[0007] Preferably, the pressing member further comprises a connecting arm connected to the pressing arm, and a pressing groove is provided on a side of the connecting arm away from the pressing arm.

[0008] Preferably, the spring sheet includes a supporting portion abutting against the inner wall of the wiring channel and a first bending portion arranged at the end of the supporting portion, the first bending portion and the supporting portion are arranged at an angle, and the pressing member can pass through the first through hole and abut against the first bending portion.

[0009] Preferably, the portion where the pressing member abuts against the first bending portion is inclined.

[0010] Preferably, the support portion is further provided with a second bending portion at the other end relative to the first bending portion, a limiting portion is provided on the second bending portion, a trigger is provided near the wiring channel, the upper shell is provided with an operating groove corresponding to the trigger, the trigger includes a controlling claw located between the upper shell and the main shell, and a pulling portion exposed to the outside through the operating groove, and the controlling claw abuts against the upper shell and the limiting portion at the same time.

[0011] Preferably, the wiring channel includes a wiring port close to the trigger, the upper shell covers the wiring port and has an opening corresponding to the wiring port, the upper shell has an operating slot corresponding to the trigger, and the trigger passes through the operating slot to abut the limiting portion.

[0013] Preferably, a limiting convex strip is provided on the inner wall of the wiring channel, and the supporting portion is at least partially clamped between the limiting convex strip and the inner wall of the wiring channel.

[0014] Compared with the prior art, the connector provided by the utility model has the following advantages:

[0015] 1. The connector provided in the embodiment of the utility model comprises a main shell and an upper shell clamped on the main shell. The upper shell and the main shell are the outer shell parts of the connector, which provide protection and support around the internal components. A spring sheet is arranged in the main shell. When the wiring operation is performed, the pressing piece on the upper shell is pressed to drive the pressing arm to abut against the spring sheet, so that it is deformed by force, and the spring sheet will be offset away from the original position by a certain distance. At this time, one of the wires to be connected is placed in the main shell. When the pressing stops, the spring sheet will rebound to its original position, thereby squeezing the wire placed in the original position of the spring sheet to connect and clamp the wire. The second perforation helps the electrician to operate the pressing piece, provides a pressing space, and provides a limit fixation for fixing the pressing piece in the upper shell. The first perforation provides a contact space for the pressing piece to press against the spring sheet. The wiring method is simple to operate and can be set on a small connector, which is convenient to operate, and has a simple structure and low cost.

[0016] 2. In the connector provided in the embodiment of the utility model, the pressing piece is arranged in the second through hole of the upper shell, and the end surface of the pressing piece away from the spring sheet can be parallel to the end surface of the upper shell away from the main shell or concave than the end surface of the upper shell away from the main shell. The height limitation can reduce the possibility of collision between the pressing piece and other objects, prevent collision and damage, and avoid non-professionals from misoperating the pressing piece. Based on the certain danger of electrical connector technology, the pressing piece can only be pressed by professionally trained electricians using tools, and the height limitation ensures safety.

[0017] 3. In the connector provided in the embodiment of the utility model, the slide groove on the second through hole provides a sliding space for the protrusion on the pressing arm. The cooperation between the protrusion and the slide groove ensures that the pressing piece slides smoothly in the second through hole and realizes precise position control, thereby increasing the fixation of the pressing piece and reducing the risk of loosening and separation.

[0018] 4. In the connector provided in the embodiment of the utility model, the pressing groove is used to allow an external screwdriver to act on the pressing piece, which is convenient for maintenance and adjustment. The connecting arm limits the pressing arm and locks the wiring part in the connector. In actual operation, it is easier to tighten or apply force using a screwdriver or a wrench.

[0019] 5. In the wiring connector provided in the embodiment of the utility model, the spring sheet includes a support portion abutting the connecting channel and a first bent portion arranged at one end of the support portion, the first bent portion and the support portion are arranged at an angle, and the elastic property of the spring sheet enables the first bent portion and the support portion arranged at an angle to still maintain good supporting performance, and can help the support portion better fit the inner wall of the connecting wiring channel to ensure the stability of the connection; when the pressing operation is performed, the pressing arm passes through the first perforation and abuts against the first bent portion, the first bent portion is deformed, and a gap is formed between the first bent portion and the original position, providing a space for the wire to be connected, and in order to make the force on the pressing piece more directly and effectively transmitted to the first bent portion, the side of the pressing arm abutting against the first bent portion is adaptively set to be inclined like the inclined first bent portion, so that the force transmission is more accurate and direct.

