Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to a piercing IDC wire-to-board connector. Background Technology

[0002] The piercing IDC wire-to-board connector is a precision component that enables rapid connection between cables and circuit boards without the need for wire stripping. It uses the sharp edge of the terminal to pierce the insulation layer and form an airtight contact with the conductor, combining high efficiency and reliability.

[0003] Due to its no-stripping process and simplified assembly procedure, piercing IDC can reduce costs by 30%-50% compared to traditional crimp connectors. With its advantages of no-stripping, low cost, high reliability, and easy installation, it has become the mainstream choice in industries such as industrial, automotive, and consumer electronics.

[0004] However, the puncture points of existing puncture-type IDC line-to-board connectors are prone to failure, resulting in unstable current transmission; and the complex structural design leads to low assembly efficiency. Summary of the Invention

[0005] Based on this, the purpose of this application is to provide a piercing wire-to-board connector, comprising: a housing and terminals housed in the housing, the terminals including a first conductive terminal, a second conductive terminal, and a connecting terminal for connecting the first conductive terminal and the second conductive terminal, the first conductive terminal and the second conductive terminal being housed in the housing for piercing the wires connected to the connector to achieve electrical connection, and the side of the connecting terminal not connected to the first conductive terminal and the second conductive terminal extending out of the housing for fixing to an external substrate.

[0006] Furthermore, the connecting end is fixedly connected to the first conductive end and the second conductive end by welding, and the side of the connecting end extending out of the outer side of the housing is flat and used to connect to the substrate.

[0007] Furthermore, the outer surface of the connecting end is flush with the end faces of the first conductive end and the second conductive end.

[0008] Furthermore, both the first conductive end and the second conductive end include a piercing section and a fixed section fixedly connected to the piercing section. The piercing section is used to pierce the wire of the connector to achieve electrical connection, and the fixed section is used to connect to the connection end. The end face of the fixed section away from the piercing section is flush with the outer surface of the connection end.

[0009] Furthermore, the piercing section includes a first cantilever and a second cantilever, which are spaced apart to form a piercing opening therebetween for piercing the wire.

[0010] Furthermore, the free ends of the first and second cantilever arms are provided with guide ramps to facilitate the insertion of guide wires into the puncture opening.

[0011] Furthermore, the fixed section includes a crossbeam, a third cantilever, and a fourth cantilever. One end of the crossbeam is connected to the first conductive end, and the other end is connected to the second conductive end. The third cantilever and the fourth cantilever are respectively fixed to one side of the crossbeam away from the first cantilever and the second cantilever, and are spaced apart to form a gap in the middle to accommodate the connecting end, so that the outer side of the connecting end is flush with the end faces of the third cantilever and the fourth cantilever.

[0012] Furthermore, the ends of the third cantilever and the fourth cantilever that are away from the first cantilever and the second cantilever are fixedly connected.

[0013] Furthermore, the outer side of the first cantilever, second cantilever, third cantilever, or fourth cantilever is provided with a protrusion for fixing to the housing.

[0014] Furthermore, the housing is provided with a plurality of parallel wire grooves for accommodating incoming wires. The plurality of wire grooves include a first accommodating through groove and a second accommodating through groove arranged in parallel. The directions of the first accommodating through groove and the second accommodating through groove are parallel to the directions of the wire grooves. The first conductive end and the second conductive end are respectively accommodated in the first accommodating through groove and the second accommodating through groove, and their ends extend out of the first conductive end and the second conductive end. The connecting end is fixedly connected to the first conductive end and the second conductive end and is located outside the housing.

[0015] The beneficial effects of this utility model are as follows: (1) By setting dual conducting terminals, when one conducting terminal fails, the other conducting terminal can continue to transmit current, improving the stability of current transmission. Furthermore, by connecting the first conducting terminal and the second conducting terminal, an integrated design is achieved, which is simple in structure, making assembly more convenient and saving assembly time. (2) The connector is miniaturized by setting the outer surface of the connection end to be flush with the end faces of the first and second conductive ends; (3) By providing protrusions on the outer sides of the first cantilever and the second cantilever or the third cantilever and the fourth cantilever, the terminals are more firmly fixed to the housing.

The terminals 12 include a first conductive end 121, a second conductive end 122, and a connecting end 123 for connecting the first conductive end 121 and the second conductive end 122. The first conductive end 121 and the second conductive end 122 are housed in the housing 11 and are used to pierce the wires connected to the connector to achieve electrical connection. The side of the connecting end 123 that is not connected to the first conductive end 121 and the second conductive end 122 extends out of the housing 11.

