For the purpose of describing the embodiments and benefits of the present application, the present application is briefly introduced herein to the structure of a prior art electrocardiographic monitoring device. As shown in fig. 1, which is a vehicle-mounted electrocardiographic monitoring device in the prior art, two electrodes 11 of the electrocardiographic monitoring device are respectively attached to a user, and after the electrodes 11 are attached to the skin of the human body, electrocardiographic signals of the human body can be acquired, and are subjected to calculation processing by a processor 13 and then transmitted to a display device 14, and finally, a dynamic electrocardiographic curve is displayed on the display device 14.

The inventor of the present application has found that in the prior art, the electrocardiographic monitoring device is rarely used in a vehicle, and one reason for this is that the electrode 11 is connected to the processor 13 through the conductive connecting wire 12, and the processor 13 has a circuit board (not shown in the figure) inside, and the circuit board and the conductive connecting wire 12 are electrically connected by direct welding. If the conductive connecting wire is applied to the cockpit of a vehicle, after the vehicle is strongly impacted, the conductive connecting wire 12 is easily pulled by external force, so that the risk that welding points of the conductive connecting wire 12 and a circuit board in the processor 13 are pulled off is caused.

In view of the above, as shown in fig. 2 to 3, the present application provides an electrode harness structure, so that the conductive connecting wire 12 is fixedly disposed on the tensile structure 23, and the tensile structure 23 is fixedly disposed on the external electronic control box 20. When the vehicle is strongly impacted and the conductive connection line 12 is pulled, the tensile structure 23 can bear the pulling force of the conductive connection line 12, so that the risk that the conductive connection line 12 is separated from the circuit board and a welding spot is pulled off is avoided.

It is understood that the electrode harness structure of the present application can be applied to any electrical control box having a risk of pulling the conductive connection line 12, besides the electrocardiograph monitoring device.

As shown in fig. 2 to 3, a first embodiment of the present application proposes an electrode harness structure for an electrocardiograph monitoring device, the electrode harness structure including: the tensile structure 23 is used for fixedly connecting with the external electronic control box 20; one end of the conductive connecting line 12 is connected with the external electrode 11, and the other end of the conductive connecting line 12 is fixedly arranged on the tensile structure 23; the tensile structure 23 penetrates through the external electronic control box 20, and the other end of the conductive connection line 12 penetrates through the tensile structure 23 to enter the external electronic control box 20 and is connected with a circuit board arranged inside the external box 20.

The tensile structure 23 of the present application is mainly used for fixing the conductive connection line 12, for example, the conductive connection line 12 may be connected to the tensile structure 23 by external glue or the like, or the wire harness sheath of the conductive connection line 12 may be directly formed integrally with the tensile structure 23.

A tensile structure 23 may be disposed on the external electronic control box 20, and the tensile structure 23 may be integrally formed with the external electronic control box 20, or may be a detachable structure, which is not limited herein. The tensile structure 23 is used for fixedly mounting the conductive connecting wire 12 of the electrocardiogram monitoring device. Tensile structure 23 may be provided on any one of the side walls of outer control box 20 (it should be noted that the top and bottom walls in the conventional sense are both referred to herein as the side walls). The tensile structure 23 penetrates through the side wall of the external electronic control box 20, so that the conductive connecting wire 12 can penetrate through the tensile structure 23 and then extend into the external electronic control box 20, and is connected with the circuit board.

In the above-mentioned structure, receive strong striking back when the vehicle, external force makes conductive connection line 12 receive easily and pulls, because conductive connection line 12 and tensile structure 23 fixed connection, consequently, the outside that conductive connection line 12 received is pulled power and can be transmitted to tensile structure 23 on, bear the pulling force of conductive connection line 12 by tensile structure 23, the tensile strength of conductive connection line 12 has been strengthened indirectly, avoid appearing the risk that the solder joint was pulled off between conductive connection line 12 and the inside circuit board of box body 21.

Illustratively, the sheath of the conductive connecting wire 12 and the tensile structure 23 are welded together to form a unitary structure. In this embodiment, since the conductive connection line 12 is easily pulled by a strong impact on the vehicle, in order to improve the tensile strength of the conductive connection line 12, the harness sheath of the conductive connection line 12 may be welded to the tensile structure 23 to form an integral structure. After the vehicle receives strong striking, the outside that electrically conductive connecting wire 12 received is dragged power and can directly transmit to tensile structure 23 on, bears the pulling power of electrically conductive connecting wire 12 by tensile structure 23, has directly strengthened the tensile strength of electrically conductive connecting wire 12, avoids appearing the risk that the solder joint was pulled off between electrically conductive connecting wire 12 and the inside circuit board of box body 21.

