[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] Reference Figure 1 and Figure 2 As shown, a self-locking connector of an embodiment of the utility model includes a mounting seat 100, a pressure rod 200 and a reset assembly 300. The mounting seat 100 is mainly composed of an interface 110 and a rubber core 120. The interface 110 is installed on one side of the rubber core 120, and the interface 110 is used for external terminal matching. Three mounting blocks 130 are arranged at intervals along the width direction of the mounting seat 100 on the side of the rubber core 120 away from the interface 110, and a copper bus 140 and a bent wire pressing spring 150 are respectively arranged between two adjacent mounting blocks 130.

[0033] Specifically, the copper busbar 140 is installed at the bottom of the rubber core 120 and is located between two adjacent mounting blocks 130. The end of the copper busbar 140 is bent and inserted into the interface 110. A first mounting column 131 is provided between the two adjacent mounting blocks 130. The middle section of the bent wire pressing spring 150 cooperates with the first mounting column 131 so that the wire pressing spring 150 can be rotatably arranged above the copper busbar 140.

[0034] Reference Figure 3 As shown, it can be understood that two adjacent mounting blocks 130 are respectively provided with self-locking grooves 134 on opposite sides, and the two self-locking grooves 134 are symmetrically arranged on both sides of the wire pressing spring piece 150 .

[0035] A second mounting column 132 is provided between two adjacent mounting blocks 130, and a pressure rod 200 is located above the pressure wire spring piece 150. One end of the pressure rod 200 is rotatably connected to the second mounting column 132, and the other end is provided with a rotatable center axis. Guide rods 210 are symmetrically provided on both sides of the pressure rod 200, and the two guide rods 210 are respectively connected to the two ends of the center axis by fasteners such as screws, pins or rivets, so that the two guide rods 210 are synchronously rotated and installed on both sides of the pressure rod 200.

[0036] In addition, the second mounting post 132 can also be directly integrated with one end of the pressure rod 200, and then the second mounting post 132 is rotatably connected to the mounting block 130, so as to realize the rotatable installation of the pressure rod 200. The connection structure between the pressure rod 200 and the mounting block 130 is not specifically limited here, and the user can freely set it according to the actual situation, as long as the pressure rod 200 can be rotated and pressed against the wire pressing spring 150.

[0037] Guide columns 211 are respectively provided on the opposite sides of the two guide rods 210. The guide columns 211 are located at the end of the guide rod 210 away from the pressure rod 200. The guide columns 211 cooperate with the self-locking groove 134 and are suitable for locking or releasing the pressure rod 200. An arc-shaped pressing portion 220 is provided on the side of the pressure rod 200 facing the wire pressing spring piece 150. The locked pressure rod 200 drives the wire pressing spring piece 150 to cooperate with the copper bus 140 and clamp the external cable through the pressing portion 220. The end of the pressure rod 200 away from the second mounting column 132 is also connected to an operating portion 230 for the user to press.

[0038] By providing the guide post 211, the friction between the guide rod 210 and the self-locking groove 134 can be reduced as much as possible, so that the guide rod 210 can move smoothly along the self-locking groove 134, ensuring the movement stability of the pressure rod 200 and improving the user's use feel. By providing the arc-shaped pressing portion 220, the friction between the pressure rod 200 and the wire pressing spring sheet 150 can be reduced as much as possible, reducing the wear of the wire pressing spring sheet 150, while ensuring the self-locking stability of the connector, and further improving the user's use feel.

[0039] Reference Figure 1 and Figure 2 As shown, it can be understood that the mounting base 100 is also connected to a block 160, which is located at one end of the copper bus 140 away from the interface 110 and between two adjacent mounting blocks 130, and the block 160 is provided with a threading hole for the wire to pass through, and the block 160 is provided with a filling portion 161, and the filling portion 161 is located between the two guide rods 210 to avoid the wire pressing spring 150 and the copper bus 140 being directly exposed to the outside after the cable is installed on the connecting machine, thereby improving the structural integrity of the connector while improving the safety of use and the structural tightness of the connector.

