Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and in particular relates to a low-profile sheet-type contact piece and a connector. Background Art

[0002] Servo motors are engines used to realize component operation and high-precision control in servo systems. Due to the limitations of usage scenarios, the installation space is limited in most cases, and the connectors that need to be matched should be as small as possible. The height of the connector directly determines the overall size of the motor. The existing connector solution uses straight contacts for connection. However, the pins and wires are in the same direction, which makes the overall height of the contact higher and the connector also becomes higher. Summary of the invention

[0003] To solve the above problems, the utility model provides a low-profile sheet contact with a novel structure, so that the sheet contact has a smaller height by arranging the contact part and the wire pressing part on the same side or opposite side of the top plate, thereby meeting the small height requirement of the connector.

[0004] The purpose of the utility model and the technical problem to be solved are achieved by adopting the following technical solutions. A low-profile sheet contact piece proposed in the utility model includes a top plate 1, which is provided with a front section, a transition section and a rear section from front to back, wherein a contact portion 11 is provided on one side of the front section, and a wire pressing portion 10 is provided on one side of the rear section, the contact portion 11 includes two first elastic arms 3 extending downward from both sides of the top plate 1 to form a jack structure, the contact portion 11 also includes a front plate 5 extending downward from the front end of the top plate 1, and the front plate 5 is provided with a second elastic arm 6 for cooperating with an insulator to limit the position; the transition section of the top plate 1 has an angle greater than 90 degrees and less than or equal to 180 degrees with the front section and the rear section.

[0005] The purpose of the utility model and the solution to its technical problems can also be further achieved by adopting the following technical measures.

[0006] The aforementioned low-profile sheet contact is characterized in that the front plate 5 is formed by folding the front end of the top plate 1 downward.

[0007] The aforementioned low-profile sheet contact piece has two sides of the top plate extending downward to form side plates, and the first elastic arm 3 is formed by extending downward from the bottom of the side plate, thereby enhancing the elastic retaining force of the first elastic arm 3 to prevent it from deforming and failing.

[0008] The aforementioned low-profile sheet contact, the bottom of the side panel also extends downward to form a side panel extension portion 4, the first elastic arm 3 is located between the side panel extension portion 4 and the front panel 5, and the anti-sway positioning in the insulator is achieved through the side panel extension portion 4 and the front panel 5, and the side panel extension portion 4 and the front panel 5 can also provide protection for the first elastic arm 3 when the contact is assembled to prevent it from direct contact with the insulator.

[0009] The aforementioned low-profile sheet contact piece, the end of the side plate extension portion 4 is bent in the direction of the other side plate extension portion, thereby further enhancing the strength and holding force of the side plate extension portion 4, making it less likely to deform and having better anti-swaying capability.

[0010] In the aforementioned low-profile sheet contact, the contact portion 11 and the wire pressing portion 10 are distributed on the same side or opposite sides of the top plate 1 .

[0011] In the aforementioned low-profile sheet contact, the rear section of the top plate 1 is offset relative to the front section toward the side where the first elastic arm 3 is located, so that the height of the contact is substantially equal to the height of the contact portion, thereby achieving the purpose of minimum design height.

[0012] The aforementioned low-profile sheet contact, the wire pressing portion 10 includes a wire groove 7 for accommodating the wire and a first fixing plate 8 and a second fixing plate 9 spaced apart on both sides of the wire groove 7 to achieve fixation of different positions in the length direction of the wire and ensure reliability of fixation.

[0013] The aforementioned low-profile sheet-type contact piece is integrally formed.

[0014] Compared with the prior art, the utility model has obvious advantages and beneficial effects. By means of the above technical solution, the utility model can achieve considerable technical progress and practicality, and has wide industrial utilization value, and has at least the following advantages:

[0015] The utility model divides the bottom plate into a front section and a rear section along the length direction, and the extension directions of the front section and the rear section are consistent and maintain an angle of 90-180 degrees with the transition section for connecting the front section and the rear section, thereby allowing the contact portion on one side of the front section and the wire pressing portion on one side of the rear section to form a low contact piece, and at the same time ensuring the stable assembly of the contact piece in the insulator to meet the use requirements.

[0016] When the rear section of the bottom plate of the utility model is offset toward the contact portion relative to the front section, the overall height of the contact piece is further reduced and is substantially equal to the height of the contact portion, thus meeting the requirement of small size.

