Description

Technical Field

[0001] This application belongs to the technical field of push-button switches, and particularly relates to a side-connected push-button switch. Background Art

[0002] In a push-button switch configured with an indicator light, the indicator light assembly is integrally connected to the pressing end of the push-button switch and is in contact with the conductive contact of the push-button switch through two conductive springs to achieve stable electrical connection. The conductive contacts are configured as a contact for connecting the live wire and a contact for connecting the neutral wire according to the difference in the connected power supply terminals, and connect the two power supply terminals of the indicator light assembly; therefore, the state position accuracy and reliability of the conductive contacts will directly affect the functional stability of the indicator light assembly. Usually, in order to facilitate installation on various carrier devices such as power strips, the shape of the push-button switch is generally rectangular. Limited by the mold opening area, the lead-out position of the conductive contacts is usually set on the side in the width direction of the housing of the push-button switch to ensure that there is enough area on the width side of the housing to open a fixing structure to accommodate and fix the conductive contacts.

[0003] However, the operating conditions of the push-button switch when it is carried and used are diverse, and the shapes of the installation spaces are also very different. For example, for some electrical devices such as power strips that have multiple push-button switches and share the neutral wire, it is necessary to configure an extension copper sheet or wire for each neutral wire contact to lead out the neutral wire conductive contact in the length direction of the housing. To a certain extent, it can shorten the connecting copper sheet, reduce the overall cost; it can also reduce the complexity of the overall structure and the space occupation, and improve the electrical safety. Limited by the mold opening area, it is difficult to open the fixing structure on the side in the length direction of the housing, making it difficult to ensure the fixing stability and assembly accuracy of the neutral wire conductive contact, and affecting the functional stability and safety of the switch.

[0045] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0046] In addition, this application may repeat reference numbers and / or reference letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials, but those of ordinary skill in the art will recognize the application of other processes and / or the use of other materials.

[0047] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0048] In some push button switches, various electrical components such as indicator lights are usually configured. One power supply end of the electrical component will be connected to the conductive structure of the push button switch, and the other power supply end needs to be connected to the neutral wire contact to connect to the common neutral wire of terminal equipment such as a power strip. However, due to the small specifications of the shell side in the length direction of the push button shell, it is difficult to open the mold to process the fixed structure, so the neutral wire contact is usually led out from the side in the width direction of the shell. However, in some assembly conditions, such as multiple push button switches are arranged at intervals, and the common neutral wire is usually set on one side of the length direction of the shell. For this reason, additional wires, extended copper sheets and other connectors need to be set to connect between the neutral wire contact and the common neutral wire, which increases the overall structural complexity, reduces the efficiency of assembly operations, and increases costs. Even if the neutral wire contact is led out from the length direction, there will be problems with unreliable fixed structure and poor position and posture accuracy.

[0049] To this end, an embodiment of the present application provides a key switch, which aims to improve the convenience, precision and reliability of the use and assembly of the key switch to a certain extent.

[0050] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 In some embodiments, the side-connected push button switch can be based on the push button switch to plan the fixed structure and assembly method of the neutral wire contact, so that the neutral wire contact can be led out from the length direction of the shell, and the stability of the position and posture of the neutral wire contact can be ensured, and the assembly accuracy and reliability can be improved.

[0051] Specifically, the side connection safety switch may include: a housing 1 composed of a buckled base 11 and an upper cover 12, a moving contact piece 2, a static contact piece 3, a neutral wire contact piece 4, a ratchet button mechanism 5, an indicator light 6, and a pressure bearing seat 7.

[0052] The moving contact piece 2 and the static contact piece 3 are respectively fixed on the base 11. The ratchet button mechanism 5 is disposed in a ratchet seat 13 on the upper cover 12 and abuts against the free end 21 of the moving contact piece 2. Thus, by pressing the free end 21 of the moving contact piece 2, the free end 21 is driven to approach and connect with the static contact piece 3, or the connection between the free end 21 and the static contact piece 3 is disconnected. And through the self-locking ability of the ratchet button mechanism 5, the connection state between the free end 21 and the static contact piece 3 is maintained, or the disconnected state is maintained.

