[0003] The existing magnetic latching relay coil voltage input connection structure has the following disadvantages:

The anti-error mounting part serves to install the connector to fix the connector assembly to the housing of the relay. The anti-error mounting part limits the position of the connector relative to the anti-error mounting part, which plays a role in limiting and positioning the position of the connector. The anti-error mounting part will interfere with the position of the connector to achieve an anti-mistake function, that is, the connector can only be connected to the anti-mistake mounting part at a specific position, which is equivalent to constraining the position of multiple signal plug-in holes set on the connector, ensuring the uniformity of the arrangement order of multiple relay coil pins, avoiding confusion and reverse connection, and thus improving the qualified rate of the finished relay product.

After the relay coil pin is plugged into the signal plug-in hole, the voltage signal is transmitted to the coil via the relay coil pin, causing the coil to generate a magnetic field change when charged. A mismatch-proofing mounting member is disposed within the relay housing and connected to a connector. The mismatch-proofing mounting member serves to mount the connector and secure the connector assembly to the relay housing. The mismatch-proofing mounting member limits the position of the connector relative to the mismatch-proofing mounting member, thereby defining and positioning the connector. The mismatch-proofing mounting member interferes with the position of the connector, achieving a foolproofing function. This means that the connector can only be connected to the mismatch-proofing mounting member in a specific position. This is equivalent to constraining the position of multiple signal plug-in holes provided on the connector, ensuring the uniformity of the arrangement order of the multiple relay coil pins, avoiding confusion and reverse connection, and thereby improving the qualified rate of the finished relay product.

[0065] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0066] This embodiment provides a relay voltage input connection structure applicable to the field of relay technology. Figure 1-3 As shown, the relay voltage input connection structure includes a connector assembly 2 and a plurality of relay coil pins 1. The plurality of relay coil pins 1 actually serve as the lead-out ends of the relay coil. The connector assembly 2 includes a connector 21. The connector 21 is provided with a plurality of signal plug-in holes 2122. The plurality of relay coil pins 1 are correspondingly plugged into the plurality of signal plug-in holes 2122.

[0067] This embodiment provides a relay voltage input connection structure. The signal plug-in hole 2122 provides an installation position for the relay coil pin 1. The relay coil pin 1 serves as a voltage input. The relay coil pin 1 is plugged into the signal plug-in hole 2122 to transmit the voltage signal to the coil through the relay coil pin 1, so that the coil generates a magnetic field change when charging.

[0068] It should be noted that the connector 21 has a rectangular parallelepiped-like shape. The height of the connector 21 is defined as the first direction, the length of the connector 21 is defined as the second direction, and the width of the connector 21 is defined as the third direction. The first, second, and third directions are mutually perpendicular. It is understood that the multiple relay coil pins 1 are arranged along the first direction. In other words, the arrangement direction of the multiple relay coil pins 1 is the first direction.

[0069] In one embodiment, the connector assembly 2 further includes a plurality of signal wires 22 arranged along a first direction. The plurality of signal wires 22 are correspondingly plugged into the signal plug-in holes 2122 along a second direction and electrically connected to the plurality of relay coil pins 1. The signal plug-in holes 2122 provide mounting locations for the signal wires 22, which serve as voltage inputs. The signal wires 22 and the relay coil pins 1 are respectively disposed on either side of the connector 21 along the second direction. Once the signal wires 22 and the relay coil pins 1 are plugged into the signal plug-in holes 2122, an electrical connection is established between the signal wires 22 and the relay coil pins 1. This allows the voltage signal to be transmitted to the coil via the signal wires 22 and the relay coil pins 1, causing the coil to generate a magnetic field change when charged.

[0070] It can be understood that since the multiple signal lines 22 are arranged along the first direction, that is, the multiple signal lines 22 are arranged on the connecting member 21 in a certain order, the multiple signal lines 22 and the corresponding multiple relay coil pins 1 are correspondingly arranged and electrically connected to each other to realize the voltage transmission process.

