Description

Technical Field

[0001] The present application generally relates to the field of relays, and more particularly, to a double relay. Background Art

[0002] In the field of high-voltage DC relay technology, a common method for connecting low-voltage coils to relays is to provide a coil power supply connection port in the middle or bottom of the relay housing. This port typically features tinned pins as male terminals, with a pin protection structure on the housing. The tinned pins are integrally injection-molded with the coil bobbin. The coil pins are typically stamped parts, while the pin protection structure on the housing is integrally injection-molded. The coil pins and the pin protection structure work together to form the male terminals of the connector.

[0003] The cost of stamping and electroplating the pins is high, and the high dimensional accuracy requirements of the pin protection structure on the housing increase the cost, resulting in a high overall cost.

[0004] The male end of the connector composed of the coil pin and the pin protection structure can only be fixed at a specific position of the relay, which lacks the flexibility of installation and use compared to the lead wire form with a connector. Utility Model Content

[0005] One of the purposes of the present application is to provide a double relay that can overcome at least one of the drawbacks of the prior art.

[0006] One object of the present application is to provide a double relay that can simplify the coil output structure and reduce the output cost.

[0007] Another object of the present application is to provide a double relay that can conveniently select the outer diameter and length of the connecting cable and the type of connector according to different application scenarios.

[0008] Another object of the present application is to provide a double relay that can reduce interference of cables in a housing, save space, and optimize cable layout.

[0009] Another object of the present application is to provide a double relay that can facilitate the connection between the relay and the external circuit.

[0010] According to a first aspect of the present application, there is provided a double relay comprising:

[0011] a first coil and a second coil arranged side by side;

[0012] a cable guiding mechanism configured to guide a first connecting cable of the first coil and a second connecting cable of the second coil;

[0013] The cable guiding mechanism includes a first guide member and a second guide member, the first guide member is configured to guide a first connecting cable of the first coil, and the second guide member is configured to guide a second connecting cable of the second coil, wherein the first guide member and the second guide member are arranged side by side adjacent to each other between the first coil and the second coil.

[0014] The first and second connecting cables are respectively restricted and retained by the first and second guiding members, so that the first and second connecting cables do not move around in the housing, thereby preventing the connecting cables from interfering with other components in the housing.

[0015] In some embodiments of the double relay, the cable guide mechanism is configured to guide a first connecting cable for the first coil and a second connecting cable for the second coil into a parallel arrangement, so that the cables exit in parallel from the housing of the double relay. The ability to exit the housing in parallel further standardizes the design layout of the connecting cables and consolidates the cables exiting from both relay units.

[0016] In some embodiments of a double relay, the double relay includes a first coil bobbin and a second coil bobbin. The first coil bobbin is configured to receive the first coil, and the second coil bobbin is configured to receive the second coil. The first guide member is disposed on the first coil bobbin, and the second guide member is disposed on the second coil bobbin. This fully utilizes the existing structure of the relay, does not occupy additional space within the housing, and also ensures structural stability of the first and second guide members.

[0017] In some embodiments of a double relay, the double relay includes a first insulating plate and a second insulating plate, with the first guide member disposed on the first insulating plate and the second guide member disposed on the second insulating plate. This fully utilizes the existing structure of the relay, does not occupy additional space within the housing, and also ensures structural stability of the first and second guide members.

[0018] In some embodiments of the double relay, the first guide member is in the form of a guide groove, and / or the second guide member is in the form of a guide groove.

[0019] In some embodiments of the double relay, the first guide member and the second guide member are centrally disposed between the first coil and the second coil. This central design can balance the uniform distribution of the connecting cables, fully utilize the space inside the housing, and simplify the structure.

[0020] In some embodiments of the double relay, the first coil has a first primary pin and a first secondary pin, and the second coil has a second primary pin and a second secondary pin, wherein the first guide member is located between the first primary pin and the first secondary pin, and the second guide member is located between the second primary pin and the second secondary pin.

