Description

Technical Field

[0001] The present invention relates to a connector, in particular to a connector structure with a rotating handle. Background Art

[0002] The tool-free terminal for connecting electrical conductors generally consists of an insulating body, a cover, a handle, a spring piece and a metal clip. Existing tool-free products are equipped with operating rods. The common feature of these operating rods is that they all perform circular motion, thereby deforming the spring piece to achieve the purpose of wire entry / withdrawal. Currently, the operating rods are all installed on the insulating body with a rotating shaft as the rotation center. Generally, a rotating shaft or a shaft hole is fixedly formed on the insulating body, and a matching shaft hole or rotating shaft is formed on the operating rod. The operating rod is rotationally positioned on the insulating body by inserting the rotating shaft into the shaft hole. However, due to the shaft hole structure, there are technical limitations in mold forming for this type of method, and it can usually only be applied to spliced terminals. When applied to an integrally formed terminal block, this method can no longer be used. Summary of the Invention

[0003] In order to overcome the above defects, the present invention provides a connector structure with a rotating handle. The connector structure with a rotating handle can meet the tool-free requirements of an integrally formed terminal block, meet the usage requirements of quickly disconnecting and connecting wires, improve the tooling efficiency, and enhance the actual competitiveness of the product.

[0004] The technical solution adopted by the present invention to solve its technical problems: A connector structure with a rotating handle includes a plastic housing, a conductive clip, a spring piece and a driving handle. The conductive clip is fixedly installed inside the plastic housing. One end of the spring piece is fixedly installed on the side wall of the conductive clip, and the other end of the spring piece can elastically abut against the conductive plate on the conductive clip. One end of the driving handle forms a sleeve structure, and the other end of the driving handle forms an operating rod. The sleeve structure at one end of the driving handle is sleeved outside the spring piece. An opening communicating with its inner cavity is formed on the side wall of the plastic housing. The operating rod at the other end of the driving handle extends out of the plastic housing through the opening, and the operating rod of the driving handle can swing a certain angle in the opening. The sleeve structure at one end of the driving handle stops inside the plastic housing. One side wall of the sleeve structure at one end of the driving handle can abut against the side wall of the spring piece as the driving handle swings, and the side wall of the spring piece is pressed by one side wall of the sleeve structure of the driving handle to deform so that its other end moves in a direction away from the conductive plate of the conductive clip.

[0005] As a further improvement of the present invention, the spring piece is a V-shaped metal spring piece. The end of the V-shaped metal spring piece on the side of the bend forms a fixed end, and the end of the V-shaped metal spring piece on the other side of the bend forms a clamping end. The sleeve structure at one end of the driving handle is sleeved outside the bend of the V-shaped structure of the spring piece, and the side wall of the sleeve structure of the driving handle can tightly abut against the side wall of the V-shaped metal spring piece on the other side of the bend to make the clamping end move in a direction away from the conductive plate of the conductive clip.

[0006] As a further improvement of the present invention, the driving handle includes a connecting plate, an inner shaft and a shaft sleeve. One end of the connecting plate extends out of the plastic housing through an opening on the side wall of the plastic housing to the outside of the plastic housing. One end of the connecting plate forms an operating rod. The inner shaft and the shaft sleeve are respectively fixed on the side wall of the other end of the connecting plate, and the shaft sleeve is wrapped around the periphery of the inner shaft. The bent part of the V-shaped metal elastic sheet can just be accommodated in the accommodating channel with both ends open formed between the inner shaft and the outer sleeve. The other end of the connecting plate, the inner shaft and the outer sleeve together form a sleeve-like structure of the driving handle.

[0007] As a further improvement of the present invention, the bent part of the V-shaped metal elastic sheet forms an arc-shaped structure. The shaft sleeve is an arc-shaped sheet structure matching the outer shape of the bent part of the V-shaped metal elastic sheet. An eccentric pressing part is formed on the inner side wall of the arc-shaped sheet structure on the other side of the bent part of the V-shaped metal elastic sheet. The eccentric pressing part just closely fits against the side wall of the V-shaped metal elastic sheet on the other side of the bent part.

[0008] As a further improvement of the present invention, an arc-shaped guiding surface matching the outer shape of the shaft sleeve of the sleeve-like structure at one end of the driving handle is formed on the inner side wall of the plastic housing. The outer side surface of the shaft sleeve on the driving handle abuts against the surface of the arc-shaped guiding surface.

