[0046] A relay is an electronic control device based on electromagnetic principle, which is used to automatically control the current and voltage in the circuit, and plays a role of automatic adjustment, safety protection, conversion circuit, etc. in the circuit.

[0047] With the wider application of relays, the relays not only have main circuits but also have auxiliary circuits. In the related art, when the magnetic field direction on the main circuit is parallel to the current direction of the auxiliary circuit during the working of the main circuit and the auxiliary circuit, according to Faraday's law, at this time, the magnetic flux is maximum, and the induction effect is strongest. In this way, the auxiliary circuit is easily affected by the electromagnetic interference of the main circuit, and the reliability of the relay is affected.

[0048] Based on the above consideration, in order to solve the problem that the auxiliary circuit is easily affected by the electromagnetic interference of the main circuit, a relay is designed, which comprises a shell, a main circuit switch and an auxiliary circuit switch, wherein the main circuit switch is arranged in the shell, the magnetic field direction in the main circuit switch is a first direction, the auxiliary circuit switch is arranged in the shell, the current direction in the auxiliary circuit switch is a second direction, and the second direction intersects the first direction.

[0049] In the technical scheme of the embodiment, since the current direction of the auxiliary circuit switch intersects the magnetic field direction of the main circuit switch, according to Faraday's law, at this time, the coupling energy of the magnetic field generated by the main circuit switch acting on the auxiliary circuit is small, that is, the electromagnetic induction effect of the change of the magnetic field generated by the main circuit switch on the auxiliary circuit is effectively inhibited, so that the auxiliary circuit can be effectively prevented from being affected by the electromagnetic interference of the main circuit, and the reliability of the relay is improved.

[0050] According to some embodiments of the present application, Figure 1 is a structural schematic diagram of a relay in the present application, Figure 2 is Figure 1 is a structural schematic diagram of the inside of the relay, Figure 3 is Figure 2 is an exploded view of the relay.

[0051] Referring to Figure 1 , the shell 11 in the embodiment comprises a first cover 111 and a second cover 112, wherein the first cover 111 and the second cover 112 form a closed cavity through clamping or bolt connection, and the main circuit switch 13 and the auxiliary circuit switch 14 are located in the corresponding closed cavities.

[0052] The main circuit switch 13 and the auxiliary circuit switch 14 in the embodiment both have the functions of turning on or off, and the main circuit switch 13 and the auxiliary circuit switch 14 are connected to the same power supply. Figure 3As shown, the magnetic field direction in the main circuit switch 13 is a first direction, and the current direction in the auxiliary circuit switch 14 is a second direction, wherein the second direction intersects the first direction, and the included angle between the first direction and the second direction can be 45°, 60°, 80°, etc., and the specific angle can be determined according to actual conditions, and the embodiments of the present application do not limit this.

[0053] In use, since the current direction of the auxiliary circuit switch 14 intersects the magnetic field direction of the main circuit switch 13, according to Faraday's law, at this time, the coupling energy of the magnetic field generated by the main circuit switch 13 acting on the auxiliary circuit is small, that is, the electromagnetic induction effect of the change of the magnetic field generated by the main circuit switch 13 on the auxiliary circuit will be effectively inhibited, thereby effectively avoiding the auxiliary circuit from being subjected to electromagnetic interference of the main circuit, and further improving the reliability of the relay 10.

[0054] According to some embodiments of the present application, the first direction is perpendicular to the second direction. In this way, according to Faraday's law, the magnetic field generated by the main circuit switch 13 cannot couple energy in the auxiliary circuit, and the electromagnetic induction effect of the change of the magnetic field generated by the main circuit switch 13 on the auxiliary circuit will be maximally inhibited, and the magnetic field cannot couple energy in the auxiliary circuit, thereby effectively avoiding the auxiliary circuit from being subjected to electromagnetic interference of the main circuit.

