Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of switches and relates to a mounting structure of a touch switch. BACKGROUND

[0002] The touch switch is a commonly used switch component in electrical equipment, which has the characteristics of sensitive action, high parameter precision and small size. The structure of the touch switch is disclosed in a touch switch and a manufacturing method thereof (application number: 201610339696.X), which comprises: an insulating layer, the lower surface of which is covered with a non-conductive substance; a conductive component, which is arranged on the insulating layer; a metal contact piece, which is arranged in a containing space and has a protruding portion in the middle; a pressing point for operation, which concentrates the pressing force of the external force on the touch switch on the middle part of the metal contact piece; and a protective layer, which is arranged on the insulating reinforcing layer and fixes the pressing point for operation and the metal contact piece in the containing space. The protective layer of the touch switch with the structure has limited buffering and shock-absorbing effect, and the touch switch is a device with relatively precise structure. When the touch switch is impacted, the touch switch is prone to damage, which affects the service life of the touch switch.

[0003] The mounting structure of the touch switch is used for mounting the touch switch, and the conventional structure is disclosed in a tripping and closing indication mechanism of an electronic molded case circuit breaker (application number: 201921928597.0), which is provided with a hook on each side of the mechanism frame corresponding to the second micro switch and the third micro switch, a clamping space is formed between the two hooks, the second micro switch and the third micro switch are clamped in the clamping space, and the clamping cooperation of the second micro switch, the third micro switch and the mechanism frame is formed. The second micro switch and the third micro switch respectively have a contact, then the moving contact is pressed to press the contact, and the first micro switch and the third micro switch are turned on or turned off. Although the moving contact is arranged to press the contact of the micro switch in the mechanism, the contact is prevented from being directly impacted, but there are some deficiencies: when a hard moving contact is used, the moving contact is difficult to form a buffering effect, and the impact force received by the moving contact will be directly transmitted to the contact, causing damage to the micro switch; and when a soft moving contact is used, although the moving contact can be deformed to form a good buffering effect when the moving contact is impacted, the soft moving contact will cause a delay when the moving contact is pressed to drive the contact to move, thus reducing the sensitivity and affecting the use performance of the touch switch. At present, in order to solve the problem, the conventional technical means is to install a spring on the touch switch to support the moving contact, for example, a power type micro switch (application number: 201310386666.0) is disclosed in the patent document, a spring is arranged between the button and the push rod, so that when the button is impacted, the spring can be deformed to achieve a good shock-absorbing effect, and the switch element is effectively protected. SUMMARY

[0004] The present application aims at the above-mentioned problems existing in the prior art, and provides a mounting structure of a touch switch.

[0005] The present application can be realized by the following technical scheme: a mounting structure of a touch switch, comprising a fixed support and an elastic support arranged on the fixed support, and the touch switch is arranged in the fixed support, characterized in that a buffer pad made of elastic material is sleeved on the contact of the touch switch, a strip-shaped guide protrusion is arranged on the inner wall of the fixed support adjacent to the buffer pad, the buffer pad can slide along the length direction of the guide protrusion to press the contact of the touch switch, the side of the touch switch away from the contact abuts against the elastic support, and the buffer pad abuts against the side of the guide protrusion under the elastic force of the elastic support.

[0006] In the mounting structure, the buffer pad is sleeved on the contact of the touch switch, and in use, the contact is moved by pressing the buffer pad to realize the connection of the touch switch. At this time, the buffer pad can have good buffering and damping effect, and when the buffer pad is impacted, the touch switch can be effectively prevented from being damaged, and the service life of the touch switch is prolonged. Since the touch switch is a device with relatively precise structure, after the buffer pad is arranged, it is important to ensure that the buffer pad accurately presses the contact to move. At this time, since the buffer pad is made of elastic material, under the elastic force of the elastic support, the buffer pad abuts against the side of the guide protrusion, and the buffer pad will be slightly deformed to form a "pressing groove" matched with the guide protrusion, so that the buffer pad is guided by the guide protrusion during movement, and the buffer pad can accurately press the contact of the touch switch each time, thereby ensuring the use performance of the touch switch.

