Description

Technical Field

[0001] This utility model belongs to the field of electrical connection technology, and in particular relates to a concealed snap-fit ​​electrical connector structure. Background Technology

[0002] Electrical connectors are essential components in electronic systems for achieving electrical interconnection. They are primarily used to connect various components and devices in a circuit, completing the closure and opening of the circuit. They typically consist of two parts: a plug (female) and a socket (male), capable of transmitting current or signals.

[0003] For example, Chinese utility model patent document CN223181482U discloses a buckle-type connector assembly, which addresses the problem that existing male and female connectors require manual tightening of nuts to securely connect the female and male connectors, and also require manual loosening of the nuts to separate them. This connection method is cumbersome, inconvenient, and time-consuming, and the nuts are prone to falling off due to aging after prolonged use. Specifically, the assembly includes a male connector and a female connector, the male connector being pluggable into the female connector; the male connector includes a male body and a first terminal, the male body having a insertion cavity; one end of the first terminal extends into the male body, and the other end extends into the insertion cavity; the female connector includes a female body and a second terminal, the female body having an insert portion with a mounting hole; one end of the second terminal extends into the female body, and the other end extends into the mounting hole; the insert portion is inserted into the insertion cavity, and the first terminal is inserted into the second terminal. The insertion cavity is provided with a non-foolproof protrusion. The end of the insertion part facing the male end body has a non-foolproof groove, and the non-foolproof protrusion is adapted to the non-foolproof groove. The upper end of the male end body is provided with a first fastening seat, which has a snap-fit ​​hole. The upper end of the female end body is provided with a second fastening seat. The upper end of the second fastening seat extends an elastic arm towards the male end body. The upper side of the elastic arm is provided with a snap-fit ​​part. The end of the elastic arm facing the male end body has a pressing part. The pressing part passes through the snap-fit ​​hole and protrudes outside the first fastening seat. The snap-fit ​​part is snapped into the snap-fit ​​hole. When the male connector is inserted into the female connector, the pressing part can be pressed down to make the elastic arm press down, so that the snap-fit ​​part can pass through the snap-fit ​​hole and be held in the snap-fit ​​hole. When you want to remove it, you can press the pressing part to make the snap-fit ​​part exit the snap-fit ​​hole for quick insertion and removal. This achieves a snap-fit ​​connection, which is easy to use, quick to insert and remove, and will not cause loosening or falling off due to aging.

[0004] The technical solutions disclosed in the aforementioned patent documents employ a snap-fit ​​structure to achieve a fixed connection between the male and female ends. This structure is simple and easy to operate. However, the snap-fit ​​structure is an exposed structure, which is aesthetically unappealing and allows even non-professionals to operate it, posing a safety hazard. Utility Model Content

[0005] The purpose of this utility model is to provide a concealed snap-fit ​​electrical connector structure. The snap-fit ​​structure is concealed, the overall appearance is more aesthetically pleasing, and it can prevent unauthorized operation, thereby improving safety.

[0006] To achieve the above objectives, this utility model provides a concealed snap-fit ​​electrical connector structure, including a first connector and a second connector. The first connector includes a first housing and a first electrical terminal disposed within the first housing. The second connector includes a second housing and a second electrical terminal disposed within the second housing. It also includes a sliding sleeve slidably fitted onto the first housing. At least one side of the first housing has an elastic arm, and the free end of the elastic arm has a hook. The outer side of the second housing has a snap fastener for engaging with the hook. An inner side of the sliding sleeve has a pressing member that abuts against the elastic arm, pushing the sliding sleeve and pressing the elastic arm to disengage the hook from the snap fastener.

[0007] Furthermore, the inner side of the sliding sleeve is also provided with a clearance groove, which is used to avoid the elastic arm.

[0008] Furthermore, a first limiting member is provided on the outer side of the first housing, which extends into the clearance groove to cover the opening at one end of the clearance groove.

[0009] Furthermore, the inner wall of the clearance groove is also provided with a blocking member, which is used to limit the first limiting member.

[0010] Furthermore, a second limiting member is provided on the outer side of the second housing, and a third limiting member is provided on the inner side of the sliding sleeve. The third limiting member is used to limit the second limiting member.

[0011] Furthermore, the extrusion member is disposed on the third limiting member.

[0012] Furthermore, the elastic arms are provided on both sides of the first housing, and the buckles are provided on both outer sides of the second housing.

[0013] Furthermore, the hook portion is provided with a downwardly extending compression slope, and the top surface of the buckle is provided with a guide slope.

[0014] Furthermore, the bottom of the first housing extends downward to form a plug-in portion, which has an annular groove and a sealing ring inside the annular groove; the upper end of the second housing has a sleeve, which is connected to the plug-in portion; one end of the first electrical terminal extends into the plug-in portion; and one end of the second electrical terminal extends into the sleeve.