[0022] This application uses dual conducting terminals. When one conducting terminal fails, the other conducting terminal can continue to transmit current, improving the stability of current transmission. Furthermore, the first conducting terminal 121 and the second conducting terminal 122 are fixedly connected through the connecting terminal 123, realizing an integrated design with a simple structure, making assembly more convenient and saving assembly time.

[0023] In this embodiment, the connecting end 123 is fixedly connected to the first conductive end 121 and the second conductive end 122 by welding. The side of the welding surface extending outward from the outer side of the housing 11 is a plane for connecting to the plate end. In other embodiments, the connecting end 123 can be connected to the first conductive end 121 and the second conductive end 122 by bonding, snap-fitting, or other connection methods.

[0024] Furthermore, the outer surface of the connecting end 123 is flush with the end faces of the first conductive end 121 and the second conductive end 122 to achieve connector miniaturization.

[0025] Specifically, in this embodiment, both the first conductive end 121 and the second conductive end 122 include a piercing section 1211 and a fixing section 1212 fixedly connected to the piercing section 1211. The piercing section 1211 is used to pierce the wire of the connector to achieve electrical connection. The fixing section 1212 is used to connect to the connection end 123. The end face of the fixing section 1212 away from the piercing section 1211 is flush with the outer surface of the connection end 123.

[0026] Furthermore, the piercing section 1211 includes a first cantilever 12111 and a second cantilever 12112, which are spaced apart to form a piercing opening for piercing the wire. As a preferred embodiment, the free ends of the first cantilever 12111 and the second cantilever 12112 are provided with guide bevels to facilitate guiding the wire into the piercing opening.

[0027] Furthermore, the fixed section 1212 includes a crossbeam 12121, a third cantilever 12122, and a fourth cantilever 12123. One end of the crossbeam 12121 is connected to the first conductive end 121, and the other end is connected to the second conductive end 122. The third cantilever 12122 and the fourth cantilever 12123 are respectively fixed to one side of the crossbeam 12121 away from the first cantilever 12111 and the second cantilever 12112, and are spaced apart to form a gap in the middle to accommodate the connecting end 123, so that the outer surface of the connecting end 123 is flush with the end faces of the third cantilever 12122 and the fourth cantilever 12123.

[0028] Furthermore, the outer surfaces of the first cantilever 12111 and the second cantilever 12112 or the third cantilever 12122 and the fourth cantilever 12123 are provided with protrusions 124 for fixing to the housing 11.

[0029] In this embodiment, the housing 11 is a plastic housing 11.

[0030] Furthermore, the housing 11 is provided with a plurality of parallel wire grooves 111 for accommodating incoming wires. The plurality of wire grooves 111 include a first accommodating through groove 112 and a second accommodating through groove 113 arranged in parallel. The directions of the first accommodating through groove 112 and the second accommodating through groove 113 are parallel to the directions of the wire grooves 111. The first conductive end 121 and the second conductive end 122 are respectively accommodated in the first accommodating through groove 112 and the second accommodating through groove 113, and their ends extend out of the first conductive end 121 and the second conductive end 122. The connecting end 123 is fixedly connected to the first conductive end 121 and the second conductive end 122 and is located outside the housing 11.

[0031] Specifically, in this embodiment, the third cantilever 12122 and the fourth cantilever 12123 are fixedly connected after passing through the first receiving groove 112 and the second receiving groove 113. A gap is formed between two adjacent third cantilever 12122 and a gap is formed between two adjacent fourth cantilever 12123. The connecting end 123 body is accommodated in the gap, and its two sides are fixedly connected to the two third cantilever 12122 and the two fourth cantilever 12123 respectively.

[0032] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: (1) By setting dual conducting terminals, when one conducting terminal fails, the other conducting terminal can continue to transmit current, thereby improving the stability of current transmission. Furthermore, the first conducting terminal 121 and the second conducting terminal 122 are fixedly connected by the connecting terminal 123, achieving an integrated design with a simple structure, making assembly more convenient and saving assembly time. (2) By setting the outer surface of the connecting end 123 to be flush with the end faces of the first conductive end 121 and the second conductive end 122, the connector is miniaturized; (3) By providing protrusions 124 on the outer sides of the first cantilever 12111 and the second cantilever 12112 or the third cantilever 12122 and the fourth cantilever 12123, the terminal 12 is more firmly fixed to the housing 11.

[0033] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and the present invention also intends to include these modifications and variations.
