A kind of connecting structure for jumper crystal head and sheath

Abstract

This utility model provides a connection structure for jumper connectors and protective sleeves, belonging to the field of RJ45 technology. It includes an RJ45 connector body and a protective sleeve fitted onto the connector body, and further includes a connection assembly. The connection assembly includes a connection portion disposed at the end of the protective sleeve, and a connection spring is fixed to the outer side of the connection portion. In use, the connection spring causes the connection portion to engage with a groove in the RJ45 connector body. With this utility model, when the protective sleeve needs to be removed, the user pinches the surface of the air bladder cloth with their fingers, pressing the gas in the compression chamber through air passage two and air passage one into the expansion chamber. This increases the pressure in the expansion chamber, causing the expansion portion to straighten. The expansion portion then causes the connection spring to disengage from the groove in the RJ45 connector body, allowing the protective sleeve to be pulled out directly. This makes operation more convenient. Furthermore, when the RJ45 connector body is impacted, the protruding expansion cloth also acts as a buffer, further improving the protection of the RJ45 connector body.

Description

Technical Field

[0001] This utility model relates to the field of crystal head technology, and in particular to a connection structure for jumper crystal heads and sheaths. Background Technology

[0002] The RJ45 patch cord is the connecting component of a network patch cord. The metal substrate is mostly phosphor bronze plated with nickel and then gold, and the plastic shell is usually PC. It is used to connect the network cable to the network device interface to realize signal transmission. The sleeve is the accessory that covers the RJ45 connector. The material is PVC / PE, PA, etc., and it plays a role in protecting the RJ45 connector, reducing cable pulling, resisting interference, and preventing dust. Some can also relieve stress to prevent cable breakage. There is a groove at the bottom of the RJ45 connector. When the sleeve is inserted into the RJ45 connector, the protrusion on the inner wall of the sleeve can engage with the inner wall of the groove to connect the sleeve and the RJ45 connector.

[0003] When the sheath needs to be removed, the protrusion inside the sheath must first be pulled outward by hand to disengage it from the groove, and then the sheath must be pulled outward. This operation is cumbersome. Therefore, this application provides a connection structure for the jumper head and the sheath to meet the requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a connection structure for jumper heads and sheaths to solve the problem of cumbersome sheath disassembly.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A connection structure for a patch cord RJ45 connector and its protective sleeve includes a connector body and a protective sleeve fitted onto the connector body, and further includes:

[0007] The connecting assembly includes a connecting part disposed at the end of the protective sleeve. A connecting spring is fixed to the outer side of the connecting part. In use, the connecting spring drives the connecting part to engage in the groove of the crystal head body. An airbag cloth is fixed to the side of the protective sleeve. A pressing cavity is formed between the airbag cloth and the protective sleeve. An expansion cavity is disposed inside the connecting part. An air passage one is opened on the inner wall of the expansion cavity. An air passage two is opened on the inner wall of the pressing cavity. Air passage one and air passage two are connected.

[0008] Preferably, the surface of the airbag fabric is provided with anti-slip stripes.

[0009] Preferably, the end of the protective sleeve is connected to a round sleeve, and the top of the protective sleeve is fixed with a square strip, which is attached to the surface of the snap-fit ​​strip of the crystal head body.

[0010] Preferably, the inner wall of the circular sleeve is provided with anti-slip stripes.

[0011] Preferably, a guide surface is provided at the opening edge of the protective sleeve.

[0012] Preferably, the end of the connecting portion is provided with a second guide surface.

[0013] Preferably, the edges of the protective sleeve are chamfered.

[0014] Preferably, the protective cover is a plastic cover.

[0015] Preferably, the cross-section of the airway is square.

[0016] Preferably, the cross-section of the second airway is circular.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] In the above solution, through the connecting component, when the protective cover needs to be removed, pinch the surface of the airbag cloth with your fingers, and press the gas in the pressing chamber into the expansion chamber through air passage two and air passage one. After the pressure in the expansion chamber increases, the expansion part will straighten, and the expansion part will drive the connecting spring to disengage from the groove of the crystal head body. Then the protective cover can be pulled out directly, making the operation more convenient. Secondly, when the crystal head body is hit, the protruding expansion cloth can also play a buffering role, further improving the protection capability of the crystal head body.

[0031] like Figures 1-5 As shown, an embodiment of this utility model provides a connection structure for a jumper connector and a protective sleeve, including a connector body 1 and a protective sleeve 2 fitted onto the connector body 1, and further including:

[0032] Connecting assembly 5 includes a connecting part 6 disposed at the end of the protective sleeve 2. A connecting spring 7 is fixed to the outer side of the connecting part 6. In use, the connecting spring 7 drives the connecting part 6 to engage with the groove in the crystal head body 1. An airbag cloth 8 is fixed to the side of the protective sleeve 2, forming a pressing cavity 10 between the airbag cloth 8 and the protective sleeve 2. An expansion cavity 9 is disposed inside the connecting part 6. An air passage 11 is formed on the inner wall of the expansion cavity 9, and an air passage 2 12 is formed on the inner wall of the pressing cavity 10. The air passage 11 and the air passage 2 12 are connected. The connecting spring 7 and the connecting part 6 are connected to the protective sleeve 2. The protective sleeve 2 is securely connected to the crystal head body 1 by engaging with the groove in the crystal head body 1, preventing the protective sleeve 2 from accidentally falling off. When the airbag cloth 8 is pressed, the gas in the pressing chamber 10 enters the expansion chamber 9 through the second air passage 12 and the first air passage 11, increasing the air pressure in the expansion chamber 9. This causes the structure in the connecting part 6 to expand, driving the connecting spring 7 to disengage from the groove, making it easier to remove the protective sleeve 2. In addition, the structure of the airbag cloth 8 and the expansion chamber 9 can act as a buffer when the crystal head body 1 is impacted, reducing damage to the crystal head from external forces.

