Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a flip-in buckle connector. Background Art

[0002] Connectors are a type of component that electronic engineers often come into contact with. Their function is very simple: to build a bridge of communication between blocked or isolated circuits within a circuit, so that current can flow and the circuit can achieve its intended function.

[0003] The connector usually includes a socket and a plug. The plug is installed on the socket through an external lock assembly process. If the plug and the socket are assembled multiple times, the external lock assembly on it will not bounce after being pressed multiple times. And when the wire is inserted into the connector, it is easy for the wire to be wrapped around the external lock. When the socket and the plug are matched, the pin in the socket needs to be inserted into the terminal in the plug. However, in the prior art, the connector does not have a locking plate structure, which cannot ensure that the terminal is properly inserted into the plug. If the terminal is not properly inserted, it will be pushed out by the pin, causing the terminal to loosen and detach, thereby causing the circuit and signal transmission to be interrupted, resulting in the problem of insufficient stability of the existing connector.

[0004] Therefore, how to provide a connector that can establish terminal stability and avoid interruption of circuit and signal transmission is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] To this end, the present invention provides a flip-in connector to solve the problem in the prior art that the connector has no locking structure and cannot ensure that the terminal is properly inserted into the plug, resulting in interruption of circuit and signal transmission.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A flip-in connector, comprising:

[0008] A socket having a plurality of PIN positions, and positioning barriers are provided between the plurality of PIN positions;

[0009] A plug is inserted into the socket through an internal locking structure, and is provided with a plurality of slots, each of which is provided with a terminal, and the terminal is clamped in the slots;

[0010] A plug pin is inserted into a PIN position of the socket, and when the socket is mated with the plug, the plug pin is inserted into the terminal;

[0011] The wire fixing clamp comprises a flap and a fixing protrusion, one side of the flap is hingedly arranged above the plug, the bottom surface of the flap is provided with a fixing protrusion, and an opening is provided above the slot. When the flap is covered on the plug, the fixing protrusion is embedded in the opening of the slot.

[0012] Furthermore, the inner locking structure includes an inner locking piece and an inner locking groove. The inner locking groove is provided in the socket, the inner locking piece is provided on the plug, the inner locking piece is provided with a positioning protrusion, and a positioning groove is provided in the inner locking groove. When the socket is matched with the plug, the inner locking piece is inserted into the inner locking groove, and the positioning protrusion is clamped in the positioning groove.

[0013] Furthermore, both sides of the head end of the terminal are extended outwardly with a first limiting spring sheet, and both sides of the tail end of the terminal are gathered inwardly with a second limiting spring sheet. A limiting groove is provided in the slot of the plug, the first limiting spring sheet is clamped in the limiting groove, and the pin clamp is arranged between the second limiting spring sheets.

[0014] Furthermore, the fixing protrusion includes a first limiting protrusion and a second limiting protrusion, the first limiting protrusion is arranged at the front end of the flip cover, the second limiting protrusion is arranged at the rear end of the flip cover, and the fixing protrusion is embedded in the opening of the slot through the first limiting protrusion and the second limiting protrusion.

[0015] Furthermore, the first limiting protrusion is bowl-shaped, and when the fixing protrusion is embedded in the opening of the slot, the bowl-shaped top surface of the first limiting protrusion abuts against the opening of the slot.

[0016] The present invention has the following advantages:

[0017] The connector provided in the present application includes a socket, on which a plurality of PIN positions are provided, and the plurality of PIN positions are separated by positioning barriers; a plug, which is inserted into the socket through an internal locking structure, and on which a plurality of slots are provided, and terminals are inserted in the plurality of slots, and the terminals are snapped into the slots; a pin, which is inserted into the PIN position of the socket, and when the socket and the plug are matched, the pin is inserted into the terminal; a wire fixing clamp, including a flap and a fixing protrusion, one side of the flap is hingedly provided above the plug, the bottom surface of the flap is provided with a fixing protrusion, and an opening is provided above the slot, and when the flap is covered on the plug, the fixing protrusion is embedded in the opening of the slot.

[0018] The present application assembles the plug and the socket through an inner lock structure. The inner lock structure has good stability, its elasticity is not easy to change, and the setting of the inner lock prevents the wire from being accidentally entangled in the inner lock. When the socket and the plug are matched, it is only necessary to set the flip cover on the plug, and the fixing protrusion on the flip cover can push the terminal to the correct position, so that the terminal is fixed in the plug. When the pin is inserted into the terminal, the terminal will not be pushed out by the pin, and the terminal is not easy to fall out of the plug, which increases the stability of the connector.

DETAILED DESCRIPTION

[0029] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1-6 As shown, a flip-in connector includes a socket 1, a plug 2, a pin 3 and a wire clamp 4. The socket 1 is provided with a plurality of PIN positions 5, and a positioning fence 6 is provided between the plurality of PIN positions 5. The positioning fence 6 between the pins 3 on the socket 1 has the function of locating the position of the PIN pins to prevent the PIN pins from being twisted.