In the technical scheme of the embodiment, the tensile structure 23 and the wire harness outer skin of the conductive connecting wire 12 are welded together through a wire harness plastic-coating process, and the tensile structure 23 is fixed on the box body 21 in a clamping manner.

It is understood that the plastic-coated material of the tensile structure 23 may be a PVC material, so as to be better welded with the outer skin material of the conductive connecting wire 12; in addition, the plastic-coated material made of PVC material has the hardness of more than 70 and the tensile strength of more than 100N, so that the tensile structure 23 is safer and more reliable.

For convenience of describing the beneficial effects of the present embodiment, the following is specifically illustrated as an example:

as shown in fig. 1 and 4, the electrocardiograph monitoring device has a positive electrode 11 and a negative electrode 11, and the positive electrode 11 and the negative electrode 11 are respectively connected with a processor 13 thereof through a conductive connecting wire 12. In order to improve the production efficiency, the outer shielding wires of the conductive connecting wires 12 of the positive electrode 11 and the negative electrode 11 can be stripped to a length of 16 mm, and a heat shrinkable tube 123 is sleeved to form an electrode wire grounding wire 121, and the core wires of the conductive connecting wires 12 are pulled out to be used as signal wires 122.

The outer sheath of the signal line 122 was pulled out to expose the conductor 3mm in length. The sheath shielding layer of the electrode grounding wire 121 is pulled out to expose the conductor with the length of 5mm, so that the process requirement of perforation welding is met. Since the heat shrinkable tube 123 cannot pass through the welding hole, the height of the outcrop portion after threading is less than 1.4mm and the diameter of the threading hole is 1.5mm.

The

electrode ground wires

121 and 122 are connected to the circuit board by soldering. At this time, the circuit board and the signal lines of the positive electrode 11 and the negative electrode 11 form a current path, so that the anti-interference capability of the conductive connecting line 12 is enhanced.

It will be appreciated that the AWG22 coaxial line can be selected as the conductive connecting line 12, thereby better avoiding signal interference problems.

In view of the above, the present application provides an electrical control box 20, so as to fix the conductive connection line 12 on the tensile structure 23 of the electrical control box 20. When the vehicle is strongly impacted and the conductive connection line 12 is pulled, the tensile structure 23 can bear the pulling force of the conductive connection line 12, so that the risk that the solder joint is pulled off when the conductive connection line 12 is separated from the circuit board is avoided.

It is understood that the electrical control box 20 of the present application can be applied to any device that risks pulling the electrically conductive connection wire 12, in addition to the electrocardiograph monitoring device.

As shown in fig. 2 to 3, the first embodiment of the present application proposes that the electrical control box includes the above-described electrode harness structure; and

In the electrical control box 20 of the present application, the box body 21 is hollow inside to form a cavity with a holding function. The interior of the box body 21 can be used for fixing a central control component of the electrocardiograph monitoring device, such as a circuit board for fixing a central control group, and the circuit board can be fixedly installed in the box body 21 through screws; in addition, the box 21 can protect the central control component from the external environment, for example, prevent the surface of the circuit board from being deposited with dust.

Tensile structure 23 may be disposed on box 21, tensile structure 23 may be formed integrally with box 21, or both may be detachable structures, which is not limited herein. The tensile structure 23 is used for fixedly mounting the conductive connecting wire 12 of the electrocardiogram monitoring device. Tensile structure 23 may be provided on any one of the side walls of case 21 (note that the top and bottom walls in the conventional sense may be referred to as the side walls collectively herein). The tensile structure 23 penetrates through the sidewall of the box body 21, so that the conductive connecting wire 12 can penetrate through the tensile structure 23 and then extend into the box body 21, and is connected with the circuit board.

In the above-mentioned structure, receive strong striking back when the vehicle, external force makes conductive connection line 12 receive to drag easily, because conductive connection line 12 and tensile structure 23 fixed connection, consequently, the outside that conductive connection line 12 received is dragged power and can be transmitted to tensile structure 23 on, bear the power of dragging of conductive connection line 12 by tensile structure 23, the indirect tensile strength who has strengthened conductive connection line 12, the risk that the solder joint was pulled off appears between the circuit board of avoiding conductive connection line 12 and box body 21 inside.

