Description

Technical Field

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

[0002] An electronic connector is also often referred to as a circuit connector. The electrical connector bridges two conductors on a loop, enabling current or signals to flow from one conductor to another. It is a conductor device used to complete the electrical connection between circuits or electronic machines, etc. The component that serves as a bridge between the two is called a connector. Among them, the Type-C connector is the most prominent.

[0003] Type-C electronic connectors are widely used in terminals such as computers, mobile phones, and charging devices. Similarly, Type-C data cables can also be used for power banks to charge electronic devices. Type-C electronic connectors are divided into male and female sockets, which are respectively used to be fixed on electronic devices or plugged into electronic devices. One end of the terminal of the Type-C electronic connector is electrically connected to the power bank plug, and the other end is electrically connected to the circuit board inside the electronic device.

[0004] Due to the portable nature of the power bank, during mobile use, the connection part of the Type-C electronic connector may come into contact with liquid. Since the crimp connection strength between the male connection socket and the female connection socket is relatively low, it is easy to be pulled apart, and the liquid is likely to seep in from the gap between the plug and the socket, resulting in damage and short circuit. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a Type-C electronic connector to solve the technical problem of the relatively low crimp connection strength of the electronic connector in the prior art.

[0006] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0007] A Type-C electronic connector includes a fixing groove and a plugging female socket. The fixing groove is opened at one end of the power bank. The plugging female socket is arranged inside the fixing groove, and the end part located inside the power bank is connected to the circuit board. A circuit board is fixedly connected inside the plugging female socket. It further includes:

[0008] A housing, one end of the housing is connected with a plugging male socket, and the other end is connected with a lead wire. The plugging male socket is plugged and connected with the circuit board;

[0009] A sleeve is fixedly connected to the outer edge of the fixing groove at the end of the power bank. One end of the outer shell close to the male plug is inserted into the inner side of the sleeve. A horn-shaped groove is opened on the inner side of one end of the sleeve close to the outer shell, and an inclined groove corresponding to the horn-shaped groove is opened on the outer shell. A waterproof ring is arranged at the connection between the horn-shaped groove and the inclined groove.

[0010] A clamping structure is provided with two groups, which are respectively connected to both sides of the outer shell in a matching manner, and the clamping structures are all arranged between the outer shell and the sleeve.

[0011] As a further solution of the present utility model: each clamping structure includes a clamping rod and a clamping groove. One side of the clamping rod close to the outer shell is connected with a hinge seat. The clamping rod is rotatably connected to the corresponding side of the outer shell through the hinge seat. One end of the clamping rod is connected with a clamping block, and the other end is connected with a pressing plate. The clamping groove is opened at a position on the outer side of the sleeve aligned with the clamping block. The clamping block is clamped with the clamping groove, and a spring is connected between one end of the clamping rod close to the clamping block and the outer shell.

[0012] As a further solution of the present utility model: the clamping block is a right-angled trapezoid, the hypotenuse of the clamping block is located on the side close to the clamping groove, and the long right-angled side of the clamping block is clamped with the clamping groove.

[0013] As a further solution of the present utility model: an inclined sliding groove is opened at one end of the outer side of the sleeve close to the outer shell, and the hypotenuse of the clamping block is slidably matched with the sliding groove.

[0014] As a further solution of the present utility model: an anti-slip protrusion is arranged on the side of each pressing plate away from the outer shell. As a further solution of the present utility model: a water-absorbing sponge is connected in a matching manner at one end of the inclined groove and the hypotenuse close to the male plug 4.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. The female plug and the male plug of the present utility model are connected by plugging and unplugging through the sleeve and the outer shell, and a waterproof ring is arranged between the outer shell and the sleeve. When the outer shell and the sleeve squeeze the waterproof ring, the electronic connector has waterproof performance. In addition, the female plug and the male plug are connected by clamping through the clamping block and the clamping groove, effectively ensuring the stability of the connection between the female plug and the male plug and avoiding natural loosening.

