Description

Improved structure of switch base

Technical Field

The invention relates to an improved structure of a switch base; in particular to a structure which makes the switch seat body adopt a thin plate structure to be made into a metal head part and a non-metal belly part to form an integral state.

Background

The switch or switch indicator used in motor, electronic and automatic control system to let operator know the working state of machine or power supply is prior art. The switch device comprises a base body or a body, and a switch internal component and a plurality of groups of terminal pins which are arranged in a cavity defined by the base body; and the terminal pins extend out of the cavity or the base body and are used for connecting an electrical lead or being plugged on the circuit board to form electrical connection. The lamp source is arranged in the cavity of the seat body, the electric property of the lamp source is connected with a group of positive and negative electrode pins of the pins, and the upper part of the cavity of the seat body is provided with a slightly transparent holding or pressing switch, so that an operator can obtain the effect of light emission or non-light emission of the lamp source through the holding or pressing switch to know the working state or the power supply switching state of the machine.

One problem associated with the manufacturing and structural design of such switchgear is that the existing switch housing or body is made entirely of a metallic material into a cylindrical body with an internal cavity, and a local area of the outer surface of the housing is turned and milled to form threads. After the internal cavity of the base body is combined with the internal components of the switch, the base body is forced to deform through pressurization operation, and the base body and the internal components of the switch are fixed to complete a switch device.

However, in the above case, the manufacturing and assembling of the seat body, the working procedure of the fixing and processing, etc. are troublesome and time-consuming, and the manufacturing cost is relatively increased.

Another problem related to the base of the switchgear in terms of structural design and operational application is that the base is made of a metal material selected from the following reasons: when the base of the switch device is mounted on the panel or the substrate for operation by a human operator, the base has sufficient structural rigidity to resist the external destructive force generated by the operation, for example, the reaction force applied by the substrate to the base causes the surface structure of the base to be worn, and the combination of the base and the substrate is loosened, which is not desirable.

The prior art discloses a switch base structure, which employs a technique of combining a metal head with a non-metal belly, so as to improve the above-mentioned situations of troublesome and time-consuming operations, and provide sufficient structural rigidity to resist the outside destructive force generated by the operation; for example, taiwan patent No. 103108052, "switch seat structure and manufacturing method thereof" provides a practical case.

The case includes a body for assembling the internal components of the switch, the body being a combination of a metal head and a non-metal web; the metal head is provided with a shoulder and a skirt part connected with the shoulder (and/or the skirt part is provided with a concave area and a secondary shoulder), and the shoulder and the skirt part jointly define a shaft hole; the shoulder part is in a convex shape towards the outside of the metal head part, and the skirt part extends towards the direction of the nonmetal belly part along the axial direction; and a matched forming module which is injected with the non-metal belly material and is combined on at least partial areas of the skirt part (and/or the concave area and the sub-shoulder part) so that the non-metal belly and the metal head part are combined into a whole structure.

One problem with the above-described embodiments in terms of structure and manufacture is that the metal spring portion must be formed into a cylindrical structure using a complete metal cylinder for turning and milling operations, and the shaft hole pattern for mounting the switch (button) assembly is formed by removing most of the material of the metal cylinder structure with a milling machine and/or a drilling machine.

The body structure and the manufacture of the case should be further improved to reduce the time and trouble of the manufacturing operation and to generate a large amount of metal waste, solve the problems of environmental pollution, cost influence and the like, and also promote the upgrading of the switch industry.

Typically, these references show the use and structural design of the body or body of the switchgear and its associated components. If the design is repeated to consider the seat body or the body and the related component structure, and the application situation mentioned above, it is different from the prior art, and the usage pattern can be changed, and it is different from the old method.

For example, compared with the prior art, the seat body or the body structure has sufficient structural hardness or strength to resist the outside destructive force (or external acting force) in the manufacturing process, so that the operations of milling, drilling and the like which must be performed in the old method can be improved or removed under the condition of reducing the abrasion of the surface structure of the seat body, and the situations of time and trouble in manufacturing operation, more metal waste, higher cost and the like can be reduced; or further make the base body (or the body) form a plurality of structural types (and/or dispose patterns or character parts for decoration and indication functions) under the effect of simple manufacture, and the personnel can select and use the body structure with different structural types according to the actual use occasion to increase the application range of the body structure. None of these issues is specifically taught or disclosed in the above referenced data.

