Description

Connector and wire terminal block structure capable of combining the connector

The present invention relates to a terminal device for providing electrical wire insertion and connection; in particular, it refers to a connector structure used in combination with the terminal device to jointly resist an external force, produce a more ideal bonding effect, and achieve easy operation (or Simple disassembly) technology.

It is known in the art to use a spring sheet or a metal piece encapsulated in an insulating housing (usually made of plastic material) to press the wires entering the connection terminals to form electrically connected wire terminals or crimp terminals. For example, US 6689955 B2 "CONNECTING DEVICE WITH A CONNECTION SPRING OPERATED BY A CAM" patent case provides a typical example.

This type of wire terminal is provided for insertion on a circuit board (eg, a PC circuit board); it includes an insulating housing having a plurality of through holes through which wires from machinery and equipment can be inserted into the interior of the housing. The housing also defines a cavity for fitting the spring piece or the metal piece and making contact or electrical connection with the above-mentioned wires inserted into the housing. The spring piece or metal piece includes a head end, after the wire is inserted into the housing, it will bite the wire, so that the wire will not easily leave the contact state with the spring piece or the metal piece or the insulating housing. Unless the operator operates a tool or a screwdriver into the housing to push the head end, the contact state between the wire and the spring or metal piece can be released. The metal piece also has a pin that is thinner or narrower in a symmetrical shape, so as to be inserted on the pin of the circuit board, or to be inserted into the pin of another wire terminal.

In order to improve the troublesome situation that personnel must operate a tool or a screwdriver to release the contact state between the wire and the spring sheet or the metal piece or the insulating shell, the above-mentioned patent case sets a cam in the insulating shell and presses on the spring piece or metal piece; the cam has a A handle extends out of the casing. Therefore, when the person pulls the handle with force, the cam can be pushed or released to control the contact relationship between the metal piece and the wire.

A problem related to the structure of this type of terminal block is that the conventional terminal block uses a mold to form the front and rear shells (we define the shell with through holes or the direction of the wire entering the terminal block as the front shell) form, and then use holes and tenon fitting to form a terminal block assembly or finished product.

Therefore, when personnel operate the insertion and withdrawal of wires by pulling the handle as described above, or when the terminal block assembly is subjected to vibration in the operation of 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 between the terminal block and the wire is unstable, and the situation of 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 order of through holes of each terminal block, serial numbers, such as A1, B2, C3, D4 (or 1, 2, 3, 4) ... etc., so that after installing the terminal block and the wire, the user can distinguish the position of the wire and the connection relationship between the wire and the through hole of the terminal block. In practice, for the structure of various specifications of the terminal block, the industry must also prepare printing molds of different sizes to accommodate and fix the terminal block and implement the code printing operation; it also reflects the cost and cost of such printing molds. Larger size.

In order to improve the situation of loosening of the assembly, the cost of coding operation, and the large volume, the Taiwan Patent No. 99117547 "A Adapter and a Wire Terminal Block Structure with a Adapter" provides a feasible embodiment. The embodiment provides a printable or coded connector; the connector is provided with convex parts and concave parts to press-fit the valleys and ridges of the terminal seat (or the terminal seat groove chamber) to form an integral state.

Typically, these reference materials show the design skills of the insulating housing of the wire terminal block and the related combined structure of the wire, the spring piece or the metal piece; The structure is different from the accustomed one, 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 make the above-mentioned mold, manufacturing The cost and working space are minimized as much as possible, or the function of easier operation and more stable combination is further provided.

The main purpose of this creation is to provide a connector and a wire terminal block structure that can be combined with the connector, which is the combination of the wire terminal (seat) and the connector, which provides the functions of easier operation and more stable combination. The adapter includes a base body and a junction area that connects the base bodies; the base body has a combined portion, a secondary portion, and an extension portion. Corresponding to the connector, at least one wall or one side of the terminal base has a groove chamber and a recess chamber, which can respectively accommodate the joint area and the base body. And, the groove chamber is formed with a positioning part and a sub-positioning part, when the adapter is pressed into the groove chamber and the recessed chamber, the adapter and the terminal seat are fixed into an integral state to jointly resist an external force, resulting in a better performance than the prior art. It is ideal for pressing and binding; at the same time, without using tools, it allows personnel to operate the auxiliary part to facilitate the release of the joint state of the connector and the terminal block.

According to the connector of the present invention and the wire terminal block structure in which the connector can be combined, the bonding area of the connector defines a first side and a second side; the first side and the second side are respectively provided with a convex structure. Also, the base body (or the secondary portion) has a groove and side walls defining the groove, an end wall, and the end wall is provided with the interference portion. The grooves give the base body an elastic (deformation) effect, facilitating the base body to be pressed into or out of the recess of the terminal block.

According to the connector of the present invention and the wire terminal block structure in which the connector can be combined, the recess of the terminal seat is provided with a blocking part, after the substrate enters the recess, the interference part of the substrate is blocked to form a fixation; however, direct operation by personnel is allowed. The secondary part releases the state in which the blocking part blocks the interference part.
