The other end of the electrocardio-bus electrode 2 is electrically connected with the conductive core of the cable 5 by adopting a hot melting technology. The conductive core of the cable 5 is also made of a non-metallic conductive material, in this embodiment, the electrocardiograph bus electrode 2 and the conductive core of the cable 5 are both made of a conductive plastic material, the conductive plastic material is a functional polymer material which is processed by mixing resin and a conductive substance in a plastic processing manner, and the material is an existing material. The other end of the cable 5 is electrically connected with external equipment.

as shown in fig. 1 and 2, an arc-shaped clamping groove 121 is further disposed on the surface of the lower shell 12 above the socket 120, a clamping protrusion 21 engaged with the arc-shaped clamping groove 121 is disposed at the bottom of the electrocardiograph electrode 2, and the clamping protrusion 21 is clamped into the clamping groove 121 to perform a positioning function. In addition, an upper positioning hole 22 and a lower positioning hole (not shown) are respectively formed above and below the electrocardiograph electrode 2, an upper positioning post 110 engaged with the upper positioning hole 22 is formed on the inner surface of the upper case 11, and a lower positioning post (not shown) engaged with the lower positioning hole is formed on the inner surface of the lower case 12. After the upper shell 11 and the lower shell 12 are fixed by ultrasonic welding, the clamping protrusion 21 of the electrocardiograph mother electrode 2 is embedded into the clamping groove 121, the upper positioning column 110 is inserted into the upper positioning hole 22, and the lower positioning column is inserted into the lower positioning hole, so that the electrocardiograph mother electrode 2 is fixedly connected with the shell 1, and cannot shift or shake.

An elastic part used for tripping the existing electrocardio-electrode buckle usually needs a rotating shaft, and the rotating shaft is easy to wear and cause looseness or breakage after long-term use, so that faults are frequent when the electrocardio-electrode buckle is used. In order to solve the problem, in the elastic body 3 disclosed in this embodiment, as shown in fig. 2, the bottom end of the elastic body 3 is provided with an elastic bending section 30, and the elastic bending section 30 may be in a spring shape, a wave shape, or the like, and can generate elastic deformation to store energy. The middle section 31 of the elastic body 3 is positioned below the socket 120 and is opposite to the groove 20 of the electrocardio female electrode 2, the middle section 31 is provided with a clamping plate 310, and one side of the clamping plate 310 facing the socket 120 is in a circular arc shape matched with the electrocardio male electrode. The distal end of the elastic body 3 extends above the electrocardiograph main electrode 2 by passing over the socket 120 and extends in the direction outside the housing 1, and a push button 4 is provided at the distal end. An opening 122 for the key 4 to pass through is formed in the side wall of the lower shell 12, and the top edge of the key 4 cannot pass through the opening 122, so that the limiting function of pressing down is achieved.

When the shadowless electrocardio-electrode buckle is not in butt joint with the electrocardio-male electrode, the elastic bending section 30 does not generate elastic deformation, the clamping plate 310 stays on the surface of the socket 120, and the electrocardio-male electrode is blocked by the clamping plate 310 and cannot be inserted into the socket 120. When the key 4 is pressed, the elastic bending section 30 is compressed, the middle section 31 moves downwards until the edge of the clamping plate 310 is flush with the edge of the socket 120, the electrocardio male electrode is inserted at the moment, the key 4 is released again, the middle section 31 rebounds and rises under the action of the elastic bending section 30, and the electrocardio male electrode is pressed into the groove 20 of the electrocardio female electrode 2 by the clamping plate 310, so that the electrocardio male electrode is communicated with the electrocardio female electrode 2. The end part of the electrocardio male electrode is provided with a self-locking groove with the width matched with that of the middle section 31, and after the electrocardio male electrode is inserted into the socket 120, the middle section 31 is clamped into the self-locking groove, so that the electrocardio male electrode can be prevented from being accidentally taken off. When the device needs to be disassembled, the key 4 is pressed, the middle section 31 moves downwards until the middle section is separated from the electrocardio male electrode, and then the electrocardio electrode buckle is moved to be separated from the electrocardio male electrode.

In order to prevent the elastic body 3 from being displaced inside the casing 1, the inner surface of the side wall of the lower casing 12 is further provided with a groove 123, the tail end of the elastic body 3 is inserted into the groove 123, and when the elastic body 3 is compressed, the groove 123 can prevent the elastic body 3 from sliding along the inner wall of the lower casing 12, thereby achieving the positioning effect.

