Description

Technical Field

[0001] The utility model belongs to the field of electronic equipment, and in particular relates to a connector. Background Art

[0002] A connector is also called a connector, which is a device that connects two active devices and is used to transmit current or signals. The connector consists of a connector plug and a connector plug socket. Among them, the female connector plug consists of a plug housing and a female terminal arranged in the plug housing, and the front end of the female terminal is provided with a socket for plugging with the male terminal in the connector plug socket. In order to better contact with the male terminal, the socket is usually composed of two elastic clips arranged oppositely. However, there are still some disadvantages: 1. The clamping strength of the elastic clip is not ideal, and there is no locking function between it and the male terminal, which easily causes the male terminal to fall off; 2. The stability of the female terminal in the plug housing is poor, and there is no unlocking function. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a connector plug with better clamping force and locking and unlocking functions.

[0005] The connector plug is characterized in that a retaining spring is integrally formed at the bottom of the socket, a hanging platform for hanging and cooperating with the retaining spring is provided at the bottom of the plug cavity of the plug housing, and an unlocking hole is provided at the front end of the plug housing at the position corresponding to the hanging platform.

[0006] The connector plug is characterized in that a guide groove is provided at the bottom of the plug cavity of the plug housing corresponding to the rear of the hanging platform.

[0007] The connector plug is characterized in that the socket of the female terminal is square, and a positioning step is provided in the plug housing to cooperate with the socket.

[0008] The connector plug is characterized in that a lock buckle is integrally formed on the top of the plug housing, the lower end of the lock buckle is connected to the plug housing through an elastic connecting column, and a reinforcing positioning rib is provided behind the elastic connecting column.

[0009] The connector plug is characterized in that the crimping pins consist of a first crimping pin for crimping the conductor of the wire and a second crimping pin for crimping the insulating layer of the wire.

[0010] The connector plug is characterized in that fool-proof ribs are provided on both sides of the plug housing.

[0011] The advantages of the connector plug of the utility model are as follows: when the male terminal is inserted into the plug-in port of the female terminal, in addition to the clamping force of the first elastic clamping piece itself, the second elastic clamping piece is squeezed, and its supporting feet will be supported on the bottom surface of the plug-in port, thereby generating a greater reaction force, so that the male terminal can be firmly clamped, and the barbs will pierce the surface of the male terminal to play a locking role, thereby greatly improving the clamping force and preventing the male terminal from falling off.

[0017] like Figure 1-4As shown, the connector plug of the utility model comprises a plug housing 1 and a female terminal 2 arranged in the plug housing 1. The plug housing 1 is provided with a group of plug-in cavities 3 for accommodating the female terminal 2. The front end of the female terminal 2 is provided with a socket 4, and the rear end of the female terminal 2 is provided with a crimping foot 5, and the crimping foot 5 is used to crimp the wire. The front end of the socket 4 of the female terminal 2 is integrally formed with a clamping mechanism 6, and the clamping mechanism 6 includes an arc-shaped portion 7 extending out of the socket 4 and a first elastic clamping piece 8 extending into the socket 4 and obliquely arranged, and the front end of the first elastic clamping piece 8 is formed by bending to form an obliquely arranged second elastic clamping piece 9. The inclination angles of the first elastic clamping piece 8 and the second elastic clamping piece 9 are ideally 45-60 degrees. The bottom of the second elastic clamping piece 9 is formed by bending to form a supporting foot 10 close to or attached to the bottom surface of the socket 4. It is ideal that the support leg 10 leaves 1-2mm between the bottom surface of the socket 4. If it is directly attached to the bottom surface of the socket 4, it is easy to cause the male terminal to be inserted too tightly. The top surface of the socket 4 is integrally stamped with a barb 11 above the first elastic clamping piece 8. The front end of the plug housing 1 is provided with a socket 12 adapted to the socket 4 for the male terminal to be inserted. The plug housing 1 is provided with a positioning groove 13 adapted to the arc portion 7 to play a role in positioning the female terminal 2.

[0018] Preferably, a stop spring 14 is integrally formed at the bottom of the socket 4, a hanging platform 15 is provided at the bottom of the plug cavity 3 of the plug housing 1 to be hung and matched with the stop spring 14, and an unlocking hole 16 is provided at the front end of the plug housing 1 corresponding to the hanging platform 15. When the female terminal 2 is inserted, the stop spring 14 is hung on the hanging platform 15 to play a role in stopping the withdrawal. If the female terminal 2 is to be removed, a tool such as a rod is inserted into the unlocking hole 16 to separate the stop spring 14 from the hanging platform 15.

[0019] Preferably, a guide groove 17 is provided at the bottom of the insertion cavity 3 of the plug housing 1 corresponding to the rear of the hanging platform 15. The retraction spring 14 is inserted into the hanging platform 15 along the guide groove 17, so that the insertion is smoother.

[0020] Preferably, the socket 4 of the female terminal 2 is in a square shape, and a positioning step 18 is provided in the plug housing 1 to cooperate with the socket 4, so as to further improve the stability of the installation of the female terminal 2.

[0021] Preferably, a lock buckle 19 is integrally formed on the top of the plug housing 1, and the lower end of the lock buckle 19 is connected to the plug housing 1 through an elastic connecting column 20, and a reinforcing positioning rib 21 is provided behind the elastic connecting column 20. The reinforcing positioning rib 21 is used to improve the connection strength of the elastic connecting column 20 and to position the lock buckle 19 after it is unlocked and pressed into place, so as to prevent the elastic connecting column 20 from breaking.

[0022] Preferably, the crimping pin 5 is composed of a first crimping pin 22 for crimping the conductor of the wire and a second crimping pin 23 for crimping the insulating layer of the wire, so as to improve the connection strength between the wire and the conductor.

[0023] Preferably, foolproof ribs 24 are provided on both sides of the plug housing 1 to prevent the plug housing 1 from being inserted in the reverse direction.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention are included in the protection scope of the present invention.