[0017] 2. The present utility model is provided with an inclined sliding groove at one end of the outer side of the sleeve close to the outer shell. Also, because the clamping block is a right-angled trapezoid, when the outer shell and the sleeve are inserted, the hypotenuse of the clamping block slides into the clamping groove along the sliding groove. The sliding groove provides a space for the clamping block to slide to avoid jamming, so that the outer shell can be directly inserted into the sleeve, avoiding the need to press the pressing plate during insertion.

Specific embodiments

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1 - 5 shown, a Type-C electronic connector includes a fixing groove and a female plug connector 2. The female plug connector 2 is the female seat of the Type-C connector. The fixing groove is opened at one end of the power bank 1. The female plug connector 2 is arranged inside the fixing groove, and the end part located inside the power bank 1 is electrically connected to the circuit board. A circuit board 3 is fixedly connected inside the female plug connector 2. The connector further includes an outer shell 5, a sleeve 7 and a clamping structure;

[0027] One end of the outer shell 5 is connected with a male plug connector 4. The male plug connector 4 is the male seat of the Type-C connector. The other end is connected with a lead wire 6. Specifically, the outer shell 5 and the male plug connector 4 are integrally formed by injection molding. The male plug connector 4 is plugged and connected with the circuit board 3. When the male plug connector 4 is plugged in place with the circuit board 3 inside the female plug connector 2, electrical connection can be achieved;

[0028] The sleeve 7 is fixedly connected to the outer side of the edge of the fixed slot at the end of the power bank 1. One end of the outer shell 5 close to the male plug 4 is inserted into the inner side of the sleeve 7. A horn-shaped groove 8 is formed on the inner side of one end of the sleeve 7 close to the outer shell 5. Then, the inner side of one end of the sleeve 7 close to the outer shell 5 is in a flared shape, which enables the outer shell 5 to be inserted into the sleeve 7 to achieve blind insertion. Moreover, an inclined groove corresponding to the horn-shaped groove 8 is formed on the outer shell 5. A waterproof ring 9 is arranged at the joint of the horn-shaped groove 8 and the inclined groove. When the outer shell 5 is inserted and connected to the sleeve 7, the inclined groove and the horn-shaped groove 8 squeeze the waterproof ring 9, thereby achieving sealing and waterproofing.

[0029] There are two sets of clamping structures, which are respectively connected to both sides of the outer shell 5 in a matching manner. The clamping structures are all arranged between the outer shell 5 and the sleeve 7 and are used to connect the outer shell 5 and the sleeve 7.

[0030] When the male plug 4 is connected to the circuit board 3 in place, the sleeve 7 is sleeved on the outer side of one end of the outer shell 5 close to the male plug 4. The clamping structure provides a tight fitting force between the outer shell 5 and the sleeve 7, avoiding natural loosening between the circuit board 3 and the male plug 4 and being not easily pulled apart. The waterproof ring 9 is fixed on the horn-shaped groove 8. When the outer shell 5 is inserted into the sleeve 7, the inclined groove and the horn-shaped groove 8 squeeze the waterproof ring 9. Also, because a clamping structure is arranged between the outer shell 5 and the sleeve 7, the sealing performance between the sleeve 7 and the outer shell 5 is effectively ensured, and the waterproof performance during use is improved.

[0031] In some specific implementation schemes, such as Figure 3 or Figure 4 As shown, in order to facilitate increasing the connection stability between the outer shell 5 and the sleeve 7, each set of clamping structures includes a clamping rod 11 and a clamping groove 13. A hinge seat is connected to one side of the clamping rod 11 close to the outer shell 5. The clamping rod 11 is rotatably connected to the corresponding side of the outer shell 5 through the hinge seat. One end of the clamping rod 11 is connected with a clamping block 12, and the other end is connected with a pressing plate 16. The end of the power bank 1 inclines away from the outer shell 5, which is convenient for the clamping block 12 end to be lifted when pressing the pressing plate 16. The clamping groove 13 is opened at the position on the outer side of the sleeve 7 aligned with the clamping block 12. The clamping block 12 is clamped with the clamping groove 13. A spring 14 is connected between one end of the clamping rod 11 close to the clamping block 12 and the outer shell 5. The spring 14 is located at the position between the clamping block 12 and the hinge seat. The clamping structure is used to connect the outer shell 5 and the sleeve 7. While the sleeve 7 and the outer shell 5 are inserted, the waterproof ring 9 between them is squeezed, which can enhance the waterproofness at the connection and prevent water stains from infiltrating from the connection, thus avoiding short circuit and damaging the components.

