Description

Block Type Connector Assembly for Vehicles

The present invention relates to a block type connector assembly for a vehicle. In more detail, the cavity plugs adjacent to each other are slidably coupled to each other so that the assembly plugs are easy to assemble, and the cavity plug module is slidably coupled to the socket plug and is firmly fixed to prevent mutual play. In this case, it is related to a block-type connector assembly for a vehicle, which can be prevented from being inserted into a block, thereby preventing malfunction of the electronic device.

In general, a connector is a connecting part used to electrically connect one circuit to another circuit. In a vehicle, a connector is used to connect or connect a cable or a wire.

In recent years, the number of electrical appliances mounted on a vehicle is increasing very much for the convenience of the user. Accordingly, the number of cables or wires required increases, so that various connectors are used to connect or connect them.

1 is a conceptual diagram conceptually showing a circuit connection state of a general connector mounted on a vehicle.

As shown in (a) of FIG. 1, when the number of electrical appliances 20 mounted on a vehicle is limited, a joint connector 10 is generally used, and a cable is connected from one power source 10 so that the joint connector ( 10), separated by a plurality of wires from the joint connector 10, power is supplied to the various electrical appliances 20, and is configured in such a way that they are integrated into one joint connector 10 '.

On the contrary, in recent years, the number of electronic devices 20 rapidly increases according to the trend of high-end electronics, in which the joint connector 10 is integrated into one instead of the circuit structure of the joint connector 10 shown in FIG. The block type connector 30 of the form is used.

FIG. 2 is an exploded perspective view briefly illustrating a conventional block type connector assembly for a vehicle according to the prior art, and FIG. 3 is a cross-sectional view taken along the line “A-A” of FIG. 2.

As shown in FIG. 2, the block-type connector assembly includes a plurality of terminals 31, a cavity plug module 32 to which at least two or more cavity plugs 32 ′ into which the plurality of terminals 31 are inserted are coupled; The socket plug 33 into which the cavity plug module 32 is inserted, the block 33 into which the socket plug 33 is inserted, and the block to be connected to the terminal 31 as the socket plug 33 is inserted into the block It consists of a PCB (35) coupled to (33).

In general, as shown in FIG. 2, ten terminals 31 are inserted into the cavity plug 32 ′, and a plurality of such cavity plugs 32 ′ are arranged in parallel such that adjacent cavity plugs 32 ′ are adjacent to each other. Combining to form a cavity plug module 32 is inserted into the socket plug (33).

Since the locking protrusion 32b and the locking groove 32c are coupled in a fitting manner, they are easily separated by external loads, and also loosely coupled by deformation, so that adjacent cavity plugs 32 'are easily separated from each other, thereby assembling work. This was not an easy problem. In addition, when the cavity plug module 32 is inserted into the socket plug 33, the cavity plug module 32 is inserted into the socket plug 32 by the guide protrusion 32a and the guide groove 33a. Since there is no means for fixing to prevent the separation from 33, there is a problem that the entire cavity plug module 32 is easily separated from the socket plug 33. In addition, even if the order of the cavity plug 32 'is arranged differently, since it can be inserted into the socket plug 33 and finally inserted into the block 33, various electrical components may malfunction due to an incorrect circuit configuration. There was a problem.

Therefore, the present invention has been invented to solve this problem, the cavity plugs adjacent to each other sliding coupling and do not deviate from each other to facilitate the assembly work, the cavity plug module is slidingly coupled to the socket plug and does not generate mutual clearance. The object of the present invention is to provide a block connector assembly for a vehicle that is firmly fixed and prevented from malfunctioning of electrical appliances by preventing the insertion of a cavity plug into a block when the cavity plug is misaligned.