[0038] See also Figure 1-3 , which is a schematic diagram of the structure of each part of a low-profile sheet contact of the first embodiment of the utility model, the contact comprises a top plate 1, the top plate 1 is provided with a front section 101, a transition section 102 and a rear section 103 in sequence along the length direction, wherein the front section 101 and the rear section 102 extend in the same direction and are not on the same plane, the transition section 103 realizes the connection between the front section 101 and the rear section 102 and has an angle θ of 90 to 180° between the front section 101 and the rear section 102. In this embodiment, the front section 101 and the rear section 102 both extend along the a direction.

[0039] A contact portion 11 is formed on one side of the front section 101 perpendicular to its extension direction, which is used to be plugged and matched with the plug-in contact piece, and a wire pressing portion 10 is formed on one side of the rear section 102 perpendicular to its extension direction, which is used to realize the wire pressing of the tail of the contact piece. In this embodiment, the top plate 1 is flat, and the contact portion 11 and the wire pressing portion 10 are located on different sides of the flat top plate 1. In this embodiment, the rear section of the top plate 1 is offset relative to the front section 101 to the side where the wire pressing portion 10 is located, so that the transition section 103 is an inclined surface that gradually rises from front to back. In another embodiment of the utility model, the rear section 102 of the top plate 1 is offset relative to the front section 101 to the side where the contact portion 11 is located, so that the transition section is an inclined surface that gradually descends from front to back. At this time, the size of the contact piece in the height direction is further reduced, and the overall height of the contact piece is approximately equal to the height of the contact portion 11.

[0040] In this embodiment, the wire pressing part 10 includes a wire groove 7 and first fixing plates 8 located on both sides of the wire groove 7. The wire groove 7 is formed by the rear section of the top plate 1 and the stop edges formed by folding up the two sides of the rear section.

[0041] The contact portion 11 includes two side plates 2 extending from both sides of the lower end of the front section 101 of the top plate 1. A first elastic arm 3 extending downward also extends from the lower side of the side plate 2. The two first elastic arms 3 arranged opposite to each other form a sheet-type jack structure for inserting the adapter end contact. In order to enhance the elasticity of the first elastic arm 3, the first elastic arm 3 extends downward from the root connected to the side plate 2 and approaches the other first elastic arm along its extension direction, and the position of the first elastic arm 3 near the end is bent toward the direction of the other first elastic arm 3 to form an elastic contact portion 31 for elastically contacting the adapter end contact, and the end of the first elastic arm 3 is bent toward the side away from the other first elastic arm 3 to form a guide portion 32 for guiding the insertion of the adapter end contact.

Preferably, the second elastic arm 6 is integrally formed with the front plate 5.

[0043] In order to enhance the stability of the contact piece of the utility model and prevent the contact part 11 from swinging when the plug end is plugged in, the contact part 11 includes a side panel extension extending downward from the bottom of the side panel 2, and the first elastic arm 3 is located between the front panel 5 and the side panel extension. The anti-swing positioning of the contact part 11 in the insulator mounting hole is achieved through the cooperation between the front panel 5 and the side panel extension and the insulator (the anti-swing is achieved through the cooperation between the side end surfaces of the front panel and the outer end surfaces of the side panel extension and the insulator). At the same time, the setting of the side panel extension makes the first elastic arm 3 between the front panel 5 and the side panel extension during installation, which can prevent the first elastic arm from directly contacting the insulator and ensure that the first elastic arm 3 is not damaged during assembly.

[0044] See also Figure 4-6 , which is a schematic diagram of the structure of each part of the second embodiment of the utility model. In this embodiment, the contact portion 11 and the wire pressing portion 10 are located on the same side of the top plate 1. In this embodiment, the end of the side plate extension portion 4 is bent toward the direction of the other side plate extension portion 4 to enhance the stability of the side plate extension portion, thereby enhancing the stability of the side plate extension portion 4 and the insulator, but it is not limited to this.

[0045] In this embodiment, the contact piece's crimping and insertion with the adapter contact piece are completed on the same side of the top plate 1, and the rear section of the top plate 1 is also offset to this side relative to the front section. At this time, the height of the contact piece reaches the minimum, which is the height of the contact portion 11.

[0046] In the embodiment of the utility model, the front plate 5 is formed by folding the front end of the top plate 1 downwards, and the side plates 2 are formed by folding both sides of the top plate 1 downwards.