[0032] In some specific implementation schemes, such as Figure 4 As shown, in order to prevent the clamping block 12 from being stuck with the end of the sleeve 7 during direct insertion, the clamping block 12 is a right trapezoid, and the hypotenuse of the clamping block 12 is located on the side close to the clamping groove 13. The long right-angled side of the clamping block 12 is clamped with the clamping groove 13.

[0033] In some specific implementation schemes, such asFigure 4 As shown, in order to further enhance the smoothness of the engagement between the clamping block 12 and the clamping groove 13, an inclined chute 15 is formed at one end of the outer side of the sleeve 7 close to the housing 5, and the hypotenuse of the clamping block 12 is in sliding fit with the chute 15.

[0034] When the female socket 2 is connected to the male socket 4 and the housing 5 is inserted into the sleeve 7, after the chute 15 contacts the hypotenuse of the clamping block 12, due to the applied extrusion force, the clamping block 12 elastically deforms along the hinge point of the clamping rod 11 to create a clearance space for the clamping block 12 to enter and exit the clamping groove 13. At this time, the spring 14 is stretched, and then the clamping block 12 enters the clamping groove 13, and then automatically resets under the elastic restoring force of the spring 14 to clamp the clamping block 12 in the clamping groove 13, realizing the clamping connection between the female socket 2 and the male socket 4. When it is necessary to separate the female socket 2 from the male socket 4, under the action of pressing the pressing plate 16, the clamping rod 11 rotates, the spring 14 is stretched, the clamping block 12 disengages from the clamping groove 13, and the housing 5 is pulled out towards the end away from the sleeve 7 to realize the separation between the female socket 2 and the male socket 4.

[0035] In some specific embodiments, as Figure 5 shown, in order to prevent the fingers from slipping when pressing the pressing plate 16, an anti-slip protrusion 17 is provided on the side of each pressing plate 16 away from the housing 5.

[0036] In some specific embodiments, as Figure 4 shown, in order to further enhance the waterproof property of the connection part, a water-absorbing sponge 10 is connected in cooperation between the fitting part of the inclined groove and the hypotenuse near one end of the male socket 4. The water-absorbing sponge 10 has water absorption property. When the housing 5 is separated from the sleeve 7, the water-absorbing sponge 10 can prevent the water stains clamped between the two from entering the female socket 2.

[0037] For the convenience of those skilled in the art to understand the embodiments of this solution, the working principle of this solution will be briefly described below in combination with a specific application scenario:

[0038] When the female socket 2 is connected to the male socket 4 so that the housing 5 is inserted into the sleeve 7, after the chute 15 contacts the hypotenuse of the latch 12, due to the applied extrusion force, the latch 12 elastically deforms along the hinge point of the latch rod 11 to create a clearance space for the latch 12 to enter and exit the card slot 13. At this time, the spring 14 is stretched, and then the latch 12 enters the card slot 13. Then, under the elastic restoring force of the spring 14, it automatically resets to latch the latch 12 in the card slot 13, realizing the snap connection between the female socket 2 and the male socket 4. Since a waterproof ring 9 is provided at the joint between the horn groove 8 and the inclined groove, when the housing 5 and the sleeve 7 are inserted and connected, the inclined groove and the horn groove 8 squeeze the waterproof ring 9, so that sealing and waterproofing can be achieved. When it is necessary to separate the female socket 2 from the male socket 4, under the action of pressing the pressing plate 16, the latch rod 11 rotates, the spring 14 is stretched, the latch 12 disengages from the card slot 13, and the housing 5 is pulled out towards the end away from the sleeve 7 to realize the separation between the female socket 2 and the male socket 4.

[0039] The above has described several embodiments of the present invention in detail, but the embodiments of the present invention are not limited thereto and should not be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
