Description

Technical Field

[0001] The utility model belongs to the technical field of connection structures, and in particular relates to a composite terminal, a low-voltage connector and a connection assembly for low-voltage connection. Background Art

[0002] The terminal body of the existing connector is generally an integral structure. When the terminal structures are similar, it is difficult to highly standardize the terminal mold due to the structural limitations of the body.

[0003] When terminals with different numbers of pins (contact pieces) are spliced ​​and used, the main body structure itself realizes the connection between different pins of the terminal and meets the requirements of carrying voltage and current. This limits the structure itself and makes it impossible to share terminals with different numbers of pins. It is also difficult to achieve standardization of products with different structures. Utility Model Content

[0004] The utility model aims to overcome the deficiencies in the prior art and provide a composite terminal, a low voltage connector and a connection assembly for low voltage connection, which connect standard terminals together to form the number of terminals required by the product and form the required multi-pin connector.

[0005] In order to achieve the above purpose, the utility model is implemented by adopting the following technical solutions:

[0006] The utility model provides a composite terminal for low voltage connection, comprising a connecting terminal and a plurality of standard terminals.

[0007] The standard terminal is formed by two PINs in a U-shaped connection, and is used to connect and conduct with the mating end;

[0008] The connecting terminal is fixedly connected to a plurality of the standard terminals and is used for connection between the plurality of the standard terminals to achieve direct conduction between the plurality of terminals.

[0009] The effect achieved by the above settings: This product provides a standard terminal with a unified structure, and uses connecting terminals to connect the standard terminals together to form the number of terminals required for the product, thereby playing a connecting role. The standard terminal is a part in which two PINs are connected in a U-shape. The connecting terminal is a part in which the standard terminals are connected and conducted through a piercing structure based on the total number of PINs in the product. This product realizes the connection between multiple standard terminals through connecting terminals, thereby realizing direct conduction between multiple terminals.

[0010] Furthermore, the number of standard terminals is the number of pin terminals required by the low-voltage connector product.

[0011] The above arrangement achieves the following effects: the number of standard terminals can be freely combined to obtain the required number, thus saving costs; standardized components facilitate production without the need to change molds, thus greatly reducing costs.

[0012] Furthermore, a stop structure is provided on the standard terminal, and the stop structure is used for inserting and limiting to prevent the terminal from being PIN-out.

[0013] The effect achieved by the above setting is: the main function is to limit the insertion of the pin terminal and prevent the terminal from retreating.

[0014] Furthermore, the stop structure is a spring sheet arranged on the top surface of the standard terminal.

[0015] The above arrangement achieves the following effects: the spring sheet structure is simple to arrange, easy to operate, and can effectively reduce costs.

[0016] Furthermore, the PIN includes a PIN rod and a widened portion arranged on the PIN rod.

[0017] The above arrangement achieves the following effects: the widened portion is used to enhance the strength of the PIN rod to prevent it from breaking, and at the same time, it can cooperate with the spring stop structure to improve the strength of the standard terminal.

[0018] Furthermore, the standard terminal is a copper standard terminal;

[0019] The connecting terminal is a high-conductivity copper connecting terminal.

[0020] Furthermore, a piercing structure is provided between the connecting terminal and the standard terminal;

[0021] The connection terminal and the standard terminal are in contact with each other through the piercing structure to achieve conduction.

[0022] The effect achieved by the above arrangement is that the connecting terminal is the connecting part of the standard terminal, and the standard terminals are connected mainly through external connection, and the contact position is achieved by piercing. The piercing structure is arranged on the connecting terminal, and the connecting terminal is inserted into the arranged standard terminal, that is, the piercing structure is inserted into the standard terminal to achieve piercing conduction.

[0023] Furthermore, the connection terminal includes a fixing plate and an inverted "convex" card interface opened on one side of the fixing plate, and the card interface is used to embed the PIN rod of the standard terminal;

[0024] An extrusion protrusion is arranged opposite to the opening of the card interface. The spacing between the extrusion protrusions is smaller than the diameter of the PIN rod and is used to achieve puncture conduction with the PIN.

[0025] In a second aspect, the utility model provides a low voltage connector, comprising the composite terminal for low voltage connection as described in the first aspect.

