Description

Technical Field

[0001] This application relates to the technical field of relays, and specifically to a relay with a self-locking function. Background Art

[0002] A relay is an automatic control device whose output will change in a jump when the input quantity (electricity, magnetism, sound, light, heat) reaches a certain value. Specifically, when the input quantity (such as voltage, current, temperature, etc.) reaches the specified value, the relay will make the controlled output circuit conduct or disconnect. Relays are widely used in devices such as power protection, automation, motion, remote control, measurement, and communication, and have the advantages of fast action, stable operation, long service life, and small size. The working principle of a relay mainly uses the principle of electromagnetic induction to control the opening and closing of the circuit. A relay usually consists of a coil, an iron core, contacts, etc. When the coil of the relay is energized, a magnetic field will be generated around the iron core, and this magnetic field will attract the contacts, causing the contacts to close, thus making the circuit energized. When the coil is de-energized, the magnetic field disappears, and the contacts return to their original state under the action of the spring, and the circuit is disconnected.

[0003] The terminals of a relay refer to the remote laying ends that connect the circuit on the relay. They are generally arranged on the base or fixed plate of the relay for users to use when wiring. The relay terminals play a key role in the connection between the relay and the external circuit, and undertake the important task of leading out the signal output by the relay for the next-level circuit to use.

[0004] The terminals can be connected to external devices by plugging. Because the material of the terminals is long-strip metal, when the terminals are subjected to external extrusion force, the terminals will deform, resulting in looseness during the subsequent plugging process with the devices. Utility Model Content

[0005] The purpose of this application is to provide a relay with a self-locking function to solve the problem that when the terminals are subjected to external extrusion force, the terminals will deform, resulting in looseness during the subsequent plugging process with the devices as mentioned in the above background art.

[0006] To achieve the above purpose, this application provides the following technical solution: A relay with a self-locking function, comprising: a relay main body and a protection and storage mechanism. The protection and storage mechanism is arranged outside the relay main body. The protection and storage mechanism includes a first rack integrally formed around the outer wall of the relay main body, a protection shell sleeved outside the relay main body, and a second rack integrally formed around the inner wall of the protection shell, and the first rack meshes with the second rack.

[0007] By adopting the above technical solution, the protection of the terminals can be achieved by moving.

[0008] Preferably, the protection and storage mechanism further includes a first terminal fixedly arranged at the bottom of the relay body.

[0009] By adopting the above technical solution, the subsequent connection work with external devices can be carried out.

[0010] Preferably, the protection and storage mechanism further includes a hole opened on the first terminal, and the cross-sectional shape of the hole is rectangular.

[0011] By adopting the above technical solution, the internal structure can be provided for movement.

[0012] Preferably, the protection and storage mechanism further includes a fastener arranged inside the hole. The fastener can slide and displace inside the hole, and the fastener is composed of a screw and a nut.

[0013] By adopting the above technical solution, a quick fixing effect can be achieved by twisting.

[0014] Preferably, the protection and storage mechanism further includes a second terminal attached to the outer wall of the first terminal, and the outer wall of the second terminal is welded to the screw of the fastener.

[0015] By adopting the above technical solution, rotational storage can be carried out by rotating.

[0016] Preferably, the protection and storage mechanism further has a positioning block integrally formed at the bottom of the relay body, and the cross-sectional shape of the positioning block is "L".

[0017] By adopting the above technical solution, the structure on one side can be positioned by snap-fitting.

[0018] Preferably, the protection and storage mechanism further includes a convex block welded to the second terminal, and the shape of the convex block is a cubic block with rounded corners on all four sides.

[0019] By adopting the above technical solution, contact with the structure on one side can be made, so as to quickly achieve snap-fitting.

[0020] In summary, the present application has the following beneficial effects: By providing a protection and storage mechanism, when the protective shell moves and stores outside the relay body, it is convenient for external devices to be quickly plugged into the terminal. When the plugging work is completed, by moving the protective shell to the connection part, the connection part can be protected. And through the meshing of the first rack and the second rack, the effect of positioning the protective shell at any specified position is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0027] The following will be further described in detail in conjunction with the attached Figures 1-4 for the embodiments of the present application.

[0028] Embodiment 1

[0029] Please refer to Figures 1-4 , this embodiment provides a technical solution: a relay with a self-locking function, including: a relay main body 1 and a protection and storage mechanism 2;

[0030] Relay main body 1, when the relay main body 1 works, the coil is energized to generate a magnetic field, and the magnetic field attracts the magnet to move, thereby driving the contact to close or open. In this process, the circuit where the control circuit coil is located and the circuit where the working circuit contact is located are isolated, achieving the purpose of controlling a larger current with a smaller current. The above is the prior art and will not be elaborated below. The protection and storage mechanism 2 is arranged outside the relay main body 1, and the protection and storage mechanism 2 can provide effective protection during the connection process between the relay main body 1 and external devices.