[0071] The existing signal line 22 is covered with a heat shrink tube, and the signal line 22 and the relay coil pin 1 are connected by welding. The production process is complicated and the production efficiency is relatively low. In addition, multiple signal lines 22 are easily confused and connected in reverse, affecting the use effect of the relay.

[0072] To solve this problem, Figure 1-3 As shown, the relay voltage input connection structure provided in this embodiment further includes a mismatch prevention mounting member 3, which is disposed on the relay housing 100 and connected to the connector 21. The mismatch prevention mounting member 3 is configured to limit the position of the connector 21 relative to the mismatch prevention mounting member 3, thereby locating the connector 21 so that the multiple signal lines 22 are electrically connected to the multiple relay coil pins 1.

[0073] The relay voltage input connection structure provided in this embodiment is provided with a misalignment-proofing mounting member 3 disposed on the relay housing 100 and connected to the connector 21. The misalignment-proofing mounting member 3 serves to mount the connector 21, thereby securing the connector assembly 2 to the relay housing 100. The misalignment-proofing mounting member 3 limits the position of the connector 21 relative to the misalignment-proofing mounting member 3, thereby limiting and positioning the position of the connector 21. The misalignment-proofing mounting member 3 interferes with the position of the connector 21, achieving a foolproofing function. That is, the connector 21 can only be connected to the misalignment-proofing mounting member 3 in a specific position. This is equivalent to constraining the position of the multiple signal plug-in holes 2122 provided on the connector 21, ensuring the uniformity of the arrangement order of the multiple relay coil pins 1, avoiding confusion and reverse connection, and thereby improving the qualified rate of the finished relay product.

[0074] It can be understood that after the multiple signal plug-in holes 2122 are positionally constrained by using the anti-error mounting parts 3, since the multiple signal lines 22 are correspondingly plugged into the multiple signal plug-in holes 2122, it is equivalent to constraining the multiple signal lines 22 in position, thereby ensuring the uniformity of the arrangement order of the multiple signal lines 22, so that the multiple signal lines 22 can be electrically connected to the multiple relay coil pins 1, reducing the situation where the signal lines 22 are connected in reverse due to confusion in the line sequence, and the qualified rate of the finished relay products is higher.

[0075] In one embodiment, the error-proofing mounting member 3 is extended along the first direction and arranged side by side with the relay coil pin 1 along the third direction.

[0076] By extending the error-proofing mounting member 3 along the first direction, the error-proofing direction of the error-proofing mounting member 3 aligns with the arrangement direction of the multiple relay coil pins 1, thereby preventing incorrect connection of multiple signal lines 22. Furthermore, arranging the error-proofing mounting member 3 and the relay coil pins 1 side by side along the third direction is equivalent to positioning the error-proofing mounting member 3 next to the relay coil pins 1. This not only avoids interference with the position of the relay coil pins 1 but also prevents incorrect connection.

[0077] In one embodiment, Figure 4-Figure 5 As shown, the anti-error mounting part 3 includes a mounting portion 31 and an anti-error portion 32. The mounting portion 31 is arranged on the housing 100 of the relay and is detachably connected to the connector 21. The anti-error portion 32 is arranged on the mounting portion 31. The anti-error portion 32 is used to limit the position of the connector 21 relative to the mounting portion 31.

[0078] The mounting portion 31 has a strip-shaped structure and is fixed to the relay housing 100. It is removably connected to the connector 21 through the mounting portion 31. The mounting portion 31 prevents the connector 21 from falling off and secures it, ensuring the positional stability of the connector assembly 2. The anti-error portion 32 is provided on the mounting portion 31, providing a mounting location for the anti-error portion 32. The anti-error portion 32 defines and positions the connector 21, restricting the connector 21 to a specific position before it can connect to the mounting portion 31. This provides positioning and error prevention, thereby reducing confusion and reverse connection of the signal line 22.