It is understood that the connection between the tensile structure 23 and the conductive connection line 12 may be:

1. the conductive connecting line 12 is fixedly connected with the tensile structure 23 through auxiliary tools such as glue, bonding glue and the like;

2. the outer skin of the conductive connecting wire 12 and the tensile structure 23 are welded to form an integral structure, so that the conductive connecting wire 12 is fixedly connected to the tensile structure 23;

3. the tensile structure 23 is integrally extended to form a tubular sheath, the conductive connecting wire 12 is arranged in the tubular sheath, and the tubular sheath is fixedly connected with the conductive connecting wire 12 through a heat shrink tube or an OT terminal, so that the effect that the conductive connecting wire 12 is fixedly connected with the tensile structure 23 is achieved;

the above list only 3 ways of fixedly connecting the conductive connecting wires 12 to the tensile structure 23, but does not represent only 3 ways.

It is also worth mentioning that the tensile structure 23 may be made of a material having a certain elasticity. Receive strong striking back when the vehicle, external force makes conductive connection line 12 receive to drag easily, and conductive connection line 12 receives outside drag power transfer to tensile structure 23 on back, tensile structure 23 bears conductive connection line 12 drag power to the buffering receives drags power, has strengthened conductive connection line 12's tensile strength indirectly, avoids appearing the risk that the solder joint was pulled off between conductive connection line 12 and the inside circuit board of box body 21.

In addition, have certain elastic tensile structure 23, receive the instant of dragging at conductive connection 12, tensile structure 23 atress can produce deformation, prevents to produce the rigidity between conductive connection 12 and the tensile structure 23 and drags to and, can avoid appearing the risk that the solder joint was pulled off between conductive connection 12 and the inside circuit board of box body 21.

Illustratively, the box body 21 is provided with a through hole a;

the tensile structure 23 is provided on the through-hole a, and the movement of the tensile structure 23 in the axial direction of the through-hole a is blocked by the side wall of the case 21 forming the through-hole a.

In this embodiment, the box 21 and the tensile structure 23 may be detachably disposed. As an example, a through hole a may be formed on a sidewall of the case body 21, and the tensile structure 23 may be fixedly installed inside the through hole a. When the central control component of the electrocardiogram monitoring device needs to be installed, the circuit board is fixedly installed inside the box body 21, and then the tensile structure 23 fixedly provided with the conductive connecting wire 12 is installed inside the through hole a, so that the purpose is to introduce the wire connecting wire into the box body 21 from the outside of the box body 21 and connect the wire connecting wire with a welding spot on the circuit board.

It is understood that the conductive connection line 12 is easily pulled by an external force when the vehicle is strongly impacted. Because the conductive connecting line 12 is fixedly connected with the tensile structure 23, an external pulling force applied to the conductive connecting line 12 can be transmitted to the tensile structure 23, and the tensile structure 23 bears the pulling force of the conductive connecting line 12 and generates a small amount of deformation to buffer the pulling force.

It should be noted that, in the process of applying a force to the tensile structure 23, the movement of the tensile structure 23 in the axial direction of the through hole a is blocked by the sidewall of the box body 21 forming the through hole a, so as to indirectly enhance the tensile strength of the conductive connection line 12 and avoid the risk of the solder joint being pulled off between the conductive connection line 12 and the circuit board inside the box body 21.

It can be understood that the solder joints of the circuit board are located on the upper surface of the copper-clad plate, and after the circuit board is fixed inside the box 21, the conductive connecting wires 12 passing through the tensile structures 23 need to extend to the upper surface of the circuit board and be connected to the solder joints on the upper surface of the circuit board. In view of this, in order to facilitate the arrangement of the flat cable of the conductive connecting wires 12 inside the box body 21, the through hole a may be opened on the sidewall of the box body 21 higher than the position where the circuit board is mounted, or the through hole a may be opened on the sidewall of the box body 21 facing the upper surface of the circuit board, so as to avoid that the conductive connecting wires 12 inside the box body 21 are wound inside the box body 21 due to the need to bypass a specific position, which wastes too many conductive connecting wires 12 and increases the production cost.

Illustratively, the case 21 is open on one side to form an opening;

the electrical control box 20 further includes a cover 22, and the cover 22 covers the opening;

a first notch B1 is formed at a portion of the cover 22 contacting the case body 21, a second notch B2 is formed at a portion of the case body 21 contacting the cover 22, and the first notch B1 and the second notch B2 are engaged with each other to form a through hole a.

