Description

[Technical Field]

[0001] The present disclosure relates to the technical field of electrical connectors, and more particularly to connector terminals and electrical connectors. [Background technology]

[0002] Vehicle components have very high reliability requirements. To ensure the safety of vehicles during operation under complex road conditions and extreme circumstances, reliable electrical connections between vehicle components must be ensured. Vehicle components are connected to each other via connectors. Therefore, the connector's terminal structure must ensure a stable and reliable electrical connection between the male and female terminals by maintaining reliable contact during severe vibrations and in complex environments. The male and female terminals of a connector are typically fixed within the connector's sheath via a catch spring. The catch spring abuts against a stop portion of the sheath to prevent the terminals from moving within the receiving cavity, thereby ensuring a good connection between the male and female terminals and enhancing the connector's stable and reliable electrical connection.

[0003] However, existing connector terminal catch springs, especially those for small terminals, have a problem of relatively low strength. In harsh operating environments involving long-term low- and high-frequency vibrations, the relatively low strength of the catch springs is easily affected by external forces, resulting in bending fracture of the catch springs and loosening of the terminals. Summary of the Invention [Problem to be solved by the invention]

[0004] SUMMARY OF THE INVENTION To solve the problem that the strength of the catch spring structure of existing connector terminals is low and the stability of the electrical connection is affected, the present disclosure provides a connector terminal and an electrical connector. [Means for solving the problem]

[0005] The technical solutions adopted in this disclosure to solve the above technical problems are as follows:

[0006] According to one aspect, the present disclosure provides a connector terminal, the connector terminal comprising: an insertion-mating portion; a catch spring disposed on an outer surface of the insertion mating portion, Fixed section, and an abutment section having one end connected to the fixed section and the other end being a free end, the fixed section being connected to the insertion mating portion, the abutment section gradually moving away from the insertion mating portion in a direction extending from the fixed section to the free end of the abutment section; a catch spring including: a catch spring reinforcement structure, wherein at least one side of the fixing section is connected to the catch spring reinforcement structure in a width direction of the connector terminal; Includes.

[0007] In some embodiments, both sides of the fixing section may be connected with the catch spring reinforcement structure in the width direction of the connector terminal.

[0008] The end of the fixing section that connects with the insertion mating portion is the first end, the end of the fixing section that connects with the abutment section is the second end, and the distance between the fixing section and the insertion mating portion gradually increases from the first end to the second end in the height direction of the connector terminal, forming a smooth slope that transitions to the abutment section.

[0009] In some embodiments, the catch spring reinforcement structure is at least one of a structure recessed in a direction toward the inside of the insertion mating portion and a structure protruding in a direction facing away from the insertion mating portion.

[0010] In some embodiments, the catch spring reinforcement structure includes a connecting portion, a transition portion, and a contraction portion that are sequentially connected to the side surfaces of the fixed section in a direction from the first end toward the second end of the fixed section. The connecting portion and the transition portion are both arc-shaped plate structures that protrude in a direction facing away from the insertion mating portion.

[0011] In some embodiments, one end of the connecting portion may be connected to an outer surface of the insertion mating portion, and the other end of the connecting portion may be connected to an end of the transition portion.

[0012] In some embodiments, both the connecting portion and the transition portion are arcuate plate structures that are curved in a direction toward the insertion mating portion.

[0013] In some embodiments, the end of the transition portion connected to the contraction portion is the third end. The end of the transition portion connected to the connection portion is the fourth end. The transition portion gradually moves away from the insertion mating portion from the third end to the fourth end in the height direction of the connector terminal. The contraction portion may be connected between the transition portion and the abutment section. The contraction portion is in the shape of a plate that extends obliquely along the transition portion to the abutment section.

[0014] In some embodiments, the insertion mating portion, the catch spring, and the catch spring reinforcement structure are integrally formed.

[0015] In some embodiments, the abutment section is an elongated sheet structure. The length of the abutment section ranges from about 1.5 mm to about 3.2 mm. The width of the abutment section ranges from about 0.5 mm to about 1.4 mm.

[0016] In some embodiments, the included angle between the extension direction of the abutment section and the length direction of the connector terminal ranges from about 5° to about 60°.

