Description

Technical Field

[0001] This invention relates to the field of communication module technology, specifically a one-way snap-fit ​​crystal head. Background Technology

[0002] With the rapid development of technology, networks are evolving at an increasingly fast pace. Network cables are categorized into CAT3, CAT5, CAT5E, CAT6, CAT6A, and CAT7; the higher the number, the newer the version, the more advanced the technology, and the higher the bandwidth. The RJ45 connector is a crucial interface component in cable connections, especially network connections. It's a plastic connector that inserts into a device port in a fixed direction and prevents the connector itself from detaching from the port. RJ45 connectors are mainly used to connect network card ports, hubs, switches, and telephones, and are suitable for field termination between devices or in horizontal subsystems. Currently, existing one-way snap-fit ​​RJ45 connectors use a simple pivot connection between the upper and lower pressure caps. This means the pivot is either mounted on the outside of the upper cap or the inside of the lower cap. However, this simple rotating connection structure causes problems during RJ45 connector assembly. When the connector is closed, the internal cable's reaction force can exert a squeezing force on the pivot connection between the lower and upper caps, causing the lower cap to easily detach from the upper cap. This prevents the pressure caps from closing properly, thus affecting the overall assembly efficiency of the RJ45 connector. Summary of the Invention

[0003] The purpose of this invention is to provide a one-way snap-fit ​​crystal head to solve the technical problems in the background art.

[0004] To achieve the aforementioned objectives, the present invention provides the following technical solution:

[0005] A one-way snap-fit ​​crystal connector includes a connector body, an IDC terminal block, and a crimping cover mounted on the rear end of the connector body. The crimping cover includes an upper crimping cover and a lower crimping cover. The lower crimping cover is fixedly connected to the rear end of the connector body. The upper crimping cover is above the lower crimping cover, and its front end is rotatably connected to the lower crimping cover. The IDC terminal block is inside the lower crimping cover, and one end of it is snap-fitted to the lower crimping cover. A first support base and a second support base extend upwards from the left and right sides above the lower crimping cover, respectively. The first and second support bases have identical structures and are symmetrically arranged. The upper crimping cover is rotatably connected to the first and second support bases. A support base has a circular through hole, which is an opening structure that expands and extends towards the IDC terminal block. The left and right inner walls of the upper cover are respectively provided with a rotating shaft. The rotating shaft rotates in the circular through hole. One end of the rotating shaft is fixedly connected to the upper cover, and the other side is provided with a limiting platform protruding outward along its axis. The limiting platform is in the circular through hole. The circular through hole has a limiting groove with an inward structure corresponding to the position of the limiting platform. The front side of the IDC terminal block abuts against the opening of the circular through hole to form a closed movable space between the opening and the circular through hole. The rotating shaft rotates in the movable space.

[0006] The top of the first support base extends toward the IDC terminal block with a first hook. The front side of the IDC terminal block is provided with a second hook toward the first support base. The first hook and the second hook are interlocked. The right side of the IDC terminal block is provided with a second hook of the same structure, which is interlocked with the second support base. The inner end face of the first hook is on the left side of the limiting groove. A step is formed between the inner end face of the first hook and the first support base for supporting the limiting platform.

[0007] The front end face of the IDC terminal block is also provided with a first stop bar. There are two first stop bars, which are symmetrically arranged on the IDC terminal block. The two first stop bars are between two second hooks. The first stop bars are above the limiting groove. The end face of the first stop bar is tangent to the outer end face of the limiting platform.

[0008] The lower and upper pressure covers are equipped with tail sleeves at their rear ends to lock them in place. A tail clip is installed inside the lower pressure cover. The tail clip includes a horizontally positioned positioning plate and a wire holder on the rear side of the positioning plate. The wire holder has a concave lower arc-shaped groove. The rear side of the upper pressure cover has a concave upper arc-shaped groove. The outer sides of the upper and lower arc-shaped grooves are respectively provided with external threads. The upper and lower arc-shaped grooves are combined to form a circular external thread diameter. The external thread diameter is threadedly connected to the tail sleeve.

[0009] The front end of the positioning plate extends toward the plug body and has a third hook. The first mounting part inside the lower cover has a recessed first groove that engages with and limits the third hook. The left and right ends of the front side of the wire holder have first protrusions that protrude outwards. The lower cover has a first insertion hole that engages with the position of the first protrusion.

[0010] The lower part of the front side of the wire holder is also provided with a raised second stop bar, and the rear side of the lower pressure cover is provided with a limiting hole with an opening structure that matches the position of the second stop bar.

