Preferred embodiments of the present utility model are described in detail below, however, the present utility model may have other embodiments in addition to these detailed descriptions.

The utility model provides a data key. The conductive member 130 of the data key may be in contact with the wire-end connector so as to be electrically connected with an electrical component electrical connection wire-end connector for being located outside of a later-described housing, thereby being capable of transmitting electrical power with the wire-end connector. The conductive member 130 of the data key is injection molded and embedded in the housing 110. In this way, there is no need to provide mounting through holes in the housing 110 for mounting the conductive members provided with the conductive members 130. The data key has strong sealing performance.

The data key may be provided to the vehicle. The circuit board of the latter data key can be connected with the car key by wireless, and then communicate. When the vehicle key is at a preset distance from the data key, the data key can receive a signal of the vehicle key, and then the vehicle key enters an unlocking mode. Upon entering the unlocked mode, the vehicle may be operated, such as to open a door.

Referring to fig. 1 to 5, the data key includes a housing 110. The housing 110 is a plastic piece. Thus, the housing 110 is lightweight. The housing 110 includes a body 111. The body 111 includes a side wall 112 and a bottom wall 113. The side wall 112 is configured as a circumferentially closed annular structure. Along the axial direction D1 of the side wall 112 (i.e., the height direction of the body 111), the bottom wall 113 is connected to one end of the side wall 112 to close one end of the side wall 112. In this way, the bottom wall 113 and the side wall 112 form an inner space of the body 111 and a body opening communicating with the inner space of the body 111. Thus, the strength of the body 111 is high.

As shown in fig. 1-5, sidewall 112 has damascene wall 114. The data key also includes a conductive member 130. The conductive member 130 may be a metal member. For example, the conductive member 130 is a copper alloy member. Preferably, the conductive member 130 may be a PIN (Pin needle) needle. The conductive member 130 has an inner end 134 and an outer end 133. The conductive element 130 is injection molded and embedded in the embedded wall 114.

It should be noted that, the manner of injection molding and embedding refers to that the metal piece (the conductive piece 130) is placed at a preset position in the injection molding process of the injection mold, and after injection molding and cooling molding, the metal piece is embedded at a corresponding position of the injection molding shell (the embedded wall 114) to form a stable structure on the injection molding shell.

The conductive member 130 and the housing 110 constitute a unitary structure. The conductive member 130 cannot be detached from the housing 110 without the housing 110 being damaged.

The inner end 134 is located at an inner side of the inlaid wall 114 proximate the interior space of the body 111. The outer end 133 is located outside of the inlay wall 114 away from the interior space of the body 111. The wire end connector may contact the outer end 133 so as to be electrically connected with the outer end 133.

Preferably, as shown in fig. 1, 3 to 5, the body 111 is constructed in a substantially rectangular parallelepiped structure. One wall of the side walls 112 is configured as a mosaic wall 114. The plane of the inlaid wall 114 is perpendicular to the longitudinal direction D2 of the body 111. Thereby, the structure of the body 111 is simple.

With continued reference to fig. 1-5, the data key further includes a circuit board 140. The circuit board 140 is disposed in the inner space of the body 111. The circuit board 140 is a generally rectangular plate. The plane of the circuit board 140 is perpendicular to the axial direction D1 of the side wall 112. The length direction of the circuit board 140 is substantially parallel to the length direction D2 of the body 111. The width direction of the circuit board 140 is substantially parallel to the width direction D3 of the body 111.

Circuit board 140 is electrically connected to inner end 134. Thus, inner end 134 is electrically connected to circuit board 140. The wire end connector located outside the body 111 can be electrically connected to the circuit board 140 located inside the body 111 via the conductive member 130, and thus can transfer electric power with the circuit board 140.

As shown in fig. 1 and fig. 3 to 5, along the length direction D2 of the body 111, the damascene wall 114 extends and protrudes away from the inner space of the body 111 to form a connection portion 115. The connection portion 115 is a circumferentially closed ring structure. The free end of the connection portion 115 is open. The connecting portion 115 is sleeved on the outer end 133.

The line-end connector can extend into the connection portion 115 and be connected to the connection portion 115. At this time, the wire end connector contacts the outer end 133 of the conductive member 130 to be electrically connected with the conductive member 130. In this way, the connection portion 115 can support the line-end connector electrically connected to the conductive member 130. Further, the strength of the connection portion 115 is large. The connection portion 115 can protect the outer end 133 of the conductive member 130.

In the present embodiment, the conductive member 130 is injection-molded and embedded in the embedded wall 114, the inner end 134 of the conductive member 130 is located in the embedded wall 114, and the outer end 133 of the conductive member 130 is located outside the embedded wall 114, so that it is not necessary to provide an installation through hole for installing the conductive member 130 on the housing 110, and the sealing performance of the data key can be improved.