[0020] 6. In the wiring connector provided in the embodiment of the utility model, the other end of the support portion relative to the first bending portion is further provided with a second bending portion, the first bending portion and the support portion are arranged at an angle, similarly, the second bending portion and the support portion are also arranged at an angle, and a limiting portion is arranged on the second bending portion. A trigger is arranged near the wiring channel, and when the trigger is pulled, the trigger abuts against the limiting portion of the second bending portion, so that the second bending portion is deformed by force, and when the trigger stops being pulled, the second bending portion of the spring sheet will rebound to its original position, thereby achieving the connection and clamping of the wire.

[0021] 7. The trigger of the connector provided in the embodiment of the utility model includes a control claw and a pull portion. The control claw controls and fixes the position of the trigger between the upper shell and the main shell to ensure that the position of the trigger in the operating slot is stable. The pull portion is a part of the trigger, which passes through the operating slot and is exposed to the outside. The electrician can manipulate the trigger through the pull portion to achieve the plugging, unplugging or locking of the connector. The limit portion abuts against the control claw to limit the movement range of the trigger to ensure that the trigger is in a proper position, making the process of connecting or removing the wire easier to operate. After the wire is connected, it is more stable and not easy to fall off from the channel under the influence of external force. In addition, the trigger is stored in the operating slot, which can make the size of the connector smaller and improve the durability, stability and ease of use of the connector.

[0022] 8. In the wiring connector provided in the embodiment of the utility model, the wiring port is the entrance of the connector, through which the wire or connector can be inserted, the upper shell covers the wiring port, and the opening corresponding to the wiring port allows the wire to pass through. The upper shell protects the wiring port and makes it more convenient to insert the wire. A trigger is set on one side of the second bending part, and the electrician can use the trigger to control another wire of the connector. The trigger is lifted or lowered in the operation slot, and the trigger passes through the operation slot and abuts the limit part to ensure the stability of the trigger and prevent it from swinging excessively or falling off. The trigger makes it easier to operate the process of inserting or removing the wire at one end of the second bending part. After the wire is inserted, it is more stable and not easy to fall out of the channel under the influence of external force. When the trigger is pulled, the trigger abuts the limit part of the second bending part, so that the second bending part is deformed by force. When the trigger stops pulling, the second bending part of the spring will rebound to its original position, thereby realizing the insertion and clamping of the wire. The coordinated design of the trigger and the operating slot makes the process of inserting or removing the wire easier to operate. After the wire is inserted, it is more stable and not easy to fall out of the channel under the influence of external force.

[0023] 9. In the connector provided in the embodiment of the utility model, a conductive member is further provided in the main housing, and the two ends of the conductive member are respectively in contact with the first bend and the second bend. The first bend and the second bend are in contact with, approached or moved away from the conductive member by pressing the pressing arm or pulling the trigger. When no force is applied, the first bend and the second bend are in contact with the conductive member to tightly clamp the wire, thereby realizing the electrical connection between the incoming wire and the outgoing wire.

[0024] 10. The connector provided in the embodiment of the utility model has a limiting convex strip on the inner wall of the wiring channel, which limits the supporting part of the spring piece and makes the connection between the supporting part and the inner wall of the wiring channel more stable, preventing the spring piece from shaking in the main shell when subjected to force, thereby affecting the speed and quality of wiring.

[0040] Please combine Figure 1 and Figure 2 The first embodiment of the utility model provides a connector 1, including a main shell 11 and an upper shell 12 connected to the main shell 11, the main shell 11 is provided with at least one through wiring channel 111, a spring piece 112 is arranged in the wiring channel 111, a first through hole 113 communicating with the wiring channel 111 is arranged on a side of the main shell 11 facing the main shell 11, a second through hole 121 is arranged in the upper shell 12 corresponding to the first through hole 113, a pressing piece 13 is movably arranged in the second through hole 121, the pressing piece 13 passes through the first through hole 113 and abuts against the spring piece 112, and the wiring channel 111 is opened or closed by pressing the pressing piece 13 against the spring piece 112.

