Description
Technical Field
[0001] This invention relates to the technical field of automotive connector terminals, and in particular to an automotive connector terminal capable of reducing positive force attenuation. Background Technology
[0002] Connectors are crucial electronic components in automobiles, playing a vital role in transmitting current and signals. The conductivity of a connector affects the functionality of electrical components within the vehicle and can even impact driving safety. A connector consists of a plug and a socket, which typically include sheaths, terminals, and other parts. The terminals, usually made of metal, are essential components for enabling the connector's function. Terminals include male and female terminals, and the connector achieves its conductivity through stable contact between these terminals.
[0003] With the development of new energy vehicles and intelligent vehicles, high-voltage connectors and high-speed transmission connectors have gradually emerged. However, the most widely used connectors in vehicles are still low-voltage connectors, and the terminal type is mainly the chip terminal. Connector terminals can be divided into crimping area, transition area and electrical connection area according to their functional areas. The electrical connection area is the position where the male terminal and the female terminal are inserted, that is, the position of the terminal engagement system.
[0004] When connectors mate, the internal elastic structure of the metal terminals undergoes elastic deformation. The positive force of the terminal contact has a significant impact on the reliability of the connector contact and the assembly performance. Optimizing the positive force can improve the problem of transient signal interruption when the connector vibrates, reduce the terminal contact impedance, and improve the terminal assembly performance.
[0005] Existing automotive connectors often operate in high-temperature environments and require repeated mating and unmating. Under thermal fatigue and mating fatigue, the stress release in the terminal materials leads to significant attenuation of the positive force, resulting in a substantial decrease in electrical contact performance. Therefore, optimizing the terminal structure to reduce positive force attenuation and ensure excellent conductivity of the connector terminals is of great significance for connector terminal development. Summary of the Invention
[0006] To address the shortcomings in the aforementioned background technology, this invention proposes an automotive connector terminal that can reduce positive force attenuation, thus solving the technical problem that in the prior art connector terminals, after multiple insertion and removal cycles, the positive force attenuation is significant, resulting in a substantial reduction in electrical contact performance.
[0007] The technical solution of the present invention is implemented as follows: an automotive connector terminal capable of reducing positive force attenuation includes a female terminal and a male terminal for mating. The female terminal is provided with a contact component that abuts against the male terminal and reduces positive force attenuation. The contact component includes a conductive spring and a supporting spring. One end of the supporting spring abuts against the bottom surface of the conductive spring, and the other end is located on the insertion path of the male terminal. When the female terminal and the male terminal are mated, the top surface of the conductive spring abuts against one end of the electrical connection area on the male terminal, and the supporting spring abuts against the other end of the electrical connection area on the male terminal. The female terminal of this application is provided with a conductive spring and a supporting spring. After the female terminal and the male terminal are inserted, the conductive spring abuts against the male terminal, and one end of the supporting spring provides a positive force to the conductive spring, further reducing the attenuation of the positive force. At the same time, the other end of the supporting spring also abuts against the male terminal, forming two abutments against the male terminal, making the insertion of the female terminal and the male terminal more stable. Even after multiple insertion and removal cycles, one end of the supporting spring can still provide a positive force to the conductive spring, which can reduce the attenuation of the positive force and the electrical contact performance is relatively small. This solves the technical problem in the prior art that the connector terminal will have a large attenuation of positive force and a large reduction in electrical contact performance after multiple insertion and removal cycles.
[0008] Preferably, the male terminal includes a male terminal crimping area, a male terminal transition area, and a male terminal electrical connection area arranged sequentially, all of which are integrally connected; the female terminal includes a female terminal crimping area, a female terminal transition area, and a female terminal electrical connection area arranged sequentially, all of which are integrally connected. The male terminal formed by the integral connection of the male terminal crimping area, male terminal transition area, and male terminal electrical connection area results in higher strength; similarly, the female terminal formed by the integral connection of the female terminal crimping area, female terminal transition area, and female terminal electrical connection area results in higher strength.
[0009] Both the female and male terminals are made of copper alloy strip formed by stamping, and the thickness of the copper alloy strip is approximately 0.25-0.5mm.