[0021] In some embodiments of the double relay, the first connecting cable of the first coil includes a first primary connecting cable and a first secondary connecting cable, and the second connecting cable of the second coil includes a second primary connecting cable and a second secondary connecting cable, wherein the first primary connecting cable is guided by the first guide member and the first secondary connecting cable bypasses the first guide member, and / or the second primary connecting cable is guided by the second guide member and the second secondary connecting cable bypasses the second guide member. When the first secondary pin and the second secondary pin are close to the outlet port, the number of guiding members can be reduced, further simplifying the structure and saving space.

[0022] In some embodiments of the double relay, the cable guiding mechanism includes an outlet port provided with a wire groove for a first connecting cable of the first coil and a second connecting cable of the second coil.

[0023] The restraint and guidance of the cable trough further limits the movement of the connecting cable, improving its stability. With the help of the guiding member and the cable trough, the connecting cable can be selected according to the actual coil power. The outer diameter of the connecting cable can be adapted by adjusting the size of the guiding member and the cable trough.

[0024] In some embodiments of the double relay, the outlet port is provided with at least four spaced-apart cable ducts arranged side by side, so that the first connecting cable of the first coil and the second connecting cable of the second coil are guided in parallel through the at least four cable ducts, so as to exit the housing of the double relay in parallel. Providing multiple rows of cable ducts can provide more stable restraint for the connecting cables.

[0025] In some embodiments of a double relay, the outlet port is provided with two or more rows of cable ducts for a first connecting cable for the first coil and a second connecting cable for the second coil, with a cavity formed between the two or more rows of cable ducts. Glue can be poured into the cavity to enhance the stability and tightness of the connecting cables.

[0026] In some embodiments of the double relay, the double relay includes an upper housing and a lower housing, the upper housing and the lower housing cooperate to form a housing of the double relay, wherein the outlet port is formed at an interface between the upper housing and the lower housing.

[0027] In some embodiments of the double relay, the outlet port includes a first half and a second half, the first half is formed on the upper shell, and the second half is formed on the lower shell, so that when the upper shell and the lower shell are matched, the first half and the second half match each other to form the wire groove.

[0028] In some embodiments of the double relay, the double relay includes a fool-proof mark, which is arranged near the outlet port and corresponds to the corresponding wire trough to facilitate identification of the connecting cables received by each wire trough.

[0029] In some embodiments of a double relay, the double relay includes a common connector. A first connecting cable for the first coil and a second connecting cable for the second coil are connected to the common connector through a cable guide mechanism. The common connector extends to the exterior of the double relay housing via the first connecting cable for the first coil and the second connecting cable for the second coil. This connection method differs from the prior art, which requires additional connecting wires to establish an electrical connection between the relay and the external circuit, and is more convenient to operate.

[0030] The coil bottom outlet structure with a novel design according to the present application can be applied to integrated relays. The bottom outlet structure is orderly and concise, so that the cable can be pressed into the wire slot with appropriate pressure, without being taut or loose, ensuring smooth internal tightening and high mass production processability.

[0046] In the field of high-voltage DC relay technology, a common method for connecting low-voltage coils to relays is to provide a coil power supply connection port in the middle or bottom of the relay housing. This port typically features tinned pins as male terminals, with a pin protection structure on the housing. The tinned pins are integrally injection-molded with the coil bobbin. The coil pins are typically stamped parts, while the pin protection structure on the housing is integrally injection-molded. The coil pins and the pin protection structure work together to form the male terminals of the connector.

[0047] The above-mentioned conventional lead-out method has numerous drawbacks, such as the high cost of stamping and plating the pins, and the high dimensional precision requirements of the pin protection structure on the housing, which increases the overall cost. The male end of the connector, consisting of the coil pins and the pin protection structure, can only be fixed in a specific position on the relay, which lacks the installation and flexibility of lead-out methods with connectors.

[0048] To this end, the present application provides a new type of wiring design, which completely changes the above-mentioned wiring method, can reduce the cost of the relay, and make the installation of the relay quite flexible. At the same time, the outer diameter, length and connector model of the connecting cable can be selected according to different situations.

