Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an electrical connection mechanism and an air conditioner. Background Technology

[0002] A connector is an electronic component used to connect the flow of electricity or electrical signals. Connectors, in conjunction with bases and limiters, enable stable circuit connections. However, current connectors have complex connection structures, are inconvenient to assemble and disassemble, have low efficiency, are time-consuming and labor-intensive, and have complex molds, resulting in high production costs. Utility Model Content

[0003] The problem solved by this utility model is how to simplify the connection structure while ensuring the stability of the connection, so as to facilitate installation and disassembly, improve the efficiency of assembly and disassembly, save time and labor, reduce the complexity of the mold, reduce production costs, and improve economic benefits.

[0004] To solve the above problems, the technical solution of this utility model is implemented as follows:

[0005] Firstly, this utility model provides an electrical connection mechanism, including a connecting seat, a connecting terminal, and a base. The connecting terminal is inserted into and detachably connected to the connecting seat. The base is provided with a pin, and the connecting seat has a clearance hole. The connecting seat is inserted into the base so that the pin passes through the clearance hole. The pin is provided with a first mating structure, and the connecting terminal is provided with a spring piece having a second mating structure. The first mating structure and the second mating structure are positioned together to fix the relative positions of the base and the connecting terminal. Compared with the prior art, the electrical connection mechanism provided by this utility model, due to the use of a pin passing through the clearance hole and having a first mating structure, and a spring piece having a second mating structure, simplifies the connection structure while ensuring connection stability, facilitates installation and disassembly, improves assembly and disassembly efficiency, saves time and labor, reduces mold complexity, lowers production costs, and improves economic benefits.

[0006] Furthermore, in the first and second mating structures, one is a positioning post and the other is a positioning hole. The positioning post extends into the positioning hole and is positioned and mated with it. This fixes the relative positions of the spring and the pin, thereby fixing the relative positions of the connecting terminal and the base, facilitating the installation and removal of the connecting terminal and the base.

[0007] Furthermore, the connecting terminal includes a mating frame and a connecting end. The mating frame has a bottom wall, one end of which is connected to the connecting end along the length of the connecting terminal, and the other end is connected to a spring contact. The spring contact is bent and passes through the mating frame in the opposite direction. The connecting end is used for wiring. The connecting end can sequentially connect to the pins of the base through the mating frame and the spring contact, thereby realizing circuit conduction.

[0008] Furthermore, the bottom wall is provided with a buckle, and the connector has a locking hole, which engages with the buckle. This fixes the relative position of the bottom wall and the connector, thereby fixing the relative position of the connector terminal and the connector, facilitating the installation and removal of the connector terminal and the connector.

[0009] Furthermore, the electrical connection mechanism also includes a limiting seat, which is inserted into the connecting seat to allow the spring to extend into the limiting seat. The limiting seat has a first locking structure, and the spring has a second locking structure. The first locking structure and the second locking structure engage. The limiting seat is used to drive the spring to move, thereby disengaging the first mating structure from the second mating structure. This disengages the pins of the connecting terminal and the base, facilitating the removal of the connecting terminal and the connecting seat as a whole from the base.

[0010] Furthermore, one of the first and second snap-fit ​​structures is a hook, and the other is a slot, with the hook engaging with the slot. This fixes the relative positions of the spring and the limiting seat, thereby fixing the relative positions of the connecting terminal and the limiting seat, facilitating the installation and removal of the connecting terminal and the limiting seat.

[0011] Furthermore, there are two first and two second locking structures. The two second locking structures are arranged opposite each other along the width direction of the spring piece, and each first locking structure engages with one second locking structure. The two first locking structures and the two second locking structures work together to limit the spring piece on both sides in the width direction simultaneously, improving the engagement effect between the spring piece and the limiting seat and preventing the limiting seat from accidentally disengaging from the spring piece.

[0012] Furthermore, the number of connecting terminals, pins, and clearance holes are all multiple, and the connector has multiple insertion cavities arranged side by side. Each clearance hole communicates with one insertion cavity, and each connecting terminal is inserted into one insertion cavity. That is, the electrical connection mechanism has multiple digits, and multiple connecting terminals are connected to multiple pins in a one-to-one correspondence, which can realize the conduction of multiple circuits simultaneously, making it suitable for different scenarios and highly applicable.

