Description

[Technical Field]

[0001] The present invention relates to connectors, and more particularly to insulation piercing connectors. [Background technology]

[0002] In commonly encountered electrical connectors, the electrical connection between the power or signal cable and the electrical connector is mainly achieved by welding, but in some applications, the electrical connector is provided with a blade or needle configured to pierce the insulating layer covering the electrical wire to make electrical contact with the electrical wire, thereby achieving the electrical connection between the power or signal cable and the electrical connector.

[0003] In commonly encountered insulation piercing connectors, the hardness of the insulation layer means that piercing with a blade or needle requires a considerable amount of time and force, resulting in a high piercing failure rate, and some improvement is therefore needed. Summary of the Invention [Problem to be solved by the invention]

[0004] The present invention provides an insulation piercing connector that contributes to saving time and labor costs and improving piercing accuracy. [Means for solving the problem]

[0005] According to one embodiment of the present invention, an insulation piercing connector is adapted to pierce a cable disposed therein. The insulation piercing connector includes a base and a cover removably and pivotably connected to the base. The base has a cable slot for arranging and accommodating the cable and a pivot groove located on a side of the cable slot. The cover includes a conductive piercing member provided corresponding to the cable slot and a shaft provided corresponding to the pivot groove. The shaft is removably inserted into the pivot groove to form a hinged connection between the cover and the base, and the conductive piercing member is aligned with the cable. When the cover rotates along a first rotation direction to cover the base, the conductive piercing member moves toward the cable to pierce the cable.

[0006] In an insulation piercing connector according to one embodiment of the present invention, the base includes a base snap opposite the pivot groove, and the cover further includes a cover snap opposite the shaft. The cover snap is aligned with the base snap. When the cover rotates along a first rotation direction to cover the base, the cover snap moves toward the base snap to engage with it.

[0007] In an insulating piercing connector according to one embodiment of the present invention, the conductive piercing member is located between the cover snap and the shaft.

[0008] In an insulating piercing connector according to one embodiment of the present invention, the distance between the conductive piercing member and the cover snap is longer than the distance between the conductive piercing member and the shaft.

[0009] In one embodiment of the insulation piercing connector of the present invention, the base further has a top edge portion facing the cover, a first side edge portion, and a second side edge portion, the first side edge portion and the second side edge portion being connected to two opposite ends of the top edge portion, and the cable slot extends from the first side edge portion to the second side edge portion and is recessed from the top edge portion.

[0010] In an insulation piercing connector according to one embodiment of the present invention, the pivot groove is located adjacent to the first side edge and recessed from the top side edge, and the base snap is located on the second side edge.

[0011] In one embodiment of the insulation piercing connector of the present invention, the base includes a first pivot portion and a second pivot portion opposite the first pivot portion, the first pivot portion and the second pivot portion being positioned in a pivot groove, the first pivot portion being positioned at an opening of the pivot groove and the second pivot portion being positioned at a bottom of the pivot groove, and the shaft is rotatably sandwiched between the first pivot portion and the second pivot portion.

[0012] In one embodiment of the insulation piercing connector of the present invention, the first pivot part has a concave arc surface facing the bottom of the pivot groove, and the second pivot part has an inclined surface facing the opening of the pivot groove, and the shaft rotatably abuts against the concave arc surface and the inclined surface.

[0013] In an insulation piercing connector according to one embodiment of the present invention, the inner wall of the pivot groove is located on the sides of the first pivot portion and the second pivot portion, and the cover further includes a shaft base from which a shaft protrudes, the shaft base abutting against the inner wall.

