AI Technical Summary
The existing terminals are inconvenient to use in special occasions such as high altitude operations and cannot be crimped twice. Due to the specifications of hydraulic clamps, some cables cannot be crimped normally, and the cables are prone to breakage.
A crimp-free terminal is designed, including a terminal head and a connecting cylinder. A press plate is provided in the connecting cylinder and connected to the press plate through bolts. The connection can be achieved by inserting the cable into the connecting cylinder and tightening the bolts.
A simple connection between the cable and terminals is achieved without hydraulic clamps, supports reuse, adapts to more sizes of cables, and reduces the risk of breakage at cable connections.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wiring terminals, in particular to a crimp-free terminal. Background Art
[0002] The terminal block is a product used to connect cables and electrical appliances. It is connected to the end of the cable so that the cable and electrical components can be connected. The prior art usually involves peeling the end of the cable and inserting it into the connecting barrel of the terminal. The connecting barrel is squeezed and deformed with hydraulic pliers (or similar tools) to achieve a fixed connection between the cable harness and the terminal block. However, such a solution has at least the following shortcomings: (1) This wiring method is very inconvenient to use in special occasions such as high-altitude operations; (2) The crimped terminal block cannot be crimped again after crimping; (3) Due to the specifications of the crimping pliers of the hydraulic pliers, some cables cannot be crimped normally because of their large or small size; (4) The edge of the cable where it is crimped is prone to breakage. In view of the above technical problems, the present application proposes a new technical solution that can achieve the connection between the cable and the terminal without crimping. Utility Model Content
[0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a crimp-free terminal, aiming to solve the technical problem of crimping the connection terminal by pliers in the prior art.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A crimp-free terminal comprises a terminal head and a connecting cylinder, wherein a pressing plate is arranged in the connecting cylinder, one end of the connecting cylinder is connected to the terminal head, and the other end is provided with an opening; a threaded through hole is arranged on the connecting cylinder, a bolt is arranged in the threaded through hole, and the bolt is connected to the pressing plate.
[0006] Furthermore, in the crimp-free terminal, a threaded blind hole is provided on the pressure plate, and the bolt is connected to the threaded blind hole.
[0007] Furthermore, in the crimp-free terminal, the connecting tube includes a top plate, a bottom plate, an end plate, and two side plates, the terminal head is connected to the end plate, and a threaded through hole is opened on the top plate.
[0008] Furthermore, in the crimp-free terminal, the lower surface of the end of the pressure plate facing outward is provided with a first inclined surface inclined upward, and the upper surface of the end of the bottom plate facing outward is provided with a second inclined surface inclined downward.
[0009] Furthermore, in the crimp-free terminal, the connecting cylinder and the terminal head are integrally formed.
[0010] Beneficial effects: The present invention provides a crimp-free terminal, which has at least the following advantages compared to the prior art: (1) when connecting a cable and the crimp-free terminal, there is no need to use hydraulic pliers or the like to squeeze the connecting tube, and the bolt can be directly tightened, making the operation easier; (2) the crimp-free terminal can be reused; (3) the same size of crimp-free terminal can be adapted to cables of more sizes; (4) the connection between the cable and the crimp-free terminal is not easy to break. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 3 This is a bottom view of the pressure plate. DETAILED DESCRIPTION
[0014] The utility model provides a crimp-free terminal. To make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0015] See also Figures 1 to 3 The utility model provides a crimp-free terminal. The accompanying drawings are only used to explain the structural principles and are not proportional to the actual product. The accompanying drawings only depict structures related to the invention of this application, and some conventional structures are not specifically depicted. For the sake of ease of explanation, this article inevitably uses some directional words, but these directional words are not intended to limit this application, because they can be set to different directions in actual applications.
[0016] A crimp-free terminal comprises a terminal head 1 and a connecting barrel 2, wherein a pressing plate 3 is arranged in the connecting barrel; one end of the connecting barrel ( Figure 1 and Figure 2 The right end in the middle) is connected to the terminal head, and the other end ( Figure 1 and Figure 2 The left end of the connecting tube is provided with an opening; a threaded through hole is provided on the connecting tube, and a bolt 4 is provided in the threaded through hole, which is connected to the pressure plate.
[0017] In practical applications, a gasket 5 is also provided between the bolt and the connecting cylinder. The terminal head is provided with a through hole for connecting with an electrical component, which is a prior art and is not specifically limited here.
[0018] Preferably, the connecting tube comprises a top plate 21, a bottom plate 22, an end plate 23, and two side plates 24, the terminal head is connected to the end plates, and the threaded through hole is opened on the top plate. This arrangement makes the connecting tube simple in structure as a whole.
[0019] Preferably, the lower surface of the outward end of the pressing plate is provided with a first inclined surface 31 inclined upward, and the upper surface of the outward end of the bottom plate is provided with a second inclined surface 221 inclined downward. When the cable is inserted into the connecting tube, the two inclined surfaces can play a good guiding role, so that the cable can be smoothly inserted into the connecting tube.
[0020] Preferably, the connecting cylinder and the terminal head can be integrally formed by casting, stamping or the like.
[0021] Preferably, the lower surface of the pressing plate is provided with anti-skid patterns 39. By providing the anti-skid patterns, the friction between the cable and the lower surface of the pressing plate can be increased to ensure that the cable is not easy to loosen from the connecting tube. Figure 3 A solution for anti-slip patterns (including a plurality of arc protrusions and line segment protrusions) is provided, but the practical application is not limited thereto.
[0022] During actual use, insert the cable into the connecting tube and tighten the bolts so that the pressing plate presses the cable tightly.
[0023] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