[0079] In one embodiment, the connector 21 is provided with an insertion hole 2111 corresponding to the anti-error portion 32 , and the anti-error portion 32 is passed through the insertion hole 2111 and slidably engaged therewith.

[0080] Among them, the anti-error part 32 is specifically a columnar structure, and the anti-error part 32 can also be called a positioning column. A socket 2111 is provided corresponding to the anti-error part 32 through the connecting part 21. The anti-error part 32 can be passed through the socket 2111 and slidably matched with it. While playing a guiding role, it also plays a role of initial pre-positioning between the connector component 2 and the anti-error mounting part 3 when the connector component 2 is installed, so as to ensure the position accuracy of the installation of the connector component 2.

[0081] It should be noted that the anti-error part 32 can be a square column or a cylinder, and the socket 2111 can be a square hole or a round hole. This embodiment does not limit the structure and shape of the anti-error part 32 and the socket 2111, and can be adjusted according to actual production conditions. As long as the anti-error part 32 and the socket 2111 are compatible, they are within the protection scope of this embodiment.

[0082] It should be noted that the end of the anti-error portion 32 close to the connector assembly 2 can be a tapered structure, that is, the end of the anti-error portion 32 can be called a tip portion, which facilitates the anti-error portion 32 to be inserted into the socket 2111.

[0083] In one embodiment, a plurality of relay coil pins 1 are arranged along a first direction, and distances between two ends of the mounting portion 31 along the first direction and the anti-error portion 32 are different.

[0084] It should be noted that since the arrangement direction of the multiple signal lines 22 is the first direction, the first direction can also be the height direction, length direction and width direction along the relay housing 100. In this embodiment, the first direction is taken as the height direction of the housing 100 as an example. At this time, the connector assembly 2 is connected to the lead-out end of the coil in a vertical insertion manner.

[0085] If the anti-mistake portion 32 is located at the center of the mounting portion 31, then the anti-mistake portion 32 can be inserted into the insertion hole 2111 of the connector 21 regardless of whether the connector 21 is upright or inverted, and the position of the connector 21 relative to the anti-mistake portion 32 does not differ significantly, making it difficult to achieve the anti-mistake function. By making the distances between the anti-mistake portion 32 and the two ends of the mounting portion 31 along the first direction different, that is, the anti-mistake portion 32 is not located at the center of the mounting portion 31 along the first direction, it acts as a directional indicator, so that the anti-mistake mounting member 3 and the connector 21 can only be connected when the connector 21 is in either the upright or inverted state, which means that the connector 21 is in the correct installation position. Otherwise, even if the anti-error portion 32 is at least partially inserted into the socket 2111, some positions of the connector 21 are outside the mounting portion 31 or other positions of the connector 21 are inside the mounting portion 31, that is, at least part of the structure of the connector 21 cannot perfectly fit with the mounting portion 31. At this time, it means that the connector 21 is in an incorrect installation position and the connector 21 needs to be rotated 180° to change its direction.

[0086] It should be noted that, in some other embodiments, if multiple signal lines 22 are arranged along the second direction, for example, the length direction of the relay housing 100, that is, the second direction, the first direction and the second direction are perpendicular to each other, and the distances between the two ends of the mounting portion 31 along the second direction and the anti-error portion 32 are different. The principles and structures are similar, so they will not be described in detail.

[0087] In one embodiment, Figure 4-Figure 5 As shown, the connector 21 includes a positioning portion 211 and a connecting portion 212. The positioning portion 211 is detachably connected to the mounting portion 31. The jack 2111 is arranged on the positioning portion 211. The connecting portion 212 is connected to the positioning portion 211. The signal plug-in hole 2122 is arranged on the connecting portion 212. That is, the connection position between the signal line 22 and the relay coil pin 1 is arranged inside the connecting portion 212.