[0041] It can be understood that when wiring, the wire is connected to the connector 1 through the pressing cooperation between the spring piece 112 in the wiring channel 111 and the pressing piece 13 abutting against the spring piece 112 to complete the wiring. The pressing piece 13 set in the upper shell 12 is pressed by an external screwdriver or other objects that can be inserted into the second through-hole 121. The pressing piece 13 as a whole can slide in the second through-hole 121. The screwdriver applies a force to the pressing piece 13 toward one side of the main shell 11, and drives the pressing arm 131 to abut against the spring piece 112, so that it is deformed by the force. The spring piece 112 is subjected to the force that forces it to deviate from its original position. When the pressing stops, the spring piece 112 will rebound to its original position, thereby realizing the connection and clamping of the wire.

[0042] Furthermore, a main housing 11 of a connector 1 provided by the present invention can be provided with a plurality of wiring channels 111 so as to realize the task of wiring multiple wires simultaneously. The plurality of wiring channels 111 matched with a plurality of pressing members 13 can meet the requirements of convenient and fast wiring.

[0043] Specifically, the pressing member 13 is entirely arranged in the second through-hole 121 in the upper shell 12, and the pressing arm 131 on the pressing member 13 passes through the first through-hole 113 arranged in the main shell 11. In the present embodiment, the shapes of the first through-hole 113 and the second through-hole 121 are not specifically limited, as long as the pressing member 13 can slide in the second through-hole 121 and the pressing arm 131 can pass through the first through-hole 113 and abut against the spring piece 112. However, the first through-hole 113 needs to meet the requirement of the passing of two pressing arms 131. Therefore, in the present embodiment, the number of a group of first through-holes 113 is two.

[0044] Furthermore, a surface of one end of the pressing member 13 away from the elastic sheet 112 is not higher than a surface of the upper housing 12 away from the main housing 11 .

[0045] It can be understood that the surface of one end of the pressing member 13 is not higher than the surface height of the upper shell 12 on the same side, which reduces the protruding part of the pressing member 13 on the outside, prevents collision and damage, and avoids non-professionals from misoperating the pressing member 13.

[0046] Specifically, in order to ensure that the pressing member 13 is not mistakenly operated by non-professionals, identification instructions, such as icons, text or color identification, can be added to the upper shell 12 to remind the public the correct way to use the pressing member 13.

[0047] Furthermore, the pressing member 13 includes two pressing arms 131 arranged opposite to each other, a protrusion 133 is provided on one side of the pressing arm 131 close to the inner wall of the second through hole 121, a sliding groove 122 is provided on the inner wall of the second through hole 121 corresponding to the protrusion 133, and the sliding groove 122 cooperates with the protrusion 133 to enable the pressing member 13 to slide in the first through hole 113 and the second through hole 121.

[0048] Specifically, the two pressing arms 131 are used to apply pressure. The pressing arms 131 abut against the spring 112 through the second through-hole 121, thereby realizing the transmission of force from the pressing member 13 to the spring 112. The sliding groove 122 in the second through-hole 121 provides sliding space for the pressing member 13 and provides a limiting fixation for fixing the pressing member 13 in the upper shell 12.

[0049] Furthermore, in order to achieve a more stable connection between the pressing member 13 and the upper shell 12, a group of protrusions 133 and the slide grooves 122 can be correspondingly provided on the sides of two adjacent slide grooves 122 in the second through hole 121 and on the sides of two adjacent protrusions 133 on the pressing member 13 to cooperate with the slide grooves 122, so as to achieve a stable connection between the pressing member 13 and the upper shell 12 and make the sliding of the pressing member 13 smoother.

[0050] Specifically, the two groups of protrusions 133 and the sliding grooves 122 slide simultaneously.

[0051] It can be understood that by pressing the pressing piece 13, the wire can be connected and clamped. This wiring method is simple to operate, can miniaturize the connector 1, is easy to operate, can achieve fast wiring, and has a simple structure and low cost.

[0052] For further information, see Figure 3 The pressing member 13 further includes a connecting arm 132 connecting the two pressing arms 131 , and a pressing groove 1321 is provided on a side of the connecting arm 132 away from the pressing arm 131 .

[0053] It can be understood that the pressing groove 1321 is used to provide a convenient interface for external tools (such as a screwdriver), providing an implementable tool for electricians to apply force.