[0010] Preferably, the electrical connection area of the female terminal includes a housing and a self-locking claw, which are integrally connected. The conductive spring is integrally connected to the side wall of the housing, and the supporting spring is disposed inside the housing. The integral connection of the conductive spring to the side wall of the housing increases the connection strength between the conductive spring and the housing. The upper surface of the housing on the female terminal is composed of two overlapping copper alloy strips. The thickness of the copper alloy strip is approximately 0.25-0.5mm. The housing is designed to create space for the insertion of the male terminal. The self-locking claw facilitates the fixed connection between the female terminal and the connector housing, ensuring the strength of the connection between the female terminal and the connector housing. The conductive spring inside the housing contacts the electrical connection area of the male terminal, achieving conductivity. One end of the conductive spring is integrally connected to the side wall of the housing, while the other end is suspended, making the conductive spring a cantilever structure. The conductive spring itself has a certain elasticity, thus exerting a certain positive pressure on the male terminal after insertion. In addition, one end of the support spring in this application abuts against the conductive spring, and the support spring further provides positive pressure to the conductive spring, making it easier for the conductive spring to maintain stability against the inserted male terminal.
[0011] Preferably, the conductive spring is inverted V-shaped, and the supporting spring is V-shaped. One end of the V-shaped supporting spring supports the bend of the inverted V-shaped conductive spring, and the other end is located on the insertion path of the male terminal's electrical connection area. The inverted V-shape of the conductive spring is to form a convex contact point on the conductive spring, so as to ensure stable contact between the conductive spring and the male terminal. The V-shape of the supporting spring is to form a convex support point on the supporting spring, so as to facilitate contact and support between the supporting spring and the lower end face of the housing, thereby forming the lever structure of this application.
[0012] Preferably, the support spring includes an integrally connected left support arm and a right support arm. The lever arm length of the left support arm is L1, and the lever arm length of the right support arm is L2, where L2 is 1.5-2 times L1. A support point is located between the left and right support arms, resting on the lower end face of the housing. The setting of L2 being 1.5-2 times L1 ensures that the lever arm length of the right support arm is longer than that of the left support arm, allowing a smaller force applied to the right support arm to exert a larger supporting force on the conductive spring.
[0013] It should be noted that the V-shaped support spring, with one end supporting the bend of the inverted V-shaped conductive spring and the other end positioned on the insertion path of the male terminal's electrical connection area, is designed to ensure that after the male and female terminals are properly inserted, the electrical connection area of the male terminal applies force to the right support arm of the support spring on the female terminal, forming a support point. Based on the lever principle, the left support arm of the support spring on the female terminal generates an upward lever force on the conductive spring, achieving good contact between the conductive spring and the electrical connection area on the male terminal. This ensures minimal assembly force during the insertion of the male and female terminals and good electrical performance after they are properly inserted.
[0014] Preferably, an abutment component is provided inside the housing; the gap between the conductive spring and the upper end face of the housing is δ1, the gap between the supporting spring and the upper end face of the housing is δ2, and the thickness of the electrical connection area on the male terminal is δ, where δ equals δ1 and δ2 is less than δ. The abutment component inside the housing, i.e., the conductive spring is integrally connected to the lower end face of the housing, and the supporting spring is abutted against the lower end face of the housing, is designed so that the assembly resistance is small during the insertion of the male terminal into the female terminal. Simultaneously, when the male terminal is fully inserted into the female terminal, the electrical connection area of the male terminal exerts force on the right support arm of the supporting spring on the female terminal, forming a support point. According to the lever principle, this support point transmits the force through the right support arm of the supporting spring to the left support arm of the supporting spring and the conductive spring, forming a resistance point. That is, the left support arm of the supporting spring on the female terminal generates an upward lever force on the conductive spring, achieving good contact between the conductive spring and the electrical connection area on the male terminal.