[0009] As a further improvement of the present invention, the plastic housing includes a plastic body and a plastic cover. The plastic body is in a barrel-shaped structure with one end open. The opening on the plastic housing for the operating rod of the driving handle to extend out and the wire inlet for the wire to enter and exit are both located on the bottom surface of the barrel-shaped structure of the plastic body. The conductive clip, the elastic sheet and the driving handle can be loaded into the plastic body through the open end of the plastic body. The plastic cover can be detachably and fixedly covered on the open end of the plastic body.

[0010] As a further improvement of the present invention, the conductive clip includes a conductive plate, a clip fitting end and a fixing plate. The conductive plate and the clip fitting end are respectively fixedly installed on both sides of the fixing plate along the wire insertion direction. A fixing groove and a clip channel communicating with each other are formed in the plastic cover. The fixing plate can be accommodated in the fixing groove, and the side of the fixing plate facing away from the conductive plate abuts against the bottom surface of the fixing groove, and the side wall perpendicular to the wire insertion direction closely adheres to the inner side wall of the fixing groove. The clip fitting end can be accommodated in the clip channel. An inner convex stop wall is provided on the inner side wall of the plastic body. The end of the conductive plate of the conductive clip facing away from the fixing plate can tightly abut against the inner convex stop wall.

[0011] As a further improvement of the present invention, the end of the conductive plate of the conductive clip facing away from the fixing plate forms an inclined and outwardly warped structure. A groove structure for accommodating the end of the conductive plate is formed on the surface of the inner convex stop wall on the inner side wall of the plastic body, and a slope structure capable of closely fitting with the inclined and outwardly warped structure of the conductive clip is formed on the side wall of the groove structure.

[0012] As a further improvement of the present invention, a convex hull is fixedly provided on one side wall of the fixed plate along the direction perpendicular to the insertion direction of the wire. A perforation is provided on the side wall of the V-shaped metal elastic sheet at the turning side. The convex hull can be inserted into the perforation. A limiting baffle is also fixedly provided in the fixing groove of the plastic cover. A gap is formed between the limiting baffle and the side wall of the fixing groove, which is only enough to accommodate the side wall of the V-shaped metal elastic sheet at the turning side and the side wall of the fixed plate.

[0013] As a further improvement of the present invention, the width of one end of the connecting plate is smaller than that of the other end, and a convex block for finger pinching is fixedly formed at the end of one end of the connecting plate. The opening on the side wall of the plastic shell is a T-shaped structure matching one end of the connecting plate and the convex block thereon. One end of the connecting plate and the convex block thereon can just extend out of the outside of the plastic shell through the opening, and one end of the connecting plate can swing by a set angle in the opening.

[0014] The beneficial effects of the present invention are as follows: By forming a sleeve-like structure on the driving handle and sleeving it outside the elastic sheet, and by pulling the operating rod of the driving handle exposed outside the plastic shell, the driving handle can be swung, and the sleeve-like structure can make the elastic sheet swing and deform accordingly, changing the distance between the elastic sheet and the conductive plate of the conductive clip. When wiring and rewiring in the present invention, no tools are required. The driving handle can be directly rotated to open the elastic sheet for wiring. There is no need to form a shaft or shaft hole structure on the plastic shell, and it is not limited by the requirements of plastic molding. The application range is relatively large and it is applicable to all types of products. Description of the Drawings

[0027] Embodiment: A connector structure for a rotating handle, comprising a plastic housing, a conductive clip 1, a spring piece 2 and a drive handle 3. The conductive clip 1 is fixedly installed inside the plastic housing. One end of the spring piece 2 is fixedly installed on the side wall of the conductive clip 1, and the other end of the spring piece 2 can elastically abut against the conductive plate 11 on the conductive clip 1. One end of the drive handle 3 forms a sleeve structure, and the other end of the drive handle 3 forms an operating rod. The sleeve structure at one end of the drive handle 3 is sleeved outside the spring piece 2. An opening 4 communicating with the inner cavity is formed on the side wall of the plastic housing. The operating rod at the other end of the drive handle 3 extends out of the plastic housing through the opening 4, and the operating rod of the drive handle 3 can swing a certain angle in the opening 4. The sleeve structure at one end of the drive handle 3 abuts against the inside of the plastic housing. One side wall of the sleeve structure at one end of the drive handle 3 can abut against the side wall of the spring piece 2 as the drive handle 3 swings. The side wall of the spring piece 2 is deformed by the abutment of one side wall of the sleeve structure of the drive handle 3, so that the other end thereof moves in a direction away from the conductive plate 11 of the conductive clip 1.

