Description

Plug wire identification structure for wiring terminal

Technical Field

The utility model relates to a plug wire identification structure for a wiring terminal; in particular to a novel identification structure arranged on a terminal shell, which is beneficial to personnel to identify the correct configuration position, specification and other functions of a lead.

Background

It is known in the art to use a metal component (or called a conductive component) and a spring conductor (or called a metal spring) which are encapsulated in an insulating housing (usually made of plastic material) to press or connect a wire entering a terminal, so as to form a terminal device or a wire pressing terminal for electrically connecting or releasing the wire.

Exemplary embodiments of such electrical CONNECTION TERMINALs include configurations that provide for insertion into a circuit board (e.g., a PC circuit board) (e.g., CN 102204015A "electrical CONNECTION TERMINAL," DE 29915515U 1, EP 2325947 a1, etc.), and configurations that provide for mating electrical CONNECTION TERMINALs in an arrangement of mating GROUND tracks (or conductive tracks) to create a common GROUND for electrical or mechanical devices to conduct away residual voltages or static electricity from those machines (e.g., DE 202008015306U 1, US 2013/0143433 a1 "connecting TERMINAL," US 2014/0127932 a1 "ELECTRICAL CONNECTIONTERMINAL," DE 102012009286 a1, US 5362259 "GROUND conductive TERMINAL (GROUND connecting TERMINAL)"), etc.).

Such an electrical coupling terminal (or a rail-type electrical coupling terminal) generally includes an insulating housing; the shell is provided with a wire inlet hole, so that a wire can be inserted into the shell. The housing also defines a cavity for receiving the conductive bracket (or conductive element) and the metal spring, so that the metal spring and the conductive element press the conductive wires inserted into the housing to form contact or electrical connection. The electric connection or contact state of the lead, the metal spring piece and the conductive assembly can not be released unless a person operates other tools to extend into the shell to push the metal spring piece.

One problem with the structure and application of such wire connection terminals is that the prior art connection terminals have serial numbers on the housing to allow the operator to identify the connection terminal (or wire inlet hole) and the corresponding pivoted wire. In practice, according to the arrangement sequence, specification and number of wire-inlet holes of each or multiple terminals, the terminal housing is printed with arrangement numbers (or different color number sequences), such as a1, B2, C3, D4 (yellow 01, green 02, red 03) and so on, so that the user can distinguish the correct position of the wires, the type of wires or the connection relationship between specification and the terminals after installing the terminals and wires, thereby avoiding the situation that the wires are misplaced and the safety is affected.

As known to those skilled in the art, the number provided on the connector housing is not easy for the operator to see and distinguish. This is because the housing is not ideal enough to provide the position or angle at which the numbers are provided; for example, when the serial number is arranged on the plane position of the upper end of the housing in the prior art, the arrangement area is limited, and the sight line is sometimes obstructed by the trip piece or the adjacent trip piece; if the number is set at the vertical plane position of the front end of the housing, the viewing angle of the operator is also not favorable. Particularly, if the personnel can quickly identify the type or specification of the wire, the time for the personnel to repair or remove the obstacle can be effectively reduced.

Representatively, these reference data demonstrate the skill in the art of designing and applying wire bonding terminals or devices in structural combinations; if the re-design considers the combination type of the wire terminal (wire inlet hole) and the related structure, so that the structure is different from the prior art, the use form of the wire terminal (wire inlet hole) can be changed, and the re-design is different from the prior art; substantially, the application thereof will be improved. For example, the structural design of the wire insertion terminal and the wire insertion terminal can provide the identification of the serial number of the terminal or the wire insertion terminal (wire inlet hole), and is beneficial to the observation of an operator and the identification of the correct position, specification type and the like of the wire insertion terminal, thereby improving the conditions that the prior art is easy to misplace, and affects the safety and the obstacle discharge or the maintenance time and the like due to the operation of inserting a plurality of wires. None of these issues are taught or specifically disclosed in the above referenced data.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a main objective provides a plug wire identification structure for binding post promptly, provides effects such as discernment wire correct configuration position, specification type. Comprises a terminal shell and a wire inlet hole (and a tool inlet) arranged on the oblique operation surface of the shell; and arranging an identification structure connected with the oblique operation surface to provide a coding function. The identification structure is provided with a display surface with a mark number; the display surface forms an angle (included angle) with the oblique operation surface along an extension line of the oblique operation surface or along a transverse reference axis, so that personnel identification is facilitated, maintenance time is reduced, fixing operation of operation wires is facilitated, and the problems that in the prior art, a plurality of wires are easily misplaced, safety and maintenance or obstacle removing time are influenced are solved.