[0015] Furthermore, the second electrical terminal includes an arc-proof terminal, which includes a terminal body, a resistor, and a conductor. The terminal body is fixedly connected to the second housing, and a mounting hole is provided at the end of the terminal body. One end of the resistor is connected to the mounting hole, and the other end is connected to the conductor. An insulating element is provided between the conductor and the terminal body, and a protective element is provided at the end of the conductor.

[0016] The concealed snap-fit ​​electrical connector structure provided in this embodiment of the present invention has at least the following technical effects: 1. When the first connector and the second connector are inserted, the second housing extends into the sliding sleeve, the second electrical terminal is inserted into the first electrical terminal, and the latch pushes the elastic arm to deform until the latch engages with the hook, thus connecting and securing the first connector and the second connector. When it is necessary to separate the first connector and the second connector, push the sliding sleeve, the pressing member inside the sliding sleeve abuts against the elastic arm, and the elastic arm deforms elastically, causing the hook to disengage from the latch, thus separating the first connector and the second connector.

[0017] 2. Because the hook and buckle engage within the sliding sleeve, the overall structure is concealed, resulting in a more aesthetically pleasing design. After the first and second connectors are mated, applying opposing forces to them alone will not achieve separation, thus preventing safety hazards caused by misoperation or operation by unqualified personnel.

[0029] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0030] In one embodiment of the concealed snap-fit ​​electrical connector of this utility model, please refer to... Figure 1 and Figure 2 The concealed snap-fit ​​electrical connector of this embodiment is used for high-current transmission. Specifically, it includes a first connector 100, a second connector 200, and a sliding sleeve 300. The first connector 100 can be connected to a power supply device, and the second connector 200 can be connected to a power consumption device. After the second connector 200 is plugged into the first connector 100, the power supply device can supply power to the power consumption device.

[0031] Reference Figures 2 to 4 The first connector 100 includes a first housing 110 and a first electrical terminal 120 disposed within the first housing 110. Specifically, two first connection holes are provided within the first housing 110, and each first connection hole is provided with a first electrical terminal 120. One end of the first electrical terminal 120 is provided with a plug hole 121, and the other end is provided with a first wiring hole 122. The conductor end of the wire can extend into the first wiring hole 122 and the electrical properties are fixed by crimping.

[0032] Reference set Figure 2 , Figure 6 and Figure 7 The second connector 200 includes a second housing 210 and a second electrical terminal 220 disposed within the second housing 210. Specifically, the second housing 210 has two second connection holes, each containing a second electrical terminal 220. When the second connector 200 is connected to the first connector 100, the second electrical terminal 220 is inserted into the insertion hole 121 of the first electrical terminal 120, making the first electrical connector 100 and the second electrical connector 200 electrically connected. Furthermore, for better wiring, an elastic sleeve 160 is provided within the insertion hole 121, and the elastic sleeve 160 has several spiral grooves. Therefore, when the second electrical terminal 220 is inserted into the insertion hole 121, it is easier to insert the second electrical terminal 220 and the stability of conductivity is increased.

[0033] Furthermore, referring to Figure 2 , Figure 3 , Figure 6 and Figure 7To prevent arcing when the second connector 200 is energized and connected to the first connector 100, one of the second energized terminals 220 is an arc-resistant terminal. The arc-resistant terminal includes a terminal body 221, a resistor 222, and a conductor 223. The terminal body 221 is fixedly connected to the second housing 210, and a mounting hole is provided at one end of the terminal body 221. One end of the resistor 222 is connected to the mounting hole, and the other end is connected to the conductor 223. An insulating element 224 is provided between the conductor 223 and the terminal body 221, and a protective element 225 is provided at the end of the conductor 223. Specifically, when the arc-resistant terminal is inserted into the corresponding insertion hole 121 of the first energized terminal 120, the conductor 223 first conducts electricity with the first energized terminal 120. Because a resistor is provided between the conductor 223 and the terminal body 221, the second connector 200 and the first connector 100 are connected at the moment of connection, but the current is small, thus avoiding the problem of arcing caused by a sudden increase in current.

[0034] Furthermore, referring to Figure 2 , Figure 3 , Figure 6 and Figure 7 To facilitate the installation and fixation of the first power terminal 120 and the second power terminal 220, a first mounting cavity 111 is provided in the first housing 110, and a second mounting cavity 211 is provided in the second housing 210. A first stepped hole is provided at the upper end of the first connecting hole, and a second stepped hole is provided at the bottom end of the second connecting hole. A first limiting seat 140 is provided in the first mounting cavity 111, and a first limiting sleeve 130 is provided in the first stepped hole. The upper end of the first limiting sleeve 130 abuts against the bottom of the first limiting seat 140. The first power terminal 120 is also provided with a first limiting step, and an elastic baffle 131 is formed inward on the first limiting sleeve 130. The end of the elastic baffle 131 is supported on the first limiting step. Therefore, under the action of the first limiting seat 140 and the first limiting sleeve 130, the first power terminal 120 is limited within the first housing 110. The second mounting cavity 211 is provided with a second limiting seat 240, and the second step hole is provided with a second limiting sleeve 230. The lower end of the second limiting sleeve 230 abuts against the top of the second limiting seat 240. The second electrical terminal 220 is also provided with a second limiting step. The second limiting sleeve 230 is formed with a second elastic baffle 231 on the inward side. The end of the second elastic baffle 231 is supported on the second limiting step. Therefore, under the action of the second limiting seat 240 and the second limiting sleeve 230, the second electrical terminal 220 is limited in the second housing 210.

