[0033] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] See also Figure 1-8 As shown, the present invention discloses an application system for a board-mounted parallel connector, including an onboard parallel connector 300, which is electrically connected to a device (not shown) to input current or signals into the device or output current or signals from the device. The onboard parallel connector 300 is mounted on the device housing, with one end extending into the device. Multiple conductive wires (not shown) are connected to the device, and these wires need to be connected in parallel before being electrically connected to the electronic components within the device. Electrically connecting the onboard parallel connector 300 to the multiple conductive wires enables parallel connection of these wires. The onboard parallel connector 300 enables parallel connection of multiple conductive wires outside the device. In other words, the onboard parallel connector 300 replaces the need for mounting multiple sets of conventional connectors on the housing that can only connect to one conductive wire. Furthermore, the multiple conductive wires used to connect to multiple conventional connectors do not need to be connected in parallel within the device. The onboard parallel connector 300 of the present invention reduces the space occupied by the connector on the device, facilitates connector wiring, and reduces overall cost.

[0035] The onboard parallel connector 300 includes a male parallel connector 100 and a female parallel connector 200. At most one set of the male parallel connector 100 and the female parallel connector 200 is installed on the housing of the device. This is used to input current or signals into the device, or to output current or signals inside the device. In other words, only at most two interfaces need to be reserved on the housing for installing one or a combination of the male parallel connector 100 and the female parallel connector 200. The onboard parallel connector 300 can save space inside the device, reduce the size of the device, and save costs.

[0036] This technical solution can be used for both the male-end parallel connector 100 and the female-end parallel connector 200 . For the convenience of description, the following description uses the male-end parallel connector 100 as an example.

[0037] The male end parallel connector 100 includes a rubber core 1, a conductive terminal 2 accommodated in the rubber core 1, and a wiring terminal 3 mounted on the rubber core 1 and electrically connected to the conductive terminal 2. The wiring terminal 3 is used to connect to the plurality of conductive wires. Specifically, a plurality of wiring slots 31 for inserting the conductive wires are provided on the side of the wiring terminal 3 away from the conductive terminal 2, so that the plurality of conductive wires are electrically connected to the conductive terminal 2, and the plurality of conductive wires are connected in parallel. Figure 4 As shown, in this embodiment, the wiring slots 31 are preferably provided with three. Of course, in other optional embodiments, the wiring slots 31 can also be provided with two, four, etc. according to actual needs, as long as multiple conductive wires inserted in the corresponding wiring slots 31 can be connected in parallel, without limitation.

[0038] Combine Figure 4 and Figure 5 As shown, the connection terminal 3 includes an integrally formed connection terminal 32 and a connecting terminal 33. The connection slot 31 is located in the connection terminal 32, and the connecting terminal 33 extends toward the conductive terminal 2 to connect with the conductive terminal 2. In this embodiment, both the connection terminal 32 and the connecting terminal 33 are cylindrical, and the radius of the connection terminal 32 is larger than that of the connecting terminal 33. Of course, in other optional embodiments, the connection terminal 32 and the connecting terminal 33 may also be configured in other shapes, which are not limited to comparison.

[0039] The outer periphery of the wiring terminal 3 is provided with a plurality of limiting holes 34 connected to the wiring groove 31, and the limiting holes 34 are used for the wire locking member 4 to penetrate and squeeze the conductive wire to fix the conductive wire. Specifically, the limiting hole 34 is opened at the wiring terminal 32, and the opening directions of the wiring groove 31 and the limiting hole 34 are preferably arranged perpendicular to each other. The outer periphery of the wire locking member 4 is provided with an external thread, and the inner periphery of the limiting hole 34 is correspondingly provided with an internal thread. The wire locking member 4 is screwed into the limiting hole 34 and is tightly connected with the limiting hole 34, and extends into the wiring groove 31 to squeeze the conductive wire. In this embodiment, the wiring terminal 3 and the wire locking member 4 are both made of metal and have good conductivity.