[0013] Furthermore, the connecting seat is provided with a partition, and two adjacent insertion cavities are arranged opposite each other on both sides of the partition. The limiting seat has a clearance notch, and the partition mates with the clearance notch. The partition is used to separate two adjacent insertion cavities to prevent the connecting terminals in the two adjacent insertion cavities from connecting and causing a short circuit.

[0014] Secondly, this utility model provides an air conditioner including the aforementioned electrical connection mechanism. The electrical connection mechanism includes a connecting seat, a connecting terminal, and a base. The connecting terminal is inserted into and detachably connected to the connecting seat. The base is provided with a pin, and the connecting seat has a clearance hole. The connecting seat is inserted into the base so that the pin passes through the clearance hole. The pin is provided with a first mating structure, and the connecting terminal is provided with a spring piece having a second mating structure. The first and second mating structures are positioned together to fix the relative positions of the base and the connecting terminal. This air conditioner simplifies the connection structure while ensuring connection stability, facilitating installation and disassembly, improving assembly and disassembly efficiency, saving time and labor, reducing mold complexity, lowering production costs, and improving economic benefits.

Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] First Embodiment

[0028] Please refer to the reference. Figures 1 to 9 This utility model provides an electrical connection mechanism 100 for realizing power or electrical signal connection. It simplifies the connection structure while ensuring connection stability, facilitates installation and disassembly, improves assembly and disassembly efficiency, saves time and labor, reduces mold complexity, lowers production costs, and improves economic benefits.

[0029] The electrical connection mechanism 100 includes a connector 110, a connector 120, and a base 130. The connector 120 is inserted into the connector 110 and is detachably connected to the connector 110 to fix the relative position of the connector 120 and the connector 110, facilitating the installation and removal of the connector 120 and the connector 110. The base 130 is provided with a pin 131. The connector 110 has a clearance hole 111. The connector 110 is inserted into the base 130 so that the pin 131 passes through the clearance hole 111. Since the connector 120 is inserted into the connector 110 at this time, the pin 131 also extends into the connector 120. Specifically, the pin 131 is provided with a first mating structure 1311, and the connecting terminal 120 is provided with a spring piece 121 having a second mating structure 1211. The first mating structure 1311 and the second mating structure 1211 are positioned and engaged to fix the relative position of the spring piece 121 and the pin 131 in the insertion and removal direction of the connecting terminal 120, thereby fixing the relative position of the connecting terminal 120 and the base 130, facilitating the installation and removal of the connecting terminal 120 and the base 130. In this way, the connecting terminal 120 is detachably connected to both the connecting seat 110 and the base 130, simultaneously fixing the relative positions of the connecting seat 110, the connecting terminal 120, and the base 130. This simplifies the connection structure while ensuring connection stability, facilitates installation and removal, improves assembly and disassembly efficiency, saves time and labor, reduces mold complexity, lowers production costs, and improves economic benefits.

[0030] Preferably, one of the first mating structure 1311 and the second mating structure 1211 is a positioning post and the other is a positioning hole. The positioning post extends into the positioning hole and is positioned and mated with the positioning hole to fix the relative position of the spring piece 121 and the pin 131, thereby fixing the relative position of the connecting terminal 120 and the base 130, which facilitates the installation and removal of the connecting terminal 120 and the base 130.

[0031] In this embodiment, the first mating structure 1311 is a positioning post and the second mating structure 1211 is a positioning hole. That is, the pin 131 is provided with a positioning post and the spring piece 121 is provided with a positioning hole. However, it is not limited to this. In other embodiments, the first mating structure 1311 is a positioning hole and the second mating structure 1211 is a positioning post. That is, the pin 131 is provided with a positioning hole and the spring piece 121 is provided with a positioning post.

[0032] Specifically, since the spring piece 121 is elastic, during the process of the positioning post and the positioning hole engaging, the positioning post on the pin 131 first applies pressure to the spring piece 121 to overcome the elastic force of the spring piece 121 and cause the spring piece 121 to undergo elastic deformation; then the positioning post slides relative to the spring piece 121 until the positioning post moves to the position of the positioning hole of the spring piece 121. At this time, the spring piece 121 no longer resists the positioning post, and the spring piece 121 rebounds and resets under its own elastic force, and extends into the positioning hole and engages with the positioning hole to fix the relative position of the spring piece 121 and the pin 131, thereby completing the installation of the connection terminal 120.