[0014] In an insulation piercing connector according to one embodiment of the present invention, a shaft positioning space is defined between a first pivot part and a second pivot part. When the cover rotates in a first rotation direction to cover the base, the shaft is inserted into the pivot groove and guided by the second pivot part to move into the shaft positioning space. When the cover rotates in a second rotation direction opposite to the first rotation direction to remove from the base, the shaft base presses against the inner wall to drive the shaft to move out of the shaft positioning space. [Effects of the Invention]

[0015] Based on the above, in an insulation piercing connector according to an embodiment of the present invention, the cover is detachably and rotatably connected to the base. Specifically, a hinged connection formed between the cover and the base can serve as a fulcrum, and the cover is adapted to rotate around the fulcrum to cover the base so as to allow the conductive piercing member to pierce the insulation layer of the cable. Because the resistance arm formed between the fulcrum and the conductive piercing member is less than the effort arm, less force or effort is required to press the conductive piercing member to pierce the insulation layer of the cable, which saves time and labor costs and improves piercing accuracy.

[0016] To make the above easier to understand, several embodiments will be described in detail below with reference to the drawings. [Brief explanation of the drawings]

[0019] Reference will now be made in detail to the exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.

[0020] Fig. 1A is a schematic diagram of an insulation piercing type connector according to one embodiment of the present invention. Fig. 1B is an exploded view of the insulation piercing type connector of Fig. 1A. Fig. 1C is a top view of the insulation piercing type connector of Fig. 1A. Referring to Figs. 1A to 1C, in this embodiment, the insulation piercing type connector 100 includes a base 110 and a cover 120, the base 110 having at least a cable slot 111, and the cable slot 111 is configured to position and accommodate multiple cables 10.

[0021] The cover 120 is detachably and rotatably connected to the base 110 and includes a plurality of conductive piercing members 121 protruding from a bottom 121 facing the base 110. Specifically, the conductive piercing members 121 may be a plurality of conductive blades or a plurality of conductive needles provided corresponding to the cable slots 111. The end of the movement path of each conductive piercing member 121 is located in the cable slot 111. In this manner, when the cover 120 is rotated to cover the base 110, the conductive piercing members 121 move toward the cable slots 111 and are inserted into the cable slots 111 to pierce the cables 10 placed in the cable slots 111, thereby achieving an electrical connection between the cables 10 and the insulation piercing connector 100.

[0022] 2A to 2C are cross-sectional views taken along the cross-sectional line AA in FIG. 1C, illustrating the rotation of the cover. Referring to FIG. 1B and 2A to 2C, the base 110 has a pivot groove 112 located on the side of the cable slot 111, and the cover 120 includes a shaft 122 and a shaft base 123 provided corresponding to the pivot groove 112. In detail, the pivot groove 112 is configured to position and accommodate the shaft base 123 and the shaft 122 protruding from the shaft base 123, thereby forming a detachable hinge connection between the cover 120 and the base 110.

[0023] For example, the base 110 may be provided with two cable slots 111 that are parallel to each other, and the pivot groove 112 is located between the two cable slots 111. Meanwhile, the cover 120 may be provided with at least four conductive puncture members 121, and each cable slot 111 may be aligned with at least two of the conductive puncture members 121.

[0024] 2A to 2C, during the process of attaching the cover 120, the shaft base 123 and the shaft 122 protruding from the shaft base 123 are aligned with the pivot groove 112 and inserted into the pivot groove 112 to form a hinge connection between the cover 120 and the base 110. After that, the cover 120 can be rotated along a first rotation direction R1 to cover the base 110.

[0025] In this embodiment, the base 110 includes a base snap 113 opposite the pivot groove 112, and the cover 120 further includes a cover snap 124 opposite the shaft 122. Specifically, the cover snap 124 is aligned with the base snap 113, and the end of the movement path of the cover snap 124 is located at the base snap 113. When the cover 120 rotates along the first rotation direction R1 to cover the base 110, the cover snap 124 moves toward the base snap 113 to engage with the base snap 113. For example, the cover snap 124 and the base snap 113 may be a combination of a hook and a buckle.