[0054] Specifically, the external tool may be a screwdriver, a wrench or other tool that is convenient for applying force. To match various types of screwdrivers, such as a flat-head screwdriver, a Phillips screwdriver or a Pozidriv screwdriver, the shape and depth of the pressing groove 1321 can be adjusted in combination with the specific screwdriver shape, allowing the use of specific tools for pressing.

[0055] Furthermore, when processing the side surface of the pressing member 13 on which the pressing groove 1321 is provided, ergonomics should be considered as much as possible to make the use of the pressing member 13 more intuitive and safe for non-professionals. For example, the pressing member 13 can be distinguished from other functional parts of the upper shell 12 through tactile or color design, or some locking or protection can be added to the pressing member 13 to provide an additional protection mechanism to ensure that the pressing member 13 can only be pressed or moved under correct operating conditions.

[0056] Furthermore, the spring piece 112 includes a support portion 1123 abutting against the inner wall of the wiring channel 111 and a first bent portion 1121 disposed at the end of the support portion 1123, and an angle a (such as Figure 2 The pressing member 13 can pass through the first through hole 113 and abut against the first bent portion 1121 by setting the included angle a) in the middle.

[0057] Furthermore, a second bending portion 1122 is provided at the other end of the support portion 1123 relative to the first bending portion 1121, a limiting portion 1124 is provided on the second bending portion 1122, a trigger 14 is provided near the wiring channel 111, one end of the trigger 14 abuts against the limiting portion 1124, an operating groove 123 is opened on the upper shell 12 corresponding to the trigger 14, and the trigger 14 passes through the operating groove 123 and abuts against the limiting portion 1124.

[0058] Furthermore, the second bending portion 1122 and the supporting portion 1123 form an angle b (such as Figure 2 The angle b) is set.

[0059] Furthermore, a conductive member 114 is further disposed in the main housing 11 , and two ends of the conductive member 114 are respectively in contact with the first bending portion 1121 and the second bending portion 1122 .

[0060] Furthermore, the connection point where the conductive element 114 abuts against the first bending portion 1121 is defined as the first connection point A (eg Figure 2 A), the connection point where the conductive member 114 abuts against the second bending portion 1122 is the second connection point B (such as Figure 2 B).

[0061] Specifically, the conductive member 114 is symmetrically arranged at two ends abutting against the first bending portion 1121 and abutting against the second bending portion 1122 .

[0062] It can be understood that when the electrician applies force to the pressing member 13 at one end of the first bent portion 1121 through an external tool, the pressing member 13 slides down under the force, and the pressing arm 131 of the pressing member 13 passes through the first through hole 113 and abuts against the first bent portion 1121. The first bent portion 1121 is deformed under the force, and the angle a (such as Figure 2The angle a) in the diagram decreases, and simultaneously with the decrease in angle a, the first bend 1121 and the first connection point A of the conductive member 114 are separated and no longer connected, thereby creating a gap for the wire to enter. At this time, the wire to be connected can be connected to the wiring channel 111. When the electrician releases the pressing member 13, the good elastic potential energy of the spring 112 will cause the second bend 1122 to return to its original position, that is, the angle a increases to its original size, and the first bend 1121 and the first connection point A of the conductive member 114 are reconnected together, and the first bend 1121 and the conductive member 114 jointly clamp the wire entering the wiring channel 111.

[0063] The wiring operation at one end of the second bent portion 1122 is similar. When the electrician performs wiring operation on the trigger 14, the trigger 14 is lifted upward, and the trigger 14 abuts against the limit portion 1124 of the second bent portion 1122, and the pressure on the second bent portion 1122 toward the support portion 1123 is transmitted to the second bent portion 1122, so that the second bent portion 1122 is deformed, that is, the angle b between the second bent portion 1122 and the support portion 1123 (such as Figure 2 b) in the figure decreases, and at the same time as the angle decreases, the second bent portion 1122 separates from the second connection point B of the conductive member 114, creating a gap for another wire to enter. When the trigger 14 stops being pulled, the second bent portion 1122 of the spring 112 will rebound to its original position, and the angle b (as Figure 2 b) in the figure increases back to the original angle, and the second bent portion 1122 is reconnected with the second connection point B of the conductive member 114 to clamp the wire entering the wiring channel 111, and the wire is connected and clamped by lifting the trigger 14.

[0064] Furthermore, the portion where the pressing member 13 abuts against the first bending portion 1121 is inclined.