[0053] Generally, the moving contact piece 2 and the static contact piece 3 extend along the width direction W of the base 11. In contrast, the direction orthogonal to the width direction is the length direction L, and the direction orthogonal to both the length direction L and the width direction W is the thickness direction H.

[0054] A limiting through groove 121 is formed on the end face 126 of the upper cover 12 close to the base 11, and the limiting through groove 121 penetrates through the length direction side wall 127 of the upper cover 12 along the length direction of the upper cover 12. A bayonet 45 is formed on the side edge of the neutral wire contact piece 4, and the bayonet 45 is engaged with the side wall 121a of the limiting through groove 121, thereby locking the neutral wire contact piece 4 in the limiting through groove 121, and being able to limit the movement of the neutral wire contact piece 4 in the length direction L and the width direction W of the upper cover 12, and maintaining the stability of the position and posture.

[0055] A supporting boss 111 is provided on the base 11 and is used for being embedded into the limiting through groove 121, so as to press the neutral wire contact piece 4 tightly in the limiting through groove 121 in the thickness direction H of the upper cover 12, thereby limiting the position and posture of the neutral wire contact piece 4 in the thickness direction H of the upper cover 12.

[0056] That is to say, it is possible to achieve the high-precision and stable fixation of the neutral wire contact piece 4 only through the buckling of the upper cover 12 and the base 11, and there is no need to provide a fixing structure on the length side of the upper cover 12 and the base 11.

[0057] During assembly, the neutral wire contact piece 4 can be first correspondingly snapped into the limiting through groove 121, and then the upper cover 12 is correspondingly buckled with the base 11.

[0058] The indicating lamp 6 is used to track and indicate the conduction state of the moving contact piece 3 and the static contact piece 4. It has two power supply terminals, one of which is connected to one of the moving contact piece 3 and the static contact piece 4, and the other power supply terminal is connected to the neutral line contact piece 4.

[0059] The pressure-bearing seat 7 is connected to the pressing end of the ratchet key mechanism 5 and is used to bear the pressing operation. And the pressure-bearing seat 7 can also be used as a carrier for accommodating the indicating lamp 6, and can directly display the indication signal.

[0060] In some embodiments, in order to reduce the difficulty of processing and forming, the support boss 111 may include a first support vertical plate 111a and a second support vertical plate 111b. The first support vertical plate 111a and the second support vertical plate 111b are erected on the surface of the base 11 facing the upper cover 12, that is, erected along the thickness direction H of the base 11, and the first support vertical plate 111a and the second support vertical plate 111b are vertically connected to form a T-shaped bracket, so that the support boss 11 has a support area in the width direction W and the length direction L, and can stably press the neutral line contact piece 4 in a large range.

[0061] Wherein, the side end face of the first support vertical plate 111a close to the upper cover 12 is set in a convex shape, which is adapted to the shape of the limit through groove 121, so as to be able to stably embed and press the neutral line contact piece 4.

[0062] It should be noted that the first support vertical plate 111a can be used as a side shell side wall of the base 11, that is, a side wall in the length direction of the upper cover 12, so as to simplify the forming difficulty of the support boss 111 to a certain extent and reduce the structural complexity.

[0063] In some embodiments, the length direction of the neutral line contact piece 4 can be set along the length direction L of the base 11, and the side edge of the second support vertical plate 111b in contact with the neutral line contact piece 4 can be set along the length direction of the neutral line contact piece 4, so as to stably press the neutral line contact piece 4 in a large area.

[0064] Correspondingly, the side edge of the first support vertical plate 111a in contact with the neutral line contact piece 4 is set along the width direction of the neutral line contact piece 4, so as to stably press the neutral line contact piece 4.

[0065] In order to avoid interfering with the surface structure of the base 11, the second support vertical plate 111b can be in the shape of a triangular plate-like, with the hypotenuse facing the base 11, so as to reduce the interference risk between the second support vertical plate 111b and the structure on the base 11.

