Description

[0001] The present invention relates to the technical field of hand tools and in particular to a crimping tool with storage and exchange function.

[0002] Crimping pliers are primarily used to operate crimp terminals and to connect terminals and wires. Depending on the type of terminal, crimping pliers with different specifications are used. Before crimping, the terminal specifications, as well as the voltage and current, must first be checked. After stripping the wire, the terminal is aligned with the hole provided in the crimping pliers. A terminal can only be crimped through a matching hole. The size of the hole must be precise to prevent the terminal from deforming or jamming.

[0003] As described above, the hole size of conventional crimping pliers is limited and cannot accommodate all terminal specifications. Therefore, crimping pliers currently available on the market are equipped with interchangeable crimping dies (the dies are movable and replaceable, featuring a structure that can be pressed against a terminal). Each die has a hole suitable for a specific terminal. However, users must carry different dies to work with different terminals, which is inconvenient and can easily lead to loss. Therefore, manufacturers should reconsider how to crimp terminals of varying specifications while avoiding the problems of loss and the inconvenience of carrying them.

[0004] The main object of the present invention is to provide a crimping tool that allows the user to conveniently and quickly exchange the appropriate crimping dies for crimp terminals of different specifications and sizes when using crimping tools, whereby the crimping dies can be carried together with the crimping tool without having to store and carry them separately, thus avoiding the problem of loss and furthermore solving the problem known from the prior art that when using conventional crimping tools and crimping dies the crimping dies have to be carried separately, which causes inconvenience to the user and can even lead to the loss of the crimping dies.

[0005] To solve the above problem and to achieve the above advantageous effects, the present invention provides a crimping tool with storage and exchange function, comprising: a plier body having a clamping section and a handle control section, wherein the clamping section and the handle control section are connected to each other, a pivot connection section is provided at the connection point, the handle control section is further provided with several receiving recesses, the openings of the receiving recesses of the handle control section are opposite each other and are aligned with each other, and at least one limiting arrangement is arranged in each receiving recess.the at least one limiting arrangement of a respective receiving recess has a positioning block and a limiting set is arranged on the end face of a respective positioning block facing the bottom surface of the corresponding receiving recess; and several replacement clamping blocks which are movably housed in the corresponding receiving recesses and which are each engaged with the positioning block of the corresponding at least one limiting arrangement, wherein the replacement clamping blocks can be removed from the corresponding receiving recesses and movably attached to the clamping section. Fig. Figure 1 shows a schematic perspective view of a first embodiment according to the present invention; Fig. Figure 2 shows a schematic perspective view according to Fig. 1, in which the first embodiment of the present invention is opened; Fig. Figure 3 shows a schematic view according to the first embodiment of the present invention, in which the replacement clamping blocks are removed; Fig. Figure 4 shows a schematic view along the section line IV-IV according to Fig. 2; Fig. Figure 5 shows a schematic view according to Fig. 4, in which the replacement clamping blocks are removed.

[0006] It will be directed to the Fig. 1, Fig. 2, Fig. 3, Fig. 4 to Fig. 5. Reference is made to the crimping pliers according to the invention, which have a storage and exchange function, are mainly used for clamping crimp terminals of different specifications and sizes and comprise the following: a pliers body 1, which has a clamping section 11 and a handle control section 13, wherein the clamping section 11 and the handle control section 13 are connected to each other, a pivot connection section 12 is provided at the connection point, the clamping section 11 and the handle control section 13 are each located at two ends of the pivot connection section 12, for clamping a crimp terminal the handle control section 13 uses the pivot connection section 12 as a pivot point for controlling the closing and opening of the clamping section 11, the handle control section 13 is further provided with several receiving recesses 2, at least one limiting arrangement 3 is arranged in a respective receiving recess 2,the at least one limiting arrangement 3 of a respective receiving recess 2 having a positioning block 31, a limiting set 32 ​​being arranged on the end face of a respective positioning block 31 facing the bottom surface of the corresponding receiving recess 2, and each positioning block 31 being polygonal and having polygonal faces and polygonal corners, and several replacement clamping blocks 4 being movably housed in the corresponding receiving recesses 2 and each being engaged with the positioning block 31 of the corresponding at least one limiting arrangement 3, wherein the replacement clamping blocks 4 are removable from the corresponding receiving recesses 2 and movably attachable to the clamping section 11.

[0007] Based on the main technique of the present invention described above, the receiving recesses 2 of the handle control section 13 are used to store and provide spare clamping blocks 4 of different specifications, with some of the spare clamping blocks being housed in the receiving recesses 2 and some of the spare clamping blocks being housed in the clamping section 11. In this way, the user can flexibly exchange the spare clamping blocks 4 of different specifications according to the requirements on site. With this method, the user does not need to carry additional spare clamping blocks 4, which can easily be lost, but only needs to place the spare clamping blocks 4 to be used in the corresponding receiving recesses 2. The entire operation is therefore convenient and time-saving.The time saving results from the fact that the user does not have to search for a suitable crimping die as usual, but can remove the replacement clamping blocks 4 directly from the corresponding receiving recesses 2 and insert them into the clamping section 11. The convenience lies in the fact that fewer parts need to be carried. It is sufficient to carry only the plier body 1 (with several interchangeable replacement clamping blocks 4). The control of the plier body 1 can be divided into a closing actuation and an opening actuation. For the closing actuation, only the handle control section 13 needs to be closed, while for the opening actuation, an inward push must first be performed (due to the structural design / composition), whereby an elastic force is generated during the opening process.In the present invention, the limiting set 32 ​​of each positioning block 31 faces the bottom surface of the corresponding receiving recess 2. Since each positioning block 31 exerts a force on the bottom surface of the corresponding receiving recess 2 and engages with the corresponding replacement clamping block 4, all replacement clamping blocks 4 can be accommodated and stored in the corresponding receiving recesses 2 to prevent them from easily falling out. Compared to conventional crimping pliers, which have only a limited number of hole diameters and limited hole diameter specifications, or which require additional interchangeable crimping dies to be carried, the present invention is indeed highly advanced.