[0035] Reference Figure 1 , Figure 2 and Figure 5The sliding sleeve 300 is slidably fitted onto the first housing 110, and at least one side of the first housing 110 is provided with an elastic arm 150. Preferably, both sides of the first housing 110 are provided with elastic arms 150. The free end of the elastic arm 150 is provided with a hook portion 151, and the outer side of the second housing 210 is provided with a buckle 250 that engages with the hook portion 151. The inner side of the sliding sleeve 300 is provided with a pressing member 310, which abuts against the elastic arm 150. When the sliding sleeve 300 is pushed to slide, the pressing member 310 presses the elastic arm 150, causing the hook portion 151 to disengage from the buckle 250. Specifically, when the first connector 100 and the second connector 200 are plugged in, the second housing 210 extends into the sliding sleeve 300, the second electrical terminal 220 plugs into the first electrical terminal 120, and the latch 250 pushes the elastic arm 150 to deform until the latch 250 engages with the hook 151, thus connecting and fixing the first connector 100 and the second connector 200. When it is necessary to separate the first connector 100 and the second connector 200, the sliding sleeve 300 is pushed, and the pressing member 310 inside the sliding sleeve 300 abuts against the elastic arm 150. The elastic arm 150 elastically deforms, causing the hook 151 to disengage from the latch 250, thus separating the first connector 100 and the second connector 200. Because the overall engaging structure of the hook 151 and the latch 250 is located inside the sliding sleeve 300 when engaged, a hidden engagement is achieved, making the overall structure more aesthetically pleasing. After the first connector 100 and the second connector 200 are mated, separation cannot be achieved by applying opposing forces to the first connector 100 and the second connector 200 alone, thus avoiding safety hazards caused by misoperation or operation by non-professionals.

[0036] Furthermore, refer to Figure 2 and Figure 5 The inner side of the sliding sleeve 300 is also provided with a relief groove 301, which is used to avoid the elastic arm 150. The extrusion member 310 is disposed in the relief groove 301.

[0037] Furthermore, refer to Figures 2 to 4 The outer side of the first housing 110 is also provided with a first limiting member 112, which extends into the relief groove 301 and covers the opening of one end of the relief groove 301.

[0038] Furthermore, refer to Figure 2 and Figure 5 The inner wall of the clearance groove 301 is also provided with a blocking member 302. The blocking member 302 is used to limit the first limiting member 112, thereby limiting the sliding stroke of the sliding sleeve 300 and preventing the elastic arm 150 from being broken due to excessive movement of the sliding sleeve 300.

[0039] Furthermore, refer to Figure 2The outer side of the second housing 210 is also provided with a second limiting member 212, and the inner side of the sliding sleeve 300 is also provided with a third limiting member 320, which is used to limit the second limiting member 212. After the second connector 200 is inserted into the first connector 100, the second limiting member 212 and the third limiting member 320 abut against each other, which can prevent the sliding sleeve 300 from slipping off from the direction of the second connector 200. Furthermore, the pressing member 310 is provided on the third limiting member 320.

[0040] Furthermore, refer to Figures 2 to 4 , Figure 6 and Figure 7 The hook portion 151 is provided with a downwardly extending pressing slope 152, and the pressing member 310 cooperates with the pressing slope 152. When the sliding sleeve 300 slides upward, the pressing frame 310 pushes the pressing slope 152, thereby deforming the elastic arm 150. The top surface of the buckle 250 is also provided with a guide slope 251. When the second connector 200 mates with the first connector 100, the guide slope 251 can cooperate with the pressing slope 152 to push the elastic arm 150 to deform elastically, making it easier for the buckle 250 to cooperate with the hook portion 151.

[0041] Furthermore, refer to Figures 2 to 4 The bottom of the first housing 110 extends downward to form a connector 113, which has an annular groove 114 and a sealing ring 115 within it. The upper end of the second housing 210 has a sleeve, with a buckle 250 positioned on the outside of the sleeve. When the sleeve is engaged with the connector 113, the sealing ring 115 provides a waterproof seal. One end of the first electrical terminal 120 extends into the connector 113; one end of the second electrical terminal 220 extends into the sleeve.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
