Description

Technical Field

[0001] The utility model belongs to the technical field of connectors and relates to a double-group insulation displacement cable female connector. Background Art

[0002] Connectors are electro-thermal mechanical devices used to connect electrical conductors and create circuits, which allow for detachable connections to transmit power and electrical signals. Signals or electrical power are transmitted through metal conductors, while plastic housings are used in connectors to isolate the metal conductors from each other. Plastic housings are also used to align the conductors and ensure that the conductors are securely locked to the female housing.

[0003] Electrical connectors are used to electrically connect different electronic products and transmit signals between them. The connectors contain conductors. The conductors in the female connector are called female terminals, while the conductors in the male connector are called male terminals or male pins. The female terminals are used to connect to the male pins, and the part that maintains the connection with the male pin is elastic and is called a bell mouth. The other end of the female terminal can be connected to the cable conductor. There are different methods for termination to the cable conductor. Insulation displacement and clamping are the most common termination methods. This female connector is such a device. It is assembled into the female connector housing to form a female connector. The female connector and male connector can be used to connect signals from one circuit board (PCB) to another circuit board (PCB) via a cable connection. One end of the connector system (male connector) is soldered to the PCB, while the other end of the connector system (female connector) terminates the terminal to the cable.

[0004] Conventional female cable connectors have terminals with only one insulation displacement termination, which results in insufficient retention of the insulation displacement termination to the cable's metal conductor, affecting reliability. The present invention installs female terminals with two sets of insulation displacement terminations in each cavity in the female housing to ensure a safe and reliable connection between the terminal and the cable.

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] A double-group insulation displacement cable female connector includes a female shell 1 and an upper cover 2. The upper cover 2 is provided on the top of the female shell 1, and a female terminal 4 is provided inside the female shell 1. Ear buckles 13 are provided on both sides of the female shell 1, and the two ear buckles 13 are symmetrically arranged. A T-shaped guide groove 14 is provided inside the ear buckle 13, and the T-shaped guide groove 14 is vertically opened on the outer wall of the female shell 1. A T-shaped guide column 5 and a buckle 12 are fixedly provided on the bottom side of the upper cover 2, and the T-shaped guide column 5 and the buckle 12 are arranged side by side, and the T-shaped guide column 5 is inserted into the inside of the T-shaped guide groove 14.

[0023] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the double-group insulation displacement cable female connector of the present invention, specifically, the outer wall surface of the female housing 1 is provided with a pre-installed card slot 8 and a fully loaded card slot 9, and the pre-installed card slot 8 is arranged at the top position of the fully loaded card slot 9.

[0024] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the double-group insulation displacement cable female connector of the present invention, specifically, the buckle 12 cooperates with the pre-installed card slot 8 and the fully loaded card slot 9.

[0025] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the double-group insulation displacement cable female connector of the present invention is specifically provided with a plurality of undercuts 7 on one side of the bottom of the female housing 1 , and the undercuts 7 are provided on one side of the female terminal 4 .

[0026] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the double-group insulation displacement cable female connector of the present invention is specifically provided with a cable panel at the front end of the upper cover 2, and a plurality of undercut lock holes 6 cooperating with undercuts 7 are opened at the bottom end of the cable panel.

[0027] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the double-group insulation displacement cable female connector of the present invention has multiple cable inlets 3 on the surface of the cable panel, and a cable window 10 is provided at the top of the upper cover 2.

[0028] The present invention uses two components to fix the female terminal 4 in the female connector, one component is the female housing 1, and the other is the upper cover 2. The female housing 1 has a cavity for accommodating the female terminal 4, and the number of cavities can be one or more. The back of the female housing 1 has one more undercut 7 than the number of cavities. The female housing 1 has an ear button 13 symmetrically on each side, and the ear button 13 provides elasticity for locking the male connector. One or more coding columns are set in front of the female housing 1. Only when the position of the coding column of the female connector is consistent with the position of the coding slot of the male connector, the male and female connectors can be correctly plugged in.

[0029] There is a pre-installed card slot 8 on each side of the female shell 1 near the rear of the ear button 13, and a full-loaded card slot 9 below the pre-installed card slot 8. There is a T-shaped guide groove 14 in each of the left and right ear buttons 13 of the female shell 1. Another component of the female connector is the upper cover 2. There is a T-shaped guide column 5 on the front of the left and right sides of the upper cover 2. The left and right guide columns of the upper cover 2 can be inserted into the T-shaped guide grooves 14 on both sides of the female shell 1. The T-shaped guide columns 5 and the T-shaped guide grooves 14 ensure that the female shell 1 and the upper cover 2 can be correctly inserted and slide up and down.

[0030] There is a clip 12 on each side of the upper cover 2, and the clip 12 and the T-shaped guide column 5 are symmetrical on the left and right. The symmetrical clips 12 on the left and right of the upper cover 2 correspond to the pre-installed card slots 8 and the fully loaded card slots 9 on both sides of the female shell 1. In addition to installing the female terminal 4 on the female shell 1, the upper cover 2 will also be installed on the female shell 1. The clips 12 of the upper cover 2 will be pre-installed in the pre-installed card slot 8. In this pre-installed position, the cable can be inserted into the cable entry 3. The front of the upper cover 2 corresponds to the position of the cavity of the female shell 1. The function of the cable window 10 is to ensure that the cable is inserted to a sufficient depth. There is also a cable baffle 11 at the front bottom of the upper cover 2. The purpose of the cable baffle 11 is to prevent the cable from being over-inserted.

[0031] There is an inverted lock hole 6 at the rear of the upper cover 2, below the cable inlet 3, at the position corresponding to the female shell 1. The number of inverted lock holes 6 is one more than the number of cable windows 10. After the cable is assembled, the buckle 12 of the upper cover 2 will be pressed from the pre-installed slot 8 to the fully loaded slot 9. At the same time, the inverted lock hole 6 of the upper cover 2 will be stuck on the inverted buckle 7 of the female shell 1 to complete the entire installation.
