It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1 to 5, a connection terminal 100 according to an embodiment of the present invention includes a main body 110, a conductive member 130 fixed on the main body 110, and a self-locking assembly.
Specifically, the main body is non-conductive, and both opposite ends of the main body 110 are provided with wire inlets 111. The main body 110 is provided with two wire connection spaces 113 respectively communicating with the two wire inlets 111. So that the lead wire can be extended into the wiring space 113 through the wire inlet 111.
The conductive member 130 includes two conductive portions 131 respectively extending into the two wiring spaces 113. The self-locking assembly includes an abutting member 151 abutting against the conduction portion 131. The contact member 151 has a contact surface 152 contacting the conductive portion 131, and the contact surface 152 can move or rotate under an external force so that a gap through which the conductive wire passes is formed between the contact surface 152 and the conductive portion 131.
In other words, the contact member 151 is in contact with the conductive part 131 without an external force. Under the action of the external force, a gap is formed between the contact surface 152 of the contact member 151 and the conduction portion 131. Therefore, a gap is formed between the contact surface 152 of the contact member 151 and the conduction part 131 by an external force, so that the lead can be conveniently inserted between the contact member 151 and the conduction part 131 or be pulled out from between the contact member 151 and the conduction part 131. The external force is removed, so that the wire is clamped between the abutting member 151 and the conduction part 131, and the wire is prevented from slipping.
It can be understood that the wire is clamped between the abutting piece 151 and the conduction part 131 to achieve the electrical connection of the wire and the conduction part 131.
In the wiring terminal, the conducting wire is clamped between the conducting part 131 and the abutting part 151 by the abutting of the abutting part 151 and the conducting part 131, the abutting of the abutting part 151 and the conducting part 131 is not influenced by human factors, namely, the phenomenon that the conducting wire cannot be clamped due to the human factors can be avoided, and the conducting wire can be effectively ensured to be clamped. In addition, the contact between the contact member 151 and the conduction part 131 is not affected by human factors, so that the phenomenon that the wiring terminal is damaged due to over-tightening of the screw is avoided.
In addition, under the action of no external force, the abutting piece 151 abuts against the conducting part 131, even under the action of vibration or external force, the abutting piece 151 always abuts against the conducting part 131, the phenomenon that the traditional screw is loosened under the action of vibration or external force is avoided, and therefore the phenomenon of poor contact of the conducting wire is avoided.
Furthermore, under the effect of no external force, the abutting piece 151 abuts against the conduction part 131, so that the phenomenon of poor contact of the lead can be effectively avoided, the maintenance times and time of operators can be reduced, the work of the operators is reduced, and manpower and material resources are saved.
In the present embodiment, the wire inlet 111 and the gap between the contact member 151 and the conduction part 131 are disposed to face each other, so that when the wire is inserted into the connection space 113 through the wire inlet 111, the wire is smoothly inserted between the contact member 151 and the conduction part 131.
In this embodiment, the conductive member 130 is exposed at one side of the main body 110. It should be noted that, in general, when in use, a plurality of connection terminals 100 are arranged side by side, so that the conductive member 130 is covered by the main body 110 of the adjacent connection terminal 100, thereby avoiding the exposure of the conductive member 130.
On one hand, the installation process of the conductive member 130 can be simplified. On the other hand, the size of the main body 110 can be reduced, so that the size of the wiring terminal 100 is reduced, the occupied space of the wiring terminal 100 is reduced, the wiring terminal 100 is suitable for a use space with a narrow space, and the application range of the wiring terminal 100 is widened.
In addition, in general, the connection terminal 100 is applied to a control portion of a wiring, i.e., a secondary connection portion. Of course, in another circuit, the terminal 100 is also suitable for the circuit if the conductor to which the terminal 100 can be connected meets the requirements of the circuit.
In this embodiment, the abutting member 151 is a spring piece disposed in the wiring space 113. The contact member 151 has one end contacting a sidewall of the wiring space 113 and the other end contacting the conductive portion 131. It can be understood that the abutment 151 is in a compressed state between the sidewall of the wiring space 113 and the conduction part 131, so that the abutment 151 can maintain the abutment state with the conduction part 131 by its own elastic force.
In this embodiment, the abutting member 151 is V-shaped, and the opening direction of the abutting member 151 deviates from the wire inlet 111, so that the wire can be smoothly inserted between the abutting member 151 and the conduction part 131 along the outer surface of the abutting member 151, rather than being inserted into the recessed area or other positions of the abutting member 151.
Of course, it will be appreciated that in other possible embodiments, the abutment member is not limited to being V-shaped, but may also be other regular or irregular shapes. The wire connecting device can be arranged between the side wall of the wire connecting space and the conduction part and is in a compressed state, and the wire is clamped between the abutting piece and the conduction part.
