Description

Technical Field

[0001] The utility model relates to the technical field of crystal heads, in particular to a quick-installation crystal head structure. Background Art

[0002] The crystal head is the port connector for electronic devices to be connected to the network by wire. When connecting the network cable to the existing crystal head, the 8 sub-wires are inserted into the corresponding wire grooves in the crystal head, and then the network cable is fixed in the crystal head with the help of special tools. At the same time, the copper sheet is inserted into the sub-wire and contacts the sub-wire core.

[0003] In this type of crystal head, the wire slot is located at the head of the crystal head. After the 8 sub-wires are inserted into the crystal head from the tail, the ends of the sub-wires are not easy to align side by side, so it is not easy to correspond to the wire slots one by one. It may take repeated attempts to insert them, which is very inconvenient, time-consuming and laborious. In addition, the installation and connection of the crystal head and the network cable requires the use of special tools. If you don't have the tool, you can't install the crystal head, which makes the crystal head very inconvenient to use. Especially for scattered users, it is not economical to buy special tools when they are rarely installed and not often used. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a quick installation crystal head structure.

[0005] The technical solution of this utility model is as follows:

[0006] A quick-install crystal head structure, comprising a core body and a protective shell, wherein the inner cavity of the protective shell opens backwards, the core body is inserted from the rear end of the protective shell and its shape matches the inner cavity of the protective shell;

[0007] The core body includes an upper plate body and a lower plate body that are buckled with each other. A plurality of wire grooves are provided between the upper plate body and the lower plate body, which penetrate the front and rear ends of the core body. The wire grooves are arranged at intervals along the width direction of the core body and are used to clamp the sub-wires of the network cable.

[0008] A downward guide hole is provided at the bottom near the front end of the wire trough, in which a signal guide is inserted, and the cross section of the signal guide matches the cross section of the guide hole. The upper and lower sides of the signal guide are exposed from the upper and lower sides of the lower plate respectively, and the upper side can contact the wire core in the sub-wire, and the lower side is used to contact the connection contact pins of the electronic device port to be connected;

[0009] A plurality of sliding grooves are provided at the lower front end of the protective shell corresponding to the plurality of signal guides. The openings of the sliding grooves face downward and forward, exposing the lower edges of the signal guides. The connecting contacts of the electronic device port slide into the sliding grooves and contact the signal guides, thereby completing the connection of the network signal.

[0010] The above scheme clamps the sub-wire of the network cable in the wire slot, and uses an ordinary tool to remove a part of the insulation skin at the front end of the sub-wire in advance to expose the wire core. During the corresponding buckling process of the mountain plate body and the lower plate body, the upper side of the signal guide plate first contacts the wire core, and is finally pushed to the bottom to expose the lower plate body. The core body is inserted into the protective shell to complete the connection and installation of the crystal head and the network cable. The entire installation process only uses an ordinary tool and can be completed without professional tools, which greatly facilitates the use of the crystal head and meets the needs of individual users.

[0011] In the present application, the signal guide is a rectangular sheet, preferably a copper sheet, with locking bumps on the upper front and rear ends to limit the distance the signal guide can move downward in the guide hole, while ensuring that the upper edge of the signal guide can contact the core of the network cable.

[0012] In order to enable the signal guide plate to contact the wire core, the upper edge of the signal guide plate should not be lower than the upper surface of the lower plate body.

[0013] Correspondingly, the lower edge of the signal guide protrudes from the lower surface of the lower plate body to facilitate connection with the port of the electronic device.

[0014] In the present application, the cross-section of the wire trough is circular to facilitate fixing and clamping the sub-wires.

[0015] The wire groove comprises an upper wire groove opened on the upper plate body and a lower wire groove opened on the lower plate body, and the corresponding central angle of the upper wire groove is greater than the corresponding central angle of the lower wire groove, so that the sub-wires can be clamped when the sub-wires are arranged.

[0016] Preferably, the center angle corresponding to the cross section of the upper wire groove is between 180 and 220 degrees, so that a sufficient area of ​​the wire core can be exposed while the insulation of the sub-wire is cut off.