[0028] During use, there is no need to provide a rotating shaft and shaft hole structure on the plastic housing and the drive handle 3. The drive handle 3 is directly sleeved outside the spring piece 2. By pulling the drive handle 3 to swing inside the plastic housing, the spring piece 2 can be deformed, and then the other end thereof moves in a direction away from the conductive plate 11, so as to realize the smooth insertion or extraction of the wire 22. The connector structure is simple, the plastic housing is convenient for injection molding, it can be applied to an integrally formed terminal block, and no additional tool is required during the insertion and extraction of the wire, so the operation is convenient.

[0029] The shrapnel 2 is a V-shaped metal shrapnel 2. The end of the V-shaped metal shrapnel 2 on the side of the bend forms a fixed end, and the end of the V-shaped metal shrapnel 2 on the other side of the bend forms a clamping end. The sleeve structure at one end of the driving handle 3 is sleeved on the outside of the bend of the V-shaped structure of the shrapnel 2. The side wall of the sleeve structure of the driving handle 3 can tightly abut against the side wall of the V-shaped metal shrapnel 2 on the other side of the bend, causing the clamping end to move away from the conductive plate 11 of the conductive clip 1. By using the V-shaped metal shrapnel 2 and sleeving the sleeve structure of the driving handle 3 on the bend of the V-shaped metal shrapnel 2, when the driving handle 3 is rotated, it will press against the other side wall of the V-shaped metal shrapnel 2, causing its bend to deform, changing the V-shaped angle, and further causing the clamping end of the V-shaped metal shrapnel 2 to move towards the fixed end direction, changing the distance between the clamping end of the shrapnel 2 and the conductive plate 11 of the conductive clip 1, facilitating the insertion and extraction of the wire. After releasing the driving handle 3, the clamping end of the V-shaped metal shrapnel 2 automatically resets to form a clamping state.

[0030] The driving handle 3 includes a connecting plate 5, an inner shaft 6, and a sleeve 7. One end of the connecting plate 5 extends out of the plastic housing through the opening 4 on the side wall of the plastic housing. One end of the connecting plate 5 forms an operating rod. The inner shaft 6 and the sleeve 7 are respectively fixed on the side wall of the other end of the connecting plate 5, and the sleeve 7 covers the periphery of the inner shaft 6. The bend of the V-shaped metal shrapnel 2 can just be accommodated in the accommodating channel with two open ends formed between the inner shaft 6 and the outer sleeve. The other end of the connecting plate 5, the inner shaft 6, and the outer sleeve together form the sleeve structure of the driving handle 3. The bend of the V-shaped metal shrapnel 2 is in the accommodating channel between the sleeve 7 and the inner shaft 6 of the driving handle 3. This structure realizes the positioning of the V-shaped metal shrapnel 2 in the sleeve structure of the driving handle 3 and avoids the separation of the driving handle 3 and the V-shaped metal shrapnel 2.

[0031] The bend of the V-shaped metal shrapnel 2 forms an arc-shaped structure. The sleeve 7 is an arc-shaped sheet structure matching the outer shape of the bend of the V-shaped metal shrapnel 2. The inner side wall of the arc-shaped sheet structure on the other side of the bend of the V-shaped metal shrapnel 2 forms an eccentric pressing portion, and the eccentric pressing portion just tightly fits against the side wall of the V-shaped metal shrapnel 2 on the other side of the bend. The bend of the V-shaped metal shrapnel 2 forms an arc-shaped structure. When the driving handle 3 rotates, the sleeve 7 rotates around the arc-shaped structure of the bend of the V-shaped metal shrapnel 2, which can avoid jamming and ensure smooth rotation. The length of the side wall of the sleeve 7 on the other side of the bend of the V-shaped metal shrapnel 2 is preferably greater than the side wall on one side of the bend of the V-shaped metal shrapnel 2. On the one hand, this can increase the pressing force arm, enabling the shrapnel 2 to be toggled with a smaller force. On the other hand, it saves space and makes the size of the plastic housing as small as possible.

[0032] An arc-shaped guiding surface 8 matching the outer shape of the shaft sleeve 7 of the sleeve-like structure at one end of the driving handle 3 is formed on the inner side wall of the plastic housing. The outer side surface of the shaft sleeve 7 on the driving handle 3 abuts against the surface of the arc-shaped guiding surface 8. Under the elastic force of the V-shaped metal elastic sheet 2, the outer side surface of the shaft sleeve 7 of the driving handle 3 will always abut against the arc-shaped guiding surface 8 on the inner side of the plastic housing. When the outer sleeve rotates with the driving handle 3, the arc-shaped guiding surface 8 forms a rotational guide, enabling the driving handle 3 to rotate smoothly.

