Description

Technical Field

[0001] The utility model relates to the technical field of electronic connectors, and more specifically, to a secondary lock for preventing accidental touch of a horn connector. Background Art

[0002] A connector is also called a plug-in unit, which is also called a connector and a socket in China. Generally, it refers to an electrical plug-in unit, that is, a device connecting two active devices, transmitting current or signals. The male end and the female end can transmit information or current after contact, and it is also called a connector. The horn connector gets its name because its shape is similar to that of a horn. It usually consists of a plastic shell, terminals, metal pins, etc. The plastic shell plays a role in protecting and fixing the terminals. The terminals are used to realize the connection of the circuit, and the metal pins are inserted into the jacks of the circuit board to realize the connection with the circuit board.

[0003] However, the existing horn connectors have the following problems when in use:

[0004] (1) After the board end of the horn connector completes the soldering process on the PCB, the assembly operation of the wire end to the board end of the horn connector starts. However, during this process, if there is an accidental touch of the horn plastic shell, then the wire end inside is very likely to easily detach from the board end of the horn connector. This situation may bring many inconveniences and potential risks to the subsequent equipment operation and maintenance.

[0005] (2) Secondly, after the wire end and the board end of the horn connector are assembled, if the board end and the wire end of the horn connector are assembled together but not assembled to the predetermined position and flow into the next process, problems such as loose connection and poor contact may occur due to not being assembled to the predetermined position, bringing great risks to the normal operation of the equipment during subsequent use.

[0006] The utility model can prevent the phenomenon that the wire end detaches from the board end of the horn connector due to accidental touch of the horn plastic shell, make the connection between the board end and the wire end of the horn connector more reliable, and can effectively prevent misoperation and prevent products that are not assembled in place from flowing into the next stage. Summary of the Utility Model

[0007] The purpose of the utility model is to solve the technical problems proposed in the above background art, and provide a secondary lock for preventing accidental touch of a horn connector.

[0008] To achieve the above object, the present utility model provides the following technical solutions: A secondary lock for preventing accidental touch of a horn connector, comprising: a connector, a secondary lock is clamped above the left side of the connector, the connector is composed of two front and rear plate ends, moving grooves are provided at both the left and right ends of the connector, wire ends are arranged in the moving grooves, a base is fixedly installed at the bottom of the secondary lock, the middle of the secondary lock is clamped on the wire end, and the base is clamped with the front and rear ends of the connector.

[0009] Further preferred solution: Grooves are provided at both the front and rear ends of the wire end, and limiting grooves are provided at both the front and rear ends of the connector.

[0010] Further preferred solution: The inside of the secondary lock is clamped with the groove, and the base is clamped with the limiting groove.

[0011] Further preferred solution: Clasps are fixedly installed at both the front and rear ends of the inner wall of the secondary lock, and a horn buckle is fixedly installed at the bottom of the base.

[0012] Further preferred solution: The clasp is provided in a matching manner with the groove, and the bottom of the clasp is chamfered, and the clasp slides into the groove through the bottom chamfer to be clamped with the wire end.

[0013] Further preferred solution: The horn buckle is provided in a matching manner with the limiting groove, and the bottom of the horn buckle is chamfered, and the horn buckle slides into the limiting groove through the bottom chamfer to be clamped with the connector.

[0014] Beneficial effects:

[0015] 1. By providing a clasp and a groove, the chamfer design at the bottom of the clasp enables it to slide into the groove more smoothly. The two cooperate with each other, improving the stability and reliability of the connection. During actual use, this can effectively prevent the wire end from detaching from the connector due to accidental touch or other reasons, providing strong guarantee for the assembly of the connector product. At the same time, when unlocking operation is required, the clasp can slide upward in the groove, making the separation of the secondary lock from the connector more convenient and improving the production assembly efficiency;

