DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the wiring head and hot melt glue gun assembly provided in the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0021] The present disclosure will be described more fully below with reference to the accompanying drawings, but the embodiments shown may be embodied in different forms, and the present disclosure should not be construed as being limited to the embodiments set forth below. On the contrary, the purpose of providing these embodiments is to make the present disclosure thorough and complete, and will enable those skilled in the art to fully understand the scope of the present disclosure.

[0022] The accompanying drawings of the embodiments of the present disclosure are used to provide a further understanding of the embodiments of the present disclosure, and constitute a part of the specification, and are used together with the detailed embodiments to explain the present disclosure, and do not constitute a limitation of the present disclosure. By describing the detailed embodiments with reference to the accompanying drawings, the above and other features and advantages will become more apparent to those skilled in the art.

[0023] The present disclosure may be described with reference to plan views and / or cross-sectional views by means of ideal schematic views of the present disclosure. Therefore, the exemplary illustrations may be modified according to manufacturing techniques and / or tolerances.

[0024] In the absence of conflict, the various embodiments of the present disclosure and the various features therein may be combined with each other.

[0025] The terms used in the present disclosure are only used to describe specific embodiments and are not intended to limit the present disclosure. The term "and / or" as used in the present disclosure includes any and all combinations of one or more related enumerated items. The singular forms "one" and "the" as used in the present disclosure are also intended to include plural forms, unless the context clearly indicates otherwise. The terms "including", "made of..." as used in the present disclosure specify the presence of the features, wholes, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or groups thereof.

[0026] Unless otherwise defined, all terms (including technical and scientific terms) used in this disclosure have the same meaning as commonly understood by those of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and this disclosure, and will not be interpreted as having an idealized or overly formal meaning unless explicitly defined in this disclosure.

[0027] The present disclosure is not limited to the embodiments shown in the drawings, but includes modifications of the configurations formed based on the manufacturing process. Therefore, the regions illustrated in the drawings have schematic properties, and the shapes of the regions shown in the drawings illustrate the specific shapes of the regions of the elements, but are not intended to be limiting.

[0028] In many cases, it is necessary to lay various cables in the environment.

[0029] For example, in all-optical networking applications, if concealed pipes cannot be used for laying (such as in old buildings), the only option is to use the open-wire laying solution for optical fibers (cables), that is, to fix the optical fibers (cables) directly on the walls of the room.

[0030] Among them, in the fiber to the room (FTTR) environment, specially customized invisible optical fibers are used. For example, the invisible optical fibers can be pressed onto wiring carriers such as walls first, and then hot melt glue guns are used to apply hot melt glue to the invisible optical fibers on the wiring carriers. After the hot melt glue solidifies, the invisible optical fibers are directly sealed inside, which can not only fix the invisible optical fibers, but also ensure the flatness and beauty of the structural appearance.

[0031] The above hot melt glue gun is a device used to melt solid hot melt glue and then apply it to the desired position. It may include components such as a glue outlet pipe, a heater, and a propulsion structure; wherein, solid hot melt glue (such as glue sticks, glue blocks, etc.) is added to the hot melt glue gun, then melted by the heater, and then pushed in the glue outlet pipe by the propulsion structure (such as a handle that can push the molten hot melt glue forward after being moved), so that the molten hot melt glue can flow out from the glue outlet end of the glue outlet pipe and be applied to the desired position.

[0032] It can be seen that the above wiring method requires that the cable (such as invisible optical fiber) be temporarily fixed (such as the operator pressing it with his hands) on the wiring carrier (such as the wall) first, and then hot melt adhesive is applied on the cable. Therefore, its operation is cumbersome and prone to errors (such as the cable being offset during the application of glue, or the hot melt adhesive being applied to the operator's hands, etc.).