Detailed Description

The technical solutions of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

As shown in fig. 1, 2 and 3, the improved switch base structure of the invention includes a switch base body 100, and the switch base body 100 is used for assembling the switch assembly 90 (or the connection terminal) to form a switch device or a switch assembly. In the preferred embodiment, the body 100 is a combination of a metal head 10 and a non-metal web 20 of thin plate structure, defining an axis χ.

In the following description, reference will be made to the upper, lower, outer, inner, etc. portions of the drawings as viewed from the direction indicated in the drawings.

In the illustrated embodiment, the metal head 10 is formed by direct pressing from a thin metal plate, and has a first wall 11 perpendicular (or inclined) to the axis x, and a second wall 12 connecting one end of the first wall 11 and parallel (or inclined) to the axis x, so as to define a shaft hole 30 at the position of the axis x. The first wall 11 and the second wall 12 of the metal head 10 (or the body 100) form an included angle therebetween, which is an acute angle, a right angle, or an obtuse angle.

In a possible embodiment, the selective connection of the other end of the first wall 11 forms a secondary wall 13; the auxiliary wall 13 is formed by bending the other end of the first wall 11 downward in the figure and extending in a direction parallel to the axis χ. And the first wall 11, the second wall 12 and the sub-wall 13 (in the direction shown in the figures) define an outer surface 11a, 12a, 13a and an inner surface 11b, 12b, 13b, respectively.

The dashed portions of fig. 1 and 2 depict that the first wall 11 of the metal head 10 allows for the arrangement or printing and embossing of a planar (or solid, hollow) pattern (text) portion 45 for decoration and/or indication.

Fig. 3 particularly shows that a space 35 is defined between the first wall 11 or the first wall inner surface 11b (and the sub-wall 13, the sub-wall inner surface 13b) and the second wall 12 or the second wall outer surface 12 a. And, make the non-metal belly 20 adopt plastics or its similar material to cooperate the shaping module, fill in the space 35, and link the whole areas of the first wall 11 (or first wall internal surface 11b) and the second wall 12 (or second wall external surface 12a) and/or the minor wall 13 (or minor wall internal surface 13b), make the non-metal belly 20 extend towards the lower side in the figure along the direction parallel to axis chi, and combine the integral form with the metal head 10, achieve the mutual reinforcement function of structure of the metal head 10 and non-metal belly 20; such as the situation depicted in fig. 4 (or fig. 19, 21).

The non-metallic web 20 is also shown as a cylindrical structure with threads 21 on the surface, and the non-metallic web 20 defines an internal space that fits into the axial bore 30 of the metallic head 10 for assembling the switch assembly 90. And, the shoulder 29 is provided in the inner space of the non-metal belly 20 to define the combination position of the metal head 10 and the non-metal belly 20 and to assist in positioning the metal head 10.

The dotted line of fig. 4 shows the combination of the body 100 and the substrate 40; therefore, when the body 100 and the base plate 40 are combined for operation by a user, the non-metal belly 20 cooperates with the sub-wall 13 of the metal head 10 to press the base plate 40, so as to form a stable combination effect, which is beneficial to obtain the effect of resisting the outside destructive force of the switch base body (or the body 100) and meets the condition of simple manufacture, and the situations of time consuming and troublesome processing and manufacturing operation, high material cost and the like are improved.

The dashed line in fig. 5 depicts the body 100 combined with the switch element 90 of another configuration.

As shown in fig. 6, a light source assembly 95 (e.g., an LED assembly) is installed in the inner space of the body 100 or the non-metallic belly 20; for example, the case is partially shown in dotted lines in the figure.

In a possible embodiment, the non-metal web 20 of the body 100 is provided with a limiting portion 22 having a hole structure (or a protrusion structure), and the light source assembly 95 (or the switch assembly 90) is assembled and fixed in the body 100 by forming the engaging portion 96 having the protrusion structure (or the hole structure) corresponding to the combination of the light source assembly 95 (or the switch assembly 90). And the shaft hole 30 of the metal head 10 is provided with a closing body 31; the closing body 31 is made of plastic material or the like and has a structure with a cross section of n-shaped body. Basically, the closing body 31 may be formed integrally with the non-metallic belly portion 20.