In this embodiment, the installation stability of the tensile structure 23 on the shell is further enhanced. As shown in fig. 5 to 6, a first notch B1 may be formed at a portion of the cover 22 contacting the case body 21, a second notch B2 may be formed at a portion of the case body 21 contacting the cover 22, and after the case body 21 and the cover 22 are fitted, the first notch B1 and the second notch B2 are combined to form the through hole a. When installing the circuit board, fix the circuit board inside box body 21 earlier, for example, the circuit board is installed in the bottom of box body 21, and is located the opening, and tensile structure 23 sets up in second breach B2 towards one side of box body 21 bottom, and after lid 22 lid closed the opening, first breach B1 and tensile structure 23 towards one side block of lid 22 are connected, and box body 21 and lid 22 both press from both sides tensile structure 23 tightly, make the stable setting of tensile structure 23 in the through-hole A that first breach B1 and second breach B2 amalgamation formed.

It can be understood that, when the circuit board is fixedly mounted at the bottom of the box body 21, the second notch B2 is located between the circuit board and the cover body 22; when the circuit board is fixedly mounted on the bottom of the cover 22, the first notch B1 is located between the circuit board and the bottom of the box 21.

Exemplarily, the tensile structure 23 is provided with a limiting groove C, and a side wall forming the through hole a is sleeved on the limiting groove C, so that the tensile structure 23 is clamped on the through hole a.

In this embodiment, as shown in fig. 8, in order to facilitate quick installation of the tensile structure 23 on the box body 21, a limiting groove C may be formed on the surface of the tensile structure 23 opposite to the box body 21 and/or the cover 22. When installing tensile structure 23, place tensile structure 23 in through-hole A, and form through-hole A's lateral wall cover on spacing groove C to tightly block tensile structure 23 on through-hole A.

In order to enable the groove wall of the limiting groove C to be stably connected with the side wall forming the through hole A, a structure with certain friction force, such as a friction bulge, a friction texture and the like, can be arranged on the groove wall of the limiting groove C and/or the side wall forming the through hole A, so that the groove wall of the limiting groove C and the side wall forming the through hole A are attached and fastened more tightly. After the vehicle receives strong striking, the outside that electrically conductive connecting wire 12 received is dragged power and can be transmitted to tensile structure 23 on, and tensile structure 23 bears the pulling power of electrically conductive connecting wire 12, and the cell wall of spacing groove C and the frictional force between the lateral wall that forms through-hole A can reduce the deflection of tensile structure 23, have strengthened electrically conductive connecting wire 12's tensile strength indirectly, avoid appearing the risk that the solder joint was pulled off between electrically conductive connecting wire 12 and the inside circuit board of box body 21.

Illustratively, the portions of case 21 and/or cover 22 that contact tensile structure 23 form a fixed structure (not shown), and tensile structure 23 includes:

the first side wall 231 is arranged on one side of the through hole A, the first side wall 231 extends from the tensile structure 23 to the through hole A and is attached to the fixing structure, and a limiting groove C is formed on the surfaces of the first side wall 231 and the tensile structure 23 corresponding to the edge position of the through hole A;

wherein, after the cover 22 is adapted to cover the box 21, the first sidewall 231 is located inside the box 21.

In this embodiment, as shown in fig. 9, the cross section of the limiting groove C is formed in an L-shaped structure in the plane direction of the opening of the case body 21. First sidewall 231 of tensile structure 23 is located in the opening, and after tensile structure 23 is installed in through-hole a, first sidewall 231 and the fixed structure of box body 21 are connected to each other, and first sidewall 231 is used for bearing external pulling force. Specifically, the main portion of the tensile structure 23 may be fixedly installed in the through hole a, so that a compressive force is formed between the surface of the tensile structure 23 and the wall of the through hole a, thereby fixing the tensile structure 23. At the same time, the first sidewall 231 is tightly attached to the fixed structure of the case 21 and/or the cover 22. After the vehicle is strongly impacted, the external pulling force applied to the conductive connecting line 12 can be transmitted to the tensile structure 23, the tensile structure 23 bears the pulling force of the conductive connecting line 12, the first side wall 231 equally divides the external load force on the fixed structure, the main body of the tensile structure 23 is prevented from being pulled away from the box body 21 and/or the cover body 22, the tensile strength of the conductive connecting line 12 is indirectly enhanced, and the risk that welding spots are pulled off between the conductive connecting line 12 and a circuit board inside the box body 21 is avoided.

