Description

Technical Field

[0001] This utility model relates to a connector, specifically a connector suitable for access control systems. Background Technology

[0002] Currently available smart video intercom systems have some common limitations when connected to wall-mounted panels:

[0003] 1. The connectors used are generally large, so the products need to be made thicker;

[0004] 2. In order to save space, waterproofing and dustproofing were not done, or the cables used were not protected by sheaths, resulting in a reduced service life;

[0005] 3. It has multiple sets of connectors, resulting in complex wiring and relatively high cost.

[0006] Therefore, it is necessary to invent an integrable, small-sized, relatively low-cost, waterproof and dustproof connector. Utility Model Content

[0007] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a connector suitable for access control systems. It features an ultra-thin design (only 10.5mm), a 90-degree plug-in structure, waterproof and dustproof performance, a 3.5mm wide spacing, and 4-12 channel optional configurations. It integrates a multi-functional interface, is equipped with a durable cable sheath and PVC cable clips, and achieves reliable protection through a waterproof ring screw locking structure, significantly improving installation convenience and product lifespan.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: A connector suitable for access control systems includes pin headers, a plastic upper cover, a plastic lower cover, terminals, a waterproof ring, an outer mold, screws, and cables. The plastic upper cover and the plastic lower cover are snapped together to form a plastic shell. Multiple terminals are snapped inside the plastic shell, and a waterproof ring is provided on the outside. The terminals and pin headers are inserted and pulled at 90°. After the terminals are riveted onto the cables, they are snapped into the plastic shell. The terminals, cables, and plastic shell are connected as one unit by filling with the outer mold. The outer mold is fixed to the panel of the access control system by screws.

[0009] Preferably, the pin header is mounted on the PCB as a male terminal.

[0010] Preferably, the pin header has a 3.5mm pitch.

[0011] This utility model has the following beneficial effects:

[0012] 1. The connector is only 10.5mm thick from the PCB board end to the outer surface of the back cover of the panel. The terminals and pins are replaced with 90-degree plugs and pulls. The whole device is waterproof and dustproof, effectively reducing the thickness of the product and conforming to the current mainstream aesthetic.

[0013] 2. This connector uses a 3.5mm pitch, which is wider than the connectors generally used for signal transmission, giving installers a better experience during installation.

[0014] 3. This connector has multiple options, ranging from 4 to 12 channels. The terminals and pin headers can also be arranged in two rows to achieve more channels, integrating various functional ports into a single interface and merging the original power interface and communication interface.

[0015] 4. The connector cable has a sheath and PVC cable clips, and the cable can withstand 90 degrees of swaying up, down, left, and right, increasing its service life and reducing maintenance costs.

[0016] 5. The connector female end is equipped with a waterproof ring. The waterproof ring is pressed into the back cover of the panel by screws to achieve the effect of waterproofing and dustproofing. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments;

[0018] Figure 1 This is an exploded structural diagram of the present invention;

[0019] Figure 2 This is a schematic diagram of the assembly of the pin header and terminals of this utility model;

[0020] Figure 3 This is a schematic diagram illustrating the use of this utility model. Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Reference Figure 1-3 The specific implementation adopts the following technical solution: A connector suitable for access control systems includes a pin header 1, a plastic upper cover 2, a plastic lower cover 3, terminals 4, a waterproof ring 5, an outer mold 6, screws 7, and cables 8. The plastic upper cover 2 and the plastic lower cover 3 are snapped together to form a plastic shell. Multiple terminals 4 are snapped inside the plastic shell and a waterproof ring 5 is provided on the outside. The terminals 4 are inserted and pulled into the pin header 1 at a 90° angle. After the terminals 4 are riveted onto the cables 8, they are snapped into the plastic shell. The terminals 4, cables 8, and plastic shell are connected as one unit by the filling of the outer mold 6. The outer mold 6 is fixed to the panel of the access control system by screws 7.

[0023] It is worth noting that the pin header 1 is mounted on the PCB as a male terminal.

[0024] In addition, the pin header has a 3.5mm pitch.

[0025] In this specific embodiment, the pin headers are 3.5mm pitched and are of the insert type. They are mounted on the PCB as the male end of the entire connector, and the terminals are mounted on the upper and lower plastic covers as the female ends of the connector, forming a 90-degree insertion and removal structure with the pin headers.

[0026] The processing steps of this specific embodiment are as follows: First, make a terminal on each core wire of the cable, insert the cable into the plastic lower cover, then fix the terminal on the plastic lower cover, fasten the plastic upper cover, and then put it into the mold to injection mold the outer mold. At this time, the cable and the plastic shell are fixed. Then attach the waterproof ring, and finally install two screws.

[0027] like Figure 3 As shown, when using this connector set, a 10.5mm space should be reserved between the product PCB surface and the back cover panel. Two screw holes with the same spacing should be reserved on the back cover. Assemble the pin header on the PCB. Insert the female terminal into the pin header, tighten the screws, and the installation is complete.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
