Description

Technical Field

[0001] This application belongs to the field of electrical connector technology, and in particular relates to a miniature strip connector that prevents loosening. Background Technology

[0002] In precision equipment such as miniature high-speed slip ring actuators, brush filaments and wires need to transmit electrical signals through miniature connectors. Such applications must have three core characteristics: first, space is extremely limited, requiring miniaturization of the connector; second, vibration and impact are severe, with vibration acceleration often reaching 30g or more; and third, channel density is high, requiring multiple contacts to conduct electricity stably at the same time. In existing technologies, a common connection method using ordinary connectors and sockets is used. Because the connectors only have a single mating surface in contact, the contact area is small, resulting in poor conductivity stability. In addition, this connection method is prone to failure due to friction under high vibration environments, causing the connectors to loosen, which in turn leads to signal loss and seriously affects the normal operation of the equipment. Utility Model Content

[0003] To address the technical problems of ordinary power strips with female connectors having only a single mating surface for contact, resulting in a small contact area and poor conductivity, and the tendency for friction to fail under high vibration environments, leading to loosening of the connectors, signal loss, and serious impact on the normal operation of equipment, this utility model provides a miniature strip connector with anti-loosening feature.

[0004] In a first aspect, this application provides a micro strip connector designed to prevent loosening, comprising: A male connector assembly, comprising a male connector body, the front end of which is provided with a plurality of pins arranged in a linear array, and the sides of which are provided with retaining sleeves; A female connector assembly, comprising a female connector body, the front end of which is provided with a socket matching the pin array, and the two sides of which are provided with elastic clips matching the clip sleeve; The male and female connectors are provided with mutually engaging limiting components on their opposite ends.

[0005] According to an embodiment of this application, a miniature strip connector designed to prevent loosening is provided. This connector features multiple circumferentially arranged annular blocks fixed to the outside of an elastic locking head, which engage with mounting holes in a locking sleeve. The locking post and slot in the limiting component form a double-layer locking structure to prevent the male connector assembly from separating from the female connector assembly.

[0006] According to one embodiment of this application, the limiting component includes a locking post and a locking groove. The locking post is fixed to both sides of the front end of the female head body, and the locking groove is formed on both sides of the front end of the male head body. The locking head engages in the locking groove.

[0007] According to one embodiment of this application, the locking post is made of an elastic material, and the front end of the locking post is wedge-shaped, the locking groove is L-shaped, and the wedge-shaped inclined surface of the locking post abuts against the external corner of the locking groove.

[0008] According to one embodiment of this application, a connecting plate is fixedly attached to the outer side of the locking post.

[0009] According to one embodiment of this application, the outer side of the cartridge is provided with circumferentially arranged mounting holes, and the outer side of the top of the elastic clip is fixed with a plurality of annular blocks that abut against the mounting holes.

[0010] According to one embodiment of this application, both ends of the male head body and the female head body are fixedly connected with strong magnets that attract each other.

[0011] Secondly, this application provides a miniature strip connector that prevents loosening; Including at least one of the following beneficial technical effects: 1.

[0016] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0017] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: This embodiment specifically describes the structure of a micro strip connector designed to prevent loosening, such as... Figures 1-4 As shown, it includes a three-part structure: male connector assembly 1, female connector assembly 2, and limiting assembly; Male connector assembly 1 includes a male connector body 101, with a plurality of pins 102 arranged in a linear array at the front end of the male connector body 101, and retaining sleeves 103 on both sides of the male connector body 101; female connector assembly 2 includes a female connector body 201, with a socket 202 at the front end that matches the pin array 102, and elastic retaining heads 203 on both sides of the female connector body 201 that match the retaining sleeves 103; limiting components that engage with each other are provided on the opposite ends of the male connector assembly 1 and the female connector assembly 2.