[0033] To this end, a metal wiring head can be installed outside the glue outlet end of the glue outlet tube to form a hot melt glue gun assembly. The wiring head has a glue outlet connected to the glue outlet end (so the wiring head is equivalent to an "extension" of the glue outlet tube), and the cable to be laid bypasses the wiring head from the glue outlet. Therefore, the cable can be laid on the wiring carrier by simply using the wiring head to "push" the cable onto the wiring carrier, and then the hot melt glue gun assembly can be moved while discharging glue. At the same time, hot melt glue can be coated on the outside of the cable on the wiring carrier, so that wiring and sealing can be completed simultaneously in one operation.

[0034] However, the glue dispensing heads in the related art are all made of metal. Due to the high hardness of metal materials, when the glue dispensing heads come into contact with wiring carriers such as walls, the wiring carriers are easily scratched, resulting in scratches thereon and damaging the appearance of the wiring carriers. At the same time, the thermal conductivity of metal materials is very good, and the high-temperature hot melt adhesive must flow through the glue dispensing heads, which causes the temperature of the glue dispensing heads to be very high. If someone (such as an operator) accidentally touches the glue dispensing heads, it is easy to cause burns.

[0035] First, refer to Figures 1 to 7 The embodiment of the present disclosure provides a wiring head 2 for FTTR, which is used to be connected to a hot melt glue gun 1.

[0036] Reference Figure 1 The wiring head 2 of the disclosed embodiment can be installed on the hot melt glue gun 1 to form a hot melt glue gun assembly, which is used to complete the wiring and sealing of the cable 91 (such as optical fiber, especially the invisible optical fiber in FTTR) through one operation, that is, to achieve the placement of the cable 91 through one operation.

[0037] Among them, refer to Figure 3 The hot melt glue gun 1 includes a glue outlet tube 11 (such as a copper tube), and the glue outlet tube 11 has a glue outlet end 111 for allowing the hot melt glue 93 to flow out.

[0038] It should be understood that the hot melt glue gun 1 may also include other components such as a heater, a propulsion structure (such as a handle 19 that can push the molten hot melt glue 93 forward after being moved), etc., which will not be described in detail here.

[0039] It should be understood that when the wiring head is not installed, the separate hot melt glue gun 1 can also be used to perform other gluing operations, which will not be described in detail here.

[0040] Reference Figures 1 to 7 The wiring head 2 of the disclosed embodiment includes a wiring portion 22 made of a heat insulating material. When the wiring head 2 is connected to the hot melt glue gun 1, the wiring portion 22 is at least sleeved outside the glue outlet end 111 of the glue outlet tube 11 of the hot melt glue gun 1. The wiring portion 22 includes a glue outlet 221 for communicating with the glue outlet end 111, and a pressing surface 222 adjacent to the glue outlet 221 for pressing the cable 91.

[0041] Reference Figure 2 The wiring head 2 of the disclosed embodiment is detachably connected to the hot melt glue gun 1, that is, the wiring head 2 can be installed on the hot melt glue gun 1 and can also be removed from the hot melt glue gun 1 without damage.

[0042] The wiring head 2 includes a wiring portion 22. Among all the structures of the wiring head 2, at least the wiring portion 22 is made of a heat insulating material.

[0043] It should be understood that it is also feasible if other components in the wiring head 2 (such as the subsequent connecting portion 21) are also made of heat insulating materials; for example, the wiring head 2 as a whole can be completely made of heat insulating materials.

[0044] In the embodiments of the present disclosure, the thermal insulation material refers to a material with good thermal insulation performance.

[0045] In some embodiments, the insulating material is plastic.

[0046] As one mode of an embodiment of the present disclosure, plastic may be used as the heat insulating material constituting the wiring portion 22 .

[0047] Compared with metal materials, plastic has a lower hardness, so the wiring portion 22 formed by plastic is not easily scratched when in contact with the wiring carrier 92 .

[0048] It should be understood that it is also feasible to use other thermal insulation materials such as ceramics.

[0049] Reference Figure 2 , Figure 3 In the hot melt glue gun assembly, the wiring portion 22 is at least "sheathed" at the glue outlet end 111 of the glue outlet tube 11; and referring to Figure 4 , Figure 5The wiring portion 22 has a glue outlet 221 connected to the glue outlet end 111 of the glue outlet tube 11 , so the hot melt adhesive 93 flowing out of the glue outlet end 111 can continue to enter the wiring portion 22 and finally flow out from the glue outlet 221 of the wiring portion 22 .

