Technical Field
[0001] The utility model relates to the technical field of electrical equipment, in particular to a plug terminal assembly and a plug. Background Art
[0002] The plug terminal assembly is an important component of the plug, which plays a role in connection and conduction. The plug terminal assembly usually includes a terminal and a plug, wherein the terminal is fixedly arranged on one side of the plug, and the terminal has a threaded hole for installing a fastening screw and a through hole for wiring. When wiring, the wire is inserted into the through hole, and the wire is pressed against the terminal by twisting the screw to achieve conduction. Since the wire is in direct contact with the terminal instead of the plug, the terminal not only needs to be made of a material with good conductive properties (such as copper), but also needs to have a corresponding conductive part, which increases the preparation cost. Utility Model Content
[0003] The utility model provides a plug terminal assembly and a plug, which can overcome the problems existing in the related technology and reduce the preparation cost.
[0004] Specifically, the following technical solutions are included:
[0005] On the one hand, an embodiment of the utility model provides a plug terminal assembly, comprising: a terminal, a plug and a wiring crimping piece;

[0008] The first end of the wiring crimping piece passes through the terminal body and enters the wiring channel, so that a crimping space is formed between the first end and the partial surface of the protruding portion.
[0009] In a possible implementation manner, the protruding portion has a fixing hole, and the connecting portion can be inserted into the fixing hole.
[0010] In a possible implementation manner, a dimension of the connecting portion in a width direction of the protruding portion is reduced relative to that of the terminal body.
[0011] In a possible implementation manner, the connecting portion has a guide surface, and the guide surface is located on a side of the connecting portion away from the terminal body.
[0012] In a possible implementation, the connecting portion includes a first protrusion and a second protrusion, and the first protrusion and the second protrusion are sequentially arranged in an extending direction of the protruding portion.
[0013] In a possible implementation, the terminal body has a through hole communicating with the wiring channel, and the first end of the wiring crimping piece passes through the through hole and enters the wiring channel.
[0014] In a possible implementation manner, the wiring crimping member is a screw, and the through hole is a threaded hole.
[0015] In a possible implementation, the wiring crimping piece and / or the terminal include iron material.
[0016] In a possible implementation manner, an extending direction of the protruding portion is perpendicular to an extending direction of the latch body.
[0017] In a possible implementation, the thickness of the protruding portion is smaller than the thickness of the latch body.

DETAILED DESCRIPTION
[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] In order to make the technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.
[0034] In related technologies, such as Figure 1As shown, the plug terminal assembly includes a terminal 1 and a plug 2, wherein the terminal 1 is fixedly arranged on one side of the plug 2. Furthermore, the terminal 1 has a through hole a, the axial direction of the through hole a is the same as the width direction of the plug 2, and is used to insert the wire. The terminal 1 also has a threaded hole b, the threaded hole b is connected to the through hole a, and the axial direction of the threaded hole b is the same as the length direction of the plug 2. The threaded hole b is used to install a fastening screw, so that the fastening screw is crimped on the terminal 1 by the fastening screw after passing through the threaded hole b and entering the through hole a. When in use, the current flows from the plug through the terminal to the wire. In order to meet the electrical conductivity requirements between the plug and the wire, the terminal not only needs to be made of a material with good electrical conductivity (such as copper), but also needs to have a corresponding conductive part, which makes the preparation cost in the related art relatively high.
[0035] In order to solve the problems existing in the related art, the embodiment of the utility model provides a plug terminal assembly. Figure 2 , Figure 2 The present invention provides a schematic structural diagram of a plug terminal assembly provided in an embodiment of the present invention. The plug terminal assembly comprises: a terminal 1, a plug 2 and a wiring crimping piece 3.
[0036] The plug 2 includes a plug body 21 and an extension portion 22 . The extension portion 22 is located at one side of the body 21 and connected to the plug body 21 for connecting to the terminal 1 .
[0037] The terminal 1 comprises a terminal body 11 and a connecting portion 12 , wherein the connecting portion 12 connects the terminal body 11 with the extending portion 22 , and a wiring channel 13 is formed between the terminal body 11 and the extending portion 22 , wherein a partial surface of the extending portion 22 forms a partial channel wall of the wiring channel 13 .
[0038] The first end 31 of the wiring crimping piece 3 passes through the terminal body 11 and enters the wiring channel 13, thereby forming a crimping space 14 between the first end 31 and a partial surface of the protruding portion 22, so that after the wire (not shown in the figure) passes through the wiring channel 13, it is crimped to the protruding portion 22 at the crimping space 14 by the first end 31 of the wiring crimping piece 3.
[0039] In this way, when the plug terminal assembly provided by the embodiment of the utility model is in use, the wire is located in the crimping space 14 and is in direct contact with the plug 2 under the pressing action of the first end 31 of the wiring crimping piece 3. Therefore, there is no need to select a material with good conductive properties (such as copper) for the terminal 1, but it can be made of a material with poor conductive properties but low cost such as iron, and there is no need to set up a corresponding conductive part, thereby reducing the preparation cost.
[0040] The structure of the plug terminal assembly provided by the embodiment of the utility model is described in detail below:
[0041] As for the terminal 1, the terminal 1 plays a role in providing contact pressure.
[0042] In some embodiments, the shape of the terminal 1 can be square, polygonal, etc., which can be selected according to actual conditions and is not specifically limited in the embodiments of the present utility model.
[0043] For example, see Figure 3 ,in Figure 3 This is a schematic structural diagram of a terminal in a plug terminal assembly provided by an embodiment of the utility model, wherein terminal 1 is a square terminal.