[0065] Specifically, in this embodiment, the abutment portion where the pressing arm 131 on the pressing member 13 abuts against the first bending portion 1121 is inclined relative to the first bending portion 1121 to increase the contact area between the pressing arm 131 and the first bending portion 1121, so that when the pressing member 13 is pressed, the pressing arm 131 and the first bending portion 1121 fit better, do not slide, and are easier to operate.

[0066] Furthermore, a clearance notch 1141 is formed at one end of the conductive member 114 abutting against the first bending portion 1121 , and the pressing arm 131 passes through the clearance notch 1141 and abuts against the first bending portion 1121 .

[0067] Specifically, in this embodiment, the conductive member 114 is fixed on one side of the main shell 11 close to the upper shell 12, and is a sheet-like electrical element with a conductive function. The first bent portion 1121 and the second bent portion 1122 abut, approach or move away from the conductive member 114 by pressing the pressing arm 131 or pulling the trigger handle 14. When no force is applied, the first bent portion 1121 and the second bent portion 1122 abut against the conductive member 114 to tightly clamp the wire to achieve electrical connection between the incoming wire and the outgoing wire.

[0068] It can be understood that the conductive member 114 is arranged closer to the upper shell body 12 relative to the spring sheet 112, and the pressing arm 131 passes through the clearance gap 1141 of the conductive member 114 and abuts against the first bent portion 1121, so that the pressing member 13 does not contact the conductive member 114 and thus does not apply force to the conductive member 114, so as to effectively make the first bent portion 1121 and the conductive member 114 stay away from, approach or abut, and protect the good electrical performance of the conductive member 114.

[0069] It can be understood that in this embodiment, the size and shape of the clearance gap 1141 are not specifically limited. It is only necessary that the pressing arm 131 can pass through the clearance gap 1141 of the conductive member 114 and abut against the first bending portion 1121 without applying any force to the conductive member 114.

[0070] Furthermore, the wiring channel 111 includes a second wiring port 124 close to the trigger 14 . The upper housing 12 covers the second wiring port 124 and defines a second opening 125 corresponding to the second wiring port 124 .

[0071] Furthermore, the wiring port at one end of the wiring channel 111 close to the first bending portion 1121 is defined as the first wiring port 115, and the wiring port close to the second bending portion 1122 is defined as the second wiring port 124. The upper shell 12 covers the first wiring port 115 and the second wiring port 124, and correspondingly opens a first opening 116 and a second opening 125 for wire access.

[0072] Specifically, the second wiring port 124 and the second opening 125 are disposed at one end of the second bending portion 1122 of the connector 1 , and the second wiring port 124 is adjacent to the limiting portion 1124 , and cooperates with the trigger 14 to complete the wiring task at one end of the second bending portion 1122 .

[0073] It can be understood that when the first bend portion 1121 and the second bend portion 1122 of the spring 112 are in a state without external force, the connection ports of the first wiring port 115 and the second wiring port 124 facing the wiring channel 111 are in a closed state, and the wire cannot easily pass through the first wiring port 115 and the second wiring port 124 into the wiring channel 111. By pressing the pressing member 13 with an external tool such as a screwdriver, the pressing arm 131 abuts against the first bend portion 1121, and a force is applied thereto to deform the first bend portion 1121, and the angle a (such as Figure 2 The angle a) in the second bending portion 1122 is reduced by the force, and the connection A between the conductive member 114 and the first bending portion 1121 is disconnected, resulting in a gap, which connects the first wiring port 115 and the wiring channel 111. At this time, the wire can be easily connected to the first wiring port 115 and transmitted to the wiring channel 111. At the other end relative to the pressing member 13, by pulling the trigger 14, the trigger 14 is pressed against the limiting portion 1124 of the second bending portion 1122, and a force is applied to the second bending portion 1122 to cause it to deform. The angle b (as shown in FIG. 1 ) between the second bending portion 1122 and the supporting portion 1123 Figure 2 The force on the angle b) in the middle is reduced, and the connection B where the conductive member 114 abuts against the second bent portion 1122 is disconnected, resulting in a gap, which connects the second wiring port 124 to the wiring channel 111. At this time, the wire can be easily connected to the second wiring port 124 and transmitted to the wiring channel 111. At this time, the trigger 14 is pulled back to the previous state. At this time, the end of the trigger 14 abutting against the limiting portion 1124 no longer applies a force to the second bending portion 1122, and the angle b between the second bending portion 1122 and the supporting portion 1123 returns to the state when it was not subjected to force before, applying a clamping force to the wire, which can make the wire more stable after being connected to the second wiring port 124, and not easy to fall off from the second wiring port 124 under the influence of external force.