[0049] Figure 1Schematic perspective view of a double relay 1 according to some embodiments of the present application is shown. The relay of the present application mainly relates to a double relay, that is, a relay having two relay units, which are arranged side by side. Specifically, as Figure 1 As shown, the double relay 1 has a housing 10 for accommodating the various components of the double relay 1. The housing 10 includes an upper housing 102 and a lower housing 104, which mate together to form the housing 10. In the illustrated embodiment, the upper housing 102 can be relatively tall, while the lower housing 104 can be relatively short, forming a substantially plate-like structure. As a result, the connection interface between the upper housing 102 and the lower housing 104 is generally located at the bottom of the housing 10. Structures for mating, such as snap fasteners, can be formed around the perimeters of the upper housing 102 and the lower housing 104, enabling the upper housing 102 to be connected to the lower housing 104 through, for example, a snap fit.

[0050] The double relay 1 may include a first relay unit 12 and a second relay unit 14, which may be arranged side by side in a housing 10. Figure 1 As shown, they can be electrically connected to each other in parallel or in series. Each relay unit can include a corresponding coil, each coil is fixed to a coil frame, and the coil frame can be fixed to, for example, the lower housing, thereby holding the relay unit in the housing of the double relay.

[0051] According to some embodiments of the present application, a double relay 1 may include: a first coil 20 and a second coil 22 arranged side by side; and a cable guide mechanism 30 configured to guide a first connecting cable 21 of the first coil 20 and a second connecting cable 23 of the second coil 22. The cable guide mechanism 30 may include a first guide member 32 configured to guide the first connecting cable 21 of the first coil 20, and a second guide member 34 configured to guide the second connecting cable 23 of the second coil 22. The first guide member 32 and the second guide member 34 are arranged side by side, adjacent to each other, between the first coil 20 and the second coil 22.

[0052] like Figure 2 and Figure 3 As shown, it shows a partial exploded perspective view and a schematic diagram of the double relay 1, wherein Figure 3For clarity, the housing 10 is removed. According to some embodiments, the first relay unit 12 may include a first coil 20, and the second relay unit 14 may include a second coil 22, such that the first coil 20 and the second coil 22 are arranged side by side. The first coil 20 may be electrically connected to an external circuit (e.g., a circuit board) via a first connecting cable 21, and the second coil 22 may be electrically connected to the external circuit via a second connecting cable 23, such that power is supplied to the first coil 20 and the second coil 22 by the external circuit.

[0053] like Figures 4 to 8 , which shows a schematic diagram of some components of the double relay 1. The double relay 1 may further include a cable guide mechanism 30, which is configured to guide the first connecting cable 21 of the first coil 20 and the second connecting cable 23 of the second coil 22, so that the first connecting cable 21 and the second connecting cable 23 can be extended in an orderly manner along a regular guide route in the housing 10. Specifically, the cable guide mechanism 30 may include a first guide member 32 and a second guide member 34, the first guide member 32 is configured to guide the first connecting cable 21 of the first coil 20, and the second guide member 34 is configured to guide the second connecting cable 23 of the second coil 22, as shown in FIG. Figure 4 and Figure 5 The first connecting cable 21 and the second connecting cable 23 are respectively restricted and retained by the first guide member 32 and the second guide member 34 so that the first connecting cable 21 and the second connecting cable 23 do not move around in the housing 10, thereby preventing the connecting cables from interfering with other components in the housing 10.

[0054] According to some embodiments of the present application, the first guide member 32 and the second guide member 34 may be arranged adjacent to each other side by side between the first coil 20 and the second coil 22. Specifically, when the first coil 20 and the second coil 22 are arranged side by side, the first guide member 32 and the second guide member 34 may be disposed at a position intermediate the first coil 20 and the second coil 22. In one embodiment, the first guide member 32 and the second guide member 34 may be disposed between the first coil 20 and the second coil 22 near the bottom, i.e., approximately at the bottom of the housing 100.

[0055] By providing a cable guide mechanism 30, the extension of the connecting cable of the coil can be guided, the positioning and installation of the connecting cable can be facilitated, the movement of the connecting cable can be constrained and restricted, and the connecting cable can be prevented from interfering with other components in the housing 10. By arranging the first guide member 32 and the second guide member 34 between the first coil 20 and the second coil 22, the extension length of the connecting cable can be reduced, the arrangement of the connecting cable in the housing 10 can be optimized, the insulation distance between the low-voltage coil outlet and the yoke iron part can be ensured, the outlet structure is separated and stable, the risk of local breakdown of the coil is reduced, and safety is improved. The adoption of such a solution will make the connection method between the coil pin and the connecting cable not limited to soldering, but also phosphor copper welding, cold pressure welding, ultrasonic spot welding, resistance welding, etc., which significantly improves the flexibility and adaptability of processing.

