping the other end of the spring piece in the open wire clamping structure state. This facilitates one-handed operation for wiring and wire removal by construction personnel. When the wire is inserted to a certain depth, the wire triggers the release mechanism, which in turn causes the release mechanism's prying device to pry the fixed buckle off the fixed locking point, releasing and resetting the spring piece, clamping the wire, ensuring the wire insertion depth, and ensuring the effective clamping and conduction of the wire by the wire clamping structure. This avoids situations where insufficient wire insertion depth leads to poor conduction signal or unstable clamping and detachment. The overall structure of this invention is simple, easy to assemble, and has low manufacturing cost. Attached Figure Description

[0030] Example: A connector for connecting electrical conductors includes an insulating body, conductive terminals, a spring contact 3, and a handle 4. The insulating body has an internal cavity, and an inlet hole 12 for inserting a wire 5 is provided on its side wall. The inlet hole 12 communicates with the cavity. One end of the conductive terminal has a conductive contact surface 21, which is fixedly disposed within the cavity of the insulating body. One end of the spring contact 3 is fixed within the cavity, and the other end of the spring contact 3 forms a cantilever structure capable of elastically swinging. A clamping arm 31 is provided on the other end of the spring contact 3. The clamping arm 31 and the conductive contact surface 21 of the conductive terminal together form a clamping structure capable of clamping the wire 5. The handle 4 can drive the other end of the spring contact 3 to swing elastically. The wire clamping structure is characterized by the following features: a fixed locking point is fixedly provided in the receiving cavity of the insulating body, and a fixed buckle is also provided on the other end of the spring piece 3. The fixed buckle can be engaged and positioned with the fixed locking point when the wire clamping structure is opened by elastically swinging the other end of the spring piece 3. A release mechanism 6 is also provided in the receiving cavity of the insulating body. A triggering device 61 is provided on one end of the release mechanism 6, and a prying device 62 is provided on the other end of the release mechanism 6. A wire 5 inserted into the receiving cavity at a set depth through the wire inlet hole 12 can trigger the triggering device 61 of the release mechanism 6. The triggering device 61 can move in conjunction with the prying device 62 to reciprocate and thus pry the fixed buckle off the fixed locking point, causing the fixed locking point to disengage from the fixed buckle.

[0031] In the initial state: the clamping arm 31 is pressed against the conductive contact surface 21 of the conductive terminal, and the fixing buckle on the other end of the spring 3 is in the disengaged state from the fixing point in the receiving cavity;

[0032] When wiring, first use the handle 4 to press against the other end of the spring 3 to make it elastically deform. The clamping arm 31 gradually moves away from the conductive contact surface 21 of the conductive terminal. When the distance between the clamping arm 31 and the conductive contact surface 21 of the conductive terminal is greater than the diameter of the wire 5, the fixing buckle on the other end of the spring 3 just engages with the fixing point in the receiving cavity. At this time, release the handle 4, and the other end of the spring 3 remains in this stable state, thereby keeping the clamping arm 31 and the conductive contact surface 21 of the conductive terminal in an open state. After the wire 5 is inserted into the receiving cavity to a certain depth through the inlet hole 12, the wire 5 just triggers the triggering device 61 of the release mechanism 6. At the same time, the triggering device 61 drives the prying device 62 to reciprocate, thereby prying the fixing buckle off the fixing point and disengaging the fixing point from the fixing buckle. The clamping arm 31 at the other end of the spring 3 moves back to the initial state under the action of the elastic restoring force. At this time, the clamping arm 31 of the spring 3 and the conductive contact surface 21 together clamp the wire 5 and conduct it. In order to prevent the clamping arm 31 of the spring 3 from deforming in the direction of the inlet hole 12 when the wire 5 is subjected to tension in the clamping state, which would cause the clamping to fail, it is best to set a serrated structure on the conductive contact surface 21 of the conductive terminal to prevent the clamping arm 31 from deforming in the direction of the inlet hole 12.

[0033] When it is necessary to disconnect the wire, first use the handle 4 to drive the other end of the spring 3 to elastically deform and loosen the wire 5. When the clamping arm 31 of the spring 3 reaches the state of completely loosening the wire 5, the fixing buckle on the other end of the spring 3 just engages with the fixing point in the receiving cavity. At this time, the wire 5 can be kept loose, and the wire 5 can be pulled out from the wiring cavity with one hand.

[0034] The above structure eliminates the need for constant force on the handle 4 when connecting and disconnecting the wire 5. The connection and disconnection of the wire 5 can be achieved with one hand, making the connection and disconnection operations convenient and quick, which helps to improve construction efficiency. Moreover, when connecting the wire, the triggering device 61 of the release mechanism 6 will only be triggered after the wire 5 is inserted to the required depth, so that the spring 3 will automatically release and clamp the wire 5, thereby ensuring the insertion depth of the wire 5 and preventing the clamping arm 31 of the spring 3 from failing to clamp the wire 5 due to insufficient insertion depth.