[0040] Reference Figure 4 As shown, it can be understood that the mounting block 130 is provided with a spacer block 135, and the spacer block 135 is provided with a partition 1351, which is a protruding structure protruding toward the wire pressing spring 150 in a direction perpendicular to the bottom surface of the self-locking groove 134. The self-locking groove 134 includes a common section 1341, a locking section 1342 and an unlocking section 1343. The common section 1341 is located above the spacer block 135, and the locking section 1342 and the unlocking section 1343 are separated by the spacer block 135 (that is, the locking section 1342 and the unlocking section 1343 are respectively located on both sides of the spacer block 135), the locking section 1342 and the common section 1341 are located on the same side of the spacer block 135 and are connected, and the partition 1351 is located between the common section 1341 and the unlocking section 1343 to separate the common section 1341 from the unlocking section 1343.

[0041] In other words, a groove is provided on the side wall of the mounting block 130 facing the wire pressing spring sheet 150, the top of the groove extends upward for a section and forms a common section 1341, and the spacer block 135 is arranged in the groove to divide the groove into a locking section 1342 and an unlocking section 1343. Along the radial direction of the interface 110 (i.e., the front and rear direction of the connector), the locking section 1342 and the wire pressing spring sheet 150 are respectively located on both sides of the unlocking section 1343, and an end of the spacer block 135 close to the common section 1341 is provided with a partition 1351 for separating the common section 1341 from the unlocking section 1343.

[0042] The partition portion 1351 is provided with a guide slope 1352, and the guide slope 1352 is arranged toward the unlocking section 1343 to guide the guide rod 210 to enter the common section 1341 from the unlocking section 1343. The bottom end of the partition block 135 is provided with a recessed portion 1353. The locking section 1342 is connected to the unlocking section 1343 through the recessed portion 1353 to form a locking point 1344, and the locking point 1344 can be snap-fitted with the guide column 211.

[0043] It should be noted that due to the recessed portion 1353, i.e., the groove structure formed by the upward recess of the bottom end of the spacer 135, the locking section 1342 and the unlocking section 1343 are connected through the recessed portion 1353 to form a locking point 1344, i.e., the bottom end of the locking section 1342 and the bottom end of the unlocking section 1343 are respectively bent and extended toward the recessed portion 1353 and are respectively connected with the recessed portion 1353, thereby preventing the transition between the locking point 1344 and the locking section 1342 and the unlocking section 1343 from being too smooth, causing the guide column 211 to detach from the locking point 1344 under the influence of a slight external force, thereby ensuring the locking effect of the locking point 1344 on the guide column 211.

[0044] In the initial state, that is, when the guide post 211 is located at the top of the common section 1341, the user presses the pressure rod 200, and the pressure rod 200 drives the guide rod 210 to move downward, and the common section 1341 guides the guide post 211 to move toward the spacer 135. Under the obstruction of the partition 1351, the guide post 211 enters the locking section 1342 from the common section 1341, and as the pressure rod 200 continues to move downward, the guide post 211 reaches the bottom of the locking section 1342. Then the user releases the pressure rod 200, and under the action of the reset assembly 300, the pressure rod 200 rotates. At the same time, the bent and extended part of the locking section 1342 guides the guide post 211 from the locking section 1342 to the locking point 1344, and the locking point 1344 is engaged with the guide post 211, so that the guide rod 210 is locked by locking the guide rod 210. At this time, the locked pressure rod 200 drives the wire pressing spring piece 150 to cooperate with the copper bus 140 and clamp the external cable through the pressing part 220, that is, the pressing part 220 drives the wire pressing spring piece 150 to rotate, so that the end of the wire pressing spring piece 150 away from the pressing part 220 rotates toward the copper bus 140, thereby cooperating with the copper bus 140 and clamping the external cable.

[0045] The user presses the pressure rod 200 again, and the bent and extended part of the unlocking section 1343 guides the guide column 211 to disengage from the locking point 1344, thereby releasing the guide rod 210 by unlocking the guide rod 210. Then, with the cooperation of the reset assembly 300 and the guide slope 1352, the guide column 211 enters the common section 1341 from the unlocking section 1343 to achieve reset.