[0056] According to some embodiments of the present application, the cable guiding mechanism 30 is configured to guide the first connecting cable 21 of the first coil 20 and the second connecting cable 23 of the second coil 22 into a parallel arrangement so as to be parallelly led out from the housing 10 of the double relay 1 .

[0057] As described above, the first guide member 32 and the second guide member 34 can be arranged side by side adjacent to each other, whereby the first guide member 32 and the second guide member 34 can guide and constrain the connecting cables to extend side by side (i.e., be arranged in parallel). After being guided by the first guide member 32 and the second guide member 34, the connecting cables extending side by side can be routed out of the housing 10 in the form of a parallel arrangement.

[0058] The connecting cables can be routed out of the housing in parallel, further standardizing the design layout of the connecting cables and integrating the outgoing cables of the two relay units together.

[0059] According to some embodiments of the present application, the double relay 1 may include a first coil frame 24 and a second coil frame 25, the first coil frame 24 is configured to receive the first coil 20, the second coil frame 25 is configured to receive the second coil 22, the first guide member 32 may be set on the first coil frame 24, and the second guide member 34 may be set on the second coil frame 25.

[0060] like Figures 2 to 5 As shown, the coil of each relay unit corresponds to a coil bobbin. The first coil 20 can be fixedly mounted on the first coil bobbin 24, and the second coil 22 can be fixedly mounted on the second coil bobbin 25. The first coil bobbin 24 and the second coil bobbin 25 can be fixed to the lower housing 104, thereby fixing the first relay unit 12 and the second relay unit 14 to the housing 10.

[0061] In some embodiments, the first guide member 32 may be attached to the first bobbin 24 or formed from a portion of the first bobbin 24, and the second guide member 34 may be attached to the second bobbin 25 or formed from a portion of the second bobbin 25. For example, during molding, a portion of the first bobbin 24 may be directly molded into the first guide member 32, and a portion of the second bobbin 25 may be directly molded into the second guide member 34. When the first bobbin 24 and the second bobbin 25 are fixed to the lower housing 104, the molded first guide member 32 and the second guide member 34 may be arranged side by side adjacent to each other.

[0062] By arranging the first guide member 32 and the second guide member 34 on the first coil frame 24 and the second coil frame 25 respectively, the existing structure of the relay can be fully utilized without occupying additional space in the housing 10, while also achieving structural stability of the first guide member 32 and the second guide member 34.

[0063] According to some embodiments of the present application, the double relay 1 may include a first insulating plate 242 and a second insulating plate 252 , the first guide member 32 may be disposed on the first insulating plate 242 , and the second guide member 34 may be disposed on the second insulating plate 252 .

[0064] In some embodiments, in order to avoid interference between the two relay units and provide a certain arc extinguishing effect, an insulating plate may be provided. Figure 5 As shown, a first insulating plate 242 may be formed corresponding to the first coil former 24, and a second insulating plate 252 may be formed corresponding to the second coil former 25. In one embodiment, the first insulating plate 242 may be disposed on the first coil former 24 or formed as a part of the first coil former 24, and the second insulating plate 252 may be disposed on the second coil former 25 or formed as a part of the second coil former 25.

[0065] In some embodiments, the first guide member 32 may be attached to the first insulating plate 242 or formed from a portion of the first insulating plate 242, and the second guide member 34 may be attached to the second insulating plate 252 or formed from a portion of the second insulating plate 252. For example, during molding, a portion of the first insulating plate 242 may be directly molded into the first guide member 32, and a portion of the second insulating plate 252 may be directly molded into the second guide member 34. The first insulating plate 242 and the second insulating plate 252 may be arranged such that the molded first guide member 32 and the molded second guide member 34 are adjacent to each other and arranged side by side.

[0066] By arranging the first guide member 32 and the second guide member 34 on the first insulating plate 242 and the second insulating plate 252 respectively, the existing structure of the relay can be fully utilized without occupying additional space in the housing 10, while also achieving structural stability of the first guide member 32 and the second guide member 34.

