Description

Contact shrapnel for power connector

The invention relates to a contact elastic piece for a power connector, in particular to a contact elastic piece capable of effectively overcoming contact failure and effective use space in use; by providing a card portion and a contact portion in the elastic body, using the card portion The pits and the circuit board form a non-planar surface to increase the friction, and the contact portion has a "several" shape to enhance the elasticity thereof to alleviate the impact on the outside, effectively overcome the poor contact during use and effectively utilize the space, thereby achieving the purpose of simplicity and practicality.

At present, various digital electronic products such as mobile phones, Mp3, and digital cameras are widely used, and they are almost essential items for people, which bring great convenience to people's lives and greatly improve the quality of life, but these electronic products have one thing in common. The point is that you need to have electricity to use. As a result, power connectors are a must-have for these electronics, but current power connectors are often too bulky to carry, or they can be damaged by poor contact after a period of use.

In the prior art, the shrapnel of the power connector usually adopts an axial structure generally adopting a planar and downward wiring manner. The former is easy to be loosened during use, and the contact is poor during use, and the latter is used for downward wiring. Waste space and reduce space utilization.

In view of the shortcomings caused by the above-mentioned prior art, the present invention has invented a solution to the shortcomings of the prior art. The main purpose of the contact elastic piece of the power connector is to effectively overcome the lack of contact during use and the lack of contact elastic piece for effectively utilizing space, and it is practical; by using the card portion and the contact portion in the spring body, the card portion is utilized. The concave point and the circuit board form a non-planar surface to increase the friction, and the contact portion has a "several" shape to enhance the elasticity thereof to mitigate the impact on the outside, effectively overcome the poor contact during use and effectively utilize the space, thereby achieving the purpose of simple and practical use. .

In order to achieve the above objective, the present invention provides a contact elastic piece for a power connector, which mainly includes: a spring body having a latching portion and a contact portion; and a latching portion having an end portion of the latching portion The bump is deeply latched with the circuit board and provided with a pit; a contact portion having a "several" shape to be electrically connected to the contact piece and the contact head; and a connecting portion disposed at the card position Between the portion and the contact portion, a fixing hole is arranged thereon to fix the elastic body to the inside of the power connector by the high-pressure riveting; and the recessed portion and the circuit of the card portion are used by providing the latch portion and the contact portion in the elastic body The plate is formed into a non-planar surface to increase the friction, thereby effectively overcoming the contact failure during use and effectively utilizing the space, and when the contact portion is electrically connected with the contact piece and the contact head in a "several" shape, the elasticity is enhanced to mitigate the impact on the outside, and the interference is effectively overcome. The use of poor contact and efficient use of space, thus achieving a simple and practical purpose.

Another object of the present invention is to provide a card portion at the outer end of the connecting portion for the purpose of increasing variability.

Figure 3 is a schematic illustration of an embodiment of the invention.

The content and other features of the present invention will be described in detail below with reference to the embodiments of the accompanying drawings. After that, it tends to be clear.

As shown in FIG. 1 to FIG. 2, the contact elastic piece for the power connector of the present invention mainly includes: a spring body 1 having a latching portion 11 and a contact portion 12, both of which are located The same side can reduce the space occupied by the power connector; a card portion 11 having a bump 111 at the end of the card portion 11 for deep clamping with the circuit board, and having a recess 112; a contact portion 12, The contact portion 12 has a shape of "several" to be electrically connected to the contact piece and the contact head; a connecting portion 13 is disposed between the latching portion 11 and the contact portion 12, and is provided with a fixing hole 131 for riveting at a high voltage. The cooperation of the spring body 1 is fixed inside the power connector; by providing the latch portion 11 and the contact portion 12 in the spring body 1, the bump 112 of the latch portion 11 is used to form a non-planar surface with the circuit board to increase friction, thereby effectively To overcome the poor contact and effective use of space during use, and to make the contact portion 12 electrically connected to the contact piece and the contact head by using a "several" shape, the elasticity is enhanced to mitigate the impact on the outside, and the contact failure and effective use of space are effectively overcome. Thus achieving a simple and practical purpose

Another object of the present invention is to provide the card portion 11 at the outer end of the connecting portion 13 for the purpose of increasing variability for practical purposes (as shown in Fig. 3).

In summary, the structure of the invention is novel and practical, and the function is far superior to the progressive and industrial use value of the formula, and is in combination with the patent application requirements, and is an invention patent application according to law.

The specific embodiments described above are intended to describe the purpose, features, and effects of the present invention.
