Description

Technical Field

[0001] This utility model relates to the field of crystal head, specifically a non-pinning crystal head. Background Technology

[0002] No-crack RJ45 connectors are RJ45 connectors that allow connection of network cables without the need for crimping. Typically, users need to first connect eight network cables into the connector according to a preset connection method, and then press the outer shell to pierce the corresponding network cable's insulation layer to make contact with the inner conductor. Existing one-way opening and closing RJ45 connectors have shielding covers without positioning settings. When opening the shielding cover to install internal components, the upper cover is prone to flipping towards the lower cover, affecting assembly efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a no-crystal connector to solve the technical problems in the background art.

[0004] To achieve the aforementioned objectives, this utility model provides the following technical solution:

[0005] A no-tap RJ45 connector includes a connector body and a shielding shell connected to the right end of the connector body. The shielding shell includes an upper shielding shell and a lower shielding shell. The upper shielding shell is rotatably connected to the connector body, and the lower shielding shell is located below the upper shielding shell and fixedly connected to the connector body. The right end of the connector body has two upwardly extending support plates symmetrically arranged on the left and right sides of the connector body. The upper shielding shell has a pivot shaft rotatably connected to the support plates. The support plates have first mounting holes corresponding to the pivot shaft positions. The upper shielding shell has a first elongated protrusion on the end face near the support plates. The support plate has a first protrusion protruding outward on the end face near the upper shielding shell. Both the first elongated protrusion and the first protrusion are on the right side of the rotating shaft, with the first elongated protrusion below the first protrusion. The upper shielding shell also has a second elongated protrusion on the end face near the support plate. The second elongated protrusion is on the left side of the rotating shaft and above the first elongated protrusion. The support plate has a second protrusion below the first mounting hole. When the upper shielding shell is flipped upward around the axis of the rotating shaft, the first elongated protrusion flips to above the first protrusion, and the second elongated protrusion abuts against the front end of the second protrusion.

[0006] The first bump is an arc-shaped bump structure.

[0007] An IDC terminal block is also installed inside the shielding shell. The front end of the IDC terminal block extends towards the support plate with a strip. The support plate has an elongated slot that penetrates the right end face of the support plate. The strip is inserted into the slot. The bottom end of the slot has an arc-shaped portion. There is a gap between the strip and the bottom end of the slot. This gap forms a first mounting hole for mounting the shaft. The first protrusion is on the strip. The IDC terminal block, the strip, and the first protrusion are an integral structure and are all made of plastic.

[0008] The insert and the sidewall of the slot are elastically mounted, and the inner end face of the slot has a concave contact portion that forms a deformation space with the sidewall of the slot.

[0009] The upper shielding shell has horizontally arranged mounting grooves at its left and right ends. The left side of the mounting groove extends through the left side of the upper shielding shell to form an opening. The opening has a downwardly bent guide groove that communicates with the mounting groove.

