Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more specifically to a high-voltage interlocking connector. Background Art

[0002] Based on safety and other needs, high-voltage connectors are usually equipped with an interlocking signal mechanism. The interlocking signal mechanism usually includes a signal wire, an interlocking female terminal and an interlocking male terminal. There are usually two interlocking female terminals and they are fixedly set in the socket of the high-voltage connector. Each interlocking female terminal is connected to a signal wire. The interlocking male terminal is usually set in the plug of the high-voltage connector. After the plug and the socket are correctly connected, the interlocking male terminal conducts the two interlocking female terminals to form a signal loop, thereby sending a signal that the plug and the socket have been correctly connected.

[0003] For plugs with flip covers, there are currently two common forms of interlocking signal mechanisms. One is to directly fix the interlocking male terminal on the inside of the flip cover. After the flip cover is flipped and closed, the interlocking male terminal follows the flip cover to move until the interlocking female terminal is connected. The other form is to set a slider and a spring in the plug, and the interlocking male terminal is set on the slider. When the flip cover is flipped and closed, the slider is pressed to overcome the elastic force of the spring and move toward the interlocking female terminal until the interlocking male terminal is connected to the interlocking female terminal.

[0004] Among the above existing technologies, the first one requires the interlocking male terminal to be fixedly installed on the flip cover by embedded injection molding or an intermediate medium plate / block. Due to the influence of processing and installation errors, the interlocking male terminal and the interlocking female terminal may not correspond correctly, resulting in poor contact. This structure also complicates the structure and manufacturing of the flip cover. The second one requires sliders, slide grooves, limiters and other structures to be set in the shell of the plug, which has high requirements for processing and manufacturing and a relatively complicated process.

[0005] Therefore, it is necessary to develop a new type of high voltage interlocking connector to replace the above-mentioned prior art. Utility Model Content

[0006] The utility model provides a high-voltage interlocking connector with a novel interlocking structure to replace the prior art, thereby achieving the effects of simplifying the structure and process and improving the tolerance of processing and installation errors.

[0007] The utility model provides a high-voltage interlocking connector, comprising a plug and a socket, wherein a disconnected interlocking circuit is provided in the socket, and a flip cover is provided on the plug, characterized in that a rod body is provided in the plug, one end of the rod body is rotatably connected to the plug, and the other end is cantilevered and provided with an interlocking piece, and a pressing portion corresponding to the rod body is provided on the inner side of the flip cover, and when the flip cover is flipped and closed, the pressing portion presses the rod body to rotate it and drives the interlocking piece to connect to the interlocking circuit; an elastic piece that applies a reverse rotation force to the rod body is also provided in the plug, and when the flip cover is flipped and opened, the elastic piece drives the rod body to rotate in the reverse direction and drives the interlocking piece to disengage from the interlocking circuit.

[0008] Optionally, a pin is fixedly installed in the plug, and one end of the rod body is rotatably connected to the pin to achieve a rotatable connection between the rod body and the plug.

[0010] Optionally, a avoidance cavity corresponding to the interlocking circuit is provided in the plug, a mounting groove is provided on the side wall of the avoidance cavity, the rod body is arranged in the mounting groove through the pin shaft, one end of the torsion spring is clamped on the rod body, and the other end is clamped with the inner wall of the mounting groove.

[0011] Optionally, the pin is protrudingly provided on the inner wall of the plug, the torsion spring is sleeved on the pin, one end of the torsion spring is clamped on the rod body, and the other end is clamped with the inner wall of the plug.

[0012] Optionally, the interlocking piece includes a sheet-shaped interlocking male terminal, the interlocking circuit includes at least two interlocking female terminals, and the ends of at least two of the interlocking female terminals are provided with relatively distributed elastic clips, and the interlocking male terminal enters between the elastic clips of at least two of the interlocking female terminals and is clamped by the elastic clips to realize the interlocking piece connecting the interlocking circuit.

[0013] Optionally, the interlocking male terminal rotation plane is located between the two opposite elastic clips.

[0014] Optionally, the rod body is made of insulating material, and the interlocking male terminal is embedded and injection-molded at the end of the rod body.

[0015] Optionally, a first limiting portion is provided at one end of the rod body that is rotatably connected to the plug. When the flip cover is flipped open, the first limiting portion abuts against an inner wall of the plug to limit an angle range of reverse rotation of the rod body.

[0016] Optionally, a second limiting portion is provided in the mounting groove, and when the flip cover is flipped open, the rod body abuts against the second limiting portion to limit the angle range of the rod body for reverse rotation.

