Description

Technical Field

[0001] The invention belongs to the technical field of connectors, in particular to an eight-core industrial Gigabit Ethernet fast connector. Background Art

[0002] The eight-core industrial Gigabit Ethernet connector is an essential component of network data in the industrial field and the main bridge for terminal communication. Although there are many eight-core Gigabit Ethernet quick connectors of different shapes and types on the market, the various connectors can reflect fast wiring, but they are far from satisfactory in terms of performance, operation method, reliability, structure, and applicable occasions.

[0003] The main reason is that there are 5 serious structural defects:

[0004] 1. Open the shell at the bottom, the terminal hole position is just opposite to what you see visually, which can easily lead to errors, reduced efficiency and failure of normal communication. The plastic cover is smooth and difficult to hold, and the hands that have crimped the wires cannot be removed in parallel. You can only use tools to pry open the crimping cover. Prying open the one-way starting point will cause the contact hardware inside to become skewed and deformed, and the fork will become larger and unstable and cannot be reused.

[0005] 2. The butterfly-shaped opening structure, the wiring fork is inserted from both sides, and the supporting colloid is very weak. If the connection is wrong or reversed, it is necessary to repeatedly reconnect the wiring. The plastic protrusions on both sides of the main shell are only 0.35mm. After the support is fixed, it is pressed toward the center by the outer cover. After three round trips, the plastic protrusions will be worn to 0.25mm. After repeated times, it is easy to fall off and cannot be positioned. It is unreliable and cannot be used.

[0006] 3. The open-type crimping cover has no fool-proof function and is easy to be inserted upside down, which will distort the wiring blade. If the blade is crooked or misplaced, the wire cannot be broken or clamped and cannot be used anymore. The crimping cover is smooth as a whole and difficult to install or remove. It needs to be pried open and removed with tools, and the blade is deformed and cannot be used anymore.

[0007] 4. Some of the PCB boards that are in contact with the network port are directly extended to the front end for contact riveting or welding. The span is too long, and the PCB boards in different environments will experience unstable thermal expansion and contraction, insufficient tensile strength, different contact resistances, increased return loss, crosstalk, and other effects, which cannot achieve stable gigabit transmission.

[0008] 5. The flip cover will fall freely when opened, which is inconvenient to operate, and the fingers are not enough to take and install. The outlet is not suitable for regularization, the outer skin with a diameter of less than 6mm will be loose and cannot be pressed tightly, the shielding net cannot be in good contact with the outer shell, and the shielding performance is poor; the outer skin with a diameter of 7-8.2mm cannot be put into the outlet for normal installation, the compatibility is poor, and the applicability is limited.

[0009] Therefore, we propose an eight-core industrial Gigabit Ethernet fast connector. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The following will be combined Figure 1-Figure 7 An eight-core industrial Gigabit Ethernet fast connector according to an embodiment of the present invention is described in detail.

[0035] Reference Figure 1-7 ,

[0036] Example:

[0037] Reference Figure 1-Figure 3, an eight-core industrial Gigabit Ethernet fast connector, including a high-density zinc alloy body 1; specifically, the high-density zinc alloy body 1 is made of zinc alloy, which has a moderate melting point, good fluidity, easy fusion welding, high strength, good toughness, corrosion resistance in the atmosphere, good shielding, and the residual waste is easy to recycle for environmental protection; the high-density zinc alloy body 1 includes a lower shell 8 and an upper shell flip cover 9, the outer side of the lower shell 8 is provided with a track-type active groove 6, the upper end of the high-density zinc alloy body 1 is embedded with a plastic core 7, and the plastic core 7 also includes a low-resistance and high-conductivity copper plated with 50U gold A / B connecting piece , a PCB board with enhanced anti-crosstalk circuit design, a PC material insulating base plate and a wire buckle with a wire identification. Specifically, the plastic core 7 is made of nylon material that can withstand high temperatures of 230 degrees, has good rigidity, is not easy to deform, has strong elasticity, is corrosion-resistant, and has a small shrinkage ratio. It is used to fix, support, and isolate the inside of the joint, and a piece of high-hardness PC material board with 3000V voltage isolation insulation is embedded in the bottom of the plastic core 7. As an insulating material, the PC material board has high insulation performance and high temperature resistance, can effectively isolate different circuit parts, prevent current from passing through, and ensure the normal operation of the circuit.

