Description

Technical Field

[0001] The utility model belongs to the field of connection ports, and in particular relates to a female end connector. Background Art

[0002] The compressor connector of the car air conditioner is usually a board-to-board male-female connection, and the male end is mostly a glass terminal. The more common glass terminal contacts on the market usually have three points, corresponding to the neutral wire, the live wire, and the ground wire respectively. However, when wiring, since the wiring method used is point-to-point individual wiring, it is very unfriendly for users who are not familiar with the specific arrangement of the terminals. Wiring errors often occur, which makes it very inconvenient to replace and repair the compressor.

[0003] In addition, one side of the glass terminal is usually connected to the PCB board, and the other end of the wiring is usually also connected to the PCB board. Once the wiring contacts are wrong, it is easy to cause the two PCB boards to burn out. In addition, through point-to-point separate wiring, it is also easy to cause the line to loosen and shake during the driving of the car. After long-term use, there will be problems such as poor line contact and unstable current transmission.

[0004] Therefore, a new design is needed that can make it more convenient for users to connect the glass terminal. Utility Model Content

[0006] In order to solve the above problems, the technical solution adopted by the utility model is as follows:

[0007] A female connector includes a terminal connected to a connector, a conductive part and an insulating shell, wherein the conductive part includes a conductive clip and a body conductor, the conductive clip and the body conductor are arranged inside the insulating shell, a through hole is provided at a portion of the insulating shell located at a connection contact between the conductive clip and the body conductor, a plurality of conductive clips and body conductors are arranged and correspond to each other one by one, and the shape of the insulating shell is an asymmetric shape determined according to the number of conductive clips.

[0008] The insulating shell comprises an insulating shell and an insulating cover plate, the conductive part is arranged in the insulating shell, and the insulating cover plate is connected to the insulating shell through a tenon.

[0010] The side surface of the insulating shell is provided with a plurality of flange structures for fixing.

[0015] The lengths of the multiple flow guides are determined according to the specific positions of their connection points.

[0016] The conductive clip is arranged at a specific position inside the insulating housing to match the shape of the terminal to be connected.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The utility model is designed for the glass terminal of the compressor of the vehicle air conditioner. The position of the conductive clip is determined by the asymmetrically shaped insulating shell. During assembly, the connection contacts are accurately positioned at the only angle that can be fully plugged in, thus avoiding the problem of misconnection between the two boards.

[0024] The utility model is further described below in conjunction with specific embodiments.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model is mainly designed for the glass terminal commonly used on the vehicle air-conditioning compressor, which mainly includes an insulating shell and an internal conductive part, and can complete the wiring of the glass terminal more accurately, quickly and stably.

[0026] The insulating shell mainly includes an insulating shell 1 and an insulating cover plate 2. The overall structure of the insulating shell 1 is an asymmetrical shape. The portion where the insulating shell 1 is connected to the glass terminal is provided with through holes corresponding to the number of terminals according to the actual shape of the glass terminal. The asymmetrical shell and the through holes opened corresponding to the glass terminal ensure that there is only a single connector installation method when wiring using the insulating shell, and the wrong wires will not be connected due to unclear circuits represented by specific terminal contacts. This is commonly known as a fool-proof design, which can effectively avoid the problem of burning circuit boards due to wrong wires during installation or maintenance wiring.

[0027] Inside the insulating shell, a conductive part for circuit connection is provided, and the conductive part mainly includes a conductive clip 3 and a conductor 4. The conductive clip 3 is provided at the position where the insulating shell 1 is connected to the glass terminal. When the glass terminal passes through the through hole opened in the insulating shell 1, it will contact the conductive clip 3 and be fixed by the conductive clip 3.

[0028] In this embodiment, the structure of the conductive clip 3 is a buckle-type clip, which is provided with a symmetrical arc-shaped contact surface. When fixing the glass terminal, it can provide it with sufficient clamping force and a larger contact area, thereby ensuring a firm connection between the conductive clip 3 and the glass terminal, and ensuring that the current transmission can be more stable.