[0017] Furthermore, each wire trough is provided with a slot at the top near the front end, and the radius of the slot is equal to the radius of the wire trough. When installing the sub-wire, the head of the sub-wire is inserted into the slot, and then the sub-wire is straightened along the wire trough, which facilitates the installation of the sub-wire.

[0018] In order to facilitate the insertion of the core into the protective shell, the rear ends of the upper and lower plates extend backward with a gripping part, which forms a rectangular cavity after being buckled and is connected to the wire slot of the core. The rear ends of the two gripping parts are provided with a semicircular clamping hole at the splicing position. The diameter of the two semicircular clamping holes is the same as the diameter of the network cable, and they clamp and fix the network cable together.

[0019] In order to prevent the core from falling out of the protective shell, a fixing groove is provided at the front end of the upper surface of the upper plate, and a through hole is provided at the top of the protective shell corresponding to the fixing groove. The crystal head structure also includes a locking piece, the front end of which passes through the through hole and is inserted into the fixing groove for fixing, and the rear end extends obliquely backward and upward. The locking piece is also used to clamp the crystal head in the port of the electronic device.

[0020] The utility model provides a quick installation crystal head structure, which can complete the connection and installation of the crystal head and the network cable by only using an ordinary tool, without the need for special tools, greatly facilitating the use and installation of the crystal head, and also meeting the needs of individual users.

[0028] like Figure 1-Figure 4 As shown, an embodiment of the utility model provides a quick-install crystal head structure, including a core body 1 and a protective shell 2. The protective shell 2 is a rectangular body with its inner cavity opening facing backwards. The core body 1 is inserted from the rear end of the protective shell 2 and its shape matches the inner cavity of the protective shell 2.

[0029] Among them, the core body 1 includes an upper plate body 11 and a lower plate body 12 that are interlocked. In this embodiment, a plurality of recessed grooves (not shown in the figure) are arranged on both sides of the lower surface of the upper plate body 11, and plug-in blocks (not shown in the figure) are arranged on the upper surface of the lower plate body 12 at positions corresponding to the recessed grooves. The plates are interlocked together by plugging, but the present application does not limit the interlocking method.

[0030] A plurality of wire grooves penetrating the front and rear ends of the core body 1 are provided between the opposite surfaces of the upper plate body 11 and the lower plate body 12 . The wire grooves are arranged at intervals along the width direction of the core body 1 and are used to clamp the sub-wires 51 of the network cable 5 .

[0031] In this embodiment, the cross-sections of the upper plate body 11 and the lower plate body 12 are both rectangular and have the same thickness to facilitate material selection and processing.

[0032] Please refer to Figure 4As shown, in this embodiment, there are 8 wire slots, corresponding to the number of sub-wires 51 of the network cable 5, and are evenly arranged along the width direction of the core 1.

[0033] The wire groove includes an upper wire groove 111 opened on the upper plate body 11 and a lower wire groove 121 opened on the lower plate body 12. The upper wire groove 111 and the lower wire groove 121 cooperate with each other to make the cross-section of the wire groove circular, and the diameter of the circle is the same as the diameter of the sub-wire 51, so as to clamp and fix the sub-wire 51.

[0034] Preferably, the central angle of the upper wire groove 111 is greater than the central angle of the lower wire groove 121 , so that the sub-wires 51 can be clamped when the sub-wires 51 are arranged.

[0035] In addition, the solution of this embodiment requires cutting off a portion of the insulation skin at the front end of the sub-wire 51 along the lower surface of the upper plate body 11 to expose the internal wire core 511. Therefore, the central angle corresponding to the cross section of the upper wire groove 111 is preferably between 180 and 220 degrees. The upper wire groove 111 in this angle range can ensure that the insulation skin is cut off while exposing a sufficient area of ​​the wire core 511. In actual use, a small part of the wire core 511 will be cut off to contact with the signal guide plate 3 described below to ensure the effect of signal transmission.

[0036] Please refer to Figure 1-Figure 3 As shown, each lower wire groove 121 is provided with a downward guide hole 122 near the front end, in which a signal guide plate 3 is inserted, and the cross-section of the signal guide plate 3 matches the cross-section of the guide hole 122. The upper and lower edges of the signal guide plate 3 are exposed from the upper and lower surfaces of the lower plate body 12 respectively, and the upper edge can contact the wire core 511 in the sub-wire 51, and the lower edge is used to contact the connecting contact pins of the port of the electronic device to be connected.