[0088] The positioning portion 211 is provided with a socket 2111, which provides a location for the socket 2111. Furthermore, the positioning portion 211 is detachably connected to the mounting portion 31, and the positioning portion 211 essentially serves to mount the positioning portion 3. The connecting portion 212 is connected to the positioning portion 211, forming an integral structure between the connecting portion 212 and the positioning portion 211. The signal line 22 and the relay coil pin 1 are respectively disposed on opposite sides of the connecting portion 212 along the second direction. The connecting portion 212 serves as an intermediate connection between the signal line 22 and the relay coil pin 1. This is equivalent to the signal line 22 and the relay coil pin 1 being located on opposite sides of the connecting portion 212 along the second direction, thereby preventing significant interference between the signal line 22 and the relay coil pin 1. Furthermore, after the anti-mistake portion 32 is plugged into the socket 2111, the signal line 22 and the relay coil pin 1 can directly connect. By setting the connection position between the signal line 22 and the relay coil pin 1 inside the connecting part 212, the connection position between the signal line 22 and the relay coil pin 1 is prevented from being exposed. This is equivalent to hiding the connection position between the signal line 22 and the relay coil pin 1 inside the connecting part 212. While playing a dust-proof and protective role, the connecting part 212 also serves as a connecting support.

[0089] In one embodiment, Figure 5-Figure 6 As shown, one of the positioning portion 211 and the mounting portion 31 is provided with a hook 2112 , and the other is provided with a buckle 311 , and the hook 2112 is engaged with the buckle 311 .

[0090] Compared with the welding connection and fixing method in the prior art, the hook 2112 is connected to the buckle 311 to achieve a detachable connection between the positioning part 211 and the mounting part 31. The connection has good stability, is convenient for installation and disassembly, and is convenient for subsequent maintenance. It has a simple structure and is easy to operate. There is no need to perform additional operations such as installing heat shrink tubes, which saves labor and time costs and improves installation production efficiency.

[0091] It should be noted that the hook 2112 or buckle 311 provided on the mounting portion 31, the mounting portion 31 and the anti-error portion 32 are an integrally formed structure, that is, the anti-error mounting part 3 can be directly formed, reducing the parts assembly process and having a relatively low production cost.

[0092] In one embodiment, a receiving cavity 2113 is provided on the side of the positioning portion 211 facing the anti-error mounting component 3 , and the receiving cavity 2113 is used to accommodate the mounting portion 31 so that the connection position between the hook 2112 and the buckle 311 is set inside the positioning portion 211 .

[0093] By providing a receiving cavity 2113 on the side of the positioning portion 211 facing the anti-error mounting member 3, the receiving cavity 2113 provides a space for the mounting portion 31. When the mounting portion 31 is accommodated in the receiving cavity 2113, it is equivalent to the mounting portion 31 being embedded in the positioning portion 211. Compared with a structure in which the mounting portion 31 is exposed relative to the positioning portion 211, the structure is compact and occupies relatively little space. By arranging the connection between the hook 2112 and the buckle 311 inside the positioning portion 211, it is equivalent to preventing the connection between the hook 2112 and the buckle 311 from being exposed or protruding and occupying a large space, thereby saving space.

[0094] Specifically, in this embodiment, the mounting portion 31 is provided with a buckle 311, and the positioning portion 211 is provided with a hook 2112 as an example. This is equivalent to the male end hook 2112 being provided inside the female end, making full use of the internal space of the mounting portion 31, and the space utilization rate is relatively high.

[0095] In one embodiment, the error-proofing mounting member 3 of the relay voltage input connection structure and the relay housing 100 are integrally formed. By forming the error-proofing mounting member 3 and the relay housing 100 as an integral structure, the assembly steps and time between parts are reduced, thus saving production costs.

[0096] It can be understood that the mounting portion 31 and the anti-error portion 32 of the anti-error mounting member 3 are also an integrally formed structure.

