493303 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 B7 V. Description of the Invention (ii) Technical Field The present invention relates to a connection device used in electrical connection devices such as control devices or switches or terminal blocks. Conventional technology When the electrical equipment is connected with the covered electric wire, the insulation covering layer of the covered electric wire is peeled to expose the conductor, and the conductor is connected to the machine terminal. This type of wire connection has poor workability because it is necessary to peel off the insulation coating. In addition, the conductor (core wire) may be damaged when the insulation cover is peeled off. Terminals for wire connection without peeling off the insulation cover are crimped terminals as shown in Figure 39. The crimping terminal 400 in FIG. 39 is formed with a Y-shaped crimping gap 402 on the terminal plate 401, and a cover wire 300 is placed in the crimping gap 402. The insulation cover 302 covering the wire 300 is cut and pressed. In order to form a structure in which the conductor 301 is connected to the terminal plate 401. However, according to the crimp terminal 400 having the structure shown in FIG. 39, the structure of the cut insulation covering layer 302 is formed by the crimping blade 403 of the crimping gap 402 and the cover wire 300 is inserted. The gap 402 requires a lot of force. Therefore, although the use of radio tweezers or pliers or specialized appliances can be used for crimping the covered wire 300, it is difficult to perform crimping with radio tweezers or pliers and the workability is not good. When special tools are used, since special tools need to be made separately, operators performing crimping work must bring special tools.

Description of the invention (14) The state in the lower position, except for the above posture, the posture of the casing cover 52 in the upper position or the casing cover 52; The posture in the lateral position can also be used. Next, an assembling procedure of the first embodiment will be described. First, the terminal plate 64 of the crimp terminal mold 42 is inserted into the through hole 93 of the housing cover 52, and the crimp terminal mold 42 is mounted on the housing 52 by being embedded in the recess 94 for unknown positioning below. In this installed state, as shown in FIGS. 6 and 7, one portion of the terminal plate 64 is exposed to the outside of the housing cover 52 and can be electrically connected to the terminal plate 64. Further, the stopper piece 92 at the upper end of the terminal holding piece 91 is located above the connecting piece 63 to prevent the crimping terminal die 42 from being pulled out of the housing cover 52. Then, the case body 52 is fitted into the case cover 52, and the crimp terminal mold 42 is set at a predetermined position in the case body 51. In this setting state, one pair of crimping blades 61, 61 of the crimping terminal mold 42 is located at the center of the gap 82 of the guide 81. Therefore, in a state where the recessed portion 17 of the movable member 43 is fitted into the head of the bolt 44, the movable member 43 is fitted into the guide 81 of the housing body 51, and then the bolt 44 is screwed to the crimp terminal mold 42. Bolt holes 1 6 1 to complete the assembly. In this assembled state, by rotating the operation bolt 4 4 using a general tool such as a screwdriver, the electric wire insertion hole 1 8 of the movable member 4 3 can be selectively arranged in one of the crimp terminal molds 4 2. The position above the pair of crimping blades 6 1, 6 1 is opposite to the pair of crimping blades 6 1, 6 1. Therefore, the wire insertion holes 1 8 1, 1 9 1 are arranged on a pair of crimping blades 6 1, 6 1 (Please read the precautions on the back before filling this page) This paper size applies to Chinese National Standard (CNS) A4 Specification (210X297 mm) -17- 493303 A7 B7 V. Above the description of the invention (15), and in the state where the wire insertion hole 1 8 1, 1 9 1 is inserted to cover the wire 300, rotate the bolt 44 and make When the movable member 43 moves (lowers) along the guide 181, the covered electric wire 300 can be pressed against each peripheral edge portion (upper part) of the electric wire insertion holes 181, 191, and pressed into a pair of crimping edges 6 1, 61. At the time of the crimping, the insulating cover of the covered electric wire 300 can be cut by a pair of crimping blades 61, 61, and the conductor is in contact with the pair of crimping blades 61, 61, so that the covered electric wire 300 is connected to the crimp terminal mold 42. . From the above connection state, the bolt 44 is relaxed and the movable member is moved in the reverse direction. Each of the peripheral portions (lower portions) of the wire insertion holes 1 8 1, 1 9 1 which can see 43 can push the covered wire 300 upward, and when it is movable When the member 43 returns to the original position (connecting start position), the cover wire 300 can be completely separated from the pair of crimping blades 6 1, 6 1 and the cover wire 3 can be pulled out from the wire insertion hole 1 8 1, 1 9 1 00. Here, in the present embodiment, at the time of crimping, both the peripheral edges of the electric wire insertion hole 1 8 1 through the inclined portion 72 of the movable member 43 and the electric wire insertion hole 1 9 1 of the pressing portion 73 can be pressed. Since the covered electric wire 300 is pressed into the pair of crimping blades 61, 61, the covered electric wire 300 is not inclined, and can be pressed in a normal state. In addition, since the movable member 43 is provided with the locking pieces 1 8 3, 1 8 3 located on the back side of the guide 81 of the housing body 51, the moment when the covered electric wire 3 00 is pushed in, the The inclined portion 72 of the movable member 43 escapes to the front side, and its movement can also be restricted by the detents 1 8 3 and 1 8 3. According to this embodiment, since the crimping blade 6 1 of the terminal crimping die 47 2 is formed at the front end of the elastic piece 6 2, the crimping blade 6 1 is ejected in the connected state (please read the precautions on the back before filling in this Page) Ordered by the Ministry of Economic Affairs, Intellectual Property, Employee Consumer Cooperatives, and printed paper.