The figure depicts the enclosure 31 as including a base 32 in the upper region and a wall 33 vertically connecting the base 32; and, the wall portion 33 cooperates with the non-metal web portion 20 to press against the inner surface 12b and the outer surface 12a of the second wall 12 of the metal head portion, respectively, so as to form a pattern in which the non-metal web portion 20 covers the second wall 12, thereby obtaining a more stable fixing and combining effect.

In a preferred embodiment, the base 32 and/or the wall 33 of the enclosure 31 may be formed in a transparent manner, so that the light source assembly 95 (or the matching hollowed-out pattern portion 45) outputs light, thereby generating a more specific decoration and/or indication effect.

FIG. 7 is a modified embodiment of the present invention; the body 100 or the second wall 12 of the metal head is inclined to the axis x in the external direction (or the internal direction) of the body 100, so that the first wall 11 and the second wall 12 form an acute angle (or an obtuse angle). And, the second wall 12 extends and inclines towards the external direction of the body 100, so that the partial region 23 of the non-metal abdomen 20 is matched with the non-metal abdomen 20, and respectively pressed on the inner surface 12b and the outer surface 12a of the metal head second wall 12, forming a pattern that the non-metal abdomen 20 covers at least partial region of the second wall 12, and forming a stable fixing and combining effect.

And the second wall 12 extends and inclines towards the outer direction of the body 100, so that the partial area 23 of the non-metal abdomen 20 is matched with the non-metal abdomen 20 and respectively pressed on the inner surface 12b and the outer surface 12a of the metal head second wall 12, thereby forming the structure mode that the non-metal abdomen 20 covers the second wall 12.

As shown in fig. 10, the body 100 or the first wall 11 of the metal head is shown in a form extending obliquely to the axis χ direction and has an oblique section 11c, so that the other end of the first wall 11 (or the oblique section 11c) extends along the direction perpendicular to the axis χ to form the sub-wall 13, thereby allowing the whole sub-wall 13 to be (completely) pressed on the substrate 40.

FIG. 11 is a modified embodiment of FIG. 10; the body 100 or the second wall 12 of the metal head is inclined to the axis x in the external direction (or the internal direction) of the body 100, so that the first wall 11 and the second wall 12 form an acute angle (or an obtuse angle). And the second wall 12 extends and inclines towards the outer direction of the body 100, so that the partial area 23 of the non-metal abdomen 20 is matched with the non-metal abdomen 20 and respectively pressed on the inner surface 12b and the outer surface 12a of the metal head second wall 12, thereby forming the structure mode that the non-metal abdomen 20 covers the second wall 12.

As shown in fig. 12, the body 100 or the first wall 11 of the metal head is shown to be extended in a direction perpendicular to the axis χ, so that the other end of the first wall 11 is extended toward the outer direction of the body 100 to form a pattern in which the sub-wall 13 is inclined to the axis χ, and has a (inclined) head section 13 c; and the tail end of the sub-wall 13 (or the head section 13c) extends towards the external direction of the body 100 to form a connecting section 13d perpendicular to the axis x, and the connecting section 13d extends towards the external direction of the body 100 to form a tail section 13e inclined to the axis x, so that the metal head 10 (or the first wall 11 and the sub-wall 13) forms at least a two-step structure or a high-low step structure, and the metal head 10 has better elastic action to respond the acting force (or the reaction force applied to the body 100 by the substrate 40) generated by the operation of the switch device by a person.

In the embodiment adopted, the included angle between the first wall 11 and the secondary wall head section 13c is of the acute angle, right angle or obtuse angle type; the included angle between the auxiliary wall head section 13c and the connecting section 13d is acute angle, right angle or obtuse angle; and the included angle between the connecting section 13d and the tail section 13e is acute angle, right angle or obtuse angle.