[0026] When the cover 120 is fixed to the base 110 by the engagement formed between the cover snap 124 and the base snap 113, the cover 120 cannot rotate along a second rotation direction R2 opposite to the first rotation direction R1, thereby preventing the cover 120 from accidentally coming off the base 110, which ensures an electrical connection between the cable 10 and the insulating piercing connector 100.

[0027] 1B and 2B, the conductive puncturing members 121 are located between the cover snaps 124 and the shaft 122, and a distance D1 between one of the conductive puncturing members 121 and the cover snaps 124 is longer than a distance D2 between one of the conductive puncturing members 121 and the shaft 122. That is, the conductive puncturing members 121 are disposed closer to the shaft 122 than the cover snaps 124.

[0028] As shown in FIGS. 1B and 2A, the base 110 has an upper side portion 114 facing the cover 120, a first side portion 115, and a second side portion 116. The first side portion 115 and the second side portion 116 are connected to two opposite ends of the upper side 114, and the cable slot 111 extends from the first side portion 115 to the second side portion 116 and is recessed from the upper side portion 114. On the other hand, the pivot groove 112 is located adjacent to the first side portion 115 and is recessed from the upper side portion 114, and the base snap 113 is located on the second side portion 116.

[0029] FIGS. 3A to 3C are cross-sectional views taken along the section line B-B of FIG. 1C, which represent the rotation of the cover. Referring to FIGS. 1B and 2A to 2C or FIGS. 3A to 3C, when a hinge connection between the cover 120 and the base 110 is formed, the conductive piercing member 121 is aligned with the cable 10 disposed in the cable slot 111. As shown in FIGS. 2B, 2C, 3B, and 3C, in the process of the cover 120 rotating along the first rotation direction R1 to cover the base 110, the conductive piercing member 121 moves toward the cable slot 111 and is inserted into the cable slot 111 to pierce the cable 10 disposed in the cable slot 111, thereby achieving an electrical connection between the cable 10 and the insulation piercing connector 100.

[0030] Specifically, each cable 10 includes a wire 11 and an insulating layer 12 covering the wire 11. Each conductive piercing member 121 pierces the corresponding insulating layer 12, so that when the cover 120 rotates to cover the base 110, it is in electrical contact with the corresponding wire 11. Further, when each conductive piercing member 121 pierces the corresponding insulating layer 12 to be in electrical contact with the corresponding wire 11, the cover 120 is fixed to the base 110 by an engagement formed between the cover snap 124 and the base snap 113, thereby preventing the cover 120 from rotating so as to accidentally come off the base 110, which ensures the electrical connection between the cable 10 and the insulation piercing connector 100.

[0031] 2B, 2C, 3B, and 3C, the hinge connection formed between the cover 120 and the base 110 may serve as a fulcrum, and the cover 120 is adapted to rotate about the fulcrum along a first rotation direction R1 to cover the base 110. Because the application point arm formed between the fulcrum (e.g., shaft 122) and one of the conductive piercing members 121 is less than the force point arm formed between the fulcrum (e.g., shaft 122) and the cover snap 124, less force or effort is required to press the conductive piercing member 121 to pierce the insulating layer 12 of the cable 10, which saves time and labor costs and improves piercing accuracy.

[0032] 2A to 2C or 3A to 3C, when the engagement formed between the cover snap 124 and the base snap 113 is released, the cover 120 can be rotated along the second rotation direction R2 to easily detach from the base 110, allowing for easy replacement with another cover as needed. In particular, because the application point arm formed between the fulcrum (e.g., shaft 122) and one of the conductive puncturing members 121 is less than the force point arm formed between the fulcrum (e.g., shaft 122) and the cover snap 124, less force or effort is required to pull the conductive puncturing member 121 out of the insulating layer 12 of the cable 10.