[0044] In some embodiments, the terminal 1 includes iron material. Compared with the terminal 1 in the related art that is made of copper, the cost of iron material is lower, so the preparation cost of the terminal 1 of the present invention can be effectively reduced.
[0045] In some embodiments, see Figure 3 The terminal body 11 has a through hole 15 communicating with the wiring channel 13 , so that the first end 31 of the wiring crimping piece 3 passes through the through hole 15 and enters the wiring channel 13 .
[0046] In order to facilitate the formation of the crimping space 14 between the first end 31 of the wire crimping piece 3 and a portion of the surface of the protruding portion 22 , the axial direction of the through hole 15 may be perpendicular to the extending direction of the protruding portion 22 .
[0047] See also Figure 2 and Figure 3 The connecting portion 12 is located at one side of the terminal body 11 and is used to connect the terminal body 11 with the extending portion 22 of the plug 2 .
[0048] In some embodiments, the terminal body 11 and the connecting portion 12 are integrally formed. Of course, the terminal body 11 and the connecting portion 12 can also be separately prepared and then connected, which is not specifically limited in the embodiments of the present utility model.
[0049] In some embodiments, in order to realize the connection between the terminal body 11 and the extension portion 22, see Figure 2 and Figure 3 The extending portion 22 has a fixing hole 221 , and the connecting portion 12 can be inserted into the fixing hole 221 .
[0050] In some embodiments, see Figure 3 , the dimension of the connecting portion 12 in the width direction of the extending portion 22 becomes smaller relative to the terminal body 11 .
[0051] In this way, the required preparation materials for the connection portion 12 can be reduced, which is beneficial for saving preparation materials and reducing preparation costs.
[0052] In some embodiments, see Figure 2 and Figure 3 The connecting portion 12 includes a first protrusion 121 and a second protrusion 122, wherein the first protrusion 121 and the second protrusion 122 are sequentially arranged in the extending direction of the extending portion 22, and the first protrusion 121 and the second protrusion 122 are matched and connected with the fixing hole 221 to ensure the firmness of the connection.
[0053] Understandably, see Figure 2 There are two fixing holes 221 , which are arranged in sequence in the extension direction of the protruding portion 22 and correspond to the first protrusion 121 and the second protrusion 122 respectively, so that the first protrusion 121 can be inserted into one fixing hole 221 , and the second protrusion 122 can be inserted into the other fixing hole 221 .
[0054] In some embodiments, see Figure 3 The connecting portion 12 has a guiding surface 123 , and the guiding surface 123 is located on a side of the connecting portion 12 away from the terminal body 11 , so as to play a guiding role when the connecting portion 12 is inserted into the fixing hole 221 .
[0055] As for the plug 2, the plug 2 plays a role of conducting electricity.
[0056] In some embodiments, the material of the plug 2 is copper.
[0057] In some embodiments, see Figure 4 ,in Figure 4 This is a schematic diagram of the structure of a plug in a plug terminal assembly provided in an embodiment of the utility model. The extension direction of the extension portion 22 is perpendicular to the extension direction of the plug body 21. In other words, the plug body 21 and the extension portion 22 are in an "L" shape, which is convenient for fixing the terminal 1 on the extension portion 22.
[0058] In some embodiments, see Figure 4 , the thickness of the extension 22 is less than the thickness of the plug body 21. Since the thickness of the plug body 21 needs to meet the industry standard, while the thickness of the extension 22 does not, by setting the thickness of the extension 22 to be less than the thickness of the plug body 21, the preparation material of the plug 2 can be saved while meeting the requirement of supporting the fixed terminal 1, thereby saving the preparation cost.
[0059] In some embodiments, see Figure 4 The latch 2 further includes an arc-shaped connecting portion 23 , through which the latch body 21 and the extending portion 22 are connected.
[0060] By providing the arc-shaped connecting portion 23 , the stability of the connection between the latch body 21 and the extending portion 22 can be ensured.
[0061] For the wiring crimping piece 3, the wiring crimping piece 3 plays a role in providing contact pressure.
[0062] In some embodiments, see Figure 2 , the wiring crimping part 3 can be a screw.
[0063] In order to cooperate with the screw, the through hole 15 of the terminal body 11 can be a threaded hole.
[0064] In the related art, in order to ensure that the terminal has good electrical conductivity, the terminal is usually made of copper, that is, the terminal is a copper terminal, and correspondingly, the screw also needs to be a copper screw. If an iron screw is used, the copper terminal will be screwed off due to the softness of the copper material, resulting in connection failure. In the embodiment of the utility model, the wire and the plug 2 are in direct contact, so the electrical conductivity of the terminal does not need to be considered.
[0065] In the embodiment of the utility model, the terminal 1 and the wire crimping piece 3 can both be made of iron, that is, the terminal 1 is an iron terminal and the screw is an iron screw. In this way, using the same material can not only make the terminal withstand greater torque and facilitate tightening, but also the preparation cost of the terminal and the screw is lower than that of the copper terminal and the copper screw in the related art, which is conducive to saving preparation cost.
[0066] Based on the above scheme, the terminal 1 and the wiring crimping part 3 only provide contact pressure and do not need to have good conductive properties. The conductivity of the plug terminal assembly is provided by the plug 2 that directly contacts the wire. The terminal 1 and the wiring crimping part 3 can be made of materials with poor guiding properties but low cost such as iron, so that the preparation cost of the overall plug terminal assembly is greatly reduced.
[0067] The embodiment of the utility model further provides a plug, which includes the plug terminal assembly as mentioned in the above embodiment.
[0068] By adopting the plug terminal assembly as described in the above embodiments, the manufacturing cost of the plug can be reduced.
