Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a coupling connector structure. Background Art

[0002] Connectors, also known as connectors, plugs, and sockets, generally refer to electrical connectors—devices that connect two active components, transmitting current or signals. Connectors are a component that electronic engineers frequently encounter. Connectors connect more than just electrical current. With the rapid development of optoelectronics, fiber optic systems now use light as the carrier for signal transmission. Glass and plastic replace the wires in ordinary circuits, but connectors are also used in optical signal pathways, serving the same purpose as electrical connectors.

[0003] Existing connectors are unstable when inserted and removed, which affects installation efficiency, and the connection installation is unstable, which affects signal transmission. Utility Model Content

[0011] In the first position, the long arm contacts the lock tongue, and the long arm maintains elastic force on the lock tongue, so that the locking column is inserted into the lock hole. At this time, the male connector and the female connector are in a connected and locked state;

[0012] In the second position, press the two unlocking buttons at the same time to disengage the locking column from the lock hole. At this time, the male head and the female head are in a separable state. At the same time, the long arm is squeezed and generates a rebound force, which is used to return the lock tongue from the second position to the first position after the two unlocking buttons are released.

[0013] Furthermore, the male head cavity has a positioning structure for relatively fixing the middle part of the spring piece.

[0014] Furthermore, the positioning structure includes a guide block and a stop block fixed in the male head cavity, and a placement groove for inserting the middle part of the spring piece is formed between the guide block and the stop block.

[0015] Furthermore, the inner side of the unlocking button has a guide groove that cooperates with the guide block.

[0016] Furthermore, the inner side of the stopper has a positioning protrusion, and the middle part of the elastic piece has a groove that cooperates with the positioning protrusion.

[0017] Furthermore, the other end of the unlocking button located in the male cavity has a limiting arm, the other end of the spring is a short arm, the limiting arm contacts the limiting block in the male cavity, and the short arm contacts the limiting arm.

[0018] Furthermore, an L-shaped through groove is provided on the side of the male head close to the end of the lock tongue for the lock tongue and the locking column to be inserted and moved.

[0034] See also Figures 1 to 7, the utility model provides a technical solution:

[0035] A coupling connector structure, comprising:

[0036] Male connector 1, female connector 2, spring piece 7 and interlocking portion;

[0037] Two unlocking buttons 3 are installed on the side of the male connector 1 and can be pressed and moved relative to the male connector 1. One end of the unlocking button 3 located in the cavity of the male connector 1 has a lock tongue 12 and the other end has a limit arm 13;

[0038] The spring piece 7 is located inside the male connector 1, with the middle portion relatively fixed, and one end is a long arm 10 and the other end is a short arm 11;

[0039] The limiting arm 13 contacts the limiting block 27 in the cavity of the male connector 1 , and the short arm 11 contacts the limiting arm 13 ;

[0040] The interlocking portion includes a lock hole 15 provided on the outside of the lock tongue 12 and a locking post 16 in the cavity of the female head 2;

[0041] In the first position, the long arm 10 contacts the lock tongue 12, and the long arm 10 maintains elastic force on the lock tongue 12, so that the locking column 16 is inserted into the lock hole 15. At this time, the male connector 1 and the female connector 2 are in a connected and locked state;

[0042] In the second position, the two unlocking buttons 3 are pressed at the same time to disengage the locking column 16 from the lock hole 15. At this time, the male head 1 and the female head 2 are in a separable state. At the same time, the long arm 10 is squeezed and generates a rebound force, and is used to restore the lock tongue 12 from the second position to the first position after the two unlocking buttons 3 are released.

[0043] Specifically, the cavity of the male head 1 has a positioning structure 4 for relatively fixing the middle part of the spring piece 7. The positioning structure 4 includes a guide block 6 and a stop block 9 fixed in the cavity of the male head 1, and a placement groove 8 for inserting the middle part of the spring piece 7 is formed between the guide block 6 and the stop block 9. The inner side of the unlocking button 3 has a guide groove 5 that cooperates with the guide block 6. The inner side of the stop block 9 has a positioning protrusion 17, and the middle part of the spring piece 7 has a groove 18 that cooperates with the positioning protrusion 17. The positioning protrusion 17 cooperates with the groove 18 to position the spring piece 7 so that the spring piece 7 is relatively fixed in the placement groove 8, ensuring that the spring piece 7 can be compressed and rebound after compression. The side of the male head 1 close to the end of the lock tongue 12 is provided with an L-shaped through groove 14 for the lock tongue 12 and the locking column 16 to be inserted and moved.