[0010] Compared with the prior art, the present invention provides a no-cranking RJ45 connector that is easy and quick to install. The space for the rotating shaft to move is formed by the mutual installation and cooperation of the IDC terminal block and the support plate. The structure is compact and makes the assembly of the RJ45 connector faster. The present application has two protrusions and convex strips on the shielding shell for flipping and positioning, so that the shielding shell can be stably kept in the open state after being flipped upward, which makes it easy for operators to assemble the internal components of the shielding shell and improves the assembly efficiency of the RJ45 connector.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Specific Implementation Example 1: Please refer to Figures 1 to 7 In this embodiment of the invention, a no-tap crystal head includes a crystal head body 1 and a shielding shell 3 connected to the right end of the crystal head body 1. The shielding shell 3 includes an upper shielding shell 4 and a lower shielding shell 5. The upper shielding shell 4 is rotatably connected to the crystal head body 1, and the lower shielding shell 5 is located below the upper shielding shell 4 and fixedly connected to the crystal head body 1. The right end of the crystal head body 1 is provided with two upwardly extending support plates 2, which are symmetrically arranged on the left and right sides of the crystal head body 1. The upper shielding shell 4 has a rotating shaft 403 on both the left and right sides, which is connected to the support plate 5. The support plate 2 is rotatably connected. The left and right rotating shafts on the upper shielding shell 4 are the same as the mounting and positioning structure of the crystal head body 1. The support plate 2 is provided with a first mounting hole 9 corresponding to the position of the rotating shaft 403. The end face of the upper shielding shell 4 near the support plate 2 is provided with a first elongated protrusion 404. The end face of the support plate 2 near the upper shielding shell 4 is provided with a first protruding block 8 protruding outward. In this embodiment, the first protruding block 8 is an arc-shaped protrusion structure. Both the first elongated protrusion 404 and the first protruding block 8 are on the right side of the rotating shaft 403, that is, both are away from the crystal head. On one side of the head body 1, a first elongated ridge 404 is located below the first protrusion 8. The upper shielding shell 4, near the end face of the support plate 2, is also provided with a second elongated ridge 405. The second elongated ridge 405 is located to the left of the rotating shaft 403 and above the first elongated ridge 404. The support plate 2 is provided with a second protrusion 10, located below the first mounting hole 9. In this embodiment, the second protrusion 10 has a rectangular structure. When the upper shielding shell 4 is flipped upwards around the axis of the rotating shaft 403, the first elongated ridge 404 flips to the position of the first protrusion. Above 8, the second elongated protrusion 405 abuts against the front end of the second protrusion 10. That is, the first elongated protrusion 404 and the second elongated protrusion 405 limit the upper shielding shell 4 in two directions. After the upper shielding shell 4 is flipped, the first elongated protrusion 404 abuts against the first protrusion 8 to prevent the upper shielding shell 4 from falling down in the shielding direction. At the same time that the first protrusion 8 and the first elongated protrusion 404 are in contact and abutting, the second elongated protrusion 405 also abuts against the second protrusion 10 to prevent the upper shielding shell 4 from being continuously pressed towards the crystal head body 1.

[0020] An IDC terminal block 6 is also installed inside the shielding housing 3. An insert 7 extends from the front end of the IDC terminal block 6 towards the support plate 2. The support plate 2 has an elongated slot 201 that penetrates the right end face of the support plate 2. The insert 7 is inserted into the slot 201. The bottom end of the slot 201 has an arcuate portion. There is a gap between the insert 7 and the bottom end of the slot 201, which forms a first mounting hole 9 for mounting the rotating shaft 403. In other words, the slot 201 and the insert 7 form a closed mounting space for mounting the rotating shaft 403. In this application, the first protrusion 8 is on the insert 7. The IDC terminal block 6, the insert 7, and the first protrusion 8 are an integral structure and all are made of plastic. The insert 7 and the side wall of the slot 201 have an elastic mounting structure. The inner end face of the slot 201 has a concave contact portion 701 that forms a deformation space with the side wall of the slot 201.

[0021] When the upper shielding shell 1 flips over and presses the first protrusion 8, since the shielding shells are all made of hard metal materials, the structure of the first protrusion 8 and the insert 7 in this embodiment can effectively alleviate the squeezing force between the upper shielding shell 4 and the first protrusion 8, and prevent the upper shielding shell 4 from deforming or other abnormalities after multiple flips and presses.

[0022] In this application, the upper shielding shell 4 has horizontally arranged mounting slots 401 at both its left and right ends. An opening is formed on the left side of the mounting slot 401, penetrating the left side of the upper shielding shell 4. A downwardly bent guide slot 402 communicates with the mounting slot 401 at the opening. The mounting slot 401 is used to insert and install the RJ45 connector onto the positioning strip on the machine base of the device to be installed, achieving stable installation of the entire RJ45 connector and ensuring it is securely plugged into the equipment.

[0023] Compared with the prior art, the present invention provides a no-cranking RJ45 connector that is easy and quick to install. The space for the rotating shaft to move is formed by the mutual installation and cooperation of the IDC terminal block and the support plate. The structure is compact and makes the assembly of the RJ45 connector faster. The present application has two protrusions and convex strips on the shielding shell for flipping and positioning, so that the shielding shell can be stably kept in the open state after being flipped upward, which makes it easy for operators to assemble the internal components of the shielding shell and improves the assembly efficiency of the RJ45 connector.
