Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

In one embodiment, referring to fig. 1, fig. 2 and fig. 3, a wiring structure 100 includes: a connecting wire 110, an adapter 120 and a socket 130. One of the connecting wire 110 and the adaptor 120 is provided with a plugging portion 111, and the other is plugged into the plugging portion 111, so that the connecting wire 110 and the adaptor 120 are electrically connected. The socket 130 is provided on the valve body 200, and the socket 130 is provided with a connection hole 131. The adaptor 120 is inserted into the connection hole 131 at one end and is used to electrically connect with a wire on the valve body 200.

In the wiring structure 100, the insertion portion 111 is disposed between the connecting line 110 and the adaptor 120, so that the wiring manner between the connecting line 110 and the adaptor 120 is changed into a quick insertion type. Therefore, in the connection between the connection line 110 and the adaptor 120, the connection line 110 or the adaptor 120 can be electrically connected only by inserting the connection line 110 or the adaptor 120 into the insertion part 111. Since the socket 130 is provided with the connection hole 131, in the connection between the adaptor 120 and the valve body 200, one end of the adaptor 120 is inserted into the connection hole 131, and the adaptor 120 is connected to the lead wire of the valve body 200 to electrically connect the two. The wiring structure 100 utilizes the adaptor 120 to replace the connecting wire 110 to be directly welded with the valve body 200, manual support is not needed, and the operation amount in the wiring process is reduced. Meanwhile, the connection wires at the two ends of the adapter 120 are all in a plug-in mode, so that the connection operation is more convenient, the assembly is simple, the automatic production is easy to realize, and the production efficiency and the qualified rate are improved.

The insertion portion 111 may be provided on the connection line 110 or on the adaptor 120. When the plugging part 111 is arranged on the connecting line 110, one end of the adaptor 120 is plugged into the plugging part 111 on the connecting line 110; when the insertion part 111 is disposed on the adaptor 120, one end of the connecting wire 110 is inserted into the insertion part 111 on the adaptor 120.

It should be noted that, when one end of the adaptor 120 is inserted into the connection hole 131, there are various connection modes between the adaptor 120 and the wires of the valve body 200, and it is only necessary that both are capable of conducting electricity stably. Such as: the adaptor 120 and the lead of the valve body 200 may be connected by binding, or winding. In addition, the material of the adaptor 120 is not particularly limited, and only the connection line 110 and the lead of the valve body 200 need to be electrically connected, for example: the adaptor 120 is a copper needle, an iron needle, or the like.

Additionally, the wires on the valve body 200 should be understood to be the wires that run out of the coil terminals within the solenoid valve. For convenience of understanding, the two-coil switch type solenoid valve is taken as an example, the conducting wires on the valve body 200 may be the first end and the second end of the valve opening coil 220, or the guiding wires correspondingly led out from the first end and the second end of the maintaining coil 230, and of course, the conducting wires may be led out as a common connecting end or individually led out, and are not limited herein, and may be designed according to actual power requirements.

Further, referring to fig. 2, the plugging portion 111 is disposed on the connection line 110, and the plugging portion 111 is provided with a jack 112. One end of the adaptor 120 is inserted into the insertion hole 112 and electrically contacts with the connection line 110, so as to quickly complete the electrical connection between the adaptor 120 and the connection line 110, thereby improving the assembly efficiency of the solenoid valve. The insertion part 111 should be made of a non-conductive material to prevent the electric leakage phenomenon on the insertion part 111.

Further, referring to fig. 2, the adaptor 120 includes a first adaptor section 121 and a second adaptor section 122 connected to the first adaptor section 121. The first transition segment 121 intersects the second transition segment 122. The first transition piece 121 is inserted into the insertion hole 112. The second adaptor section 122 is inserted into the connection hole 131. Therefore, the adaptor 120 is designed to be in a bent state, so that the plugging directions of the two opposite ends of the adaptor 120 are also crossed, thereby ensuring that the connecting wire 110 connected to the adaptor 120 can be pressed on the valve body 200, facilitating the wiring on the valve body 200 and reducing the occupied space.

It should be noted that, the first transition section 121 and the second transition section 122 formed on the transition piece 120 in an intersecting manner may be completed before the wiring, for example: before wiring, the adaptor 120 is bent into a first adaptor section 121 and a second adaptor section 122; or the first switching section 121 and the second switching section 122 are placed at a certain angle and are spliced by welding, pin joint, bolt connection and the like. Of course, the first transition section 121 and the second transition section 122 on the transition piece 120 can also be completed in the middle of wiring. Such as: after both ends of the adaptor 120 are inserted into the insertion part 111 and the connection hole 131, respectively, the connection line 110 is pressed toward the valve body 200, so that the adaptor 120 is bent to form the first adaptor section 121 and the second adaptor section 122 disposed to intersect.

