Technical Field

The invention relates to a cable tie.

Background

At present, when wires are fixed by using a wire binding belt, most of the wires are operated manually, and the strength and the standard of each worker are different, so that the binding tightness degree of the wire binding belt is different. If the binding belt is tightly bound, the external insulation material of the wire rod is pressed, and the thickness of the external insulation material of the wire rod is further thinned. When the bound power supply wire rod is a power supply wire rod, the power supply wire rod can generate heat when large current flows through the power supply wire rod, so that the external insulating material of the wire rod is heated. At this time, the protective effect provided by the thinned outer insulating material due to the over-tightening of the binding is reduced.

Disclosure of Invention

The invention aims at a cable tie, which can avoid the problem that the cable tie is bound too tightly.

According to an embodiment of the present invention, a cable tie includes a tie body, a seat body, a restriction member, and a control member. The belt body has a contact side. The seat body is connected to the first end of the belt body and is provided with a through hole. The limiting piece is connected to the base body and is located in the through hole. The control piece is provided with a connecting part, an intrusion part far away from the connecting part and a pressing part, wherein the connecting part is connected with the seat body. When the belt body passes through the through hole, the contact side defines a wire harness area for accommodating the bundled object, and the protruding part protrudes into the wire harness area. When the object pushes the protrusion portion outward of the wire harness area, the pressing portion presses the restriction member to restrict the movement of the strap body.

In an embodiment according to the invention, the cable tie is integrally formed.

In the embodiment according to the present invention, the pressing portion is kept away from the restricting member when the protruding portion is not pushed by the object to be bundled.

In an embodiment according to the present invention, the belt body further has a plurality of first one-way teeth on the contact side, and the restricting member has at least one second one-way tooth that cooperates with the first one-way teeth to restrict the movement of the belt body toward a direction in which the harness area is expanded.

In an embodiment in accordance with the invention, the limiter has a plurality of second unidirectional teeth.

According to an embodiment of the present invention, a cable tie includes a tie body, a seat body, a restriction member, and a control member. The belt body has a contact side. The seat body is connected to the first end of the belt body and is provided with a through hole. The limiting piece is connected to the base body and is located in the through hole. The control piece is provided with a connecting part, an intrusion part far away from the connecting part and a pressing part, wherein the connecting part is connected with the seat body. The pressing part keeps a distance from the limiting part, and the control part can rotate to press the limiting part through the pressing part. When the belt body passes through the through hole, the contact side defines a wire harness area for accommodating the bundled object, and the protruding part protrudes into the wire harness area.

In an embodiment according to the invention, the cable tie is integrally formed.

In an embodiment according to the present invention, the belt body further has a plurality of first one-way teeth on the contact side, and the restricting member has at least a second one-way tooth that cooperates with the first one-way teeth to restrict the movement of the belt body toward a direction in which the harness area is expanded.

In an embodiment in accordance with the invention, the limiter has a plurality of second unidirectional teeth.

In view of the above, in the cable tie of the present invention, when the protruding portion is pushed by the object to be bundled, the pressing portion presses the restriction member to restrict the movement of the tie body.

Detailed Description

Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.

Fig. 1 is a perspective view of a cable tie according to an embodiment of the present invention, and fig. 2 is a perspective view of another perspective view of the cable tie of fig. 1. Referring to fig. 1 and fig. 2, the cable tie 100 of the present embodiment includes a tie body 110, a seat body 120, a limiting member 130, and a control member 140. The tape 110 has a contact side 112. The base 120 is connected to a first end 114 of the belt 110, and the base 120 has a through hole 122. The limiting member 130 is connected to the housing 120 and located in the through hole 122.

Fig. 3 is a partial sectional view of the harness of fig. 1 in a state of being bundled, and fig. 4 and 5 are sectional views of a control member of the harness of fig. 1 before and after actuation. Referring to fig. 3 and 4, the control member 140 has a connecting portion 142, and an inward protruding portion 144 and a pressing portion 146 far from the connecting portion 142. The connecting portion 142 is connected to the housing 120. The contact side 112 defines a cable zone R10 for receiving an object 50 to be bundled when the strap 110 is inserted through the aperture 122. In other words, when the cable tie 100 is in the cable-bound state, the strap 110 surrounds the object 50, and the area surrounded by the strap 110 is the cable-bound area R10. The contact side 112 is a side of the tape body 110 for contacting the object 50 to be bundled.

As seen from fig. 4, when no external force is applied, the protruding portion 144 protrudes into the harness portion R10, and the pressing portion 146 is kept away from the restriction member 130. In this state, when the tape 110 moves in the through hole 122, the limiting member 130 may be driven to rotate repeatedly along the direction a12 and the opposite direction, and the rotation of the limiting member 130 is not limited.

Referring to fig. 5, during tightening, when the object 50 pushes the protrusion portion 144 outward of the wire-tightening region R10 along the direction a16, the control member 140 rotates along the direction a14, and the pressing portion 146 moves along the direction a 18. When the pressing portion 146 moves along the direction a18, the distance between the pressing portion 146 and the limiting member 130 is changed, and the pressing portion 146 presses the limiting member 130 to contact the strap 110 to be unable to rotate, so that the limiting member 130 limits the movement of the strap 110.

As can be seen from the above, when the object 50 pushes the protruding portion 144 outward of the wire harness region R10, the problem of binding too tightly occurs if the wire harness region R10 continues to contract. However, since the pressing portion 146 of the control member 140 presses the limiting member 130 to limit the movement of the strap 110, the wire harness R10 can be prevented from being further shrunk, and the problem of over-tight binding can be avoided.

In the present embodiment, the cable tie 100 is integrally formed. For example, the cable tie 100 may be formed by injection molding using a plastic material, thereby saving assembly time and cost when not integrally molded. However, the present invention is not limited to the cable tie 100 being integrally formed.

In the present embodiment, the pressing portion 146 is spaced from the limiting member 130 when the protruding portion 144 is not pushed by the object 50. However, in other embodiments, it is also possible that the pressing portion 146 just contacts but does not push the limiting member 130 when the protruding portion 144 is not pushed by the object 50. By designing the distance between the pressing portion 146 and the limiting member 130, the degree of tightening for limiting the movement of the strap 110 can be adjusted.

In this embodiment, the strap body 110 further has a plurality of first unidirectional teeth 116 on the contact side 112, and the restraining member 130 has at least one second unidirectional tooth 132. When the tape 110 moves in the through hole 122 to shrink the wire binding area R10, the first one-way tooth 116 will move the second one-way tooth 132 to rotate the limiting member 130. The second one-way tooth 132 can cooperate with the first one-way tooth 116 to restrict the movement of the belt body 110 toward the direction of expanding the harness region R10. In other words, when the tape body 110 intends to move reversely in the through hole 122 to expand the cable-restraining zone R10, the first one-way tooth 116 and the second one-way tooth 132 are engaged with each other to prevent the tape body 110 from moving, thereby preventing the cable-restraining tape 100 from being loosened. Here, the number of the second unidirectional teeth 132 may be plural, but the number of the second unidirectional teeth 132 may be single in other embodiments.

As described above, in the cable tie of the present invention, if the over-tightening situation occurs, the protruding portion is pushed by the object to be tied, and the pressing portion presses the restriction member to restrict the movement of the strap body. Therefore, the movement of the belt body can be automatically limited by the cable tie of the invention without manual judgment, so that the cable tie is prevented from being bound too tightly, and the function of protecting the bound object from being damaged is achieved.