[0050] In the disclosed embodiment, the glue outlet 221 of the wiring portion 22 must be located outside the glue outlet end 111 of the glue outlet tube 11 , but the distance between the glue outlet 221 and the glue outlet end 111 can be “shorter”.

[0051] For example, see Figure 5 , Figure 7 The glue outlet end 111 may be only slightly "recessed" relative to the glue outlet 221, so that the wiring portion 22 is not an "extension" of the glue outlet tube 11, and the hot melt adhesive 93 flowing out of the glue outlet end 111 can flow out of the glue outlet 221 after passing a very short distance in the wiring portion 22.

[0052] Therefore, the hot melt glue gun assembly of the disclosed embodiment has fast glue discharge, and the sprayed hot melt glue 93 has high temperature, good fluidity, uniform distribution, and good coating effect; moreover, after the hot melt glue gun assembly is used up, there will be basically no "residual" hot melt glue 93 in the wiring head 2, that is, no sticking will occur, so when the hot melt glue gun assembly is used again subsequently, there is no need for long-term heating to melt the hot melt glue 93 in the wiring head 2, but the gluing can be started quickly, and the work efficiency is high.

[0053] Reference Figure 2 , Figure 5 , at least a portion of the surface of the wiring portion 22 adjacent to the glue outlet 221 (eg Figure 2 The surface at the lower side of the glue outlet 221 is the “pressing surface 222”, which is used to press the cable 91 onto a wiring carrier 92 such as a wall, so that the hot melt adhesive 93 subsequently flowing out of the glue outlet 221 can be accurately coated on the cable 91 on the wiring carrier 92.

[0054] In some embodiments, the pressing surface 222 is located on one side of the glue outlet 221 .

[0055] As one embodiment of the present disclosure, refer to Figure 2 The pressing surface 222 may be located only on one certain side of the glue outlet 221. Accordingly, the hot melt glue gun assembly needs to be operated in a specific direction (such as Figure 7 The cable 91 moves in the direction of the solid arrow in the middle, so that the cable 91 is first pressed by the pressing surface 222 and then passes through the glue outlet 221 to be coated with the hot melt glue 93.

[0056] It should be understood that it is also feasible if multiple sides of the glue outlet 221 are all pressing surfaces 222 .

[0057] In the present disclosure, refer to Figure 2 , Figure 5 For the convenience of operation, the pressing surface 222 may be in the form of a "slope" inclined relative to the axis of the rubber outlet pipe 11; for example, the slope is closer to one end of the rubber outlet pipe 11 ( Figure 7 The upper end of the inclination surface can be relatively "frontward (ie, close to the glue outlet 221)", while the inclined surface is farther away from the end of the glue outlet pipe 11 ( Figure 7 The lower end in the middle) can be relatively "backward (ie, away from the glue outlet 221)"; thus, referring to Figure 7 The hot melt glue gun assembly can also be "tilted" accordingly when in use, so that the pressing surface 222 in the form of an inclined surface can basically fit the wiring carrier 92 such as a wall.

[0058] Reference Figure 7 According to the embodiment of the present disclosure, when wiring, the unlaid cables 91 can be connected from one side of the rubber outlet pipe 11 ( Figure 7 The lower side of the wiring head 2 is introduced and the wiring head 2 is connected to the wiring head 2 through the front end ( Figure 7 The left end in the figure) is bypassed, and the front end of the wiring head 2 is pressed against the wiring carrier 92, so that the pressing surface 222 of the wiring portion 22 is basically in contact with the wiring carrier 92, and the cable 91 is "sandwiched" between the pressing surface 222 and the wiring carrier 92; then, it can be moved (along the Figure 7 hot melt glue gun assembly, push (along the Figure 7 The hot melt adhesive 93 is squeezed out and applied through the adhesive outlet tube 11, the adhesive outlet end 111, and the adhesive outlet 221 in sequence (in the direction of the dotted arrow in the figure), so that the hot melt adhesive 93 can be directly applied thereon while the cable 91 is pressed onto the wiring carrier 92.