[0046] By providing the common section 1341, the locking section 1342 and the unlocking section 1343, the common section 1341 and the locking section 1342 are connected to form a locking point 1344, so that the self-locking groove 134 is decomposed into several specific curved paths, so that the locking and releasing of the pressure rod 200 can be achieved by just pressing. The user can lock the pressure rod 200 by pressing the pressure rod 200 once, and unlock and release the pressure rod 200 by pressing the pressure rod 200 again. The locking and releasing functions of the pressure rod 200 are achieved through a specific curved path, and the functional components are simple and easy to use, and easy to match, which can effectively simplify the connector structure and facilitate the user's assembly and use.

[0047] Reference Figure 4 As shown, it should be supplemented that the locking section 1342 and the unlocking section 1343 are both arranged at an angle. Specifically, along the radial direction of the interface 110, the bottom end of the locking section 1342 is offset in the direction away from the wire pressing spring piece 150, and the unlocking section 1343 is also inclined in the same direction, so that the self-locking groove 134 adapts to the moving path of the guide rod 210, thereby ensuring the structural rationality of the self-locking groove 134, and at the same time also plays a certain role in avoiding the wire pressing spring piece 150, which makes it convenient for users to set the wire pressing spring piece 150 and improves the overall structural tightness of the connector.

[0048] Among them, along the direction perpendicular to the bottom wall of the self-locking groove 134, the height of the partition 1351 is less than the depth of the self-locking groove 134 (i.e., the height of the side wall of the self-locking groove 134). The height of the partition 1351 is set to be less than the depth of the self-locking groove 134, while ensuring that the partition 1351 can separate the common section 1341 and the unlocking section 1343, and avoiding the subsequent problems such as the guide rod 210 entering the unlocking section 1343 from the common section 1341 when the user presses the pressure rod 200, and thus preventing the partition 1351 from being too protruding, and when the guide inclined surface 1352 guides the guide rod 210 from the unlocking section 1343 to enter the common section 1341, the guide column 211 is separated from the unlocking section 1343, thereby affecting the cooperation between the guide rod 210 and the self-locking groove 134, effectively improving the structural rationality of the self-locking groove 134, and ensuring the cooperation stability between the guide rod 210 and the self-locking groove 134.

[0049] Reference Figure 4 As shown, it can be understood that the spacer 135 is provided with a limiting portion 1354, and the limiting portion 1354 is located on one side of the partition portion 1351. The limiting portion 1354 is extended toward the wire pressing spring sheet 150 in a direction perpendicular to the bottom wall of the self-locking groove 134, and the end face of the limiting portion 1354 facing the wire pressing spring sheet 150 is flush with the end face of the mounting block 130 facing the wire pressing spring sheet 150.

[0050] Since the side walls of the spacer block 135 are respectively the side walls of the locking section 1342 and the unlocking section 1343, by setting the limiting portion 1354, the limiting portion 1354 can thicken the thickness of the spacer block 135, thereby enhancing the separation effect of the spacer block 135, and playing a role in the guide column 211 in the locking section 1342 or the unlocking section 1343, to prevent the guide column 211 from directly entering the unlocking section 1343 from over the spacer block 135 from the locking section 1342 when the user locks the pressure rod 200; or to prevent the guide column 211 from directly entering the locking section 1342 from over the spacer block 135 from the unlocking section 1343 when the user unlocks the pressure rod 200, thereby ensuring the structural rationality of the self-locking groove 134, preventing the guide column 211 from being offside, and effectively improving the movement stability of the guide column 211.

[0051] Continue to refer to Figure 4As shown, it can be understood that the mounting base 100 is provided with a first check block 136, and the first check block 136 is located between the locking section 1342 and the locking point 1344. The first check block 136 is protruded toward the wire pressing spring 150 in a direction perpendicular to the bottom wall of the self-locking groove 134. The first check block 136 is provided with a first inclined surface 1361 on the side facing the locking section 1342. The first inclined surface 1361 is used to guide the guide rod 210 from the locking section 1342 to enter the locking point 1344. The first check block 136 is provided with a first plane 1362 on the side away from the locking section 1342. The first plane 1362 is perpendicular to the bottom wall of the self-locking groove 134.

