Description

Technical Field

[0001] The utility model relates to the technical field of vehicle connectors, in particular to an assembled inspection plug-in connector male head. Background Art

[0002] With the rapid advancement of modern science and technology, electricity has become an indispensable resource in our daily lives and work, especially when it comes to powering outdoor electrical and electronic equipment. To ensure a stable and secure power supply in diverse and changing environments, human ingenuity has spawned a wide variety of connector designs. These connectors serve as bridges for power transmission, carrying both current and signals and serving as the cornerstone for ensuring the proper functioning of equipment.

[0003] However, traditional connectors usually have multiple conductive terminals embedded in an insulating body to achieve plug-in and unplugging of multiple conductive lines. However, since the conductive terminals are all slender pin structures, it is very easy for the pins to bend during the plugging process of the male and female sockets, resulting in problems such as improper plugging or poor conductive parts, which are obvious defects. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an assembled inspection plug-in connector male head which effectively increases the conductive contact area, improves the connector assembly efficiency and structural reliability.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: an assembled inspection plug-in connector, comprising an insulating colloid, a plurality of plug-in slots arranged in parallel on the insulating colloid, and an electrical terminal installed in the plug-in slot for fixedly connecting to the wire. The top of the insulating colloid is provided with a snap-on lock hook, and the middle part of the electrical terminal extends downward to form a widened body. The front end of the widened body is provided with two elastic conductive sheets close to each other, and the rear end of the widened body is provided with a wiring terminal with an upper and lower width smaller than the widened body, and the wiring terminal is fixedly connected to the wire; the upper and lower widths of the rear end of the plug-in slot are greater than the upper and lower widths of the widened body, and the insulating colloid is horizontally provided with a first through hole that passes through the plurality of plug-in slots, and the first through hole is embedded with an anti-slip pin that abuts against the rear end of the widened body.

[0006] Preferably, the side wall of the anti-slip pin is provided with a raised snap-fit ​​block, and the inner wall of the first through hole begins to have a snap-fit ​​groove corresponding to the snap-fit ​​block. When the anti-slip pin is inserted into the first through hole, the snap-fit ​​block is embedded in the snap-fit ​​groove.

[0007] Preferably, an elastic lock is obliquely provided on the lower side of the widened body, and a second through hole penetrating through the plurality of plug-in slots is transversely opened in the insulating colloid, and the end of the elastic lock abuts against the inner wall of the second through hole.

[0008] Preferably, the front ends of the two elastic conductive sheets located on the same electrical terminal are bent outward to form a trumpet-mouth structure.

[0009] Preferably, the widened body, the terminal and the elastic conductive sheet are formed by bending a conductive metal sheet multiple times.

[0010] Preferably, the left and right inner walls of the front portion of the plug slot are each provided with an accommodating cavity for accommodating two elastic conductive sheets respectively.

[0011] The beneficial effect of the present invention is that: the present invention provides an assembled inspection plug-in connecting male head. During the assembly process of the connecting male head, the wire is first fixedly connected to the terminal on the electrical terminal, and then the electrical terminal is vertically inserted into the plug-in slot. After all the electrical terminals are fully inserted into the plug-in slot, the anti-slip pin is inserted from the first through hole. Since the anti-slip pin abuts against the rear end of the widened body in each electrical terminal, the electrical terminal is effectively prevented from loosening from the plug-in slot. The invention is easy to assemble and has high tensile strength. The widened design of the elastic conductive sheet has a larger cross-sectional area for current flow during electrical connection and a higher conductivity. The structural reliability is significantly improved and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to the embodiments. The contents mentioned in the embodiments are not intended to limit the present invention.