[0097] It is understandable that the housing 100 of the relay is made of insulating materials such as plastic, and the housing 100 and the anti-error mounting member 3 are integrally formed by injection molding, which reduces the number of parts assembly steps, has a high degree of automated production, and saves production costs.

[0098] In the actual production process, when there are side holes, side recesses or protrusions on the plastic part that are different from the mold opening direction, the protruding parts will hinder the demolding of the plastic part after molding.

[0099] To this end, the hook 2112 provided in this embodiment is disposed on the mounting portion 31 along the height direction of the relay housing 100 ; or, the buckle 311 is disposed on the mounting portion 31 along the height direction of the relay housing 100 .

[0100] The height direction of the housing 100 is the first direction, which is also the opening and closing direction of the upper and lower molds. If a hook 2112 is provided on the mounting portion 31, the hook 2112 is provided along the height direction of the housing 100, rather than along the length or width direction of the housing 100; if a buckle 311 is provided on the mounting portion 31, the buckle 311 is provided along the height direction of the housing 100, rather than along the length or width direction of the housing 100. This makes the setting direction of the hook 2112 or the buckle 311 consistent with the mold opening direction of the upper and lower molds. While achieving the integrated molding of the error-proofing mounting member 3 and the housing 100, the mold does not need to be provided with a side drawer or slider structure, the structure of the upper and lower molds is simple, and the production cost is low.

[0101] In one embodiment, there are multiple hooks 2112 and buckles 311, and the multiple hooks 2112 are correspondingly engaged with the multiple buckles 311. The multiple hooks 2112 are respectively disposed on both sides of the mounting portion 31 along the height direction of the relay housing 100.

[0102] The multiple hooks 2112 are correspondingly engaged with the multiple buckles 311, creating multiple engagement points between the anti-error mounting member 3 and the connector assembly 2, thereby improving the connection stability between the anti-error mounting member 3 and the connector assembly 2. The multiple hooks 2112 are disposed on either side of the mounting portion 31 along the first direction, and the arrangement of the hooks 2112 and buckles 311 aligns with the opening and closing direction of the upper and lower molds, simplifying the molds and production process, thereby reducing production costs.

[0103] In one embodiment, Figure 7-11 As shown, the signal line 22 is detachably connected to the connection portion 212. By detachably connecting the signal line 22 to the connection portion 212, the installation and removal of the signal line 22 are facilitated, and the connection of each signal line 22 is relatively independent, which is convenient for maintenance when damaged during use.

[0104] Specifically, a connection terminal is provided at the end of the signal line 22, and the connection terminal is provided with a signal plug-in hole 2122. When the relay coil pin 1 is inserted into the signal plug-in hole 2122, the relay coil pin 1 and the soft wire of the signal line 22 contact each other, thereby achieving electrical conduction between the relay coil pin 1 and the signal line 22. A locking tongue 2123 is provided inside the connection terminal. The shape of the locking tongue 2123 is similar to a V-shaped structure, and the two side arms of the V-shaped structure respectively abut the relay coil pin 1 and the connection portion 212. By abutting one side arm of the V-shaped structure against the relay coil pin 1, the position of the relay coil pin 1 is fixed, thereby ensuring the reliability of the connection between the relay coil pin 1 and the soft wire of the signal line 22. The connection portion 212 is provided with a locking hole 2121 corresponding to the locking tongue 2123. The other side arm of the V-shaped structure is engaged with the locking hole 2121 to ensure the fixation between the locking tongue 2123 and the connection portion 212. It is understandable that, since the V-shaped lock tongue 2123 has a certain elasticity, the elasticity of the lock tongue 2123 itself can simultaneously ensure the fixing effect of the lock tongue 2123, the relay coil pin 1 and the connecting portion 212.

[0105] It is understandable that the installation and fixing process of the signal line 22 does not require heat shrink tubing and wire welding, which reduces the number of production personnel and improves the production qualification rate.