[0017] Optionally, the angle range is 0°-45°.

[0018] Optionally, the pressing portion includes a protrusion arranged on the end surface of the flip cover facing the rod body.

[0019] The utility model has the following beneficial effects:

[0020] 1. The rod body provided in the utility model is rotatably connected in the plug, and the rod body and the flip cover are two independent components. The structure and manufacturing of the flip cover are basically not affected and will not be complicated by the provision of an interlocking structure.

[0038] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0039] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0040] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0041] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0042] like Figure 1-6 As shown, a high-voltage interlocking connector provided in this embodiment includes a plug 1 and a socket 2, a disconnected interlocking circuit is provided in the socket 2, a flip cover 3 is provided on the plug 1, a rod body 4 is provided in the plug 1, one end of the rod body 4 is rotatably connected to the plug 1, and the other end is cantilevered and provided with an interlocking piece, and a pressing portion corresponding to the rod body 4 is provided on the inner side of the flip cover 3. When the flip cover 3 is flipped over and closed, the pressing portion presses the rod body 4 to rotate it and drives the interlocking piece to connect the interlocking circuit; an elastic piece that applies a reverse rotation force to the rod body 4 is also provided in the plug 1. When the flip cover 3 is flipped over and opened, the elastic piece drives the rod body 4 to rotate in the reverse direction and drives the interlocking piece to disengage the interlocking circuit.

[0043] The above-mentioned rod body 4 is rotatably connected in the plug 1, and it and the flip cover 3 are two independent components. The structure and manufacturing of the flip cover 3 are basically not affected, and will not be complicated by the setting of the interlocking structure. Moreover, the installation position of the rod body 4 can be fine-tuned according to the actual position of the interlocking circuit during installation to ensure the correct correspondence between the interlocking part and the interlocking circuit, thereby avoiding the problem in the prior art that the interlocking male terminal 6 cannot be adjusted due to being embedded in the shell or the intermediate medium plate / block due to injection molding; in addition, the above-mentioned rod body 4 is simple to manufacture and easy to install. Compared with the slider, slide groove, limiter and other structures in the prior art and their strict matching relationship, the requirements for processing and manufacturing are lower, and the process is simpler. The rod body 4 cooperates with the elastic part to ensure that the interlocking male terminal 6 is driven out of the interlocking female terminal 7 in time when the flip cover 3 is opened, thereby ensuring a good interlocking function.

[0044] Furthermore, in order to facilitate assembly, in this embodiment, a pin shaft 5 is fixedly installed in the plug 1 , and one end of the rod body 4 is rotatably connected to the pin shaft 5 to achieve a rotatable connection between the rod body 4 and the plug 1 .

[0045] Furthermore, in order to obtain a stable and effective elastic force, in this embodiment, the elastic member is a torsion spring 51 which is inserted into the pin shaft 5 and has two ends respectively engaged with the rod body 4 and the plug 1 .

[0046] Furthermore, a avoidance cavity 12 corresponding to the interlocking circuit is provided in the plug 1, and a mounting groove 111 is provided on the side wall of the avoidance cavity 12. The rod body 4 is arranged in the mounting groove 111 through the pin shaft 5. One end of the torsion spring 51 is clamped on the rod body 4, and the other end is clamped on the inner wall of the mounting groove 111.

[0047] More specifically, Figure 4-6 As shown, in this embodiment, considering the matching relationship with other internal components of the plug 1, the avoidance cavity 12 is formed by avoiding the corresponding part of the structure of the inner core 11 installed in the plug 1, and the installation groove 111 is essentially a part of the inner core 11. The installation groove 111 is enlarged because it needs to avoid the fastening bolts used to fix the flip cover 3, and considering the size and installation factors of the torsion spring 51, therefore, in this embodiment, one end of the torsion spring 51 is clamped on the rod body 4, and the other end is actually clamped on the inner wall of the plug 1.

[0048] As an alternative to the above-mentioned detailed structure, in other embodiments, the elastic member can also be an elastic rubber block fixed in the plug and located on the rotation path of the rod body. The rod body rotates and compresses the elastic rubber block until the interlocking member is connected to the interlocking circuit. After the flip cover is opened, the rod body rotates in the opposite direction under the elastic force of the elastic rubber block until the interlocking member is disengaged from the interlocking circuit; the inner wall of the plug can also be integrally formed with a pin shaft, one end of the pin shaft is cantilevered, or one end of the pin shaft is inserted and fixed on the inner wall of the plug and the other end is cantilevered, and one end of the rod body is rotatably connected to the pin shaft, that is, a pin shaft is protruding on the inner wall of the plug, a torsion spring is sleeved on the pin shaft, and the rod body is synchronously rotatably arranged on the pin shaft, one end of the torsion spring is clamped on the rod body, and the other end is clamped with the inner wall of the plug, and the cantilevered end of the pin shaft can be fixedly sleeved with an annular anti-slip member to prevent the rod body from falling off. The above alternatives are clear and can be achieved by conventional technical means, so they will not be described in detail.