It can be understood that, if the tensile structure 23 has a certain elasticity, after the tensile structure 23 bears the pulling force of the conductive connection line 12, the first sidewall 231 equally divides the external load force on the fixed structure, and meanwhile, the first sidewall 231 is slightly deformed when being stressed, so as to further buffer the external pulling force. Simultaneously in the moment that electrically conductive connecting wire 12 received to be dragged, first lateral wall 231 atress can produce micro-deformation, avoids producing the rigidity in the twinkling of an eye between electrically conductive connecting wire 12 and tensile structure 23 and drags, avoids appearing the risk that the solder joint was pulled off between electrically conductive connecting wire 12 and the inside circuit board of box body 21.

Illustratively, the portions of case 21 and/or cover 22 that contact tensile structure 23 form a fixed structure, and tensile structure 23 includes:

a first sidewall 231 disposed at one side of the through-hole a;

the second side wall 232 is arranged on the other side of the through hole a, the first side wall 231 and the second side wall 232 are arranged in opposite directions, the first side wall 231 and the second side wall 232 extend from the tensile structure 23 to the through hole a, the first side wall 231 is attached to the fixed structure, and a limiting groove C is formed on the surfaces of the first side wall 231, the second side wall 232 and the tensile structure 23 corresponding to the edge position of the through hole a;

wherein, after the cover 22 is adapted to cover the box 21, the first sidewall 231 is located in the box 21.

In this embodiment, as shown in fig. 10, a first sidewall 231 and a second sidewall 232 extend from two sides of the tensile structure 23 in the axial direction of the through hole a, the first sidewall 231 and the second sidewall 232 are disposed at an interval, a limiting groove C is formed on the surface of the first sidewall 231, the second sidewall 232 and the tensile structure 23 corresponding to the edge position of the through hole a, and a cross section of the limiting groove C forms a U-shaped structure in the plane direction of the opening of the box body 21. In order to improve the stability of the installation of the tensile structure 23, the distance between the first sidewall 231 and the second sidewall 232 can be slightly smaller than the thickness of the sidewall of the box body 21 forming the through hole a, so that the edge of the through hole a is tightly clamped between the first sidewall 231 and the second sidewall 232, and the tensile structure 23 is prevented from being subjected to force and shifting, even being separated from the through hole a.

The first sidewall 231 of this embodiment is further disposed in the opening, after the tensile structure 23 is installed in the through hole a, the first sidewall 231 is connected with the fixing structure of the box body 21, and the first sidewall 231 is used for bearing an external pulling force. Specifically, the main portion of tensile structure 23 may be fixedly mounted in through-hole a, such that a compressive force is formed between the surface of tensile structure 23 and the wall of through-hole a, thereby fixing tensile structure 23 and tightly securing first sidewall 231 to the fixed structure. After the vehicle is strongly impacted, the external pulling force applied to the conductive connecting line 12 can be transmitted to the tensile structure 23, the tensile structure 23 bears the pulling force of the conductive connecting line 12, the first side wall 231 equally divides the external load force on the fixed structure, the main body of the tensile structure 23 is prevented from being pulled away from the box body 21 and/or the cover body 22, the tensile strength of the conductive connecting line 12 is indirectly enhanced, and the risk that welding spots are pulled off between the conductive connecting line 12 and a circuit board inside the box body 21 is avoided.

It can be understood that, if the tensile structure 23 has a certain elasticity, after the tensile structure 23 bears the pulling force of the conductive connection line 12, the first sidewall 231 equally divides the external load force on the fixed structure, and meanwhile, the first sidewall 231 is slightly deformed when being stressed, so as to further buffer the external pulling force.

In addition, in the moment that the conductive connecting line 12 is pulled, the first side wall 231 is stressed to generate micro deformation, so that rigid pulling between the conductive connecting line 12 and the tensile structure 23 is avoided, and the risk that the welding spot is pulled off between the conductive connecting line 12 and the circuit board is prevented.

As a modified structure, in order to facilitate the installation of the tensile structure 23 in the through hole a, a rounding or chamfering process may be performed on a side of the second side wall 232 away from the first side wall 231, so that the side of the second side wall 232 away from the first side wall 231 is smaller than the diameter of the through hole a. When the tensile structure 23 is installed, one side of the second sidewall 232, which is far away from the first sidewall 231, extends into the through hole a first, and then the tensile structure 23 can be pressed into the through hole a quickly only by forcibly pushing the first sidewall 231 to move toward the through hole a, so that the sidewall forming the through hole a is clamped in the inner limit groove C.