[0017] In some embodiments, the interlocking portion is a hollow strip-like structure.

[0018] In some embodiments, the head end of the insertion mating portion is disposed as an opening in the length direction of the connector terminal. The resilient contact arm may be disposed within an inner cavity of the insertion mating portion.

[0019] In some embodiments, the connector terminal further includes an extension section, a conductive press-fit portion, and an insulating press-fit portion. One end of the extension section is connected to the tail end of the insertion mating portion. The insulating press-fit portion is disposed on the other end of the extension section. The conductive press-fit portion is disposed on the extension section. The conductive press-fit portion is positioned between the insulating press-fit portion and the insertion mating portion.

[0020] According to another aspect, the present disclosure provides an electrical connector including a housing and the aforementioned connector terminal. The housing is provided with a receiving cavity configured to receive the connector terminal. The receiving cavity is provided with a stop portion on an inner wall. When the connector terminal is inserted into the receiving cavity, the abutment section abuts against the stop portion to prevent the connector terminal from moving within the receiving cavity.

[0021] According to the connector terminal provided in the present disclosure, due to the structurally weak position of the catch spring, a catch spring reinforcing structure is provided on both sides of the fixed section. When the catch spring is subjected to external action, the catch spring reinforcing structure effectively supports the fixed section, which improves the structural strength of the fixed section of the catch spring. In this way, problems of bending fracture or tearing caused by the relatively low strength of the fixed section of the catch spring are prevented. In addition, problems of deformation and breakage caused by low-frequency and high-frequency vibrations of the catch spring in complex environments can be prevented, and movement of the connector terminal can be prevented, thereby improving the reliability and stability of the electrical connection of the electrical connector.

[0023] The following detailed description illustrates the general principles of the present disclosure, examples of which are further illustrated in the drawings, in which like reference symbols indicate identical or functionally similar elements.

[0024] In order to make the technical problems, technical solutions, and beneficial effects to be solved in the present disclosure more comprehensible, the present disclosure will be described in more detail below with reference to drawings and embodiments. It should be understood that the specific embodiments described herein are not intended to limit the present disclosure, but are merely used to clarify the present disclosure.

[0025] In describing the present disclosure, it should be understood that the terms "head end" and "tail end" are orientation limitations based on the operational state of the insertion mating portion. For example, the end of the insertion mating portion for inserting another electrical device is the head end of the insertion mating portion, and the end of the insertion mating portion for connecting with an electrical wire is the tail end of the insertion mating portion. However, these terms are used merely to facilitate and simplify the description of the present disclosure, and do not indicate or imply that the referenced device or element needs to have a particular orientation or be configured and operated in a particular orientation. Therefore, these terms should not be understood as limitations on the present disclosure.

[0026] In the description of this disclosure, the "length direction," "width direction," and "height direction" of the connector terminal are based on the "length direction," "width direction," and "height direction" labeled in Figures 1 and 2.

[0027] 1 and 2 , one embodiment of the present disclosure provides a connector terminal 1, which includes an insertion mating portion 11, a catch spring 12, and a catch spring reinforcement structure 16. The catch spring 12 is disposed on an outer surface of the insertion mating portion 11. The catch spring 12 includes a fixed section 122 and an abutting section 121. One end of the abutting section 121 is connected to the fixed section 122. The other end of the abutting section 121 is a free end. The fixed section 122 is connected to the insertion mating portion. At least one side of the fixed section 122 is connected to the catch spring reinforcement structure 16 in the width direction of the connector terminal. The abutting section 121 extends gradually away from the insertion mating portion 11 in a direction from the fixed section 122 toward the free end of the abutting section 121.

[0028] As shown in Fig. 3, due to the structurally weak position of the catch spring 12, catch spring reinforcing structures 16 are provided on both sides of the fixed section 122. When the catch spring 12 is subjected to an external action, the catch spring reinforcing structures 16 effectively support the fixed section 122, which improves the structural strength of the fixed section 122 of the catch spring 12. In this way, problems of bending fracture or tear caused by the relatively low strength of the fixed section 122 of the catch spring 12 are prevented. In addition, problems of deformation and breakage caused by low-frequency and high-frequency vibrations of the catch spring 12 in complex environments can be prevented, and movement of the connector terminal 1 can be prevented, thereby improving the reliability and stability of the electrical connection of the electrical connector.