[0074] For further information, see Figure 4 The trigger 14 includes a controlling claw 141, which cooperates with the operating slot 123 to stabilize the trigger 14. The trigger 14 also includes a pulling portion 143 and a top angle 142. The electrician pulls the pulling portion 143 to achieve the top angle 142 abutting against, approaching or moving away from the limiting portion 1124.

[0075] It can be understood that the setting of the limit portion 1124 can effectively limit the range of movement of the trigger 14. When the trigger 14 is pulled, due to the limitation of the limit portion 1124, it can be prevented that the trigger 14 is separated from the two ends of the limit portion 1124 when moving, thereby ensuring that the trigger 14 will never separate from the first bending portion 1121 of the spring 112, and thus it is possible to effectively apply pressure to the first bending portion 1121 by pulling the trigger 14.

[0076] Furthermore, a limiting convex strip 117 is provided on the inner wall of the wiring channel 111 , and the support portion 1123 is at least partially engaged between the limiting convex strip 117 and the inner wall of the wiring channel 111 .

[0077] It can be understood that the limiting convex strip 117 limits the supporting portion 1123 of the spring sheet 112 to prevent the spring sheet 112 from shaking in the main housing 11 when subjected to force, thereby affecting the speed and quality of wiring.

[0078] Optionally, in order to ensure the service life of the spring piece 112 and improve assembly efficiency, the first bending portion 1121, the second bending portion 1122 and the supporting portion 1123 of the spring piece 112 are integrally formed.

[0079] Specifically, the support portion 1123 is arranged parallel to the conductive member 114 and is fixed on a side of the main shell 11 away from the upper shell 12. The conductive member 114 and the main shell 11, as well as the support portion 1123 and the main shell 11, are firmly and tightly fixed, which can effectively prevent the conductive member 114 and the support portion 1123 from shifting when the second bending portion 1122 and the first bending portion 1121 are deformed by force.

[0080] Compared with the prior art, the connector provided by the utility model has the following advantages:

[0081] 1. The connector provided in the embodiment of the utility model comprises a main shell and an upper shell clamped on the main shell. The upper shell and the main shell are the outer shell parts of the connector, which provide protection and support around the internal components. A spring sheet is arranged in the main shell. When the wiring operation is performed, the pressing piece on the upper shell is pressed to drive the pressing arm to abut against the spring sheet, so that it is deformed by force, and the spring sheet will be offset away from the original position by a certain distance. At this time, one of the wires to be connected is placed in the main shell. When the pressing stops, the spring sheet will rebound to its original position, thereby squeezing the wire placed in the original position of the spring sheet to connect and clamp the wire. The second perforation helps the electrician to operate the pressing piece, provides a pressing space, and provides a limit fixation for fixing the pressing piece in the upper shell. The first perforation provides a contact space for the pressing piece to press against the spring sheet. The wiring method is simple to operate and can be set on a small connector, which is convenient to operate, and has a simple structure and low cost.

[0082] 2. In the connector provided in the embodiment of the utility model, the pressing piece is arranged in the second through hole of the upper shell, and the end surface of the pressing piece away from the spring sheet can be parallel to the end surface of the upper shell away from the main shell or concave than the end surface of the upper shell away from the main shell. The height limitation can reduce the possibility of collision between the pressing piece and other objects, prevent collision and damage, and avoid non-professionals from misoperating the pressing piece. Based on the certain danger of electrical connector technology, the pressing piece can only be pressed by professionally trained electricians using tools, and the height limitation ensures safety.

[0083] 3. In the connector provided in the embodiment of the utility model, the slide groove on the second through hole provides a sliding space for the protrusion on the pressing arm. The cooperation between the protrusion and the slide groove ensures that the pressing piece slides smoothly in the second through hole and realizes precise position control, thereby increasing the fixation of the pressing piece and reducing the risk of loosening and separation.

[0084] 4. In the connector provided in the embodiment of the utility model, the pressing groove is used to allow an external screwdriver to act on the pressing piece, which is convenient for maintenance and adjustment. The connecting arm limits the pressing arm and locks the wiring part in the connector. In actual operation, it is easier to tighten or apply force using a screwdriver or a wrench.

