[0004] Therefore, an electronic connecting wire with flame retardant and heat resistant effects is proposed. Utility Model Content
[0005] The utility model aims to solve the problem that the sheath of the electronic connecting wire is easily damaged by heat, which causes the wire core of the electronic connecting wire to be exposed and damaged, and proposes an electronic connecting wire with flame retardant and heat resistant effects.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an electronic connecting wire with flame retardant and heat resistant effects, comprising a sheath, a wire core is passed through the sheath, an insulating sheath is provided on the outer wall of the sheath, a flame retardant sheath is provided on the outer wall of the sheath, the insulating sheath and the flame retardant sheath are both made of polyvinyl chloride, and an expanding foaming agent is filled between the insulating sheath and the flame retardant sheath.
[0007] The effect achieved by the above components is: when a fire occurs or high temperature appears around the electronic connecting wire, the external heat will be transferred to the expansion foaming agent through the flame retardant sleeve. When the temperature reaches a certain level, the expansion foaming agent will expand and form a porous structure inside. At this time, the porous structure inside the expansion foaming agent can prevent the external heat from being transferred to the insulating sleeve, thereby improving the heat resistance of the line, thereby preventing the sheath from being damaged by heat, and thus extending the service life of the electronic connecting wire.
[0008] Preferably, the outer wall of the flame retardant sleeve is provided with a wear-resistant sleeve, and the wear-resistant sleeve is a polyethylene sleeve.
[0009] The effects achieved by the above components are: since the polyethylene material has good wear resistance and flexibility, the wear-resistant sleeve made of polyethylene material ensures that the electronic connecting wire can be bent normally while also protecting the flame-retardant sleeve and the like.
[0010] Preferably, a plurality of protrusions are glued to the outer wall of the insulating sleeve, and the protrusions are snap-fitted and connected to the flame-retardant sleeve.
[0011] The effects achieved by the above components are as follows: the protrusions can increase the friction force of the outer wall of the insulating sleeve and limit the position of the redundant flame-retardant sleeve.
[0012] Preferably, a filling strip is glued to the outer wall of the flame retardant sleeve, and the filling strip is located inside the wear-resistant sleeve.
[0013] The effect achieved by the above components is that the filling strip can press the flame retardant sleeve tightly against the surface of the insulating sleeve, so that the heat generated by the wire core during operation can be normally transferred to the outside.
[0014] Preferably, the wear-resistant sleeve is embedded with a puncture-resistant net, and the puncture-resistant net is a nylon fiber woven net.
[0015] The effect achieved by the above components is: due to the high strength of nylon fibers, the puncture-resistant net woven from nylon fibers can effectively prevent sharp objects from piercing the wear-resistant sleeve, thereby improving the protective effect of the wear-resistant sleeve.
[0016] Preferably, a reinforcing core is provided inside the filling strip, and the reinforcing core is an aramid fiber core.
[0017] The effect achieved by the above components is that when laying electronic connecting wires, the reinforcing core made of aramid fiber material can improve the tensile strength of the electronic connecting wires, thereby facilitating the long-distance laying of the electronic connecting wires.
[0018] Compared with the prior art, the advantages and positive effects of the utility model are:
[0019] In the utility model, when a fire occurs or high temperature appears around the electronic connecting wire, the external heat will be transferred to the expansion foaming agent through the flame retardant sleeve. When the temperature reaches a certain level, the expansion foaming agent will expand and form a porous structure inside. At this time, the porous structure inside the expansion foaming agent can prevent the external heat from being transferred to the insulating sleeve, thereby improving the heat resistance of the line, thereby preventing the sheath from being damaged by heat, and thus extending the service life of the electronic connecting wire.

