Description

Technical Field

[0001] The utility model relates to the technical field of vehicle connectors, and particularly relates to a connector and a radar. Background Art

[0002] A millimeter-wave radar is a radar that operates in the millimeter-wave band. Generally, millimeter waves refer to those in the frequency range of 30 - 300 GHz (wavelength of 1 - 10 mm), and are widely used in automotive advanced driver assistance systems. Due to the continuous improvement of automotive radar in terms of functional parameters and other aspects, corresponding to the increase in power consumption, the conventional all-plastic structure can no longer meet the current product's heat dissipation requirements. Most high-resolution radar products have been comprehensively upgraded from the all-plastic structure to the metal bottom shell structure, which can further increase the self-heat dissipation of the radar.

[0003] Traditional radar products usually adopt a metal bottom shell structure. When electrically connecting with a connector, the connector often uses a single-row multi-pin electrical component to transmit electrical energy to the radar product. Since there is a lot of signal interaction between the current radar and the vehicle, the single-row multi-pin design depends more on the structural size space to meet the signal requirements. In the industry trend of the vehicle radar tending to be small in volume, it cannot meet the application environment of small-volume radars, and the flexibility of use is low. Summary of the Utility Model

[0004] The main purpose of the utility model is to propose a connector and a radar, aiming to solve the technical problems of how to improve the electrical signal transmission ability and how to update and break through the fastening and sealing between the connector and the bottom shell when the traditional radar adopts a metal bottom shell.

The two card slots are symmetrically distributed on both sides of the first connection section. Each card slot has a circular cross-section, and each card slot is used for bolt connection with the docking groove.

[0011] In one embodiment, the first connection section is provided with a connection boss upward, and an annular boss is provided around the outer periphery of the connection boss. The annular boss is used to abut against the peripheral edge of the docking groove when the connection boss is inserted into the docking groove.

[0012] In one embodiment, annular grooves are provided on both sides of the annular boss, and the annular grooves are fixedly arranged around the first connection section.

[0013] In one embodiment, the connector further includes a sealant, and the sealant is filled in the annular groove. The sealant is used to seal the connector and the radar.

[0032] The present utility model provides a connector 1.

[0033] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, the connector 1 is applied to a radar 2. The radar 2 has a docking slot 21 connected to the connector 1. The connector 1 includes a housing 11 and an electrical component. An installation cavity 111 is formed in the housing 11; the electrical component includes two rows of pins arranged side by side at intervals, and each row of pins is arranged in the installation cavity 111 and integrally formed with the housing 11.

[0034] In this embodiment, the connector 1 is mainly used to connect the automotive radar 2 product. The housing 11 is used to provide physical support for the electrical component. The electrical component arranged in the installation cavity 111 can prevent the influence of the external environment on the internal electrical component. The housing 11 is made of plastic material, and the electrical component is made of metal material. The electrical component and the housing 11 are integrally formed to form a connector pin assembly.

[0035] The technical solution of the present utility model makes the structure of the entire connector 1 more compact by arranging the two rows of pins 12 in the installation cavity 111 and integrally forming them with the housing 11. The two rows of pins 12 arranged side by side at intervals ensure the stability and reliability of the electrical connection, can provide more electrical connection points, contribute to realizing complex circuit connections, ensure the transmission of electrical signals, reduce the problems of poor contact or signal interference, thereby improving the electrical signal transmission ability and achieving a more stable electrical connection.

[0036] In an embodiment of the present utility model, the two pin rows 12 include a first pin row 121 and a second pin row 122. The first pin row 121 and the second pin row 122 are arranged at intervals and correspond to each other. Both the first pin row 121 and the second pin row 122 include a plurality of pins, and the plurality of pins are arranged side by side at intervals.

One end of the electrical component passes through the first connection section and connects to the docking groove 21, and the other end of the electrical component extends out from the second connection section. In this embodiment, the installation cavity 111 is used to accommodate and fix the electrical component and is made of an insulating material. Through the above arrangement, the connection stability is enhanced, and the installation flexibility is also improved. The tight connection between the electrical component and the docking groove 21 ensures the stable transmission of electrical signals, reduces signal loss and interference, and improves the electrical performance.

[0038] Combined with Figures 3 to 4 , in an embodiment of the present utility model, at least two card slots 1112 are provided at one end of the installation cavity 111 close to the radar 2. The two card slots are symmetrically distributed on both sides of the first connection section. Each cross-section of the card slots 1112 is circular, and each card slot 1112 is used for bolt connection to the docking groove 21. In this embodiment, the cross-section of the card slot 1112 is designed to be circular, which helps the insertion and fixation of the bolt and provides better bolt connection stability.

[0039] In an embodiment of the present utility model, a connecting boss 1113 is provided upward on the first connecting section.