[0085] 5. In the wiring connector provided in the embodiment of the utility model, the spring sheet includes a support portion abutting the connecting channel and a first bent portion arranged at one end of the support portion, the first bent portion and the support portion are arranged at an angle, and the elastic property of the spring sheet enables the first bent portion and the support portion arranged at an angle to still maintain good supporting performance, and can help the support portion better fit the inner wall of the connecting wiring channel to ensure the stability of the connection; when the pressing operation is performed, the pressing arm passes through the first perforation and abuts against the first bent portion, the first bent portion is deformed, and a gap is formed between the first bent portion and the original position, providing a space for the wire to be connected, and in order to make the force on the pressing piece more directly and effectively transmitted to the first bent portion, the side of the pressing arm abutting against the first bent portion is adaptively set to be inclined like the inclined first bent portion, so that the force transmission is more accurate and direct.

[0086] 6. In the wiring connector provided in the embodiment of the utility model, the other end of the support portion relative to the first bending portion is further provided with a second bending portion, the first bending portion and the support portion are arranged at an angle, similarly, the second bending portion and the support portion are also arranged at an angle, and a limiting portion is arranged on the second bending portion. A trigger is arranged near the wiring channel, and when the trigger is pulled, the trigger abuts against the limiting portion of the second bending portion, so that the second bending portion is deformed by force, and when the trigger stops being pulled, the second bending portion of the spring sheet will rebound to its original position, thereby achieving the connection and clamping of the wire.

[0087] 7. The trigger of the connector provided in the embodiment of the utility model includes a control claw and a pull portion. The control claw controls and fixes the position of the trigger between the upper shell and the main shell to ensure that the position of the trigger in the operating slot is stable. The pull portion is a part of the trigger, which passes through the operating slot and is exposed to the outside. The electrician can manipulate the trigger through the pull portion to achieve the plugging, unplugging or locking of the connector. The limit portion abuts against the control claw to limit the movement range of the trigger to ensure that the trigger is in a proper position, making the process of connecting or removing the wire easier to operate. After the wire is connected, it is more stable and not easy to fall off from the channel under the influence of external force. In addition, the trigger is stored in the operating slot, which can make the size of the connector smaller and improve the durability, stability and ease of use of the connector.

[0088] 8. In the wiring connector provided in the embodiment of the utility model, the wiring port is the entrance of the connector, through which the wire or connector can be inserted, the upper shell covers the wiring port, and the opening corresponding to the wiring port allows the wire to pass through. The upper shell protects the wiring port and makes it more convenient to insert the wire. A trigger is set on one side of the second bending part, and the electrician can use the trigger to control another wire of the connector. The trigger is lifted or lowered in the operation slot, and the trigger passes through the operation slot and abuts the limit part to ensure the stability of the trigger and prevent it from swinging excessively or falling off. The trigger makes it easier to operate the process of inserting or removing the wire at one end of the second bending part. After the wire is inserted, it is more stable and not easy to fall out of the channel under the influence of external force. When the trigger is pulled, the trigger abuts the limit part of the second bending part, so that the second bending part is deformed by force. When the trigger stops pulling, the second bending part of the spring will rebound to its original position, thereby realizing the insertion and clamping of the wire. The coordinated design of the trigger and the operating slot makes the process of inserting or removing the wire easier to operate. After the wire is inserted, it is more stable and not easy to fall out of the channel under the influence of external force.

[0089] 9. In the connector provided in the embodiment of the utility model, a conductive member is further provided in the main housing, and the two ends of the conductive member are respectively in contact with the first bend and the second bend. The first bend and the second bend are in contact with, approached or moved away from the conductive member by pressing the pressing arm or pulling the trigger. When no force is applied, the first bend and the second bend are in contact with the conductive member to tightly clamp the wire, thereby realizing the electrical connection between the incoming wire and the outgoing wire.

[0090] 10. The connector provided in the embodiment of the utility model has a limiting convex strip on the inner wall of the wiring channel, which limits the supporting part of the spring piece and makes the connection between the supporting part and the inner wall of the wiring channel more stable, preventing the spring piece from shaking in the main shell when subjected to force, thereby affecting the speed and quality of wiring.

[0091] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
