Description

Technical Field

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

[0002] Connectors are also called connectors. In China, they are also called joints and sockets. They generally refer to electrical connectors. They are devices that connect two active devices and transmit current or signals. The male and female ends can transmit information or current after contact, and are also called connectors.

[0003] Connectors generally have multiple terminals, which usually need to be welded to cables. To facilitate welding, the wire cores of the cable welds are spread out in a fan shape. If the scattered wire cores are not restrained after welding, the wire cores will loosen, making it easy to tear the welding position between the terminal and the wire core. To solve this problem, some connectors on the market use wire clamps or wire holders to solve this problem, but this will increase costs.

[0036] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0037] Please refer to Figures 1 to 5 As shown, it shows the specific structure of a preferred embodiment of the utility model, which is a female connector.

[0038] The structure of the first grounding portion 61 and the first connecting portion 71 forms a wiring channel 63, which can limit the fan-shaped wire cores to prevent them from loosening and breaking. At the same time, the cable is tightened by the wiring channel 63, so that the entire cable is completely fixed and will not loosen.

[0039] Please refer to Figure 1-3As shown, the present application provides a female connector, including a first terminal module 10 and a second terminal module 20; the first connecting column 11 on the first terminal module 10 is inserted into the first connecting hole 21 on the second terminal module 20, and the second connecting column 22 on the second terminal module 20 is inserted into the second connecting hole 12 on the first terminal module 10; the insulating sheet 30 is sandwiched between the first terminal module 10 and the second terminal module 20, and part of the first connecting column 11 and the second connecting column 22 passes through the insulating sheet 30. The first terminal module 10 and the second terminal module 20 are injection molded parts, and the insulating sheet 30 is sandwiched between the first terminal module 10 and the second terminal module 20. Then the first terminal module 10 and the second terminal module 20 are assembled together, and part of the first connecting column 11 and the second connecting column 22 passes through the insulating sheet 30, so that the insulating sheet 30 can be well limited and prevented from loosening.

[0040] The first insulating body 40 is injection molded together with the first terminal module 10 and the second terminal module 20; the first shielding shell 50 is wrapped in the first insulating body 40, and the first tongue portion 41 of the first insulating body 40 is suspended in the first shielding shell 50. After the first insulating body 40 is injection molded together with the first terminal module 10 and the second terminal module 20, the grounding ears 31 on the left and right sides of the insulating sheet 30 are exposed on the left and right sides of the first insulating body 40, and are in contact and conduction with the first shielding shell 50. In this way, the first shielding shell 50, the second shielding shell 60, and the third shielding shell 70 are connected together, and the grounding pin 62 can share the grounding pin 62, and the structure is ingenious.

[0041] The second shielding shell 60 and the third shielding shell 70 wrap the first base portion 43 of the first insulating body 40, and the rear of the first terminal module 10 and the second terminal module 20. The first shielding shell 50 wraps the first tongue portion 41 of the first insulating body 40, so that the front half of the first terminal 14 and the second terminal 24 are well shielded and protected. After the second shielding shell 60 and the third shielding shell 70 are buckled together, under the joint action of the second shielding shell 60 and the third shielding shell 70, the rear half of the first terminal 14 and the second terminal 24, as well as the fan-shaped distributed wire cores are well shielded and protected. The first shielding shell 50, the second shielding shell 60, and the third shielding shell 70 overlap partially on the first base portion 43 of the first insulating body 40, which not only ensures the firmness of the connection, but also ensures the overall shielding performance.

[0042] The rear of the second shielding shell 60 is provided with an arc-shaped first grounding portion 61, and the first grounding portion 61 is provided with a grounding pin 62; the rear of the third shielding shell 70 is provided with a first connecting portion 71; part of the first connecting portion 71 is connected to the first grounding portion 61; and a wiring channel 63 is formed between the first grounding portion 61 and the first connecting portion 71. In this embodiment, the first connecting portion 71 has three pieces, wherein the left and right first connecting portions 71 are welded together with the first grounding portion 61. The elastic first grounding portion 61 and the first connecting portion 71 together form the wiring channel 63. After the welding of the wire core of the cable with the pins of the first terminal 14 and the second terminal 24 is completed, the wiring channel 63 will tighten the cable, so that the cable can be fixed without the aid of other components, preventing the wire core and the first terminal 14 and the second terminal 24 from being torn off at the welding position, facilitating the subsequent process and saving costs. Preferably, the first grounding portion 61 and the first grounding portion 61 are spot welded together, and the first connecting portion 71 also has a certain curvature. The first shielding shell 50 , the second shielding shell 60 , and the third shielding shell 70 can share a grounding pin 62 for grounding, and the structure is simple.

[0043] The housing 80 includes a first shell 810 and a second shell 820, wherein the first shell 810 and the second shell 820 enclose the first shielding shell 50, the second shielding shell 60, and the third shielding shell 70; a wiring hole 81 is provided on the back of the housing 80 to communicate with the wiring channel 63. The cable passes through the wiring channel 63 and the wiring hole 81; after the first shell 810 and the second shell 820 are buckled together, the wiring hole 81 will tighten the cable, so that the cable is fixed for the second time and the cable will be more secure.

[0044] Preferably, the first terminal module 10 includes a second insulating body 13 and a plurality of first terminals 14; the second insulating body 13 and the first terminals 14 are combined together by injection molding; the second terminal module 20 includes a third insulating body 23 and a plurality of second terminals 24; the third insulating body 23 and the second terminals 24 are combined together by injection molding; the rear sections of the first terminals 14 and the second terminals 24 are widened. The widening of the rear sections of the first terminals 14 and the second terminals 24 is conducive to improving the electrical conductivity of the terminals.

