Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

It is noted that relational terms such as "first" and "second," and the like, may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

The features and properties of the present application are described in further detail below with reference to examples.

Example 1 of the visual wire component of the present invention:

as shown in fig. 1-2, the visual wire making part comprises a wire making frame, and the wire making frame comprises a frame body 11, a wire pressing part 12 and a lens 13.

The frame 11 has a structure as shown in fig. 1, and an overall outer contour thereof is substantially rectangular tube-shaped, in this embodiment, the frame 11 is specifically formed by bending a sheet metal, and based on the orientation shown in fig. 1, as shown in fig. 1, the top wall of the frame 11 is a double-wall, wherein a substantially triangular fastening piece 111 is disposed at an end of one of the upper layers, a fastening groove corresponding to the fastening piece 111 is disposed on a right side wall of the frame 11, and the fastening piece 111 is fastened in the corresponding fastening groove, thereby realizing reliable shaping of the frame 11. The frame 11 is made of sheet metal, which has the advantages of low cost and easy mass production, but in other embodiments, the frame 11 may be manufactured by machining, casting, or other processes.

A wiring passage 113 is provided between the front and rear ends of the frame 11, and in this embodiment, the front end of the wiring passage 113 is used for the wire to be connected to enter, and the rear end is used for the contact 16 to be connected to enter, but in other embodiments, their roles may be reversed. The wiring passage 113 defines a cavity for receiving a wire to be connected and the contact 16 for crimping therebetween.

The wire pressing member 12 is used for pressing the wire and the contact element entering the wiring channel 113, in this embodiment, the wire pressing member 12 specifically adopts a wire pressing screw, as shown in fig. 1, the wire pressing screw in this embodiment has a screw rod 121 and a wire pressing head 122, when in use, the wire pressing head 122 is located in the wiring channel 113 which is wire-framed, and is located at the inner end of the wire pressing screw, and the outer end of the wire pressing screw is provided with an inner hexagonal groove for inserting an inner hexagonal wrench to screw the wire pressing screw; the size of the crimping head 122 is larger than the outer diameter of the threaded rod 121 and can be used to increase the contact area with the corresponding wire or contact 16. The frame 11 is provided with screw holes 112 and through holes 114 on two opposite walls, respectively, in this embodiment, the screw holes 112 are located on the top wall of the frame 11, and the through holes 114 are located on the bottom wall of the frame 11 and are arranged coaxially with the corresponding screw holes 112. The size of the through hole 114 is larger than that of the screw hole 112, so that the crimping screw can pass through the corresponding through hole 114 from the bottom to the top but cannot pass through the corresponding screw hole 112 when assembled, thereby preventing the crimping screw from being escaped from the screw hole 112 upward. The length of the line pressing screw satisfies: when the pressing screw is retracted, the two ends of the pressing screw do not protrude from the outer wall surface of the frame 11, so that when the wire frame needs to be installed into the installation hole 141 of the corresponding insulator (such as embodiment 2 described below), the pressing screw does not interfere with the insulator, and the quick installation of the pressing screw is realized without increasing the structural complexity of the insulator installation hole 141.

The frame 11 is provided with a frame viewing port 115 at the wire pressing position, and whether the wire pressing member 12 presses the wire and the contact in the wire connecting channel 113 in place can be observed through the frame viewing port 115. The frame viewing port 115 is located on one side of the pressing direction of the wire pressing member 12, and in this embodiment, is specifically disposed on the left side wall of the frame 11, and has a rectangular and countersunk structure. Through the frame body viewing port 115, the positions and relative positions of the lead and the contact 16 in the wiring channel 113 can be clearly seen in the process of wire making, and a sufficient re-attaching size is ensured between the lead and the contact, namely, a sufficient distance is reserved between the end part of the lead and the wire pressing piece 12 on the rear side, so that the wire making quality is ensured.

The lens 13 is mounted on the frame viewing port 115 of the frame 11, the condition of the wire and the contact in the wiring channel 113 can be seen through the lens 13, and since the frame viewing port 115 is opened, if the frame viewing port 115 is not processed, the whole or part of the wire may protrude from the frame viewing port 115 in the process of inserting the wire into the wiring channel 113 from the front to the rear, thereby reducing the wire drawing efficiency. In this embodiment, the lens 13 has a structure with a thick middle part and thin four sides, so that the convex edge 131 is formed on the four sides, and the overall shape is just matched with the counter bore structure of the frame viewing port 115, so that the inner wall surface of the middle part of the lens 13 is flush with the inner wall surface of the frame 11 after being installed in place.

In the initial state of the visual wire forming member 18 of the present embodiment, the position of the wire pressing screw is as shown by the wire pressing screw at the back in fig. 1, when the visual wire forming member 18 of the present embodiment is used to form a wire on site, the contact 16 is inserted from the back end of the wiring channel 113, the lead is inserted from the front end of the wiring channel 113, and then the positions of the lead and the contact 16 are observed and adjusted through the frame observation port 115, and the wire on site can be formed by screwing the wire pressing screw.

The size of the insulator viewing port 142 is smaller than the size of the convex edge 131 of the lens 13, so that the lens 13 can be tightly pressed and fixed on the frame body 11 to prevent the lens 13 from falling off.

At a position between the two mounting holes 141, a branching tongue piece 143 for branching different wires to different mounting holes 141 is provided at the front end of the wire insulator 14. The branching tongue piece 143 functions to shunt the lead wires, which helps to improve the wire-making efficiency.

When the visual wire manufacturing component 18 of the embodiment is assembled, the pressing screws on the two wire manufacturing frames are screwed and retracted into the corresponding frame bodies 11, and then the frame bodies 11 are integrally installed in the corresponding installation holes 141; of course, in other embodiments, in order to avoid the wire frame interfering with the wire insulator 14 in the process of entering the mounting hole 141, a groove may be formed on the wall of the mounting hole 141 of the wire insulator 14, in which case the wire pressing screw will not necessarily be able to retract into the frame 11. To facilitate manipulation of the crimping screw, a manipulation hole 144 is also provided in the wall of the wire insulator 14 at a location corresponding to the outer end of the crimping screw. In order to position the respective contact ends, as shown in fig. 5, contact insertion grooves 145 are further provided on the insulator at the front ends of the mounting holes 141.

In other embodiments, the frame may be integrated with the contact.