[0033] 4A to 4C are cross-sectional views taken along the cross-sectional line CC in FIG. 1C, illustrating the rotation of the cover. As shown in FIGS. 1B and 4A, in this embodiment, the base 110 further includes a first pivot portion 101 and a second pivot portion 102 opposite the first pivot portion 101, and the first pivot portion 101 and the second pivot portion 102 are positioned in a pivot groove 112. The first pivot portion 101 is positioned at an opening 112a of the pivot groove 112, and the second pivot portion 102 is positioned at a bottom 112b of the pivot groove 112. As shown in FIGS. 4B and 4C, when the hinge connection between the cover 110 and the base 110 is formed, the shaft 122 is rotatably sandwiched between the first pivot portion 101 and the second pivot portion 102.

[0034] 1B and 4A, the first pivot part 101 has a concave arcuate surface 101a facing the bottom 112b of the pivot groove 112, and the second pivot part 102 has an inclined surface 102a facing the opening 112a of the pivot groove 112. In detail, a shaft positioning space 103 is defined between the first pivot part 101 and the second pivot part 102, and more particularly, between the concave arcuate surface 101a and the inclined surface 102a. As shown in FIGS. 4B and 4C, when the hinge connection between the cover 120 and the base 110 is formed, the shaft 122 rotatably abuts against the concave arcuate surface 101a and the inclined surface 102a and is positioned in the shaft positioning space 103.

[0035] As shown in FIG. 1B , the inner wall 112c of the pivot groove 112 may be located on a side of the first pivot part 101 and the second pivot part 102 and perpendicular to the bottom 112b of the pivot groove 112. As shown in FIGS. 2A , 2B , 4A and 4B , the shaft 122 and the shaft base 123 are first inserted into the pivot groove 112 through the opening 112a. After the shaft 122 and the shaft base 123 are inserted into the pivot groove 112, the shaft 122 comes into contact with the inclined surface 102a. As shown in FIGS. 2B , 2C , 4B and 4C , when the cover 110 is rotated in the first rotation direction R1 to cover the base 110, the shaft 122 is guided by the inclined surface 102a of the second pivot part 102 to move into the shaft positioning space 103, and the shaft base 123 moves toward the inner wall 112c of the pivot groove 112.

[0036] 2C and 4C, the shaft 122 abuts against the concave arcuate surface 101a and the inclined surface 102a and is disposed in the shaft positioning space 103, and the shaft base 123 abuts against the inner wall 112c of the pivot groove 112. As shown in FIGS. 2A to 2C or 4A to 4C, when the cover 110 is rotated in the second rotation direction R2 to be removed from the base 110, the shaft base 123 pushes against the inner wall 112c to drive the shaft 122 to move out of the shaft positioning space 103, thereby separating it from the concave arcuate surface 101a and the inclined surface 102a. Thereafter, the shaft 122 and the shaft base 123 can easily pass through the opening 112a and move out of the pivot groove 112.

[0037] In summary, in an insulation piercing connector according to an embodiment of the present invention, the cover is detachably and pivotably connected to the base. Specifically, a hinged connection formed between the cover and the base can serve as a fulcrum, and the cover is adapted to pivot about the fulcrum to cover the base to allow the conductive piercing members to pierce the insulation layer of the cable. Because the application point arm formed between the fulcrum and one of the conductive piercing members is less than the force point arm, less force or effort is required to press the conductive piercing members to pierce the insulation layer of the cable, which saves time and labor costs and improves piercing accuracy.

[0038] Furthermore, when each conductive piercing member pierces the insulating layer to make electrical contact with the electric wire, the cover is fixed to the base by the engagement formed between the cover snap and the base snap, thereby preventing the cover from being accidentally rotated off the base, which ensures an electrical connection between the cable and the insulation piercing connector. Meanwhile, when the engagement formed between the cover snap and the base snap is released, the cover can be easily rotated off the base, allowing it to be easily replaced with another cover as needed.

[0039] It will be apparent to those skilled in the art that various modifications and variations can be made to the disclosed embodiments without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations provided they come within the scope of the following claims and their equivalents.