[0052] By setting the first check block 136, after the first inclined surface 1361 of the first check block 136 guides the guide rod 210 from the locking section 1342 to the locking point 1344, the first plane 1362 can play a blocking role, preventing the guide rod 210 from returning to the locking section 1342 along the original path, ensuring the unidirectional movement of the guide column 211 between the locking section 1342 and the locking point 1344, making it convenient for the locking point 1344 to quickly lock the guide rod 210, thereby improving the user experience and the locking efficiency of the connector.

[0053] At the same time, the mounting base 100 is provided with a second check block 137, and the second check block 137 is located between the unlocking section 1343 and the locking point 1344. The first check block 136 is provided with a first inclined surface 1361 on the side facing the locking point 1344, and the first inclined surface 1361 is used to guide the guide rod 210 from the locking point 1344 into the unlocking section 1343. The first check block 136 is provided with a second plane 1372 on the side away from the locking point 1344, and the second plane 1372 is perpendicular to the bottom wall of the self-locking groove 134.

[0054] By setting the second check block 137, after the second inclined surface 1371 of the second check block 137 guides the guide rod 210 from the locking point 1344 to the unlocking section 1343, the second plane 1372 can play a blocking role, preventing the guide rod 210 from returning to the locking point 1344 along the original path, ensuring the unidirectional movement of the guide column 211 between the locking point 1344 and the unlocking section 1343, and facilitating the guide rod 210 to quickly detach from the locking point 1344, thereby further improving the user experience and improving the unlocking efficiency of the connector.

[0055] Reference Figure 1 As shown, it can be understood that the reset assembly 300 is respectively connected to the pressing rod 200 and the wire pressing spring sheet 150 to drive the pressing rod 200 and the wire pressing spring sheet 150 to reset.

[0056] Specifically, refer to Figure 5As shown, the reset assembly 300 includes a first rebound plate 310, the middle section of the first rebound plate 310 is located between the wire pressing spring plate 150 and the first mounting column 131, and a support column 133 is provided between two adjacent mounting blocks 130. One end of the first rebound plate 310 is fixedly connected to the support column 133, and the other end is located above the rotating shaft of the wire pressing spring plate 150 (that is, the first mounting column 131) and abuts against the inner side surface of the wire pressing spring plate 150 (that is, the surface of the wire pressing spring plate 150 facing the first mounting column 131).

[0057] When the user presses the locking lever 200, the lever 200 rotates and compresses the pressing spring sheet 150 through the pressing portion 220. At the same time, the pressing spring sheet 150 rotates and compresses the end of the first rebound sheet 310 that abuts against the inner side of the pressing spring sheet 150. Since one end of the first rebound sheet 310 is fixedly connected to the support column 133, the first rebound sheet 310 is elastically deformed. The user presses the locking lever 200 again, and the guide column 211 is disengaged from the locking point 1344 to unlock the lever 200. At the same time, the pressing portion 220 releases the pressing of the pressing spring sheet 150, so that the pressing spring sheet 150 releases the pressing of the first rebound sheet 310. The elastically deformed first rebound sheet 310 releases the elastic force and drives the pressing spring sheet 150 to rotate, completing the reset of the pressing spring sheet 150.

[0058] By setting the first rebound sheet 310, while ensuring that the wire pressing spring sheet 150 can be quickly reset, the structure of the connector is further simplified, and the convenience of connector assembly is improved. In addition, compared with the traditional spring reset structure, the first rebound sheet 310 is more suitable for the wire pressing spring sheet 150, further improving the structural rationality of the connector.

[0059] Reference Figure 1 and Figure 2 It can be understood that the reset assembly 300 includes a second rebound sheet 320, which is connected to the end of the pressure rod 200 away from the guide rod 210 and abuts against the inner side surface of the rubber core 120 (that is, the end surface of the rubber core 120 away from the interface 110).

[0060] Specifically, the pressure rod 200 is usually a plastic-coated part composed of a metal core and a plastic shell that wraps the metal core. Therefore, when the pressure rod 200 is produced by injection molding, the second rebound piece 320, the second mounting column 132 and the pressure rod 200 can be directly injection molded into an integral part to ensure the connection stability of the second rebound piece 320, the second rebound piece 320 and the second mounting column 132. When the user installs the pressure rod 200 to the second mounting column 132, the second rebound piece 320 also automatically abuts against the inner side of the plastic core 120, further improving the convenience of connector assembly. In addition, the second rebound piece 320 cooperates with the first rebound piece 310 to further improve the unlocking efficiency of the connector while improving the structural consistency of the connector.

