Description

Injection molding type female wire harness

Technical Field

The utility model relates to a connector, wire rod, LED display screen technical field, specific theory has related to a female first pencil of formula of moulding plastics.

Background

In summary, the connection between the LED display screen and the power supply is mainly divided into a fixed assembly type and an air-docking type, and the main reasons why the air-docking type becomes a large component part include the following two aspects:

1. the cost can be reduced, after an original LED box body adopts a fixed installation mode, two sets of aviation plugs are needed, and an aerial butt joint mode is changed, one end of a wiring harness can be directly connected with a circuit board, and only one end of the wiring harness is connected through an aviation head, so that only one set of aviation head is needed;

2. install fast, the LED display screen is mostly rented the use temporarily in outdoor application, for example, hold the concert of singing, this just requires that the LED display screen can build fast, and the assembly can be accomplished to a pair of aviation head of aerial butt joint mode through the aerial operation of both hands, and the assembly can be accomplished to a pair of torsion, and fixed Assembly formula then need look for aviation socket's position, still can increase the installation degree of difficulty because of the space restriction.

Air butt joint, as the name suggests, just hang the aircraft nose aloft through the cable, based on this kind of butt joint demand, in the traditional connector selection type of LED display screen, can adopt NEUTRIK company's connector usually, but NEUTRIK company's connector is mostly based on fixed assembly mode design, and waterproof, lead to its structural more unnecessary structure that has, and because of there is always hidden danger in no waterproof design, need increase extra outer protecting product, if tie up isolated rainwater of modes such as sticky tape.

Some connectors with waterproof functions adopt brand-new sealing designs, but the corresponding scenes of the connectors far exceed the industrial requirements of the LED display screen, so that the manufacturing cost is too high, and the cost can be greatly increased when the connectors are applied to the field of LED display screens.

Based on the above problems, those skilled in the art need to modify the conventional aircraft head without waterproof design to obtain relatively good waterproof effect at low cost.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the not enough of prior art to a female first pencil of formula of moulding plastics that waterproof performance is good, low in manufacturing cost, be fit for butt joint in air is provided.

In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the utility model provides a female first pencil of formula of moulding plastics, includes female head, cable and the female first external mold of moulding plastics, female head includes cylindrical shell, is located the socket hole of cylindrical shell front end and is located the terminal of cylindrical shell rear end, the one end of cable is skinned the back and is connected on the terminal, the female first external mold of moulding plastics is for the parcel is in the cylindrical shell of female head and the colloid structure in the terminal outside, the tail end of the female head of moulding plastics sets up the screw thread section, install the screw thread lid in the screw thread section, the center of screw thread lid is provided with the through wires hole.

The female head is a structure formed by cutting a rectangular flange of a universal fixed assembly type aviation socket.

Basically, the female first external mold of moulding plastics is based on the integrative injection moulding structure of female first setting.

Basically, the surface one side of female first external mold of moulding plastics is provided with and aims at the boss.

Basically, the other side of the surface of the injection molding female head outer die is provided with a handshake boss.

Basically, the material of the injection molding female die and the injection molding outer die is PVC.

The type of the universal fixed assembly type aviation socket is one of NAC3MPA-1, NAC3MPB-1 and NAC3 MPX.

Basically, the threaded cover is selected from fittings on universal fixed assembly type aviation sockets with one of the models of NAC3MPA-1, NAC3MPB-1 and NAC3 MPX.

The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model discloses there is following advantage:

1. the cylindrical female head is adopted, the wiring terminal and the socket are configured, a flange structure for assembly is not arranged, then an injection molding female head outer mold is arranged on the outer layer, the tail end is provided with the thread and the thread cover, the product consistency is better, the hollow butt joint mode is completely adapted, the structure is free of waste, and the waterproof performance is good due to tight wrapping, and at least reaches IP65.

2. Because the female head is obtained after cutting off the rectangular flange based on traditional aviation socket, and the screw cap is also obtained from the accessory of traditional aviation socket, only need purchase an aviation socket aftertreatment processing of not taking waterproof function in the cost can, the high automation of injection molding process can further reduce cost when batch production for this product cost based on that traditional fixed assembled aviation socket transformation obtained reduces by a wide margin, more is fit for the use in LED display screen field.

3. An alignment boss and a handshake boss are arranged on the outer side of the injection molding female head outer mold and correspond to the corresponding structure box on the plug, and blind plugging operation in the air butt joint process is facilitated.

4. The cable is wrapped up in the screw thread section, and screw cap locking screw thread section, and then with cable locking, avoid the cable to break away from easily, promote product strength.
