Description

Electrical contact quick connector

technical field

The utility model relates to the technical field of electrical connection components, in particular to a connection component for connecting electrical contacts in a power supply and distribution system and an information transmission system.

Background technique

The electrical contact is a twin that accompanies the generation of electricity and telecommunications. It increases with the expansion of the power distribution network and the increase of the electrical signal transmission network. It is the necessary passage for electricity or electrical signals to flow from one transmission line to another. For the power distribution network, the smaller the contact resistance of the electrical contact, the smaller the power loss; for the electrical signal transmission network, the smaller the contact resistance of the electrical contact, the smaller the signal attenuation; the most common The electrical contact is firstly the wire connection point of the household terminal in the power distribution network for the distribution and connection of various electrical power supply sockets for indoor life, and secondly the distribution and connection of the signal detection circuit and the drive and control circuit in the automatic control system .

For the electrical contacts in the power distribution network, it can be summarized into two forms according to the mechanical combination. One is to achieve good contact through the screw force of the terminal, and the other is to connect the wires that need to be electrically connected. Twisted together, using the tension generated by the wires twisted together and the secondary elasticity due to the existence of tension to achieve the purpose of good contact. Customarily, the latter is referred to as twisting, and the former is referred to as crimping. For the electrical signal transmission network, the electrical contacts in the network are basically made in the same way as the electrical contacts in the power distribution network, that is, except that the terminals of the wires have special extrusion forces generated by inelastic deformation to achieve good contact. Except for the purpose of jointing, it is customarily referred to as mortise joint for short, and the rest use spiral force and tension.

Screws or bolts and nuts are needed to make electrical contacts using screw force, and the contacts take up a lot of space. If there is a certain requirement for surface insulation, then when making electrical contacts, the insulating material that affects the good electrical contact should be removed first, and then After the screws or bolts are tightened, the surface needs to be insulated. Electricians usually use insulating tape or insulating tape to wrap the surface of the electrical contact just made to achieve the purpose of electrical insulation. The electrical contact made by tension needs to tightly twist the wires that need to be connected together, because the sum of the tension generated by the wires twisted together and the elastic force caused by this tension does not use the helical force So satisfactory, although the space occupied by the electrical contact produced by this connection method will be smaller, so as long as conditions permit, people will still consider using screw force to make electrical contacts.

For the electrical connection points made at the ends of the wires, although there are special terminal connection devices that rely on the extrusion force generated by inelastic deformation to achieve good contact, these special devices can only make electrical contacts at the terminals, such as telecommunications Connecting devices used to extend telephone lines in the field of computer applications, RJ45 crystal plugs used to connect to LANs in the field of computer applications. Although these similar terminal connection devices can quickly produce electrical contacts with a certain insulation strength on the surface, they can only be used at the ends of the wires, and are not suitable for making electrical contacts in the middle of the wires to tap electrical signals.

Utility model content

The purpose of the utility model is to provide a quick connector for electrical contacts, which can solve the problem that the existing connectors can only make electrical contacts at the ends of wires, and improve the speed of making electrical contacts.

In order to solve the above problems, the technical solution adopted by the utility model is: this kind of electrical contact quick connector includes a belt body that surrounds at least two cables and a conductive connector that fastens the belt body, and the cable conduction through the conductive plug.

In the above technical solution of the electrical contact quick connector, a more specific technical solution may also be: at least one end of the conductive insert is a cone or a truncated cone.

Further, the conductive plug is a rigid conductive plug with at least one insertion portion, and the insertion portion is directly inserted into the cable and directly contacts the conductor of the cable.

Further, the conductive plug is an elastic conductive plug with at least one insertion portion, and the ends of the insertion portion are bent against each other through a wedge or by itself.

Further, the belt body is provided with an insertion hole for inserting the connector.

Further, a plurality of the jacks are correspondingly opened in the overlapped portion of the belt body.

Further, the surface of the belt is provided with a groove, the insertion hole is opened in the groove, and the belt is provided with a protective cover covering the groove.

Further, the inner surface of the belt is roughened or provided with protrusions.

Further, barbs are arranged on the surface of the conductive plug.

Further, the strap body is a strapping strap with a buckle at one end, and the strapping strap is provided with a plurality of through holes.

Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

1. Use the belt body to surround the cable, and insert the connector to fasten the belt body and conduct the cable, so that electrical contacts can be quickly made at any position of the cable.

2. The end of the conductive connector is a cone or truncated cone, which is conducive to quick insertion; the rigid connector can be quickly inserted without auxiliary tools; the structure of the elastic connector can obtain a good electrical contact effect .

3. Corresponding jacks are set in the overlapping parts of the belt body, which is conducive to quick positioning and makes the belt body more stable; when it is applied to insulated wires, the jacks are opened in the groove, and the protective cover is set. It can make the connector not exposed, so as to ensure that the electrical contact is also insulated from the conductor.

4. The inner surface of the belt body is rough or provided with protrusions, which can increase the friction between the belt body and the cable, so that the belt body can be tightly occluded with the surface of the cable, and finally increase the pull-out resistance off the ability.

5. The conductive connector is equipped with barbs, which can make it easy to enter and difficult to exit, so as to prevent the connector from slipping off; the strap body is designed as a strapping strap with a lock, which can directly tighten the cable.

6. There is very little damage to the insulating protective layer of the insulated wire, and basically the environmental state in which the insulating protective layer isolates the conductor from the air can still be maintained, so that the anti-oxidation ability of the wire remains unchanged.

7. The space occupied by electrical contacts is not large, which is basically the same as or even smaller than the "twisted contacts" twisted together.

8. In the field of signal detection, it is convenient for electrical state sampling or long-term online detection of electrical signal detection points.

9. For the outdoor hanging power distribution system and electrical signal transmission and detection system using non-insulated wires or bare wires, when making electrical contacts, the utility model can obtain faster than "twisting" or "joint". Faster production speed and stronger reliability.