[0038] Reference Figure 1-Figure 3 The upper outer surface of the high-density zinc alloy body 1 is provided with a low-resistance gold-plated contact piece 2, and the low-resistance gold-plated contact piece 2 extends from one end of the upper surface of the high-density zinc alloy body 1 to the upper right side of the high-density zinc alloy body 1. The upper left side of the high-density zinc alloy body 1 is provided with an anti-stuck release buckle 3, an anti-collision boss 4 and a secondary buckle 5. Specifically, the anti-stuck release buckle 3 is bent 90 degrees to ensure that the spring piece can buckle the main body normally regardless of the high point or the low point, and can prevent jamming and preventing failure to buckle. It is more reliable and more practical than a single-piece 0.3mm stainless steel spring piece as the end face as a card point; the secondary buckle 5 is used to support the main body in the middle to prevent the swing amplitude from being too large, resulting in poor contact at the front contact point and causing disconnection and packet loss, and strengthening the second buckle more firmly; the lower surface of the lower shell 8 and the upper shell flip cover 9 is provided with a tail locking buckle 12, and the outer surface of the tail locking buckle 12 is provided with a locking buckle 10 and a locking buckle 2 11 with a screwdriver assist opening.

A convex annular track 15 is provided on the outer surface of the tail end of the lower shell body 8 close to the groove 13; specifically, the convex annular track 15 is composed of a linear guide rail and an arc guide rail to form a closed high-precision annular track system. The material has been hardened and has high wear resistance and high precision. The cooperation of the inner circular guide groove 14 and the convex annular track 15 can allow the annular guide to rotate unimpeded. Compared with the screw thread, it is easy to install but will not reverse or fall off.

[0040] Reference Figure 1-Figure 4 , an anti-stuck and risk-avoiding release buckle 16 is installed on the outer side of one end of the lower shell 8 near the tail locking buckle 12; specifically, the anti-stuck and risk-avoiding release buckle 16 is used to insert a 2.5mm diameter flat-head screwdriver from the bottom back of the body when the front finger cannot press the release buckle or is blocked and cannot be operated at all, so that the release buckle can be completely and intactly removed and easily pulled out; a wire pressing cover 17 is arranged inside the lower shell 8 and the upper shell flip cover 9, a rib point 19 is arranged at one end of the upper shell flip cover 9 near the tail locking buckle 12, and a positioning guide column 18 is arranged at one end of the lower shell 8 near the tail locking buckle 12, and the ... The outer surface of the column 18 abuts against the inner surface of the rib point 19; specifically, the overlap of the positioning guide column 18 and the rib point 19 can prevent the cover from being misaligned when it is pressed, ensuring that the lower shell 8 and the upper shell flip cover 9 are covered and the cables are locked. The cooperation of the above structure can be compatible with a variety of cable sizes, suitable for various network ports and with swing protection buckle support to prevent falling off, improve the efficiency of installation and wiring, and have a long plug-in life. The quick wiring method can be completed simply without a crimping tool. The crimping cover 17 is easy to remove and install, and the wiring is intuitive when viewed from the front, which prevents the wrong line sequence from being connected, and can ensure the transmission of a gigabit low-latency network high-speed connector.

[0041] Reference Figure 4-Figure 7 , the inner side wall of the upper shell flip cover 9 away from the end near the tail locking buckle 12 is provided with a spike 20 and a cable shielding mesh layer locking contact platform 21, and the middle part of the inner side wall of the upper shell flip cover 9 is fixedly connected with a reinforcing rib 22 for compressing the wire pressing cover 17, and the lower surface of the wire pressing cover 17 is installed with a knife edge sheet hole 31 and a step 32; specifically, the spike 20 can lock the cable to prevent the outer skin from falling off, and the reinforcing rib 22 can support the wire pressing cover 17 to prevent the wire in the wire pressing cover 17 from curling up, and keep the wire core in close contact with the knife edge sheet; an upper wire hole 23 and a lower wire hole 24 are provided on one side of the wire pressing cover 17 near the tail locking buckle 12, and an inlet 26 is provided inside the end of the tail locking buckle 12 near the lower shell 8; specifically, the number of wires used by the upper wire hole 23 and the lower wire hole 24 is four, and the inlet 26 is suitable for wires with an outer diameter of 8.4mm.

[0042] Reference Figure 4-Figure 7, the interior of the plastic core 7 is provided with an anti-oxidation short blade breaking wire piece 27 and an anti-oxidation long blade breaking wire piece 28, and one end of the low-resistance gold-plated contact piece 2 is connected to the anti-oxidation short blade breaking wire piece 27 and the anti-oxidation long blade breaking wire piece 28; specifically, the anti-oxidation short blade breaking wire piece 27 and the anti-oxidation long blade breaking wire piece 28 are placed obliquely to evenly divide the equal length lines and the span sizes are different, which prevents the blade pieces from being too close to prevent excessive crosstalk. The plastic core 7 is connected to the inner side wall of the high-density zinc alloy body 1 through an anti-falling hook 29 and a convex stop device 30; specifically, the anti-falling hook 29 is a fixing function of the hook when installing the line and repeatedly disassembling and pulling out the cable, and the device will not be lifted together with the cable, and the convex stop device 30 is used to prevent the upper shell cover from falling off during opening and closing.