[0045] Preferably, the connecting ends of the first terminal 14 and the second terminal 24 are bent toward one side of the insulating sheet 30. That is, the contact ends of the first terminal 14 and the second terminal 24 are bent toward the insulating sheet 30 at a certain angle, which can effectively prevent the contact ends of the first terminal 14 and the second terminal 24 from warping (preventing pin warping), so that the connector has a longer service life and better quality.

[0046] Preferably, the left side, right side and front end of the insulating sheet 30 are embedded in the limiting groove 44 inside the first insulating body 40. When the first terminal module 10, the second terminal module 20 and the insulating sheet 30 are assembled together, the three are combined with the first insulating body 40 by injection molding. Under the action of the insulating sheet 30, this design makes the first terminal module 10, the second terminal module 20 and the first insulating body 40 more firmly combined, and is also conducive to positioning the first terminal module 10 and the second terminal module 20, and the processing is more convenient and accurate.

The first shielding shell 50 is inserted into the front position of the first insulating body 40, and the first buckling hole 52 on the first buckling portion 51 is buckled in the first buckling portion 51, so that the front half of the first terminal 14 and the second terminal 24 are well shielded and protected. The first buckling portion 51 of this embodiment has two divisions at the rear of the upper and lower walls of the first shielding shell 50. Correspondingly, there are also two first buckling blocks 42, which are respectively distributed at the top and bottom of the first insulating body 40.

[0048] Preferably, the left and right walls of the second shielding shell 60 are torn with a second buckling portion 64; the left and right walls of the third shielding shell 70 are torn with a second buckling hole 72; the second buckling portion 64 is buckled in the second buckling hole 72. The front of the second shielding shell 60 is provided with a first limiting portion 65, the first limiting portion 65 blocks the front of the first base portion 43, and the side wall of the second shielding shell 60 is protruding inwardly with a second limiting portion 66, the second limiting portion 66 blocks the rear of the first base portion 43. When the second shielding shell 60 and the third shielding shell 70 are buckled together, the second buckling portion 64 is buckled in the second buckling hole 72, the second limiting portion 66 protruding inwardly from the side wall of the second shielding shell 60 blocks the rear of the first base portion 43 of the first insulating body 40, and the first limiting portion 65 bent at the front of the second shielding shell 60 blocks the front of the first base portion 43, so that the first insulating body 40 is firmly fixed by the first shielding shell 50, the second shielding shell 60, and the third shielding shell 70, and will not loosen. This assembly method has a simple structure and is more efficient in assembly.

[0049] Preferably, the first shell 810 is provided with a third snap-fitting portion 811, which is snapped on the third snap-fitting block 821 of the second shell 820; the second shell 820 is provided with a fourth snap-fitting portion 822, which is snapped on the fourth snap-fitting block 812 of the first shell 810. When the first shell 810 and the second shell 820 are snapped together, the third snap-fitting portion 811 is snapped on the third snap-fitting block 821; the fourth snap-fitting portion 822 is snapped on the fourth snap-fitting block 812, and this design makes the assembly of the housing 80 very convenient and efficient. In this embodiment, the structures of the third snap-fitting portion 811 and the fourth snap-fitting portion 822 are preferably barbs.

[0050] The shell 80 is provided with an interlocking groove 83 inside; the first shielding shell 50, the second shielding shell 60, and the second shielding shell 60 are embedded in the interlocking groove 83; the front part of the first shielding shell 50 is provided with a third limiting portion 53, and the third limiting portion 53 is embedded in the limiting notch 82 on the shell 80. The interlocking groove 83 can limit the position of the first shielding shell 50, the second shielding shell 60, and the second shielding shell 60 to prevent them from moving forward and backward. At the same time, the front part of the first shielding shell 50 is provided with a third limiting portion 53 embedded in the limiting notch 82 on the shell 80, which further improves the assembly firmness between the shell and the first shielding shell 50, the second shielding shell 60, and the second shielding shell 60.

[0051] The assembly steps of the female connector are as follows: 1. First, clamp the insulating sheet 30 between the first terminal module 10 and the second terminal module 20. 2. Extrude the first terminal module 10 and the second terminal module 20 so that the two are assembled into a whole. 3. The first insulating body 40 and the first terminal module 10 and the second terminal module 20 are injection molded into a whole in an injection molding machine. 4. The first shielding shell 50 is buckled on the first insulating body 40 and pressed. 5. The second shielding shell 60 and the third shielding shell 70 are buckled to wrap the first base portion 43 of the first insulating body 40, and partially overlap with the first shielding shell 50. 6. The first shell 810 and the second shell 820 are buckled to wrap the first shielding shell 50, the second shielding shell 60, and the third shielding shell 70.

[0052] In summary, the design focus of the utility model is that the insulating sheet 30 separates the first terminal module 10 and the second terminal module 20, and the first shielding shell 50, the second shielding shell 60, and the third shielding shell 70 wrap the first terminal module 10 and the second terminal module 20, so that the entire female connector has a better shielding effect. After the cable welding is completed, the wiring channel 63 formed by the first connecting part 71 and the first grounding part 61 tightens the cable. This design cleverly utilizes the structure of the first shielding shell 50, the second shielding shell 60, and the third shielding shell 70 to prevent the fan-shaped distributed wire core from loosening, saving costs. In addition, the wiring hole 81 of the outer shell 80 can further tighten the cable, and the anti-loosening effect is better.
