[0026] In order to make the purpose, 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.

[0027] See also Figure 1-8 As shown, the present invention discloses an application system of a board-mounted parallel connector, including a board-mounted parallel connector 300, which is electrically connected to a device (not shown) to input current or signal to the device, or output current or signal inside the device to the outside. The board-mounted parallel connector 300 is installed on the housing of the device, and one end extends into the inside of the device. A plurality of conductive wires (not shown) are connected inside the device, and the plurality of conductive wires need to be connected in parallel with each other and then electrically connected to the electronic components inside the device. The board-mounted parallel connector 300 is electrically connected to the plurality of conductive wires to realize the mutual parallel connection of the plurality of conductive wires. The board-mounted parallel connector 300 can realize the mutual parallel connection of the plurality of conductive wires outside the device. That is, the board-mounted parallel connector 300 can replace the situation where a plurality of groups of conventional connectors that can only be connected to one conductive wire are installed on the housing, and the plurality of conductive wires used to connect to a plurality of conventional connectors do not need to be connected in parallel inside the device. The board-mounted parallel connector 300 of the present invention can reduce the space occupied by the connector on the device, and the connector wiring is convenient and the overall cost is low.

[0028] The on-board parallel connector 300 includes a male parallel connector 100 and a female parallel connector 200, and at most one set of the male parallel connector 100 and the female parallel connector 200 is installed on the housing of the device. It is used to input current or signals to the device, or output the current or signals inside the device to the outside.

The on-board parallel connector 300 can save the internal space of the device, reduce the volume of the device, and save costs.

[0029] The 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.

[0030] 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 one 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 with each other. 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 the multiple conductive wires inserted in the corresponding wiring slots 31 can be connected in parallel, and there is no limitation on this.

[0031] Combination Figure 4 and Figure 5 As shown, the wiring terminal 3 includes an integrally formed wiring terminal 32 and a connecting terminal 33, the wiring slot 31 is located at the wiring terminal 32, and the connecting terminal 33 extends toward the conductive terminal 2 to be connected to the conductive terminal 2. In this embodiment, the wiring terminal 32 and the connecting terminal 33 are both cylindrical, and the radius of the wiring terminal 32 is greater than the radius of the connecting terminal 33. Of course, in other optional embodiments, the wiring terminal 32 and the connecting terminal 33 can also be arranged in other shapes, which are not limited by comparison.

[0032] 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.

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.

[0033] The connection terminal 3 is provided with a connection slot 35 for inserting the conductive terminal 2 on one side thereof facing the conductive terminal 2, so as to be plugged and fixed with the conductive terminal 2. Specifically, the connection slot 35 is provided at the connection end 33. In other optional embodiments, the conductive terminal 2 and the connection terminal 3 may be integrally formed, which is not limited thereto.

[0034] Combination 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 from the receiving cavity 111. Specifically, the limiting hole 34 is exposed from the receiving cavity 111, so as 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 and matches with the step portion 112 to limit the wiring terminal 3. The plug end 12 is used for snap connection with a corresponding connector, and the plug end 12 is provided with a plug cavity 121 communicating with the receiving cavity 111, the conductive terminal 2 is located in the plug cavity 121, and the conductive terminal 2 is spaced apart from the inner peripheral wall of the plug cavity 121. The plug cavity 121 can increase the mechanical connection strength.

[0035] The male end parallel connector 100 also includes a housing 5 assembled on the outside of the wiring terminal 3, and the housing 5 is snap-connected with the mounting end 11. Preferably, the mounting end 11 is provided with a protruding fastener 113, and the housing 5 is correspondingly provided with a fastening groove 51, and the fastener 113 extends into the fastening groove 51 to achieve the installation of the housing 5 and the rubber core 1.

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 covered on the outside of the plug 7 and is threadedly connected to the housing 5. In this embodiment, the housing 5 is connected to the shell of the device, and the plug 7 and the wire lock nut 8 are located inside the device. The plug 7 is spaced apart from the wiring terminal 3, and can arrange the conductive wires. The wire lock nut 8 is used to limit the plug 7 in the housing 5.

[0037] like Figure 1 and Figure 8 As shown, when the onboard parallel connector 300 in the 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 corresponds to a female rubber core. The plug-in end 12 of the rubber core 1 is provided with a plug-in cavity 121 connected to the receiving cavity, and 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.