[0059] In the disclosed embodiment, the wiring portion 22 of the wiring head 2 that contacts the wiring carrier 92 (such as a wall) is made of a heat-insulating material. Since the heat-insulating material has better heat-insulating properties than metal materials, it is not easy to cause burns to people during the wiring process.

[0060] In some embodiments, the wiring head 2 further includes: a connecting portion 21 , the connecting portion 21 is used for detachably connecting to the hot melt glue gun 1 , and the wiring portion 22 is connected to the connecting portion 21 .

[0061] As one mode of an embodiment of the present disclosure, the wiring head 2 may have a connecting portion 21 that is detachably connected to the hot melt glue gun 1, and the wiring portion 22 is connected to the connecting portion 21, so that when the connecting portion 21 is connected to the hot melt glue gun 1, it is equivalent to connecting the wiring portion 22 (wiring head 2) to the hot melt glue gun 1.

[0062] It should be understood that it is also feasible if there is no connecting portion but the wiring portion 22 is directly connected to the hot melt glue gun 1 .

[0063] There are various specific connection methods between the connection part 21 and the hot melt glue gun 1 .

[0064] For example, see Figure 3 , the outlet hose 11 is provided with an external thread 119 at a portion thereof, and the connecting portion 21 is provided with an internal thread matching the external thread 119, so as to refer to Figure 2 The connection portion 21 can be “sleeved” on the rubber outlet hose 11 by means of a threaded connection.

[0065] It should be understood that the connecting portion 21 can also be connected to other positions of the hot melt glue gun 1 through other means such as snap connection, which will not be described in detail here.

[0066] In some embodiments, when the wiring head 2 is connected to the hot melt glue gun 1 , the glue outlet tube 11 is sleeved inside the wiring head 2 .

[0067] Reference Figure 2 As one mode of the embodiment of the present disclosure, in the hot melt glue gun assembly, the glue outlet tube 11 can be "entirely" sheathed in the wiring head 2, so that the side of the glue outlet tube 11 is wrapped by the wiring head 2 and will not be "exposed", which can better avoid burns; at the same time, since the heat insulation material has good heat insulation properties, the wiring head 2 wrapping the glue outlet tube 11 can also achieve better heat preservation effect, increase the temperature of the hot melt adhesive 93 in the glue outlet tube 11, make it melt more fully, and better prevent sticking.

[0068] There are various specific ways to sleeve the wiring head 2 onto the hose 11 .

[0069] For example, see Figure 2 The connecting portion 21 of the wiring head 2 is sleeved on the "root (the portion away from the glue outlet end 111)" of the glue outlet tube 11, while the wiring portion 22 is sleeved on the "front (the portion close to the glue outlet end 111)" of the glue outlet tube 11.

[0070] In some embodiments, when the wiring head 2 is connected to the hot melt glue gun 1 , the wiring portion 22 can rotate around the axis of the glue tube 11 .

[0071] Reference Figure 2 As one embodiment of the present disclosure, in the hot melt glue gun assembly, the wiring portion 22 can be designed to be able to "rotate" relative to the axis of the glue outlet tube 11, and the rotation of the wiring portion 22 is equivalent to making the pressing surface 222 "facing" different directions relative to the hot melt glue gun 1; therefore, when wiring on wiring carriers 92 of various shapes, angles, and positions (such as the corners of the wall, etc.), the wiring portion 22 can be rotated to different angles according to the situation of the wiring carrier 92 to ensure that the pressing surface 222 can always press the cable 91 on the wiring carrier 92 from the appropriate direction, thereby improving the operability of the hot melt glue gun assembly.

[0072] In some embodiments, the connection portion 21 is used to be sleeved outside the rubber outlet hose 11 ; the wiring portion 22 is rotatably connected to the connection portion 21 .