[0018] The entire equipment assembly process is as follows: The connector composed of male connector 1 and female connector 2 can be made in a corresponding proportion according to actual needs, and the size of the connector can be changed by reducing or increasing the number of pins 102 and sockets 202 as needed. Before insertion, connect the two cables to the male connector body 101 and the female connector body 201 respectively. Then, align the multiple pins 102 arranged in a linear array at the front end of the male connector body 101 with the sockets 202 of the female connector body 201. At this time, the retaining sleeves 103 on both sides of the male connector body 101 are also aligned with the elastic retaining heads 203 of the female connector body 201. The retaining posts 3 fixed to the front ends of the female connector body 201 are aligned with the retaining grooves 4 opened on the front ends of the male connector body 101. Once inserted, the pin array 102 is precisely inserted into the socket 202. The elastic clip 203 and the ring block 7 are engaged in the mounting hole 6 opened in the clip cylinder 103 under the action of elastic reset force. Similarly, under the action of elastic reset force, the wedge-shaped inclined surface at the front end of the clip post 3 will press against the yang corner inside the clip groove 4, further locking the connection between the male connector assembly 1 and the female connector assembly 2. Meanwhile, the wedge-shaped inclined surface at the front end of the locking post 3 abuts against the inner corner of the locking groove 4, which enables the male head assembly 1 and the female head assembly 2 to be tightly connected without any gaps.

[0019] In some examples, such as Figure 1 and Figure 4As shown, the limiting component includes a locking post 3 and a locking groove 4. The locking post 3 is fixed to both sides of the front end of the female head body 201, and the locking groove 4 is opened on both sides of the front end of the male head body 101. The locking head is engaged in the locking groove 4.

[0020] In some examples, such as Figure 3 As shown, the locking post 3 is made of elastic material, and the front end of the locking post 3 is wedge-shaped, while the locking groove 4 is L-shaped. The wedge-shaped inclined surface of the locking post 3 abuts against the external corner of the locking groove 4.

[0021] In some examples, such as Figure 4 As shown, the outer side of the cassette 103 is provided with circumferentially arranged mounting holes 6, and the outer side of the top of the elastic cassette 203 is fixed with multiple annular blocks 7 that abut against the mounting holes 6.

[0022] It is understandable that by fixing multiple circumferentially arranged annular blocks 7 to the outside of the elastic clip 203 and engaging with the mounting holes 6 opened in the clip cylinder 103, and by setting the wedge-shaped inclined surface at the front end of the clip post 3 to press against the inner corner of the clip groove 4, a double-layer locking structure is formed, which can further improve the prevention of connection between the male connector assembly 1 and the female connector assembly 2.

[0023] In some examples, such as Figure 3 As shown, a connecting plate 5 is fixed to the outside of the locking post 3, and a gap is left between the connecting plate 5 and the outside of the male head body 101.

[0024] It is understandable that the setting of the connecting plate 5, and the gap left between the connecting plate 5 and the outer side of the male head body 101, are all to facilitate the locking pin 3 to disengage from the slot 4, thereby detaching the male head body 101 from the female head body 201.

[0025] In some examples, such as Figures 2-3 As shown, strong magnets 8 that attract each other are fixed to both ends of the male head body 101 and the female head body 201.

[0026] The working principle of the anti-loosening miniature strip connector in this application embodiment is as follows: When the male connector assembly 1 is connected to the female connector assembly 2, the pins 102 are precisely inserted into the socket 202. The elastic locking heads 203 on both sides of the male connector, the multiple annular blocks 7, and the locking posts 3 made of elastic material are all deformed under pressure during the insertion process. When the insertion is in place, the elastic locking heads 203 and annular blocks 7 are locked into the mounting holes 6 opened in the locking cylinder 103 under the action of elastic restoring force, and the locking posts 3 are locked into the slots 4 under the action of elastic restoring force. The wedge-shaped locking posts 3 and the slots 4 are locked together. In addition, the male connector body 101 and the female connector body 201 are fixedly connected with strong magnets 8 that attract each other, which can still ensure the connection stability and prevent loosening.
