Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector terminal and a connector. Background Art

[0002] A connector is generally a fitting product used to achieve electrical connection. One end is connected to a wire through a terminal, and the other end is connected to a mating plug to transmit electric energy or signals. With the development of the electronics industry, the application range of connectors is increasing; moreover, with the increasing degree of industrial automation and the increasingly strict and precise industrial control requirements, the quality requirements for connectors are also getting higher and higher.

[0003] When a connector is assembled and produced, in order to improve production efficiency, generally the terminal and the housing are processed separately and then plugged together.

[0004] However, in the current stage of connectors, during the assembly and production stage, when the terminal is plugged into the housing, the terminal has a phenomenon of excessive inward insertion, resulting in the terminal bearing a large force. During long-term operation, the terminal is prone to deformation under force, making it difficult to plug in the mating plug, and further causing unstable operation and a risk of poor contact.

[0005] In view of this, a connector terminal and a connector are proposed. Summary of the Utility Model

[0006] The purpose of the utility model is to solve the problem in the prior art that when the terminal is plugged into the housing, the terminal has a phenomenon of excessive inward insertion, resulting in the terminal bearing a large force. During long-term operation, the terminal is prone to deformation under force, making it difficult to plug in the mating plug. A connector terminal and a connector are proposed.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A connector terminal includes a connection block. A plug-in piece is arranged at the top of the connection block, and a fixing piece is arranged at the bottom of the connection block; the plug-in pieces are designed in two groups, and the ends of the two groups of plug-in pieces away from the connection block approach each other; the ends of the two groups of plug-in pieces away from the connection block are in a trumpet shape.

[0009] Preferably, the connection block is L-shaped.

[0010] Preferably, the fixing pieces are designed in two pairs.

[0011] A connector further includes a housing. An installation groove is arranged inside the housing, and a slot is arranged at the top of the housing. The installation groove and the slot are communicated with each other; the plug-in piece is located in the slot.

[0012] Preferably, a clamping block is provided on the side wall of the connecting block, and a clamping groove is provided on the side wall of the housing. The clamping block is clamped in the clamping groove.

[0013] Preferably, a ramp protrusion is provided on the side wall of the installation groove. The ramp protrusion is located below the clamping groove, and the top of the ramp protrusion is flush with the clamping groove.

[0014] Preferably, a limiting plate is provided on the side wall of the connecting block, and a limiting surface is provided in the installation groove.

[0015] Preferably, a chamfer is provided on the outer side of the top of the limiting plate.

[0016] Preferably, a concave surface is provided at the top of the installation groove, and the horn shape is clamped in the concave surface.

[0017] Preferably, clamping plates are provided on both sides of the housing.

[0018] Compared with the prior art, the present utility model provides a connector terminal and a connector, having the following beneficial effects:

[0019] 1. For this connector terminal, through the design that the top of the insertion piece is in a horn shape, it is convenient to insert and remove the plug-in, so that the plug-in will not abut against the top end face of the insertion piece.

[0020] 2. For this connector terminal, through the L-shaped design, the bottom fixing piece can also play a limiting role. After the insertion is completed, the fixing piece is attached to the bottom of the housing, avoiding excessive inward insertion of the terminal, avoiding large forces on the terminal, and preventing the terminal from deforming under force during long-term operation, thereby reducing the risk of poor contact.

[0021] 3. For this connector, when the installation is completed, the connecting block abuts against the limiting surface through the limiting plate at the top, restricting its further upward insertion and avoiding large forces on the connector terminal. Description of the Drawings

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0032] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0033] Embodiment 1:

[0034] Referring to Figures 1 - 3 , a connector terminal includes a connection block 1. An insertion piece 101 is provided at the top of the connection block 1, and a fixed piece 103 is provided at the bottom of the connection block 1. The connection block 1, the insertion piece 101, and the fixed piece 103 are integrally formed; the insertion piece 101 is designed in two groups, and the ends of the two groups of insertion pieces 101 away from the connection block 1 approach each other; the ends of the two groups of insertion pieces 101 away from the connection block 1 are in a flared shape 102. The so-called flared shape 102, as Figure 1 , means that the top opening is large and the bottom opening is small.

[0035] As Figure 3 , the fixed piece 103 is used for fixedly connecting with a wire.

[0036] like Figures 1 - 3 The plug-in is plugged into two groups of plug-in pieces 101 with trumpet-shaped tops 102 to achieve the transmission of electrical energy or signals.