[0008] Based on the above description of the main technology of the present invention, further technical features and structures of the present invention will be explained in more detail below. Reference is made to the Fig. 1, Fig. 2, Fig. 3, Fig. 4 to Fig. Reference is made to Section 5. Regarding the design of the handle control section 13 of the present invention, the handle control section 13 further comprises two handles 131, wherein the two handles 131 use the pivot connection section 12 as a pivot point for moving towards or away from each other. In the figures, each handle 131 consists mainly of two plates 133 and an outer rubber casing 134, with receiving recesses 2 being provided; however, the invention is not limited to two plates 133 and an outer rubber casing 134.Furthermore, in the present invention, the two plates 133 of each handle 131 are arranged at a distance from each other, with a positioning block 31 being arranged at a distance between the two plates 133. To form the receiving recesses 2, an outer rubber sleeve 134 encases the respective plates 133, and the sleeve positions of the outer rubber sleeve 134 are designed such that the openings of the receiving recesses 2 are opposite each other and aligned with each other. The receiving recesses 2 are provided on opposite sides of the handles 131, with a curved guide segment 21 being provided at the end of the base surface of each receiving recess 2 located near the pivot connection section 12, and the section of the base surface of each receiving recess 2 located near the pivot connection section 12 being a receiving segment 22.If the user wishes to replace a replacement clamping block 4, they can simply press down on the protruding section of each replacement clamping block 4 with their hand, since part of each block protrudes from the opening of the corresponding receiving recess 2. They can then move the replacement clamping blocks 4, housed in the corresponding receiving recess 2, along the base surface towards the curved guide segments 21. Because the bending direction of each curved guide segment 21 is in the direction of the opening of the corresponding receiving recess 2, the corresponding replacement clamping block 4 rests against and is guided by this curved guide segment 21, gradually protruding from the opening of the corresponding receiving recess 2. In this way, the user can remove the replacement clamping block 4 from the receiving recess 2 and insert it into the clamping section 11.Or the replacement terminal block 4 housed in the clamping section 11 can be replaced, whereby the replaced replacement terminal block 4 can be reinserted into the corresponding receiving recess 2 and stored.

[0009] In summary, based on the description of the replacement clamping block process 4, the at least one limiting arrangement 3 located in a respective receiving recess 2 can be brought into engagement with the replacement clamping block 4 located in this receiving recess 2, so that all replacement clamping blocks 4 can be held stably in the corresponding receiving recesses 2 without impeding the work. It is referred to Fig. 5. Furthermore, the limiting set 32 ​​located in each at least one limiting arrangement 3 consists of an elastic element 321 and a positioning ball 322, wherein each positioning block 31 is attached in the corresponding receiving recess 2 and is provided on one side with an inwardly recessed mounting recess 34, each positioning ball 322 is housed in the mounting recess 34 of the corresponding positioning block 31, and each elastic element 321 is housed in the mounting recess 34 of the corresponding positioning block 31, wherein one end of each elastic element 321 rests on the surface of the corresponding mounting recess 34 and the other end of each elastic element 321 bears elastically against the corresponding positioning ball 322.such that a portion of each positioning ball 322 protrudes from the opening of the corresponding mounting recess 34. Furthermore, the opening diameter of each mounting recess 34 is smaller than the circular diameter of the corresponding mounting recess 34. The positioning balls 322 are housed in the corresponding mounting recesses 34 and are blocked by their openings, with a portion of each positioning ball 322 protruding from the corresponding opening. If the spare clamping blocks 4 are to be removed or stored,To move the replacement clamping blocks 4, the user only needs to apply a slight force and press them. In this way, the engagement between each replacement clamping block 4 and the corresponding at least one limiting arrangement 3 can be released. Furthermore, to adapt to the mechanism of the at least one limiting arrangement 3, each replacement clamping block 4 has a drive section 41 and a clamping-holding section 42. When each replacement clamping block 4 is housed in the corresponding receiving recess 2, part of the drive section 41 of each replacement clamping block 4 protrudes from the opening of the corresponding receiving recess 2.wherein the protruding part of each drive section 41 is available to the user for exerting force and pushing, and the clamping-holding section 42 of each replacement clamping block 4 is movably engaged with the at least one limiting arrangement 3 of the corresponding receiving recess 2.

[0010] Continuing the description above, the engagement between the clamping-holding section 42 of a respective replacement clamping block 4 and the positioning ball 322 of the corresponding at least one limiting arrangement 3 is achieved by the fact that a respective clamping-holding section 42 is provided with an engagement recess 421. When a respective replacement clamping block 4 is housed in the corresponding receiving recess 2, a part of the drive section 41 of a respective replacement clamping block 4 projects out of the opening of the corresponding receiving recess 2, wherein the clamping-holding section 42 of a respective replacement clamping block 4 is movably mounted onto the positioning block 31 of the corresponding at least one limiting arrangement 3, and the part of a respective positioning ball 322 projecting from the opening of the corresponding mounting recess 34 is engaged with the engagement recess 421 of the corresponding clamping-holding section 42.This prevents each replacement terminal block 4 from falling out of the corresponding receiving recess 2. During the replacement process, only a small force is required to release the engagement recess 421 of the clamping-retaining section 42 of each replacement terminal block 4 from engaging with the corresponding positioning ball 322. The corresponding receiving recess 2 can then be removed and inserted into the clamping section 11 to clamp the crimp terminal securely, as shown in [reference]. Fig. 5 shown.