[0067] According to some embodiments of the present application, the first guide member 32 may be in the form of a guide groove, and / or the second guide member 34 may be in the form of a guide groove.

[0068] like Figure 5 As shown, the first guide member 32 and the second guide member 34 are both in the form of an elongated groove in which the connecting cable can be clamped to guide and constrain the connecting cable.

[0069] According to some embodiments of the present application, the first guide member 32 and the second guide member 34 may be centrally disposed between the first coil 20 and the second coil 22 .

[0070] like Figure 5 As shown, the first guide member 32 and the second guide member 34 are shown to be approximately located in the middle of the first coil bobbin 24 and the second coil bobbin 25, that is, approximately located in the middle between the first coil 20 and the second coil 22, close to the bottom of the first coil 20 and the second coil 22. This centered design can balance the even distribution of the connecting cables, facilitate full utilization of the space inside the housing 10, and simplify the structure.

[0071] According to some embodiments of the present application, the first coil 20 may have a first primary pin 202 and a first secondary pin 204, and the second coil 22 may have a second primary pin 222 and a second secondary pin 224. The first guide member 32 may be located between the first primary pin 202 and the first secondary pin 204, and the second guide member 34 may be located between the second primary pin 222 and the second secondary pin 224.

[0072] like Figure 4 and Figure 5As shown, each coil can have two pins for electrical connection to an external circuit via a connecting cable. In some embodiments, the first primary pin 202 and the first secondary pin 204 are spaced apart from each other, and the line connecting them can be approximately perpendicular to the line connecting the first coil former 24 and the second coil former 25, that is, approximately perpendicular to the line connecting the first coil 20 and the second coil 22. Similarly, the second primary pin 222 and the second secondary pin 224 are spaced apart from each other, and the line connecting them can be approximately perpendicular to the line connecting the first coil former 24 and the second coil former 25, that is, approximately perpendicular to the line connecting the first coil 20 and the second coil 22. In this way, the first guide member 32 can be positioned between the first coil 20 and the second coil 22, or between the first primary pin 202 and the first secondary pin 204, and the second guide member 34 can be positioned between the first coil 20 and the second coil 22, or between the second primary pin 222 and the second secondary pin 224.

[0073] Providing the guide member between the pins is beneficial for guiding the connecting cables, reducing unnecessary winding and saving space in the housing.

[0074] According to some embodiments of the present application, the first connecting cable 21 of the first coil 20 may include a first primary connecting cable 212 and a first secondary connecting cable 214, and the second connecting cable 23 of the second coil 22 may include a second primary connecting cable 232 and a second secondary connecting cable 234, wherein the first primary connecting cable 212 can be guided by the first guide member 32 and the first secondary connecting cable 214 can bypass the first guide member 32, and / or the second primary connecting cable 232 can be guided by the second guide member 34 and the second secondary connecting cable 234 can bypass the second guide member 34.

[0075] like Figure 4 and Figure 6 As shown, the first primary connection cable 212 can be connected to the first primary pin 202, the first secondary connection cable 214 can be connected to the first secondary pin 204, the second primary connection cable 232 can be connected to the second primary pin 222, and the second secondary connection cable 234 can be connected to the second secondary pin 224. In the illustrated embodiment, because the first secondary pin 204 and the second secondary pin 224 are close to the outlet port 40 (described below), it is optional not to guide the first secondary connection cable 214 and the second secondary connection cable 234 before they are output, so that the first secondary connection cable 214 and the second secondary connection cable 234 can be directly output from the housing 10. However, those skilled in the art will appreciate that in other embodiments not shown, guide members can also be provided to guide the first secondary connection cable 214 and the second secondary connection cable 234 accordingly.

[0076] When the first secondary pin 204 and the second secondary pin 224 are close to the outlet port 40 , the number of guide components can be reduced, the structure can be further simplified, and space can be saved.

[0077] According to some embodiments of the present application, the cable guiding mechanism 30 may include a cable outlet port 40 , and the cable outlet port 40 may be provided with a cable groove 42 for the first connecting cable 21 of the first coil 20 and the second connecting cable 23 of the second coil 22 .

