Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an arc-proof and fool-proof connector. Background Art

[0002] A connector is an electronic component used for transmission and exchange of current or optical signals between electronic system devices. As a node, it transmits current or optical signals between devices, components, equipment, and subsystems independently or together with cables, and keeps the signal distortion and energy loss between systems unchanged. It usually consists of two connectors, which are plugged into the internal terminals to achieve current transmission or signal exchange.

[0003] However, current connectors are basically equipped with multiple terminals that are fixed and conductive after insertion. However, due to the disordered distribution of the terminals, when users plug two connectors together, there is no identification mark to identify the direction of plugging together, which can easily damage the internal structure due to blind plugging. In addition, when the terminals are inserted, arcing is easily caused, affecting the use of the connector. Utility Model Content

[0009] Furthermore, the first connecting member is provided with a first power connection head extending outwards to connect to electricity, and the second connecting member is provided with a second power connection head extending outwards to connect to electricity.

[0010] Furthermore, a locking ring which is locked on the outside after being rotated axially is provided between the first connecting member and the second connecting member.

[0011] Furthermore, a waterproof ring is provided at the connection between the first connection part and the second connection part.

[0012] Furthermore, the male connection monomers are distributed in a ring shape with the central axis of the male connection end as a base point.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model provides an arc-proof and fool-proof connector, which is mainly composed of a first connector 1 and a second connector 2, and the first connector 1 and the second connector 2 are connected by plugging. The specific structure for convenient plugging is that the first connector 1 is provided with a first connecting portion 3, and the second connector 2 is provided with a second connecting portion 4 that plugs into the first connecting portion 3. Since the plugging structure includes two parts, a concave part and a convex part, in order to cooperate with the description of other technical features of the first connector 1 and the second connector 2, the structure of the first connecting portion 3 and the second connecting portion 4 needs to be described in two embodiments.

[0031] Embodiment 1:

[0032] like Figure 1-6 As shown, when the first connection portion 3 on the first connection member 1 is a convex structure, the second connection portion 4 on the second connection member 2 is a corresponding concave structure.

[0033] A male connection end 5 coaxially arranged with the first connection part 3 is also provided inside the first connection member 1. At this time, the male connection end 5 is connected to the top surface of the first connection part 3 and is connected as one piece. The male connection end 5 is composed of three male connection monomers 6 distributed at intervals, and the three male connection monomers 6 are distributed in a ring with the central axis of the male connection end 5 as the base point. Correspondingly, a female connection end 7 coaxially arranged with the second connection part 4 is also provided inside the second connection member 2, and the female connection end 7 is arranged at the bottom of the second connection part 4. The female connection end 7 is composed of three female connection monomers 8 distributed at intervals, and the three female connection monomers 8 are plugged into the three male connection monomers 6 one by one.

[0034] After the male connection monomer 6 and the female connection monomer 8 are plugged in and connected, in order to make the internal conductive, terminals for conductivity are installed in the first connector 1 and the second connector 2. That is to say, after the first connector 1 and the second connector 2 are plugged in and connected and fixed, the internal terminals are also synchronously contacted and conductive. At this time, a slot 10 is provided in the male connection monomer 6, and at the same time, a terminal plug 11 with a protrusion inserted into the slot 10 is provided in the female connection monomer 8. The terminal plug 11 and the terminal inside the second connector 2 are integrally formed. Structurally, the depth of the slot 10 is the plug-in distance between the first connector 1 and the second connector 2. That is to say, the premise that the terminal plug 11 is connected and conductive in the slot 10 is that the first connector 1 and the second connector 2 are completely closed. In order to avoid the occurrence of arcing when the terminal plug 11 is inserted into the slot 10, among the three terminal plugs 11, the length of one of the terminal plugs 11 is longer than the other two. The terminal plug 11 with a long enough length can be brought in in advance as a ground wire, which can not only avoid arcing, but also improve the safety of use.

[0035] In order to prevent blind insertion when connecting the first connector 1 and the second connector 2, and to prevent damage to the same-fold structure of the first connector 1 and the second connector 2, an anti-mistake point 9 for convenient identification of direction is provided at the connection between the male connecting unit 6 and the female connecting unit 8, which can better protect the internal structure of the first connector 1 and the second connector 2.

[0036] In addition, in order to improve the sealing of the connection between the first connecting member 1 and the second connecting member 2, a waterproof ring 15 is provided at the connection after the first connecting part 3 and the second connecting part 4 are inserted into each other, which can enhance the waterproof effect of the connection between the two. The waterproof ring 15 is sleeved on the outside of the first connecting part 3.

[0037] As for the external structure after the first connector 1 and the second connector 2 are connected, a locking ring 14 for common locking is provided at the connection between the two. The locking ring 14 is inserted from the outside of the first connector 1 and locked with the outside of the second connector 2 by rotating. A threaded body is provided at the locking position. At the same time, in order to facilitate the first connector 1 and the second connector 2 to be connected to an external mechanism, a first power connection head 12 extending outward for power connection is provided at one end of the first connector 1 away from the second connector 2. Similarly, a second power connection head 13 extending outward for power connection is provided at one end of the second connector 2 away from the first connector 1.

[0038] Embodiment 2:

[0039] like Figure 7-12 As shown, when the first connection portion 3 on the first connection member 1 is a recessed structure, the second connection portion 4 on the second connection member 2 is a corresponding raised structure.

[0040] The difference between the present embodiment 2 and the embodiment 1 is that the first connection part 3 on the first connection member 1 is a concave structure, the male connection end 5 coaxially arranged with the first connection part 3 is arranged at the bottom of the first connection part 3 after the concave, and correspondingly, the female connection end 7 coaxially arranged with the second connection part 4 is arranged at the concave position of the top of the protrusion, and in addition, the locking ring 14 is inserted from the outside of the second connection member 2 and locked with the outside of the first connection member 1 after being rotated. Compared with the technical solution of the embodiment 1, the present embodiment 2 has the same technical effect.

[0041] Compared with the traditional technology, when the first connector 1 and the second connector 2 are plugged in, an anti-mock point 9 is set at the connection between the male connecting terminal 5 and the female connecting terminal 7 to facilitate the direction positioning during plugging in and avoid damage to the internal structure caused by blind plugging. At the same time, one of the terminal plugs 11 connected during plugging is longer and can be inserted in advance to be used as a conductive ground wire to avoid arcing during connection.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
