Description

Adapter and structure of wire terminal base capable of combining the adapter

technical field

The present invention relates to a terminal device that provides plug-in connection of electrical wires; in particular, it refers to an adapter structure used in combination with the terminal device to jointly resist an external force, produce a more ideal combination, and achieve easy operation ( or easy disassembly) technique.

Background technique

It is an existing technology to apply a spring or metal piece wrapped in an insulating shell (usually made of plastic material) to press the wire entering the connection terminal to form an electrically connected wire terminal or crimping terminal. For example, US6689955 B2 "CONNECTING DEVICE WITH A CONNECTION SPRING OPERATED BY A CAM" patent case provides a typical embodiment.

This type of wire terminal is provided to be inserted on a circuit board (such as a PC circuit board); it includes an insulating housing with a plurality of through holes, allowing the wires from the machine equipment to be inserted into the housing. The casing also defines a chamber for fitting the spring piece or the metal piece, and forming contact or electrical connection with the wires inserted into the casing. The spring leaf or metal piece includes a head end, which will bite the wire after the wire is inserted into the housing, so that the wire will not easily break away from the contact state with the spring leaf or metal piece or the insulating housing. Unless the operator operates a tool or a screwdriver to extend into the housing and push the head end, the contact state between the wire and the spring leaf or the metal piece can be released. The metal part also has a thinner or narrower pin in a symmetrical shape, so as to be inserted into the pin pin of the circuit board, or to be mutually inserted with the pin pin of another wire terminal.

In order to improve the troublesome situation that personnel must operate a tool or a screwdriver to remove the contact state between the wire and the spring leaf or the metal piece or the insulating shell, the above-mentioned patent is provided with a cam in the insulating shell, which is pressed on the spring leaf or the metal piece; the cam has A handle protrudes out of the casing. Therefore, when a person exerts force to pull the handle, the cam can be pushed or released to control the contact relationship between the metal piece and the wire.

A topic related to the structure of this type of terminal block is that the prior art terminal blocks are molded with front and rear shells (we define the shell with through holes or the direction in which the wire enters the terminal block as the front shell) The shape of the terminal block assembly or finished product is formed by using holes and mortise fittings.

Therefore, when the personnel pull the handle to operate the insertion and withdrawal of the wires or the terminal block assembly is in the vibration situation of the machinery and equipment for a long time, it is easy to cause the left and right housings to gradually crack or loosen from the combined area. , so that the electrical connection relationship between the terminal block and the wire is unstable, shaking, poor contact or loosening occurs.

Another issue related to the manufacture of this type of terminal device is that, according to the number and sequence of through holes of each terminal block, the serial number will be printed on the terminal block or the front case, such as A1, B2, C3, D4 (or 1, 2, 3, 4) ... etc., so that the user can distinguish the position of those wires and the connection relationship between the wires and the through holes of the terminal block after installing the terminal block and wires. In practice, the industry must also prepare printing molds of different sizes for the structures of terminal blocks of different specifications to accommodate and fix the terminal blocks and carry out code printing operations; it also reflects the existence of such printing molds. The case where the cost and volume are relatively large.

In order to improve the above-mentioned loosening of the assembly, the cost of coding operation, and the large size, Taiwan Patent No. 99117547 "Adaptor and Wire Terminal Block Structure with Adapter" provides a feasible embodiment. The embodiment provides an adapter that can be printed or coded; the adapter is provided with protrusions and recesses that press and fix the valleys and ridges of the terminal base (or the terminal housing chamber) to form an integral state.

Typically, these reference data show the design skills of the insulating shell of the wire terminal block and the related combination structure of the wire, spring leaf or metal parts; if the redesign considers the combined structure of the insulating shell of the terminal block, it will The structure is different from those who are used to it, and it will be able to change its use pattern, which is different from the old method; in essence, it will also improve its application situation, maintain its overall stability and clamping ability; and reduce the above mold and manufacturing costs. And the working space is reduced to the minimum as much as possible, or further provide the functions of easier operation and more stable combination.

Contents of the invention

Therefore, the main purpose of the present invention is to provide an adapter and a wire terminal seat structure that can be combined with the adapter, which is a combination of the wire terminal (seat) and the adapter, and provides functions such as easier operation and more stable combination.