[0078] like Figure 2 、 Figure 7 and Figure 8 As shown, the first connecting cable 21 of the first coil 20 and the second connecting cable 23 of the second coil 22 can be further guided and constrained through the outlet port 40 before exiting the housing 10, for example, by being caught in a wire groove 42. The wire groove 42 can be provided or formed on the housing 10, for example, when the housing 10 is molded, the wire groove 42 can be directly molded on the housing 10. Multiple wire grooves 42 can be arranged side by side and spaced apart to form a roughly comb-like shape. The size and shape of the wire groove 42 can be determined according to the connecting cables that need to be guided and constrained.

[0079] The restraint and guidance of the wire groove 42 can further limit the movement of the connecting cable and improve its stability. Under the action of the above-mentioned guide member and wire groove 42, the connecting cable can be selected according to the actual coil power. The outer diameter of the connecting cable can be adapted by adjusting the size of the guide member and the wire groove.

[0080] According to some embodiments of the present application, the outlet port 40 can be provided with at least four wire grooves 42 arranged side by side and spaced apart, so that the first connecting cable 21 of the first coil 20 and the second connecting cable 23 of the second coil 22 are guided into a parallel arrangement via at least four wire grooves 42 so as to be output in parallel from the housing 10 of the double relay 1.

[0081] According to the illustrated embodiment, the number of wire slots 42 can match the number of connecting cables. For example, in the case of four connecting cables and four pins, there can be four corresponding wire slots 42, each for one connecting cable. When these wire slots are arranged side by side and spaced apart, the connecting cables stuck in the wire slots 42 can be guided in parallel and ultimately exit in parallel from the housing 10 of the double relay 1.

[0082] According to some embodiments of the present application, the outlet port 40 may be provided with two or more rows of cable grooves 42 for the first connecting cable 21 of the first coil 20 and the second connecting cable 23 of the second coil 22 , and a cavity 422 may be formed between the two or more rows of cable grooves 42 .

[0083] In the illustrated embodiment, two rows of cable troughs 42 are formed on the housing 10, each row having four cable troughs 42. This allows the four connecting cables to pass through the two rows of cable troughs 42 before exiting the housing 10, with each connecting cable being held in two cable troughs 42, one in front of the other. It should be understood that more rows of cable troughs 42 can be provided to meet actual application requirements. Providing multiple rows of cable troughs 42 can provide a more secure restraint for the connecting cables.

[0084] When two or more rows of wire ducts 42 are provided, a cavity 422 may be formed between two adjacent rows of wire ducts 42. When the connecting cable is assembled into the wire duct 42 of the outlet port 40, glue may be poured into the cavity 422 to enhance the stability and fastening of the connecting cable.

[0085] According to some embodiments of the present application, the double relay 1 may include an upper shell 102 and a lower shell 104, which cooperate to form a shell of the double relay 1, wherein the outlet port 40 may be formed at the interface between the upper shell 102 and the lower shell 104.

[0086] As described above, the housing 10 may be composed of an upper housing 102 and a lower housing 104. In the illustrated embodiment, the upper housing 102 may have a greater height, while the lower housing 104 may have a smaller height, so that the lower housing 104 forms a substantially plate-like structure. Thus, the connection interface between the upper housing 102 and the lower housing 104 is substantially located at the bottom of the housing 10. In this case, the cable outlet port 40 is formed substantially at the bottom of the housing 10.

[0087] According to some embodiments of the present application, the cable guiding mechanism 30 can be arranged at a substantially bottom position of the housing 10, that is, the first guiding member 32, the second guiding member 34 and the outlet port 40 are all close to the lower housing 104. In this way, when the double relay 1 is actually assembled, glue can be poured on the lower housing 104 to seal the pins, connecting cables, and the cable guiding mechanism, thereby further improving the stability of the cable and reducing interference.

[0088] According to some embodiments of the present application, the outlet port 40 may include a first half 402 and a second half 404, the first half 402 may be formed on the upper shell 102, and the second half 404 may be formed on the lower shell 104, so that when the upper shell 102 and the lower shell 104 are matched, the first half 402 and the second half 404 cooperate with each other to form the wire groove 42.