[0011] The lower pressure cover includes a first mounting part and a second mounting part. The first mounting part is used to snap-fit ​​with the plug body. The first mounting part has a hollow first receiving cavity. The plug body is inserted into the first receiving cavity. The inner side wall of the first receiving cavity has a raised second protrusion. The plug body has a second insertion hole that engages with the second protrusion. The IDC terminal block is installed in the second mounting part. The rear side of the IDC terminal block has several insertion blocks. The cable holder has a slot that engages with the insertion blocks.

[0012] The circular through hole is located above its opening, and the circular through hole and its opening form an elongated mounting channel, which is inclined toward the IDC terminal block.

[0013] The plug body, IDC terminal block, wire clamp cover, and tail sleeve are all made of plastic.

[0014] Compared with the prior art, the one-way snap-fit ​​crystal head of this application has a compact structure. It uses the IDC terminal block, the first hook and the second hook to form an active space, so that the limiting platform on the rotating shaft is limited to rotate within the active space by the limiting groove. This effectively prevents the upper and lower pressure covers from separating during the assembly. This installation structure makes the connection between the upper and lower pressure covers more stable, and the snap-fit ​​installation connection between each component is fixed, resulting in high overall assembly efficiency of the crystal head.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Specific Implementation Example 1: Please refer to Figures 1 to 13 In this embodiment of the invention, a one-way snap-fit ​​crystal head includes a plug body 1, a PCB board 11, an IDC terminal block 8, and a wire clamping cover 2 installed at the rear end of the plug body 1. The PCB board is installed between the plug body 1 and the wire clamping cover 2, with its front end inserted into the plug body 1 and its rear end inside the wire clamping cover 2. The wire clamping cover 2 includes an upper clamping cover 3 and a lower clamping cover 4. The lower clamping cover 4 is fixedly connected to the rear end of the plug body 1. The upper clamping cover 3 is above the lower clamping cover 4, and its front end is rotatably connected to the lower clamping cover 4. The IDC terminal block 8 is inside the lower clamping cover 4, and one end of it is snap-fitted to the lower clamping cover 4. A wire block 12 is also installed above the IDC terminal block 8. The lower pressure cover 4 includes a first mounting part 401 and a second mounting part 402. The first mounting part 401 is used to snap-fit ​​with the plug body 1. The first mounting part 401 has a hollow first receiving cavity 401-1. The plug body 1 is inserted into the first receiving cavity 401-1. The inner side wall of the first receiving cavity 401-1 has a raised second protrusion 401-2. The plug body 1 has a second socket 101 that engages with the second protrusion 401-2. The IDC terminal block 8 is installed in the second mounting part 402.

[0030] The upper pressure cover 4 has a first support base 5 and a second support base 6 extending upwards on its left and right sides, respectively. The first support base 5 and the second support base 6 have the same structure and are symmetrically arranged. The upper pressure cover 3 is rotatably connected to the first support base 5 and the second support base 6. The first support base 5 has a circular through hole 502, which is an opening structure that expands and extends towards the IDC terminal block 8. The upper pressure cover 3 has a rotating shaft 7 on its left and right inner walls, which rotates within the circular through hole 502. One end of the rotating shaft 7... Fixedly connected to the upper pressure cover 3, a limiting platform 701 protrudes outward along its axis on its other side. The limiting platform 701 is a circular ring structure and is coaxially arranged with the rotating shaft 7. The limiting platform 701 is located inside the circular through hole 502. The circular through hole 502 has a recessed limiting groove 502-1 corresponding to the position of the limiting platform 701. The front side of the IDC terminal block 8 abuts against the opening of the circular through hole 502, forming a closed movable space C between the circular through hole 502 and the circular through hole 502. The rotating shaft 7 rotates within the movable space C. In this application, the circular through hole 502 is above its opening, and the circular through hole 502 and its opening position are connected to form an elongated installation channel. The installation channel is inclined towards the IDC terminal block 8. In order to facilitate the orientation and installation of the rotating shaft 7 into the circular through hole 502, the inclined structure of the installation channel allows the channel to achieve the maximum length within the limited width range of the support base, ensuring that the rotating shaft 7 will not easily detach from the outside of the circular through hole 502.

[0031] A first hook 501 extends from the top of the first support base 5 toward the IDC terminal block 8. A second hook 801 is provided on the front side of the IDC terminal block 8 toward the first support base 5. The first hook 501 and the second hook 801 are interlocked. A second hook 801 with the same structure is provided on the right side of the IDC terminal block 8 and is interlocked with the second support base 6. The first hook 501 and the second hook 801 are installation structures with hooks for interlocking. In this application, the inner end face of the first hook 501 is on the left side of the limiting groove 502-1, and a step is formed between the inner end face of the first hook 501 and the first support base 5 for supporting the limiting platform 701. When the rotating shaft 7 is installed into the circular through hole 502, the limiting platform 701 on the rotating shaft 7 is in the limiting groove 502-1. At the same time, the side of the limiting platform 701 contacts the side of the first hook 501. The first hook 501 also forms a limiting installation structure for the rotating shaft 7. The first hook 501 and the limiting groove 502-1 form a limiting installation structure for the left and right sides of the rotating shaft 7.