[0066] In some embodiments, considering that the indicating lamp 6 moves following the pressure-bearing seat 7, in order to improve the electrical connection reliability between the indicating lamp 6, the moving contact piece 2 and the neutral wire contact piece 4, an elastic conductive member can be used to connect the indicating lamp 6 to the moving contact piece 2 and the neutral wire contact piece 4, so as to adapt to the moving mode of the indicating lamp 6.

[0067] Specifically, the two power supply terminals of the indicating lamp 6 are respectively connected to the moving contact piece 2 and the neutral wire contact piece 4 through a first conductive spring 61 and a second conductive spring 62, and the telescopic deformation directions of the first conductive spring 61 and the second conductive spring 62 can be set along the moving direction of the indicating lamp 6 and the pressure-bearing seat 7.

[0068] Generally speaking, the first conductive spring 61 and the second conductive spring 61 can adopt barrel springs, and their stable telescopic deformation is mainly in their axial directions. Therefore, the axial directions of the first conductive spring 61 and the second conductive spring 61 can be set along the moving direction of the indicating lamp 6 and the pressure-bearing seat 7.

[0069] During installation, the two ends of the first conductive spring 61 can be respectively abutted against a power supply terminal of the indicating lamp 6 and the moving contact piece 2, and the two ends of the second conductive spring 62 can be respectively abutted against the other power supply terminal of the indicating lamp 6 and the neutral wire contact piece 4.

[0070] In some embodiments, considering that the Roton spring is weak in radial strength and is prone to deformation, resulting in unsatisfactory attitude stability of the first conductive spring 61 and the second conductive spring 62 and affecting the reliability of the conductive structure.

[0071] A first through hole 122 and a second through hole 123 penetrating the upper cover 12 can be opened on the upper cover 12. The first conductive spring 61 can be inserted into the first through hole 122, and the second conductive spring 62 can be inserted into the second through hole 123, so as to limit the radial deformation amplitude of the first conductive spring 61 and the second conductive spring 62 to a certain extent.

[0072] Generally speaking, the hole ends of the first through hole 122 and the second through hole 123 can be axially extended into a cylindrical structure to increase the limiting area for the first conductive spring 61 and the second conductive spring 62 and strengthen the attitude maintaining performance.

[0073] In some embodiments, in order to strengthen the electrical connection stability between the second conductive spring 62 and the neutral line contact 4, a limiting cylinder 124 can be directly formed on the inner surface of the upper cover 12, and the limiting cylinder 124 is in matching communication with the second through hole 123. The first end of the neutral line contact 4 can be inserted into the cavity of the limiting cylinder 124, and the abutting part between the second conductive spring 62 and the neutral line contact 4 can be stably limited within the limiting cylinder 124, so as to maintain the matching posture, limit external interference, and ensure the reliability of the electrical connection.

[0074] In some embodiments, for the convenience of insertion and installation, an insertion through groove 124a can be opened on the axial end surface of the limiting cylinder 124, and the insertion through groove 124a penetrates through the cylinder wall of the limiting cylinder 124, thus forming a semi-open groove body, reducing the difficulty of insertion and facilitating the insertion of the neutral line contact 4.

[0075] Generally, the bottom surface 124a1 of the insertion through groove 124a can be substantially flush with the bottom surface 121b of the limiting through groove 121, so as to ensure the smoothness of insertion, and reduce the risk of abutting interference.

[0076] In some embodiments, the neutral line contact 4 can be connected to external conductive parts, such as a socket, a wire, etc., by means of plug-in connection or riveting connection.

[0077] Specifically, a plug pin 41 can be provided on the neutral line contact 4 to achieve plug-in assembly with conductive parts such as plug-in terminals provided on the basis of external products, thereby improving the efficiency of the assembly operation to a certain extent.

[0078] Generally, the side connection push-button switch is fixed in the product along the height direction. For the convenience of installation, the plug pin 41 can also be arranged along the height direction of the housing 1, that is, the plug pin 41 faces the base 11, so that when the housing 1 is installed, the plug pin 41 can be inserted synchronously, with convenient operation; it can also reduce the space occupation.

[0079] In some embodiments, the external connection of the neutral line contact 4 needs to be connected by a wire. For this purpose, a wire clamping hook 42 can be provided on the neutral line contact 4. The wire 43 can be arranged in the wire clamping hook 42, and then the wire clamping hook 42 is flattened to clamp the wire 43. The operation is convenient and the connection state is stable.

