Description

Technical Field

[0001] The utility model belongs to the technical field of conductive terminals, and specifically refers to a stamping formed conductive anti - detachment terminal. Background Art

[0002] Products such as socket strips or wall switches used in life often use screw - pressing terminals for external wiring. When unscrewing the screw for wiring, the screw needs to be unscrewed and placed on one side. When inserting the power cord into the terminal hole, the screw is then screwed in to press the power cord. During this process, due to the relatively complex wiring environment, consumers often cannot find the screw, resulting in difficult wiring. At the same time, when the power cord is a multi - strand or single - core wire and is pressed by the screw, the multi - strand wire may be scattered or the single - core wire may be only half - pressed, leading to safety accidents. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is:

[0004] Consumers are not convenient to find the screw and cannot press the complete power cord.

[0005] To solve the above - mentioned technical problem, the technical solution proposed by the utility model is: a stamping formed conductive anti - detachment terminal, including a screw structure, a terminal structure, and a matching structure. The terminal structure is threadedly connected to the screw structure, and the screw structure and the terminal structure are arranged in the matching structure. The terminal structure includes a terminal body, which is formed into an overlapping end - to - end shape after stamping from a plate. The overlapping part forms the terminal top, and the central control part forms a terminal cavity. The bottom of the terminal body corresponding to the terminal top is the terminal bottom, and an anti - detachment rib formed by stamping is provided on the terminal bottom, and a machine screw hole is provided on the terminal top.

[0006] Further, the screw structure includes a cross - head machine screw, a screw spacer, a cross - head screw cap, and a toothless head. The cross - head machine screw is threadedly connected to the machine screw hole. The screw spacer is connected to the upper side of the cross - head machine screw, the cross - head screw cap is fixed to the upper side of the screw spacer, and the bottom of the cross - head machine screw is a toothless head.

[0007] Further, the matching structure includes a matching housing, which is divided into a cavity and a screw spacer groove by a partition, and an anti - detachment cap is provided on the upper side of the screw spacer groove.

[0008] In order to reduce rust and improve the conductive stability, a coating is provided on the surface of the terminal body.

[0009] Further, the terminal bottom is arranged in one of the shapes of an arc or a sharp angle.

[0010] Further, the screw insert is arranged in the screw insert groove, the cross machine thread screw penetrates through the partition board, and the cross machine thread screw and the terminal body are arranged in the cavity.

[0011] Further, the copper bar and the power cord are arranged between the toothless head and the anti - detachment rib.

[0012] The beneficial effects achieved by the present utility model with the above structure are as follows:

[0013] Using the stamping - formed conductive anti - detachment terminal can avoid the trouble of losing the screw when loosening the screw for wiring, and at the same time can improve the work efficiency of consumers or electricians;

[0022] The attached drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation to the present invention. Specific embodiments

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figure 1-6 shown, a stamping-formed conductive anti-detachment terminal proposed by the present invention includes a screw structure 1, a terminal structure 2, and a matching structure 3. The terminal structure 2 is threadedly connected to the screw structure 1, and the screw structure 1 and the terminal structure 2 are arranged in the matching structure 3. The terminal structure 2 includes a terminal body 8, and the terminal body 8 is formed into an end-to-end overlapping shape after being stamped from a plate. The overlapping part forms the terminal top 14, and the central control part forms the terminal cavity 11. The bottom of the terminal body 8 corresponding to the terminal top 14 is the terminal bottom 13. An anti-detachment rib 10 formed by stamping is provided on the terminal bottom 13, and a machine tooth hole 9 is provided on the terminal top 14.

[0025] To improve the clamping flexibility, the screw structure 1 includes a Phillips machine screw 4, a screw medium 5, a Phillips screw cap 6, and a toothless head 7. The Phillips machine screw 4 is threadedly connected to the machine tooth hole 9. The screw medium 5 is connected to the upper side of the Phillips machine screw 4. The Phillips screw cap 6 is fixed to the upper side of the screw medium 5. The bottom of the Phillips machine screw 4 is the toothless head 7.

[0026] To perform limit matching on the screw structure 1 and the terminal structure 2, the matching structure 3 includes a matching housing 16. The matching housing 16 is divided into a cavity 17 and a screw medium groove 19 by a partition. An anti-detachment cap 18 is provided on the upper side of the screw medium groove 19.

[0027] To reduce rust and improve the conductive stability, a coating 12 is provided on the surface of the terminal body 8.

[0028] In order to increase the contact area, keep the power line in the middle position at all times, and improve effectiveness and stability, the terminal bottom 13 is set in one of the shapes of an arc or a pointed angle.