[0016] 2. By providing a horn buckle and a limiting groove, the chamfer design at the bottom of the horn buckle enables it to slide smoothly into the limiting groove and achieve a firm clamping with the connector. In product assembly, this structural design can effectively prevent the accidental separation of the secondary lock from the connector under the action of external force, ensuring the stable connection between the wire end and the plate end of the connector. Moreover, when unlocking operation is required, the special structure of the horn buckle can cooperate with the clasp, making the unlocking process smoother and improving the operation convenience;

[0017] 3. In summary, the secondary lock for preventing accidental touch of this horn connector, through the settings of structures such as grooves, moving slots, limiting slots, secondary locks, buckles and horn buckles, the cooperation between the grooves and the buckles ensures the tight connection between the secondary lock and the wire end, effectively preventing the wire end from detaching due to accidental touch. The moving slot provides space for the installation and movement of the wire end, making the assembly of the wire end more flexible. The combination of the limiting slot and the horn buckle further enhances the connection stability between the secondary lock and the connector, preventing loosening of the connection caused by external interference. Moreover, the cooperation between the horn buckle and the buckle can effectively prevent misoperation. When the secondary lock cannot be inserted into the connector, it indicates that the board end and the wire end of the connector are not assembled in place, and it can be intercepted in advance to prevent the unassembled products from flowing into the next stage.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Figure 1 - Figure 6

[0026] Please refer to Figure 1-6, in the embodiment of the present utility model, a secondary lock for preventing accidental touch of a horn connector includes: a connector 1, a secondary lock 2 is clamped above the left side of the connector 1. The connector 1 is composed of two front and rear board ends. Both the left and right ends of the connector 1 are provided with moving grooves 101, and wire ends 102 are arranged in the moving grooves 101. A base 201 is fixedly installed at the bottom of the secondary lock 2. The middle part of the secondary lock 2 is clamped on the wire end 102. The base 201 is clamped with the front and rear ends of the connector 1. Grooves 103 are opened at both the front and rear ends of the wire end 102, and limiting grooves 104 are opened at both the front and rear ends of the connector 1. The inside of the secondary lock 2 is clamped with the grooves 103, and the base 201 is clamped with the limiting grooves 104. The connector 1 is formed by welding the horn connector board ends to the front and rear ends of the PCB. During the combination process, moving grooves 101 are opened at both the left and right ends of the connector 1. Then, the wire ends 102 are loaded into the connector 1 and installed between the moving grooves 101. Before the wire ends 102 are loaded into the connector 1, grooves 103 are opened at both the front and rear ends thereof, and limiting grooves 104 are opened at the front and rear ends of the connector 1. The limiting grooves 104 are specifically opened outside the moving grooves 101. When the wire ends 102 are installed into the connector 1, the central axes of the limiting grooves 104 and the grooves 103 are in the same longitudinal position. Then, the secondary lock 2 is loaded from top to bottom. First, the inside of the secondary lock 2 passes through the grooves 103 of the wire ends 102 and slides down to be clamped with the grooves 103. Then, it slides down in the grooves 103 so that the bottom end of the base 201 is movably connected to the upper end of the connector 1. At this time, the lower part of the base 201 will slide into the limiting grooves 104 to be clamped with the connector 1, realizing the connection and limitation of the secondary lock 2 and the connector 1, preventing the phenomenon that the wire ends 102 are separated from the board ends of the connector 1 due to accidental touch of the horn plastic shell on the connector 1, and making the connection between the board ends of the connector 1 and the wire ends 102 more reliable; when the wire ends 102 and the board ends of the connector 1 are assembled, if the secondary lock 2 cannot be loaded into the board ends of the connector 1, it means that the board ends of the connector 1 and the wire ends 102 are not assembled in place, which can effectively prevent mistakes and prevent unassembled products from flowing into the next stage; when the base 201 slides to the upper part of the limiting grooves 104 of the connector 1, at this time, the wire ends 102 and the secondary lock 2 can be rotated to separate the board ends of the connector 1 and the wire ends 102. At this time, the secondary lock 2 is hung on the wire ends 102 and does not need to be reassembled, saving production and assembly time.