[0029] In one embodiment, both sides of the fixing section may be connected with the catch spring reinforcement structure in the width direction of the connector terminal.

[0030] In one embodiment, the catch spring 12 is located on any side wall of the insertion mating portion 11 rather than on the end portion.

[0031] 4 and 5, in one embodiment, the end of the fixed section 122 connected to the insertion mating portion 11 is the first end. The end of the fixed section 122 connected to the abutting section 121 is the second end. The distance between the fixed section 122 and the insertion mating portion 11 gradually increases from the first end to the second end in the height direction of the connector terminal 1, forming a smooth slope transition to the abutting section 121.

[0032] The fixed section 122 is used as an extension of the abutting section 121 and is configured to connect the abutting section 121 to the insertion mating portion 11. Furthermore, during insertion of the connector terminal 1 into the accommodating cavity 21 of the housing 2, the fixed section 122 is elastically deformed so that the catch spring 12 approaches the outer surface of the insertion mating portion 11. After the connector terminal 1 is inserted into the accommodating cavity 21 of the housing 2, the elastic deformation of the fixed section 122 is restored, and the abutting section 121 is pushed out to restrict the connector terminal 1. In addition, when the connector terminal 1 is subjected to an external force, the abutting section 121 directly transmits the force to the fixed section 122. The fixed section 122 supports the abutting section 121. Therefore, the structural strength of the fixed section 122 is directly related to the structural strength of the catch spring 12.

[0033] In one embodiment, with respect to the position of the fixed section 122, the catch spring reinforcement structure 16 is at least one of a structure recessed in a direction toward the inside of the insertion mating portion 11 and a structure protruding in a direction facing away from the insertion mating portion 11.

[0034] The placement of a recessing or protruding structure in cooperation with the fixed section 122 helps to improve the structural strength of the fixed section 122 .

[0035] In some embodiments, the catch spring reinforcement structure 16 includes a connecting portion 161, a transition portion 162, and a contraction portion 163, which are connected in sequence. The connecting portion 161, the transition portion 162, and the contraction portion 163 are connected to the side surfaces of the fixed section 122 in a direction from the first end toward the second end of the fixed section 122. The connecting portion 161 and the transition portion 162 are both arc-shaped plate structures that protrude in a direction facing the side opposite the insertion coupling portion 11.

[0036] In one embodiment, one end of the connecting portion 161 may be connected to the outer surface of the insertion mating portion 11. The other end of the connecting portion 161 may be connected to the end of the transition portion 162.

[0037] In one embodiment, both the connecting portion 161 and the transition portion 162 are arc-shaped plate structures bent in a direction toward the insert mating portion 11. One side of the connecting portion 161 may be connected to the fixed section 122. The other side of the connecting portion 161 may be bent in a direction toward the insert mating portion 11. One side of the transition portion 162 may be connected to the fixed section 122. The other side of the transition portion 162 may be bent in a direction toward the insert mating portion 11.

[0038] In one embodiment, the end of transition portion 162 connected to constricted portion 163 is the third end. The end of transition portion 162 connected to connecting portion 161 is the fourth end. Transition portion 162 gradually moves away from insertion mating portion 11 from the third end toward the fourth end in the height direction of connector terminal 1. Constricted portion 163 may be connected between transition portion 162 and abutting section 121. Constricted portion 163 is in the shape of a plate that extends obliquely along transition portion 162 to abutting section 121.

[0039] The connecting portion 161 and the transition portion 162, which are arc-shaped plate structures, enhance the overall strength of the fixed section 122. The transition portion 162 and the abutting section 121 smoothly transition through the contracted portion 163. In the structure of the catch spring 12 having equal length, equal width, and equal thickness, the catch spring 12 having the connecting portion 161, the transition portion 162, and the contracted portion 163 is used as the catch spring reinforcing structure 16, which can greatly improve the strength of the catch spring against bending.

[0040] In one embodiment, the insertion mating portion 11, the catch spring 12, and the catch spring reinforcement structure 16 are integrally formed.