In this embodiment, the non-slip projection 132 is provided on the side of the conduction part 131 close to the contact member 151. Thus, the wire extending between the abutting member 151 and the conduction part 131 is non-linear due to the anti-slip protrusions, and the wire is effectively prevented from slipping off between the abutting member 151 and the conduction part 131.
Referring to fig. 2 and 4, in the embodiment, the anti-slip protrusion 132 is inclined in a direction away from the wire inlet 111 to prevent the wire from being bent excessively, so as to prevent the wire from being broken due to the excessive bending.
Further, in the present embodiment, the anti-slip projection 132 abuts against the abutment 151, so that the wire is further prevented from slipping off by the clamping of the anti-slip projection 132 and the abutment 151.
Referring to fig. 2, 3 and 5, in the present embodiment, the self-locking assembly includes an operating member 153 disposed on the main body 110 and capable of controlling the abutting surface 152 to move. The movement of the abutment surface 152 can thus be easily achieved by operating the operation member 153.
Specifically, in the present embodiment, the operating element 153 is provided with the pressing portion 154 abutting against the abutting piece 151, so that by pressing the operating element 153, the abutting portion 151 is elastically deformed, and further the abutting surface 152 of the abutting portion 151 is moved, so that a gap is provided between the abutting portion 151 and the conduction portion 131.
It can be understood that, in the present embodiment, the pressing portion 154 and the conducting portion 131 are both located on the same side of the abutting member 151, and the pressing portion 154 and the conducting portion 131 are arranged side by side, so that the pressing portion 154 and the conducting portion 131 can be abutted against the abutting portion 151 at the same time.
Further, in the present embodiment, the main body 110 is provided with a receiving hole 115, and the operating element 153 is completely trapped in the receiving hole 115, so as to prevent the connecting terminal 100 from being pressed by an external object and mistakenly touching the operating element 153.
It will be appreciated that, in other possible embodiments,
in this embodiment, the main body 110 is provided with a testing hole 117 extending to the conductive member 130. Thereby allowing the testing end of a testing tool, such as a multimeter, to be electrically connected to the conductive member 130 by extending into the testing aperture 117.
Alternatively, in the present embodiment, the surface of the body 110 provided with the test hole 117 is adjacent to the surface of the body 110 provided with the conductive member 130, so as to prevent the body 110 of the adjacent connection terminal 100 from covering the test hole 117. Therefore, even if a plurality of the connection terminals 100 are used side by side, each of the connection terminals 100 can be tested at any time.
In this embodiment, the main body 110 is provided with a short port 119 extending to the conductive member 130. The shorting line may extend into shorting port 119 and electrically connect to conductive member 130. The two ends of the short connection wire extend into the short connection ports 119 of the different wiring terminals 100 respectively, so that short circuits of the different wiring terminals 100 can be realized as required, and then short circuits of wires connected into the different wiring terminals 100 are realized.
It is understood that, in another possible embodiment, the abutting member is not limited to the elastic member, and may abut against the conducting portion, so that the lead is clamped and fixed between the abutting member and the conducting portion.
Accordingly, in another feasible embodiment, the space for the lead to pass through is not limited to be formed between the abutting surface and the conducting part only by moving the abutting surface, the space for the lead to pass through can be formed between the abutting surface and the conducting part by rotating the abutting surface, and the space for the lead to pass through can be formed between the abutting surface and the conducting part by simultaneously moving and rotating the abutting surface.
Optionally, in a further possible embodiment, the self-locking assembly further comprises a resilient member. One end of the elastic piece is abutted against the abutting piece, and the other end of the elastic piece is abutted against the side wall of the wiring space, so that the abutting piece is abutted against the conduction. That is, the abutting member may abut against the conduction portion by the elastic force of the elastic member, or the abutting member may abut against the conduction portion by the common action of the elastic force of the elastic member and the elastic force of the abutting member.
It will be appreciated that the resilient member is also in a compressed state to give the abutment member a resilient force against which the conducting portion abuts.
It is understood that, in another possible embodiment, one end of the elastic member may be fixedly connected to the main body, the other end of the elastic member may be fixedly connected to the abutting member, and the elastic member is in a stretched state, so as to provide an elastic force for the abutting member to abut against the conduction portion.
It is to be understood that, in another possible embodiment, the manner of abutting the abutment member with the conduction part is not limited to this, and for example, the abutment member may be abutted with the conduction part or the gap may be provided between the abutment member and the conduction part by rotating the cam, or the abutment member may be provided in a cam structure to abut the abutment member with the conduction part or the gap may be provided between the abutment member and the conduction part by rotating the abutment member.
In the terminal 100, the contact surface 152 is in line contact with the conductive portion 131.
It is understood that, in another possible embodiment, the abutting surface and the conduction part are not limited to surface contact, but may be point contact or surface release.