[0037] The trumpet-shaped 102 design of the top of the plug-in piece 101 facilitates plugging and unplugging of the plug-in, so that the plug-in will not abut against the top end surface of the plug-in piece 101.

[0038] like Figures 1 - 3 The connection block 1 is L-shaped. Through the L-shaped design, the connection direction of the bottom wire can be changed so that the wire and the top plug-in are in a vertical relationship to meet specific usage scenarios.

[0039] The L-shaped design can also improve the strength of the terminal, making it less likely to deform under force.

[0040] At the same time, through the L-shaped design, the bottom fixing plate 103 can also play a limiting role. After the connection is completed, the fixing plate 103 is attached to the bottom of the shell 2 to prevent the terminal from being inserted too much inward, and to prevent the terminal from being subjected to a large force, so that it will not be deformed by force during long-term operation, thereby reducing the risk of poor contact.

[0041] The fixing plates 103 are designed in two pairs, each pair is two groups. When fixing the wire, pliers or other tools are used to bring them closer to each other and fix the wire in the middle.

[0042] Embodiment 2:

[0043] Reference Figures 1 - 8 Based on the embodiment 1, a connector is proposed, which further includes a housing 2, wherein a mounting groove 202 is provided in the housing 2. Figure 8 The shape of the mounting groove 202 matches the connector terminal in Example 1. A slot 201 is provided on the top of the housing 2. The mounting groove 202 is connected to the slot 201. The plug-in piece 101 is located in the slot 201.

[0044] During installation, the connector terminal is inserted into the installation slot 202 . At this time, the plug-in piece 101 is located in the slot 201 . During use, the plug-in piece is inserted into the plug-in piece 101 .

[0045] By matching the shape of the mounting groove 202 with the connector terminal, after the terminal is plugged into the housing 2, the side wall of the terminal is in contact with the mounting groove 202. At the same time, the fixing plate 103 is in contact with the mounting groove 202 at the bottom of the housing 2, preventing the terminal from being inserted further inward, and preventing the terminal from being subjected to a large force, so that the terminal will not be deformed by force during long-term operation, thereby reducing the risk of poor contact and further ensuring the stability of the connection between the plug-in and the connector 101.

[0046] like Figure 7 and Figure 8, a clamping block 3 is provided on the side wall of the connecting block 1, and a clamping groove 301 is provided on the side wall of the outer shell 2. The clamping block 3 is clamped in the clamping groove 301; the connecting block 1 and the clamping block 3 are integrally formed.

[0047] When the installation is completed, the clamping block 3 is clamped in the clamping groove 301 to achieve the purpose of self-locking, avoiding the terminal from falling off. Also, when the clamping block 3 is clamped in the clamping groove 301, it indicates that the installation is completed, and then the insertion is stopped to avoid damaging the connector terminal.

[0048] The side wall of the installation groove 202 is provided with a ramp protrusion 302. The ramp protrusion 302 is located below the clamping groove 301, and the top of the ramp protrusion 302 is flush with the clamping groove 301. Through the ramp protrusion 302, when the connector terminal is installed on the outer shell 2, the connecting block 1 is better deformed under force, and then the clamping block 3 is clamped in the clamping groove 301.

[0049] Such as Figures 7 - 8 , a limiting plate 4 is provided on the side wall of the connecting block 1. The limiting plate 4 is located above the clamping block 3; a limiting surface 401 is provided in the installation groove 202. The connecting block 1 and the limiting plate 4 are integrally formed.

[0050] When the installation is completed, the connecting block 1 abuts against the limiting surface 401 through the limiting plate 4 at the top to limit its continuous upward insertion and avoid the connector terminal from bearing a large acting force.

[0051] The outer side of the top of the limiting plate 4 is provided with a chamfer. During insertion, the chamfer plays a guiding role to avoid the limiting plate 4 from abutting against other components inside the outer shell 2.

[0052] Such as Figure 4 、 Figures 6 - 8 , an inner concave surface 5 is provided at the top of the installation groove 202. The bell shape 102 is clamped in the inner concave surface 5.

[0053] The bell shape 102 being clamped in the inner concave surface 5 means that the top of the insertion piece 101, that is, the end face of the bell shape 102, is clamped in the inner concave surface 5, so that when it is inserted with the mating plug, it can effectively prevent the mating plug from abutting against the end face of the bell shape 102, resulting in difficult insertion.

[0054] Such as Figures 4 - 6 , clamping plates 6 are provided on both sides of the outer shell 2. Through the clamping plates 6, the outer shell 2 can be quickly connected to other objects.

[0055] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
