Description

Technical Field

[0001] The utility model relates to the technical field of crystal plugs, in particular to an easily pluggable crystal plug. Background Art

[0002] The crystal head is a standardized telecommunication network interface. It provides an interface for voice and data transmission. The crystal head is a plastic connector that can be inserted in a fixed direction and automatically prevents it from falling off. It is commonly known as the "crystal head". The professional term is the RJ-45 connector (RJ-45 is a network interface specification. There is also a similar RJ-11 interface, which is the "telephone interface" we usually use to connect telephone lines). The reason why it is called a "crystal head" is because of its crystal clear appearance. The crystal head is suitable for on-site termination between equipment rooms or horizontal subsystems, and the shell material is high-density polyethylene. The two ends of each twisted pair are connected to the network card and hub (or switch) by installing a crystal head.

[0003] A crystal head is proposed in the utility model with Chinese patent publication number CN201360072Y. The crystal head adopts a step surface at the intersection of the outer riveted part and the core wire groove part as a reference, and a core wire groove inlet is set within the range of plus or minus three millimeters of the plane extending inward from the step surface. The core wire groove inlet is connected to the outer riveted cavity through an inclined surface. Therefore, the utility model can effectively avoid the effect of the plastic of the crystal head entering the core wire groove of the crystal head during injection molding. However, after studying the prior art, it is found that: the existing network interface (female socket) used for connecting the network cable and inserting the network interface is too dense and too shallow. After insertion, the spring piece is buckled, which is not conducive to manual pulling of the spring piece for extraction; for future waterproofing, the crystal head molding volume should be short to match the JACK (female socket), but the crystal head in the prior art is relatively large. Therefore, a crystal head that is easy to plug and unplug is proposed here. Utility Model Content

[0004] Technical issues solved

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and provide an easily pluggable crystal plug.

[0006] Technical Solution

[0007] To achieve the above object, the present utility model provides the following technical solution: A crystal head that is easy to plug and unplug, including a rubber core seat body. The front end or the rear end of the rubber core seat body has a groove for inserting a network core wire. The rubber core seat body is provided with an indented notch on both sides of the groove. An easy-to-plug-and-unplug elastic sheet is connected to the upper end of the rubber core seat body. By setting this crystal head, this crystal head is relatively short, and the design of the easy-to-plug-and-unplug elastic sheet is also short. After insertion, the latching force is small, resulting in a relatively small pulling force. After insertion, it is slightly latched for connection. When it needs to be pulled out, just pull the wire directly. It is very easy to insert and also easy to pull out, making it more convenient to use. There are concave holes on the easy-to-plug-and-unplug elastic sheet. The outer side of the rubber core seat body is covered with a shell made of nickel-plated copper shell material. By using a copper shell plated with nickel for the shell, oxidation can be prevented. Because after nickel plating, nickel does not eat tin, resulting in problems such as poor soldering and poor welding. One end of the shell is set in a dovetail shape, which can limit the network cable, and the network cable can be installed stably without welding.

[0008] Preferably, a dovetail-shaped tail clip is provided at the rear end of the shell.

[0009] Preferably, a stepped front end is provided at the front end of the shell.

[0010] Preferably, the length of the easy-to-plug-and-unplug elastic sheet is 6 - 10 mm.

[0011] Preferably, the length of the rubber core seat body is 10 - 15 mm.

[0012] Preferably, a docking block is provided at the bottom of the rubber core seat body, and a docking slot is provided inside the shell. The docking block can be adaptively inserted into the inside of the docking slot.

[0013] Preferably, two docking bumps are provided on the top of the shell.

[0014] Preferably, the rubber core seat body is further provided with slots on both sides of the groove, and the stepped front end of the shell is provided with a card board adapted to the slots.

[0015] Beneficial effects:

[0016] Compared with the prior art, this easy-to-plug-and-unplug crystal head has the following beneficial effects:

[0017] First, by setting this crystal head in the present utility model, this crystal head is relatively short, and the design of the easy-to-plug-and-unplug elastic sheet is also short. After insertion, the latching force is small, resulting in a relatively small pulling force. After insertion, it is slightly latched for connection. When it needs to be pulled out, just pull the wire directly. It is very easy to insert and also easy to pull out, making it more convenient to use.

[0018] Second, the outer shell of the present utility model is made of copper shell plated with nickel, which can prevent oxidation. Also, due to the problem that nickel does not eat tin and is not easy to solder (the ground wire of the outer shell) after nickel plating, one end of the outer shell is set in a dovetail shape, which can limit the network cable, and the ground wire of the network cable can be grounded without welding (the installation is stable).

Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0026] Please refer to Figures 1 to 3As shown, the utility model provides a technical solution: an easy-to-plug crystal head, including a rubber core seat body 1, the front end or rear end of the rubber core seat body 1 has a groove 2 for inserting the network core line, the rubber core seat body 1 is provided with an indented notch 3 on both sides of the groove 2, and an easy-to-plug spring piece 4 is connected to the upper end of the rubber core seat body 1. The crystal head is relatively short and the easy-to-plug spring piece is also designed to be short. The buckling force after insertion is small, resulting in a relatively small pull-out force. After insertion, it is slightly engaged for connection. When it needs to be pulled out, the line can be directly pulled out. It is very easy to insert and easy to pull out, and it is more convenient to use. A recessed hole 401 is provided on the easy-to-plug spring piece 4, and the outer side of the rubber core seat body 1 is covered with a shell 5 made of nickel-plated copper shell material. The shell is nickel-plated with copper shell to prevent oxidation. Because nickel does not eat tin after nickel plating and is not easy to solder or weld, one end of the shell is set to a dovetail type, so that the network cable can be limited, and the network cable can be installed firmly without welding.

[0027] Please pay attention to Figure 1 and Figure 3 A dovetail tail clip 501 is disposed at the rear end of the housing 5 , and a stepped front end 502 is disposed at the front end of the housing 5 . The length of the easy-plug spring 4 is 6-10 mm, and the length of the rubber core seat body 1 is 10-15 mm.

[0028] Please pay attention to Figure 3 A docking card block 101 is provided at the bottom of the rubber core seat body 1, and a docking card slot 503 is provided inside the shell 5. The docking card block 101 can be adaptably plugged into the inside of the docking card slot 503. Two docking protrusions 504 are provided on the top of the shell 5.

The stepped front end 502 of the shell 5 is provided with a card plate 505 adapted to the card slot 102.

[0029] Working principle: This crystal head is used to connect the network cable and then insert it into the network interface. Some network interfaces (female sockets) are too dense and too shallow. After insertion, the spring clip is buckled, which is not conducive to manual pulling of the spring clip for removal. Therefore, this crystal head is set. This crystal head is relatively short, and the plug-in spring clip design is also short. After insertion, the buckling force is small, resulting in a relatively small pull-out force. After insertion, it is slightly snapped for connection. When you need to pull it out, just pull the wire directly. It is very easy to insert and pull out, and it is more convenient to use; for future waterproofing, the molding volume should be short to match the JACK (female socket), solve the position where the traditional ground wire is not easy to weld, and the outer shell is nickel-plated with copper shell to prevent oxidation. Because nickel does not eat tin after nickel plating, it is not easy to solder and weld. One end of the outer shell is set to a dovetail style, which can limit the network cable, and the network cable can be installed firmly without welding the ground wire.
