Description

Branching connector

[ technical field ] A method for producing a semiconductor device

The utility model relates to a branch line connector, in particular to tee bend connector.

[ background of the invention ]

When a plurality of LED lamps or a plurality of groups of LED lamps need to be connected, a three-way connector is used for electrical connection. Some three-way connectors on the existing market are formed by one-time injection molding, but because of the wires and the circuits, materials with high melting points cannot be used, so that the strength of the connectors is not high. Some of the market is manufactured by glue injection, which includes a housing having a cavity and three wire outlets, a wire is placed in the cavity, a circuit board is provided on the wire, glue is injected into the housing, the wire and the circuit are fixed, and then a cover is covered on the housing.

[ Utility model ] content

The utility model aims at overcoming the not enough of prior art, provide a simple structure, bilayer structure's branch line connector.

In order to solve the problem, the utility model adopts the following technical scheme:

the utility model provides a branch line connector, is including the inner core of parcel electric wire, the both ends of inner core be equipped with the end that supplies main electric wire to stretch out, its characterized in that: the side surface of the inner core is provided with a convex column for extending the distribution wire, the outer side of the inner core is wrapped by the outer shell, the end heads extend out of two ends of the outer shell, and the convex column extends out of the side surface of the outer shell.

A branching connector as described above, characterized in that: the side surface of the shell is provided with a mounting hole, and the inner core is provided with a clearance gap below the mounting hole.

A branching connector as described above, characterized in that: the mounting holes are two, and the two mounting holes are respectively arranged on the left side and the right side of the shell and are respectively close to the two ends.

A branching connector as described above, characterized in that: the inner core and the end head are wrapped on the electric wire through integral injection molding, and the shell is wrapped outside the inner core through injection molding.

A branching connector as described above, characterized in that: the edge of the end face of the end head extends out of the inner core, and two ends of the shell are abutted against the end face of the end head.

The beneficial effects of the utility model are that: the inner core is provided with the convex column which protrudes out of the shell, so that the shell is convenient to position during injection molding, and the wire can be extended out at the same time, so that the structure is simple, the inner core can be made of a material with a slightly lower melting point to protect the wire and the circuit board, and the shell can be made of a material with a higher melting point to provide hardness and waterproof performance; through setting up the mounting hole on the shell, set up on the inner core and keep away the gap, the shell is moulding plastics the back, and the shell material fills and keeps away the gap, keeps away the intraoral material of gap like this and also is the shell material, through the screw installation back, improves installation strength.

[ detailed description ] embodiments

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 1 to 2, a branch connector includes an inner core 1 for enclosing an electric wire including a wire, a circuit board, etc. The two ends of the inner core 1 are provided with end heads 2 for extending out of the main wire, the end heads 2 and the inner core 1 are integrally formed, the inner core 1 is in a long strip shape, one side of the end heads 2 of the inner core 1 is a square end, the size of the square end is larger than that of the inner core 1, and the edge of the square end extends out of the inner core 1 from the side face. Be equipped with the projection 3 that supplies to divide the pencil to stretch out on the side of inner core 1, projection 3 establishes the middle part in the side of inner core 1, through setting up projection 3 and conveniently when moulding plastics the second time, mould plastics shell 4 promptly, makes things convenient for the location of inner core 1, makes things convenient for shell 4 to mould plastics the parcel, and 3 supplies to divide the pencil to stretch out simultaneously. The inner core 1 is wrapped by the outer shell 4, the end heads 2 extend out from two ends of the outer shell 4, the convex column 3 extends out from the side face of the outer shell 4, and the branch line extends out from the convex column 3 and is used for being externally connected with other connectors. The side surface of the shell 4 is provided with a mounting hole 41, and a clearance gap 11 is arranged below the mounting hole 41 on the inner core 1. Two mounting holes 41 are arranged, the two mounting holes 41 are respectively arranged at the left side and the right side of the shell 4 and are respectively close to the two ends 2, and when screws are installed, the screws penetrate through the mounting holes 41 and the injection molding materials of the shell 4 in the clearance gap 11, so that the inner core 1 and the shell 4 are connected more firmly. The two ends of the shell 4 are propped against the end surface of the end head 2, and the shell 4 is firmly positioned and cannot fall off. The inner core 1 and the end 2 are wrapped on the electric wire through integral injection molding, and the shell 4 is wrapped outside the inner core 1 through injection molding.
