Description

Connector for screw fastening

[0001] The present invention relates to a screw fastening connector, and more particularly, to a screw fastening connector that enables objects to be fastened with screws to be easily fastened with screws when the objects to be fastened with screws are spaced apart from each other.

[0002] In the process of electrical installation such as an outlet, as illustrated in Fig. 1, when the first coupling object (210) is embedded in a concrete wall (C), the second coupling object (220) is covered over the first coupling object (210) and the first coupling object (210) and the second coupling object (220) are coupled by a fastening screw (310). For reference, although the following description assumes that the first coupling object (210) is an outlet box and the second coupling object (220) is an outlet cover, the specific types of the first coupling object and the second coupling object are not limited.

[0003] In many cases, as illustrated in FIG. 2, an exterior material (F) having a predetermined thickness can be constructed on a concrete wall (C). In this case, the second joining object (220), i.e., the outlet cover, does not directly contact the first joining object (210), i.e., the outlet box, and is joined in a state spaced apart by the thickness of the exterior material (F) as illustrated in FIG. 3. In order to easily illustrate the reference joining structure, the exterior material (F) portion is indicated by a dotted line in FIG. 3 and the following drawings. In this case, a typical fastening screw (310) cannot be used as is, but a fastening screw (310) having a considerably long screw portion is used. However, the process of allowing the end of the fastening screw (310) to be inserted into the first fastening screw joint (211) formed on the first joining object (210) was not easy for the worker. In particular, as the length of the fastening screw (310) increases, the end of the fastening screw (310) often touches the wire (B) that has entered the interior of the first coupling object (210), resulting in damage to the wire (B).

[0004] The present invention is intended to solve the problems of the prior art as described above, and provides a screw fastening connector that enables the use (310) of a cover fastening screw of a normal length even when the first fastening object (210) and the second fastening object (220) must be fastened in a spaced state due to the use of a thick outer material (F).

[0005] Furthermore, the purpose is to prevent the worker from having difficulty accurately inserting the end of the fastening screw into the first fastening screw joint (211) of the first joining object (210) when the outer material (F) becomes thicker, and to prevent the end of the fastening screw (310) from touching the wire (B) installed inside the first joining object (210), thereby causing damage to the wire.

[0006] The present invention relates to a screw fastening connector for screw-fastening a first coupling object and a second coupling object that are spaced apart from each other, and is characterized by including: a vertical frame (110); a base portion (140) formed at one end of the vertical frame (110) and capable of being fastened to a first fastening screw-fastening portion (211) of the first coupling object by a first screw (151); and a screw receiving portion (120) formed at the other end of the vertical frame (110) and having a female thread (121) formed at a predetermined portion so as to be fastened to a second fastening screw-fastening portion (221) of the second coupling object by a second screw (152).

[0007] In using the screw fastening connector according to the present invention, the process of first fastening the base part (140) to the first fastening screw joint part (211) by the first screw (151) is performed, and then the process of fastening the second fastening screw joint part (221) to the screw receiving part (120) by the second screw (152) is performed.

[0008] In addition, the screw receiving portion (120) is formed in a cone shape with a wide upper end and a narrow lower end, and is characterized in that a female screw thread (121) that can be fastened with the second screw is formed at the top of the cone.

[0009] Furthermore, a part of the screw receiving portion (120) is characterized in that a handle portion (130) is formed that can be held by a worker with a hand or a tool.

[0010] The screw fastening connector according to the present invention includes a screw receiving portion in the shape of a cone with an enlarged top, and a female spur is formed near the top of the cone, so that a worker can easily insert the end of a screw into the screw receiving portion, thereby increasing the efficiency of assembly work.

[0018] Hereinafter, the overall configuration of a screw-fastening connector according to the present invention will be described with reference to the drawings. Specific structural and functional descriptions presented in the embodiments of the present invention are merely illustrative for the purpose of explaining embodiments according to the concept of the present invention, and embodiments according to the concept of the present invention may be implemented in various forms. Furthermore, the present invention should not be construed as being limited to the embodiments described in this specification, but should be understood to include all modifications, equivalents, and substitutes included within the spirit and technical scope of the present invention.