[0106] This embodiment also provides a relay, which includes a housing 100, a coil and the above-mentioned relay voltage input connection structure. The coil is arranged in the housing 100, and the relay coil pin 1 of the relay voltage input connection structure is actually the lead-out end of the coil.

[0107] The relay provided in this embodiment is provided with a coil in a housing 100 , and the housing 100 serves to accommodate and protect the coil.

[0108] It should be noted that the relay is specifically an electromagnetic relay, comprising a contact assembly, an electromagnetic assembly, an armature assembly, and a push-button. The permanent magnet within the armature assembly magnetically attracts the contact assembly, maintaining it in either a normally open or normally closed state. Signal line 22 is electrically connected to relay coil pin 1 to transmit a voltage signal to the coil. This pulsed electrical signal triggers the electromagnetic assembly to drive the armature assembly, which in turn displaces the push-button. This displacement of the push-button switches the contact assembly between the normally open and normally closed states.

[0109] In one embodiment, the relay further includes a load terminal, which is at least partially disposed within the housing 100 .

[0110] The contact assembly includes a movable spring and a stationary contact terminal. One end of the movable spring and one end of the stationary contact terminal contact or move away from each other to switch between a normally open state and a normally closed state. The load terminal is connected to the other end of the movable spring and the other end of the stationary contact terminal, respectively. When one end of the movable spring and one end of the stationary contact terminal contact each other, the movable spring, the stationary contact terminal, and the load terminal form a closed circuit.

[0111] In one embodiment, housing 100 includes a base plate 101, a first side plate 102, and a second side plate 103. First side plate 102 is perpendicularly mounted to base plate 101, with the load terminals at least partially extending from first side plate 102. Second side plate 103 is perpendicularly mounted to base plate 101. First and second side plates 102, 103 are adjacent and perpendicular to each other. The error-proofing mounting member 3 of the relay voltage input connection structure is mounted on second side plate 103.

[0112] The first and second side panels 102, 103 are perpendicularly mounted on and surround the base panel 101, allowing the housing 100 to accommodate and protect components such as the coil. By positioning the anti-error mounting member 3 on the second side panel 103, the load terminals are at least partially extended from the first side panel 102. This means that the load terminals and the anti-error mounting member 3 correspond to two adjacent side panels. Since both the load terminals and the anti-error mounting member 3 protrude from the housing 100, the space occupied by the load terminals and the anti-error mounting member 3 along the third direction is reduced, thereby reducing the height of the relay.

[0113] At the same time, a through slot 1031 (such as Figure 5 As shown, the relay coil pin 1 is inserted into the through slot 1031, allowing it to be led out of the second side plate 103. The anti-error mounting member 3 corresponds to the second side plate 103 adjacent to the coil lead end. Based on the principle of proximity, this facilitates the extraction of the relay coil pin 1 from the housing 100. Furthermore, the through slot 1031 and the anti-error mounting member 3 are arranged side by side along the third direction, simplifying the mold structure and eliminating the need for core pulling.

[0114] It can be understood that the load terminal and the relay coil pin 1 are respectively led out from the first side plate 102 and the second side plate 103, two adjacent side plates, and the structure is compact and occupies relatively little space.

[0115] In one embodiment, the second side plate 103 is provided with a recessed portion, and the anti-error mounting member 3 is disposed within the recessed portion. The recessed portion provides at least partial accommodation space for the anti-error mounting member 3. Utilizing the internal space of the recessed portion, the protrusion distance of the anti-error mounting member 3 relative to the second side plate 103 along the second direction is reduced, further reducing the overall size of the relay along the second direction.

[0116] It should be noted that the anti-error mounting part 3 of the relay voltage input connection structure extends along the first direction, and the arrangement direction of the multiple signal lines 22 is the first direction. The first direction is set vertically relative to the base plate 101. At this time, the setting direction of the anti-error mounting part 3 is the same as the mold opening and closing direction, which simplifies the demolding process and makes the mold simple.
