Description

Technical Field

[0001] The utility model relates to the field of automotive wire harness fasteners, and particularly relates to an assembly tool for a staple. Background Art

[0002] The wire harness is one of the important components of an automobile. The wire harness is used to provide power supply, ground wire and signal transmission between electrical appliances. With the increase of automobile functions and the widespread application of electronic control technology, there are more and more electrical components, and the wires will become more and more numerous and thicker, especially prominent in new energy or hybrid vehicles. In actual use, the automotive wire harness is fixed by cable ties and brackets, etc. The cable ties need to be fixed to the brackets by staples. Existing screw-in staples are mostly manually installed. The staple has a small diameter, and the leaf teeth have a small force-bearing surface with the fingers. And due to the limitations of the staple structure and forming processability, there are sharp edges on the leaf tooth part of the staple. The sharp edges are extremely easy to hurt the hand during installation. In addition, hand-held installation is laborious, inefficient and easy to damage the leaf teeth of the product. Therefore, improvements are needed. Content of the Utility Model

Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0023] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] Refer Figures 1 to 6 As shown, an assembly tool for a staple includes a tool body 1 with a cylindrical structure. A guide hole 2 is provided at the center of one end of the tool body 1, and a plurality of limiting strips 3 protrude radially along the inner wall of the guide hole 2.

[0025] In this technical solution, the staple includes a head screwed into the bracket and a shank connected to the tie strap. A plurality of groups of leaf teeth are provided on the surface of the shank, and the adjacent groups of leaf teeth are spaced apart to form a spacing groove. The diameter of the guide hole is larger than the outer diameter of the leaf teeth. When the guide hole is sleeved on the shank of the staple, it does not contact the leaves, avoiding damage to the leaves. The limiting strips in the guide hole are snapped into the spacing groove. When the tool body is rotated, the limiting strips drive the staple to rotate together, so as to screw the head of the staple into the corresponding mounting hole of the bracket. During the whole process, the operator's hand does not contact the leaf teeth of the staple, avoiding scratches. The assembly tool for this staple has a simple structure, meets the assembly requirements of the staple, is labor-saving in installation, improves efficiency and safety, and avoids damage to the leaf teeth of the staple during the installation process.

[0026] Exemplarily, refer to Figure 6 As shown, the cylindrical structure is a cylinder.

[0027] In this technical solution, the tool body can be processed from conventional rod materials such as nylon, simplifying the processing technology and reducing the production cost.

[0028] Exemplarily, refer to Figure 6 As shown, a clamping surface (not labeled) is provided on the surface of the tool body 1.

[0029] In this technical solution, the surface of the tooling body is processed with relatively arranged planes or grooves, which is convenient for holding and applying force, and avoids slipping, etc.

[0030] Exemplarily, refer to Figures 1 to 5 As shown, the columnar structure is a prism.

[0031] In this technical solution, the tooling body is made of conventional regular prism materials and does not require machining of the clamping surface. The chamfers are set at the edges of the tooling body to avoid scratching.

[0032] Exemplarily, refer to Figures 1 to 6 As shown, the guiding hole 2 penetrates the tooling body 1.

[0033] In this technical solution, the guiding hole is arranged along the central axis of the tooling body and penetrates the tooling body, which is applicable to staples of different lengths.

[0034] Exemplarily, refer to Figures 2 to 6 As shown, the length direction of the limiting strip 3 extends along the axial direction of the guiding hole 2.

[0035] In this technical solution, the length of the limiting strip is the same as the length of the guiding hole. The limiting strip acts on the sides of all the leaf teeth of the staple at the same time, avoiding deformation caused by uneven force on the leaf teeth of the staple.

[0036] Exemplarily, refer to Figures 2 to 6 As shown, the side surface of the limiting strip 3 close to the central axis of the guiding hole 2 is an arc surface structure.

[0037] In this technical solution, the inner arc surface of the limiting strip corresponds to the guiding conical surface at the end of the staple rod, improving the matching accuracy between the guiding hole and the staple.

[0038] Exemplarily, refer to Figures 2 to 6 As shown, an avoidance surface 4 is arranged on the outer wall of one end of the tooling body 1 close to the entrance side of the guiding hole 2.

[0039] In this technical solution, the outer wall of one end of the tooling body is processed into a conical surface structure. The corresponding end of the guiding hole is used as the entrance side. After the rod of the staple is inserted from the entrance side of the guiding hole, only the flat part of the staple head contacts the corresponding end of the tooling body, avoiding deformation of the staple head during installation.

[0040] In summary, the assembly tooling for this staple has a simple structure, meets the assembly requirements of the staple, is labor-saving during installation, improves efficiency and safety, and avoids damage to the leaf teeth of the staple during the installation process.

[0041] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the element.

[0042] The above are only specific embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