[0007] In the installation structure of the touch switch, the fixed support comprises a top plate and two opposite side plates, the touch switch is located between the two side plates and connected with the two side plates respectively, the guide protrusion is located on the inner wall of the top plate, and the thickness of the guide protrusion protruding from the inner wall of the top plate gradually decreases from one end of the elastic support away from the other end. When the pressing cushion moves, the pressing cushion moves along the guide protrusion, and as the moving distance of the pressing cushion increases, the pressing cushion moves upward and gradually approaches the top plate, so that the deformation amount of the elastic support suddenly increases during the pressing process of the pressing cushion, which causes the pressing force to suddenly increase, thereby ensuring the pressing feeling, and also avoiding damage of the elastic support due to large deformation under pressure, and ensuring the stability and use performance of the touch switch installation. The touch switch is connected with the two side plates, so that the touch switch is installed more stably.

[0008] In the installation structure of the touch switch, the elastic support is a support strip in the shape of a plate and arranged along the height direction of the fixed support, and the upper end of the elastic support is integrally connected with the top plate. This structure not only facilitates manufacturing, but also ensures high structural strength of the elastic support, can provide a larger elastic force for the touch switch, and is not prone to breaking.

[0009] As another case, the elastic support can also be a metal spring, one end of the metal spring is fixed on the fixed support by a bolt, and the other end of the metal spring abuts against the side surface of the touch switch away from the contact.

[0010] In the installation structure of the touch switch, the touch switch comprises a conductive plate, the conductive plate is vertically arranged between the two side plates, the inner walls of the two side plates are respectively provided with a strip-shaped insertion slot arranged along the height direction of the fixed support, and the two side edges of the conductive plate close to the side plates are respectively inserted and arranged in the strip-shaped insertion slots on the inner walls of the two side plates. The conductive plate is a component of the touch switch for realizing electrical connection, which is a prior art, such as a touch switch and a manufacturing method thereof (application number: 201610339696.X), the wire component of the touch switch is the conductive plate described above. The installation structure inserts and fixes the conductive plate by providing strip-shaped insertion slots on the two side plates, so that the touch switch is easy to install. When the pressing cushion is pressed, the pressing force has a tendency to cause the touch switch to move backward as a whole, at this time, the strip-shaped insertion slots keep the position of the touch switch so that it only moves a small amount, thereby ensuring the quick connection of the touch switch, avoiding delay, improving the use performance of the touch switch, and also avoiding excessive deformation of the elastic support.

[0011] In the installation structure of the touch switch, the elastic support is gradually inclined from the upper end to the lower end towards the touch switch, and the lower end of the elastic support is provided with an anti-falling hook capable of limiting the downward falling of the conductive plate. The structure makes the inclined surface of the elastic support abutting against the touch switch face upwards, thus providing upward supporting force for the touch switch, making the installation of the touch switch stable, and also making the buffer pad well abut against the guide protrusion. The anti-falling hook plays an insurance role, and can avoid the falling of the touch switch.

[0012] In the installation structure of the touch switch, the buffer pad comprises a block-shaped body, and the end of the body facing the touch switch is provided with two turned-over edges respectively facing the two side plates. The turned-over edges abut against the front end surface of the touch switch from the side thereof, and the inner wall of the fixed support is further provided with two positioning plates. The turned-over edges abut against the two positioning plates from the side thereof away from the touch switch. The turned-over edges abut against the front end surface of the touch switch and the positioning plates, thus making the two turned-over edges capable of positioning the buffer pad, making the installation of the buffer pad stable, and making the side surface of the buffer pad capable of stably abutting against the sliding surface of the guide protrusion, thus making the guide protrusion capable of well guiding the movement of the buffer pad, and making the buffer pad capable of accurately pressing the contact each time, thus improving the use performance of the touch switch.

[0013] In the installation structure of the touch switch, the end surface of the body facing the touch switch is provided with a socket, and the contact is inserted into the socket. The design not only improves the positioning effect of the buffer pad, making the installation of the buffer pad stable, but also limits the relative position of the buffer pad and the contact, thus further ensuring the accurate pressing of the contact by the buffer pad.

[0014] In the installation structure of the touch switch, each side plate comprises an upper plate body and a lower plate body. The top edge of the upper plate body is connected with the top plate, and the bottom edge of the upper plate body is provided with a turned-over edge turned outwards. The top edge of the lower plate body is connected with the outer edge of the turned-over edge. The strip-shaped insertion slot is located on the inner wall of the upper plate body, and the lower end of the strip-shaped insertion slot is provided with a port for inserting the conductive plate. In the design, the distance between the lower plate bodies is large, making the bottom of the fixed support form a relatively open opening. The lower end of the strip-shaped insertion slot is provided with a port for inserting the conductive plate, thus facilitating the insertion of the touch switch into the strip-shaped insertion slot, and making the installation of the touch switch convenient.