[0033] like Figures 1-2 As shown in this embodiment, the surface of the airbag fabric 8 is provided with anti-slip stripes. The anti-slip stripes increase the friction of the airbag fabric 8 surface, making it less likely for the operator's fingers to slip when pressing the airbag fabric 8, improving the stability and convenience of the operation, and ensuring that the process of removing the protective cover 2 is carried out smoothly.

[0034] like Figures 1-3 As shown, in this embodiment, the end of the protective sleeve 2 is connected to a circular sleeve 3, and the top of the protective sleeve 2 is fixed with a square strip 4. The square strip 4 is attached to the surface of the snap strip of the crystal head body 1. The circular sleeve 3 is sleeved on the outside of the network cable to further fix the connection between the network cable and the crystal head body 1, reduce the impact of network cable shaking on the crystal head, and improve the reliability of the overall structure.

[0035] like Figure 3 As shown, in this embodiment, the inner wall of the circular sleeve 3 is provided with anti-slip stripes. The anti-slip stripes on the inner wall of the circular sleeve 3 increase the friction with the surface of the network cable, making the circular sleeve 3 more firmly attached to the network cable, effectively preventing the network cable from falling out of the protective sleeve 2, and enhancing the protection of the connection between the crystal head and the network cable.

[0036] like Figure 2 As shown in this embodiment, a guide surface 13 is provided at the opening edge of the protective sleeve 2. The guide surface 13 is inclined. When installing the protective sleeve 2, it can guide the protective sleeve 2 to be smoothly put onto the crystal head body 1, reduce the resistance during insertion, avoid damage to the protective sleeve 2 or the crystal head body 1 due to hard insertion, and improve the convenience of installation and the durability of the structure.

[0037] like Figure 4As shown, in this embodiment, the end of the connector 6 is provided with a guide surface 14. The inclined design of the guide surface 14 allows the connector 6 to be inserted more smoothly into the groove of the crystal head body 1 when it is installed with the protective sleeve 2, which helps the connector spring 7 to be accurately engaged, further reducing the installation difficulty and ensuring that the connector assembly 5 works normally.

[0038] like Figure 2 As shown in this embodiment, the edge of the protective sleeve 2 is chamfered. The chamfer design eliminates the sharp edges of the protective sleeve 2. When installing or removing the protective sleeve 2 or the crystal head body 1 comes into contact with other components, it can reduce friction and collision damage, improve safety, and avoid scratching operators or damaging other equipment.

[0039] like Figure 2 As shown in this embodiment, the protective sleeve 2 is a plastic sleeve. The plastic protective sleeve 2 has the characteristics of being lightweight, low cost, good insulation, and wear-resistant. It can effectively protect the crystal head body 1, and is easy to process and mold and mass-produce. At the same time, the insulation can prevent external electromagnetic interference from affecting the signal transmission of the crystal head.

[0040] like Figure 4 and Figure 5 As shown, in this embodiment, the cross-section of the air passage 11 is square. The square cross-section of the air passage 11 can provide a larger gas flow area, which helps to quickly transmit the gas in the pressing chamber 10 to the expansion chamber 9, so that the expansion chamber 9 can be pressurized quickly, ensuring that the connecting spring 7 can be disengaged from the groove in time, and improving the efficiency of disassembling the protective sleeve 2.

[0041] like Figure 4 and Figure 5 As shown, in this embodiment, the cross-section of the second air passage 12 is circular. The inner wall of the second air passage 12 with a circular cross-section is smooth, and the resistance to gas flow is small, which can reduce the loss of gas during transmission. This allows the gas in the pressing chamber 10 to pass through the second air passage 12 more smoothly into the first air passage 11, ensuring that the pressurization process of the expansion chamber 9 is stable and efficient.

[0042] Working principle: Align the protective sleeve 2 with the crystal head body 1, rotate the connecting spring 7 outward, and use the guide surface 13 on the opening edge of the protective sleeve 2 and the guide surface 14 at the end of the connecting part 6 to smoothly fit the protective sleeve 2 onto the crystal head body 1. At this time, the connecting spring 7 of the connecting assembly 5 drives the connecting part 6 to engage in the groove of the crystal head body 1. Simultaneously, the square strip 4 on the top of the protective sleeve 2 fits against the snap strip surface of the crystal head body 1, and the anti-slip stripes on the inner wall of the round sleeve 3 are in close contact with the network cable, completing the installation of the protective sleeve 2; when it is necessary to remove the protective sleeve 2... When using the protective sleeve 2, pinch the surface of the airbag cloth 8 with your fingers and use its anti-slip stripes to increase friction. The gas in the pressing chamber 10 is forced into the expansion chamber 9 through the second air passage 12 and the first air passage 11, which increases the pressure in the expansion chamber 9. This causes the structure in the connecting part 6 to expand, which in turn causes the connecting spring 7 to disengage from the groove of the crystal head body 1. At this time, the protective sleeve 2 can be pulled outward. During the disassembly process, the chamfered edge of the protective sleeve 2 can reduce friction with other parts, and the protruding structure can play a buffering role when the crystal head body 1 is hit, thus protecting the crystal head body 1.

To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
