Description

Press-fit clamp with storage and replacement function

The invention is a storage and replacement crimping pliers, specifically a technology applied in the field of hand tools, which mainly provides different specifications of the crimping pliers for accommodating the mouthpieces to facilitate carrying, and is an invention with excellent practicality.

There are many types of crimping terminals. They can be classified into round, flat, and square shapes according to their shapes; power terminals, signal terminals, and ground terminals according to their uses; and copper, aluminum, and alloys according to their materials. There are specially-suitable crimping terminals for connecting different wires and electrical appliances. What we are going to discuss now is the crimping clamp used to drive the crimping terminal. The crimping clamp is mainly used to combine the terminal with the wire. According to the terminal type, crimping clamps of different specifications are used. Before crimping, the specifications and voltage and current of the terminal must be confirmed first. After stripping off the insulating skin, match the terminal to the hole installed on the crimping clamp. The appropriate hole can crimp the terminal. The size of the hole must be accurate so that the terminal does not deform or get stuck.

According to the above, the hole size of the common crimping pliers is limited and cannot accommodate all specifications of terminals. Therefore, the crimping pliers sold and used on the market today are provided with replaceable mouth films (mouth films refer to movable and replaceable crimping film blocks, and the crimping film blocks are provided with a structural design that can press against the terminal). Each mouth film is provided with a hole diameter that matches the use of different terminals. However, users often need to carry all the mouth films with them in operation to use them with different terminals. However, it is really inconvenient to carry multiple mouth films and they are also easy to lose. Therefore, relevant industries must think again about how to have both crimping that can accommodate terminals of different specifications and how to make the mouth films easy to carry and avoid loss.

The main purpose of the present invention is to provide users with a method of conveniently and quickly replacing corresponding oral masks for crimping terminals of different specifications and sizes when using crimping pliers, and to carry the crimping pliers together with the crimping pliers without having to take or carry the crimping pliers separately, thereby avoiding the problem of loss. It is intended to improve the use of crimping pliers and oral masks described in the prior art, in which the oral masks must be carried separately, causing inconvenience to the user and even causing the problem of oral masks being lost.

However, in order to achieve the above-mentioned purpose and effect, the present invention provides a compression clamp with storage and replacement, which includes: A clamp body has a clamping part and a handle part, the clamping part and the handle part are connected to each other and form a hinge part at the connection, and the handle part is further provided with a plurality of receiving grooves, and the grooves of the handle part are corresponding to each other, and at least one limit group is provided in each receiving groove, and at least one limit group in each receiving groove has a positioning block, and a limit kit is provided on an end surface of the positioning block facing the bottom surface of the receiving groove; and a plurality of replacement clamps, which are movably accommodated in each receiving groove and are respectively engaged and combined with each positioning block of the at least one limit group, and each replacement clamp is movably assembled in the clamping part after being pulled out of each receiving groove.

According to the main technology described above, the advantage of the present invention is that the user only needs to carry a single clamp body, and after removing the required replacement clips from the receiving slots according to the on-site operation, each replacement clip is installed in the clamping part, so that the terminals of different specifications and sizes can be crimped. It is convenient and time-saving for the user. There is no need to carry additional replacement clips. As long as each replacement clip is installed in each receiving slot, it can be used. The present invention can be carried together with the clamp body, and there is no need to worry about the loss of the replacement clips. It can be fully applicable to the crimping operation of various terminals. Compared with the crimping clamps with replaceable mouth membranes, which are inconvenient to carry and easy to lose, the present invention does improve the shortcomings of the conventional method and provides users with more convenient operation and replacement. It can be seen that the present invention can be said to be a very practical and progressive invention, which is worthy of promotion by the industry and public disclosure to the public.

The following is a description of the present invention by specific examples. People familiar with this technology can easily understand the other advantages and effects of the present invention from the content disclosed in this manual. The present invention can also be implemented or applied through other different specific examples, and the details in this manual can also be modified and changed in various ways based on different viewpoints and applications. The following implementation method further describes the viewpoint of the present invention in detail, but does not limit the scope of the present invention by any viewpoint.

