DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a flip-type electrical connector proposed in one embodiment of the utility model includes a base 1, and a flip-cover body 2 rotatably connected to the base 1, a slot 8 is provided on one side of the base 1, a plurality of elastic terminals 7 are provided at the slot 8 of the base 1, and a pressure block 3 is fixedly connected to one side of the flip-cover body 2 corresponding to the elastic terminal 7, two symmetrically distributed special-shaped positioning blocks 4 are fixedly connected to the flip-cover body 2 on both sides of the pressure block 3, a clearance cavity groove 5 is provided at the base 1 corresponding to the special-shaped positioning block 4, and a through hole is provided at the clearance cavity groove 5 of the base 1, and a locking rod 6 for positioning the special-shaped positioning block 4 is slidably connected to the through hole of the base 1.

[0023] It should be noted that when in use, the external wiring board is inserted into the slot 8, and the flip cover body 2 is rotated so that the pressure block 3 is abutted against the elastic terminal 7, and then the elastic terminal 7 is in contact with the wiring board to form an electrical connection. By fixing two special-shaped positioning blocks 4 on one side of the flip cover body 2, when the flip cover body 2 is rotated, the special-shaped positioning block 4 can be closed to the make way cavity 5 of the base 1, and the locking rod 6 is slidably connected at the through hole of the base 1. The locking rod 6 can extend to the special-shaped positioning block 4 to achieve locking and positioning of the special-shaped positioning block 4, and then the flip cover body 2 is fixed to ensure the connection stability of the wiring board and avoid poor circuit contact.

[0024] like Figure 3 As shown, in some embodiments, a second spring 19 is fixedly connected to the connection between one end of the locking rod 6 and the base 1 , and the other end of the locking rod 6 is integrally formed with an arc-shaped end 20 .

[0025] It should be noted that the provision of the second spring 19 can achieve the extension and resetting of the locking rod 6 , and the provision of the arc-shaped end 20 can facilitate the insertion of the locking rod 6 into the special-shaped positioning block 4 .

[0026] like Figure 2 As shown, in some embodiments, the special-shaped positioning block 4 includes an arc-shaped block body 9 fixedly connected to the flip cover body 2, and an arc protrusion 11 integrally formed on one side of the arc-shaped block body 9, and a locking hole 10 adapted to the locking rod 6 is opened on the arc-shaped block body 9.

[0027] It should be noted that the arc radius of the arc protrusion 11 is smaller than the arc block body 9. When the flip cover body 2 rotates, the arc protrusion 11 first contacts the arc end 20 at the end of the locking rod 6, and then drives the locking rod 6 to close into the through hole of the base 1. When the flip cover body 2 is completely closed with the base 1, the locking hole 10 corresponds to the locking rod 6, and then the locking rod 6 is stretched under the action of the second spring 19 and enters the locking hole 10 of the arc block body 9, thereby realizing the locking and positioning of the special-shaped positioning block 4, and then fixing the flip cover body 2.

[0028] like Figure 2 As shown, in some embodiments, a cavity 12 penetrating to the locking hole 10 is provided on the flip cover body 2 and the arc block body 9, and a wedge block 13 is slidably connected to the cavity 12 of the flip cover body 2 and the arc block body 9, and the wedge block 13 can drive the locking rod 6 to leave the locking hole 10 when it moves.

[0029] It should be noted that, by opening a cavity 12 on the flip cover body 2 and the arc block body 9, and slidingly connecting a wedge block 13 at the cavity 12, the wedge surface of the wedge block 13 corresponds to the locking rod 6, and the positioning function of the flip cover body 2 needs to be cancelled. Then, when taking out the wiring board, it is only necessary to control the wedge block 13 to slide toward the locking hole 10, and the wedge surface of the wedge block 13 contacts the arc end 20 at the end of the locking rod 6, and then the locking rod 6 leaves the locking hole 10, canceling the locking function of the special-shaped positioning block 4 and the flip cover body 2, and rotating the flip cover body 2.

[0030] like Figure 2 As shown, in some embodiments, a circular hole 15 penetrating into the cavity 12 is provided on the flip cover body 2, and a telescopic rod 14 is slidably connected to the circular hole 15 of the flip cover body 2, one end of the telescopic rod 14 is connected and fixed to the wedge block 13, and the other end of the telescopic rod 14 extends to the outside of the flip cover body 2 and is fixed with a protective cap 17, and a first spring 16 is sleeved on the telescopic rod 14, and the two ends of the first spring 16 are respectively against the protective cap 17 and the flip cover body 2.

[0031] It should be noted that, by opening a circular hole 15 that penetrates the cavity 12 on the flip cover body 2, and slidingly connecting the telescopic rod 14 at the circular hole 15, the telescopic rod 14 can control the movement of the wedge block 13 when it is extended or retracted, and then control the locking state of the special-shaped positioning block 4. By setting the first spring 16, the setting of the first spring 16 can realize the automatic resetting of the telescopic rod 14 and the wedge block 13.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments, a pressing plate 18 is fixed on the protective caps 17 corresponding to the two special-shaped positioning blocks 4 .

[0033] It should be noted that by fixing the pressing plate 18 between the two protective caps 17, the positioning function of the flip cover body 2 is eliminated. Then, when taking out the cable tray, it is only necessary to press down the pressing plate 18, while controlling the movement of the two locking rods 6, which is very convenient.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