[0040] The side of the connecting terminal 3 facing the conductive terminal 2 is provided with a connection slot 35 for inserting the conductive terminal 2, thereby securing the conductive terminal 2 with the conductive terminal 2. Specifically, the connection slot 35 is provided at the connecting end 33. In other optional embodiments, the conductive terminal 2 and the connecting terminal 3 can be integrally formed, which is not limited thereto.

[0041] Combine Figure 2-Figure 3 and Figure 6-Figure 7 As shown, the conductive terminal 2 is a male terminal, and the rubber core 1 corresponds to a male end rubber core. The rubber core 1 is provided with an integrally formed mounting end 11 and a plug-in end 12, and the wiring terminal 3 is assembled on the mounting end 11 of the rubber core 1. The mounting end 11 is provided with a receiving cavity 111 for receiving the wiring terminal 3, and the wiring terminal 3 is partially exposed in the receiving cavity 111. Specifically, the limiting hole 34 is exposed in the receiving cavity 111 to facilitate the insertion of the locking wire member 4. A step portion 112 is provided on the inner peripheral wall of the receiving cavity 111, and a matching portion 321 is correspondingly provided on the wiring terminal 32 of the wiring terminal 3. The matching portion 321 is arranged on the side of the wiring terminal 32 facing the connecting end 33, and the matching portion 321 abuts against the step portion 112 to limit the wiring terminal 3. The plug end 12 is used for snap-fit ​​connection with a corresponding connector. The plug end 12 is provided with a plug cavity 121 that communicates with the receiving cavity 111. The conductive terminal 2 is located in the plug cavity 121 and is spaced apart from the inner wall of the plug cavity 121. The plug cavity 121 can increase the mechanical connection strength.

[0042] The male parallel connector 100 also includes a housing 5 mounted on the outside of the terminal block 3, which is snap-fitted to the mounting end 11. Specifically, the mounting end 11 is provided with a protruding fastener 113, and the housing 5 has a corresponding fastening groove 51. The fastener 113 extends into the fastening groove 51, securing the housing 5 to the rubber core 1. The outer wall of the mounting end 11 is also provided with a groove 114 for accommodating a sealing ring 6. The sealing ring 6 is connected between the rubber core 1 and the housing 5, providing a seal to prevent water and dust from entering the device.

[0043] The male-end parallel connector 100 also includes a plug 7 and a wire lock nut 8. The plug 7 is housed within the end of the housing 5 away from the conductive terminal 2. The plug 7 is provided with a plurality of through-holes 71 for the conductive wires to pass through. The wire lock nut 8 is disposed outside the plug 7 and is threadedly connected to the housing 5. In this embodiment, the housing 5 is connected to the housing of the device, and the plug 7 and wire lock nut 8 are located within the device. The plug 7 is spaced apart from the terminal 3 to arrange the conductive wires, and the wire lock nut 8 is used to retain the plug 7 within the housing 5.

[0044] like Figure 1 and Figure 8 As shown, when the board-mounted parallel connector 300 in this technical solution is a female parallel connector 200, the only difference is that the plug-in end 12 of the rubber core 1 and the conductive terminal 2 are different, and the other structures are the same. The conductive terminal 2 in the female parallel connector 200 is a female terminal, and the rubber core 1 is correspondingly a female rubber core. The plug-in end 12 of the rubber core 1 is provided with a plug-in cavity 121 that is connected to the receiving cavity. The conductive terminal 2 is located in the plug-in cavity 121, and the conductive terminal 2 is in close contact with the inner circumferential wall of the plug-in cavity 121. The plug-in cavity 121 can increase the mechanical connection strength.

[0045] In summary, the board-mounted parallel connector 300 of the present invention provides a connection terminal 3 electrically connected to the conductive terminal 2 at the mounting end 11 of the rubber core 1, and provides multiple connection slots 31 for inserting conductive wires on the side of the connection terminal 3 away from the conductive terminal 2. This allows for the electrical connection of multiple conductive wires to the conductive terminal 2, and for these multiple conductive wires to be connected in parallel. Compared to the prior art, the board-mounted parallel connector 300 of the present invention can achieve parallel connection of multiple conductive wires outside the device, and the connector is convenient to connect, occupies a relatively small space, and has a low overall cost.
