Description

Technical Field

[0001] The present application relates to the field of connectors, and in particular to a flat female electrical connector. Background Art

[0002] In the field of electronic device connectivity, flat female electrical connectors are widely used due to their small size, stable connection, and ease of integration. Traditional flat female electrical connectors typically include a connector body and a slot within the connector body that receives and mates with a corresponding wire-end connector to achieve circuit connection and signal transmission.

[0003] However, with the increasing miniaturization and integration of electronic devices, higher requirements are being placed on the thickness and volume of flat female electrical connectors. Traditional flat female electrical connectors are often too thick to meet the extreme space utilization requirements of modern electronic devices. Utility Model Content

[0004] The purpose of this application is to provide a flat female electrical connector. By cleverly arranging the lower portion of the slot to penetrate the bottom of the connector body, this application achieves a lightweight connector and provides support for the bottom surface of the wire end connector via a PCB board. This design meets the requirements of modern electronic devices for miniaturization and integration.

[0005] A flat female electrical connector includes a connector body having a front face and a bottom; a slot disposed within the connector body, extending rearward from the front face and configured to receive and mate with a corresponding wire end connector; wherein the lower portion of the slot extends through the bottom of the connector body to reduce the thickness of the connector and allow the bottom surface of the wire end connector to be supported by a PCB.

[0006] In one embodiment, a long slope surface is provided at the inlet end of the slot, and the long slope surface gradually extends from the edge of the slot to the interior of the slot.

[0007] In one embodiment, a convex groove is provided on the upper surface of the connector body, and the convex groove extends downward from the upper surface of the connector body to the slot. The convex groove includes an anti-mistake portion and a limiting portion. The anti-mistake portion is used to prevent the insertion direction of the wire end connector, and the limiting portion is used to limit the forward and backward movement of the wire end connector after mating.

[0008] In one embodiment, mounting grooves are respectively provided on both sides of the connector body close to the entrance end of the slot, and fixing plates are installed in the mounting grooves.

[0009] In one embodiment, the bottom surface of the connector body is provided with a mounting leg, and a hollow slot is formed in the middle of the mounting leg and extends along the length direction of the mounting leg.

[0010] In one embodiment, the mounting leg is cylindrical, and a guide portion is arranged at the lower end of the mounting leg.

[0011] In one embodiment, the bottom surface of the connector body is provided with a welding heat dissipation slot.

[0012] The application has the following beneficial effects:

[0013] The slot of the conventional connector is usually arranged completely inside the connector body and does not intersect with the bottom of the connector body. This means that the thickness of the connector body needs to be large enough to accommodate the entire slot structure. The application reduces the use of materials in the vertical direction of the connector body by allowing the lower part of the slot to directly penetrate the bottom of the connector body. This design allows the connector body to maintain a smaller thickness without the need to accommodate the entire slot, thereby achieving a significant reduction in thickness. In addition, the application reduces unnecessary material use and improves space utilization through the slot penetration design. This design allows the connector to maintain sufficient strength and stability while minimizing the thickness. BRIEF DESCRIPTION OF DRAWINGS

[0025] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 Figure 2 As shown, the flat female end electrical connector A and the wire end connector B are schematic diagrams before and after being plugged in.

[0027] like Figure 3 As shown, the flat female end electrical connector includes a connector body 1 and a slot 2. The connector body 1 has a front face C and a bottom D, wherein the front face C is the face that mates with the line end connector, and the bottom is the face that is used to connect to the PCB board E. The slot 2 is provided in the connector body 1, and a PIN pin 3 is provided in the slot 2. The slot 2 extends backward from the front face C to the middle of the connector body for receiving and mating with the corresponding line end connector. The lower part of the slot 2 passes through the bottom of the connector body. This application reduces the material usage of the connector body 1 in the vertical direction by allowing the lower part of the slot 2 to directly pass through the bottom of the connector body 1. Figure 5 As shown, this design eliminates the need for the connector body 1 to maintain a substantial thickness to accommodate the entire slot 2, thereby significantly reducing thickness. Furthermore, the present invention utilizes a through-hole design at the bottom of the slot 2, which not only reduces unnecessary material usage but also improves space utilization. This design minimizes the thickness of the connector while maintaining sufficient strength and stability.

[0028] like Figure 3 As shown, in this embodiment, the entrance end of the slot 2 has two long sloped surfaces 4. These sloped surfaces 4 extend from the edge of the slot 2 and gradually extend into the interior of the slot 2 at a certain angle. The long sloped surfaces 4 allow for a smooth transition during the insertion of the cable end connector, preventing interference resistance generated prematurely at the beginning of the insertion of the cable end connector, thereby ensuring that the cable end connector can be smoothly and accurately inserted into the slot 2.

[0029] like Figure 2As shown, in this embodiment, the upper surface of the connector body 1 is provided with a convex groove 5, which extends downward from the upper surface of the connector body 1 to the slot 2. The convex groove 5 includes a locking portion 51 and a stopper 52. The locking portion 51 is designed to prevent the cable end connector from being inserted in the incorrect direction through its specific shape and size, ensuring that only cable end connectors that conform to the predetermined orientation can be successfully connected, effectively avoiding damage or functional failure caused by incorrect insertion. The stopper 52 restricts the forward and backward movement of the cable end connector after it is correctly inserted, ensuring a stable and reliable connection.

[0030] like Figure 3 As shown, in this embodiment, mounting grooves are provided on both sides of the connector body 1 near the entrance end of the slot 2, and fixing plates 6 are installed in the mounting grooves. The fixing plates 6 can be fixed to the circuit board or other mounting surface by welding, screws, or other fasteners, effectively preventing the connector assembly from loosening or shifting during use.

[0031] like Figure 3 As shown, in this embodiment, the bottom surface of the connector body 1 is provided with a mounting foot 7. A clearance groove 71 is defined in the center of the mounting foot 7 and extends along the length of the mounting foot 7. This groove 71 serves to mitigate shrinkage caused by uneven thickness during the injection molding process, ensuring the dimensional stability and structural integrity of the connector body 1 and the mounting foot 7. The mounting foot 7 is cylindrical, with a guide portion provided at its lower end.

[0032] The guide portion may be conical or in other shapes that are easy to insert, so that the mounting foot 7 can pass through the reserved hole on the circuit board or other mounting medium more smoothly, reducing the difficulty of installation and the risk of damage.

[0033] like Figure 3 As shown, in this embodiment, the bottom surface of the connector body is provided with a soldering heat dissipation groove 11. This provides an effective heat dissipation channel when soldering the PIN pins 3 or the mounting plate, and during connector operation. Heat generated by the connector can be quickly dissipated through the heat dissipation groove, thereby reducing the connector temperature and improving its operational stability and service life.