FIG. 13 is a modified embodiment of FIG. 12; the body 100 or the second wall 12 of the metal head is inclined to the axis x in the direction of the exterior of the body 100, so that the first wall 11 and the second wall 12 form an acute angle therebetween. And the second wall 12 extends and inclines towards the outer direction of the body 100, so that the partial area 23 of the non-metal abdomen 20 is matched with the non-metal abdomen 20 and respectively pressed on the inner surface 12b and the outer surface 12a of the metal head second wall 12, thereby forming the structure mode that the non-metal abdomen 20 covers the second wall 12.

As shown in fig. 14, there is shown a structure in which the body 100 or the second wall 12 of the metal head 10 is provided with at least one combining part 14. In the embodiment adopted, the second wall 12 projects from the lower portion (in one piece) in a pattern of a plurality of combinations 14 along a direction parallel to the axis χ; the combined portion 14 includes a base region 14a located on the same plane as the second wall 12 (or the outer surface 12a of the second wall) and a sub-region 14b vertically bent from the base region 14a and protruding toward the outside of the body 100, so that the combined portion 14 forms an "L" shaped plate structure.

Fig. 15 illustrates a configuration in which the assembly portion 14 forms an "L" shaped plate structure, which is helpful for the non-metal abdomen portion 20 to combine with the metal head portion 10, and the structure of the assembly portion 14 is matched to make the metal head portion 10 not easily separate from the non-metal abdomen portion 20, so as to form a stable combination effect.

As shown in fig. 16, the structure of the body 100 or the second wall 12 of the metal head 10 is provided with at least one combining part 14, and the non-metal belly part 20 is provided with at least one caulking part 24.

As shown in fig. 18 and 19, the dotted line of fig. 18 shows the structural configuration of the combined switch element 90 (or terminal) of the body 100. In the embodiment shown, the metal head 10 has a larger area of the first wall 11 than the above-mentioned embodiment according to the practical use requirement, and the manufacturer can also arrange or print and press more patterns (characters) 45.

It should be noted that the axial hole 30 of the metal head 10 of the thin plate body allows a geometric profile to be directly pressed; for example, FIGS. 18 and 19 show the configuration of the (circular) shaft hole 30 with two sides connected to the (square) holes respectively. Thus, the shaft hole 30 also allows for a square, rectangular, triangular, polygonal, or other geometric profile configuration.

Fig. 20 and 21 are schematic structural views of a derivative embodiment of the present invention; the configuration of the (circular) axial hole 30 of the metal head 10 with the (long) holes connected to both sides thereof is shown. Furthermore, the non-metal belly 20 has a (circular or arc) main portion 25 and (long) wing portions 26 integrally connected to both sides of the main portion 25 according to practical requirements (and corresponding to the structure of the shaft hole 30 or assembling different types of switch components and light source components).

Typically, the improved structure of the switch housing has the following considerations and advantages over the prior art, while meeting the requirements of simplicity and ease of manufacture:

1. the body 100 and the related component structures have been redesigned to be different from the conventional ones, and to change the usage and operation modes thereof, unlike the conventional ones. For example, the body 100 includes a composite structure of the metal head 10 and the non-metal belly 20 in a thin plate structure, and the first wall 11, the second wall 12 and/or the sub-wall 13 of the metal head 10 together define the space 35, so that the non-metal belly 20 fills the space 35 and connects all the areas of the first wall 11, the second wall 12 and/or the sub-wall 13, which is more beneficial to the manufacturing process; such as the prior art, the seat body made of metal material or the whole metal column is troublesome in manufacturing/processing, time-consuming, material-consuming, and high in cost. In addition, the structural design can obviously reduce metal waste and solve the problems of environmental pollution and the like.

2. The structure of the body 100 or the second wall 12 of the metal head 11 inclined to the axis χ (and/or the shaft hole 30 provided with the closing body 31) facilitates the non-metal web 20 to wrap the outer surface 12a and the inner surface 12b of the second wall 12, so as to form a stable combination effect. The metal head 10 forms a thin plate structure, which not only has the function of easy press forming, but also forms a plurality of structural types, and the personnel can select and use the body 100 structure with different structural types (combine different types of switch components 90, light source components 95 or wiring terminals) according to the actual use occasion to increase the application range; the first wall 11 is also provided with a character part 45 which is easy to print patterns and can be used for decoration, indication and the like.

In summary, the above embodiments are merely preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