[0029] The screw media 5 is clamped in the screw media slot 19 , the cross machine screw 4 is set through the partition, the cross machine screw 4 and the terminal body 8 are set in the cavity 17 , and the copper bar 15 and the power line 21 are set between the toothless head 7 and the anti-slip rib 10 .

[0030] An electrical connection terminal and a terminal manufacturing method are used. The terminal body 8 is made of a plate of a fixed width. After punching and pressing the anti-stripping ribs on the plate, the plate is overlapped head to tail to form a closed shape by bending or stamping the sheet metal, and the overlapping holes are tapped, and then the terminal body 8 is plated. When in use, the cross machine screw 4 is screwed into the machine thread hole 9 to form a terminal assembly. When the terminal assembly is used in the corresponding product structure design, only a retaining wall is provided on the upper end of the screw medium 5 to prevent the screw from falling off when the screw is loosened. A copper strip 15 of a certain width is inserted into the terminal cavity 11. When the screw medium 5 is rotated, the terminal structure 2 moves upward to press the power line 21 and the copper strip 15, so that the connection is efficient, reliable and stable. The bottom 13 of the terminal is in an arc shape or a sharp angle shape. The machine thread hole 9 of the top 14 of the terminal needs to be centrally aligned. The 8 plating mainly ensures that the 6 terminal will not rust and improves the conductive stability.

[0031] After the terminal body 8 is produced, the cross machine screw 4 is screwed into the machine thread hole 9 manually or by equipment. During the screwing process, the threadless head 7 first enters the machine thread hole 9 and plays a guiding role. After entering the top, the machine thread on the screw structure 1 is screwed in smoothly and ensures that a certain distance is kept between the screw medium 5 and the upper surface of the terminal top 14, so that it can be used with other product structures in the future without adjusting the spacing;

[0032] Embodiment 1

[0033] The terminal body 8 is placed in the cavity 17, and the cross machine screw 4 is inserted from the anti-drop cap 18 on the top of the matching housing 16 to the machine hole 9 at the same time and pressed into the screw media slot 19 under a certain pressure. When the cross machine screw 4 is rotated, the terminal body 8 moves upward, and the screw media 5 presses against the anti-drop cap 18 by rotating the cross screw cap 6 to move the terminal body 8 downward. When the bottom 13 of the terminal contacts the bottom of the cavity 17, the toothless head 7 of the cross machine screw 4 is just at the end of the machine hole 9 of the terminal body 8. When the cross machine screw 4 is rotated continuously, the terminal body 8 will no longer move downward. At this time, the copper bar 15 is inserted into the terminal cavity 11 and the power cord 21 is inserted into the terminal cavity 11 at the same time. The cross machine screw 4 is rotated in the opposite direction, and the bottom 13 of the terminal presses against the copper bar 15, and the terminal body 8 moves upward, thereby tightly locking the copper bar 15 and the power cord 21 together. Because there is an anti-drop rib 10 inside the terminal cavity 11, the power cord 21 can be locked more firmly and is not easy to fall off.

[0034] Embodiment 2

[0035] As another embodiment of the present application, the anti - detachment cap 18 is semicircularly arranged, and a guiding card slot 20 is opened on the partition at the bottom of the screw medium groove 19.

[0036] The screw medium 5 of the supporting housing 16 is aligned with the screw medium groove 19, the terminal body 8 is aligned with the cavity 17, and the space between the screw medium 5 and the top 14 of the terminal is aligned with the guiding card slot 20. The terminal assembly is loaded into the supporting housing 16 through a tool or fixture. When the cross - recessed machine screw 4 is rotated, the screw medium 5 presses against the semicircular anti - detachment cap 18, causing the terminal body 8 to move downward. When the bottom 13 of the terminal touches the bottom of the cavity 17, the toothless head 7 of the cross - recessed machine screw 4 is just at the end of the threaded hole 9 of the terminal body 8. When the cross - recessed machine screw 4 is further rotated, the terminal body 8 will no longer move downward. At this time, the copper bar 15 is inserted into the terminal cavity 11 and at the same time the power cord 21 is inserted into the terminal cavity 11. The cross - recessed machine screw 4 is rotated in the reverse direction. The bottom 13 of the terminal presses against the copper bar 15, and the terminal body 8 moves upward, thus tightly locking the copper bar 15 and the power cord 21 together. Because there is an anti - detachment rib 10 inside the terminal cavity 11, the power cord 21 can be locked more firmly and is not easy to fall off.