Preferably, the outer end 133 is located between the free end of the connecting portion 115 and the inlay wall 114 in the axial direction of the connecting portion 115 (the axial direction of the connecting portion 115 is parallel to the length direction D2 of the body 111). That is, the outer end 133 is located within the connection portion 115. Thereby more effectively protecting the outer end 133 of the conductive member 130.

Along the axial direction D1 of the side wall 112, one end of the connecting portion 115 is located at the bottom wall 113, and one end of the connecting portion 115 remote from the bottom wall 113 is located between both ends of the side wall 112.

As shown in fig. 1, 3 to 5, the connection portion 115 has a substantially elliptical structure. The long axis direction of the connection portion 115 is substantially parallel to the width direction D3 of the main body 111. Thus, the strength of the connection portion 115 is high.

As shown in fig. 2, 4 and 5, the conductive member 130 includes a first segment 131 and a second segment 132. The first segment 131 and the second segment 132 are each rod-like structures. The length direction of the first segment 131 and the length direction of the second segment 132 form an intersection angle. One end of the first section 131 is connected to one end of the second section 132. The other end of the first segment 131 is an inner end 134. The other end of the second section 132 is an outer end 133. In this way, the first and second sections 131 and 132 are configured in a generally L-shaped configuration, facilitating connection of the conductive member 130 to the circuit board 140.

The second section 132 has a locating hole 135. Along the length of the second section 132, the maximum distance between the locating hole 135 and the first section 131 is greater than the maximum distance between the locating hole 135 and the outer end 133. The positioning hole 135 is located in the housing 110. The axial direction of the positioning hole 135 is substantially parallel to the axial direction D1 of the side wall 112. Thus, when the housing 110 is processed, the conductive member 130 may be positioned through the positioning hole 135, and then the conductive member 130, the body 111 and the connection portion 115 are injection molded into one piece through an injection molding process. Thereby facilitating the processing of the housing 110.

As shown in fig. 4 and 5, the length of the first segment 131 is preferably parallel to the plane of the mosaic wall 114. The length direction of the first segment 131 is parallel to the axial direction D1 of the sidewall 112. The length of the second segment 132 is perpendicular to the plane of the mosaic wall 114. Thereby, the structure of the housing 110 is simple.

Preferably, as shown in fig. 1 and 4, the circuit board 140 has conductive vias 141. The inner end 134 is disposed through the conductive via 141. Thereby facilitating connection of the circuit board 140 and the conductive member 130.

Referring back to fig. 1, 3-5, the data key further includes a cover 150. The cover 150 is a plastic member. The cover 150 is connected to an end of the side wall 112 remote from the bottom wall 113. The cover 150 covers the body opening. The cover 150 is coupled to the sidewall 112 by a glue. This can improve the sealing property of the joint between the lid 150 and the body 111.

It will be appreciated that in an embodiment not shown, the cover may also be attached to the side wall by ultrasonic welding.

Further preferably, as shown in fig. 4 and 5, along the axial direction D1 of the side wall 112, the end surface of the side wall 112 remote from the bottom wall 113 is recessed toward the bottom wall 113 to form a groove 120. The groove 120 is a circumferentially closed annular structure extending in the extending direction of the side wall 112. Along the axial direction D1 of the side wall 112, a surface of the cover 150 facing the bottom wall 113 extends to protrude toward the bottom wall 113 to constitute a projection 151. The projection 151 is a circumferentially closed ring-shaped structure. The projection 151 protrudes into the recess 120. This can further improve the sealability of the data key. In addition, the connection between the cover 150 and the body 111 is firm.

It will be appreciated that in an embodiment not shown, the cover may also be provided with a recess. At this time, the side wall is provided with a protrusion.

The ribs 116 are attached to the inner surface of the side wall 112. The ribs 116 are connected to the bottom wall 113. Thus, the strength of the body 111 is high.

The end surface of a portion of the rib 116 remote from the bottom wall 113 is a landing surface 121. The circuit board 140 is lapped to the lapping surface 121. Thus, the partial ribs 116 support the circuit board 140 together with the later mounting portion 117, facilitating the mounting of the circuit board 140.

The body 111 is provided with a mounting portion 117 inside. The mounting portion 117 is configured such that an inner surface of the bottom wall 113 is formed to extend toward one end of the side wall 112 away from the bottom wall 113. The mounting portion 117 is located in the inner space of the body 111. The mounting portion 117 is injection molded with a nut. The mounting portion 117 is located below the circuit board 140.