[0015] In the installation structure of the touch switch, the fixing support is made of plastic material, and a metal support in the shape of a "door" is arranged between the two lower plate bodies of the two side plates. The metal support has two oppositely arranged side support plates and a connecting plate connecting the two side support plates, and the two side support plates are respectively attached to the inner walls of the two lower plate bodies. The fixing support is made of plastic material, which can be integrally formed with the guide protrusion and the strip-shaped insertion slot, and is convenient to manufacture. By arranging the metal support, the fixing support is reinforced to avoid deformation of the fixing support, ensure the installation precision of the touch switch and the cooperation precision of the buffer pad and the guide protrusion, so that the buffer pad can press the contact of the touch switch at a precise position each time, and the use performance of the touch switch is ensured.

[0016] In the installation structure of the touch switch, the buffer pad is made of rubber or silicone material. Preferably, the buffer pad is made of rubber material.

[0017] Compared with the prior art, the installation structure of the touch switch has the following advantages:

[0018] 1. In the installation structure, the buffer pad is sleeved on the contact of the touch switch. When in use, the contact is moved by pressing the buffer pad to realize the connection of the touch switch. At this time, the buffer pad can have a good buffering effect, and can effectively prevent the touch switch from being damaged when the buffer pad is impacted, thereby prolonging the service life of the touch switch.

[0019] 2. Since the buffer pad is made of elastic material, the buffer pad will be deformed slightly to form a "pressure groove" matched with the guide protrusion after the buffer pad is abutted against the side surface of the guide protrusion under the action of the elastic force of the elastic support, so that the buffer pad is guided by the guide protrusion during movement, and the buffer pad can press the contact of the touch switch at a precise position each time, thereby ensuring the use performance of the touch switch.

The touch switch 3 is disposed inside the fixed bracket 1. A buffer pad 4 made of elastic material is sleeved on the contact 31 of the touch switch 3. The buffer pad 4 is made of rubber material. The inner wall of the fixed bracket 1 adjacent to the buffer pad 4 is provided with a strip-shaped guide protrusion 5 arranged along the moving direction of the contact 31. The buffer pad 4 can slide along the length direction of the guide protrusion 5 to press the contact 31 of the touch switch 3. The side of the touch switch 3 facing away from the contact 31 abuts against the elastic support 2. Under the action of the elastic force of the elastic support 2, the buffer pad 4 abuts against the side of the guide protrusion 5.

[0032] The installation structure is characterized in that a buffer pad 4 is sleeved on the contact 31 of the touch switch 3, and in use, the contact 31 is moved by pressing the buffer pad 4 to realize the on of the touch switch 3.

Since the buffer pad 4 is made of an elastic material, under the action of the elastic force of the elastic support 2, after the buffer pad 4 abuts against the side surface of the guide protrusion 5, the buffer pad 4 will be slightly deformed to form a “pressing groove” matched with the guide protrusion 5, so that the buffer pad 4 is guided by the guide protrusion 5 during movement, and the buffer pad 4 can press the contact 31 of the touch switch 3 at a precise position each time, thereby ensuring the use performance of the touch switch 3.

[0033] Further, as shown in Figure 4 and Figure 5 , the fixed support 1 includes a top plate 1a and two oppositely arranged side plates 1b, the touch switch 3 is located between the two side plates 1b and connected with the two side plates 1b respectively, the guide protrusion 5 is located on the inner wall of the top plate 1a, and the thickness of the guide protrusion 5 protruding from the inner wall of the top plate 1a gradually decreases from one end away from the elastic support 2 to the other end.

This design not only improves the positioning effect of the cushion 4, so that the cushion 4 is stably installed, but also limits the relative position of the cushion 4 and the contact 31, and further ensures that the cushion 4 can precisely press the contact 31.

[0037] As shown in Figure 1 and Figure 3 Each side plate 1b comprises an upper plate body 1b1 and a lower plate body 1b2, the top edge of the upper plate body 1b1 is connected with the side edge of the top plate 1a, the bottom edge of the upper plate body 1b1 is provided with a turned-outwards flange 1b3, the top edge of the lower plate body 1b2 is connected with the outer edge of the flange 1b3, the strip-shaped insertion slot 6 is located on the inner wall of the upper plate body 1b1, and the lower end of the strip-shaped insertion slot 6 is provided with a port 61 for inserting the conductive plate 32.