[0041] In some embodiments, the insertion mating portion 11, the catch spring 12, and the catch spring reinforcing structure 16 are obtained by processing the same metal blank, which may be one or more selected from copper or its alloy, aluminum or its alloy, iron or its alloy, nickel or its alloy, and magnesium or its alloy.

[0042] In another embodiment, the insertion mating portion 11, the catch spring 12, and the catch spring reinforcement structure 16 may alternatively be segmented structures.

[0043] In one embodiment, the abutment section 121 is an elongated sheet structure. The length of the abutment section 121 ranges from about 1.5 mm to about 3.2 mm. The width of the abutment section 121 ranges from about 0.5 mm to about 1.4 mm.

[0044] In some embodiments, the "length of the abutment section 121" is indicated by the identifier L in FIG. 4. The "width of the abutment section 121" is indicated by the identifier W in FIG.

[0045] In one embodiment, the angle included between the extension direction of the abutment section 121 and the length direction of the connector terminal ranges from about 5° to about 60°.

[0046] In some embodiments, the "angle included between the abutment section 121 and the outer surface of the insert mating portion 11" is indicated by the identifier a in Figure 5. The catch spring 12 is disposed on the top outer surface of the insert mating portion 11. The angle included between the abutment section 121 and the outer surface of the insert mating portion 11 is the angle included between the abutment section 121 and the top outer surface of the insert mating portion 11.

[0047] In one embodiment, the interlocking portion 11 is a hollow strip-like structure.

[0048] In one embodiment, the interlocking portion 11 is a hollow strip thin-wall structure formed by winding wire.

[0049] In some embodiments, as shown in FIG. 2, a sheet metal piece may be bent along multiple bend lines to obtain the insertion mating portion 11. The direction from the head end to the tail end of the insertion mating portion 11 is used as the preset direction. The bend lines of the insertion mating portion 11 are parallel to the preset direction. By setting the number of bend lines and the bend angle, the insertion mating portion 11 can be obtained with different cross-sectional shapes, such as a male terminal shape or a female terminal shape.

[0050] 1 and 2, in one embodiment, the insertion mating portion 11 is a female terminal. In the longitudinal direction of the connector terminal 1, the head terminal of the insertion mating portion 11 may be arranged as an opening, and the elastic contact arm 111 may be arranged in an inner cavity of the insertion mating portion 11.

[0051] The resilient contact arm 111 and the insertion mating portion 11 are integrally formed. The resilient contact arm 111 is placed at an edge position of the blank before the insertion mating portion 11 is bent, and is rolled and inserted into the inner cavity of the insertion mating portion 11 by bending. One end of the resilient contact arm 111 may be fixed at an open position of the insertion mating portion 11. The other end of the resilient contact arm 111 may be deflected toward the inner cavity of the insertion mating portion 11 so as to be suspended in the middle of the inner cavity of the insertion mating portion 11 to form a resilient structure. An arc-shaped bent portion 1111 may be formed on the resilient contact arm 111. A male terminal configured to be fitted to the insertion mating portion 11 is provided with a protrusion. When the male terminal is inserted into the cavity of the insertion mating portion 11, the protrusion comes into resilient contact with the arc-shaped bent portion 1111 of the resilient contact arm 111, thereby establishing an electrical connection.

[0052] In another embodiment, the insertion mating portion 11 may alternatively be a male terminal. A groove-like structure is provided on a female terminal that is matched to the insertion mating portion 11. An electrical connector is disposed within the groove-like structure. The insertion mating portion 11 is inserted into the groove-like structure and abuts against the corresponding electrical connector to establish an electrical connection.

[0053] 2 , in one embodiment, connector terminal 1 further includes extension section 13, conductive press-fit portion 14, and insulating press-fit portion 15. One end of extension section 13 may be connected to the tail end of insertion mating portion 11. Insulating press-fit portion 15 may be disposed on the other end of extension section 13. Conductive press-fit portion 14 may be disposed on extension section 13. Conductive press-fit portion 14 is disposed between insulating press-fit portion 15 and insertion mating portion 11.