[0015] Preferably, the housing contains two abutment components arranged symmetrically; the gap between the two conductive springs is δ1, the gap between the two supporting springs is δ2, and the thickness of the electrical connection area on the male terminal is δ, where δ equals δ1 and δ2 is less than δ. The two abutment components, i.e., the two conductive springs, are integrally connected to the upper and lower surfaces of the housing, respectively, and a supporting spring is abutted on each of the upper and lower surfaces of the housing. The setting of δ equaling δ1 and δ2 being less than δ is to ensure minimal assembly resistance during the insertion of the male terminal into the female terminal. Simultaneously, when the male terminal is fully inserted into the female terminal, the electrical connection area of the male terminal exerts force on the right support arm of the supporting spring on the female terminal, forming a support point. According to the lever principle, this support point transmits the force through the right support arm of the supporting spring to the left support arm of the supporting spring and the conductive spring, forming a resistance point. That is, the left support arm of the supporting spring on the female terminal generates an upward lever force on the conductive spring, achieving good contact between the conductive spring and the electrical connection area on the male terminal.
[0016] Preferably, the left support arm has a first bend at the end furthest from the right support arm, and the right support arm has a second bend at the end furthest from the left support arm. The first bend is adapted to the bend of the inverted V-shaped conductive spring. The first bend is designed to match the bend of the inverted V-shaped conductive spring, ensuring that the left support arm applies sufficient force to the conductive spring. The second bend is designed to prevent the right support arm from directly contacting the electrical connection area of the male terminal, thus avoiding damage to the electrical connection area of the male terminal. The second bend is parallel to the insertion direction of the male terminal to prevent the second bend from contacting the male terminal during insertion.
[0017] Preferably, both the first bend and the second bend are integrally connected to the supporting spring. This integral connection ensures the strength of the connection between the first bend, the second bend, and the supporting spring.
[0018] Preferably, the supporting spring is made of stainless steel. Stainless steel supporting springs not only possess strong stability and sufficient strength, ensuring that the supporting springs of this application can provide long-term support for the conductive springs. The first bend, the second bend, and the supporting spring are all integrally stamped from stainless steel sheet.
[0019] The beneficial effects of this invention are:
[0020] 1. The female terminal of this application is provided with a conductive spring and a supporting spring. After the female terminal and the male terminal are inserted, the conductive spring abuts against the male terminal, and one end of the supporting spring provides a positive force to the conductive spring, further reducing the attenuation of the positive force. At the same time, the other end of the supporting spring also abuts against the male terminal, forming two abutments against the male terminal, making the insertion of the female terminal and the male terminal more stable. Even after multiple insertion and removal cycles, one end of the supporting spring can provide a positive force to the conductive spring, which can reduce the attenuation of the positive force and the electrical contact performance is relatively small.
[0021] 2. The V-shaped support spring in this application, with one end supporting the bend of the inverted V-shaped conductive spring and the other end located on the insertion path of the male terminal's electrical connection area, ensures that after the male and female terminals are inserted, the electrical connection area of the male terminal applies force to the right support arm of the support spring on the female terminal, forming a support point. Based on the lever principle, the left support arm of the support spring on the female terminal generates an upward lever force on the conductive spring, achieving good contact between the conductive spring and the electrical connection area on the male terminal. This ensures minimal assembly force during the insertion of the male and female terminals and good electrical performance after insertion. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] Example 1: An automotive connector terminal capable of reducing positive force attenuation, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the device includes a female terminal 1 and a male terminal 2 that are plugged into each other. The female terminal 1 is provided with a contact component that abuts against the male terminal 2 and reduces the attenuation of the positive force. The contact component includes a conductive spring 1-2 and a supporting spring 1-4. One end of the supporting spring 1-4 abuts against the bottom surface of the conductive spring 1-2, and the other end is located on the insertion path of the male terminal 2. When the female terminal 1 and the male terminal 2 are plugged into each other, the top surface of the conductive spring 1-2 abuts against one end of the electrical connection area on the male terminal 2, and the supporting spring 1-4 abuts against the other end of the electrical connection area on the male terminal 2. The female terminal 1 of this application is provided with a conductive spring 1-2 and a supporting spring 1-4. After the female terminal 1 and the male terminal 2 are inserted, the conductive spring 1-2 abuts against the male terminal 2, and one end of the supporting spring 1-4 provides a positive force to the conductive spring 1-2, further reducing the attenuation of the positive force. At the same time, the other end of the supporting spring 1-4 also abuts against the male terminal 2, forming two abutments against the male terminal 2, making the insertion of the female terminal 1 and the male terminal 2 more stable. Even after multiple insertion and removal cycles, one end of the supporting spring 1-4 can provide a positive force to the conductive spring 1-2, which can reduce the attenuation of the positive force and the electrical contact performance is relatively small. This solves the technical problem in the prior art that the connector terminal will have a large attenuation of the positive force and a large reduction in electrical contact performance after multiple insertion and removal cycles.