[0027] In the embodiment of the present utility model, buckles 202 are fixedly installed at both the front and rear ends of the inner wall of the secondary lock 2. The buckles 202 are arranged in a matching manner with the grooves 103, and the bottom of the buckle 202 is chamfered. The buckle 202 slides into the groove 103 through the bottom chamfer and is clamped with the wire end 102. Buckles 202 are fixedly installed at both the front and rear ends of the inner wall of the secondary lock 2. The buckles 202 are arranged in a matching manner with the grooves 103 at the front and rear ends of the wire end 102. The buckle 202 can slide into the groove 103, and the two cooperate with each other. Moreover, the bottom of the buckle 202 is chamfered, so that the buckle 202 can slide into the groove 103 more smoothly through the bottom chamfer, and then is clamped with the wire end 102. When the base 201 and the connector 1 are loosened, the secondary lock 2 can be unlocked from the connector 1 by sliding the buckle 202 upward in the groove 103.

[0028] In the embodiment of the present utility model, a cowhorn buckle 203 is fixedly installed at the bottom of the base 201. The cowhorn buckle 203 is arranged in a matching manner with the limiting groove 104, and the bottom of the cowhorn buckle 203 is chamfered. The cowhorn buckle 203 slides into the limiting groove 104 through the bottom chamfer and is clamped with the connector 1. Cowhorn buckles 203 are fixedly installed on both the front and rear sides of the bottom of the base 201, and the cowhorn buckles 203 are arranged in a matching manner with the limiting groove 104. Since the bottom of the cowhorn buckle 203 is chamfered, the cowhorn buckle 203 can slide into the limiting groove 104 more smoothly by virtue of the bottom chamfer, so as to be clamped with the connector 1. When the cowhorn buckle 203 disengages from the limiting groove 104, the wire end 102 can be driven to rotate outward in the moving groove 101 by the clamping of the buckle 202 and the wire end 102, realizing the unlocking of the wire end 102 and the connector 1.

[0029] Working principle: First, the connector 1 is composed of the front and rear ends of the horn connector 1 board end welded on the PCB. During the combination process, moving slots 101 are opened at both the left and right ends of the connector 1. Then, before the wire end 102 is inserted into the connector 1, grooves 103 are opened at the front and rear ends of the wire end 102, and limiting slots 104 are opened at the corresponding positions at the front and rear ends of the connector 1. The limiting slots 104 are specifically opened outside the moving slots 101. When the wire end 102 is installed inside the connector 1, the central axes of the limiting slots 104 and the grooves 103 are in the same longitudinal position. Then, the secondary lock 2 is inserted from top to bottom. First, the inside of the secondary lock 2 passes through the groove 103 of the wire end 102 and slides down. At this time, the buckle 202 inside the secondary lock 2 can smoothly slide into the groove 103 through the bottom chamfer due to the chamfer at its bottom, achieving a snap connection with the wire end 102. Continuing to slide down makes the bottom end of the base 201 movably connected to the upper end of the connector 1. At the same time, the horn buckle 203 below the base 201 slides into the limiting slot 104 through the bottom chamfer and is snap-connected to the connector 1, realizing the connection and limitation between the secondary lock 2 and the connector 1. When it is necessary to unlock the connector 1 and the secondary lock 2, when the horn buckle 203 disengages from the limiting slot 104, the base 201 and the connector 1 are loosened, and the secondary lock 2 can slide upward in the groove 103 through the buckle 202 to unlock the secondary lock 2 and the connector 1; when the horn buckle 203 disengages from the limiting slot 104, the wire end 102 can be driven to rotate outward in the moving slot 101 through the snap connection between the buckle 202 and the wire end 102, realizing further unlocking of the wire end 102 and the connector 1. And at this time, the secondary lock 2 is hung on the wire end 102, eliminating the need for re-assembly and saving production and assembly time.
