Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to an emergency stop switch that is easy to install. Background Technology

[0002] An emergency stop switch, also known as an emergency stop button, is widely used in various mechanical equipment and production lines to immediately cut off the power supply to the equipment in an emergency, thereby protecting the safety of personnel and equipment. At the same time, an emergency stop button usually has two basic functions: first, it cuts off the power supply to the equipment through a contact, so that the equipment stops operating immediately; second, it locks after the button is pressed, and can only be used again after being manually reset.

[0003] In addition, emergency stop buttons typically have two pins: one for connecting to the power supply and the other for connecting to the device's control circuit. When the button is pressed, the contacts close, cutting off the power supply and control circuit, and stopping the device from operating.

[0004] Currently, pin mounting typically involves a through-slot in the housing and a pin with an end-positioning stop and a protrusion. Pin mounting usually requires a fixture; the external end of the pin is forced through the through-slot by the fixture's downward pressure, simultaneously inserting the protrusion into the slot. Once the protrusion extends from the other side of the slot, the pin mounting is complete. After mounting, the pin is reliably installed thanks to the engagement of the end-positioning stop and the protrusion. However, this mounting method often encounters issues during the installation process. The process is cumbersome, and to achieve the installation of the normally open contact on the pin, a right-angle bend is usually formed between the contact installation position and the pin. This can cause "bulges" during the tooling pressing process, resulting in inconsistencies with the design drawings and potentially failing to meet customer requirements. Alternatively, if the protrusion is not installed properly during installation, i.e., it does not extend from the other end of the through slot, the normally open contact inside the housing will not be properly limited, allowing it to move up and down within the housing, thus affecting stability. Summary of the Invention

[0005] In view of the above shortcomings, this utility model provides an emergency stop switch that allows the pin portion to be installed in accordance with the drawing, thereby meeting customer needs and making the pin portion easy to install.

[0006] To achieve the above objectives, this utility model employs an easy-to-install emergency stop switch, comprising a housing, normally closed contacts and normally open contacts distributed within the housing, and an emergency stop head covering the housing. Each normally closed and normally open contact includes a moving contact mechanism with a moving contact point and a pin with a stationary contact point. A locking area is formed on the side of the pin. The housing includes a mounting base with an embedded groove for lateral pin insertion. A locking portion adapted to the locking area is formed within the embedded groove. The pin is laterally inserted into the embedded groove and limited by the engagement of the locking area and the locking portion, thus limiting the pin's installation on the mounting base of the emergency stop switch.

[0007] The present invention is further configured such that the edge of the mounting base also includes a locking groove, and a locking block is adapted to the locking groove. The pin of the mounting base is embedded in the inner groove, and the locking block is embedded in the locking groove to form an auxiliary limit for the pin in the mounting base.

[0008] The present invention is further configured such that the engaging area is formed on one side of the pin.

[0009] The present invention is further configured such that the engaging area is formed on both sides of the pin.

[0010] The present invention is further configured such that the engaging area is one or more grooves opened on the side of the pin, and the engaging part is a protrusion formed on the mounting base that matches the number of grooves.

[0011] The present invention is further configured such that the engaging area is one or more protrusions opened on the side of the pin, and the engaging part is a groove formed on the mounting base that matches the number of grooves.

[0012] The beneficial effects of this utility model are as follows: By incorporating a typical emergency stop switch including a housing, normally closed and normally open contacts distributed within the housing, and an emergency stop head covering the housing, and by including both normally closed and normally open contacts as moving contact mechanisms with moving contacts and pins with stationary contacts, and by including a mounting base in the housing portion, the pins are mounted on the housing, i.e., on the mounting base, using a mounting method where engaging areas are respectively formed on the sides of the pins, and corresponding recesses for lateral insertion of the pins are formed on the mounting base at the pin mounting positions, while engaging portions for engaging the engaging areas on the pins are formed within the recesses, thereby enabling the emergency stop switch to operate smoothly when the pins are engaged. When the pin needs to be installed with the mounting base, it can be inserted laterally into the recessed slot on the mounting base. After insertion, the engagement area and engagement part cooperate to reliably install and limit the pin on the housing. Compared with the existing method, its installation convenience is greatly improved. Moreover, the installation process can be done manually, and it will not affect the reliability of use due to improper installation, or cause "bubbling" during the vertical insertion and tooling pressing process of the existing method, which may result in inconsistencies with the design drawings and failure to meet customer requirements.

