Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicle-mounted connectors, in particular to a vehicle-mounted connector CPA with an anti-fracture structure. Background Art
[0002] A connector is a component that is attached to a cable or installed on an instrument. It serves as a component for electrically connecting or separating transmission lines. As the automotive industry becomes increasingly intelligent and networked, it is also equipped with more and more information equipment.
[0003] High-speed vehicle-mounted connectors are high-speed vehicle-mounted connectors that have appeared in recent years. This type of connector is mainly used in autonomous driving to meet the increasingly high communication speed requirements of autonomous driving, and the requirements for high bandwidth, high rate, and high reliability transmission are getting higher and higher.
[0004] After mating, traditional automotive data connectors are fixed with a CPA with a double-sided snap-on structure. The CPA can be assembled by simply inserting it from the rear of the connector into the required position. However, similar cantilever beam structure snaps are prone to offset when inserted into the connector. A slight offset will cause the deformation of the single-sided snap to exceed its tolerable bending limit. In the offset state, the snap may also bend in the opposite bending direction, causing damage or even breakage of the cantilever beam snap, affecting product quality.
[0005] In summary, there is an urgent need to provide a vehicle-mounted high-speed connector plug-in retaining structure that can more firmly fix the connector and avoid excessive gaps at the connection compared to the existing technology. Utility Model Content
[0006] In order to overcome the problems existing in the prior art, the purpose of the present invention is to provide a vehicle-mounted connector CPA with an anti-fracture structure, increase the deformation of the CPA cantilever beam buckle, ensure structural stability, and prevent breakage during use.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a vehicle-mounted connector CPA with an anti-fracture structure, comprising a CPA body, an elastic snap buckle, a support surface, and a limit surface; the elastic snap buckle is located on both sides of the CPA body, the support surface and the limit surface are located in the gap between the CPA body and the elastic snap buckle, and the support surface and the limit surface are both connected to the CPA body.
[0008] The present invention is further configured as follows: the elastic buckle is a cantilever beam structure, the tail end of the elastic buckle is connected to the CPA body, and the head of the elastic buckle extends toward the insertion direction of the CPA body.
[0009] The present invention is further configured as follows: the support surface is arranged relative to the middle section of the elastic buckle, and in an unassembled state, a certain gap is maintained between the support surface and the elastic buckle.
[0010] The present invention is further configured such that: the limiting surface is arranged at a position relative to the head portion of the elastic buckle, and in an unmounted state, a certain gap is maintained between the limiting surface and the elastic buckle.
[0011] The present invention is further configured as follows: the support surface protrudes from the limit surface, and the support surface and the limit surface are transitioned by an arc.
[0012] The present invention is further configured as follows: at least one set of the elastic buckles, the supporting surface and the limiting surface is respectively provided on both sides of the CPA body.
[0013] The present invention is further configured as follows: the vehicle-mounted connector CPA further includes a buckle protection beam, which is arranged at the front end of the elastic buckle along the insertion direction of the CPA body, and the buckle protection beam is connected to the CPA body.
[0014] The utility model is further configured as follows: the vehicle-mounted connector CPA is formed by injection molding.
[0015] In summary, the beneficial effects of the above technical solution of the present utility model are as follows:
[0016] 1. The utility model can effectively prevent the elastic buckle from breaking due to transitional deformation by adding a limiting surface in the bending direction of the elastic buckle. At the same time, a supporting surface is added at the middle section of the cantilever beam of the elastic buckle, so that the cantilever beam of the elastic buckle bends at the supporting surface position, thereby reducing the bending deformation of the root of the cantilever beam. Under the condition of extremely limited product space, the bending limit of the elastic buckle can meet the use requirements of the product.
[0017] 2. The utility model provides a buckle protection beam to protect the elastic buckle during installation, thereby preventing the angle deviation from causing the elastic buckle to bend in the opposite bending direction during connection, causing damage or even breakage, which affects the quality of the product.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following is a clear and complete description of the technical solution of the present invention in conjunction with the drawings of the present invention. Based on the embodiments of the present invention, other similar embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention. In addition, the directional words mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional words used are used to illustrate rather than limit the invention of the present invention.
[0025] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.
[0026] Example:
[0027] like Figure 1-Figure 3 As shown in the figure, a preferred embodiment of the present invention is a vehicle-mounted connector CPA with an anti-fracture structure, comprising a CPA body 101, an elastic buckle 102, a support surface 103 and a limit surface 104; at least one set of the elastic buckle 102, the support surface 103 and the limit surface 104 is provided on both sides of the CPA body 101. Figure 1 、 Figure 2 As shown, in this embodiment, a group of elastic buckles 102, a supporting surface 103 and a limiting surface 104 are respectively provided on both sides of the CPA body 101.
[0028] The supporting surface 103 and the limiting surface 104 are located in the gap between the CPA body 101 and the elastic buckle 102 , and both the supporting surface 103 and the limiting surface 104 are connected to the CPA body 101 .
[0029] The elastic buckle 102 is a cantilever beam structure. The tail end of the elastic buckle 102 is connected to the CPA body 101 , and the head of the elastic buckle 102 extends toward the insertion direction of the CPA body 101 .
[0030] The supporting surface 103 is arranged relative to the middle position of the elastic buckle 102, and the limiting surface 104 is arranged relative to the head position of the elastic buckle 102. In the unassembled state, the limiting surface 103 and the supporting surface 104 maintain a certain gap with the elastic buckle 102.
[0031] The supporting surface 103 protrudes from the limiting surface 104 , and a circular arc forms a transition between the supporting surface 103 and the limiting surface 104 .
[0032] Adding a limiting surface 104 in the bending direction of the elastic clip 102 can effectively prevent the elastic clip 102 from breaking due to transitional deformation. At the same time, adding a supporting surface 103 at the middle section of the cantilever beam of the elastic clip 102 makes the cantilever beam of the elastic clip 102 bend at the support surface 103, thereby increasing the deformation of the elastic clip 102, ensuring structural stability, and preventing breakage during use.
[0033] The vehicle-mounted connector CPA100 further includes a snap-on protection beam 105 , which is disposed at the front end of the elastic snap 102 along the insertion direction of the CPA body 101 , and is connected to the CPA body 101 .
[0034] If an angled misalignment occurs during connection, the front end of the elastic clip 102 could collide with the vehicle connector housing 200, causing the elastic clip 102 to bend in the opposite direction, resulting in damage or even breakage. Therefore, a clip protection beam 105 is provided at the front end of the elastic clip 102 to prevent the top of the elastic clip 102 from directly contacting the vehicle connector housing 200 during installation. The clip protection beam 105 is also chamfered to facilitate the transition to the connection slot during connection.
[0035] In this embodiment, the vehicle connector CPA100 is formed by injection molding.
[0036] Combine Figure 3 As shown, the direction indicated by the arrow in the figure is the insertion direction of the vehicle connector CPA100. During use, the CPA body 101 is inserted into the vehicle connector housing 200 in the direction of the arrow. During the insertion process, the elastic clips 102 on both sides are squeezed and bend inward. At this time, the elastic clips 102 are pressed against the support surface 103 and bend again with the support surface 103 as the fulcrum, thereby reducing the bending deformation at the root of the cantilever beam and increasing the bending limit of the head of the elastic clip 102 under extremely limited product space conditions. When bent to a certain angle, the head of the elastic clip 102 contacts the limit surface 104, preventing the elastic clip 102 from breaking due to excessive deformation.
[0037] Finally, it should be noted that the above content is only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Simple modifications or equivalent replacements of the technical solution of the utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the utility model.