In one embodiment, the adapter piece 120 is configured to be wrapped around a wire on the valve body 200 to electrically connect the adapter piece 120 to the wire on the valve body 200. Therefore, referring to fig. 2, when one end of the adaptor 120 is inserted into the connecting hole 131, the wire on the valve body 200 is wound around the adaptor 120, so that the wire and the adaptor 120 are not only mechanically connected, but also stably electrically connected. The winding mode can be automatically completed through a winding machine, and can also be completed through manual winding.

In one embodiment, the wiring structure 100 further includes a tin layer. The tin layer is used for wrapping the wires on the adaptor 120 and the valve body 200, so that the wires on the adaptor 120 and the valve body 200 are tightly combined, the connection strength of the adaptor and the valve body is improved, and the stability of power supply of the electromagnetic valve is ensured. Meanwhile, the tin layer is wrapped on the adapter piece 120 and the lead, so that a protection effect is provided for the adapter piece and the lead, and the adapter piece and the lead are prevented from being directly exposed to the outside and being easily oxidized.

It should be noted that the tin layer may be wrapped on the interposer 120 and the wires by immersion tin. After the adaptor 120 is connected with the lead of the valve body 200, automatic tin immersion is carried out, and a manual welding process is omitted, so that the overall assembly efficiency of the electromagnetic valve is improved.

In one embodiment, referring to fig. 2, the socket 130 is provided with a protrusion 132. The protruding portion 132 and the connecting wire 110 are respectively located at two opposite sides of the connecting hole 131, and the protruding portion 132 is used for shielding one side of the connecting hole 131. Therefore, the protruding portion 132 is equivalent to a shielding structure with respect to the connecting hole 131, and provides protection for one side of the connecting hole 131, so as to prevent dirt from entering the connecting hole 131 and causing short circuit between the adaptor 120 and the wire, thereby effectively ensuring the electrical safety of the solenoid valve.

It should be noted that, when the shielding effect is achieved, there is a height difference between the protrusion 132 and the socket 130, such as: the top surface of the protrusion 132 is higher than the side of the socket 130 having the connection hole 131, so as to better provide a shielding effect for the connection hole 131.

Further, referring to fig. 2, a guide slot 1321 is disposed on a side surface of the protruding portion 132 facing the connection hole 131. The guide slot 1321 communicates with the connection hole 131. Therefore, in the plugging process, the adaptor 120 can move along the guiding slot 1321, and can be accurately and quickly inserted into the connecting hole 131, so that the wiring of the solenoid valve is more convenient.

In one embodiment, there are more than two connecting holes 131, protrusions 132, adapters 120, and connecting wires 110. Two or more connection holes 131 are provided at intervals on the socket 130. The protrusions 132 are disposed in one-to-one correspondence with the connection holes 131.

Specifically, referring to fig. 2 and fig. 5, there are three connecting holes 131, three protruding portions 132, three adapters 120 and three connecting wires 110. The solenoid valve is a dual-coil switch-type solenoid valve, one adapter 120 is electrically connected to a first end of the valve opening coil 220, one adapter 120 is electrically connected to a second end of the valve opening coil 220 and a first end of the maintaining coil 230, respectively, and one adapter 120 is electrically connected to a second end of the maintaining coil 230.

In one embodiment, referring to fig. 1, the wiring structure 100 further includes a plug 140. One end of the connecting wire 110 away from the adaptor 120 is connected to the plug 140, so that the connecting wire 110 is electrically connected to an external power source.

In one embodiment, referring to fig. 4 and 5, a solenoid valve includes a valve body 200 and the wiring structure 100 of any of the above embodiments. The socket 130 is provided on the valve body 200.

The electromagnetic valve adopts the wiring structure 100, and the insertion part 111 is arranged between the connecting wire 110 and the adaptor 120, so that the wiring mode between the connecting wire 110 and the adaptor 120 is changed into a quick insertion mode. Therefore, in the connection between the connection line 110 and the adaptor 120, the connection line 110 or the adaptor 120 can be electrically connected only by inserting the connection line 110 or the adaptor 120 into the insertion part 111. Since the socket 130 is provided with the connection hole 131, in the connection between the adaptor 120 and the valve body 200, one end of the adaptor 120 is inserted into the connection hole 131, and the adaptor 120 is connected to the lead wire of the valve body 200 to electrically connect the two. The wiring structure 100 utilizes the adaptor 120 to replace the connecting wire 110 to be directly welded with the valve body 200, manual support is not needed, and the operation amount in the wiring process is reduced. Meanwhile, the connection wires at the two ends of the adapter 120 are all in a plug-in mode, so that the connection operation is more convenient, the assembly is simple, the automatic production is easy to realize, and the production efficiency and the qualified rate are improved.

It should be noted that the wiring structure 100 of the present embodiment can be applied to different types of solenoid valves, such as: the wiring structure 100 is applicable to a single-coil switch-type solenoid valve, a double-coil switch-type solenoid valve, and the like.