[0055] According to some embodiments of the present application, as shown in Figure 3 As shown, the relay further includes a push rod assembly 15, wherein the main circuit switch 13 includes a main static contact 132 and a main movable contact 135, and the auxiliary circuit switch 14 includes an auxiliary static contact 141 and an auxiliary movable contact 142; the push rod assembly 15, the main static contact 132 and the auxiliary static contact 141 are all arranged in the housing 11, and the main movable contact 135 and the auxiliary movable contact 142 are both arranged in the push rod assembly 15; the push rod assembly 15 is configured to simultaneously drive the main movable contact 135 and the auxiliary movable contact 142 to move, so that the main movable contact 135 is in contact with or disconnected from the main static contact 132, and the auxiliary movable contact 142 is in contact with or disconnected from the auxiliary static contact 141.

[0056] The push rod assembly 15 in the present embodiment can refer to the structure of driving the push rod to move after the coil of the relay is energized, which will not be described here.

[0057] Referring to Figure 3 As shown, the main static contact 132 and the auxiliary static contact 141 in the present embodiment can be clamped in the housing 11, or fixed in the housing 11 by a support seat, which is not limited here.

[0058] The active contact 135 and the auxiliary active contact 142 in the embodiment can be clamped on the push rod assembly 15, or the active contact 135 and the auxiliary active contact 142 are fixed on the push rod assembly 15 by bolts, and the specific determination can be made according to the actual situation, and the embodiment of the specification is not limited.

[0059] In use, as shown in Figure 3 , the active contact 135 and the auxiliary active contact 142 can be synchronously driven to move along the vertical direction by the push rod assembly 15. When the push rod assembly 15 drives the active contact 135 and the auxiliary active contact 142 to move upward along the vertical direction, the active contact 135 is in contact with the main static contact 132, and the auxiliary active contact 142 is in contact with the auxiliary static contact 141, and the main circuit switch 13 and the auxiliary circuit switch 14 are simultaneously turned on.

[0060] When the push rod assembly 15 drives the active contact 135 and the auxiliary active contact 142 to move downward along the vertical direction, the active contact 135 is separated from the main static contact 132, and the auxiliary active contact 142 is separated from the auxiliary static contact 141. At this time, the main circuit switch 13 and the auxiliary circuit switch 14 are simultaneously turned off. At this time, the auxiliary circuit switch 14 can be used to detect whether the main circuit switch 13 has contact adhesion or disconnection.

[0061] According to some embodiments of the present application, as shown in Figure 3 , the main circuit switch 13 further comprises a fastener 131 and an insulating sleeve 133. The fastener 131 is arranged in the housing 11, the insulating sleeve 133 is arranged on the part of the fastener 131 located in the housing 11, and the main static contact 132 is arranged on the insulating sleeve 133. The fastener 131 in the embodiment can be a bolt, and the insulating sleeve 133 can be a rubber sleeve, which is not limited here.

[0062] In use, the fastener 131 is fixed on the housing 11 by the cooperation of the bolt and the nut, then the insulating sleeve 133 is sleeved on the part of the fastener 131 located in the housing 11, and then the main static contact 132 is clamped on the insulating sleeve 133. In this way, the main static contact 132 can be conveniently fixed to the housing 11.

[0063] According to some embodiments of the present application, as shown in Figure 3 , the relay further comprises a protective cover 12, the protective cover 12 is arranged in the housing 11, the push rod assembly 15, the main static contact 132, the active contact 135 and the auxiliary active contact 142 are located inside the protective cover 12, the auxiliary static contact 141 is fixed to the protective cover 12, and the auxiliary static contact 141 is at least partially located outside the protective cover 12. At the same time, the fastener 131 is fixed to the protective cover 12, and the insulating sleeve 133 located inside the protective cover 12 is connected with the main static contact 132.

[0064] The protective cover 12 in the embodiment comprises a first insulating shell 121 and a second insulating shell 122, wherein the first insulating shell 121 and the second insulating shell 122 are buckled to form sealed cavities, and the push rod assembly 15, the main static contact 132, the main active contact 135 and the auxiliary active contact 142 are located in the corresponding sealed cavities. It is shown in the figure that the push rod assembly 15 is located in the first insulating shell 121, and the upper end of the push rod assembly 15 is connected with the main active contact 135 and the auxiliary active contact 142. Figure 3 It is shown in the figure that the push rod assembly 15 is located in the first insulating shell 121, and the upper end of the push rod assembly 15 is connected with the main active contact 135 and the auxiliary active contact 142.

