Description

Technical Field

[0001] The utility model relates to the field of communication transmission technology, in particular to a single-pair connector which can easily and labor-savingly press-connect the core wires of a cable to a connector, is easy to assemble, has a small number of parts and a small overall size. Background Art

[0002] Single Pair Ethernet (SPE) is a technology that has flourished in recent years. Unlike previous network communication technologies that used four twisted-pair cables, SPE utilizes a single twisted-pair design. Twisted-pair cable systems are used in industrial and building automation applications to provide power and very low-bandwidth data transmission. One potential benefit of SPE is the ability to retain existing bus cabling installed in buildings, saving the time and cost of purchasing and wiring new cables.

[0003] Therefore, the industry has developed corresponding single-pair Ethernet connectors in response to the single-pair Ethernet technology.

[0004] Existing patents, such as one for a "Connector for a Single Twisted Pair of Conductors," employ a method whereby a terminal is crimped onto each core of a single pair of wires before being inserted into a connector housing. This approach has the disadvantage that the connection between the terminal and the core of a single-pair Ethernet cable requires a tool to clamp, and the number of parts involved is high, making it easy to lose parts.

[0005] Another example is the method used in a patent for a "Contact for a Communication Connector and a Communication Connector." One end of the terminal extends into the connector housing and connects to the connector receptacle, while the other end is a piercing terminal exposed at the rear of the connector housing. When assembled with a single-pair Ethernet cable, the core wires of the single-pair Ethernet cable are placed in the corresponding piercing terminals of the terminal. Then, through an upper cover, the core wires are pressed into the corresponding piercing terminals in a straight-up and straight-down manner. The disadvantage is that when pressing the single-pair Ethernet cable, a tool is still required to press the upper cover onto the connector housing.

[0006] Another example is the method used in a patent for a "communication connector," which utilizes the concept of torque to connect a single-pair Ethernet cable to a plug-in, which is then inserted into the housing of the single-pair Ethernet connector. The disadvantage is that, in order to avoid the space for the spring above the connector to move, and to maintain the space for the spring to move and the space for the cover to press together, the connector as a whole becomes longer, which is not only bulky and takes up space. In addition, this conventional technology sets the shaft at the front end of the cover and fixes the hook at the rear end of the cover. When the cable is bent, the cable will interfere with the hook at the rear end of the cover, causing the cover to be pulled open. Furthermore, this conventional technology also has the problem of a large number of parts and the parts are easy to lose.

[0007] Therefore, how to develop a "single-pair connector" that can easily and labor-savingly crimp the core wire of the cable to the connector, is easy to assemble, has a small number of parts, and has a small overall size is an urgent issue that people in the relevant technical field need to solve.

DETAILED DESCRIPTION

[0030] See also Figure 1 and Figure 2 As shown, the single-pair wire connector 100 provided by the present invention comprises a plug portion 10 and a connection portion 20. The present invention is used to connect a cable 30, such as a single-pair Ethernet cable.

[0031] The plug portion 10 has a first front end 11 and a first rear end 12 opposite to each other parallel to the X-axis direction, a top surface 13 parallel to the XY plane, and a first side surface 14 parallel to the XZ plane.

[0032] The XY plane system is composed of the X-axis direction and the Y-axis direction, and the XZ plane system is composed of the X-axis direction and the Z-axis direction. The X-axis direction, the Y-axis direction and the Z-axis direction are perpendicular to each other.

[0033] A spring 15 is provided on the top surface 13. The spring 15 has a first end 151 and a second end 152. The first end 151 is connected to the top surface 13. The spring 15 extends obliquely away from the XY plane from the first end 151. The second end 152 is a distance D from the top surface 13.

[0034] When a force is applied downwardly to the second end 152 of the spring 15 in a direction parallel to the Z-axis, the second end 152 is forced to move downward. When the force is removed, the second end 152 naturally rebounds and moves upward.

[0035] See also Figure 1 and Figure 2 As shown, the connection portion 20 includes a housing 21 , a plurality of piercing terminal slots 22A, 22B, and a cover 23 .

[0036] The housing 21 has a second front end 211 and a second rear end 212 that are opposite each other and parallel to the X-axis. The second front end 211 is connected to the first rear end 12 of the plug portion 10. The housing 21 has a recessed portion 213. A hollow portion 214 is provided at the second rear end 212 and is parallel to the X-axis and communicates with the recessed portion 213.