[0073] Reference Figure 2 , Figure 5 As one embodiment of the present disclosure, in the hot melt glue gun assembly, the connecting portion 21 can be sleeved outside the glue outlet pipe 11, such as the connecting portion 21 can be adopted as reference Figure 3 The threaded connection method is sleeved on the "root" of the outlet hose 11, and the wiring part 22 is rotatably connected relative to the connecting part 21 and sleeved on the "front" of the outlet hose 11. Therefore, when the wiring part 22 rotates relative to the connecting part 21, it is equivalent to rotating around the outlet hose 11.

[0074] The rotation between the wiring portion 22 and the connecting portion 21 may be in the form of "damped rotation", that is, the wiring portion 22 needs to overcome a certain "resistance" when rotating relative to the connecting portion 21, thereby preventing the wiring portion 22 from being too flexible and causing unnecessary rotation.

[0075] For example, see Figure 2 , Figure 5 The wiring head 2 also includes a damping shaft 231 and a fixing member 232, wherein the damping shaft 231 is rotationally connected to the connecting portion 21 (damped rotation), and the wiring portion 22 is connected to the damping shaft 231 through the fixing member 232, so that when the damping shaft 231 rotates relative to the connecting portion 21, the wiring portion 22 rotates relative to the connecting portion 21 (damped rotation).

[0076] It should be understood that the specific location of the wiring portion 22 , the specific location of the connecting portion 21 , the specific rotational connection method between the wiring portion 22 and the connecting portion 21 , etc. are not limited to the above examples.

[0077] For example, the wiring portion 22 may be directly fixedly connected to the connecting portion 21 , and the connecting portion 21 may rotate relative to the rubber outlet hose 11 , thereby driving the wiring portion 22 to rotate around the rubber outlet hose 11 ; or, the wiring portion 22 may be directly rotatably connected to the rubber outlet hose 11 .

[0078] In some embodiments, the pressing surface 222 is located on one side of the glue outlet 221 . The wiring portion 22 further includes a positioning hole 223 for the cable 91 to pass through, and the positioning hole 223 is located on the side of the pressing surface 222 away from the glue outlet 221 .

[0079] Reference Figure 5 The wiring portion 22 may also be provided with a positioning hole 223, and the positioning hole 223 and the glue outlet 221 are respectively located on two opposite sides of the pressing surface 222, that is, the positioning hole 223 is provided on the "introduction side (such as Figure 5The cable 91 before being laid can first pass through the positioning hole 223 and be limited to a certain position, then pass through the pressing surface 222 from this position, and then pass through the glue outlet 221 to be coated with hot melt glue 93 to ensure that the cable 91 will not "derail" by moving without passing through the pressing surface 222.

[0080] The specific positions, quantities, and other forms of the positioning holes 223 are various.

[0081] For example, refer to Figure 5 , Figure 6 There may be two positioning holes 223, one of which is located on a protruding positioning hanger 2239 that is relatively far away from the glue outlet 221, and the other positioning hole 223 is located on the wiring portion 22 very close to the glue outlet 221, so as to perform rough positioning and fine positioning of the cable 91 respectively.

[0082] In some embodiments, the pressing surface 222 is located on one side of the glue outlet 221 ; the wiring portion 22 also includes: a positioning groove 224 for the cable 91 to be inserted into, the positioning groove 224 is located on the pressing surface 222 , and extends in a direction from the glue outlet 221 to the pressing surface 222 .

[0083] Reference Figure 5 As one embodiment of the present disclosure, a positioning groove 224 may be provided on the pressing surface 222, and the positioning groove 224 extends in a direction from the glue outlet 221 to the pressing surface 222 ( Figure 5 The positioning groove 224 extends in the up-down direction in the middle of the pressing surface 222, so that at least a portion of the cable 91 pressed by the pressing surface 222 can be "stuck" in the positioning groove 224 to prevent the cable 91 from moving sideways and "falling off" from the pressing surface 222.

[0084] It should be understood that the positioning groove 224 can refer to Figure 5 The positioning groove 224 extends from the glue outlet 221 to the lower end of the pressing surface 222 , that is, the positioning groove 224 can “run through” the pressing surface 222 .