[0065] The fastener 131 is connected with the second insulating shell 122 in the vertical direction through the cooperation of the nut and the gasket 134, one end of the fastener 131 is located in the second insulating shell 122, the other end of the fastener 131 is located outside the second insulating shell 122, and the insulating sleeve 133 located in the second insulating shell 122 is connected with the main static contact 132. The auxiliary static contact 141 is clamped on the second insulating shell 122, one end of the auxiliary static contact 141 is located in the second insulating shell 122, and the other end of the auxiliary static contact 141 is located outside the second insulating shell 122.

[0066] In this way, the auxiliary static contact 141 and the auxiliary active contact 142 are located inside the protective cover 12 when they are in contact or separated, at this time, under the isolation of the protective cover 12, the interference of the external electromagnetic field can be effectively shielded, and the purity of the auxiliary loop signal is improved.

[0067] According to some embodiments of the present application, as Figure 3 and in combination with Figure 4 It is shown in the figure that the auxiliary loop switch 14 further comprises an isolation seat 143, which is arranged on the push rod assembly 15, and the auxiliary active contact 142 and the main active contact 135 are located on the opposite sides of the isolation seat 143 along the moving direction of the push rod assembly 15.

[0068] The isolation seat 143 in the embodiment can be clamped or connected by bolts on the push rod assembly 15, and the isolation seat 143 is made of insulating material, such as rubber, silica gel, etc.

[0069] Since the auxiliary active contact 142 and the main active contact 135 are both made of metal material, when they are in contact with the corresponding auxiliary static contact 141 and main static contact 132, the phenomenon of electric conduction will occur, and by arranging the isolation seat 143 with insulation function between the auxiliary active contact 142 and the main active contact 135, the short circuit phenomenon between the auxiliary active contact 142 and the main active contact 135 can be avoided.

[0070] According to some embodiments of the present application, as Figure 3 and in combination with Figure 4 , Figure 5 It is shown in the figure that the push rod assembly 15 comprises a coil 151, a push rod 152, an elastic member 154 and an insulating seat 155.

[0071] The insulating seat 155 is arranged in the protective cover 12, the coil 151 is arranged on the insulating seat 155, the push rod 152 is arranged in the center hole on the coil 151, and the active contact piece 135 and the isolation seat 143 are both fixed on the end of the push rod 152 away from the coil 151.

[0072] One end of the elastic member 154 is fixed on the push rod 152, and the other end abuts against the side of the active contact piece 135 away from the isolation seat 143.

[0073] In the embodiment, the elastic member 154 can be deformed under external force and restored to the original state after the external force is removed. The elastic member 154 can be elastically compressed in the Y direction. The elastic member 154 can be made of metal or non-metal material, for example, a leaf spring, a coil spring, a gas spring, a rubber spring, etc. The specific material can be determined according to the actual situation, and the embodiment of the present application does not limit the same.

[0074] The through slot of the push rod 152 in the embodiment is usually made of soft magnetic material such as iron and silicon steel. Such material can be magnetized in a magnetic field to generate an attractive force with the magnetic field of the coil.

[0075] The insulating seat 155 in the embodiment can be bonded to the inner bottom surface of the first insulating shell 121. The coil 151 is wound on the insulating seat 155. The insulating seat 155 forms a center hole after winding. One end of the push rod 152 is located inside the center hole, and the other end is located outside the center hole. The active contact piece 135 and the isolation seat 143 are both clamped on the end of the push rod 152 outside the center hole. The elastic member 154 is sleeved on the push rod 152. The elastic member 154 is located below the active contact piece 135. One end of the elastic member 154 is fixed on the push rod 152, and the other end abuts against the bottom surface of the active contact piece 135.

[0076] When the coil 151 is energized, an electromagnetic effect is generated. At this time, the push rod 152 is magnetized to generate an attractive force with the magnetic field of the coil. The electromagnetic force overcomes the resistance of the elastic member 154. In this way, the push rod 152 drives the active contact piece 135 and the auxiliary active contact piece 142 to move, so as to realize the contact between the active contact piece 135 and the main static contact 132, and the contact between the auxiliary active contact piece 142 and the auxiliary static contact 141. After the coil 151 is disconnected, the elastic member 154 returns to the initial state. At this time, the electromagnetic force between the push rod 152 and the coil 151 disappears, the active contact piece 135 is separated from the main static contact 132, and the auxiliary active contact piece 142 is separated from the auxiliary static contact 141.