[0019] FIG. 4 illustrates the overall shape of a screw fastening connector according to a first embodiment of the present invention. The base portion (140) is an element that is supported by being in contact with the first fastening screw joint portion (211) of the first coupling object (210). A fixing through-hole (142) into which a screw can be coupled is formed in the base portion (140), and an anti-rotation member (141) is formed on one side of the base portion (140). A first screw (151) can pass through the through-hole (142) of the base portion (141) to couple the base portion (140) and the first fastening screw joint portion (211) of the first coupling object (210) to each other. In addition, the anti-rotation member (141) is supported by being in contact with one surface of the first fastening screw joint portion (211), thereby preventing the screw fastening connector from rotating at all during the rotation process of the first screw.

[0020] A vertical frame (110) is formed on one side of the base portion (141), and the length of the vertical frame (110) is determined to be shorter than the thickness of a typical exterior material (F). In addition, a screw receiving portion (120) may be formed on the upper surface of the vertical frame (110), and the screw receiving portion (120) has a female screw thread (121) formed therein to be combined with a second screw (152) for combining a second coupling target (220). Preferably, the second screw (152) is formed in a cone shape with an open upper end so that the end thereof can be easily fitted into the portion where the female screw thread (121) is formed. That is, the upper end of the screw receiving portion (120) may be formed wide, while the lower end may be formed narrow, and the female screw thread (121) may be formed on the narrow portion of the lower end (the apex of the cone). Preferably, a handle portion (130) may be formed in a predetermined portion of the screw receiving portion (120) so that the worker can easily hold it by hand during the process of fixing the base portion (140) to the first coupling target (210).

[0021] Fig. 5 illustrates a process of fixing a screw fastening connector (100) according to a first embodiment of the present invention to a first fastening screw joint (211) of a first coupling target (210). In a state where the base portion (140) of the screw fastening connector (100) is supported by the first fastening screw joint (211) of the first coupling target (210), the base portion (140) and the fastening screw joint (211) are coupled by a first screw (151). At this time, the fastening tool (D) for rotating the first screw (151), i.e., the driver, may interfere with the screw receiving portion (120) when placed vertically, and therefore, may be tilted at a predetermined angle (5 to 45°) rather than vertically when working. At this time, since the rotation prevention device (141) is in contact with the side of the first fastening screw joint (211) of the first coupling target (210), the screw fastening connector (100) is prevented from rotating as a whole during the process of working with the fastening hole (D). Fig. 6 illustrates a state in which the screw fastening connector (100) is fixed to the first fastening screw joint (211) of the first coupling target (210) by the first screw (151).

[0022] Fig. 7 illustrates a process of fixing a second coupling object (220) while the screw fastening connector (100) is fixed to a first coupling object (210). The second coupling object (220) is placed at a distance from the first coupling object (210) by the thickness of the exterior material (F), and the second coupling object (220) is fixed to the screw fastening connector (100) by a second screw (152) penetrating the second coupling screw joint portion (221) of the second coupling object (220). Here, the length of the second screw (152) should be formed longer than the length from the second coupling object (220) to the female thread (121) of the screw receiving portion (120). Since the screw receiving portion (120) is formed in a cone shape with a wide top, the worker can make the end of the second screw (152) contact the female thread (121) of the screw receiving portion (120) without much effort. Fig. 8 illustrates a state in which the work process of Fig. 7 is completed and the second joining object (220) is joined to the screw fastening connector (100) by the second screw (152).

[0023] Fig. 9 illustrates the configuration of a screw-fastening connector according to a second embodiment of the present invention. The configuration of the handle portion (130) differs from that of the first embodiment. In the second embodiment, a handle portion cutting groove (131) is formed in the handle portion (130). If the handle portion (130) interferes with surrounding elements, the worker can remove a portion of the handle portion (130) by bending the handle portion (130) at the cutting groove (131).

[0024] Figure 10 illustrates the configuration of a screw-fastening connector according to a third embodiment of the present invention. In this third embodiment, the shape of the screw receiving portion (120) is modified. It is characterized by the lower end of the cone-shaped screw receiving portion being formed into a long, cylindrical shape. By following the above embodiment, the length of the female screw thread (121) can be increased.

[0025] FIG. 11 illustrates the configuration of a screw fastening connector according to a fourth embodiment of the present invention. While the first to third embodiments have structures that are easy to manufacture by a sheet metal process, the fourth embodiment has a structure that is easy to manufacture by injection molding, and since each element and principle are the same as those of the screw fastening connectors according to the first to third embodiments, a detailed description thereof will be omitted.

[0026] The present invention relates to an industrially applicable screw fastening connector, and has industrial applicability.