[0026] In a third aspect, the utility model provides a connection assembly, comprising the composite terminal for low-voltage connection as described in the first aspect.

[0027] Compared with the prior art, the utility model has the following beneficial effects:

[0028] When developing 4-pin, 6-pin, 8-pin and other products of this type, the U-shaped structure of the terminal structure itself is difficult to realize the sharing of stamping dies. At the same time, automation also needs to design different cutting and pressing jigs according to different terminal structures. This application is to decompose the terminals of this type of product into standard terminals and connecting terminals. Multiple standard terminals can be connected to form the number of terminals required for the product. Now, only one set of 2-pin U-shaped standard terminals and one set of connecting terminal molds need to be developed to complete the standardization of 4-pin, 6-pin, 8-pin and other structural products.

[0036] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0037] In the description of this embodiment, it should be noted that if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this embodiment and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this embodiment. Example

[0038] This embodiment provides a composite terminal for low voltage connection, such as Figure 3 , 5 As shown, it includes a standard terminal 1 with a unified structure, and a connecting terminal 2 is used to connect the standard terminals 1 together to form the number of terminals required for the product, and plays a connecting role. The standard terminal 1 is as shown in FIG. Figure 1 As shown, the standard terminal 1 is connected as follows Figure 3 shown.

[0039] like Figure 1 , 6 As shown, the standard terminal 1 is a part in which two PINs are connected in a U shape, and the connecting terminal 2 is a part in which the standard terminal 1 is connected and conducted through a piercing structure according to the total number of PINs of the product, and is composed of a copper standard terminal 1 body and a connecting terminal 2.

[0040] like Figure 4 As shown, standard terminal 1 is the number of pin terminals required for low-voltage connector products (usually an even number). Standard terminal 1 is formed by two PIN rods connected in a U shape, with a spring on one side. Figure 4 The main function is to limit the insertion of the pin terminal and prevent the terminal from retreating.

[0041] like Figure 1 As shown, the standard terminal 1 generally comprises a PIN rod (with a rectangular or circular cross section) and a widened portion disposed on the PIN rod, the widened portion being used to enhance the strength of the PIN rod and prevent it from breaking. In this embodiment, the diameter of the PIN rod is 0.6 mm.

[0042] like Figure 2 As shown, the connecting terminal 2 is the connecting part of the standard terminal 1, mainly connecting the standard terminal 1 through external connection, and the contact position is realized by using a piercing structure.

[0043] The connecting terminal 2 is in the shape of a fixed plate, and an inverted "convex" card interface is provided on one side of the fixed plate. The card interface is used to embed the PIN rod of the standard terminal 1. An extrusion protrusion 4 is arranged opposite to the opening of the card interface. The spacing between the extrusion protrusions 4 is slightly smaller than the diameter of the PIN rod, which is 0.5mm in this embodiment, and can achieve a puncture depth of 0.05mm.

[0044] Implementation principle: The connection terminal 2 connects the standard terminal 1 together through a puncture connection method, so that subsequent multiple PIN insertion methods can be combined through the standard terminal 1 and finally connected together through the connection terminal 2, which facilitates the standardized design of this type of product.

[0045] When developing 4-pin, 6-pin, 8-pin and other products of this type, the U-shaped structure of the terminal structure itself is difficult to realize the use of stamping dies. At the same time, automation also requires the design of different cutting and pressing jigs according to different terminal structures. This application is to disassemble the terminals of this type of product into Figure 1 The structure shown can connect N standard terminals 1 to form the number of terminals required for the product. Now, only one set of 2-pin U-shaped standard terminals 1 and one set of molds for connecting terminals 2 need to be developed to complete the standardization of 4-pin, 6-pin, 8-pin and other structural products. Example

[0046] This embodiment provides a composite terminal for low voltage connection and a connection assembly thereof, as follows Figure 1 , Figure 2 Implementation example: The product requires a 6-pin terminal pin. The standard terminals currently used are 3 pairs. These three pairs are standard terminals with exactly the same structure. After inserting the plastic (hidden), these 3 pairs of terminals need to be connected to carry current and voltage. At this time, the external terminals are connected by puncturing (such as Figure 3 ) to achieve connectivity between the three pairs of terminals. Example