As shown in the first to fifth figures, the present invention is a storage and replacement crimping clamp, which can be mainly used to clamp crimping terminals of different specifications and sizes, and includes: a clamp body 1, having a clamping portion 11 and a control portion 13, the clamping portion 11 and the control portion 13 are connected to each other and form a hinge portion 12 at the connection, the clamping portion 11 and the control portion 13 are respectively located at the two ends of the hinge portion 12, and the control portion 13 uses the hinge portion 12 as the pivot point to control the opening and closing of the clamping portion 11 and clamp the crimping terminal, and the control portion 13 is further provided with a plurality of accommodating grooves 2, and at least one limit is respectively provided in each accommodating groove 2. The at least one limiting group 3 in each receiving groove 2 has a positioning block 31, and a limiting set 32 is provided on an end surface of the positioning block 31 facing the bottom surface of the receiving groove 2, and each positioning block 31 is a polygon and has a polygonal surface and a polygonal corner; and a plurality of replacement clips 4, which are movably received in each receiving groove 2 and are respectively engaged and combined with each positioning block 31 of the at least one limiting group 3, and each replacement clip 4 is movably assembled to the clamping portion 11 after being pulled out of each receiving groove 2.

According to the main technology described above for the present invention, the receiving slots 2 provided in the control portion 13 are utilized to provide replacement clips 4 of various specifications, some of which can be installed in the receiving slots 2, and some of which can be installed in the clamping portion 11. In this way, the user can replace the replacement clips 4 of different specifications according to the needs of the site. In this way, the user does not need to carry the replacement clips 4 extra. The problem of easy loss can be solved by installing the replacement clip 4 to be used in each receiving groove 2. Therefore, the overall operation is convenient and time-saving. The time-saving effect is that the user does not need to look for a suitable oral mask everywhere as in the past, but can directly remove the replacement clip 4 from each receiving groove 2 and install it in the clamping part 11 for use. The convenience is that the number of items to be carried is reduced. Only a single clamp body 1 (with multiple replacement clips) needs to be carried. The clamp block 4 can be replaced) and the clamp body 1 can be operated. The clamp body 1 can be controlled in a closing operation and an unfolding operation. The closing operation is very simple, and the handle 13 can be directly closed. On the contrary, the unfolding operation must be pressed inward before it can be unfolded (due to the structural design/composition), and an elastic force will be generated during the unfolding process. Therefore, the present invention uses each positioning block 31 With the special design that the limiting kit 32 faces the bottom surface of the receiving groove 2, since each limiting kit 32 exerts force toward the bottom surface of the receiving groove 2 and clamps each replacement clip 4, each replacement clip 4 can be prevented from falling off easily when being installed and stored in the receiving groove 2. Compared with the known crimping pliers that only have a fixed number and specification of hole diameters, or require additional carry-on replaceable oral masks, the present invention is indeed highly advanced.

