Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention can be embodied in many different forms other than those specifically described herein, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the invention, and it is therefore not to be limited to the specific embodiments disclosed below.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-6, the utility model discloses a high pressure resistant heavy current three lead to cable connector, including casing 1, be equipped with cable core 2 in this casing, cable core 2 includes 3, and the wire wherein passes through circuit board 3 in the casing 1 and connects.

As shown in fig. 1-6, a plurality of copper foils 31 are disposed on the circuit board 3, through holes 33 are disposed between adjacent copper foils 31, and two conductive copper pillars 32 are disposed in the area covered by each copper foil 31, wherein the conductive copper pillars 32 penetrate through the circuit board 3. The through hole 33 isolates the adjacent lines, and even if the voltage or the current is high, short circuit caused by line conduction does not occur, so that the safety of the connector is improved.

As shown in fig. 1 to 6, the three-way cable connector includes a first cable 21, a second cable 22, and a third cable 23, and on one surface of the circuit board 3, the conductive wires of the first cable 21 and the conductive wires of the second cable 22 are soldered to one ends of two conductive copper posts 32, respectively, and on the other surface of the circuit board 3, the conductive wires of the third cable 23 are soldered to the other ends of the conductive copper posts 32. Welding the wire on the conductive copper post 32 can prevent welding slag from splashing and facilitate welding. The penetrating conductive copper pillar 32 can enable the two sides of the lead to be welded, and the connection mode can enable the wiring structure to be more reasonable.

While the foregoing description shows and describes several preferred embodiments of the invention, it is to be understood, as noted above, that the invention is not limited to the forms disclosed herein, but is not intended to be exhaustive or to exclude other embodiments and may be used in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.