[0031] The protective storage mechanism 2 includes a No. 1 rack 201 integrally formed around the outer wall of the relay body 1, and the No. 1 rack 201 can be meshed with the structure on the outside to achieve a rapid fixing effect. A protective shell 202 is sleeved on the outside of the relay body 1, and the cross-section of the protective shell 202 is a "mouth" shape. The opening inside the protective shell 202 is adapted to the size of the relay body 1, thereby providing the protective shell 202 with smooth movement outside the relay body 1. A No. 2 rack 203 is integrally formed around the inner wall of the protective shell 202. The material of the No. 2 rack 203 and the No. 1 rack 201 are both plastic materials, and through the characteristics of the material, they have a certain degree of deformation function. The No. 1 rack 201 is meshed with the No. 2 rack 203. During the meshing process of the No. 2 rack 203 and the No. 1 rack 201, the protective shell 202 can be provided with smooth movement, and when the protective shell 202 moves to the specified position, it can be quickly positioned.

[0032] When the relay body 1 needs to be connected to an external device, the protective shell 202 is manually moved so that the protective shell 202 no longer continues to protect the bottom of the relay body 1, thereby facilitating the subsequent plug-in of external devices. When the protective shell 202 moves to a specified position, the engagement of the No. 1 rack 201 and the No. 2 rack 203 can provide the protective shell 202 with rapid positioning at the specified position.

[0033] Example 2

[0034] See also Figures 1-4 , this embodiment provides a technical solution: a relay with a self-locking function, comprising: a No. 1 terminal 204, a hole 205, a fastener 206, a No. 2 terminal 207, a positioning block 208 and a protrusion 209;

[0035] A terminal 204 is fixedly arranged at the bottom of the relay body 1, and the terminal 204 can provide connection with external equipment. A hole 205 is opened on the terminal 204, and the cross-section of the hole 205 is rectangular. The hole 205 can provide the internal structure to move in a specified direction. A fastener 206 is arranged inside the hole 205. The fastener 206 can synchronously drive the externally connected structure to move and rotate synchronously during the movement inside the hole 205. The fastener 206 is composed of a screw and a nut. The screw of the fastener 206 is arranged inside the hole 205, so as to provide the structure connected to the outside of the fastener 206 with stable movement. The terminal 207 is attached to the outer wall of the terminal 204. The terminal 207 can play the function of plug-in connection with external equipment, and the screw of the fastener 206 is welded on the outer wall of the terminal 207. The terminal 207 can be rotated inside the hole 205 through the fastener 206, thereby playing an effective storage role.

[0036] A positioning block 208 is integrally formed at the bottom of the relay body 1, and the cross-section of the positioning block 208 is in an "L" shape. The positioning block 208 can provide structural stability of the outside by limiting the contact with the structure on the outside. A protrusion 209 is welded on the second terminal 207, and the protrusion 209 is in the shape of a cube with rounded corners on all sides. When the protrusion 209 is rotated and located inside the positioning block 208, it can provide structural stability of the external connection.

[0037] When stored, terminal No. 1 204 and terminal No. 2 207 are distributed at an angle of 90°. When it is necessary to connect terminal No. 207 to external equipment, the fastener 206 is loosened so that terminal No. 2 207 can be rotated in the hole 205 of terminal No. 1 204 through the fastener 206. When terminal No. 1 204 and terminal No. 2 207 are in a close and parallel state, the fastener 206 is tightened to provide a certain degree of fixation between terminal No. 1 204 and terminal No. 2 207. During the rotation of terminal No. 2 207, the protrusion 209 on the outside of terminal No. 2 207 will be engaged with the inside of the positioning block 208, thereby maintaining the stability of terminal No. 2 207 during the plug-in operation and avoiding the phenomenon of angle deviation.

[0038] The implementation principle of a relay with a self-locking function of the present application is:

[0039] First, when the relay body 1 needs to be connected to an external device, the protective shell 202 is manually moved so that the protective shell 202 no longer continues to protect the bottom of the relay body 1, thereby facilitating the subsequent plug-in of external devices. When the protective shell 202 moves to the specified position, the engagement of the No. 1 rack 201 and the No. 2 rack 203 can provide the protective shell 202 with rapid positioning at the specified position.

[0040] Secondly, when stored, terminal No. 1 204 and terminal No. 2 207 are distributed at a 90° angle. When it is necessary to connect with external equipment through terminal No. 2 207, the fastener 206 is loosened so that terminal No. 2 207 can be rotated in the hole 205 of terminal No. 1 204 through the fastener 206. When terminal No. 1 204 and terminal No. 2 207 are in a close and parallel state, the fastener 206 is tightened to provide a certain degree of fixation between terminal No. 1 204 and terminal No. 2 207.

[0041] Finally, during the rotation of the second terminal 207, the bump 209 on the outer side of the second terminal 207 will be engaged into the inside of the positioning block 208, so as to maintain the stability during the insertion operation of the second terminal 207 and avoid the phenomenon of angular deviation. After the insertion operation is completed, the protective case 202 is moved back to its original position, thereby protecting the insertion connection.

[0042] For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present application is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed in the present application.
