Description

Technical Field

[0001] The utility model relates to the field of connectors, belonging to the field of wiring terminals. Background Art

[0002] The terminal block is an accessory product used to achieve electrical connection and belongs to the field of connectors.

[0003] In the prior art, there is a plug and socket assembly as described in patent application number "CN202221118051.0". This patent provides a connector in which one socket is adapted to multiple different types of plugs. When the plugs are the same, the connector can be used for connectors with two different connection methods, namely crimping and spring connection. However, the plug shown in this invention has the following disadvantages during the plugging process: the plug and the socket are connected by a snap-on, and during the separation of the plug and the socket, the separation of the plug and the socket is achieved by pressing the pressing part. Therefore, during the operation, the operator's force application point is the pressing part. The pressing part of this patent has a small area, so its operable space is small, and the separation of the plug and the socket is more difficult.

[0004] In actual operation, the plug is composed of two parts. During the docking process of the two parts, the buckle is easily failed, resulting in the separation of the two parts of the shell of the plug.

[0005] The spring assembly used in the connector has no supporting and fixing structure at the tail of the spring, so the spring will be displaced during use, resulting in contact error during the docking process of the plug and the socket, making the contact resistance larger. Utility Model Content

[0006] The purpose of the utility model is to provide a connector that is convenient for workers to operate and can be quickly disassembled. The specific scheme adopted is as follows:

[0007] A connector is used to match with a socket. The connector includes a first shell and a second shell, wherein the first shell and the second shell are connected to form an installation cavity in which an electrical connector is installed. An unlocking part is provided on the first shell, and the unlocking part is used to realize the separation and connection of the connector and the socket.

[0008] Furthermore, the aforementioned unlocking portion includes a snap-in protrusion that cooperates with the socket, and a pressing portion that is an integral part of the snap-in protrusion and connected to the first shell, wherein one end of the snap-in protrusion is connected to the pressing portion, and the other end of the snap-in protrusion is a free end. When the connector is connected to the socket, the snap-in protrusion cooperates with a guide portion provided on the socket, thereby realizing the connection between the connector and the socket. When the connector is separated from the socket, the pressing portion provided on the unlocking portion is pressed, and the portion where the snap-in protrusion and the first shell are connected is a rotating axis so that the snap-in protrusion moves in a direction close to the first shell. Pressing the unlocking portion causes the connector to move away from the socket, thereby separating the connector from the socket.

[0009] Furthermore, the height of the pressing portion of the aforementioned connector is 2.1 cm higher than the plane.

[0010] Furthermore, the second shell is provided with a wire entry hole for the wire to enter, and the electrical connector is a spring assembly, wherein the spring assembly cooperates with the connector provided on the socket, and is used to fix the wire so that the wire is electrically connected to the connector on the socket.

[0011] Furthermore, the aforementioned spring assembly includes a button and a spring, wherein the button is arranged in the second shell, and the wire entry hole for the wire to enter includes a first hole segment and a second hole segment, wherein the first hole segment and the second hole segment are connected, and the second hole segment is a conical surface.

[0012] Furthermore, the first shell and the second shell are connected by snap-fitting, and the surface where the front end of the first shell contacts the second shell is an arc surface, wherein the surface of the second shell opposite to the arc surface is also an arc surface.

[0013] Furthermore, an opening guide member in contact with the spring assembly is provided on the first housing of the connector.

[0014] From the above technical content, it can be seen that the beneficial effect of the utility model is that: since the area of ​​the unlocking part is increased, the operator has a larger force application space when pressing, which can achieve rapid separation of the connector and the socket, and improve the friendliness of the operation.

[0015] An arc surface is provided between the first shell and the second shell, so that the buckle between the two shells is more secure during assembly, and a more reliable connection can be achieved.

[0016] The wire entry hole for the wire to enter includes a first hole segment and a second hole segment, wherein the first hole segment and the second hole segment are connected, and the second hole segment is a conical surface which is provided with a related smooth transition surface, so that the wire entry opening becomes larger, and the conical surface can make the wire smoothly enter the shell, avoiding difficulty in wire entry when the shell is too thin.

[0017] The second shell is provided with a fool-proof design, which can prevent the second shell from being wrongly assembled during the assembly process of the first shell, thereby improving assembly efficiency.

[0018] An opening guide is provided on the first housing, and the opening guide makes the fixing of the spring sheet assembly more stable, thereby avoiding the instability of the plugging of the connector and the socket caused by the deformation of the spring sheet assembly during the matching of the connector and the socket.

An unlocking portion 11 is provided on the first shell 1. By pressing the unlocking portion 11, the connector is moved away from the socket, so that the connector is separated from the socket.

[0034] The unlocking portion 11 includes a snap-fitting protrusion 111 matched with the socket, and a pressing portion 112 connected to the first shell 1 as an integral part with the snap-fitting protrusion 111, wherein one end of the snap-fitting protrusion 111 is connected to the pressing portion 112, and the other end of the snap-fitting protrusion 111 is a free end. When the connector is connected to the socket, the snap-fitting protrusion 111 cooperates with a guide portion provided on the socket to achieve the connection between the connector and the socket. When the connector is separated from the socket, the pressing portion 112 provided on the unlocking portion 11 is pressed, so that the snap-fitting protrusion 111 moves in a direction close to the first shell 1 with the portion connected between the unlocking portion and the first shell 1 as the rotation axis, thereby separating the connector from the socket.

[0035] The height of the pressing portion 112 of the connector is higher than 2.1 cm. The height is set so that when the connector and the socket are separated, the main force application position such as the thumb can have enough pressing stroke and area with the pressing portion 112, so that there is enough force to separate the connector and the socket.

[0036] The second shell 2 is provided with a first through hole 202 for the wire to enter, and the electrical connector is a spring assembly 220, wherein the spring assembly 220 cooperates with a connector provided on the socket and is used to fix the wire so that the wire is electrically connected to the connector on the socket.

[0037] The electrical connectors in the first and second housings of the connector may also use the structure shown in “CN202221118051.0” in addition to the structure shown in the utility model. Figure 7 and Figure 8 Crimp terminals shown.