[0029] The other end of the conductive clip 3 is provided with a U-shaped welding groove, and the conductive body 4 is sandwiched and welded in the welding groove. The specific structure is as follows: Figure 4 There are multiple conductive clips 3 in the insulating housing 1, and the number of the conductive clips 3 is changed according to the number of glass terminals. Each conductive clip 3 is connected to a conductor 4, and the internal structures of the conductive clips 3 and the conductor 4 installed in the insulating housing 1 are insulated and isolated from each other.

[0030] The shape of the flow guide 4 is mainly bent according to the shape of the insulating shell 1. At the end of the flow guide 4, a connecting contact 5 extends toward the side of the insulating cover 2. The insulating cover 2 is provided with a through hole corresponding to the connecting contact for the connecting contact of the flow guide 4 to pass through.

[0031] The connecting contact 5 of the flow guide 4 extending out of the insulating shell on one side of the insulating cover 2 is connected to the control panel that needs to be connected to the glass terminal of the compressor. The connection is usually made to a PCB board on which a control circuit is arranged. In order to better connect with the PCB board, the connecting contact 5 can be adjusted to a specific position according to the connection point preset on the PCB board. The adjustment method is to adjust the position of the terminal connecting contact 5 by changing the length of the flow guide 4, which will be more flexible when designing the overall contact.

[0032] The reason why a U-shaped welding groove is used at the connection point between the conductive clip 3 and the flow conductor 4 is that, compared with the mainstream V-shaped welding groove, the positioning accuracy and soldering efficiency of the U-shaped welding groove are greatly improved. In actual production, this structure can more conveniently assemble the conductive clip 3 and the flow conductor 4 of different lengths.

[0033] The insulating housing 1 and the insulating cover 2 are both detachable structures. In this embodiment, the fixing method adopted is to fix the housing 1 with a fixing tenon 6. Figure 1 As shown, the position of the fixing tenon 6 is determined according to the special shape of the insulating shell 1, and a buckle is provided at the corresponding position of the insulating cover plate 2. During actual installation, the connecting contact 5 of the flow conductor 4 is passed through the through hole of the insulating cover plate 2, and then the insulating cover plate 2 and the insulating shell 1 are closed, and the tenon is buckled to complete the assembly. This detachable structure is convenient for repair and replacement when the relevant parts of the conductive part are damaged, because each group of conductive clips 3 and flow conductors 4 of the conductive part are installed in isolation from each other, so the damaged group of conductive parts can be replaced separately. What is shown in this embodiment and the accompanying drawings is a connector structure for connecting three straight-row glass terminals. If it is used on a device with a larger number of terminals, the number of groups of internal conductive parts will also increase accordingly. If damage occurs, the entire set of conductive parts will be directly replaced, which will undoubtedly greatly increase the maintenance cost.

[0034] In order to facilitate users to distinguish the direction and front and back of the connector, the polarity of the corresponding terminal, the polarity of the connecting contact 5, the installation direction, etc. can be marked on the surface of the insulating cover 2 to provide users with simple usage guidance.

[0035] Above the insulating cover plate 2, various PCB boards are usually connected board to board for control, so a plurality of fixing flanges 7 are also provided on the periphery of the insulating shell 1, and the insulating shell and the board-connected PCB boards are further fixed by the fixing flanges 7 to prevent them from loosening, resulting in poor contact and unstable current transmission.

[0036] The main feature of this solution is the asymmetric shape of the insulating shell, which ensures that the user can only connect the connector to the glass terminal on the compressor in a pre-set spatial posture when wiring the glass terminal. In order to better explain the structure of this solution, a structural diagram of a product is shown in the attached figure of the specification, but this structure does not limit this solution. Its main core is still the overall asymmetry of the insulating shell. Similarly, the number of conductive parts shown in the attached figure is three, and the structure of the three groups of conductive clips 3 and the body 4 is not a limitation of this solution, but is only used to show a structural solution after the product is actually put into production.