[0031] like Figure 2 As shown, the plug 2 is inserted into the socket 1 through the inner locking buckle structure 9, and the inner locking buckle structure 9 includes an inner locking piece 901 and an inner locking groove 902. The inner locking groove 902 is provided in the socket 1, and the inner locking piece 901 is provided on the plug 2. When the plug 2 is inserted into the socket 1, the inner locking piece 901 on the plug 2 is squeezed until the position of the inner locking piece 901 moves into the inner locking groove 902 in the socket 1. At this time, the socket 1 and the plug 2 are connected. In order to strengthen the connection between the socket 1 and the plug 2, a positioning protrusion 10 is provided on the inner locking piece 901, and a positioning groove 11 is provided in the inner locking groove 902. When the socket 1 and the plug 2 are matched, the inner locking piece 901 is inserted into the inner locking groove 902, and the positioning protrusion 10 is clamped in the positioning groove 11, so that the plug 2 will not easily fall out of the socket 1. The present application assembles the plug 2 and the socket 1 through the inner locking structure 9. The inner locking structure 9 has good stability, its elasticity is not easily changed, and the setting of the inner locking structure 9 improves the connection stability of the plug 2 and the socket 1.

[0032] In the prior art, the wires on the plug are easily entangled on the locking piece, in order to avoid the entanglement of the wires. The bottom of the plug 2 provided by the present invention is provided with two "└"-shaped blocks, and the head end of the inner locking piece 901 is arranged between the two blocks and surrounded by the two blocks. When the plug 2 is connected to the wire, the wire can be prevented from being entangled on the inner locking piece 901. When in use, the plug 2 is inserted into the socket 1, and the inner locking piece 901 between the two blocks is squeezed upward, so that the inner locking piece 901 is placed in the groove surface between the two blocks, avoiding accidental touch or wire entanglement, so that the wires on the plug 2 are arranged neatly, and the connection stability between the wires and the plug 2 is improved.

[0033] like Figure 5-6 As shown, the pin 3 is inserted into the PIN position 5 of the socket 1, and when the socket 1 is matched with the plug 2, the pin 3 is inserted into the terminal 8. The plug 2 is provided with a plurality of slots 7, and the plurality of slots 7 are all provided with terminals 8, and the terminals 8 are clamped in the slots 7. Both sides of the head end of the terminal 8 are extended outwardly to provide a first limit spring sheet 12, and both sides of the tail end of the terminal 8 are gathered inwardly to provide a second limit spring sheet 13. The slot 7 of the plug 2 is provided with a limit slot 14, the first limit spring sheet 12 is clamped in the limit slot 14, and the pin 3 is sandwiched between the second limit spring sheets 13.

[0034] The specific process of installing the terminal 8 on the plug 2 is as follows: insert the terminal 8 into the plug 2 from the open end of the slot 7. At this time, the first limit springs 12 on both sides of the terminal 8 are squeezed inwards until the terminal 8 reaches the fixed position, and the first limit springs 12 open outwards to restore. At this time, the first limit springs 12 on both sides are both clamped in the corresponding limit grooves 14. When the socket 1 is matched with the plug 2 and the pin 3 is inserted into the terminal 8, the pin 3 is clamped in the second limit springs 13 on both sides. At this time, the electrical connection between the terminal 8 and the pin 3 is established.

[0035] like Figure 1 As shown, the wire clamp 4 includes a flip cover 401 and a fixing protrusion 402, one side of the flip cover 401 is hingedly arranged above the plug 2 through a rubber, the bottom surface of the flip cover 401 is provided with a fixing protrusion 402, and an opening is provided above the slot 7. The fixing protrusion 402 includes a first limiting protrusion 4021 and a second limiting protrusion 4022, the first limiting protrusion 4021 is arranged at the front end of the flip cover 401, and the second limiting protrusion 4022 is arranged at the rear end of the flip cover 401, and the fixing protrusion 402 is embedded in the opening of the slot 7 through the first limiting protrusion 4021.

[0036] In order to enable the terminal 8 to reach the accurate position, a flip cover 401 and a fixing protrusion 402 are provided. By covering the flip cover 401 on the plug 2, the fixing protrusion 402 is embedded in the opening of the slot 7, so that the fixing protrusion 402 can press the terminal 8 inwards and push the terminal 8 to the accurate position. Specifically, as Figure 4As shown, when the flip cover 401 is covered on the plug 2, the fixing protrusion 402 is embedded in the opening of the slot 7. The first limiting protrusion 4021 is bowl-shaped, and the connector is an elastic structure, so that the first limiting protrusion 4021 can be squeezed into the slot 7. When the fixing protrusion 402 is embedded in the opening of the slot 7, the bowl-shaped top surface of the first limiting protrusion 4021 abuts against the opening of the slot 7, so that the flip cover 401 can be fixed on the plug 2. When the second limiting protrusion 4022 enters the slot 7, it squeezes the terminal 8 internally and pushes the terminal 8 to the correct position.

[0037] The bevels on both sides of the second limiting protrusion 4022 allow the terminal 8 to be inserted in any direction. When the terminal 8 is not properly inserted into the plug 2, the flip cover 401 is flipped downward to allow the first limiting protrusion 4021 to be embedded in the opening of the slot 7, and the beveled surfaces on both sides of the second limiting protrusion 4022 push the terminal 8 to move in the plug 2. The beveled surfaces on both sides of the second limiting protrusion 4022 can push any one of the upper and lower end faces of the terminal 8, so that the terminal 8 can be inserted in any direction.

[0038] When the socket 1 and the plug 2 are mated, the flip cover 401 only needs to be placed on the plug 2, and the fixing protrusion 402 on the flip cover 401 can push the terminal 8 to the correct position, so that the terminal 8 is fixed in the plug 2. When the pin 3 is inserted into the terminal 8, the terminal 8 will not be pushed out by the pin 3, and the terminal 8 is not easy to fall out of the plug 2, thereby increasing the stability of the connector.

[0039] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