When the vehicle is strongly impacted, the movement of the tensile structure 23 in the axial direction of the through hole a is blocked by the side wall of the box body 21 forming the through hole a, so that the tensile strength of the conductive connecting line 12 is indirectly enhanced, and the risk that a welding spot is pulled off between the conductive connecting line 12 and a circuit board in the box body 21 is avoided.

Illustratively, a first projection of the first sidewall 231 on the sidewall of the box body 21 covers a second projection of the second sidewall 232 on the sidewall of the box body 21, and the area of the first projection is larger than that of the second projection.

In this embodiment, after the vehicle is subjected to a strong impact, in order to further increase the strength of the uniform load-sharing force of the first sidewall 231, the projection area of the first sidewall 231 in the axial direction of the through hole a needs to be set larger. For example, the projection of the first sidewall 231 on the sidewall of the box body 21 is set as a first projection, and the projection of the second sidewall 232 on the sidewall of the box body 21 is set as a second projection, wherein the first projection covers the second projection in the same projection direction, and the area of the first projection is larger than that of the second projection. Receive strong striking back when the vehicle, the outside that electrically conductive connecting line 12 received is dragged power and can be transmitted to tensile structure 23 on, tensile structure 23 bears the pulling power of electrically conductive connecting line 12, first lateral wall 231 has enough big area and can equally divide outside bearing capacity on fixed knot constructs, avoid tensile structure 23 main part to be pulled away box body 21 and/or lid 22, the indirect tensile strength who has strengthened electrically conductive connecting line 12, the risk that the solder joint was pulled off appears between electrically conductive connecting line 12 and the inside circuit board of box body 21.

Illustratively, the surface of the first sidewall 231 facing the second sidewall 232 is provided with a spike-shaped protrusion 233, and the spike-shaped protrusion 233 is obliquely arranged toward the central axis direction of the tensile structure 23;

the surface of the fixing structure, which is attached to the first sidewall 231, is provided with a slot (not shown), into which the spike-shaped protrusion 233 is inserted.

After the tensile structure 23 is disposed in the through hole a, the first sidewall 231 is attached to the surface of the fixing structure, and at this time, the plurality of spine-shaped protrusions 233 are correspondingly inserted into the plurality of slots, so that the first sidewall 231 is only clamped to the fixing structure.

When the vehicle is strongly impacted, the external pulling force applied to the conductive connection line 12 can be transmitted to the tensile structure 23, the tensile structure 23 bears the pulling force of the conductive connection line 12, and the first sidewall 231 distributes the received pulling force to the pointed protrusions 233. Since each of the spine-shaped protrusions 233 is inclined toward the central axis of the tensile structure 23, when the tensile structure 23 is pulled, the central portion of the first sidewall 231 is first forced to deform toward the inside of the through hole a. If the pulling force is large enough, the first side wall 231 can be sunken towards the direction of the through hole A, and the plurality of pointed protrusions 233 can be deformed under stress, so that the groove walls of the clamping groove are tightly hooked, the first side wall 231 is prevented from being sunken towards the direction of the through hole A, the main body of the tensile structure 23 cannot be pulled away from the box body 21 and/or the cover body 22, the tensile strength of the conductive connecting line 12 is indirectly enhanced, and the risk that the welding point is pulled off between the conductive connecting line 12 and the circuit board is avoided.

In this embodiment, as shown in fig. 12, protrusions or textures for increasing surface friction may be provided on the surface of the spike-shaped protrusions 233 to form the rough surface 234. When the spine-shaped protrusion 233 is disposed in the slot, the rough surface 234 of the spine-shaped protrusion 233 abuts against the slot wall of the slot, so as to improve the sliding friction between the spine-shaped protrusion 233 and the slot wall, and the spine-shaped protrusion 233 can be more stably clamped in the slot.

A snap structure may be provided between the case 21 and the cover 22. For example, a fixing block 212 is disposed on the side of the box body 21 facing the cover body 22, a fastening groove D is formed on the fixing block 212 to form a fastening member of a fastening structure, and a fastening protrusion 213 is correspondingly disposed on the side of the cover body 22 facing the box body 21. The fixing blocks 212 correspond to the locking protrusions 213 one by one, and the fastening grooves D can be engaged with the locking protrusions 213 after the cover 22 is precisely closed on the box body 21.