[0035] On the other side wall of the spring piece 3, a snap-fit ​​connecting arm 32 that can be elastically deformed is formed by tearing and bending. The fixing buckle is a slot 321 located on the snap-fit ​​connecting arm 32, and the fixing point is a hook 331 corresponding to the fixing buckle. The reciprocating motion of the prying device 62 can push the snap-fit ​​connecting arm 32 to deform, causing the slot 321 on it to disengage from the hook 331 of the fixing point.

[0036] Of course, the slot 321 on the connecting arm 32 can also be replaced with a hook 331. The fixing point adopts the slot 321 structure. This is an equivalent replacement structure that can be easily conceived by those skilled in the art based on this application, and it falls within the protection scope of this application. When the other end of the spring 3 is subjected to pressure from the handle 4 and elastically rotates and deforms away from the conductive contact surface 21, the clamping arm 31 of the spring 3 rotates to a certain angle, and the slot 321 on the fastening connecting arm 32 will fit onto the hook 331. After releasing the handle 4, under the elastic force of the spring 3 itself, the hook 331 will tightly hook onto the slot 321 to achieve a fastening connection. The fastening connecting arm 32 adopts a cantilever structure that can elastically deform. When the slot 321 on it contacts the hook 331, it can produce a certain degree of deformation, thereby ensuring that the hook 331 smoothly enters the slot 321 and preventing the fastening failure. Similarly, when releasing the spring 3, the prying device 62 pushes the fastening connecting arm 32, and the fastening connecting arm 32 itself produces a certain degree of elastic deformation, so that the slot 321 is removed from the hook 331, achieving a smooth release. In addition, the structure for the fixed buckle and the fixed locking point connection can also be a C-groove and ball head structure, or other fastening connection mechanism. These are all equivalent replacement structures that can be easily conceived by those skilled in the art based on this application, and are within the scope of protection of this application.

[0037] The fixed locking point also includes a positioning arm 33. One end of the positioning arm 33 is fixedly disposed in the receiving cavity of the insulating body, and the hook 331 is integrally formed on the other end of the positioning arm 33. The prying device 62 is sleeved on the outside of the positioning arm 33 of the fixed locking point. The prying device 62 can slide back and forth along the extension direction of the positioning arm 33. The prying device 62 can press tightly against the connecting arm 32 and slide towards the other end of the positioning arm 33 to disengage from the hook 331 on the positioning arm 33.

[0038] The positioning arm 33 can limit the prying device 62, ensuring that it is always in the prying position and preventing prying failure. At the same time, the positioning arm 33 forms a cantilever structure and has a certain elastic deformation capacity, which can work with the fastening connecting arm 32 to achieve smooth fastening and disengagement.

[0039] The positioning arm 33 is an elastic cantilever structure integrally formed on one end of the spring piece 3 by tearing and bending, and the other end of the positioning arm 33 is a free end.

[0040] The positioning arm 33 is integrally formed on the spring piece 3. It is made of metal, has high strength, and is integrally formed with the spring piece 3, resulting in low manufacturing cost and convenient assembly. In addition, the positioning arm 33 can also be integrally formed on the conductive terminal or integrally formed on the insulating body. These are equivalent alternative structures that are easily conceived by those skilled in the art based on this application and fall within the protection scope of this application.

[0041] The spring piece 3 has a V-shaped structure, with the bend of the V-shaped structure being an arc shape. The fastening connecting arm 32 and the positioning arm 33 are integrally formed on the two side walls of the V-shaped structure of the spring piece 3. A limiting wall 13 is fixedly provided inside the receiving cavity of the insulating body, forming a limiting channel between the limiting wall 13 and the inner wall of the receiving cavity. One side wall of the V-shaped structure of the spring piece 3 is stopped and clamped in the limiting channel. One end of the limiting wall 13 forms an arc-shaped support surface 131. The bend of the V-shaped structure of the spring piece 3 can elastically deform and fit on the outside of the arc-shaped support surface 131. A hollow part 132 is formed on the limiting wall 13. The free end of the positioning arm 33 is swung and inserted into the hollow part 132, and the two sides of the free end of the positioning arm 33 are stopped on the inner wall of the hollow part 132. The above structure facilitates the assembly and positioning of the spring piece 3. Furthermore, the hollow portion 132 on the limiting wall 13 guides and limits the elastic deformation direction of the positioning arm 33, preventing it from undergoing plastic deformation. In addition to the above structure, one side wall of the V-shaped structure of the spring piece 3 can also be fixed to the insulating body or conductive terminal by riveting, snap-fit ​​connection or other methods.

