Description

Technical Field

[0001] The utility model relates to the field of automobile brake parking, in particular to a parking motor housing connector. Background Art

[0002] China's invention patent publication number CN115370742A shows a car-use wire-controlled P-gear parking actuator, in which the parking motor is assembled in the housing and connected to the connector terminals on the outer edge through the connectors arranged inside the housing. In order to realize this arrangement structure, it is necessary to first make a metal connector body, and then place the connector in the housing injection mold for injection molding, so that the metal connector is integrated into the housing.

[0003] In order to simplify the work time of the positioning process in the secondary molding, the conventional method is to add an insulating connection bracket between the positive and negative metal connectors to combine the two connectors into one. However, since the connection bracket made by the recommended glue is small in size, it is easy to fall off. Utility Model Content

[0009] In a preferred embodiment of the present invention, the distance between the first lateral tooth groove and the second lateral tooth groove is 0.37 mm.

[0010] In a preferred embodiment of the present invention, the depth of the staggered tooth grooves is 0.15 mm.

[0011] In a preferred embodiment of the present invention, the slotting arc of the staggered tooth grooves is 60°.

[0012] In a preferred embodiment of the present invention, the bottom chamfer radius of the staggered tooth grooves is 0.05 mm.

[0013] In a preferred embodiment of the present invention, the side line surface distance from the connecting bracket to the first connector and the second connector is 0.8 mm.

[0014] The beneficial effects of the utility model are:

[0015] The utility model provides a parking motor housing connector, on which a toothed structure is arranged to increase the contact area with the connecting bracket, and at the same time, the toothed structure is in a horizontal and vertical staggered form to prevent the connector surface from being affected by the open teeth and causing failures such as breakage.

[0021] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by terms such as "longitudinal" and "lateral" are based on the orientations or positional relationships shown in the accompanying drawings. The above description is simplified for the convenience of describing the present invention, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0022] The singular forms "a", "said" and "the" used in the specification include plural forms unless clearly indicated. The terms "include", "comprises" and "comprising" used in the specification indicate the presence of the claimed features, but do not exclude the presence of one or more other features.

[0023] In the specification, when an element is said to be "on", "fixed" to, "connected" to, "engaged" to, etc., another element, the element may be directly on, fixed to, connected to, engaged to, or in contact with the other element, or there may be intervening elements. In the specification, when a feature is arranged "adjacent" to another feature, it may mean that the feature has a portion overlapping with the adjacent feature or a portion located above or below the adjacent feature.

[0024] The following will describe exemplary embodiments of the present application with reference to the accompanying drawings. However, it should be understood that the present application can be presented in a variety of different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all drawings, the same reference numerals represent the same or functionally identical elements.

[0025] refer to Figure 1 The parking motor housing connector shown mainly includes a first connector 1 and a second connector 2 for connecting to the positive and negative poles of the motor. Since the connector needs to be directly integrated into the motor housing by re-injection molding, a connecting bracket 3 needs to be provided between the first connector 1 and the second connector 2 to reduce the time required for repositioning the connector parts during the motor housing injection molding process.

[0026] The first connector 1 and the second connector 2 are both provided with toothed structures 110. Since the connection bracket 3 is made by injection molding with a simple injection mold, the toothed structures 110 are provided to increase the contact area with the connection bracket 3 to prevent it from falling off after molding.

[0027] refer to Figure 2 and Figure 3 The tooth structure 110 is mainly composed of a plurality of longitudinal protruding teeth 121 located on the longitudinal surfaces 120 parallel to each other on both sides of the first connector 1 or the second connector 2 and a plurality of staggered tooth grooves 131 on the lateral surfaces 130 adjacent to the longitudinal surfaces 120 and parallel to each other. Further, the staggered tooth grooves 131 include first lateral tooth grooves 132 and second lateral tooth grooves 133 located on two different lateral surfaces 130 and staggeredly arranged along the extending direction of the connector. The longitudinal protruding teeth 121 extend outward from the longitudinal surfaces 120 facing each other.

[0028] Figure 4An embodiment of staggered tooth grooves is shown. In order to ensure the strength of the connector when slotting, the slot spacing between the first lateral tooth groove 132 and the second lateral tooth groove 133 is 0.37mm, the slot depth of each tooth groove is 0.15mm, the slotting angle is 60°, and the bottom chamfer radius is 0.05mm. Furthermore, the injection molding thickness of the connecting bracket 3, that is, the distance from its lateral surface to the lateral surface 130, is 0.8mm. This ensures that the connecting bracket 3 is not easy to fall off after completion.

[0029] It is to be understood that although the terms "first", "second", etc. may be used herein to describe different elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element. Therefore, a first element may be referred to as a second element without departing from the teachings of the present application.