[0018] like Figures 1 to 5As shown, an assembled inspection plug-in connector male head includes an insulating colloid 1, a plurality of plug-in slots 11 arranged in parallel on the insulating colloid 1, and an electrical terminal 2 installed in the plug-in slot 11 for fixedly connecting to a wire. A snap-on lock hook 12 is provided on the top of the insulating colloid 1, and the middle part of the electrical terminal 2 extends downward to form a widened body 21. The front end of the widened body 21 is provided with two elastic conductive sheets 22 close to each other. The widened elastic conductive sheets 22 have a larger cross-sectional area for electrical connection and a higher conductivity. The rear end of the widened body 21 is provided with a wiring terminal 23 with an upper and lower width smaller than the widened body 21, and the wiring terminal 23 is fixedly connected to the wire; the upper and lower widths of the rear end of the plug-in slot 11 are greater than the upper and lower widths of the widened body 21. The insulating colloid 1 is laterally provided with a first through hole 13 that passes through the plurality of plug-in slots 11, and the first through hole 13 is embedded with an anti-drop pin 3 that abuts against the rear end of the widened body 21.

[0019] During the assembly process of the connecting male plug, the wire is first fixedly connected to the terminal 23 on the electrical terminal 2, and then the electrical terminal 2 is vertically inserted into the plug-in slot 11. After all the electrical terminals 2 are fully inserted into the plug-in slot 11, the anti-slip pin 3 is inserted from the first through hole 13. Since the anti-slip pin 3 abuts against the rear end of the widened body 21 in each electrical terminal 2, the electrical terminal 2 is effectively prevented from loosening from the plug-in slot 11. The assembly is convenient, the tensile strength is high, the structural reliability is significantly improved, and the practicality is strong.

[0020] In this embodiment, the sidewall of the anti-dropout pin 3 is provided with a raised snap-in block 31, and the inner wall of the first through hole 13 begins to have a snap-in groove corresponding to the snap-in block 31. When the anti-dropout pin 3 is inserted into the first through hole 13, the snap-in block 31 engages with the snap-in groove. The design of the snap-in block 31 and the snap-in groove effectively prevents the anti-dropout pin 3 from escaping from the first through hole 13, further improving the reliability of the anti-dropout pin 3 and enhancing the structural stability.

[0021] In this embodiment, a resilient latch 24 is provided at an angle on the lower side of the widened body 21. The insulating colloid 1 is transversely formed with a second through hole 14 extending through the plurality of insertion slots 11. The distal end of the resilient latch 24 abuts against the inner wall of the second through hole 14. During the assembly process of sequentially inserting the plurality of electrical terminals 2 into the insertion slots 11, when the widened body 21 is properly inserted, the resilient latch 24 pops downward and abuts against the inner wall of the second through hole 14, completing the first locking operation. This prevents the electrical terminal 2 inserted before the anti-drop pin 3 is inserted from coming loose, effectively preventing the previous electrical terminal 2 from becoming loose when the next electrical terminal 2 is inserted, thereby improving assembly efficiency.

[0022] In this embodiment, the front ends of the two elastic conductive sheets 22 located on the same electrical terminal 2 are bent outward to form a bell-mouth structure. During the plugging process of the male connector and the female connector, the bell-mouth structure is more conducive to the electrical connector in the female connector sliding into the gap between the two elastic conductive sheets 22, effectively avoiding the electrical connector and the electrical connector from resisting each other and deforming, or even causing poor conductivity, and improving reliability.

[0023] In this embodiment, the widened body 21, the terminal 23 and the elastic conductive sheet 22 are formed by bending a conductive metal sheet multiple times, which effectively reduces the manufacturing difficulty and production cost of the electrical terminal 2, and the integrated structure has higher production efficiency.

[0024] In this embodiment, the left and right inner walls of the front part of the plug-in slot 11 are provided with accommodating cavities 15 for respectively accommodating two elastic conductive sheets 22. When the electrical connector is inserted into the gap between the two elastic conductive sheets 22, the setting of the accommodating cavity 15 provides deformation space for the elastic conductive sheet 22, thereby avoiding the problem that the electrical connector in the female socket is difficult to insert into the gap between the two elastic conductive sheets 22, making plugging and unplugging smoother and more convenient to use.