Based on the above main technical description of the present invention, the other technical features and structures of the present invention are further described below. The design of the control portion 13 of the present invention is shown in the first to fifth figures. The control portion 13 further includes two grips 131. The two grips 131 are close to each other and far away from each other with the hinge portion 12 as the pivot point. The two grips 131 are mainly composed of two plates 133 and an outer rubber sleeve 134 to form the accommodating groove 2, but the two plates 133 and The outer rubber sleeve 134 is limited, and it is explained here that the present invention is that the two plates 133 in each grip 131 are arranged at a distance (as shown in the sixth figure), and each positioning block 31 is arranged at the distance between the two plates 133. Each outer rubber sleeve 134 is respectively covered on each plate 133 to form each receiving groove 2, and the covering position of each outer rubber sleeve 134 makes the notches of each receiving groove 2 correspond to each other; each receiving groove 2 is respectively arranged on the side corresponding to each other of each grip 131, and each The bottom surface of the receiving groove 2 is formed into an arc guide section 21 at one end close to the hinge 12, and the bottom surface of each receiving groove 2 close to the hinge 12 is a receiving section 22. When the user wants to replace each replacement clip 4, because the part of each replacement clip 4 protrudes from the notch of each receiving groove 2, the user can simply hold the protruding part of each replacement clip 4 with his hand and move each replacement clip 4 installed in each receiving groove 2 along the bottom surface of the groove toward the arc guide section 21. Since the arc-bending direction of each arc guide section 21 is toward the notch of each receiving slot 2, each replacement clip 4 will abut against the arc guide section 21, and each arc guide section 21 will guide each replacement clip 4 to gradually reveal the notch of each receiving slot 2, so that the user can remove the replacement clip 4 to be replaced from the receiving slot 2 and install it in the clamping portion 11, or replace the replacement clip 4 already set in the clamping portion 11, and the replaced replacement clip 4 can be installed back into each receiving slot 2 for storage.

In summary, the replacement operation of each replacement clip 4 is described. At least one limiter set 3 located in each receiving slot 2 will be mutually engaged with the replacement clip 4 installed in each receiving slot 2, so that each replacement clip 4 can be stably received in each receiving slot 2 without affecting the construction operation. As shown in FIG. 5, the limiter set 32 in the at least one limiter set 3 is composed of an elastic member 321 and a positioning bead 322. Each positioning block 31 is fixed in each receiving groove 2 and is concave on one side to form a mounting groove 34. Each positioning bead 322 is accommodated in the mounting groove 34 of each positioning block 31, and each elastic member 321 is respectively installed in the mounting groove 34 of each positioning block 31 and one end thereof elastically abuts against the groove surface of the mounting groove 34, while the other end of each elastic member 321 elastically abuts against each positioning bead 322 and makes a part of each positioning bead 322 protrude from the groove opening of the mounting groove 34. The diameter of the slot opening of the mounting slot 34 is smaller than the circular diameter of the mounting slot 34. Each positioning bead 322 is accommodated in each mounting slot 34 and blocked by the slot opening. A portion of each positioning bead 322 protrudes from the slot opening. When each replacement clip 4 is to be removed or stored, only a slight force is required to push each replacement clip 4 to move it. In this way, the clamping combination between each replacement clip 4 and at least one limit set 3 can be released. In addition, each replacement clip 4 is The mechanism matches at least one limit set 3, and each replacement clip 4 further includes a driving portion 41 and a clamping portion 42. When each replacement clip 4 is installed in each receiving slot 2, a portion of the driving portion 41 of each replacement clip 4 protrudes from the notch of each receiving slot 2. The protruding portion of each driving portion 41 can provide a user with force to press and push, and the clamping portion 42 of each replacement clip 4 is used to flexibly clamp at least one limit set 3 in each receiving slot 2.

Continuing with the above description, the clamping portion 42 of each replacement clip 4 and the positioning bead 322 of the at least one limit set 3 are connected by a clamping groove 421 provided on each clamping portion 42. When each replacement clip 4 is installed in each receiving slot 2, a portion of the driving portion of each replacement clip 4 protrudes from the notch of each receiving slot 2, and the clamping portion 42 of each replacement clip 4 is movably sleeved on the positioning block 31 of the at least one limit set 3, and each The portion of the positioning bead 322 protruding from the notch of the mounting slot 34 engages with the engaging groove 421 of each clamping portion 42, so as to prevent each replacement clip 4 from falling out of the receiving slot 2. During the replacement operation, only a slight force is needed to allow the engaging groove 421 of the clamping portion 42 of each replacement clip 4 to be separated from the engaging combination with the positioning bead 322, and then the receiving slot 2 is disassembled and installed on the clamping portion 11 to clamp the crimping terminal, as shown in the fifth figure.