[0054] The conductive press-fit portion 14 includes a first press-fit portion 141 and a second press-fit portion 142. The insulating press-fit portion 15 includes a third press-fit portion 151 and a fourth press-fit portion 152. The first press-fit portion 141 and the second press-fit portion 142 are disposed on opposite sides of a middle portion of the extension section 13 in a substantially V-shape. The first press-fit portion 141 and the second press-fit portion 142 are configured to be compressed adjacent to each other to secure the conductive portion of the wire. The third press-fit portion 151 and the fourth press-fit portion 152 are disposed on opposite sides of a tail end of the extension section 13 in a substantially V-shape. The third press-fit portion 151 and the fourth press-fit portion 152 are configured to be compressed adjacent to each other to secure the insulating portion of the wire.

[0055] The extension section 13 is a thin-walled strip structure having a substantially U-shaped cross section. The extension section 13 is obtained by extending rearward from the tail end of the insertion mating portion 11. The first press-fit portion 141 and the second press-fit portion 142 are respectively placed on two side walls of the extension section 13 and extend outward. The third press-fit portion 151 and the fourth press-fit portion 152 are respectively placed on two side walls of the tail end of the extension section 13 and extend outward. In the extension direction of the extension section 13, the third press-fit portion 151 and the fourth press-fit portion 152 are staggered.

[0056] During use, connector terminal 1 must be electrically connected to an electrical wire. The electrical wire (not shown) includes a conductive portion at a front end from which the insulating skin is stripped and an insulating portion at a rear end wrapped with the insulating skin. The conductive portion and a portion of the insulating portion are received in a groove in extension section 13. The conductive portion is positioned between first press-fit portion 141 and second press-fit portion 142. The insulating portion is positioned between third press-fit portion 151 and fourth press-fit portion 152. First press-fit portion 141 and second press-fit portion 142 are bent inward toward each other to form a clamping and electrical connection function for the conductive portion. Third press-fit portion 151 and fourth press-fit portion 152 are pressed closely together to surround the outer surface of the insulating portion to form a fixing function on the insulating portion.

[0057] In one embodiment, the first press-fit portion 141, the second press-fit portion 142, the third press-fit portion 151, and the fourth press-fit portion 152 each have a sheet-like fin structure.

[0058] In one embodiment, the angle between the first press-fit portion 141 and the second press-fit portion 142 ranges from about 120° to about 150° to facilitate attachment and fixation of the conductive portion of the electrical wire.

[0059] In one embodiment, the angle between the third press-fit portion 151 and the fourth press-fit portion 152 ranges from about 120° to about 150° to facilitate attachment and fastening of the insulated portions of the wire.

[0060] In one embodiment, the extension section 13, the first press-fit portion 141, the second press-fit portion 142, the third press-fit portion 151, the fourth press-fit portion 152, and the insertion mating portion 11 are integrally formed.

[0061] 6 , another embodiment of the present disclosure provides an electrical connector including a housing 2 and the aforementioned connector terminal 1. The housing 2 is provided with an accommodating cavity 21 configured to receive the connector terminal 1. An inner wall of the accommodating cavity 21 is provided with a stop portion 22. When the connector terminal 1 is inserted into the accommodating cavity 21, the abutting section 121 can abut against the stop portion 22 to prevent the connector terminal 1 from moving within the accommodating cavity 21.

[0062] The electrical connector has relatively good electrical performance through the aforementioned connector terminal 1. The catch spring 12 provides higher positional restraint strength to prevent deformation and damage of the catch spring 12 caused by low-frequency or high-frequency vibration of the connector terminal 1, thereby ensuring the reliability and stability of the electrical connection of the electrical connector.

[0063] In one embodiment, a through hole communicating with the stop portion 22 may be provided on the side wall of the housing 2. When the connector terminal 1 needs to be pulled out of the accommodating cavity 21, the abutment section 121 of the catch spring 12 can be compressed through the through hole to move the abutment section 121 of the catch spring 12 away from the stop portion 22, thereby disabling the restricting function for the connector terminal 1.

[0064] Although the present disclosure has been described in detail with reference to its preferred embodiments, the preferred embodiments are not intended to limit the present disclosure. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present disclosure shall fall within the protection scope of the present disclosure.
