Compared with the prior art, the beneficial effects of the utility model reside in that: when the riveting head is used for riveting a substrate and a conductive copper wire of an LED light bar, due to the fact that the middle section of the head is provided with a prefabricated part formed by reducing the diameter of the cylindrical surface, when the head is subjected to axial stamping, stress deformation with the prefabricated part as a base point is generated, the position of the final bending deformation of the head is determined, and the riveting tightness in accordance with design expectation is obtained.
Description
Technical Field
The utility model relates to an electrical technology field, specific indicates to be used for the copper line rivet of LED lamp strip.
Background
The LED lamp strip is an LED series lighting product, a strip-shaped substrate is adopted, high-brightness LEDs are packaged on the front surface of the substrate in a surface-mounted mode and serve as light sources, one or more LEDs are usually used as a circuit unit, and the LED lamp strip can be cut off and taken according to the required length without damaging the circuit unit.
In order to connect the circuit units on the LED lamp strips in series or in parallel, the back of the substrate is provided with conductive copper wires to construct a series or parallel circuit, the front of the substrate is provided with rivets which penetrate through the conductive copper wires from the circuit units to the back of the substrate, and the rivets are axially punched to enable the rivet heads to be bent to form a riveting structure, so that the conductive copper wires are electrically connected with the circuit units.
The rivet used in the prior art is mostly shown in fig. 1, and comprises a nail head 1 ', the bottom surface of the nail head is provided with a nail head 2' which extends downwards perpendicular to the nail head, the nail head 2 'is a columnar structure with the same diameter throughout, and the position of bending of the nail head 2' when the nail head is subjected to axial punching has uncertainty. The bent position of the nail head 2 'is too close to the nail cap 1', so that the riveting is too tight, and the conductive copper wire and the LED lamp strip are easily broken; the bent position of the nail head 2 'is far away from the nail cap 1', which leads to too loose riveting and poor conduction.
SUMMERY OF THE UTILITY MODEL
In order to compensate for the above-mentioned not enough of prior art, the utility model provides a copper line rivet in LED lamp strip, its technical scheme as follows.
The copper wire rivet for the LED light bar comprises a nail cap, wherein a nail head which is vertical to the nail cap and extends downwards is arranged on the bottom surface of the nail cap, and the nail head is of a columnar structure; the middle section of the nail head is provided with a prefabricated part formed by reducing the diameter of the cylindrical surface.
Compared with the prior art, the beneficial effects of the utility model reside in that:
when the riveting head is used for riveting a substrate and a conductive copper wire of an LED light bar, due to the fact that the middle section of the head is provided with a prefabricated part formed by reducing the diameter of the cylindrical surface, when the head is subjected to axial stamping, stress deformation with the prefabricated part as a base point is generated, the position of the final bending deformation of the head is determined, and the riveting tightness in accordance with design expectation is obtained.
The present invention will be further described with reference to the drawings and the detailed description.

Fig. 2 is a schematic structural diagram of the present invention.
Fig. 3 is a usage state diagram of the present invention.
Detailed Description
As shown in fig. 2 and 3, the copper wire rivet for the LED light bar comprises a nail cap 1, wherein a nail head 2 which extends downwards perpendicular to the nail cap 1 is arranged on the bottom surface of the nail cap 1, and the nail head 2 is of a cylindrical structure; the middle section of the stud 2 has a preformed portion 21 of reduced cylindrical diameter.
In the most basic embodiment, only the middle section of the stud 2 needs to be punched to obtain the preform 21 intended by the above solution.
When the copper wire rivet for the LED light bar is used for riveting the substrate of the LED light bar and the conductive copper wire, due to the fact that the middle section of the nail head 2 is provided with the prefabricated part 21 formed by reducing the diameter of the cylindrical surface, when the nail head 2 is subjected to axial stamping, stress deformation with the prefabricated part 21 as a base point is generated, the position of final bending deformation of the nail head 2 is determined, and riveting tightness according with design expectation is obtained.
As an improvement of the technical proposal, the prefabricated part 21 is taken as a boundary, the upper section of the nail head 2 is of a cylindrical structure with the same overall diameter, the lower section of the nail head 2 is also of a cylindrical structure with the same overall diameter, and the diameter of the lower section of the nail head 2 is smaller than that of the upper section of the nail head 2. In the improved scheme, the nail head 2 is still a revolving body with the same central axis as a whole, so that the nail head 2 can be better supported to penetrate through the LED lamp strip and the conductive copper wire, and cannot be bent and deformed in advance in the penetrating process. And, the lower section of the nail head 2 mainly plays a role of bending deformation to complete riveting, and the physical damage to the conductive copper wire can be avoided by adopting a smaller diameter.
As a further improvement of the above technical solution, the preformed portion 21 is in the shape of a frustum, the diameter of the upper end thereof is the same as the upper section of the stud 2, and the diameter of the lower end thereof is the same as the lower section of the stud 2. The significance of this improvement is that the conical frustum-shaped configuration of the preform 21 is utilized to further define the base point of stress deformation of the stud 2 when subjected to axial stamping at the lower end of the preform 21, enhancing fault tolerance.
In a preferred embodiment, the end of the stud 2 is shaped in a cone to facilitate penetration.
For those skilled in the art, the protection scope of the present invention is not limited to the details of the above-described exemplary embodiments, and all the embodiments with variations within the scope and meaning equivalent to the elements of the present invention should be included in the present invention without departing from the spirit or essential characteristics of the present invention.
