Description

Technical Field

[0001] This utility model relates to the field of electronic components technology, and in particular to a 90° multi-pin same-side connector. Background Technology

[0002] A pin connector is a metallic component used in connectors primarily for electrical conductivity. Pins act as bridges within the connector, connecting blocked or isolated circuits to ensure the smooth transmission of current or signals.

[0003] Currently in the connector industry, multi-pin bent connector pins mainly rely on plastic retaining blocks at the pin tails for limiting their position after bending. However, even after bending and assembling the retaining blocks, some pins still exhibit inconsistent heights. Since connector pins are formed by a second bending after molding, plastic retaining blocks need to be installed at the connector pin soldering plate to fix them in place and ensure the reliability of the product soldering.

[0004] When the product is injection molded and then bent twice before the fixing block is installed, the existing pins have no limit on the locking points. The pins are under great stress, and the fixing block holes are large. Under the influence of the two, the pins will move, resulting in pins of different heights. Therefore, it is necessary to add limiting points to the pins to increase the holding force between the pins and the plastic baffle. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a 90° multi-pin same-face connector.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A 90° multi-pin same-sided connector includes a housing. Signal pin mounting portions and overcurrent pin mounting portions are arranged on the housing in a left-right distribution. Multiple signal pins are evenly distributed and inserted on the signal pin mounting portions, and multiple overcurrent pins are evenly distributed and inserted on the overcurrent pin mounting portions. Limiting slots and positioning slots are formed on the two side plates of one side surface of the housing. A plastic fixing block is horizontally fixed between the limiting slots on both sides. The plastic fixing block is used to fix the other end of the signal pins and overcurrent pins away from the signal pin mounting portions and overcurrent pin mounting portions, respectively.

[0008] In addition, a preferred structure is that a connection port is provided on the surface of the outer shell away from the limiting slot and on the outer periphery of the signal PIN mounting part and the overcurrent PIN mounting part, and a silicone sealing ring is affixed to the outer periphery of the connection port.

[0009] In addition, a preferred structure is that nut mounting holes are provided at the four corners of the outer periphery of the outer shell, and knurled nuts are installed at the nut mounting holes.

[0010] In addition, a preferred structure is that the plastic fixing block is provided with a plurality of first connection holes and second connection holes for installing signal PIN pins and overcurrent PIN pins in a left-right arrangement. The first connection hole is provided with a first conical limiting hole and the second connection hole is provided with a second conical limiting hole.

[0011] In addition, a preferred structure is that limit feet are symmetrically and vertically arranged on both side walls of the plastic fixing block, and a positioning block is vertically arranged on one side of each limit foot. The limit feet are used to lock into the limit groove, and the positioning blocks are used to fit into the positioning groove.

[0012] Furthermore, in a preferred configuration, a first limiting portion is provided at the bottom middle section of the signal PIN pin, the first limiting portion being used to engage with the signal PIN pin mounting portion, and a first limiting head is provided at the top of the signal PIN pin, the first limiting head being installed at the first connecting hole and engaged with the first conical limiting hole.

[0013] Furthermore, in a preferred configuration, a second limiting portion is provided at the bottom middle section of the overcurrent PIN pin, which is used to lock onto the overcurrent PIN pin mounting portion. A second limiting head is provided at the top of the overcurrent PIN pin, which is installed at the second connecting hole and locked onto the second conical limiting hole.

[0014] The beneficial effects of this invention are as follows: By setting a first limiting head and a first limiting part on the signal PIN pin, and a second limiting head and a second limiting part on the overcurrent PIN pin, and correspondingly setting a first tapered limiting hole and a second tapered limiting hole on the plastic fixing block, precise positioning of both ends of the PIN pin is achieved. This significantly increases the holding force between the PIN pin and the plastic fixing block, effectively overcoming the warping or displacement caused by stress release after bending the PIN pin, ensuring that the soldering end of all PIN pins, i.e., the end held by the plastic fixing block, can remain on the same plane, completely eliminating the "high and low pin" phenomenon, and greatly improving the reliability and yield rate when the product is soldered to the circuit board.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-10 A 90° multi-pin same-side connector includes a housing 1. Signal pin mounting portions 13 and overcurrent pin mounting portions 14 are arranged on the housing 1 in a left-right distribution. Multiple signal pins 3 are evenly distributed and inserted on the signal pin mounting portions 13, and multiple overcurrent pins 4 are evenly distributed and inserted on the overcurrent pin mounting portions 14. Limiting slots 15 and positioning slots 16 are formed on the two side plates of one side surface of the housing 1. A plastic fixing block 2 is horizontally fixed between the limiting slots 15 on both sides. The plastic fixing block 2 is used to fix the other end of the signal pins 3 and overcurrent pins 4 away from the signal pin mounting portions 13 and overcurrent pin mounting portions 14.