[0061] It should be added that, since the first rebound sheet 310 also presses against the wire pressing spring sheet 150 when the user presses the locking pressure rod 200 (that is, when the guide column 211 moves in the locking section 1342), in order to prevent the guide column 211 from moving to the bottom end of the guide locking section 1342 when the user releases the pressure rod 200, the guide column 211 returns to the common section 1341 along the locking section 1342, the mounting seat 100 is provided with a second check block 137 and a third check block 138. The third check block 138 is located at the bottom end of the locking section 1342 to prevent the guide column 211 from returning to the common section 1341 along the locking section 1342, thereby ensuring the smoothness of the connector after use. The structure of the third check block 138 can be specifically referred to the first check block 136 and will not be repeated here.

[0062] It is understandable that, by providing the pressure rod 200 and the wire pressing spring 150, the pressure rod 200 compresses the wire pressing spring 150 through the pressing part 220, so that the wire pressing spring cooperates with the copper bar 140 and clamps the external cable, and the cable assembly does not require a cumbersome assembly process, and only the cable needs to be stripped, which can adapt to a wide range of wire gauges and ensure the stability of cable installation. By providing the self-locking groove 134, the user presses the pressure rod 200 once, and the common end and locking section 1342 of the self-locking groove 134 cooperate with the guide rod 210, so that the guide column 211 enters the locking point 1344, and the pressure rod 200 is locked, and then the spring is locked, which is convenient for the user to install the cable; the user presses the pressure rod 200 again, and the unlocking section 1343 and the common end of the self-locking groove 134 cooperate with the guide rod 210, so that the guide column 211 is separated from the locking point 1344 and returns to the common end, so that the pressure rod 200 is released, and then the spring is unlocked, which is convenient for the user to disassemble the cable. The cooperation between the self-locking groove 134 and the guide column 211 can greatly simplify the assembly structure and operation steps of the connector. The locking and releasing of the pressure rod 200 can be achieved by pressing only. Press once to lock, and press again to unlock and release, which improves the assembly efficiency of the connector and meets the design requirements of lightweight and simplified connectors.

[0063] It is understandable that there are multiple copper bars 140, and two mounting blocks 130 are symmetrically arranged on both sides of each copper bar 140, and self-locking grooves 134 are arranged on the opposite sides of two adjacent mounting blocks 130, so that two symmetrical self-locking grooves 134 are symmetrically arranged on both sides of each copper bar 140, and the wire pressing spring piece 150, the pressure rod 200, and the reset assembly 300 are arranged one by one with the copper bar 140. Among them, the copper bar 140 can be arranged in multiple rows along the width direction of the mounting seat 100, or multiple rows can be arranged in the upper and lower rows (at this time, the copper bar 140 located at the bottom is reversely installed with the corresponding assembly to ensure that the pressure rod 200 is located outside the connector). The number and arrangement of the copper bars 140 are not specifically limited here, and the user can select the appropriate number and layout according to the external terminals actually connected, as long as the connector is ensured to be stably adapted to connect the external terminals.

[0064] Reference Figure 6 As shown, it can be understood that the self-locking connector also includes a shell 400, which is sleeved on the end of the rubber core 120 away from the interface 110, that is, the shell 400 covers the mounting block 130, the stopper 160 and the pressure rod 200, and the shell 400 is provided with an observation window 410, which is located on the same side of the wire pressing spring 150 and the copper bus 140, and the mounting block 130 is provided with an opening corresponding to the position of the observation window 410.

[0065] By providing the observation window 410, the user can directly observe the installation status of the cable through the observation window 410, thereby avoiding problems such as the cable not being properly inserted, the copper bus 140 or the wire pressing spring 150 not being in sufficient contact with the cable, etc., thereby ensuring the stable installation of the cable, further improving the user experience, and improving the appearance of the connector.

[0066] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