[0037] The piercing terminal slots 22A and 22B are disposed in the recessed portion 213. Each piercing terminal slot 22A and 22B houses a piercing terminal 221A and 221B. Each piercing terminal slot 22A and 22B has a notch 222A and 222B that connects to the piercing terminal 221A and 221B. The opening of each notch 222A and 222B is parallel to the Y-axis.

[0038] The cover 23 is pivotally connected to the housing 21. The housing 21 has two pivot holes 25 at the second rear end 212. The two pivot holes 25 are spaced apart and parallel to the Z-axis. The cover 23 has two rotating shafts 231, each of which is pivotally connected to a corresponding pivot hole 25.

[0039] The cover 23 can rotate along the Z-axis and open and close relative to the recessed portion 213 .

[0040] A plurality of wire pressing seats 232A, 232B are provided on the inner side surface 236 of the cover 23 (ie, the surface of the cover 23 facing the recessed portion 213 ). Each wire pressing seat 232A, 232B corresponds to a piercing terminal slot 22A, 22B, respectively.

[0041] Each crimping seat 232A, 232B has a groove 235A, 235B respectively, which is used to prevent the crimping seats 232A, 232B from interfering with the piercing terminals 221A, 221B.

[0042] However, it must be noted that the structural design principle of the wire pressing seats 232A, 232B and the piercing terminal slots 22A, 22B is that when the cover 23 is rotated to abut against the recessed portion 213, each wire pressing seat 232A, 232B can be extended into the piercing terminal slots 22A, 22B parallel to the XY plane, and respectively push each core wire 31, 32 to be embedded in the corresponding piercing terminals 221A, 221B, and the wire pressing seats 232A, 232B do not interfere with the piercing terminals 221A, 221B, so it is not limited to Figure 2 Shape shown.

[0043] The housing 21 has two recesses 216 on the inner sidewall 215 of the recessed portion 213. The two recesses 216 are spaced apart and parallel to the Z-axis. The cover 23 has two protrusions 233 on the side 234 opposite the rotation axis 231. When the cover 23 is rotated to abut against the recessed portion 213, the corresponding recesses 216 and protrusions 233 engage with each other.

[0044] The positions of the recess 216 and the protrusion 233 can be interchanged. For example, the recess 216 can be located on the cover 23, while the protrusion 233 can be located on the housing 21. Furthermore, the position and number of the recess 216 and the protrusion 233 are not limited and can be designed based on actual needs. In other words, as long as there are interlocking recesses and protrusions between the housing 21 and the cover 23 to provide a detachable connection between the housing 21 and the cover 23, their position, form, or number are not limited.

[0045] See also Figures 3 to 5 As shown, the combination method of the utility model with the cable is described.

[0046] See also Figure 3 As shown, the cable 30 is passed from the outside of the housing 21 through the hollow portion 214 and then into the housing 21. The cable 30 has two core wires 31 and 32. At this time, the cover 23 is in an open state.

[0047] See also Figure 4 As shown, the core wires 31 and 32 of the cable 30 are respectively passed through the piercing terminal slots 22A and 22B. Then, the cover 23 is rotated around the rotating shaft 231 and closed toward the recessed portion 213 .

[0048] See also Figure 4 and Figure 5 As shown, when the cover 23 is rotated to fit against the recessed portion 213, each wire pressing seat 232A, 232B can extend from the corresponding notch 222A, 222B into the piercing terminal slot 22A, 22B parallel to the XY plane, and push each core wire 31, 32 into the corresponding piercing terminal 221A, 221B. And the convex portion 233 of the cover 23 can be engaged with the concave portion 216 provided at the corresponding position of the housing 21, so that the cover 2 and the housing 21 are combined, as shown in FIG. Figure 5 shown.

[0049] The single-pair connector 100 provided by the present invention utilizes a tool-free crimping method, whereby the cable 30 is directly assembled into the piercing terminals 221A and 221B by rotating the cover 23 with torque.

[0050] See also Figure 2 and Figure 4 As shown, the cover 23 of the present invention is opened and closed at the side, thus avoiding the space for the upper spring 15 to move, thereby avoiding the disadvantage of the conventional technology that the entire connector becomes longer in order to maintain the space for the spring 15 to move and the space for the cover 23 to press together.