[0032] The front end face of the IDC terminal block 8 is also provided with a first stop bar 802. There are two first stop bars 802, which are symmetrically arranged on the IDC terminal block 8. The two first stop bars 802 are between the two second hooks 801. The first stop bars 802 are above the limiting groove 502-1, and the end face of the first stop bar 802 is tangent to the outer end face of the limiting platform 701. The first stop bars 802 are arranged in the vertical direction, and the front and rear positions of the rotating shaft 7 can be limited by the first stop bars 802.

[0033] In this application, when assembling the crystal head, the PCB board 11 is first inserted into the lower cover 4, and then the first mounting part 401 of the lower cover 4 is snapped together with the plug body 1. The rotating shaft 7 of the upper cover 3 is first installed into the circular through hole 502 through the corresponding channels on the first support base 5 and the second support base 6. Then, the IDC terminal block 8 is placed above the PCB board 11, and the second hook 801 on the IDC terminal block 8 is engaged with the first hook 501, so that the upper cover 3 and the lower cover 4 can be rotated and installed.

[0034] The lower pressure cover 4 and the upper pressure cover 3 are provided with a tail sleeve 10 at their rear ends to lock the upper pressure cover 3 and the lower pressure cover 4. A tail clip 9 is installed inside the lower pressure cover 4. In this application, the plug body 1, IDC terminal block 8, wire clamp cover 2 and tail sleeve 10 are all made of plastic. The tail clip 9 includes a horizontally arranged positioning plate 901 and a wire holder 902 on the rear side of the positioning plate 901. The wire holder 902 has a concave lower arc groove 902-1. The rear side of the upper pressure cover 3 is provided with a concave upper arc groove 301. The outer sides of the upper arc groove 301 and the lower arc groove 902-1 are respectively provided with external threads. The upper arc groove 301 and the lower arc groove 902-1 are closed to form a circular external thread diameter, which is threadedly connected to the tail sleeve 10.

[0035] The front end of the positioning plate 901 extends toward the plug body 1 and has a third hook 903. The first mounting part 401 inside the lower cover 4 has a recessed first groove 401-3 that engages with and limits the third hook 903. The left and right ends of the front side of the wire holder 902 have first protrusions 902-3 protruding outwards respectively. The lower cover 4 has a first insertion hole 402-1 that corresponds to and engages with the first protrusion 902-3.

[0036] A raised second stop bar 902-4 is provided on the lower front side of the cable holder 902. The rear side of the lower pressure cover 4 is provided with a limiting hole 402-2 with an opening structure that cooperates with the position of the second stop bar 902-4. The third hook 903 on the front side of the positioning plate 901 and the second stop bar 902-4 behind the cable holder 902 realize the positioning and installation of the tail clip 9 in the lower pressure cover 4. While limiting the front and rear position of the tail clip 9 in the lower pressure cover 4, the second stop bar 902-4 can also play a guiding role, so that the tail clip 9 can be oriented and precisely installed in the lower pressure cover 4.

[0037] The rear side of the IDC terminal block 8 is provided with several plug blocks 803. The cable holder 902 is provided with slots that cooperate with the plug blocks 803 for insertion. The plug blocks 803 and slots allow the IDC terminal block 8 and the cable holder 902 to be positioned and installed. After the corresponding cable is installed with the IDC terminal block 8 and the cable block 12, the upper pressure cover 3 and the lower pressure cover 4 are fastened together. The tail sleeve 10 is screwed onto the external thread diameter to achieve cable positioning. That is, no special installation tools are required during installation. Simply insert the stripped wire along the corresponding wire hole and fasten the upper pressure cover 3 and the lower pressure cover 4 to connect the network cable connector.

[0038] Compared with the prior art, the one-way snap-fit ​​crystal head of this application has a compact structure. It uses the IDC terminal block, the first hook and the second hook to form an active space, so that the limiting platform on the rotating shaft is limited to rotate within the active space by the limiting groove. This effectively prevents the upper and lower pressure covers from separating during the assembly. This installation structure makes the connection between the upper and lower pressure covers more stable, and the snap-fit ​​installation connection between each component is fixed, resulting in high overall assembly efficiency of the crystal head.