[0080] Generally, the wire pressing hook 42 can be arranged on the side of the neutral line contact 4 close to the base 1, so as to hide the hook body, and after assembly, the risk of hooking external structures can be reduced.

[0081] In some embodiments, in order to improve the stability of the wire clamping, a wire clamping boss 421 and a wire clamping groove 422 can be provided on two opposite wire clamping surfaces of the wire clamping hook 42, so that when the wire is clamped tightly, some segments of the wire 43 are compressed and deformed closer together.

[0082] Correspondingly, the positions of the wire clamping boss 421 and the wire clamping groove 422 are opposite to each other and their specifications are adapted.

[0083] In some embodiments, in order to improve the convenience of assembly operation and the stability of the structure, a guide column 125 can be provided on the upper cover 12, and an ear hole 71 can be opened on the pressure seat 7. The guide column 125 is inserted into the ear hole 71, and the axial direction of the guide column 125 is set along the moving direction of the pressure seat 7, so as to limit the lateral displacement of the pressure seat 7, ensure the directional stability of the pressing operation, and reduce the lateral push on the first conductive spring 61 and the second conductive spring 62, thereby ensuring the stability of their axial deformation posture and the reliability of the electrical connection.

[0084] Generally speaking, the indicator light 6 can be configured in the form of an integrated circuit board to ensure stable electrical connection and convenient installation.

[0085] In some embodiments, the ratchet button mechanism 5 may include a large ratchet gear 51, a small ratchet gear 52 and a ratchet spring 53, which are nested in sequence. The large ratchet gear 51 can be adapted to be embedded in the ratchet seat 13, and the ratchet spring 53 abuts against the free end 21 of the moving contact piece 2.

[0086] See also Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 and Figure 16 In some embodiments, the neutral line contact piece 4 can also be led out from the width direction W of the housing 1, and the positions of the supporting boss 111 and the limiting slot can also be adaptively adjusted.

[0087] In some embodiments, a positioning boss 44 may be further provided in the area of the neutral contact piece 4 that contacts the second conductive spring 62 to limit the displacement of the end of the second conductive spring 62 .

[0088] The embodiments of the present application have at least the following beneficial effects:

[0089] The side connection push-button switch provided by the embodiment of the present application includes a buckled base and upper cover, a moving contact piece, a static contact piece, a neutral wire contact piece, a ratchet button mechanism, an indicator light, and a pressure-bearing seat. The moving contact piece and the static contact piece are detachably arranged on the base. The ratchet button mechanism is arranged on the upper cover and abuts against the moving contact piece to realize pressing to conduct or disconnect the connection between the moving contact piece and the static contact piece, thereby realizing the function of the push-button switch. The indicator light is arranged in the pressure-bearing seat. The pressure-bearing seat is connected to the ratchet button mechanism. The power supply ends of the indicator light are respectively connected to the moving contact piece and the neutral wire contact piece, so as to track and indicate the on-off state of the push-button switch through the indicator light. On the other hand, a limiting through groove penetrating the side wall of the upper cover is opened on the side surface in the length direction of the upper cover to accommodate the neutral wire contact piece, and a bayonet is opened on the neutral wire contact piece. The bayonet is engaged with the groove body of the limiting through groove, so as to fix the neutral wire contact piece in the length direction and the width direction. A supporting convex platform adapted to the limiting through groove is also arranged on the base. In the state where the base and the upper cover are buckled, the supporting convex platform is embedded in the limiting through groove, and the supporting convex platform presses the neutral wire contact piece tightly in the limiting through groove, so as to fix the neutral wire contact piece in the thickness direction. That is to say, only by using the buckled upper cover and base can the three-dimensional positioning of the neutral wire contact piece be realized, and high-precision positioning and attitude maintenance can also be realized, thereby ensuring the assembly accuracy and fixing reliability, and there is no need to open a complex structure on the side surface in the length direction of the housing, greatly reducing the mold opening difficulty on the side surface of the housing and facilitating processing.