[0037] In this embodiment, the signal guide plate 3 is a rectangular sheet whose thickness is greater than or equal to the diameter of the wire core 511 and less than the diameter of the sub-wire 51, and is preferably a copper sheet. The upper parts of the front and rear ends are provided with locking protrusions for locking the downward position when the signal guide plate 3 moves downward, thereby ensuring that the upper edge of the signal guide plate 3 can contact the wire core 511 of the network cable 5.

[0038] In order to make the signal guide plate 3 contact with the wire core 511, the upper side of the signal guide plate 3 is not lower than the upper surface of the lower plate body 12. In this embodiment, the upper side of the signal guide plate 3 can be flush with the upper surface of the lower plate body 12.

[0039] Correspondingly, the lower edge of the signal guide plate 3 protrudes from the lower surface of the lower plate body 12 to facilitate connection with the port of the electronic device.

[0040] A plurality of sliding grooves 21 are provided at the lower front end of the protective shell 2 corresponding to the plurality of signal guide plates 3. The openings of the sliding grooves 21 face downward and forward, exposing the lower edges of the signal guide plates 3. The connecting contacts of the electronic device port slide from the sliding grooves 21 into contact with the signal guide plates 3, thereby completing the connection of the network signal.

[0041] In this embodiment, in order to facilitate the fixing of the sub-wire 51, each upper wire groove 111 is provided with a slot 112 upward near the front end, and the radius of the slot 112 is equal to the radius of the wire groove. When installing the sub-wire 51, the head of the sub-wire 51 is inserted into the slot 112, and then the sub-wire 51 is straightened along the upper wire groove and fixed.

[0042] In order to facilitate the insertion of the core body 1 into the protective shell 2, the rear ends of the upper plate body 11 and the lower plate body 12 are respectively extended with gripping parts, which are buckled together to form a rectangular cavity and communicate with the wire groove of the core body 1. The rear ends of the two gripping parts are provided with semicircular clamping holes at the splicing position, and the diameter of the two semicircular clamping holes is the same as the diameter of the network cable 5, and the network cable 5 is clamped and fixed together.

[0043] In addition, in order to prevent the core 1 from falling out of the protective shell 2, the crystal head structure also includes a detachable locking member 4. A fixing groove 113 is provided in the middle of the front end of the upper surface of the upper plate 11. The protective shell 2 is provided with a through hole 22 above the fixing groove 113. The front end of the locking member 4 is bent downward, inserted into the fixing groove 113 through the through hole 22 and fixed, and the rear end extends obliquely backward and upward. The locking member 4 also has a clamping portion (not shown in the figure) protruding outward on both sides near the front end, which is used to clamp the crystal head structure in the port of the electronic device.

[0044] like Figure 1 As shown, before the network cable 5 is connected, the signal guide sheet 3 is inserted into the guide hole 122 in advance, but the bottom edge thereof is not exposed from the bottom surface of the lower plate body 12;

[0045] Arrange the sub-wires 51 of the network cable 5 in order, insert the heads into the slots 112, and then insert each sub-wire 51 into the corresponding upper wire slot 111, and then use a cutter to remove the insulation of the exposed portion of the front end to expose the wire core 511. At the same time, a portion of the wire core 511 will be cut off so that the exposed surface is flush with the lower surface of the upper plate body 11;

[0046] The upper plate 11 and the lower plate 12 are buckled together. During the buckling process, the upper side of the signal guide sheet 3 first contacts the wire core 511. During the continuous buckling process, the signal guide sheet 3 is squeezed and moves downward in the guide hole 122 until the lower side exposes the lower plate 12. At this time, the wire grooves of the upper plate 11 and the lower plate 12 jointly clamp and fix the sub-wire 51.

[0047] Insert the core 1 into the protective shell 2, and then insert the locking piece 4 to complete the connection and installation of the crystal head and the network cable 5.

[0048] The crystal head structure of the present application only requires common cutting tools during the entire installation process and can be installed without professional tools, which greatly facilitates the use and installation of the crystal head and meets the needs of individual users.