In order to solve this problem, in the present embodiment, the observation window 6 is opened on the surface of the upper case 11. The observation window 6 is arranged right opposite to the socket 120, the transparent sealing cover 61 covering the observation window 6 is fixed on the surface of the upper shell 11, and whether the contact between the electrocardio female electrode 2 and the electrocardio male electrode is good or not can be visually observed through the transparent sealing cover 61, so that the electrocardio detection quality is improved. The upper case 11 has a recess 111 on its surface, which is matched with the transparent cover 61 in shape, and the transparent cover 61 is fitted into the recess 111 and fixed by adhesive.

example two

The embodiment is an improvement of the previous embodiment, the existing electrocardio-electrode buckle cable 5 directly extends out from the interior of the shell 1, so that tiny relative movement between the cable 5 and the shell 1 is inevitable in the using process, the pulling force is conducted to the connection position of the electrocardio-bus electrode 2, and poor contact or disconnection between the cable 5 and the electrocardio-bus electrode 2 is easily caused. To solve this problem, in the embodiment, as shown in fig. 3, the tail of the housing 1 is provided with a wiring groove 124, and the wiring groove 124 extends to the tail of the housing in a curve like a wave.

Specifically, in the embodiment of the present application, as shown in fig. 3, the wiring groove 124 is disposed on the inner surface of the rear portion of the housing 1, and has one end near the terminal of the electrocardiograph bus electrode 2 and the other end extending along a wave-shaped track in a horizontal plane toward the rear portion of the housing 1. The wiring groove 124 comprises two wavy guard plates arranged on the inner surface of the tail part of the upper shell 11 and two corresponding wavy guard plates arranged on the inner surface of the tail part of the lower shell 12, the guard plates protrude out of the inner surface of the shell 1 by a certain height, the two guard plates positioned on the upper shell 11 are opposite to the two guard plates positioned on the lower shell 12, therefore, when the upper shell 11 is buckled with the lower shell 12, the wiring groove 124 formed by splicing the guard plates is formed, and the space between the two guard plates is used for wiring.

By adopting the structural design, when the cable 5 is subjected to external tension, the positive pressure of the cable on the surface of the protection plate can be increased, so that the tension is converted into the friction force between the cable 5 and the protection plate, the tension cannot be further transmitted through the wiring groove 124, and the condition that the external tension damages the electric connection between the cable 5 and the electrocardio bus electrode 2 is avoided.

In another embodiment of the present application, as shown in fig. 4, the cabling channel 124 may also extend towards the rear of the housing 1 in a wave shape in a vertical plane. Specifically, a plurality of annular first ribs 112 are formed downward on the inner surface of the upper shell 11, the first ribs 112 are arranged at intervals toward the tail of the housing 1, and second ribs 125 corresponding to the first ribs 112 one to one are formed on the inner surface of the lower shell 12. The heights of two adjacent first convex edges 112 are different, and the end surfaces of the first convex edges 112 are in an inwards concave arc shape, so that the end parts of the first convex edges 112 are integrally connected to form a wave shape with an undulate height in a vertical plane; correspondingly, the heights of two adjacent second protruding ribs 125 are different, and the end surfaces of the second protruding ribs 125 are concave circular arcs. The opposing first ribs 112 and second ribs 125 are complementary in height such that the gap between the ends of each opposing first rib 112 and second rib 125 is of uniform size, such that a raceway 124 is formed between the ends of the first ribs 112 and second ribs 125.

By adopting the structural design, when the cable 5 is subjected to external tension, the positive pressure applied by the end surfaces of the first rib 112 and the second rib 125 is increased, so that the friction force between the wiring groove 124 and the cable 5 is increased, the tension is applied to the wiring groove 124 and stops, and the connection between the cable 5 and the electrocardiogram bus electrode 2 cannot be further influenced.

Further, in order to avoid slipping from the hand during the operation of the electrocardio-electrode buckle, the surface of the key 4 is provided with a first anti-slip area 41, the side surface of the shell 1 is provided with a second anti-slip area 14, the surfaces of the first anti-slip area 41 and the second anti-slip area 14 are respectively provided with raised transverse stripes, and the first anti-slip area 41 and the second anti-slip area 14 are respectively positioned at two opposite sides of the electrocardio-electrode buckle and are just two acting points of fingers when the user operates the electrocardio-electrode buckle. Thus, when the key 4 is pressed, the hidden trouble that the electrode buckle slips can not occur.

The foregoing is a more detailed description of the present application in connection with specific embodiments thereof, and it is not intended that the present application be limited to the specific embodiments thereof. It will be apparent to those skilled in the art from this disclosure that many more simple derivations or substitutions can be made without departing from the inventive concepts herein.