[0049] Furthermore, in order to better adapt to the rotational movement of the rod body 4, in this embodiment, the interlocking part includes a sheet-shaped interlocking male terminal 6, and the interlocking circuit includes two interlocking female terminals 7. One end of each interlocking female terminal 7 is provided with two relatively distributed elastic clips 71, and the other end is connected to an interlocking signal line 72. The interlocking male terminal 6 enters between the elastic clips 71 of the two interlocking female terminals 7 and is clamped by the elastic clips 71 to realize the interlocking part connecting the interlocking circuit. The socket 2 is also provided with an interlocking sheath 73 for fixing and protecting the interlocking female terminal 7. The end of the interlocking sheath 73 is provided with an avoidance gap for avoiding the interlocking male terminal 6 so that the interlocking male terminal 6 enters the elastic clips 71. The number of interlocking male terminals 6 and interlocking female terminals 7 can be increased according to actual needs, and the number of elastic clips 71 of each interlocking female terminal 7 can also be increased.

[0050] Furthermore, in order to ensure that the interlocking male terminal 6 is uniformly and stably clamped by the elastic clips 71 , in this embodiment, the rotation plane of the interlocking male terminal 6 is located between two opposite elastic clips 71 .

[0051] Furthermore, in order to obtain good electrical performance, prevent creepage, and reduce weight, in this embodiment, the rod body 4 is made of insulating material such as plastic, and the interlocking male terminal 6 is stamped from a metal plate such as a copper plate and embedded in the end of the rod body 4 by injection molding.

[0052] Furthermore, in order to limit the reversal angle of the rod body 4 and prevent the rod body 4 from colliding with the flip cover 3 after excessive reversal, causing the flip cover 3 to be unable to be flipped and closed, in this embodiment, a first limiting portion 41 is provided at one end of the rod body 4 that is rotatably connected to the plug 1. When the flip cover 3 is flipped open, the first limiting portion 41 abuts against the inner wall of the plug 1 to limit the angle range of the reverse rotation of the rod body 4.

[0053] As an alternative to the above-mentioned detailed structure, in other embodiments, a second limiting portion close to the flip cover can be provided in the mounting groove. When the flip cover is flipped open, after the rod body rotates in the opposite direction, the side of the rod body facing the flip cover abuts against the second limiting portion to limit the angle range of the reverse rotation of the rod body. This alternative is clear and can be achieved by conventional technical means, so it will not be described in detail.

[0054] Furthermore, in order to obtain a good use effect, the angle range of the rod body 4 reverse rotation is set to 0°-45°, that is, the maximum angle of the rod body 4 reverse rotation is 45°, and the rod body 4 can only reversely rotate from 0° to 45°.

[0055] In this embodiment, the reverse rotation angle range is further reduced to 0°-20°, that is, the maximum reverse rotation angle of the rod body 4 is 20°, and the rod body 4 can only reversely rotate 20°.

[0056] Furthermore, in order to adapt to the pressing rod body 4 , in this embodiment, the pressing portion includes a protrusion 31 arranged on the end surface of the flip cover 3 facing the rod body 4 , and the protrusion 31 is integrally formed on the flip cover 3 .

[0057] During specific use, when the flip cover 3 is in the open state, the rod body 4 rotates in the opposite direction to a position of 20° under the drive of the torsion spring 51. At this time, the interlocking male terminal 6 is away from the interlocking female terminal 7, the interlocking circuit is disconnected and no signal is generated, driving the flip cover 3 to flip until the protrusion 31 presses the rod body 4 to rotate. When the flip cover 3 is closed, the interlocking male terminal 6 on the rod body 4 is connected to the interlocking female terminal 7, thereby connecting the interlocking circuit, and the interlocking circuit sends a signal.

[0058] When the flip cover 3 needs to be opened, the above actions are performed in reverse, and finally the rod body 4 is driven by the torsion spring 51 to rotate in the opposite direction to a position of 20°, and the interlocking male terminal 6 is away from the interlocking female terminal 7 to disconnect the interlocking circuit, and the interlocking circuit does not generate a signal.

[0059] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
