Description

Technical Field

[0001] The present invention relates to the technical field of circuit connection, and in particular to a straddling multi-core printed circuit connector. Background Art

[0002] Printed circuit connectors are primarily used to transmit circuits between printed circuit boards, connecting or disconnecting circuits. The current trend toward miniaturization and lightweighting of weaponry and other equipment requires printed circuit connectors that can transmit multiple signals while minimizing the space required for installation.

[0003] like Figure 10 As shown, the disadvantages of the prior art are: 1. The output terminal of the printed circuit connector is soldered to the printed circuit board. When soldered to the printed circuit board, the output terminal pins are all located on the same side, leaving the back of the printed circuit board unusable. As a result, the printed circuit board's surface area is low. 2. The node size (i.e., spacing) between the pins on the output terminal of a conventional printed circuit connector remains consistent. That is, the output terminal (the part where the plug connects to the printed circuit board) and the printed circuit board soldering area occupy the same printed circuit board area as the socket terminal, resulting in a larger size and heavier connected printed circuit board.

[0004] In summary, existing technical solutions are difficult to meet the requirements of transmitting multiple signals while ensuring use in environments with limited installation space. For occasions with limited installation space, conventional printed circuit connectors cannot meet the requirements of installation and use. Summary of the Invention

[0005] The main purpose of the present invention is to provide a straddle-type multi-core printed circuit connector, aiming to solve the existing technical problems.

[0006] To achieve the above-mentioned object, the present invention provides a straddle-type multi-core printed circuit connector for electrical connection of a printed circuit board, comprising:

[0007] An insulating body, provided with a card slot, wherein a socket is provided in the card slot;

[0008] The contact pieces include contact piece 1, contact piece 2, contact piece 3, contact piece 4 and contact piece 5. The contact piece 1, contact piece 2, contact piece 3, contact piece 4 and contact piece 5 are distributed on both sides of the printed circuit board in a straddling manner.

[0009] Furthermore, the ends of the contact piece 1 and the contact piece 2 abut against the first side of the printed circuit board, and the ends of the contact piece 3, the contact piece 4 and the contact piece 5 abut against the second side of the printed circuit board.

[0010] Furthermore, the contact member includes a contact portion inserted into the socket, a bent portion extending outward from an end portion of the contact portion, and a soldering portion extending outward from the bent portion and elastically resting against the first side of the printed circuit board.

[0014] The third end of the welding portion of the third contact piece is spaced apart from the first contact piece and the second contact piece and is symmetrically distributed with respect to the contact position of the printed circuit board.

[0015] Furthermore, the contact member 4 includes a contact portion 4 inserted into the insertion hole, a bent portion 4 extending outward from an end portion of the contact portion 4, and a soldering portion 4 extending outward from the bent portion 4 and elastically resting against the second side of the printed circuit board;

[0016] Among them, the contact piece four and the contact piece three are arranged in different rows and staggered, and the welding portion four of the contact piece four is inclined toward the welding portion three of the contact piece three, and the end of the welding portion four of the contact piece four is coplanar with the end of the welding portion of the contact piece three.

[0017] Furthermore, the contact member 5 includes a contact portion 5 inserted into the insertion hole, a bent portion 5 extending outward from an end of the contact portion 5, and a soldering portion 5 extending outward from the bent portion 5 and elastically resting against the second side of the printed circuit board;

[0018] Among them, the contact member five and the contact member four are arranged in different rows and staggered, and the welding portion five of the contact member five is arranged in parallel with the welding portion four of the contact member four, and the contact part between the welding portion of the contact member five and the printed circuit board is higher than the contact part between the contact member three or the contact member four and the printed circuit board.

[0019] Furthermore, the first contact member and the second contact member are in alternating and side-by-side contact with the first side of the printed circuit board.

[0020] Furthermore, the contact member 3 and the contact member 4 are in alternating side-by-side contact with the second side of the printed circuit board, the contact member 5 is in equidistant contact with the second side of the printed circuit board, and the space between adjacent contact members 5 is one contact member.

[0021] Furthermore, the contact piece 1, the contact piece 2, the contact piece 3, the contact piece 4 and the contact piece 5 are all made by stamping.

[0022] The beneficial effects of the present invention are embodied in:

[0023] The present invention realizes a novel "riding-type" printed circuit connector structure through the structural design of the contact piece.

[0024] The present invention transforms the multi-row (five-row) pin input end of the printed circuit connector into a two-row pin output end structure, straddling both sides of the connected printed circuit board. This fully utilizes the space on both sides of the printed circuit board, reduces the number of pads on a single-sided printed circuit board, and thus reduces the overall size of the printed circuit board.

[0048] Specifically, the end of the third soldering portion 403 of the third contact 400 is spaced apart from the first contact 200 and the second contact 300 and the contact position with the printed circuit board A is symmetrically distributed.

[0049] See also Figure 6 The contact member 500 includes a contact portion 501 inserted into the socket 101, a bent portion 502 extending outward from the end of the contact portion 501, and a soldering portion 503 extending outward from the bent portion 502 and elastically resting against the second side of the printed circuit board A.

[0050] Specifically, contact piece four 500 and contact piece three 400 are arranged in different rows and staggered, and welding portion four 503 of contact piece four 500 is tilted toward welding portion three 403 of contact piece three 400, and the end of welding portion four 503 of contact piece four 500 is coplanar with the end of welding portion of contact piece three 400.

The contact part between the welding portion of contact piece five 600 and printed circuit board A is higher than the contact part between contact piece three 400 or contact piece four 500 and printed circuit board A.

[0053] The first contact member 200 and the second contact member 300 are in contact with the first side of the printed circuit board A in an alternating manner and in parallel.

[0054] The third contact member 400 and the fourth contact member 500 are in alternating and side-by-side contact with the second side of the printed circuit board A.

[0055] The first contact piece 200 , the second contact piece 300 , the third contact piece 400 , the fourth contact piece 500 and the fifth contact piece 600 are all made by stamping.

[0056] This invention designs a straddling printed circuit connector. This design transforms the multi-row (five-row) pins at the input end of the connector into a two-row pin output structure that straddles the connected printed circuit board. By utilizing the soldering space on the front and back of the printed circuit board, the output node size is reduced, thereby reducing the connector's overall dimensions. This enables multi-channel signal transmission while ensuring the connector's limited installation space.

[0057] The "straddle" printed circuit connector structure is primarily achieved through the structural design of the contacts. The printed circuit connector has 256 cores, and the contacts are arranged in five rows. To achieve this "straddle" structure, we designed five different contact sizes.

[0058] The contacts are stamped. Through two bending angles, the two rows of contacts on the left are extended and bent (with different shapes) and then aligned in a single row. The three rows of contacts on the right are extended and bent (with different shapes) and then aligned in two rows for soldering to the printed circuit board. The tail design of the contacts originally required five rows of solder joints. The special-shaped bending design of the contact pins reduces the number of rows required for soldering to the printed circuit board to only three rows, fully utilizing the space available on the printed circuit board. Furthermore, the three rows of solder joints on the pin ends are distributed on both sides of the printed circuit board, with the connector pins straddling the two sides like a horse. This unique structure reduces the pad space on the printed circuit board and improves the board's surface area.

[0059] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0060] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes in which A and B are satisfied at the same time. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist.

[0061] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