[0033] Preferably, the second mating structure 1211 is disposed at the middle of the spring piece 121 along its width direction, so as to ensure that the spring piece 121 can apply a spring force to the second mating structure 1211 in the direction of the insert pin 131, thereby improving the stability of the mating between the second mating structure 1211 and the first mating structure 1311, that is, ensuring that the positioning pin can be accurately inserted into the positioning hole and mated with the positioning hole.

[0034] The connecting terminal 120 includes a mating frame 122 and a connecting end 123. The mating frame 122 has a bottom wall 1221. The spring piece 121 and the connecting end 123 are connected to the two ends of the bottom wall 1221, that is, along the length direction of the connecting terminal 120, one end of the bottom wall 1221 is connected to the connecting end 123, and the other end is connected to the spring piece 121. The spring piece 121 is bent and passes through the mating frame 122 in the opposite direction. The connecting end 123 is used for wiring. The connecting end 123 can be connected to the pin 131 of the base 130 through the mating frame 122 and the spring piece 121 in sequence, thereby realizing circuit conduction. Specifically, the connecting seat 110 has an insertion cavity 112 communicating with the clearance hole 111. The shape of the mating frame 122 matches the shape of the insertion cavity 112, and the mating frame 122 mates with the insertion cavity 112. The pin 131 extends into the mating frame 122 and is located on one side of the spring piece 121. In this way, both the spring piece 121 and the pin 131 are located within the mating frame 122. Under its own elastic force, the spring piece 121 tends to move towards the pin 131, so as to achieve a tight fit between the positioning post and the positioning hole.

[0035] In this embodiment, the mating frame 122, the connecting end 123, and the spring piece 121 are integrally formed to improve the connection strength. Furthermore, the mating frame 122, the connecting end 123, and the spring piece 121 are all made of conductive materials (such as copper, aluminum, or iron) to facilitate circuit conduction.

[0036] In this embodiment, the bottom wall 1221 is provided with a buckle 1222, and the connecting seat 110 is provided with a locking hole 113. The buckle 1222 engages with the locking hole 113 to fix the relative position of the bottom wall 1221 and the connecting seat 110, thereby fixing the relative position of the connecting terminal 120 and the connecting seat 110, which facilitates the installation and removal of the connecting terminal 120 and the connecting seat 110.

[0037] Preferably, the electrical connection mechanism 100 further includes a limiting seat 140. The limiting seat 140 is inserted into the connecting seat 110 so that the spring piece 121 extends into the limiting seat 140, facilitating the engagement of the spring piece 121 and the limiting seat 140. Specifically, the limiting seat 140 is provided with a first snap-fit ​​structure 141, and the spring piece 121 is provided with a second snap-fit ​​structure 1212. The first snap-fit ​​structure 141 and the second snap-fit ​​structure 1212 snap-fit ​​together to fix the relative position of the spring piece 121 and the limiting seat 140, thereby fixing the relative position of the connecting terminal 120 and the limiting seat 140, facilitating the installation and removal of the connecting terminal 120 and the limiting seat 140. In this way, the connecting terminal 120 is detachably connected to the connecting seat 110, the base 130, and the limiting seat 140 simultaneously, thereby fixing the relative positions of the four components to ensure a stable connection.

[0038] Furthermore, after the first snap-fit ​​structure 141 and the second snap-fit ​​structure 1212 are snapped together, the limiting seat 140 can overcome the elastic force of the spring piece 121 and drive the spring piece 121 to move away from the pin 131, so that the first mating structure 1311 and the second mating structure 1211 are disengaged, and the pin 131 of the connecting terminal 120 and the base 130 are separated, so that the connecting terminal 120 and the connecting seat 110 can be removed from the base 130 as a whole (the connecting terminal 120 and the connecting seat 110 are kept in a snap-fit ​​state by the cooperation of the snap 1222 and the snap hole 113). After that, the snap 1222 and the snap hole 113 can be removed as needed, so that the connecting terminal 120 can be removed from the insertion cavity 112 of the connecting seat 110.