[0042] The triggering device 61 and the prying device 62 of the release mechanism 6 are integrally formed seesaw structures. One end of the seesaw structure forms the triggering device 61, and the other end forms the prying device 62. The triggering device 61 stops on the feed path of the wire 5 inserted into the receiving cavity through the wire inlet hole 12. The end of the wire 5 inserted into the receiving cavity to a set depth through the wire inlet hole 12 can tightly abut against the surface of the triggering device 61. The prying device 62 has a notch structure 621, which is sleeved on the outside of the positioning arm 33. The release mechanism 6 also includes an elastic reset member 63, which can provide the seesaw structure with an elastic reset force to maintain it at a specified angle.

[0043] When the wire 5 is inserted to a certain depth, it presses against the trigger device 61, causing the seesaw structure to flip at a certain angle. This causes the prying device 62 to swing and pry the fixing buckle off the fixing point. This structure only requires a small force from the wire 5 to the trigger device 61 to disengage the fixing buckle from the fixing point, without affecting the insertion of the wire 5. The trigger device 61 and the prying device 62 are integrally molded, which facilitates manufacturing, reduces manufacturing costs, and facilitates assembly. In addition, the trigger device 61 and the prying device 62 can also be separate linkage devices.

[0044] The elastic reset member 63 is an elastic cantilever structure installed on the inner wall of the receiving cavity of the insulating body. The triggering device 61 is integrally formed on the free end of the elastic reset member 63, and the prying device 62 is formed by tearing and bending the side wall of the elastic reset member 63. The elastic reset member 63 can also be a spring.

[0045] The root of the elastic reset member 63 is formed into a T-shaped positioning part 631 by tearing and bending in the reverse direction. A T-shaped positioning groove 14 is also provided in the receiving cavity of the insulating body. The T-shaped positioning part 631 at the root of the elastic reset member 63 is stopped and inserted into the T-shaped positioning groove 14. By forming the T-shaped positioning part 631 on the elastic reset member 63, and inserting the T-shaped positioning part 631 into the T-shaped positioning groove 14 in the receiving cavity of the insulating body, quick assembly and stable connection can be achieved. Alternatively, it can be fixedly connected to the receiving cavity by snap-fit ​​connection or riveting.

[0046] The insulating body is provided with a handle slide 15 communicating with the receiving cavity. The handle 4 is inserted into the handle slide 15, which can reciprocate a set distance. One end of the handle 4 extends out of the outside of the insulating body to form an operating end, and the other end of the handle 4 extends into the receiving cavity, forming an arc-shaped contact surface that can tightly abut against the other end of the spring 3. The handle 4 is preferably provided with a reset elastic element to provide the handle 4 with an elastic reset retaining force in the direction of the outside of the insulating body.

The conductive terminal includes a first conductive sheet 22 with a U-shaped structure and a second conductive sheet 23 with a U-shaped structure. The conductive contact surface 21 is located on both side walls of the U-shaped structure of the first conductive sheet 22. The plastic body 1 has two spaced-apart slots 11 with a connecting channel between them. The wire inlet hole 12 and the handle slide 15 are both located on the plastic body 1 and are connected to the slots 11 on the plastic body. The side wall of the slot 11 of the plastic body with the wire inlet hole 12 has a first conductive sheet slot 24, and the side wall of the slot 11 of the plastic body parallel to the axis of the wire inlet hole 12 has a second conductive sheet slot 25. The two ends of the first conductive sheet 22 are respectively inserted into the two first conductive sheet slots 24, and the bottom of the U-shaped structure of the first conductive sheet 22 is tightly inserted into the plastic body 1. Within the channel between the two upper slots 11, the outer surfaces of the two side walls of the first conductive sheet 22 U-shaped structure are tightly abutted against the inner side walls of the two slots 11 with the second conductive sheet slots 25. The two side walls of the second conductive sheet 23 U-shaped structure are respectively inserted into the channel formed between the side walls of the first conductive sheet 22 U-shaped structure and the second conductive slot and the limiting channel. A T-shaped limiting protrusion 15 is also provided in the limiting channel. A T-shaped notch 231 is provided on one side wall of the second conductive sheet 23 U-shaped structure. The T-shaped notch 231 of the second conductive sheet 23 is sleeved on the outside of the T-shaped limiting protrusion 15. The plastic cover is fastened to the plastic body 1. The plastic cover covers the surface of the slot 11 of the plastic body 1. The plastic cover and the slot 11 of the plastic body 1 together form a receiving cavity. The first conductive sheet 22 and the second conductive sheet 23 are tightly sandwiched between the plastic cover and the bottom surface of the slot 11 of the plastic body 1. The insulation body is designed as a split structure to facilitate the assembly of components and the injection molding of the insulation body. The conductive terminals also adopt a split structure to facilitate manufacturing and assembly.