[0085] In some embodiments, the pressing surface 222 is located on one side of the glue outlet 221 ; the wiring portion 22 also includes: a glue spreading structure 225 for smoothing the hot melt adhesive 93 flowing out of the glue outlet 221 , the glue spreading structure 225 is located on the side of the glue outlet 221 away from the pressing surface 222 , and is adjacent to the glue outlet 221 .

[0086] As one embodiment of the present disclosure, refer to Figure 2 , Figure 5A glue structure 225 may also be provided on the wiring portion 22, and the glue structure 225 and the pressing surface 222 are respectively located on two opposite sides of the glue outlet 221; thus, referring to 7, the hot melt adhesive 93 (the hot melt adhesive 93 covering the cable 91) that flows out from the glue outlet 221 and adheres to the wiring carrier 92 can immediately contact the glue structure 225 while still in a molten state, thereby being "flattened" by the glue structure 225 to improve the appearance of the applied hot melt adhesive 93.

[0087] In some embodiments, the glue-spreading structure 225 is a curved protrusion.

[0088] Furthermore, the glue spreading structure 225 can be a "smooth" arc-shaped protrusion, thereby ensuring that the hot melt adhesive 93 can be spread evenly without scratching the cable 91 and the like.

[0089] For example, the glue structure 225 can be referenced Figure 5 "hemispherical" structure.

[0090] Second, refer to Figures 1 to 7 , the present disclosure provides a hot melt glue gun assembly for FTTR, which includes:

[0091] A hot melt glue gun 1, the hot melt glue gun 1 comprises a glue outlet pipe 11, and the glue outlet pipe 11 has a glue outlet end 111 for hot melt glue 93 to flow out;

[0092] Any one of the wiring heads 2 in the embodiments of the present disclosure is connected to the hot melt glue gun 1 .

[0093] Reference Figure 1 The hot melt glue gun assembly of the embodiment of the present disclosure includes a hot melt glue gun 1 and the above wiring head 2 installed on the hot melt glue gun 1. The hot melt glue gun assembly is used to complete the wiring and sealing of the cable 91 (such as optical fiber, especially the invisible optical fiber in FTTR) through one operation, that is, to achieve the placement of the cable 91 through one operation.

[0094] Among them, refer to Figure 3 The hot melt glue gun 1 includes a glue outlet tube 11 (such as a copper tube), and the glue outlet tube 11 has a glue outlet end 111 for allowing the hot melt glue 93 to flow out.

[0095] It should be understood that the hot melt glue gun 1 may also include other components such as a heater, a propulsion structure (such as a handle 19 that can push the molten hot melt glue 93 forward after being moved), etc., which will not be described in detail here.

[0096] It should be understood that when the wiring head is not installed, the separate hot melt glue gun 1 can also be used to perform other gluing operations, which will not be described in detail here.

[0097] In some embodiments, the hot melt glue gun 1 further comprises: a rotatable winding wheel 12 for winding the cable 91 .

[0098] Reference Figure 1 As one embodiment of the present disclosure, the hot melt glue gun 1 may also be provided with a rotatable winding wheel 12, and the cable 91 to be laid can be wound on the winding wheel 12, so that as the hot melt glue gun assembly moves, the winding wheel 12 can continuously rotate and release the cable 91, and the released cable 91 is pressed onto the wiring carrier 92 by the pressing surface 222 and sealed by the hot melt glue 93, thereby making the storage of the cable 91 more regular and convenient.

[0099] It should be understood that the specific form, position, etc. of the winding wheel 12 are various and will not be described in detail here.

[0100] It should be understood that it is also feasible if the hot melt glue gun 1 does not have a winding wheel and the cable 91 is stored through other structures, or if the hot melt glue gun 1 does not have a structure for storing the cable 91, etc.

[0101] The present disclosure has disclosed example embodiments, and although specific terms are employed, they are used and should be interpreted only in a general illustrative sense and not for limiting purposes.