[0039] In this embodiment, the pin 131 is disposed on the upper side of the spring piece 121. After the first snap-fit ​​structure 141 and the second snap-fit ​​structure 1212 are snapped together, the limiting seat 140 is pressed down so that the limiting seat 140 overcomes the elastic force of the spring piece 121 and drives the spring piece 121 to move downward, thereby causing the positioning pin to disengage from the positioning hole and the spring piece 121 to separate from the pin 131, which facilitates the removal of the connecting terminal 120 and the connecting seat 110 as a whole from the base 130.

[0040] Furthermore, there are two of each of the first latching structure 141 and the second latching structure 1212. The two second latching structures 1212 are arranged opposite each other along the width direction of the spring piece 121. Each first latching structure 141 latches with one second latching structure 1212. The two first latching structures 141 and the two second latching structures 1212 work together to limit the spring piece 121 on both sides in the width direction at the same time, improve the latching effect between the spring piece 121 and the limiting seat 140, and prevent the limiting seat 140 from accidentally disengaging from the spring piece 121.

[0041] Preferably, one of the first snap-fit ​​structure 141 and the second snap-fit ​​structure 1212 is a snap hook and the other is a snap groove. The snap hook and the snap groove engage to fix the relative position of the spring piece 121 and the limiting seat 140, thereby fixing the relative position of the connecting terminal 120 and the limiting seat 140, which facilitates the installation and removal of the connecting terminal 120 and the limiting seat 140.

[0042] In this embodiment, the first snap-fit ​​structure 141 is a snap hook, and the second snap-fit ​​structure 1212 is a snap groove. That is, the limiting seat 140 is provided with a snap hook, and the spring piece 121 is provided with a snap groove. However, it is not limited to this. In other embodiments, the first snap-fit ​​structure 141 is a snap groove, and the second snap-fit ​​structure 1212 is a snap hook. That is, the limiting seat 140 is provided with a snap groove, and the spring piece 121 is provided with a snap hook.

[0043] In this embodiment, the limiting seat 140 has a clearance groove 142, and two hooks are disposed in the clearance groove 142 and are disposed opposite to each other on both sides of the clearance groove 142; two slots are disposed at the free end of the spring piece 121 and are disposed opposite to each other on both sides of the spring piece 121 in the width direction. During the process of the limiting seat 140 being inserted into the connecting seat 110, the spring piece 121 simultaneously extends into the clearance groove 142. During this process, the two hooks in the clearance groove 142 respectively engage with the two slots of the spring piece 121 to realize the engagement between the spring piece 121 and the limiting seat 140, fix the relative position of the spring piece 121 and the limiting seat 140, thereby fixing the relative position of the connecting terminal 120 and the limiting seat 140.

[0044] Preferably, the number of connecting terminals 120, pins 131, and clearance holes 111 are all multiple. The connector 110 has multiple insertion cavities 112 arranged side-by-side. Each clearance hole 111 communicates with one insertion cavity 112. Each connecting terminal 120 is inserted into one insertion cavity 112, and each pin 131 extends into one connecting terminal 120. Specifically, the number of insertion cavities 112 and connecting terminals 120 is multiple, meaning the electrical connection mechanism 100 has multiple digits. By having multiple connecting terminals 120 correspondingly connected to multiple pins 131, multiple circuits can be simultaneously connected, making it suitable for different scenarios and highly adaptable.

[0045] Furthermore, the connecting seat 110 is provided with a partition 114, and two adjacent insertion cavities 112 are disposed opposite each other on both sides of the partition 114. That is, the partition 114 is used to separate two adjacent insertion cavities 112 to prevent the connecting terminals 120 in the two adjacent insertion cavities 112 from connecting and causing a short circuit. Specifically, the limiting seat 140 has a clearance notch 143. The partition 114 cooperates with the clearance notch 143 to limit the relative position of the limiting seat 140 with respect to the partition 114, thereby limiting the relative position of the limiting seat 140 with respect to the connecting seat 110. Through the snap-fit ​​between the limiting seat 140 and the connecting terminal 120, and the snap-fit ​​between the connecting terminal 120 and the connecting seat 110, a stable connection can be achieved between the limiting seat 140, the connecting terminal 120 and the connecting seat 110, preventing the limiting seat 140 from accidentally disengaging.