[0033] The plastic housing includes a plastic body 9 and a plastic cover 10. The plastic body 9 has a barrel-shaped structure with one end open. The opening 4 on the plastic housing through which the operating rod of the driving handle 3 extends and the wire inlet for wire entry and exit are both located on the bottom surface of the barrel-shaped structure of the plastic body 9. The conductive clip 1, the elastic sheet 2, and the driving handle 3 can be inserted into the interior of the plastic body 9 through the open end of the plastic body 9, and the plastic cover 10 can be detachably fixed and covered on the open end of the plastic body 9. During assembly, first, the V-shaped metal elastic sheet 2, the conductive clip 1, and the driving handle are assembled together; then the above semi-finished product is inserted into the plastic body 9, and finally, the plastic cover 10 is covered, which makes the structure convenient for assembly.

[0034] The conductive clip 1 includes a conductive plate 11, a clip mating end 12, and a fixing plate 13. The conductive plate 11 and the clip mating end 12 are respectively fixedly installed on both sides of the fixing plate 13 along the wire insertion direction. A fixing groove 14 and a clip channel that communicate with each other are formed in the plastic cover 10. The fixing plate 13 can be accommodated in the fixing groove 14, and the side of it facing away from the conductive plate 11 abuts against the bottom surface of the fixing groove 14, and its side wall perpendicular to the wire insertion direction closely adheres to the inner side wall of the fixing groove 14. The clip mating end 12 can be accommodated in the clip channel. An inner convex stop wall 15 is provided on the inner side wall of the plastic body 9. The end of the conductive plate 11 of the conductive clip 1 facing away from the fixing plate 13 can tightly abut against the inner convex stop wall 15. The fixing groove 14 of the plastic cover 10 and the inner convex stop wall 15 on the plastic body 9 realize the stop and positioning of the wire plate and the fixing plate 13 in three mutually perpendicular directions, and its structure is simple and convenient for assembly.

[0035] The end of the conductive plate 11 of the conductive clip 1 facing away from the fixing plate 13 forms an inclined and outwardly warped structure 16. A groove structure for accommodating the end of the conductive plate 11 is formed on the surface of the inner convex stop wall 15 on the inner side wall of the plastic body 9, and the side wall of the groove structure forms an inclined surface structure 17 that can closely fit with the inclined and outwardly warped structure 16 of the conductive clip 1. The end of the guiding plate forms an inclined and outwardly warped structure 16, which cooperates with the inclined surface of the inner groove structure on the inner convex stop wall 15 on the inner side wall of the plastic body 9. The conductive plate is pressed through the inclined surface, and this structure forms an elastic pressing. Even if there is an error in the processing of the length direction of the conductive plate 11, it does not affect the installation stability of the conductive clip 1 in the plastic housing, and it always remains in a fixed state.

[0036] A convex hull 18 is fixedly provided on one side wall of the fixed plate 13 along the direction perpendicular to the insertion direction of the wire. A perforation 19 is provided on the side wall of the V-shaped metal elastic sheet 2 on the turning side. The convex hull 18 can be inserted into the perforation 19. A limit baffle 20 is also fixedly provided in the fixing groove 14 of the plastic cover 10. A gap is formed between the limit baffle 20 and the side wall of the fixing groove 14, which is only for accommodating the side wall of the V-shaped metal elastic sheet 2 on the turning side and the side wall of the fixed plate 13. Through the insertion of the convex hull 18 on the side wall of the fixed plate 13 and the perforation 19 on the fixed end of the V-shaped metal elastic sheet 2, and at the same time, through the blocking of the side wall of the plastic cover 10 and the limit baffle 20, the stopping and positioning of the fixed end of the V-shaped metal elastic sheet 2 are realized, and this structure is convenient for assembly.

[0037] The width of one end of the connecting plate 5 is smaller than that of the other end, and a convex block 21 for finger pinching is fixedly formed at the end of one end of the connecting plate 5. The opening 4 on the side wall of the plastic shell is a T-shaped structure matching the one end of the connecting plate 5 and the convex block 21 thereon. The one end of the connecting plate 5 and the convex block 21 thereon can just extend out of the plastic shell through the opening 4, and one end of the connecting plate 5 can swing a set angle in the opening 4. The above structure enables the connecting plate 5 and the convex block 21 on one end thereof to smoothly extend from the inside of the plastic body 9 to the outside. At the same time, the other end of the connecting plate 5 is blocked, and the convex block 21 on one end of the connecting plate 5 is also convenient for the user to pinch and operate. Arc surfaces and patterns matching the finger pulp of a human finger can be provided on the two side walls of the convex block 21 for pinching, which is convenient for operation.
