Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a one piece staple strip.

Description of the Prior Art

In many fields, there is often a need to arrange cables according to different environments or operational needs, wherein the cables may be electrical cables or non-electrical cables. Specifically, the requirement of arranging conductive cables in order to build a circuit is more common.

The cable is usually fixed on a mounting base (such as wood or cement base). Since the cable is very long and flexible, it is not easy to make it straight and positioned. Therefore, a stapler with staples (such as U-shaped staples) is commonly used to fix the cable. However, there is none of effective connection structure between the adjacent U-shaped staples of a conventional staple strip, which causes the arrangement of the U-shaped staples to be dislocated and not straight. Furthermore, the conventional staple strip is not provided with a guiding structure which is configured to match with the cartridge of a stapler, so that the stapling effect is worse, it is easy to jam, and it is easy to damage the cable.

A conventional cable fixing method is carried out by passing a U-shaped metal staple through a plastic member having a holding notch. The conventional cable fixing device is not formed of one piece, which is difficult to manufacture and expensive, and the metal staple is easy to cause damage to the cable, leakage of electricity and short circuit.

The present invention is, therefore, arisen to obviate or at least mitigate the above-mentioned disadvantages.

SUMMARY OF THE INVENTION

The main object of the present invention is to provide a one piece staple strip which is straight and good in holding a cable.

To achieve the above and other objects, a one piece staple strip is provided, including: a plurality of staples, each of the plurality of staples including two leg portions and a crown portion connected with and between the two leg portions; a connection portion, connected with and between every neighboring two staples of the plurality of staples; and a stop portion, projecting laterally from the leg portion of each of the plurality of staples and defining a holding space with the crown portion of each of the plurality of staples, the holding space being configured to receive a cable; wherein each of the two leg portions of each of the plurality of staples includes a spike section extending from the stop portion.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIGS. 1 to 7 for a preferable embodiment of the present invention. A one piece staple strip 1 of the present invention includes a plurality of staples 10, a connection portion and a stop portion 40. The one piece staple strip 1 may be made of a material such as plastic, metal or any material having sufficient structural strength.

Each of the plurality of staples 10 includes two leg portions 11 and a crown portion 12 connected with and between the two leg portions 11. The connection portion is connected with and between every neighboring two staples of the plurality of staples 10. The stop portion 40 projects laterally from the leg portion 11 of each of the plurality of staples 10 and defines a holding space 13 with the crown portion 12 of each of the plurality of staples 10, and the holding space 13 is configured to receive a cable. Each of the two leg portions 11 of each of the plurality of staples 10 includes a spike section 111 extending from the stop portion 40. Whereby, it ensures that the one piece staple strip 1 extends straightly and holds the cable appropriately. The staple 10 may be shaped in U-shape or any configuration having a holding space.

The connection portion includes at least one of a first connection portion 20 and a second connection portion 30 (preferably both), the first connection portion 20 is connected with and between the crown portions 12 of neighboring two staples of the plurality of staples 10, and the second connection portion 30 is connected with and between the leg portions 11 of neighboring two staples of the plurality of staples 10. In this embodiment, the holding space 13 includes two straight sides 131 opposite to each other, two shoulders 132, and a concave side 133. The two shoulders 132 are connected laterally to the two straight sides 131, respectively. The concave side 133 is connected to an end of one of the two shoulders 132 and an end of the other of the two shoulders 132. An extending line of the two shoulders 132 divides the holding space 13 into a rectangular region 134 and a segment region 135. The rectangular region 134 is configured to be applied to a cable which is rectangular or flat, and the segment region 135 is configured to be applied to a cable which is circular.

The crown portion 12 of each of the plurality of staples 10 includes a projection 121 at a top side thereof. The projection 121 is configured to cooperate with a groove 511 on an inner surface of a cartridge 51 of a stapler 50. The projection 121 serves as a mechanism for stabilization and positioning of staples of different sizes within the groove 511 so that each of the plurality of staples 10 can be well stabilized and positioned. The spike section 111 of each of the plurality of staples 10 includes a tapered end 112 which is a free end, and the tapered end 112 includes an inner inclined face 113 and an outer inclined face 114. An extent of the outer inclined face 114 is smaller than an extent of the inner inclined face 113 so that the staple 10 can come into a mounting base (such as wood or cement base). Preferably, the spike section 111 of each of the plurality of staples 10 includes a body section 115 extending from the stop portion 40 and an enlarged head 116 connected to the body section 115. The enlarged head 116 projects laterally relative to the body section 115, which enhances firm engagement of the spike section 111 in the mounting base. An inner side of the spike section 111 of each of the plurality of staples 10 includes a rib 117 extending on the body section 115 and the enlarged head 116, which reinforces the structural strength of the staple 10 and facilitates insertion of the spike section 111 into the mounting base. The two leg portions 11 define a width direction W, and a height direction H is defined as to be perpendicular to the width direction W. The crown portion 12 of each of the plurality of staples 10 has a height D extending in the height direction H larger than a width of the leg portion 11 extending in the width direction W, which reinforces the structural strength of the staple 10 and facilitates insertion of the spike section 111 into the mounting base.

In this embodiment, the plurality of staples 10 are distanced equidistantly by at least one of the first connection portion 20 and the second connection portion 30, preventing the striker of the stapler 50 from striking neighboring two staples of the plurality of staples 10 at once.