[0030] Table 1 shows the statistical data of insertion and extraction force tests conducted under the same conditions on the structure of this application with supporting springs 1-4 inside the female terminal 1 and the existing terminal structure without supporting springs 1-4, compared with the same type of male terminal 2:
[0031]
[0032] Table 2 shows the statistical data of insertion and extraction force tests conducted under the same conditions on the structure of this application with supporting springs 1-4 inside the female terminal 1 and the existing terminal structure without supporting springs 1-4, compared with the same type of male terminal 2:
[0033]
[0034] From the above experimental data statistics tables 1 and 2, it can be directly concluded that the insertion and extraction force of the present application structure with supporting springs 1-4 inside the female terminal 1 is only about 3% higher than that of the existing terminal structure without supporting springs 1-4. However, the insertion and extraction force attenuation is more than 10% lower after ten insertions and extractions. This greatly ensures that the insertion and extraction force attenuation is more than 10% lower when the insertion and extraction force increases slightly. That is, the terminal structure of the present application can reduce the attenuation of positive force when the insertion and extraction force increases slightly.
[0035] Table 3 shows the statistical data of contact resistance tests conducted under the same conditions with the same type of male terminal 2, comparing the structure of this application with the female terminal 1 having a supporting spring 1-4 and the existing terminal structure without the supporting spring 1-4:
[0036]
[0037] The statistics for the contact resistance optimization rate in the above statistics table 3 are shown in Table 4 below:
[0038]
[0039] From the experimental data statistics tables 3 and 4 above, it can be directly concluded that compared with the existing terminal structure without the support spring 1-4, the contact resistance of the present application structure with the support spring 1-4 inside the female terminal 1 is reduced by about 10%, and the contact resistance is reduced by about 15.7% after ten insertions and removals. That is, the contact resistance of the present application structure with the support spring 1-4 inside the female terminal 1 is also significantly reduced after ten insertions and removals, and the reliability is also higher.
[0040] Example 2, based on Example 1, provides an automotive connector terminal capable of reducing positive force attenuation, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the male terminal 2 includes a male terminal crimping area, a male terminal transition area, and a male terminal electrical connection area arranged sequentially, all of which are integrally connected. The female terminal 1 includes a female terminal crimping area, a female terminal transition area, and a female terminal electrical connection area arranged sequentially, all of which are integrally connected. The male terminal 2, formed by the integral connection of the male terminal crimping area, male terminal transition area, and male terminal electrical connection area, has higher strength. Similarly, the female terminal 1, formed by the integral connection of the female terminal crimping area, female terminal transition area, and female terminal electrical connection area, has higher strength.
[0041] Both the female terminal 1 and the male terminal 2 are made of copper alloy strip formed by stamping process, and the thickness of the copper alloy strip is about 0.25-0.5mm.
[0042] Example 3, based on Example 2, provides an automotive connector terminal capable of reducing positive force attenuation, such as... Figure 2 and Figure 4As shown, the electrical connection area of the female terminal includes a housing 1-1 and a self-locking claw 1-3, which are integrally connected. The conductive spring 1-2 is integrally connected to the side wall of the housing 1-1, and the supporting spring 1-4 is disposed inside the housing 1-1. The integral connection of the conductive spring 1-2 to the side wall of the housing 1-1 increases the connection strength between the conductive spring 1-2 and the housing 1-1. The upper surface of the housing 1-1 on the female terminal is composed of two overlapping layers of copper alloy strip. The thickness of the copper alloy strip is approximately 0.25-0.5 mm. The housing 1-1 is designed to create space for the male terminal 2 to be inserted. The self-locking claw 1-3 is designed to facilitate the fixed connection between the female terminal 1 and the connector housing, ensuring the strength of the connection between the female terminal 1 and the connector housing. The conductive spring 1-2 inside the housing 1-1 contacts the electrical connection area of the male terminal 2, achieving conductivity. One end of the conductive spring 1-2 is integrally connected to the side wall of the housing 1-1, while the other end is suspended, making the conductive spring 1-2 a cantilever structure. The conductive spring 1-2 itself has a certain degree of elasticity, thus exerting a certain positive pressure on the male terminal 2 after it is inserted. In addition, one end of the support spring 1-4 of this application abuts against the conductive spring 1-2, and the support spring 1-4 further provides positive pressure to the conductive spring 1-2, making it easier for the conductive spring 1-2 to maintain stability against the inserted male terminal 2.
