Description

Technical Field

[0001] The utility model relates to the technical field of plug-in terminals, in particular to a connector with reliable wire connection. Background Art

[0002] Existing connectors generally include a male plug and a female socket for inserting the male plug and forming a plug-in fit. At the same time, the general female socket includes a female rubber shell and a female terminal arranged in the female rubber shell. The male plug includes a male rubber shell and a male terminal arranged in the male rubber shell, wherein the male and female terminals form a plug-in fit, and the other end of the male rubber shell relative to the plug-in to the female rubber shell and the other end of the female rubber shell relative to the plug-in to the male rubber shell are respectively used to connect with the wire; although the male plug and the female socket of some existing connectors can be reliably connected, after the male terminal is set in the male rubber shell or the female terminal is set in the female rubber shell, when pulling occurs or shaking occurs during operation, it is very easy for the female terminal or the male terminal to fall out of the corresponding male or female rubber shell, thereby causing the design of the connector to be unreliable. Summary of the invention

[0003] In view of the above-mentioned shortcomings, the utility model provides a connector which can ensure reliable wire connection and prevent the male and female terminals from accidentally falling out of the corresponding male and female rubber shells.

[0004] In order to achieve the above purpose, the utility model adopts a connector with reliable wire connection, including a limiter, a male plug, and a female socket for inserting the male plug and forming a plug-in fit, the female socket including a female rubber shell and a female terminal arranged in the female rubber shell, the male plug including a male rubber shell and a male terminal arranged in the male rubber shell, through the plugging of the male and female rubber shells, a contact connection is formed between the male and female terminals, the other end of the male rubber shell relative to the plug-in with the female rubber shell, and the other end of the female rubber shell relative to the plug-in with the male rubber shell are respectively used for connecting with external wires, the limiter is respectively arranged and limited on the other end of the male rubber shell relative to the plug-in with the female rubber shell, and the other end of the female rubber shell relative to the plug-in with the male rubber shell, and the limiter is also provided with a penetration position for the external wire to pass through.

[0005] The beneficial effect of the above structure is that: by respectively involving a limiting member on the male rubber shell of the male end connector of the connector and the female rubber shell of the female end socket, and at the same time, on the male and female rubber shells relative to the other end that can be plugged in, the limiting member can limit the male and female rubber shells, and the limiting member also involves a penetration position through which the wire can pass, so that after the limiting member is involved in the connector of the utility model, the male and female terminals can be limited in the corresponding male and female rubber shells by the action of the limiting member, thereby avoiding the male and female terminals from accidentally falling out of the male and female rubber shells due to shaking or pulling during use of the male end connector or the female end socket, thereby ensuring the reliability of the design of the male end connector and the female end socket, in addition, through the action of the penetration position, the limiting member can limit the reliable position while not affecting the reliable penetration of the wire, thereby also ensuring the rationality of the design of the connector involved in the utility model.

[0006] The utility model is further configured that a convex block is formed on the outer side wall of the other end of the male rubber shell relative to the female rubber shell, and a convex block is formed on the outer side wall of the other end of the female rubber shell relative to the male rubber shell, respectively; an extension portion is formed on the limit member relative to the direction toward the male and female rubber shells, and the extension portion extends to the outside of the outer side walls of the male and female rubber shells, respectively, and a snap groove is formed on the extension portion, and the limit member is limited on the male and female rubber shells respectively through the snap-fitting of the convex block and the snap groove.

[0007] Through the above arrangement, the limiting member can be reliably connected and limited on the male connector and the female socket.

[0008] The utility model is further configured that an embedded auxiliary matching block is formed on the limiting member, the embedded auxiliary matching block and the extension portion are designed in the same direction, and the embedded auxiliary matching block is distributed on the side of the penetration position and is designed to avoid.

[0009] Through the above-mentioned arrangement, when the limit piece is assembled and limited on the male and female rubber shells corresponding to the male end connector and the female end socket, it can be first inserted into the corresponding male and female rubber shells through the embedded auxiliary matching block, thereby avoiding the situation where the limit piece is difficult to align when it is matched to the male and female rubber shells if there is no embedded auxiliary matching block. This ensures the convenience of the limit piece to match on the male end connector and the female end socket.

[0010] The utility model is further configured such that the number of the extension parts is two, and they are respectively distributed on the two side edges of the limiter, and a matching block setting space is formed between the two extension parts, and the embedded auxiliary matching blocks are distributed in the matching block setting space;

[0011] The insertion position is two through grooves for the zero and live wires to pass through respectively. The two through grooves are structures formed by the edges of the two object surfaces of the extension part being respectively recessed inwards. The two groove walls on the through grooves face the male and female terminals, and the two groove walls are of a cancelling design, and form an internal and external connection of the limiter, and constitute the external zero and live wires that can extend from the two groove wall positions on the through grooves into the corresponding male and female rubber shells, and form a connection with the male and female terminals;

[0012] The embedded auxiliary matching block is an embedded structure that is engaged on the through groove and eliminates the position of the two groove walls. It extends in the same direction as the extension part. The embedded structure is retracted and forms a non-interference design with the other end of the male rubber shell that is connected to the female rubber shell and the other end of the female rubber shell that is connected to the male rubber shell.

[0013] By increasing the number of extensions to two and distributing them on the edges of both sides of the limiter, the limiter can be reliably limited on the male and female rubber shells; at the same time, by setting the penetration position to two through grooves that can be used for the zero and live wires to pass through respectively, and the specific structure of the two through grooves is a structure formed by the edges of the two object surfaces of the self-extending parts being respectively recessed inwards, the two groove walls on the through grooves face the male and female terminals, and the two groove walls are of a cancelling design, and form an internal and external connection of the limiter, and constitute that the external zero and live wires can extend from the two groove wall positions on the through grooves into the corresponding male and female rubber shells, and connect with the male and female terminals. The embedded auxiliary matching block is arranged to be engaged with the through groove, the position of the two groove walls is cancelled, and the embedded structure extends in the same direction as the extension part, and the embedded structure is retracted, thereby further ensuring that the embedded auxiliary matching block can be reliably inserted into the male and female rubber shells, and at the same time, it can be avoided that the design of the embedded auxiliary matching block is unreliable, causing interference when the male and female rubber shells are matched relative to the other end that can be plugged in, thereby causing unreliable clamping between the limiter and the male and female rubber shells.