[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0026] like Figure 1-Figure 3 As shown, the utility model provides an electronic connecting line with flame retardant and heat resistant effects, including a sheath 1, a wire core 2 is inserted into the sheath 1, an insulating sheath 3 is provided on the outer wall of the sheath 1, a flame retardant sheath 4 is provided on the outer wall of the sheath 1, both the insulating sheath 3 and the flame retardant sheath 4 are made of polyvinyl chloride, and an expanding foaming agent 5 is filled between the insulating sheath 3 and the flame retardant sheath 4. When a fire occurs or high temperature occurs around the electronic connecting line, the external heat will be transferred to the expanding foaming agent 5 through the flame retardant sheath 4. The expanding foaming agent 5 will expand and form a porous structure inside after the temperature reaches a certain level. At this time, the porous structure inside the expanding foaming agent 5 can prevent the external heat from being transferred to the insulating sheath 3, thereby preventing the sheath 1 from being damaged by heat, thereby extending the service life of the electronic connecting line, and the outer wall of the flame retardant sheath 4 is provided with a wear-resistant sheath 6, which is a polyethylene sheath. Since the polyethylene material has good wear resistance and flexibility, the wear-resistant sheath 6 made of polyethylene material ensures that the electronic connecting line can be bent normally while protecting the flame retardant sheath 4 and the like.
[0027] like Figure 3As shown, the outer wall of the insulating sleeve 3 is glued with a plurality of protrusions 8, and the protrusions 8 are snap-connected with the flame-retardant sleeve 4. The protrusions 8 can increase the friction of the outer wall of the insulating sleeve 3 and limit the position of the redundant flame-retardant sleeve 4. The outer wall of the flame-retardant sleeve 4 is glued with a filling strip 7, and the filling strip 7 is located in the wear-resistant sleeve 6. The filling strip 7 can press the flame-retardant sleeve 4 against the surface of the insulating sleeve 3 so that the heat generated by the wire core 2 during operation can be normally transferred to the outside. The wear-resistant sleeve 6 is embedded with an anti-puncture net 9, and the anti-puncture net 9 is a nylon fiber woven net. Due to the high strength of nylon fiber, the anti-puncture net 9 woven from nylon fiber can effectively prevent sharp objects from piercing the wear-resistant sleeve 6, thereby improving the protective effect of the wear-resistant sleeve 6. A reinforcing core 10 is pierced through the filling strip 7, and the reinforcing core 10 is an aramid fiber core. When laying electronic connecting wires, the reinforcing core 10 made of aramid fiber can improve the tensile strength of the electronic connecting wires, thereby facilitating the long-distance laying of electronic connecting wires.
[0028] The overall working principle is that during the normal use of electronic connecting wires by semiconductor equipment, since the polyethylene material has good wear resistance and flexibility, the wear-resistant sleeve 6 made of polyethylene material ensures that the electronic connecting wires can be bent normally while protecting the flame-retardant sleeve 4, etc. The protrusion 8 can increase the friction of the outer wall of the insulating sleeve 3 and limit the position of the redundant flame-retardant sleeve 4. The filling strip 7 can press the flame-retardant sleeve 4 against the surface of the insulating sleeve 3, so that the heat generated by the wire core 2 during operation can be normally transferred to the outside. Since the strength of nylon fiber is relatively high, the puncture-resistant net 9 woven from nylon fiber can effectively prevent sharp objects from piercing the wear-resistant sleeve 6, thereby improving the protective effect of the wear-resistant sleeve 6. When laying the electronic connecting wires, the reinforcing core 10 made of aramid fiber material The invention can improve the tensile strength of the electronic connecting wire, thereby facilitating the long-distance laying of the electronic connecting wire. When a fire occurs or high temperature appears around the electronic connecting wire, after the wear-resistant sleeve 6, the filling strip 7, the puncture-resistant net 9 and the reinforcing core 10 are burned, the external heat will be transferred to the expanding foaming agent 5 through the flame retardant sleeve 4. When the temperature reaches a certain level, the expanding foaming agent 5 will expand and a porous structure will be formed inside. The flame retardant sleeve 4 made of polyvinyl chloride is difficult to be burned through by the flame, so that the expanding foaming agent 5 can be evenly distributed on the outer wall of the insulating sleeve 3, and the flame retardant sleeve 4 will be out of contact with the protrusion 8. At this time, the porous structure inside the expanding foaming agent 5 can prevent the external heat from being transferred to the insulating sleeve 3, thereby preventing the sheath 1 from being damaged by heat, thereby extending the service life of the electronic connecting wire.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