[0043] Example 4, based on Example 3, provides an automotive connector terminal capable of reducing positive force attenuation, such as... Figure 2 and Figure 4 As shown, the conductive spring 1-2 is inverted V-shaped, and the supporting spring 1-4 is V-shaped. One end of the V-shaped supporting spring 1-4 supports the bend of the inverted V-shaped conductive spring 1-2, and the other end is located on the insertion path of the male terminal electrical connection area on the male terminal 2. The inverted V-shape of the conductive spring 1-2 is to form an outwardly convex contact point on the conductive spring 1-2, so as to ensure stable contact between the conductive spring 1-2 and the male terminal 2. The V-shape of the supporting spring 1-4 is to form an outwardly convex support point on the supporting spring 1-4, so as to contact and support the lower end face of the housing 1-1, thereby forming the lever structure of this application.
[0044] Example 5, based on Example 4, provides an automotive connector terminal capable of reducing positive force attenuation, such as... Figure 2 and Figure 4As shown, the support spring 1-4 includes an integrally connected left support arm and a right support arm. The lever arm length of the left support arm is L1, and the lever arm length of the right support arm is L2, where L2 is 1.5-2 times L1. A support point is located between the left and right support arms, resting on the lower end face of the housing 1-1. The setting of L2 being 1.5-2 times L1 ensures that the lever arm length of the right support arm is longer than that of the left support arm, allowing a smaller force applied to the right support arm to drive the left support arm to exert a larger supporting force on the conductive spring 1-2.
[0045] It should be noted that the V-shaped support spring 1-4, with one end supporting the bend of the inverted V-shaped conductive spring 1-2 and the other end located on the insertion path of the male terminal electrical connection area on the male terminal 2, is designed to ensure that after the male terminal 2 and female terminal 1 are inserted into place, the electrical connection area of the male terminal 2 applies force to the right support arm of the support spring 1-4 on the female terminal 1, forming a support point. Based on the lever principle, the left support arm of the support spring 1-4 on the female terminal 1 generates an upward lever force on the conductive spring 1-2, achieving good contact between the conductive spring 1-2 and the electrical connection area on the male terminal 2. This ensures minimal assembly force during the insertion of the male terminal 2 and female terminal 1, and good electrical performance after the male terminal 2 and female terminal 1 are inserted into place.
[0046] Example 6, based on Example 5, provides an automotive connector terminal capable of reducing positive force attenuation, such as... Figure 2 As shown, an abutment component is provided inside the housing 1-1; the gap between the conductive spring 1-2 and the upper end face of the housing is δ1, the gap between the supporting spring 1-4 and the upper end face of the housing 1-1 is δ2, and the thickness of the electrical connection area on the male terminal 2 is δ, where δ is equal to δ1 and δ2 is less than δ. An abutment component is installed inside the housing 1-1, namely, the conductive spring 1-2 is integrally connected to the lower end face of the housing 1-1. A support spring 1-4 is abutted on the lower end face of the housing 1-1, where δ is equal to δ1 and δ2 is less than δ. This setting ensures minimal assembly resistance during the insertion of the male terminal 2 into the female terminal 1. Simultaneously, when the male terminal 2 is fully inserted into the female terminal 1, the electrical connection area of the male terminal 2 exerts force on the right support arm of the support spring 1-4 on the female terminal 1, forming a support point. According to the lever principle, this support point transmits the force through the right support arm of the support spring 1-4 to the left support arm of the support spring and the conductive spring 1-2, forming a resistance point. That is, the left support arm of the support spring 1-4 on the female terminal 1 generates an upward lever force on the conductive spring 1-2, achieving good contact between the conductive spring 1-2 and the electrical connection area on the male terminal 2. Preferably, the gap between the two support springs 1-4 is δ2 = (δ - 0.2) mm.