[0044] like Figure 1-4As shown, when in use, in the first position, the male connector 1 and the female connector 2 are in a connected locked state. In the connected locked state, the two unlocking buttons 3 slightly protrude from the outside of the male connector 1, which makes it easier to press the two unlocking buttons 3 at the same time. The spring clip 7 pre-presses the unlocking button 3: that is, the long arm 10 of the spring clip 7 pre-presses the lock tongue 12, that is, the short arm 11 of the spring clip 7 pre-presses the limit arm 13, so that the lock hole 15 of the lock tongue 12 is plugged into the locking column 16 in the cavity of the female connector 2, so that the interlocking portion formed by the lock hole 15 and the locking column 16 of the male connector 1 and the female connector 2 can always remain in a locked state, realizing the connected locked state of the male connector 1 and the female connector 2.

[0045] like Figure 5 As shown, when the male head 1 and the female head 2 need to be separated, the unlocking button 3 needs to be pressed. Since the unlocking button 3 has a guide groove 5, the guide groove 5 slides relative to the guide block 6, thereby driving the lock tongue 12 of the unlocking button to slide, thereby unlocking the locking column 16 and the lock hole 15, thereby separating the male head 1 and the female head 2.

[0046] The guide groove 5 slides relative to the guide block 6 to make the unlock button press more stable. Figure 3 As shown in FIG5 , the outside of the top of the locking tongue 12 has an oblique / chamfered angle c which guides the sliding in function with the oblique angle a of the locking post 16. The oblique angle b of the lock hole 15 also has a guiding function, thereby facilitating the cooperation of the locking post 16 and the lock hole 15.

[0047] Specifically, the male connector 1 has a four-core power cord 23, the female connector 2 has a plug-in portion 21, a wire groove 19 and a first wire hole 20 in the male connector 1, the plug-in portion 21 has a second wire hole 22, each first wire hole 20 is aligned with the second wire hole 22, the four-core power cord 23 is located in the wire groove 19, and the connector extends into the first wire hole 20, and the power cord is connected to the second wire hole 22 of the plug-in portion 21, so that the electrical signal connection between the male connector 1 and the female connector 2 can be realized.

[0048] Specifically, such as Figure 6 and Figure 7 As shown, there is also an anti-fool structure 24 between the male connector 1 and the female connector 2. The anti-fool structure 24 includes a semicircular boss 25 located at the step d on the back side of the male connector 1, and a socket 26 located on the inner wall of the back side of the female connector 2. The semicircular boss 25 and the socket 26 are plugged in together.

[0049] In order to prevent the male connector 1 and the female connector 2 from being plugged in reverse, the anti-mute structure 24 reverses the direction of the four-core power cord 23 (three 220V voltage lines plus one signal line) on the male connector 1 and the power cord (on the female connector 2).

[0050] The driving form of the male connector 1 and the unlocking button 3 is as follows: the opposite-sex spring piece 7 has an outward force pushing the unlocking button 3, and the unlocking button 3 and the lock tongue 12 have a certain elastic deformation. This deformation can deform the lock tongue 12 when the unlocking button 3 is stationary, thereby realizing the bevel / chamfered angle c to match the bevel angle a on the locking column 16 on the female connector 2, which can easily guide the locking column 16 into the lock hole 15, so that the locking mode of the male connector 1 and the female connector 2 can be successfully locked without pressing the unlocking button 3.

[0051] In the present invention, when the unlock button 3 is pressed, the locking column 16 is separated from the lock hole 15, thereby separating the male head 1 and the female head 2. After releasing the pressing, the spring piece 7 reintroduces the locking column 16 into the lock hole 15, realizing the connection locking state of the male head 1 and the female head 2. In this way, through the effect of elastic pressing and quick reset, the male head 1 and the female head 2 are conveniently elastically plugged in and stably connected through the front locking column 16 and the lock hole 15.

[0052] The coupling connector structure of the present invention is preferably used for connecting power lines or signal lines of a cooling and heating blanket or a cooling and heating blanket device.

[0053] The undescribed parts of the present invention are existing or known technologies.

[0054] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