[0089] In the case where the outlet port 40 is formed at the interface between the upper housing 102 and the lower housing 104, the outlet port 40 can be formed into a two-part structure, one part corresponding to the upper housing 102 and the other part corresponding to the lower housing 104, as shown in the illustrated embodiment. The mating portions of the first half 402 and the second half 404 can have the same, similar, or complementary sizes and shapes, so that the first half 402 and the second half 404 can be mated and joined together to form the complete outlet port 40.

[0090] When the first half 402 and the second half 404 are mated and joined together, a wire groove 42 is formed. According to some embodiments, a portion of the wire groove 42 may be formed on the first half 402, and another portion of the wire groove 42 may be formed on the second half 402. When the first half 402 and the second half 404 are joined together, the portion of the wire groove 42 and the other portion of the wire groove 42 are correspondingly joined to form a complete wire groove 42. In other embodiments, most of the wire groove 42 can be formed on the first half 402, for example, a complete groove is formed on the first half 402, and the second half 404 acts as a base. When the first half 402 and the second half 404 are joined together, the groove on the first half 402 and the base on the second half 404 cooperate with each other to form the wire groove 42, or vice versa, that is, most of the wire groove 42 can be formed on the second half 404, for example, a complete groove is formed on the second half 404, and the first half 402 acts as a top cover. When the first half 402 and the second half 404 are joined together, the groove on the second half 404 and the top cover on the first half 402 cooperate with each other to form the wire groove 42.

[0091] According to some embodiments of the present application, the double relay 1 may include a fool-proof mark 44 , which may be provided near the outlet port 40 and corresponding to the corresponding wire duct 42 to facilitate identification of the connection cables received by each wire duct 42 .

[0092] like Figure 1 As shown, a foolproof mark 44 may be formed above the outlet port 40 (for example, on the upper shell 102). The foolproof mark 44 may be formed directly on the shell 10, for example, by printing, engraving, etc. The foolproof mark 44 may be a mark for identification and distinction, such as text, letters, colors, specific shapes, etc. Figure 1 In the embodiment shown, four characters in white, blue, red and black are used to represent the corresponding connecting cables. By setting the foolproof mark 44, the corresponding position of each connecting cable can be identified during assembly to prevent the occurrence of incorrect connection.

[0093] According to some embodiments of the present application, the double relay 1 may include a common connector 50, and the first connecting cable 21 of the first coil 20 and the second connecting cable 23 of the second coil 22 can be connected to the common connector 50 through the cable guiding mechanism 30, and the common connector 50 can extend to the outside of the housing 10 of the double relay 1 through the first connecting cable 21 of the first coil 20 and the second connecting cable 23 of the second coil 22.

[0094] According to the double relay 1 of the present application, the cable guide mechanism 30 is used to guide the connecting cables, so that the connecting cables can be arranged in a regular and orderly manner and exit from the housing 10, so that the connecting cables can continue to extend after exiting. At the same time, because the cable guide mechanism 30 guides the connecting cables to be arranged side by side with each other, all the connecting cables of the two relay units are finally exited together in a side-by-side arrangement from the housing 10, so that these connecting cables can be advantageously connected to a single common connector 50 without having to be connected separately. In the case where the connecting cables can continue to extend after exiting, the common connector 50 is located outside the housing 10, so that the external circuit can be conveniently connected through the common connector 50. The length of the connecting cables extending outside the housing after exiting can be selected according to actual application needs, and the model of the common connector 50 can also be selected according to different usage scenarios. This connection method is different from the prior art that requires additional connecting wires to make electrical connections between the relay and the external circuit, and is more convenient to operate.

[0095] The coil bottom outlet structure with a novel design according to the present application can be applied to integrated relays. The bottom outlet structure is orderly and concise, so that the cable can be pressed into the wire slot with appropriate pressure, without being taut or loose, ensuring smooth internal tightening and high mass production processability.

[0096] Although exemplary embodiments of the present application have been described, it will be understood by those skilled in the art that various changes and modifications may be made to the exemplary embodiments of the present application without departing substantially from the spirit and scope of the present application. Therefore, all such changes and modifications are intended to be within the scope of protection of the present application as defined by the appended claims. The present application is defined by the appended claims, and equivalents of these claims are intended to be included therein.
