Description

Technical Field

[0001] This utility model relates to the technical field of double-row horizontal surface mount connectors, specifically a double-row horizontal surface mount connector. Background Technology

[0002] The horizontal surface mount pin assembly (hereinafter referred to as the pin assembly) consists of two parts: the pin assembly body and the suction cap. During the production process, the pin assembly is placed on the PCB by a pick-and-place machine, and then fixed on the PCB by reflow soldering. After assembly with other components, it forms a complete connector.

[0003] No effective solutions have yet been proposed to address the problems in the relevant technologies.

[0004] 1. When using existing double-row horizontal surface mount connectors, the inner conductor pin / hole dimensions are out of tolerance, resulting in excessive expansion (plastic deformation) or excessive gap (poor contact) during mating, loss of mating force, terminal mismatch failure, affecting connection stability. Moreover, during transportation, the terminals are impacted and bent, or the connector protection is insufficient, leading to assembly failures such as pin retraction and bent pins. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a double-row horizontal patch connector to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: A dual-row horizontal surface mount connector includes an LCP plastic base, bent pins, and an insulating pin channel. The bent pin array is disposed at the front end of the LCP plastic base, and the insulating pin channel array is fixedly connected to the front end of the bent pins. An insulating protective layer is provided on the outside of the insulating pin channel, and a snap-fit ​​plug is provided at the front end of the insulating pin channel.

[0007] A further improvement of this utility model is that the number of the insulating pin channels is six, and they are arranged in a linear array at the front end of the LCP plastic base.

[0008] By adopting the above technical solution, the insulated pin channel in the solution can provide insulation protection and mechanical support.

[0009] A further improvement of this utility model is that: the end of the insulated pin channel away from the snap-fit ​​plug is stamped into the interior of the LCP plastic base, the part inside the plastic is connected to the ribbon cable, and the part is soldered to the PCB board.

[0010] By adopting the above technical solution, the snap-fit ​​insertion and removal mechanism can enhance the stability of insertion and removal.

[0011] A further improvement of this utility model is that the snap-fit ​​insertion and removal is a self-locking snap-fit ​​structure.

[0012] A further improvement of this utility model is that the bent pins are arranged in two rows, and both rows of bent pins are arranged in a linear array at the front end of the LCP plastic base. The number of bent pins and the number and position of the insulating pin channels are matched.

[0013] Using the above technical solution, the bent pins are electroplated with a certain thickness of gold to increase their connectivity and corrosion resistance.

[0014] A further improvement of this utility model is that the lower row of bent pins is parallel to the bottom of the plastic, and the upper row of bent pins bends to the right and then downwards to be parallel to the bottom of the plastic.

[0015] The above technical solution uses an alternating arrangement of the upper and lower bent pins to avoid crosstalk.

[0016] The beneficial effects of this utility model are as follows: 1. By using LCP plastic material as the base, it meets the fire resistance rating UL94V0 and halogen-free requirements. The internally, there are precisely arranged insulated pin channels, which are protected by an insulating protective layer and mechanically supported. A snap-fit ​​plug-in is added to the top, which enhances the stability of plug-in and ensures that the terminals will not be skewed when impacted during transportation, and that there is no insufficient protection for the connectors. This reduces the probability of assembly failures such as pin retraction and pin skew.

[0017] 2. By stamping the bent leads into the plastic, and electroplating the bent leads with a certain thickness of gold, its connectivity and corrosion resistance are increased. The part inside the plastic connects to the ribbon cable, and the part is soldered to the PCB board. The lower row of bent leads is parallel to the bottom of the plastic, and the upper row of bent leads bends to the right and then downwards, parallel to the bottom of the plastic. The upper and lower bent leads are arranged alternately to avoid crosstalk. Attached Figure Description