[0028] Among them, a connection port 11 is provided on the side surface of the outer shell 1 away from the limiting slot 15 and on the outer periphery of the signal PIN mounting part 13 and the overcurrent PIN mounting part 14. A silicone sealing ring 6 is attached to the outer periphery of the connection port 11 to increase the sealing performance.

[0029] In addition, nut mounting holes 12 are provided at the four corners of the outer periphery of the outer casing 1, and knurled nuts 5 are installed at the nut mounting holes 12.

[0030] Meanwhile, the plastic fixing block 2 is provided with multiple first connecting holes 24 and second connecting holes 25 arranged in a left-right pattern for installing signal PIN pins 3 and overcurrent PIN pins 4. The first connecting hole 24 is provided with a first conical limiting hole 23, and the second connecting hole 26 is provided with a second conical limiting hole 25. The first conical limiting hole 23 and the second conical limiting hole 25 can better hold the signal PIN pin 3 and overcurrent PIN pin 4 in place.

[0031] In addition, symmetrically vertically arranged limit feet 21 are provided on both sides of the plastic fixing block 2, and a positioning block 22 is vertically arranged on one side of each limit foot 21. The limit foot 21 is used to be locked in the limit groove 15, and the positioning block 22 is used to be adapted to the positioning groove 16.

[0032] Furthermore, a first limiting part 32 is provided at the bottom middle section of the signal PIN pin, which is used to lock onto the signal PIN pin mounting part 13. A first limiting head 31 is provided at the top of the signal PIN pin 3, which is installed at the first connecting hole 24 and locked onto the first conical limiting hole 23. The first limiting head 31 increases the holding force of the plastic fixing block 2. A second limiting part 42 is provided at the bottom middle section of the overcurrent PIN pin 4, which is used to lock onto the overcurrent PIN pin mounting part. At point 14, a second limiting head 41 is provided on the top of the overcurrent PIN pin 4. The second limiting head 41 is installed at the second connecting hole 26 and is locked on the second conical limiting hole 25. The barbs and positioning steps provided on the first limiting head 31 and the second limiting head 41 are intended to limit the up and down floating position of the pins at the top of the first limiting head 31 and the second limiting head 41, ensuring that the heads of the first limiting head 31 and the second limiting head 41 are on the same plane, and eliminating the problem of inconsistent pin height caused by stress after bending of the copper material.

[0033] In this embodiment, the first limiting part 32 and the second limiting part 42 of the signal PIN pin 3 and the overcurrent PIN pin are respectively locked on the signal PIN pin mounting part 13 and the overcurrent PIN pin mounting part 14. Then, the barbs and positioning steps of the first limiting head 31 are locked on the first connecting hole 24 and the first conical limiting hole 23, and the barbs and positioning steps of the second limiting head 41 are locked on the second connecting hole 26 and the second conical limiting hole 25.

[0034] In this invention, by providing a first limiting head 31 and a first limiting part 32 on the signal PIN pin 3, and a second limiting head 41 and a second limiting part 42 on the overcurrent PIN pin 4, and correspondingly providing a first conical limiting hole 23 and a second conical limiting hole 25 on the plastic fixing block 2, precise positioning of both ends of the PIN pin is achieved. This significantly increases the holding force between the PIN pin and the plastic fixing block 2, effectively overcoming the warping or displacement caused by stress release after bending the PIN pin, ensuring that the soldering ends of all PIN pins, i.e., the ends held by the plastic fixing block, can remain on the same plane, completely eliminating the "high and low pin" phenomenon, and greatly improving the reliability and yield rate when the product is soldered to the circuit board.