[0047] Example 7, based on Example 5, provides an automotive connector terminal capable of reducing positive force attenuation, such as... Figure 4 As shown, two abutting components are provided inside the housing 1-1, and the two abutting components are arranged symmetrically; the gap between the two conductive springs 1-2 is δ1, the gap between the two supporting springs 1-4 is δ2, and the thickness of the electrical connection area on the male terminal 2 is δ, where δ is equal to δ1 and δ2 is less than δ. Two abutment components are installed inside the housing 1-1: two conductive springs 1-2 are integrally connected to the upper and lower ends of the housing 1-1, respectively. A support spring 1-4 is abutted against the upper and lower ends of the housing 1-1, respectively. The setting of δ equal to δ1 and δ2 less than δ is to ensure minimal assembly resistance during the insertion of the male terminal 2 into the female terminal 1. Simultaneously, when the male terminal 2 is fully inserted into the female terminal 1, the electrical connection area of the male terminal 2 exerts force on the right support arm of the support spring 1-4 on the female terminal 1, forming a support point. According to the lever principle, this support point transmits the force through the right support arm of the support spring 1-4 to the left support arm of the support spring and the conductive spring 1-2, forming a resistance point. That is, the left support arm of the support spring 1-4 on the female terminal 1 generates an upward lever force on the conductive spring 1-2, achieving good contact between the conductive spring 1-2 and the electrical connection area on the male terminal 2. Preferably, the gap between the two support springs 1-4 is δ2 = (δ - 0.2) mm.
[0048] Example 8, based on Example 6 or 7, provides an automotive connector terminal capable of reducing positive force attenuation, such as... Figure 2 and Figure 4 As shown, the left support arm has a first bend 1-5 at the end away from the right support arm, and the right support arm has a second bend 1-6 at the end away from the left support arm. The first bend 1-5 is adapted to the bend of the inverted V-shaped conductive spring 1-2. The first bend 1-5 is designed to adapt to the bend of the inverted V-shaped conductive spring 1-2 to ensure that the left support arm applies sufficient force to the conductive spring 1-2. The second bend 1-6 is designed to prevent the right support arm from directly contacting the electrical connection area of the male terminal 2, thereby preventing damage to the electrical connection area of the male terminal 2. The second bend 1-6 is parallel to the insertion direction of the male terminal 2 to avoid contact between the second bend 1-6 and the male terminal 2 when the male terminal 2 is inserted.
[0049] Example 9, based on Example 8, provides an automotive connector terminal capable of reducing positive force attenuation, such as... Figure 2 and Figure 4 As shown, the first bend 1-5 and the second bend 1-6 are both integrally connected to the supporting spring 1-4. The integral connection of the first bend 1-5 and the second bend 1-6 with the supporting spring 1-4 is to ensure the connection strength between the first bend 1-5, the second bend 1-6 and the supporting spring 1-4.
[0050] Example 10, based on Example 9, provides an automotive connector terminal capable of reducing positive force attenuation, such as... Figure 2 and Figure 4 As shown, the supporting spring 1-4 is made of stainless steel. The stainless steel supporting spring not only possesses strong stability and sufficient strength, but also ensures that the supporting spring 1-4 can provide long-term support for the conductive spring 1-2. The first bend 1-5, the second bend 1-6, and the supporting spring 1-4 are all integrally stamped from stainless steel sheet.
[0051] In Example 10, a support spring 1-4 is integrally stamped from a stainless steel sheet. Simultaneously, copper alloy strip is used to stamp out the female terminal 1 and male terminal 2. The female terminal 1 is then bent, with one end of the support spring 1-4 supporting the bent portion of the conductive spring 1-2, and the other end positioned on the insertion path of the male terminal electrical connection area on the male terminal 2. This forms the female terminal 1 of this application. The male terminal 2 is then bent to form the male terminal 2. When the male terminal 2 is inserted into the female terminal 1, the conductive spring 1-2 abuts against the male terminal 2. One end of the support spring 1-4 provides a positive force to the conductive spring 1-2, further reducing the attenuation of the positive force. Simultaneously, the other end of the support spring 1-4 also abuts against the male terminal 2, forming two abutments against the male terminal 2.