[0051] Furthermore, the positioning of the hinge 231 of the cover 23 and the pivot hole 25 of the housing 21, as well as the recess 216 of the housing 21 and the protrusion 233 of the cover 23, differ from conventional designs that place the hinge at the front end of the cover and secure the hook at the rear end. The hinge 231 is located at the rear end of the cover 23 (i.e., the second rear end 212), while the recess 216 of the housing 21 and the protrusion 233 of the cover 23 are located at the front end of the cover 23 (i.e., the side 234). This advantageously prevents the cable 30 from interfering with the hinge 231 or the engagement between the housing 21 and the cover 23 when the cable 30 is bent. This ensures that the cover 23 remains securely attached to the housing 21 and prevents it from being pulled apart.

[0052] See also Figures 6A to 6C , which illustrates the special structural design between the rotating shaft 231 and the pivot hole 25 of the present invention.

[0053] See also Figure 6A As shown, the pivot hole 25 of the housing 21 has a first width W1. Since the pivot hole 25 of this embodiment is a circular hole, the first width W1 is the diameter of the pivot hole 25. The pivot hole 25 and the second rear end 212 of the housing 21 form a connecting portion 251. The connecting portion 251 has a second width W2, which is smaller than the first width W1.

[0054] The rotating shaft 231 of the cover 23 has a wide portion 2311 and a narrow portion 2312. The width of the wide portion 2311 is smaller than the first width W1 and larger than the second width W2. The width of the narrow portion 2312 is smaller than the second width W2. The width direction of the wide portion 2311 is perpendicular to the inner side surface 236 ( Figure 6A As shown, parallel to the X-axis direction), the width directions of the wide portion 2311 and the narrow portion 2312 are perpendicular to each other.

[0055] See also Figure 6A and Figure 6B As shown, since the width of the narrow portion 2312 is smaller than the second width W2 , the cover 23 can enter the pivot hole 25 after passing through the connecting portion 251 in the direction of the narrow portion 2312 toward the housing 21 .

[0056] See also Figure 6C and Figure 6D As shown, the cover 23 is then rotated toward the housing 21 around the rotation shaft 231. Rotating the cover 23 changes the angle between the wide portion 2311 and the narrow portion 2312. Since the width of the wide portion 2311 is smaller than the first width W1 and larger than the second width W2, the rotation shaft 231 cannot escape from the pivot hole 25. This ensures that the cover 23 is securely connected to the housing 21 and prevents the cover 23 from being pulled away from the housing 21 when the cable 30 is pulled.

[0057] See also Figure 7 and Figure 8 As shown, in this embodiment, a housing 40 is provided on the outside of the connection portion 20. The housing 40 is cylindrical and covers the housing 21, the cover 23 and a portion of the cable 30.

[0058] Between the housing 40 and the shell 21, a through portion 41 and a hook 24 are provided, which can engage with each other. For example, in this embodiment, the hook 24 is provided on the shell 21 and the through portion 41 is provided on the housing 40, so that the housing 40 and the shell 21 are detachably connected. Alternatively, the hook 24 can be provided on the housing 40 and the through portion 41 is provided on the shell 21. The position, form, or number of the through portion 41 and the hook 24 are not limited, as long as the housing 40 and the shell 21 can be detachably connected.

[0059] like Figure 8 As shown, the cable 30 is inserted into the wiring portion 20 , the housing 40 is sleeved on the outside of the wiring portion 20 , and the plug portion 10 is protruded from the outside of the housing 40 .

[0060] The shape of the housing 40 is designed according to actual needs and is not limited to Figure 8 The shape shown can cover the connection portion 20 and / or a portion of the cable 30 .

[0061] In summary, the single-pair connector provided by the present invention can easily and labor-savingly crimp the core wires of the cable to the connector. It is easy to assemble, has a small number of parts, and the overall size of the connector is small. The present invention truly combines practicality and functionality.

[0062] Although the present invention has been disclosed above by way of embodiments, they are not intended to limit the present invention. Any person skilled in the art with ordinary knowledge in the relevant technical field should be able to make slight changes and modifications without departing from the spirit and scope of the present invention, and these modifications should still fall within the scope of protection of the present invention.