[0077] In the relay of the embodiment, the push rod can move after the coil is energized. Essentially, it is the result of the combined action of electromagnetic induction and mechanical transmission, which will not be described here.

[0078] It should be noted that the structure of the push rod assembly is only an example, and other structures can also be used in other alternative solutions, for example, the push rod assembly also includes a bolt, and the active contact piece and the auxiliary active contact piece are connected to the push rod through the bolt. The specific structure of the push rod is not specially limited in the present application, as long as the above structure can achieve the purpose of the present application.

[0079] According to some embodiments of the present application, as shown in Figure 3 or Figure 4 The push rod assembly 15 further includes a directional sleeve 153, which is arranged in the central hole and can move axially relative to the central hole, and one end of the push rod 152 towards the coil 151 is fixed to the directional sleeve 153.

[0080] The directional sleeve 153 in the present embodiment is in clearance fit with the central hole, and one end of the push rod 152 towards the coil 151 is clamped in the directional sleeve 153. Under the limitation of the directional sleeve 153, the push rod 152 can only move vertically relative to the central hole, avoiding the push rod 152 from deviating when moving relative to the central hole.

[0081] According to some embodiments of the present application, as shown in Figure 6 and in combination with Figure 3 , Figure 1 The relay further includes a base 17 and a first detection member (not indicated in the figure), wherein the first detection member is arranged on the base 17, and the base 17 is provided with a first insertion hole 171; The coil 151 is provided with a wire head 1511, which is at least partially located outside the shell 11, and under the condition that the wire head 1511 is inserted into the first insertion hole 171, the first detection member is configured to detect the coil 151.

[0082] The first detection member in the present embodiment can be a multimeter, an insulation resistance tester, an oscilloscope, etc., which can be determined according to actual conditions, and the present specification does not limit this.

[0083] In use, after the wire head 1511 is inserted into the first insertion hole 171, the first detection member is inserted into the first insertion hole 171, at which time the first detection member is in conduction with the wire head 1511, and the resistance value of the coil 151 is detected by the first detection member. For example, when the resistance value deviates from the nominal value within ±10%, it is determined that the coil 151 is normal, otherwise it is determined that the coil 151 is abnormal.

[0084] According to some embodiments of the present application, as shown in Figure 6 and in combination with Figure 3 , Figure 1As shown, the relay further includes a plug-in plate 16, on which a plug connector 161 is provided. The plug connector 161 is at least partially located outside the housing 11, and the plug-in plate 16 is electrically connected to the auxiliary static contact 141; wherein, a second socket 172 is provided on the base 17, and when the plug connector 161 is inserted into the second socket 172, the first detection member is configured to detect the auxiliary static contact 141.

[0085] The first detection member in this embodiment can be referred to the above description and will not be described again here.

[0086] In this embodiment, after the plug connector 161 is inserted into the second jack 172, the first detection member is correspondingly inserted into the second jack 172. At this time, the first detection member is connected to the plug connector 161, and the rated current is connected to the contact circuit. The voltage drop across the auxiliary static contact 141 is measured using the voltage range of the multimeter. If the voltage drop is within the preset value range, for example, the voltage drop is within 0-50mV, the auxiliary static contact 141 is determined to be normal; otherwise, the auxiliary static contact 141 is determined to be abnormal.

[0087] The present application also provides a production line comprising a relay as in any one of the embodiments of the present application.

[0088] The production line in this embodiment can be a battery production line, a material conveying production line, etc., which is not limited here.

[0089] Because the current direction of the auxiliary circuit switch 14 in this relay intersects the magnetic field direction of the main circuit switch 13, according to Faraday's law, the coupling energy of the magnetic field generated by the main circuit switch 13 on the auxiliary circuit is relatively small. In other words, the electromagnetic induction effect of the magnetic field change generated by the main circuit switch 13 on the auxiliary circuit is effectively suppressed, thereby effectively preventing the auxiliary circuit from being affected by electromagnetic interference from the main circuit, thereby improving the reliability of the relay 10. In this way, when the relay is used in a corresponding production line, the reliability of the production line can also be improved.