[0046] It should be noted that the opening direction of the clearance notch 143 is the same as the depth direction of the clearance groove 142. During the process of inserting the limit seat 140 into the connecting seat 110, the insertion direction of the limit seat 140 is the opening direction of the clearance notch 143. During this process, the partition 114 extends into the clearance notch 143, and the spring piece 121 extends into the clearance groove 142 until the partition 114 and the bottom of the clearance notch 143 abut against each other, and the first snap-fit ​​structure 141 and the second snap-fit ​​structure 1212 snap-fit ​​together. At this time, the partition 114 can stop and limit the limit seat 140 to prevent the limit seat 140 from being inserted further. The snap-fit ​​of the first snap-fit ​​structure 141 and the second snap-fit ​​structure 1212 can fix the relative position of the limit seat 140 and the connecting terminal 120, thereby fixing the relative position of the limit seat 140, the connecting terminal 120 and the connecting seat 110.

[0047] In this embodiment, there are two connecting terminals 120, two pins 131, and two clearance holes 111. The connecting seat 110 has two insertion cavities 112 arranged side by side. There is one partition 114 and one clearance notch 143. The partition 114 is disposed between the two insertion cavities 112, and there are two clearance grooves 142 in the partition 114. The limiting seat 140 is inserted into both insertion cavities 112 at the same time, so that the clearance notch 143 cooperates with the partition 114, and the spring pieces 121 of the two connecting terminals 120 extend into the two clearance grooves 142 one by one. However, it is not limited to this. In other embodiments, the number of insertion cavities 112 and connecting terminals 120 can be three or four. The number of insertion cavities 112 and connecting terminals 120 is not specifically limited.

[0048] Furthermore, the limiting seat 140 is made of an insulating material (such as plastic, rubber, etc.) and is used to isolate the multiple connection terminals 120 to prevent the multiple connection terminals 120 from connecting and causing a short circuit.

[0049] It should be noted that during the installation of the electrical connection mechanism 100, the two connecting terminals 120 are first inserted into the connecting seat 110 sequentially or simultaneously, so that the two connecting terminals 120 extend into the two insertion cavities 112 in a one-to-one correspondence. During this process, the latches 1222 of the connecting terminals 120 engage with the locking holes 113 of the connecting seat 110 to fix the relative positions of the connecting terminals 120 and the connecting seat 110. Subsequently, the connecting seat 110 with the two connecting terminals 120 inserted is inserted into the base 130. During this process, the two pins 131 of the base 130 extend into the mating frames 122 of the two connecting terminals 120 through the two clearance holes 111 in a one-to-one correspondence. When the connecting seat 110 and the base 130 are in place, the positioning pins on the pins 131 and the springs 121... The positioning holes are engaged to fix the relative positions of the connecting terminal 120 and the base 130. Then, the limiting seat 140 is simultaneously inserted into the two insertion cavities 112 so that the clearance notch 143 engages with the partition 114, and the spring pieces 121 of the two connecting terminals 120 extend into the two clearance slots 142 one by one, so that the hook of the limiting seat 140 engages with the slot of the spring piece 121 to fix the relative positions of the connecting terminal 120 and the limiting seat 140. In this way, the connecting terminal 120 is detachably connected to the connecting seat 110, the base 130 and the limiting seat 140 to fix the relative positions of the four components. The disassembly and assembly process is simple, easy to install and disassemble, and can effectively improve the efficiency of disassembly and assembly.

[0050] The electrical connection mechanism 100 of this utility model embodiment has a connection terminal 120 inserted into a connection base 110 and detachably connected to the connection base 110. A base 130 is provided with a pin 131. The connection base 110 has a clearance hole 111. The connection base 110 is inserted into the base 130 so that the pin 131 passes through the clearance hole 111. The pin 131 is provided with a first mating structure 1311. The connection terminal 120 is provided with a spring piece 121 having a second mating structure 1211. The first mating structure 1311 and the second mating structure 1211 are positioned and engaged to fix the relative positions of the base 130 and the connection terminal 120. Compared with the prior art, the electrical connection mechanism 100 provided by this utility model adopts a pin 131 that passes through the clearance hole 111 and is provided with a first mating structure 1311 and a spring piece 121 that is provided with a second mating structure 1211. Therefore, it can simplify the connection structure while ensuring the connection is stable, facilitate installation and disassembly, improve the efficiency of disassembly and assembly, save time and effort, reduce the complexity of the mold, reduce production costs, and improve economic benefits.
