Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer toFigure 1-7 In an embodiment of the utility model, an anti-swaying industrial shielded crystal head includes a crystal head body 12, one end of the crystal head body 12 is provided with a wire core hole 1, and the other end of the crystal head body 12 is provided with a wire insertion slot 7, and a through slot 8 is provided between the wire core hole 1 and the wire insertion slot 7; a slot 2 is provided at one end of the top of the crystal head body 12 close to the wire insertion slot 7, and a number of slots 2 are evenly spaced, and a terminal 3 is installed inside each slot 2; a pressing sheet 5 is installed at the bottom of the crystal head body 12, and a cushion sleeve 11 is provided at one end of the bottom of the crystal head body 12 close to the wire insertion slot 7, and a shielding layer 4 is wrapped around the outside of the crystal head body 12; two first protrusions 6 are symmetrically provided on both sides of the shielding layer 4, and a second protrusion 10 is provided at the bottom of the shielding layer 4, and two second protrusions 10 are symmetrically provided.

[0029] Specifically, the pressing piece 5 and the crystal head body 12 are both made of plastic, and the end of the pressing piece 5 expands outward and is in a tilted state.

[0030] As a further explanation of this embodiment, a square protrusion is provided in the middle of the pressing sheet 5 for clamping and reinforcing the crystal head body 12 after docking with the terminal interface.

[0031] In this embodiment, the bottom inner wall of the wire core hole 1 is in an arc-shaped structure, and a sloped step structure is provided at one end of the wire core hole 1 close to the through groove 8 .

[0032] To be more specific, the arc-shaped structure can better fit the outer sheath structure of the network cable.

[0033] As a further illustration of this embodiment, the sloped step structure facilitates guiding the wires into the through slot 8 when connecting the network cables.

[0034] In this embodiment, the connection between the slots 2 and the terminals 3 is a sliding connection, and each slot 2 is connected to the inside of a wire insertion slot 7.

[0035] To be more specific, there is a certain damping between slot 2 and terminal 3 , and a special tool is required to fully press terminal 3 into slot 2 when connecting the network cable.

[0036] As a further explanation of this embodiment, when the terminal 3 is fully inserted into the slot 2 , the first plug pin 301 and the second plug pin 302 at the bottom of the terminal 3 will press the metal wire in the corresponding wire slot 7 .

[0037] In this embodiment, the terminal 3 includes a first pin 301 and a second pin 302; two first pins 301 are symmetrically arranged about the vertical axis of the second pin 302, and the bottoms of the first pin 301 and the second pin 302 are both in a "Y" shape.

[0038] Specifically, the width of the first pin 301 is greater than the width of the second pin 302, and there is a certain gap between the first pin 301 and the second pin 302.

[0039] As a further illustration of this embodiment, the "Y" - shaped structure causes the bottoms of the first pin 301 and the second pin 302 to undergo a slight outward - expansion deformation when pressing the metal wire, so as to increase the contact area with the metal wire.

[0040] In this embodiment, there are two groups of the slot grooves 7, and each group of slot grooves 7 is provided with a number of them at equal intervals, and the two groups of slot grooves 7 are arranged in an interlaced manner.

[0041] Specifically, the slot groove 7 is used to accommodate the metal wire.

[0042] As a further illustration of this embodiment, when connecting the network cable, it is necessary to remove the outer skin of the metal wire, arrange them in sequence according to the network - cable connection method of T568A or T568B standard, and cut the ends of the wires flat and then insert them into the slot groove 7.

[0043] In this embodiment, a number of the through - slots 8 are provided at equal intervals, and each through - slot 8 is respectively communicated with a slot groove 7.

[0044] Specifically, the through - slot 8 is designed with a single - layer arrangement.

[0045] As a further illustration of this embodiment, the vertical - section area of the through - slot 8 is larger than the vertical - section area of a single slot groove 7, which is convenient for guiding the inserted metal wire into the interior of the slot groove 7.

[0046] The working principle of the present utility model is as follows: When in use, first remove the outer protective layer of the wire to be connected, cut the ends of the metal wire flat, and remove the rubber outer skin. Then, arrange them in sequence according to the network - cable connection method of T568A or T568B standard. Insert the ends of the wires into the through - slots 8 in sequence. Through the through - slots 8, the ends of the metal wires are sequentially guided into the corresponding slot grooves 7. Then, use a special tool to fully push the terminal 3 into the slot 2, so that the first pin 301 and the second pin 302 press the metal wire in the corresponding slot groove 7. Then, insert the entire crystal - head body 12 into the interface of the terminal. At this time, the terminal 3 is electrically connected to the metal elastic piece in the terminal interface, thereby transmitting data signals. At the same time, the first bump 6, the second bump 10, and the gasket 11 fully fill the gap between the crystal - head body 12 and the terminal interface, greatly reducing the shaking generated when the crystal - head body 12 is in use. At the same time, the pressing piece 5 is elastically snapped inside the terminal interface through its own resilience to prevent the crystal - head body 12 from detaching from the terminal interface.

[0047] For those skilled in the art, by drawing on our idea, any method of changing the volume of the RJ45 connector by increasing the protruding parts, whether in different shapes or position arrangements, will infringe the patent of this utility model.

[0048] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