[0020] like Figure 1-7As shown, a specific embodiment of this utility model is an easy-to-install emergency stop switch, including a housing 2, normally closed contacts a and normally open contacts b distributed on the housing 2, and an emergency stop head covering the housing 2. The normally closed contacts a and normally open contacts b each include a moving contact mechanism c with a moving contact 5 and a pin 3 with a stationary contact 4. A locking area 31 is formed on the side of the pin 3. The housing 2 includes a mounting base 21, and an inner groove 211 for inserting the pin 3 laterally is provided on the mounting base 211. A locking part 213 adapted to the locking area 31 is formed in the inner groove 211. The pin 3 is laterally inserted into the inner groove 211 and limited by the cooperation between the locking area 31 and the locking part 213, thus forming the installation limit of the pin 3 on the mounting base 21 on the emergency stop switch.

[0021] By incorporating a typical emergency stop switch, including a housing 2, normally closed contacts a and normally open contacts b distributed on the housing 2, and an emergency stop head covering the housing 2, and by including a moving contact mechanism c with a moving contact 5 for both normally closed contacts a and normally open contacts b, and a pin 3 with a stationary contact 4, and by including a mounting base 21 for the housing 2, the pin 3 is mounted on the housing 2, i.e., on the mounting base 21, in the following mounting method: engaging areas 31 are respectively provided on the side of the pin 3, and an inner groove 211 for lateral insertion of the pin 3 is provided on the mounting base 21 at the position corresponding to the mounting of the pin 3, and an engaging part 213 for engaging the engaging areas 31 on the pin 3 is formed in the inner groove 211, thereby... This design allows pin 3 to be installed on mounting base 21 by side-embedding it into the recess 211 on mounting base 21. After embedding, the engagement area 31 and engagement part 213 cooperate to reliably install and limit pin 3 on housing 2. Compared with existing designs, this design greatly improves the ease of installation. The installation process can be done manually, and it avoids the problems of improper installation affecting reliability, or the "bubbling" that may occur during the longitudinal insertion and tooling pressing process of existing designs, which could lead to discrepancies with design drawings and failure to meet customer requirements.

[0022] like Figure 2-3 As shown, the edge of the mounting base 21 also includes a slot 212, on which a slot block 6 is adapted. The pin 3 of the mounting base 21 is embedded in the slot 211. The insertion of the slot block 6 into the slot 212 forms an auxiliary limiting design for the pin 3 in the mounting base 21, which can further ensure that the pin 3 is installed into the mounting base 21. This can achieve reliable limiting and prevent accidental dislodgement.

[0023] like Figure 3 , 5As shown in Figure 7, the engagement area 31 on the pin 3 can be formed on one side of the pin 3 or on both sides. Since the pin 3 is limited by the mounting base 21, the pin 3 only needs to be inserted laterally into the recess 211 of the mounting base 21, and after the engagement area 31 cooperates with the engagement part 213, the installation and limitation of the pin 3 can be completed. By involving engagement areas 31 on both sides of the pin 3, since there are multiple pins 3 used in the emergency stop switch, some need to be inserted from the left and some need to be inserted from the right, the universality of the pin 3 design can be guaranteed. There will be no need for different styles of pins 3 when used for different positions. That is, if it is used for insertion on the left, the pin 3 with engagement area 31 on the left needs to be used, and if it is used for insertion on the right, the pin 3 with engagement area 31 on the right needs to be used. This greatly improves the convenience of use of this utility model and also greatly reduces the impact of inventory pressure.

[0024] like Figure 3 , 5 As shown in Figure 7, the engaging area 31 is one or more grooves opened on the side of the pin 3, and the engaging part 213 is a protrusion formed on the mounting base 21 that matches the number of grooves; the design scheme of engaging area 31 being one or more protrusions opened on the side of the pin 3 and engaging part 213 being a groove formed on the mounting base 21 that matches the number of grooves; allows the engaging area 31 or engaging part 213 to be designed on the mounting base 21 or the pin 3 without being limited to protrusions and grooves, and only sitting on the pin 3 or the mounting base 21, thus greatly improving the limitation of the pin 3 when it is engaged and limited on the mounting base 21.
