Description

Technical Field

[0001] The invention relates to the technical field of electric heating tapes, and in particular to an electric heating tape component that is easy to seal. Background Art

[0002] The self-regulating electric heating belt automatically reduces the heat (resistance increases), and when the temperature decreases, the belt will release more heat (resistance decreases). This self-regulating performance compensates for temperature changes at any time, preventing the belt from overheating and burning, while more strictly controlling the temperature of the heated object.

[0003] When installing the existing electric heating cables, the tail end needs to be sealed using a tail junction box. When two electric heating cables need to be connected, an intermediate junction box is required for wiring sealing. The two processing methods require the use of different junction boxes, and the same junction box cannot be used for different processing, which is troublesome. Summary of the invention

[0004] In order to solve the technical problems existing in the background technology, the present invention proposes an electric heating cable component which is easy to seal.

[0005] The present invention provides an electric heating tape assembly that is convenient for sealing treatment, comprising: an electric heating tape body, a treatment piece, the treatment piece comprising a shell 1, a shell 2, and a fixing unit for connecting the shell 1 and the shell 2, wherein the shell 1 and the shell 2 can be switched between a first state and a second state;

[0006] When the shell 1 and the shell 2 are in the first state, the processing element is used to perform sealing processing on the tail end of the electric heating belt body;

[0007] When the shell 1 and the shell 2 are in the second state, the processing member is used to seal the connection between the two electric heating belt bodies.

[0008] Preferably, a first opening is provided on shell one through which the end of the electric heating belt body can pass, and shell two can be adapted to be inserted into shell one. A guide block one is also installed in shell one, and a first accommodating groove is provided in guide block one for accommodating the tail end of the electric heating belt body, and the width and height of the first accommodating groove are greater than the width and height of the electric heating belt body.

[0009] Preferably, a second opening is provided on shell two for the passage of another end of the electric heating belt body, and two second accommodating grooves are also provided on guide block one, and the second accommodating grooves are open at one end away from the first accommodating grooves. When shell one and shell two are in the second state, they also include guide block two installed on shell two, and guide block two has the same structure as guide block one.

[0010] Preferably, the distance between the two second accommodating grooves increases in a direction away from the first accommodating groove.

[0011] Preferably, when the shell one and the shell two are in the first state, the outer wall of the shell two can abut against the guide block one.

[0012] Preferably, a first sealing block is fixed on guide block one and located between the outer ends of the two second accommodating grooves, and a second sealing block is fixed on guide block two. When shell one and shell two are in the second state, the first sealing block and the second sealing block abut against each other and their heights are equal to the height inside shell one, so as to separate the two copper core conductors of the same electric heating belt body located in the accommodating space formed by shell one and shell two.

[0013] Preferably, grooves for the second guide block to be adapted and plugged in are provided on the top wall and the bottom wall of the second shell.

[0014] Preferably, the fixing unit includes a screw and a nut adapted for use with the screw, and both the housing 1 and the housing 2 are provided with through holes for the screw to pass through.

[0015] Preferably, guide block one is detachably connected to shell one, and guide block two is detachably connected to shell two.

[0016] The electric heating belt assembly of the present invention can process the tail end of the electric heating belt body in different ways by means of the processing piece. When the second shell is located outside the first shell, the processing piece can be used to seal the connection between the two electric heating belt bodies. When the second shell is located inside the first shell, the processing piece can be used to seal the tail end of the electric heating belt body. The electric heating belt body can be sealed in different ways by the same processing piece, and the processing method is simpler.

[0017] The second sealing groove provided in the processing member of the present invention can make the tail ends of the two copper core wires originally arranged in parallel in the electric heating belt body arranged in an eight-shaped shape, so that the two copper core wires are separated from each other;

[0018] In the present invention, when the processing piece is used to connect two electric heating tape bodies, the first sealing block and the second sealing block abut against each other to separate the two spaces in the processing piece where two copper core conductors are placed respectively, thereby improving the sealing of the device and preventing the two copper core conductors from contacting and short-circuiting.

[0023] Reference Figure 1-4 The present invention proposes an electric heating tape assembly that is easy to seal, comprising: an electric heating tape body 1, a processing piece 2, wherein the processing piece 2 can be used to seal the tail end of the electric heating tape body 1, and can also be used as a connecting piece to connect two electric heating tape bodies 1, wherein the processing piece 2 comprises a shell 1 21, a shell 22, and a fixing unit 23 for connecting the shell 1 21 and the shell 2 22, wherein the shell 1 21 and the shell 2 22 can be switched between a first state and a second state;

[0024] When the shell 1 21 and the shell 2 22 are in the first state, the processing element 2 is used to perform sealing processing on the tail end of the electric heating belt body 1;

[0025] When the shell 1 21 and the shell 2 22 are in the second state, the processing element 2 is used to seal the connection between the two electric heating belt bodies 1.

[0026] Specifically, in the above embodiment, a first opening is provided on the shell 1 21 through which the end of the electric heating belt body 1 can pass, and a guide block 1 211 is also installed in the shell 1 21. A first receiving groove for receiving the tail end of the electric heating belt body 1 is provided in the guide block 1 211. The method for sealing the tail end of the electric heating belt body 1 using the processing element 2 is as follows:

[0027] First, the tail end of the electric heating cable body 1 is inserted into the first receiving groove in the guide block 1 211 through the first opening, and then the shell 22 is adapted to be inserted into the shell 1 21, and the shell 1 21 and the shell 2 22 are fixedly connected by the fixing unit 23, and then the sealant is injected into the first receiving groove. After the sealant solidifies, the tail end of the electric heating cable body 1 can be sealed. For details, please refer to Figure 2 .

[0028] The second shell 22 is provided with a second opening through which the end of another electric heating belt body 1 can pass, and the first guide block 211 is also provided with two second accommodating grooves both connected with the first accommodating groove, and the second accommodating groove is open at one end away from the first accommodating groove. When the first shell 21 and the second shell 22 are in the second state, they also include a second guide block 221 installed on the second shell 22, and the guide block 221 has the same structure as the guide block 1 211. On the basis of the above, the method of using the processing member 2 to seal the connection of the two electric heating belt bodies 1 is as follows:

[0029] Before connecting two electric heating tape bodies 1, firstly, the tail ends of the two electric heating tape bodies 1 are processed so that the tail ends of the copper core wires in the two electric heating tape bodies 1 are leaked out, and then the tail end of one electric heating tape body 1 is extended into the first receiving groove on the guide block 1 211 through the first opening, and the two copper core wires leaked from the electric heating tape body 1 are respectively passed through the second receiving groove on the guide block 1 211, and the tail end of the other electric heating tape body 1 is extended into the first receiving groove on the guide block 221 through the second opening, and the two copper core wires leaked from the electric heating tape body 1 are respectively passed through the second receiving groove on the guide block 221, and then the two copper core wires on the two electric heating tape bodies 1 are respectively connected together, and then the shell 1 21 and the shell 2 22 are fixedly connected together through the fixing unit 23, and the shell 2 22 is located outside the shell 1 21, for details, refer to Figure 4 , glue is injected into the first receiving grooves on the guide block 1 211 and the guide block 2 221, which can seal the first receiving grooves and fix the electric heating belt body 1 and the shell 1 21 or the shell 2 22 at the same time.

[0030] In the above embodiment, the distance between the two second accommodating grooves increases in the direction away from the first accommodating groove, forming an eight-shaped shape, so that the tail ends of the two copper core wires on the electric heating belt body 1 are separated, reducing the possibility of the two being too close to each other and causing a short circuit in the electric heating belt body 1.

[0031] It needs to be further explained that when the processing piece 2 is used to seal the tail end of the electric heating tape body 1, that is, the shell 1 21 and the shell 2 22 are in the first state, in order to further improve the sealing of the electric heating tape body 1 by the processing piece 2, the shell 2 22 can be adapted to be inserted into the shell 1 21, and the outer wall of the shell 22 can abut against the guide block 1 211, and the width of the second opening is smaller than the distance between the outer ends of the two second receiving grooves, so that the outer wall of the shell 22 closes the outer end of the second receiving groove, and the outer wall of the guide block 1 211 can close the second opening on the shell 22, and the two rely on each other for sealing.

[0032] In order to further improve the sealing performance of the processing element 2 when connecting two electric heating tape bodies 1 and avoid the short circuit caused by the contact of the two copper core wires on the electric heating tape body 1, a first sealing block 212 is fixed on the guide block 211 and located between the outer ends of the two second accommodating grooves, and a second sealing block 222 is fixed on the guide block 221. When the shell 1 21 and the shell 2 22 are in the second state, the first sealing block 212 and the second sealing block 222 abut against each other and their heights are equal to the height inside the shell 1 21, so as to separate the two copper core wires of the same electric heating tape body 1 located in the accommodating space formed by the shell 1 21 and the shell 2 22.

[0033] In order to reduce the replacement and maintenance costs of the electric heating belt body 1 and the processing element 2, the guide block 1 211 is detachably connected to the shell 1 21, and the guide block 2 221 is detachably connected to the shell 2 22.

[0034] The top wall and the bottom wall of the second housing 22 are both provided with grooves for the second guide block 221 to fit in and plug into.

[0035] In the above embodiment, the fixing unit 23 includes but is not limited to screws and nuts adapted for use with the screws, and both the housing 1 21 and the housing 2 22 are provided with through holes for the screws to pass through.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
